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...

This study was performed with growing chicken (14 to 56 d of age) to evaluate the effects of feeding them a barley or triticale-based diet. The treatments were corn diet (1) as a control, hulless barley diet with (5) or without (2) enzyme, triticale diet with (6) or without (3) enzyme and hulled barley diet with (7) or without (4) a commercial β-glucanase enzyme. In a digestibility trial, 21 ma...

The aim of the present study was to evaluate the effects of canola bioactive peptides (CBP) produced by enzymatic hydrolysis of canola meal on performance, digestive enzyme activity, nutrient digestibility, gut microflora and intestinal morphology of broiler chickens. A total of 250 one-day-old Ross 308 male broiler chicks were randomly allocated to 5 dietary treatments with 5 replicates of 10 ...

Organic acids have been supplemented to weanling pig diets in an attempt to improve postweaning lag. Organic acids have proved beneficial in improving average daily gain (ADG) and increasing nutrient digestibility (Falkowski and Aherne, 1984; Edmonds et al., 1985; Geisting and Easter, 1985). There has also been interest in acidifying grower pig diets in an attempt to increase ADG and improve fe...

The objective of this study was to compare the effects of soybean (SB) meal (SBM) with increased rumen undegradable protein as roasted SB (RSB), extruded SB (ESB) or their equal blend (RSB + ESB) on production performance, nutrient digestibility, N-utilization efficiency, and blood metabolites in mid-lactation dairy cows. Eight lactating Holstein cows (BW = 534 ± 52 and DIM = 104 ± 5; mean ± SD...

A sheep digestion trial and two feedlot trials with cattle were conducted to study effects of an ionophore, salinomycin, on nutrient digestibility, ruminal metabolism and cattle performance. In trial 1, addition of salinomycin at 5.5, 11 or 22 ppm to 60% concentrate diets fed to ruminal-cannulated rams had no effect (P greater than .05) on apparent digestibility of dry matter (DM), organic matt...

AIM This study was planned to investigate the effect of feeding different levels of chayote (Sechium edule) meal by replacing standard concentrate mixture (CM) on the growth parameters such as feed intake, body weight gain, average daily gain (ADG) and feed conversion ratio (FCR), and nutrient utilization in indigenous pig of Mizoram. MATERIALS AND METHODS Twenty-four growing indigenous pigs ...
