Crambe meal and crude glycerin from biodiesel production in diets for finishing of crossbred cattle in feedlot.

Our hypothesis is that crambe meal can totally substitute soybean meal and crude glycerin can partially replace the corn in the diet without leading to losses of nutrient intake and productive performance. Two assays were performed using heifers and steers. In the first assay, 24 Beefalo-Nellore heifers with 18 months old with 311.5 ± 5.5 kg, and in the second assay, 24 Beefalo-Nellore steers with 18 months old with 317.0 ± 6.4 kg were evaluated. The experiment was carried out in a randomized complete design, in a 2 × 2 factorial scheme, consisting of two energy sources (corn and crude glycerin) and two protein sources (soybean meal and crambe meal). Both assays had 104 experimental days of feedlot. There was no interaction between the variation sources. There was an effect of protein source on nutrient intake for heifers except to neutral detergent fiber intake, which presented effect of energy source. Heifers fed soybean meal showed higher results for total weight gain and daily weight gain. There was observed effect of energy source on rib eye area and subcutaneous fat thickness. Steers fed soybean meal showed higher neutral detergent fiber intake and non-fibrous carbohydrates. Steers fed corn + crude glycerin showed higher results for total weight gain and daily weight gain. The steers fed soybean meal showed higher averages for subcutaneous fat thickness. Crambe meal and crude glycerin can be used as alternative sources of energy and protein to replace 100% of soybean and 50% of corn, respectively, for finishing Beefalo-Nellore cattle in a feedlot.

Lipid rich diet from sunflower seeds can alter the proportion of fatty acids on hybrid Beefalo × Nellore cattle.

We evaluated the lipid level effects in the diet on performance, carcass, and meat characteristics of forty-eight steers and heifers, F1 Beefalo (Bostaurus taurus × Bison bison hybrid) × Nellore (Bos taurus indicus), 22 months old, being 24 steers (393.2 ± 15 kg) and 24 heifers (278.4 ± 8 kg). The animals were distributed in a completely randomized design in a 4 × 2 factorial scheme (lipid levels in diet 55-, 65-, 75-, and 85-g/kg dry matter obtained by whole sunflower grain Helianthus annuus and two sexes). Increased amounts of sunflower grain in diet linearly reduce the proportion of saturated fatty acids (FA) in longissimus thoracis. Diets containing up to 85 g/kg of lipid can be used without negative effects on intake, carcass, and meat quality of Beefalo-Nellore steers and heifers and can be an effective strategy to reduce the proportion of saturated FA and increase unsaturated FA on the meat, which can be beneficial for human consumption.

Autonomic responses of premature newborns to body position and environmental noise in the neonatal intensive care unit. / Respostas autonômicas de recém-nascidos prematuros ao posicionamento do corpo e ruídos ambientais na unidade de terapia intensiva neonatal.

OBJECTIVE: Evaluate the physiological and autonomic nervous system responses of premature newborns to body position and noise in the neonatal intensive care unit. METHODS: A quasi-experimental study. The autonomic nervous system of newborns was evaluated based on heart rate variability when the newborns were exposed to environmental noise and placed in different positions: supine without support, supine with manual restraint and prone. RESULTS: Fifty premature newborns were evaluated (gestational age: 32.6 ± 2.3 weeks; weight: 1816 ± 493g; and Brazelton sleep/awake level: 3 to 4). A positive correlation was found between environmental noise and sympathetic activity (R = 0.27, p = 0.04). The mean environmental noise was 53 ± 14dB. The heart rate was higher in the supine position than in the manual restraint and prone positions (148.7 ± 21.6, 141.9 ± 16 and 144 ± 13, respectively) (p = 0.001). Sympathetic activity, represented by a low frequency index, was higher in the supine position (p < 0.05) than in the other positions, and parasympathetic activity (high frequency, root mean square of the sum of differences between normal adjacent mean R-R interval and percentage of adjacent iRR that differed by more than 50ms) was higher in the prone position (p < 0.05) than in the other positions. The complexity of the autonomic adjustments (approximate entropy and sample entropy) was lower in the supine position than in the other positions. CONCLUSION: The prone position and manual restraint position increased both parasympathetic activity and the complexity of autonomic adjustments in comparison to the supine position, even in the presence of higher environmental noise than the recommended level, which tends to increase sympathetic activity.

OBJETIVO: Avaliar as respostas fisiológicas e do sistema nervoso autônomo de recém-nascidos prematuros ao posicionamento do corpo e ruídos ambientais na unidade de terapia intensiva neonatal. MÉTODOS: Este foi um estudo quasi-experimental. O sistema nervoso autônomo de recém-nascidos foi avaliado com base na variabilidade da frequência cardíaca quando os recém-nascidos foram expostos ao ruído ambiental e colocados em diferentes posições: supina sem suporte, supina com restrição manual e prona. RESULTADOS: Cinquenta recém-nascidos prematuros foram avaliados (idade gestacional de 32,6 ± 2,3 semanas, peso de 1.816 ± 493g e nível Brazelton de sono/vigília de 3 a 4). Identificou-se correlação positiva entre o ruído ambiental e a atividade simpática (R = 0,27; p = 0,04). O ruído ambiental médio foi de 53 ± 14dB. A frequência cardíaca foi mais elevada na posição supina do que nas posições com restrição manual e prona (148,7 ± 21,6; 141,9 ± 16 e 144 ± 13, respectivamente; p = 0,001). A atividade simpática, representada por um índice de baixa frequência, foi mais elevada na posição supina (p < 0,05) do que nas demais posições, e a atividade parassimpática (alta frequência, raiz quadrada da média dos quadrados das diferenças entre os intervalos RR normais adjacentes e porcentagem dos intervalos R-R adjacentes com diferença de duração maior que 50ms) foi mais elevada na posição prona (p < 0,05) do que nas demais posições. A complexidade dos ajustes autonômicos (entropia aproximada e entropia da amostra) foi mais baixa na posição supina do que nas demais posições. CONCLUSÃO: A posição prona e a posição com restrição manual aumentaram tanto a atividade parassimpática quanto a complexidade dos ajustes autonômicos em comparação com a posição supina, mesmo na presença de ruído ambiental maior do que o nível recomendado, o que tende a aumentar a atividade simpática.

Energetic-protein supplementation in the last 60 days of gestation improves performance of beef cows grazing tropical pastures.

BACKGROUND: Nutrition is one of the most important factors that affect animal performance, and it therefore also impacts on financial results in beef systems. In this way, finding the best strategy for feeding supplements is of paramount importance. Aiming to evaluate the effect of supplement feeding strategies for beef cows in the last third of gestation, two experiments were conducted. In Experiment 1, 35 pregnant Nellore cows were assigned to a completely randomized design with four treatments: control, which received no supplement; supplementation for the last 30 d of gestation (30-d; 3.0 kg/d); supplementation for the last 60 d of gestation (60-d; 1.5 kg/d); or supplementation for the last 90 d of gestation (90-d; 1.0 kg/d). All supplemented treatments received the same total amount of supplement throughout the experiment: 90 kg (20% of crude protein). A second experiment (Experiment 2) was delineated to evaluate the effects of the amounts offered in Experiment 1 on intake and metabolism. Four multiparous pregnant Nellore cows were assigned to a 4 × 4 Latin square design, with periods of 15 d each. RESULTS: There was a linear effect of the number of days of supplementation on calving body weight (BW; P < 0.05) and a quadratic effect on BW change from parturition to d 31 post-calving (P < 0.05), with cows on the 60-d strategy losing less BW post-calving. No difference was found in offspring birth BW (P > 0.10). A significant linear effect on interval from parturition to conception (P < 0.05) was observed, with the highest calving to conception interval being observed in the 90-d strategy. The level of supplementation did not affect forage intake or neutral detergent fiber digestibility (P > 0.10). Nitrogen excreted through urine tended to increase linearly with the level of supplementation (P < 0.10). CONCLUSION: Providing 1.5 kg of supplement during the last 60 d of gestation improves cow performance after calving, reducing the magnitude of BW lost, and reduces the number of days from calving to re-conception in the following breeding season compared to the usually recommended period of supplementation of 90 d pre-partum.

Performance, endocrine, metabolic, and reproductive responses of Nellore heifers submitted to different supplementation levels pre- and post-weaning.

The present study was conducted to evaluate the effects of high and low supplementation levels pre- and post-weaning on performance, endocrine, metabolic, and reproductive responses of Nellore heifers. Fifty Nellore heifers with 132 ± 9.9 kg average body weight (BW) and 138 ± 19 days of age were supplemented from 4 to 14 months. The heifers were distributed into five supplementation plans: HH-6 g/kg of BW of supplement pre- and post-weaning, HL-6 g/kg of BW of supplement pre-weaning and 3 g/kg post-weaning, LH-3 g/kg of BW pre-weaning and 6 g/kg of BW post-weaning, LL-3 g/kg of BW pre- and post-weaning, and CC-control, no supplementation. Interactions were not significant (P > 0.10). The level of supplement fed pre-weaning did not affect any of the performance variables evaluated at the end of the experiment (P > 0.10). There was a significant effect of supplementation and level of supplementation fed post-weaning on average daily gain (ADG) and final BW (P < 0.05). Overall ADG was also affected only by supplementation and level of supplement fed post-weaning (P < 0.05) with animals receiving 6 g/kg of BW post-weaning gaining more weight. Follicular diameter was greater in animals that received 6 g/kg of BW post-weaning (P < 0.05). In summary, performance, endocrine, metabolic, and reproductive variables evaluated in the current study were improved by the level of supplement fed post-weaning. Heifers receiving supplementation of 6 g/kg of BW post-weaning had greater responses, independent of the level received during the pre-weaning phase.

Influence of soil cover and N and K fertilization on the quality of biofortified QPM in the humid tropics.

BACKGROUND: In the humid tropics, unfavorable conditions present challenges to smallholder farmers attempting to meet food demands. The objective of this study was to evaluate the influence of alley cropping and addition of potassium and nitrogen on the productivity and nutritional value of quality protein maize (QPM). The experimental design consisted of randomized blocks with four replicates in a 5 × 2 factorial scheme, with five treatments, Gliricidia + Acacia (GA), Gliricidia + Clitoria (GC), Leucaena + Acacia (LA), Leucaena + Clitoria (LC) and bare soil (BS), in two cropping systems, one with addition of nitrogen and potassium (NK) and one without. RESULTS: The grain yield of LC + NK was significantly higher than that of all other treatments except GC + NK and LA + NK, and six times higher than that of BS + NK. The protein content of LC + NK was higher than that of the treatments without residue. CONCLUSION: Although the mulching of tree legumes increased the yield and quality of food for smallholder agriculture, achieving this outcome requires eliminating potentially negative interactions when combining trees and crops in addition to enhancing the availability and uptake of nutrients. © 2015 Society of Chemical Industry.

This article presents the results of a Scientific Initiation Research that investigates the effects of the Harm Reduction approach in reference to the choices and risk perception related to drug abuse and conflicts experienced by adolescents in a vulnerable situation. The research took place at a school in the state of Sao Paulo, based on a methodology of action-research and the theory of Operative Groups. Close to 80 students between the ages of fourteen and sixteen, the pedagogical team, and teachers participated in the research. There were conflictive themes found through analysis of the group's situations, they are as follows: responsibility vs. fun/enjoyment, the adults' lack of reliability towards the adolescents, sex, drugs, respect and stereotypes. The fact that the adolescents were free to express their thoughts made a significant contribution towards our proposals and reflection, enabling greater adhesion. The change of roles, provided for the methodology, contributed to a possible revision of the pre-conceived concepts.

Supplementation of suckling beef calves with different levels of crude protein on tropical pasture.

The effects of supplementation with different levels of crude protein on performance, intake and nutrient digestibility and efficiency of microbial protein synthesis in suckling beef calves on pasture were assessed. Fifty-five calves, with an average age of 100 days and an initial average body weight of 110 ± 7.5 kg and their respective dams, were used. The experimental design was completely randomised with five treatments and 11 replications. The experimental treatments for calves were as follows: control = calves received only mineral mixture; supplementation levels = calves received supplement containing 8, 19, 30 or 41% of crude protein (CP, at a rate of 0.5% of body weight (BW)). The cows received only mineral mixture ad libitum. Supplemented calves had higher (P < 0.1) average daily gain (ADG). Protein levels showed a quadratic effect (P < 0.1) on average daily gain (ADG) of calves. There was no difference in total dry matter (DM) intake (P > 0.1). However, intake of dry matter forage (DMF) presented cubic profiles (P < 0.1), with CP levels in the supplements. Supplementation increased (P < 0.1) the digestibility of nutrients, except for the digestibility of neutral detergent fibre. Supplementation increased (P < 0.1) the production of microbial nitrogen and N losses in urine. It can be concluded that multiple supplementations optimise the performance of beef calves on creep feeding. The intake of supplements with CP levels between 8 and 30% partially replaces of the pasture ingested by calves and increases the digestibility of the diet.

Strategies of supplementation of female suckling calves and nutrition parameters of beef cows on tropical pasture.

The performance of female calves in creep feeding under different strategies of supplementation and milk production, intake, and digestibility of grazing Nellore and crossbred cows (Nellore × Holstein) during the dry-rainy transition season were assessed. Forty-four female beef suckling calves, with initial age between 90 and 150 days and average initial body weight of 117.7 ± 4.3 kg, and their respective dams (24 Nellore and 20 crossbred) with average initial body weight of 417.5 ± 8.3 kg, were used. The experimental treatments consisted of: control group--mineral mixture only; strategy 1--supplementation from 112 days prior to weaning (0.375 kg/animal/day); strategy 2--supplementation from 112 days prior to weaning, in increasing amounts of 0.15, 0.30, 0.45, and 0.60 kg/animal/day through the four experimental periods, respectively; and strategy 3--supplementation from 56 days prior to weaning (0.750 kg/animal/day). Calves from strategy 1 had greater (P < 0.05) average daily gain (0.672 kg/day) than control animals (0.582 kg/day) and greater (P < 0.05) efficiency of supplement use than the other groups. Crossbred cows produced more milk than Nellore cows (P < 0.05). Crossbred cows presented greater (P < 0.05) dry matter intake (DMI) than Nellore cows. However, no differences were found (P > 0.05) for nutrient digestibility among genetic types. It can be concluded that strategies of supplementation that present an equitable distribution of supplement provides greater weight gain in suckling female beef calves. Crossbred cows produce more milk and present greater DMI than Nellore cows. There are no differences in the nutrient digestibility between Nellore and Nellore × Holstein crossbred cows.

Nas amêndoas cruas e torradas não foram encontradas lectinas, taninos, inibidores de tripsina e alfa-amilase. Verificou-se a ausência de peroxidase e polifenoloxidase e conteúdo de compostos fenólicos de 107,7mg/100g e 108,9mg/100g para amêndoas cruas e torradas, respectivamente. CONCLUSÃO: A torrefação realizada a 205ºC por 11 minutos diminuiu o teor de fitatos de 10,6mg/g para 5,5mg/g. Por fim, as amêndoas de chichá, cruas e torradas, apresentam alto teor de proteínas, fibras, ácidos graxos monoinsaturados e saturados.

OBJECTIVE: This study analyzed the chemical components and antinutrients present in raw and roasted chichá almonds from the species Sterculia striata A. St. Hill & Naudin harvested in Corrente, Piauí. METHODS: The following were determined: percent composition, fatty acid profile, antinutrients (tannins, trypsin inhibitor, amylase inhibitor, lectin, phytates), phenolic compounds and peroxidase and polyphenol oxidase activities. RESULTS: The percentage composition of the raw and lipid almonds were respectively: 25.1 percent and 26.2 percent fats, 44.4 percent and 45.6 percent carbohydrates, 20.8 percent and 22.1 percent protein, 3.7 percent and 4.0 percent ashes, and 12.3 percent and 10.4 percent total fiber. Neither raw nor roasted almonds contained lectins, tannins, trypsin inhibitors, alpha-amylase, peroxidase and polyphenol oxidase. Contents of phenolic compounds were 107.7mg/100g and 108.9mg/100 for the raw and roasted almonds, respectively. CONCLUSION: Roasting at 205ºC for 11 minutes reduced phytate content from 10.6mg/g to 5.5mg/g. Raw and roasted chichá almonds have a high content of proteins, fibers and monounsaturated and saturated fatty acids.

Análise física, sensorial e microbiológica de geléias de manga formuladas com diferentes níveis de cascas em substituição à polpa / Physical, sensory and microbiological analysis of mango jams formulated with different levels of peels in substitution to pulp

O objetivo deste estudo foi avaliar a qualidade de geléias formuladas com níveis de zero, 25, 50, 75 e 100 por cento de casca em substituição à polpa de manga (Mangifera indica L. cv. "Haden"). Os critérios de qualidade utilizados foram: a cor, a consistência, a aceitabilidade sensorial (aparência, aroma e sabor) e as características microbiológicas dos diferentes tratamentos. Observou-se que todos os tratamentos obtiveram, por meio de análise consumidores, escores médios entre sete (gostei moderadamente) e oito (gostei muito). As características físicas e microbiológicas mantiveram-se dentro dos padrões de geléias de frutas estabelecidos pela legislação brasileira. Pelos resultados obtidos, a substituição parcial ou total da polpa por cascas na formulação de geléia de manga Haden é uma alternativa viável nas áreas física, sensorial e microbiológica, com benefícios econômicos e ambientais.

The objective of this study was to evaluate the quality of jams formulated with levels of zero, 25, 50, 75 and 100 percent of peels in substitution of pulp of mango (Mangifera indica L. cv. 'Haden'). The quality criterion were color, consistency, sensory acceptability and microbiological characteristics. It was observed that all treatments obtained with the consumers mean scores between seven (liked moderated) and eight (liked a lot). Physical and microbiological characteristics were maintained inside of the fruit jams patterns established for Brazilian legislation. For the gotten results, the partial or total substitution of pulp for peels Haden mango in the jams formulation is viable on the physical, sensory and microbiological areas, with economic and environmental advantages.

A influência da atividade física na saúde e qualidade de vida dos idosos

Este estudo teve como objetivo elaborar um plano de ação para estimular a prática de atividade física e hábitos saudáveis de vida nos idosos da área de abrangência da Unidade Básica de Saúde de Santa Clara. No diagnóstico situacional observou-se um elevado número de idosos sedentários. Baseando-se neste problema foram selecionados os seguintes nós críticos: falta de informações entre os idosos, falta de preocupação das famílias e falta de oportunidade e opções de lazer. Para enfrentar esses nós críticos e estimular a prática de atividade física entre os idosos foram estabelecidas diferentes ações de intervenção: atividades teóricas educativas e atividades práticas.
