Intake prediction equations were developed from a commercial feedlot database consisting of 3,363 pen means collected from 3 feedlots over a 4-yr period. The objective was to predict feeding-period average DMI from variables known at the start of the feeding period, including initial BW, sex, and average DMI from d 8 to 28 of the feeding period. Equations were evaluated within the same database...

The present study was designed to determine the adverse effect of sodium benzoate (SB), vitamin C (Vit.C) alone and their combination on liver kidney functions in rabbits. Thirty-six adult male rabbits were divided randomly into six equal groups. Group 1 (Control group) received orally distal water, group 2: Vit.C (200mg/kg BW/day) orally, 3: SB (60 mg/kg BW/day), 4: (120 BW/day). 5: SB+Vit.C (...

this study was conducted to investigate the effects of age and sex on the fleece characteristics of 40 iranian indigenous khorasan goats. goats were divided into two different sex and age (kids and adults) groups. fiber characteristics under study were: fleece weight, fiber length, lock length, fiber diameter, coefficient of fiber diameter, breaking load, resistance, elongation, hair percentage...

Two experiments were conducted to determine the effects of rancidity and FFA in choice white grease (CWG) on growth performance and nutrient digestibility in nursery pigs. In Exp. 1,150 crossbred pigs (average initial BW of 6.8 kg and average initial age of 21 d) were used. Treatments (as-fed basis) were a corn-soybean meal-based control with no added fat, 6% CWG, and 6% CWG heated at 80 degree...

This study was conducted to investigate the effects of xylanase (XYL) and xylo-oligosaccharide (XOS) supplementation on growth performance faecal bacterial community composition in growing pigs over time. In this 35-day trial, a total 464 grower with an average initial body weight (BW) 14.5 kg (SD ±1.56 kg) were blocked into mixed sexed pens 4–5 balanced for BW, sex litter origin. Pens randomly...

Acrylamide is a substance occured carbohydrate-rich foods during cooking high temperature and because of its small and hydrophilic structure, it can diffuses easily throughout the body. Due to this reason all tissues teorically become the target according to the acrylamide toxicity. In this study it was investigated whether acrylamide has any effect on the renal function of the male and female ...

Two trials were initiated to determine if slaframine (SF) can be used to alter fluid digesta flow and fermentation patterns in the rumen. In trial 1, a preliminary experiment, four Dorset X Barbados Black-belly ruminal-cannulated wethers (avg weight 41.6 8.7 kg) given ad libitum access to a pelleted concentrate/hay diet were injected intramuscularly with 0, 12, 24 or 48 micrograms SF/kg body we...

Three experiments were conducted to study the effects of lasalocid level on performance, intake, digestibility, ruminal fermentation and fluid flow of beef cattle grazing dormant, tallgrass prairie. In Exp. 1, 120 pregnant, mature beef cows of primarily Hereford breeding (avg wt = 471 kg) were randomly assigned to received 0, 100, 200 or 300 mg lasalocid X head-1 X d-1 in 1.82 kg supplement. We...
