Reducing Dietary Crude Protein: Characterization of Branched-Chain Amino Acid Antagonism in Modern Broiler Chickens
<p>Reducing the crude protein content of broiler diets while maintaining performance has been a primary research area in nutrition. During the late 20th century, the bulk of this research has involved supplementing broiler diets with feed-grade amino acids and proving the economic benefits of their …

The interaction between dietary crude protein and amino acid levels in weaner pigs in an antibiotic-free environment with or without Bacillus amyloliquefaciens supplementation
The interaction between dietary crude protein and amino acid levels in weaner pigs in an antibiotic-free environment with or without Bacillus amyloliquefaciens supplementation Natasha van Niekerk High crude protein (CP) diets cause a myriad of digestive problems in weaner pigs due to incomplete …

Dietary crude protein and nitrogen utilisation in two contrasting dairy systems : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Animal Science, School of Agriculture and Environment, Massey University, Palmerston North, New Zealand
This thesis evaluated the efficiency of crude protein utilisation (ECPU) in dairy cows and nitrogen (N) utilisation efficiency (NUE) of two pasture-based dairy systems differing in intensification levels in New Zealand. During two consecutive seasons, in the low-intensity production system (LIPS), …

The Husbandry and Nutrition of Carp Larvae and Fry
… and food conversion. It was postulated that a dietary crude protein content of 45% was optimal for carp fry of 100–500 mg live body weight, and that inclusion of lipid at levels above 5% of the dry diet did not appear to offer any advantages in terms of growth. Manufacture of water-stable diets …

Effects of Supplementing Crystalline L-Valine and L-Isoleucine and a Novel Threonine Biomass in Reduced Crude Protein Diets fed to Broilers
… well-being. A common approach is to reduce dietary crude protein (CP), the second most expensive component in a broiler diet. Subsequently, reducing CP will reduce the inclusion levels of intact protein sources (e.g., soybean meal [SBM]), which can be accomplished by supplementing individual …

Technologies to Reduce Nutrient Excretion and Odor Production in Swine
The use of low protein and a new phytase enzyme were studied in swine diets, as nutritional strategies to improve the efficiency in the use of nitrogen and phosphorus, and also to reduce NH3 production and odor offensiveness from pig production, while producing environmentally friendly manure. The …

Nitrogen balance and nutrient requirements of young Nellore bulls fed with static or oscillating crude protein levels, and feeding behavior, water intake and requirements of bulls with different residual feed intakes
… this study were 1) to evaluate the effects of dietary crude protein (CP) supply on intake, digestibility, performance, N balance, and requirements of young Nellore bulls, and 2) to determine feeding behavior, water intake, and requirements of high and low residual feed intake (RFI) Nellore …

Fetal programming in cattle: the effects of varying maternal protein intake in adolescent beef heifers on fetal and postnatal growth and development of the calf
… systems. In the northern Australian rangelands, protein, rather than energy, is the major limiting nutrient for cattle in dry-season pastures with protein supplementation of breeding heifers an animal husbandry requirement. Few studies in cattle have specifically evaluated the effects of maternal …

Impact of dietary modification on aflatoxicosis in poultry
… of aflatoxicosis and its interrelationships with dietary modifications in broiler chicks and ducks. Results of these studies emphasize the many factors that the severity of aflatoxicosis depends on, including animal species, age, presence of mycotoxin adsorbent, and concentration of major dietary …

Reducing crude protein levels in diets fed to young pigs to optimize growth performance and intestinal health
… to evaluate the effects of reducing the dietary crude protein (CP) concentration in diets fed to weanling pigs on growth performance, post-weaning diarrhea (PWD), blood characteristics, gut morphology, and products of protein fermentation. Both experiments used the same formulation of 3 …
