RESUMO
OBJECTIVE: One hundred hybrid male ducks (Mojosari×Alabio) were used to examine the efficacy of chicory supplementation as nutritional feed manipulation on production performance, and blood lipid profile of hybrid ducks. METHODS: The ducks were tagged, weighed, and then allotted randomly to one of the four treatment diets using a completely randomized design. The experimental diets were: i) P0 (100% basal diets+0% chicory as control), ii) P1 (95% basal diets+5% chicory), iii) P2 (90% basal diets+10% chicory) and iv) P3 (85% basal diets+15% chicory). For each treatment group, there were 5 replicates of 5 birds each. All experimental diets were isonitrogenous and isocaloric using locally available ingredients. RESULTS: Hybrid ducks with fed diets supplemented fresh chicory (5%, 10%, and 15%) showed increased feed intake and body weight gain, as well as feed conversion ratio to be smaller than those ducks fed diets without chicory supplementation (control). The ducks fed 10% chicory supplementation contained significantly (p<0.05) lower ash and higher organic matter contents of meat than those ducks fed other diets. The ducks fed 15% chicory supplementation showed the lowest crude protein and cholesterol content of meat among the treatment diets. Ducks fed chicory supplementation showed lower (p<0.05) blood cholesterol and triglyceride levels than those ducks fed without chicory supplementation, while dietary interventions had no major (p>0.05) influence on low-density lipoprotein and high-density lipoprotein levels in duck blood. CONCLUSION: In this study, 10% chicory supplementation showed the best results characterized by an increase in growth performance, carcass quality, small intestinal histomorphology, and lower cholesterol levels of meat.
RESUMO
Objectives: The goal of this research was to figure out the effect of the local sorghum as silage on the performance of Bligon goats. Microbial protein synthesis, digestible nutrients, and average daily weight gain (ADWG) were measured to evaluate the goats' performance. Materials and Methods: The study was designed in a completely randomized design with a one-way pattern. Twelve female Bligon goats with 24.33 ± 2.83 kg (mean ± SEM) initial body weight were divided into three groups of total mixed ration (TMR) treatments. Group 1 received fresh Napier grass (FNG) as a control, group 2 received imported sorghum silage (ISS) of brown midrib resistance (BMR), and group 3 received local sorghum silage (LSS) of super-2. Analysis of variance was used to analyze the data on microbial protein synthesis and feed intake during the research. On the contrary, analysis of covariance was used to analyze ADWG with initial weight as a covariate. Results: Microbial protein synthesis, feed-intake, and ADWG of goats that received TMR based on silage of two varieties of sorghum, namely BMR (ISS) and super-2 (LSS), were lower (p < 0.05) than control. However, there was no significant difference between both TMR based on sorghum silages. ISS's feed conversion was better than LSS (p < 0.05), and FNG was the best. Sorghum silage as a basal ration in TMR had lower microbial protein synthesis but higher total digestible nutrient content than fresh forage, such as Napier grass. The sorghum varieties did not affect the microbial protein synthesis, digestible nutrients, and ADWG of Bligon goats. However, ISS treatment had higher feed efficiency than LSS. Conclusion: The local sorghum (super-2) silage can be used as ruminant feed as well as imported sorghum (BMR) offered as TMR. However, regardless of the cultivar, TMR based on sorghum silage cannot replace TMR based on fresh Napier grass.
