ABSTRACT

This study aimed to evaluate the effects of calcium propionate (PrCa), PrCa + monensin sodium (PrCa + Mon), and PrCa + Saccharomyces cerevisiae (PrCa + Sc) on the productive performance of Holstein steers. Twenty-four Holstein steers (270.0 ± 25.85 kg) were distributed individually into four treatments of six replicates. The treatments were control (no additives), PrCa (10 g/kg), PrCa + Mon (10 g/kg + 30 mg/kg), and PrCa + Sc (10 g/kg + 12.8 × 109 cfu). The steers were fed for 43 days, and afterwards, nutrient intake and digestibility as well as volatile fatty acids were determined, while the weight gained, feed efficiency, and CH4 production were calculated. Diet of PrCa + Sc had the highest (P < 0.0001) acid detergent fiber intake and propionate acid as well as the nutrient digestibility, with lowest (P < 0.0001) rumen acetic acid, methane, and protozoa concentration versus other diets. In conclusion, dietary inclusion of PrCa + Sc (10 g/kg + 12.8 × 109 cfu) improved nutrient digestibility, rumen fermentation, and reduced methane emission, thereby enhancing the possibility of ecofriendly ruminant farming.

ABSTRACT

The objective of this review was to analyze the effect of dietary selenium on oxidative stress in horses by considering past and recent bibliographic sources. Some research was done on oxidative stress, related pathologies and how selenium regulates oxidative stress. Oxidizing molecules are molecules that can accept electrons from the substances with which they react. Oxidizing These molecules, of oxidizing, are found naturally in any organism, and there are antioxidant mechanisms that regulate its activity. However, when the body is stressed, oxidizing molecules outperform the antioxidants, causing an imbalance known as oxidative stress. Among antioxidant molecules, selenium can act as an important antioxidant in the body. The antioxidant activity is based on an enzyme called glutathione peroxidase, which depends on selenium and controls the activity of oxidizing molecules.

ABSTRACT

This study was conducted to evaluate the impact of dried moringa leaves (DML) on semen quality, immunoglobulin measurements, blood metabolic analysis, antioxidant status and sex hormones of V-line rabbit bucks. Twenty-four mature rabbit bucks of 7-8 months-old of proven fertility with an average weight (2.8 ± 0.4 kg) were classified into four treatments (basal diet with 0, 750, 1500 and 3000 mg DML/kg diet) and 6 bucks per treatment were used. Seminal plasma cholesterol (p = 0.013) and triglycerides (p = 0.0001) of all moringa supplemented rabbits were higher than the control. Moringa leaves enhanced (p < 0.05) serum testosterone, follicle stimulating hormone and luteinizing hormone. Total antioxidant capacity, superoxide oxidase, glutathione peroxidase and catalase in seminal plasma of moringa rabbits were higher (p < 0.05) than the control. Serum total lipid (p = 0.002), cholesterol (p = 0.008), triglycerides (p = 0.019) and blood urea (p < 0.05) were lower in DML rabbits. Moringa leaves improved total antioxidant capacity (p = 0.0001), glutathione peroxidase (p = 0.0001) and superoxide oxidase (p = 0.037) in rabbits versus control. Rabbits consuming DML had higher (p < 0.05) immunoglobulin IgG and IgM than control. Results suggest that DML improved rabbits' antioxidant, and immunological status, semen quality, and sex hormones, but DML (750 mg/kg diet) is recommended because it was more effective than the other two high doses.

ABSTRACT

This study aimed to evaluate the dietary administration of the Caesalpinia coriaria (CC) extract for 30 days on in vitro fecal greenhouse gases production. Fecal samples, as inoculums, were collected from horses given daily 0- (Fecal 0), 60- (Fecal 60) and 120- (Fecal 60) mL CC aqueous extract per animal. The extract dose was mixed with the morning feeding diet at 6:00 h for each horse. During incubation, 0-, 0.6-, 1.2- and 1.8-mL CC extracts were added to the basal diet which was fed to horses (as subtract) and evaluated with each fecal type. Feces from the horses given no CC extract produced the lowest (P = .0014) methane while the fecal from horses given CC produced more methane . It was also observed that all CC doses linearly (P = .0457) produced more methane than the control. Furthermore, Fecal 0 was more efficient and produced less methane for every unit of metabolizable energy, organic matter, and short chain fatty acids while Fecal 60 was the least efficient. Production of H2S showed that feces of equine orally give 60 mL/day CC produced the highest while Fecal 0 and Fecal 120 were similar. Fecal type x dose showed that 0 mL/g DM produced the highest H2S while 1.8 mL/g DM produced the lowest. Thus, based on gas production, H2S, CO and CH4, feeding horses with 60 mL/day of CC with or without 0.6 mL/g DM of CC extract is recommended for the sustainable mitigation of greenhouse gases emission in horses.

ABSTRACT

This study investigated the effect of potato peel extract (PPE), orally administrated to rabbits, on serum blood metabolites and ameliorating oxidative stress induced by cold stress under Egyptian winter conditions. Twenty-four bucks grouped into three treatments (8 animals per group) were used for the experiment. The animals received 1.5 ml of water orally, containing 0 (PPE0), 25 (PPE25) or 50 (PPE50) mg PPE/kg live weight. Bucks were randomly assigned into three homogenous equal groups according to the level of PPE. Treatments were applied to each animal every two days over a period of three months including one month as an adaptation period. At the 8th week of the experiment, blood samples were collected from each buck and at the end of the experiment, bucks were slaughtered, and some organs were collected and weighed. The PPE improved (p < 0.05) blood total protein, albumin, globulin and glucose. The blood concentration of total lipid, cholesterol, triglyceride, low density lipoprotein and very low-density lipoprotein (were increased (p < 0.02) in PPE rabbits. Furthermore, PPE extract doses decreased (p < 0.001) oxidant thiobarbituric reactive substance (TBARS) in both blood and liver. Other liver and blood antioxidant system enzymes such as catalase, glutathione peroxidase, and superoxide dismutase were improved (p < 0.005) by PPE supplementation. Overall, oral administration of PPE up to 50 mg/kg live weight can have positive effects on rabbit health under cold stress.

ABSTRACT

Application of phytogenic feed additives in livestock production is a sustainable practice and the search for more phytogenic options continues. This study was conducted to investigate the impact of lemongrass supplementation on nutrient utilization, rumen fermentation and milk production and composition. Thirty gestating Farafra ewes were randomly assigned to three experimental treatments of control (without a supplement), or with the supplementation of 5 g (LEM5 treatment), or 10 g of lemongrass/ewe/d (LEM10 treatment) for 12 weeks. Lemongrass supplementation at both doses did not influence ( p > 0.05) nutrient intake, but improved nutrient digestibility (p < 0.05). Furthermore, LEM5 and LEM10 treatments improved (p ≤ 0.001) ruminal total volatile fatty acids, acetate and propionate. Blood glucose was increased (p < 0.05) and cholesterol was decreased in ewes supplemented with lemongrass at both doses. Milk yield, energy corrected milk yield, and milk component were improved (p ≤ 0.001) in ewes supplemented with lemongrass at 5 and 10 g while the feed efficiency was decreased. Lemongrass supplementation at both doses increased (p = 0.040) the proportion of milk total conjugated linoleic acid without affecting other milk fatty acids. In most of the parameters evaluated, there was no significant difference between LEM5 and LEM10. Therefore, lemongrass supplementation at 5 g/ewe/d can be used in dairy production with positive impacts.

ABSTRACT

Raising sheep and goats in the gulf region is a large entrepreneurial business. This is, of course, derived from the big demands of lamb and goat meats for citizens and expatriates. There is a major population living in the rural desert areas whose main income steps from rising local sheep and goats. Despite large number of farmers into sheep production, the country still imports from foreign countries to meet augment local demand. Thus, improving local sheep production is a means to reduce the importation of sheep from foreign land. The low twinning rates in the main two indigenous breeds (i.e., Najdi and Noemi) in the region motivated the researchers to pursue an avenue for maximizing the neonatal outcomes is a contributing factor to low level of sheep proliferation in the region. Thus, pursuing an avenue for maximizing the neonatal outcome per female is a good strategy. Application of hormonal induction protocol support reproductive efficiency by improving viable twin birth in single-bearing ewes. By applying this method, several sheep raisers could retain their business more effectively.

ABSTRACT

In the race against deadly diseases, multiple drugs have been developed as a treatment strategy in livestock. Each treatment is based on a specific mechanism to find a suitable drug. Antibiotics have become a fundamental part of the equine industry to treat bacterial diseases. These antibiotics have specific doses and side effects, and understanding each parameter allows veterinarians to avoid or limit the adverse effects of such drugs. Use of antibiotics causes microbial imbalance, decreased microbial diversity and richness in both cecal and fecal samples. Antibiotics reduced metabolites production such as amino acids, carbohydrates, lipids, and vitamins, increased multi-resistant microbes, and gives opportunity to pathogenic microbes such as Clostridium perfringens and Salmonella spp., to overgrow. Therefore, appropriate use of these antibiotics in equine therapy will reduce the adverse consequence of antibiotics on cecal microbiota activities.

ABSTRACT

This study was conducted to evaluate the effect of time of feeding on production performance of West African Dwarf (WAD) goats. Two experiments involving twenty-seven goats (15 bucks and 12 gravid does) were conducted. In Experiment I, the bucks were randomly allocated into three treatments of five replicates and fed for 115 days. In experiment II, pregnant goat-does were randomly allocated into three experimental treatments of four replicates per treatment  1 month to kidding. Goats were either fed in the morning (06:00 h), afternoon (12:00 h), or evening (18:00 h) respectively under natural light cycles. In experiment I, dry matter intake, weight gain, carcass characteristic, and meat chemical composition were not affected (P > 0.05) by time of feeding. In experiment II, data collection on feed intake, feed efficiency (FE), and milk yield spanned 6 weeks and were analyzed. From the results, milk yield in morning-fed goat-does was higher than evening-fed does while afternoon-fed does have the lowest yield at P < 0.001. Energy corrected milk in evening-fed does was higher (P = 0.006) than other treatments. Feed efficiency for milk yield and energy corrected milk yield (P < 0.001) in evening-fed does were higher than morning and afternoon-fed does. Milk component yield (g/day) for lactose (P = 0.002) was the highest in morning-fed does; evening-fed does had the highest (P = 0.001) crude fat while afternoon-fed does had the lowest yield for all milk component parameters. Conclusively, feeding in the morning and evening is recommended for milk production and component yield per day. However, for improved energy corrected milk yield and feed efficiency in lactating goats, feeding in the evening is recommended. It is recommended that further studies should be conducted on improving milk productivity in evening-fed goats due to the advantage it had over other feeding regimes. Thus, altering time of feeding could be a suitable alternative feeding strategy in a changing climate with a potential to improve production efficiency, especially in the tropics.

ABSTRACT

The study aims to evaluate the effect of aqueous and methanolic extracts of three herbs, namely, neem (Azadirachta indica), drumstick (Moringa oleifera) and scent (Ocimum gratissimum), and three spices garlic (Allium sativum), ginger (Zingiber officinale) and onion leaflets (Allium cepa) on ruminal methane production and fermentation characteristics. The feed samples (200 mg substrates plus extracts of the selected herbs and spices) were incubated with rumen liquor taken from three mature West African dwarf ewes at 3, 6, 9, 12, 15, 18, 21 and 24 h. The results show that extracts of the selected herbs and spices increased the gas produced, from the insoluble fraction, degradability rate, volume of gas produced at time and time of most rapid change in gas produced. The organic matter digestibility (OMD), metabolizable energy (ME) and short-chain fatty acid (SCFA) contents of aqueous extracts of the selected herbs and spices (1 ml/200 mg substrates samples) were between 32.82 and 71.34 g/100 g OM, 4.10 and 10.25 MJ/kg DM and 0.28 and 1.31 µmol, respectively. Furthermore, the OMD, ME and SCFA contents of methanolic extracts of the selected herbs and spices (1 ml/200 mg substrates samples) were between 32.82 and 99.50 g/100 g OM, 4.10 and 14.37 MJ/kg DM and 0.28 and 2.07 µmol, respectively. Methane produced from the methanolic extracts of the herbs and spices highly differed (P < 0.05). This study suggests that extracts of the selected herbs and spices have the potential to affect rumen fermentation and also to reduce the methane production in sheep.

ABSTRACT

In a study to determine the growth-promoting effect of water-washed neem (Azadirachta indica A. Juss) fruit (WN) in West African Dwarf (WAD) rams, a total mixed ration was formulated with 0 (WN0), 2.5 (WN2.5), 5.0 (WN5), 7.5 (WN7.5), and 10.0 (WN10) % of WN inclusion. Twenty-five yearling rams (12.3 ± 2.0 kg) were assigned to one of the five dietary groups with five animals per group in a completely randomized design. Each group received the diet for 90 days inclusive of the initial 28 days used for anticoccidial efficacy trial. After the growth trial, three rams from each group were used for digestibility and nitrogen metabolism trial. Anticoccidial efficacy linearly increased (P = 0.002) with increased inclusion of WN and duration of feeding (P = 0.003). Feed intake (P = 0.018) and weight gain (P = 0.009) quadratically increased with WN5 inclusion compared to WN10. Optimal inclusion level of WN for daily weight gain was 5.1% (R2 = 0.30). Digestibility of crude protein was linearly and quadratically increased (P = 0.032; P = 0.031, respectively) with up to WN7.5 inclusion. Nitrogen retention was similar among the treatments. Incorporation of water-washed neem fruit in the diets of West African dwarf rams improved nutrient utilization and animal health by increasing anticoccidial efficacy, feed intake, and weight gain. This is an indication that water-washed neem fruit could be used as growth promoter in sheep production.

ABSTRACT

The immergence of antibiotic resistance, in livestock especially poultry, led to the ban of antibiotics as a growth promoter in some part of the world. This brought about the investigations into the development of various alternatives to antibiotics that will not compromise the integrity of poultry products for safe consumption. Therefore, this study examined the possible impacts of selected plants seeds (pawpaw, mustard, and black cumin) as feed additives on the performance, carcass characteristics, and sensory evaluation of broilers. A total of 180 day-old Arbor Acre Plus chicks were randomly assigned to five treatments of four replicates in a completely randomized design. The five treatments were three plant seed additives: pawpaw (PPS), mustard (MUS), and black cumin (BCS), treatment without additives (CON, i.e., no plants seeds/medications), and treatment with medications and antibiotics (ANT). During the feeding trials that lasted for 8 weeks, body weight gain, feed intake, and feed conversion ratio (FCR) were considered performance data. At the end of the feeding trials, two birds per replicate were slaughtered for carcass parameters and sensory evaluation. Data collected were subjected to analysis of variance. Mustard seed (Brassica juncea) significantly (P = 0.018) supported carcass growth. Further, the highest feed intake was obtained in MUS while the lowest was obtained in CON birds. The PPS had higher (P = 0.013) BWG than in other treatments while the lowest was obtained in CON. Values of FCR were lowest (P = 0.15) in PPS while the highest in CON birds. Furthermore, MUS and PPS had significantly (P = 0.018) and (P = 0.03) higher live weight than CON and ANT, while MUS had higher dressed weight percentage than CON and ANT birds. Broiler meat under diet supplemented with black cumin was relatively found to be most acceptable while meat under mustard seed was the least acceptable. In contrast, the average cost realized per bird was obtained in PPS while the lowest was in CON and ANT. However, broiler diet supplemented with BCS brings about a corresponding decrease in percentage feeding cost reduction among plant supplements.

ABSTRACT

The present context was designed to investigate the efficacy of devil fish (DF; Plecostomus sp.) silage and Staphylococcus saprophyticus on fermentation characteristics as well as greenhouse gases production mitigation attributes in horses. Four levels of ensiled DF at 0 (control DF0), 6 (DF6), 12 (DF12), and 18 (DF18) % were added into the diet. Moreover, three doses of S. saprophyticus (0, 1, and 3 mL/g dry matter [DM]) were used for in vitro fecal fermentation. The use of ensiled DF resulted in increased (P < .0001) pH during fermentation. The asymptotic gas production was the highest (P < .0001) in DF6, whereas other supplementation caused lower production than that of control. Lag time for the asymptotic gas production decreased (P < .05) with increasing dietary DF doses. Inclusion of S. saprophyticus resulted in the lowest (P < .05) gas production and mL/0.5 g DM incubated and thus, the reduced gas production up to 23.17% than that of control. The interaction of DF × S. saprophyticus showed the lowest gas production at DF18, whereas the highest production was estimated at DF6 without S. saprophyticus after 48 hours. The lowest emission of CO2 (P < .0001) was observed in DF18 inclusion, which was 15.25% lower than that of control at 48 hours of fermentation. In contrast, the lowest hydrogen (H2) production was estimated in DF0, whereas DF18 exhibited the highest. Inclusion of DF12 and DF18 reduced (P < .05) methane (CH4) emission by 58.24% and 59.33%, respectively. However, DF, S. saprophyticus, and DF × S. saprophyticus interaction had no significant effect (P > .05) on CH4 production. In conclusion, ensiled DF and S. saprophyticus could be supplemented in equine diet as promising alternatives to corn for mitigating the emission of greenhouse gases effectively.

ABSTRACT

Improving digestibility, fermentation characteristics, and reducing greenhouse biogases to protect the environment without the use of synthetic materials is an important goal of modern-day farming and nutritionist. Plant extracts are capable of solving these. This is due to the digestive enzymes and the bioactive components capable of performing antimicrobial functions inherent in these plants. This study was aimed to investigate the effect of standard maize substrate treated with selected herbs and spices extracts on ruminal environmental biogas production and pressure during fermentation via biogas production technique. Herbs (Azadirachta indica leaves (T1), Moringa oleifera leaves (T2), Ocimum gratissimum leaves (T3) and spices (Allium sativum bulb (T4), Zingiber officinale rhizome (T5)) were harvested, air dried, and milled using standard procedures. Methanolic extracts of the herbs and spices were prepared and used as additives at different concentrations (50, 100, and 150 µL) to the maize substrate for in vitro biogas production. Data were analyzed using regression analysis. There were significant (P < 0.05) differences across all the treatments on the volume and pressure of biogas. The pressure and volume of biogas when compared with the levels tested showed differences (P < 0.05) across all the treatments for the prediction of volume from pressure of biogas. The pressure and volume of gas produced in vitro increased (P < 0.05) and biogases decreased (P < 0.05) by the substrate treated with herbs and spices but for the drum stick leaves which was similar for the levels of concentration tested. This means that the level tested had a pronounced mitigation effect on pressure of biogas and volume of biogas produced. It was concluded that the herb and spice extracts have the potential to improve rumen fermentation and reduce the production of biogases in ruminant diet.

ABSTRACT

Several concerns exist regarding horse rearing such as environmental pollution, antibiotics resistance, digestive disorders, mycotoxins contamination of animal feed, gut health management, and improvement of feed efficiency. Nanoparticles have the potential to address these issues and thus could be used as feed additive. Citrate reduces and stabilizes gold nanoparticles, alongside biosynthesized silver nanoparticles have the potential to prolong and improve digestive enzyme activity, which would enhance starch digestibility in the stomach. Zinc oxide and selenium nanoparticles could be used to improve feed digestibility and volatile fatty acids production. Magnesium oxide, silver, and copper nanoparticles exhibit strong antimicrobial activity against gram-positive and gram-negative microbes and weaken the biofilm formation of the microbial community. Calcium, zinc, and silver nanoparticles could be used to prevent periodontal disease in horses. In addition, silver nanoparticles may be applied as antifasciolitics and potentially against other gastrointestinal parasites. Environmental concern of equines could be addressed by using cerium oxide, silver, and cobalt nanoparticles to reduce methane emission and zinc oxide could help to reduce fecal mineral output. Fullerol C60[OH]24, a honey-derived silver nanoparticle and zinc oxide nanoparticles exhibit attractive antibacterial properties because of increased specific surface area as the reduced particle enhance unit surface reactivity. Gut health management of equines could be solved with nanoparticles because of the ability of ferrous oxide and copper nanoparticles to improve microbial growth, whereas zinc oxide improves villus height, crypt depth, and villous surface area. It is required to explore in depth the beneficial effects of these nanoparticles as a novel area in the equine industry's both in vitro and in vivo before recommendation to equine owners.
