Effect of balancing low protein diets for methionine and lysine on performance of early lactation Holstein cows in hot environmental temperature
The aim of this study was to evaluate the effects of balancing low protein diets for methionine and lysine on performance of early lactation Holstein cows under hot environmental temperature. Twenty one multiparous Holstein cows in early lactation were allocated to three experimental rations including, 1) High protein ration with 17.5% CP, 2) Medium protein ration with 16% CP and 12 g/d rumen p...
متن کاملComparative composition, diversity, and abundance of oligosaccharides in early lactation milk from commercial dairy and beef cows
Prebiotics are nondigestible dietary ingredients, usually oligosaccharides (OS), that provide a health benefit to the host by directly modulating the gut microbiota. Although there is some information describing OS content in dairy-source milk, no information is available to describe the OS content of beef-source milk. Given the different trait emphasis between dairy and beef for milk productio...
متن کاملThe response of highly productive rabbits to dietary sulphur amino acid content for reproduction and growth.
This study investigated the sulphur amino acid (SAA) requirements of rabbits. Five diets, containing 0.48-0.72% crude SAA, were formulated by supplementing a basal diet with DL-methionine. The apparent methionine digestibility (%) was 71.4 +/- 1.1 in the basal diet and 102.9 +/- 0.9 for DL-methionine, as estimated by the difference method. Feeding trials were carried out using 370 rabbit does a...
متن کاملEffects of Supplementing Xylose‐Treated Soybean Meal or Untreated Corn Gluten Meal to Lactating Dairy Cows
This experiment was performed to investigate whether feeding xylose-treated soybean meal (XSBM) or corn gluten meal (CGM) is economically better under field conditions. Ninety-four multiparous early lactating Holstein cows (55±5 days in milk and 2.82±0.41 body condition score) were used in a completely randomized design. Cows were randomly assigned to one of two treatments: XSBM or CGM as the m...
متن کاملGenetics and genomics of reproductive performance in dairy and beef cattle.
Excellent reproductive performance in both males and females is fundamental to profitable dairy and beef production systems. In this review we undertook a meta-analysis of genetic parameters for female reproductive performance across 55 dairy studies or populations and 12 beef studies or populations as well as across 28 different studies or populations for male reproductive performance. A pleth...
