Objective: To evaluate the productive variables and digestibility of nutrients an integral diet for lambs with increasing inclusion Samanea saman pods.
 Design/methodology/approach: 24 creole (initial weight 20.6 ± 0.3 kg) distributed in a completely randomized experimental design were used. The treatments were: T1, 0%, T2, 12.5%, T3, 25% pod inclusion. evaluated compared Tukey test (? = 0...

This study was designed to evaluate dry matter intake (DMI), ruminal fermentation, digesta outflow, omasal flow of N constituents, and total-tract digestibility in response increasing dietary lipid content derived from high-lipid by-product-based pellets for finishing beef cattle. Five ruminally cannulated heifers were used a 5 × Latin square design. Dietary treatments iso-nitrogenous with ethe...

Macroalgae has gained increasing interest as antimethanogenic feed additives for cattle, but most in vivo studies are limited to investigating effects of the red macroalgae Asparagopsis spp. Hence, this study aimed investigate CH4 mitigating potential 3 brown from Northern hemisphere when fed dairy cows, and on intake, milk production, digestibility, animal health indicators. The experiment was...

digestibility coefficient of whole cottonseed was determined by in vivo method and total collection feces. the whole cottonseed degradability was determined by nylon bag method. a number of 12 holstein bulls were used in a complete randomized design. the rations contained zero (control), seven, 14 and 21 percentages of whole cottonseed. during the experimental period, daily gain, dry matter int...

Adding sugar to the diet has been reported to improve production in dairy cows. In each of 2 trials, 48 lactating Holsteins (8 with ruminal cannulas) were fed covariate diets for 2 wk, blocked by days in milk into 12 groups of 4, and then randomly assigned to diets based on alfalfa silage containing 4 levels of dried molasses (trial 1) or liquid molasses (trial 2). In both studies, production d...

This experiment was conducted to determine the possibility of replacing part of the barley grain by hydroponic barley fodder (HBF), and evaluating its effect on digestibility, rumen parameters, microbial protein synthesis and blood parameters in sheep. Four male Kermani sheep, 18-month-old (34.7 ± 1 kg live weight) were randomly assigned to a change over 4 × 4 design and fed the experimental di...

In this study, dairy cows were treated with calcium montmorillonite clay (NSP; BASF Corp., Ludwigshaven, Germany) in a replicated 5x5 Latin square design. The primary objectives were to determine if milk composition was altered following ingestion of NSP, and to investigate the ability of NSP to reduce aflatoxin (AF) transfer to milk with the inclusion of low doses in the diet (concentrations e...

Four metabolism and two finishing trials were conducted to determine the effects of imposed feed intake variation on acidosis and performance of finishing steers. In Metabolism Trial 1, four ruminally fistulated steers were limit-fed and subjected to either a constant amount of feed per day (C) or low intake variation of .7 kg/d (LV). No treatment differences were found for intake or measures o...

Since 1992 a number of lactating dairy cows (n 5 247) and beef steers (n 5 75) were offered grass silage-based diets in a range of feeding experiments and subjected to gaseous exchange measurements in calorimetric chambers at the Agricultural Research Institute of Northern Ireland. The objective of the present study was therefore to use the energy metabolism data from these studies to evaluate ...

Twenty growing Small East African goats were used to determine the effects of feeding sun-dried leaves of the browse forages Berchemia discolor and Zizyphus mucronata as supplements to low-quality basal diet, Rhodes grass (Chloris gayana) hay, on voluntary feed intake (VFI), digestibility and growth performance. The grass hay and maize bran were used as a control. The dried leaves were then inc...
