Four ruminally cannulated Holstein heifers (287 +/- 26 kg) in a 4 x 4 Latin square were used to evaluate the effects of naloxone injection and forage level on dietary intake, ruminal fermentation characteristics, digestibility, and plasma hormone and metabolite concentrations. Treatments were arranged in a 2 x 2 factorial with naloxone injection (0 vs .3 mg/kg; saline vs naloxone, respectively)...

Feed additives are largely used in beef cattle diets to improve performance and reduce risks of nutritional disorder diseases like acidosis and timpanism. However, some countries tend to ban the use of ionophore in animal nutrition due to the risk of resistance of some microorganisms. Therefore, alternatives to non-antibiotic additives must be studied. The objective of this work was to investig...

Over 2 yr, a total of 96 steers (approximately 7 mo of age) were allocated to 1 of 4 weaning management strategies: 1) control: weaned on the day of shipping; 2) creep-fed: allowed free-choice access to concentrate before weaning and shipping; 3) preweaned: weaned and provided supplemental concentrate on pasture before shipping; and 4) early-weaned: weaned at 70 to 90 d of age and kept on pastu...

a 90 day study was conducted on twenty four indigenous non-descript goats allocated into four groups. they were fed ad libitum basal complete feed constituted rice straw: rhea (60:40) grass hay and concentrate mixture @ 250/animal/day. basal complete feed contain 11.07% dcp and 54.21% tdn. groups were control (t0) basal diet without polyherbal supplementation, treatment 1 (t1) diet with ruchama...

Feed deprivation is commonly used by the poultry industry to induce molting and stimulate multiple egg-laying cycles. However, feed deprivation has been observed experimentally to increase susceptibility of poultry to Salmonella infections. Previous studies indicated that alfalfa was efficacious in reducing Salmonella; the present investigation was designed to evaluate the efficacy of combined ...

A total of 487samples (77 and 410 of poultry feed ingredients and poultry feed, respectively) received from various parts of the country were analysed for detection of Aflatoxin B1 (AFB1). Overall incidence of AFB1 in feed ingredients was 60 percent. The average contamination and maximum levels of AFB1 were 37.62 and 56 g/kg, respectively, whereas, the incidence in poultry feed samples was 44....

total protein intake. The estimated percentage of ruminal bypass of feed protein was only slightly higher in cows fed extra-heat SBM compared to the control group (28.8 vs 27.8 percent). Therefore, based on these data and those in the feeding trial, it appeared that the extra-heat SBM (PDl-IO) used in this trial was not heated extensively enough during processing to make it a high bypass feed p...

The article studied the dependence of productive qualities and feed cost on growth pigs during rearing fattening with partial (50 %) complete (100 replacement soybean meal high-protein protein concentrate “Proglot” in diet. It was established that use sunflower piglets led to a decrease growing intensity by 0.87 % 4.95 total replacement. And as result live weight 0.3 at end period 1.2 products ...

Pelletizing plant of the Gol-E-Gohar mining and industrial company consists of a burner, a dry ball mill (6.2 m × 13 m), and an air separator. The ball mill consists of a 2 m-long drying and an 11 m-long grinding chambers. The iron ore concentrate is fed to the drying chamber by a feed chute. It was found that when the feed moisture content increased from 1.3% to 3.5%, the throughput decreased ...
