Introduction The management of gastrointestinal (GI) problems in livestock and companion animals presents medical and economic challenges. In cattle, neonatal calf diarrhea is recognized worldwide as one of the greatest challenges for both the beef and dairy industries (1, 2). Approximately one-third of U.S. beef cow-calf owners agree that it has an economic impact on their operations (3). Acco...

The objective of these two feeding trials was to determine the associative effects of feeding steam-flaked grain sorghum (SFGS) in combination with steam-flaked (SFC), dry-rolled (DRC), or high-moisture (HMC) corn on growth performance and carcass characteristics in feedlot cattle. In Trial 1, 200 yearling heifers were blocked by weight, allotted to 25 pens, and fed one of five finishing diets ...

Live weight and ultrasound measures of fat thickness and longissimus muscle area were available on 404 yearling bulls and 514 heifers, and carcass measures of weight, longissimus muscle area, and fat thickness were available on 235 steers. Breeding values were initially estimated for carcass weight, longissimus muscle area, and fat thickness using only steer carcass data. Breeding values were a...

Two experiments evaluated different levels of sorghum wet distiller’s grains plus solubles (SWDG) and effects of increasing the degraded intake protein (DIP) concentration in diets containing SWDG on performance and carcass characteristics of feedlot cattle. In Exp. 1, 200 beef steers (average BW = 404 kg) were fed increasing levels of SWDG (0, 5, 10, and 15% of DM) and one level of corn wet di...

________________________________________________________________________________ Abstract The effect of sex and the supplementation of the prebiotic, mannan oligosaccharides (MOS), the acidifier, calcium propionate (CPr) or their combination in the feed of Japanese quail (Coturnix japonica) on their performance and carcass quality was examined in this experimentation. Three hundred, 1-day old J...

the effect of genotype, sex and hatch on carcass traits and physical characteristics of eggs was investigated in the japanese quail. two strains of japanese quails including the white (p1) and wild (p2) genotypes were chosen as the parental generation and crossed reciprocally (10 single-pair mating) to create the f1 progeny. the f1 birds (27 males and 81 females) were mated randomly to produce ...

Quality carcass and non-carcass are two inseparable components that result from slaughtering animals with high economic value. The aims study is effect of polimorfisme DGAT1 gene on hot cold carcass, neck traits in Indonesia sheep. A total 50 rams used this were collected 10 Barbados Cross Sheep (BCS), Compass Agrinac (CAS), 15 Javanese Thin-Tailed (JTTS), Jonggol (JS). sheep slaughtered at 10-...

Mature cows (146) representing Angus, Braunvieh, Charolais, Gelbvieh, Hereford, Limousin, Pinzgauer, Red Poll, and Simmental breeds were slaughtered to contribute to the investigation of the effect of various feed availabilities on body composition. Weights recorded when cows were placed on feed were used to set daily diets at four rates of intake within each breed (55, 76, 96, and 111 g DM/[kg...

Crossbreeding of Holstein–Friesian dairy cows with both early maturing (e.g. Aberdeen Angus (AA)) and late maturing (e.g. Belgian Blue (BB)) beef breeds is commonly practised. In Ireland, genetic merit for growth rate of beef sires is expressed as expected progeny difference for carcass weight (EPDCWT). The objective of this study was to compare the progeny of Holstein–Friesian cows, sired by A...
