the effect of the substitution of imported raw materials (corn and soyabeans) by local food resources (barley, white sorghum, triticale and horse bean) on the parameters of faciesfermentation and digestibility in the rumen of sheep was evaluated. four sicilo-sarde rams 4.8±0.5 years of age with an average live weight of 45.25±3.5 kg, permanently canulated in the rumen and housed in individual c...

Two experiments were conducted to determine the amino acid (AA) digestibility and nitrogen (N) utilization of three maize hybrids, i.e. high oil (HO), waxy (WX), and high lysine (HL) as compared to isogenic high oil (IHO), isogenic waxy (IWX), and a yellow dent (YD1) maize variety near-isogenic to HL. One yellow dent maize of unrelated genetics (YD2) was included as an additional control and to...

The effect of the substitution of imported raw materials (corn and soyabeans) by local food resources (barley, white sorghum, triticale and horse bean) on the parameters of faciesfermentation and digestibility in the rumen of sheep was evaluated. Four Sicilo-Sarde rams 4.8±0.5 years of age with an average live weight of 45.25±3.5 kg, permanently canulated in the rumen and housed in individual c...

The objective of this experiment was to evaluate the effect of providing different levels of a supplement on the nutritional characteristics and productive performance of heifers on pasture during the rainy-dry transition and dry season in Brazil or tropical area. Thirty crossbred heifers with predominance of Zebu breed were used in a completely randomized experimental design. Treatments consis...

Eight mature dogs (19.3 +/- 0.1 kg) were used in an experiment to compare the effects of feeding soybeans containing low concentrations of oligosaccharides and phytate on nutrient availability in complete foods fed to dogs. All foods were formulated to be isonitrogenous and contained low-oligosaccharide, low-phytate soybean meal (LLM); conventional soybean meal (SBM); low-oligosaccharide, low-p...

The study was conducted to compare the effects of feeding Acacia auriculata (AA), Gmelina arborea (GA), Albizia lebbeck (AL) and Butryospermum parkii (BP) tree forages as a sole feed for Nigerian goats. Four goats (Yankasa) averaging one year and weighing 11.7±1.8 kg were used to measure the feed intake, digestibility and nitrogen balance. The leaves were offered ad libitum. Dry matter (DM) int...

The aim of the present experiment was to examine the effect of coccidia challenge and natural betaine supplementation on performance, nutrient utilization, and intestinal lesion scores of broiler chickens fed suboptimal level of dietary methionine. The experimental design was a 2×2 factorial arrangement of treatments evaluating two levels of betaine supplementation (0 and 960 g betaine/t of fee...

deal effectively with the increased density of the pork industry in some areas and the increased public concerns regarding nutrient excretion and odour emissions. Successful management of nitrogen and phosphorus is key for sustainable pork production to address these public concerns. For example, nitrogen excretion in the form of ammonia is a concern because of its impact on the work environmen...

The remnants of pesticides in livestock feeds have been increased by excessive using of these pesticides so as to meet extreme demands for more feeds. Finding a new strategy for reducing pesticides negative effects is absolutely necessary. Therefore, evaluation of the effects of sodium bentonite on blood parameters, feed digestibility and rumen fermentation parameters in sheep fed diets contami...

Twenty-four cecectomized and 24 intact White Pekin ducks were used in two experiments to assess the influence of cecectomy on ME and amino acid digestibility of several feed ingredients for ducks. Corn and soybean meal (SBM) were evaluated in Experiment 1, and bakery meal (BM), red dog (RD), and wheat middlings (WM) were evaluated in Experiment 2. Nitrogen-corrected true metabolizable energy an...
