in order to investigate the effect of processing type (whole straw bale processing or opened straw bale processing with urea) on diet digestibility, economical and productive parameters in feedlot cattle, 18 holstein bull with average body weight 224.72 ± 20.45 kg were used in a completely randomized design with 3 treatments and 6 replicate. treatments 1, 2 and 3 contained 40% typical straw, 40...

an 84-day feeding trial was carried out onfingerling (4.44 ± 0.06 g) rainbow trout (oncorhynchusmykiss, walbaum, 1792) to evaluate the effect of dietary supplementation with a commercial prebiotic grobiotic®-a (g-a) on the growth, feed efficiency, haematology and immunlogical parameters. ttreatments containing various inclusions of g-a (0 %, 0.5 %, 1.0 %, 1.5 %, 2.0 %, 2.5 %, and 3.0 %) were ad...

in this study, genetic parameters and (co)variance components were estimated for weights at birth, 3, 6, 9, 12, 24 months, daily weight gain from birth to 3 months and daily weight gain from 3 month to 12 month, keliber ratio from birth to 3 months and keliber ratio from 3 to 12 month, and production of fleece for south khorasan goats at sarbisheh station over a period of 16 years (1996–2012). ...

The influence of additive and nonadditive genetic effects and temperament on 4 postweaning feed intake and growth traits was evaluated in a group of 581 bull, heifer, and steer calves born in 3 Florida herds in 2006 and 2007. Calves had breed compositions ranging from 100% Angus (A) to 100% Brahman (B). They were randomly allocated to 24 pens each year by herd (Brooksville, Gainesville, Mariann...

Abstract Unhealthy snacking is considered one of the main contributors to current obesity pandemic. Initial research suggests that work-related stress may be an important predictor unhealthy snacking, however, there still much learn about underlying mechanisms and conditions snacking. To address this gap, we investigated effect two prominent work stressors, workload interpersonal conflict, on b...

Fourteen trials were conducted to evaluate the effects of feeding monensin at 33 ppm alone, tylosin at 11 ppm alone and the two feed additives in combination on the average daily gain, average daily feed intake, feed:gain ratio and the incidence of liver abscesses in feedlot cattle. Monensin reduced feed intake and improved feed efficiency (P less than .05), and had no effect on average daily g...

The present study was performed to study the effect of inbreeding on the pre-weaning growth traits including the birth weight (BW), weaning weight (WW), average daily gain (ADG), Kleiber ratio (KR) and lamb survival from birth to weaning (SUR) in Baluchi, Iran-Black and Zandi sheep. Significant positive inbreeding trends were found only for Baluchi and Iran-Black breeds as 0.038 and 0.278, resp...
