Optimizing gut health has a large impact on nutrient digestibility and bioavailability, and super-dosing feed enzymes may be one solution to achieve this. A 42-day grow-out trial was conducted using 192 Ross 308 broilers to determine if super-dosing Natuzyme at 0 g/t, 350 g/t, 700 g/t, and 1000 g/t dose rates could improve the gut morphology, alter...
Article
Full-text available
SUMMERY Valine is the fourth-limiting amino acid in corn-soybean meal-based diets for broilers, and any deficiency of this amino acid (AA) in diet would result in impaired growth performance. As feed-grade Val became commercially available, the focus is now on satisfying the needs of this AA in broiler diets. The purpose of this study was, therefor...

This experiment was conducted to evaluate the effects of dietary supplementation of whey powder (WP), Bacillus subtilis (BAS), and their combination (MIX) on growth performance, intestinal morphology, caecal microflora, hepatic gene expression, blood metabolites, and skeletal muscle antioxidant capacity in Japanese quails. A total of 400 one‐day‐ol...
Article
A biological assay was carried out to evaluate the impact of dietary tryptophan (TRP) in aflatoxin B1‐contaminated diets (AFB1‐D) on performance, blood parameters, immunity, meat quality and microbial populations of intestine in Japanese quails. Six experimental diets were formulated to include two levels of dietary TRP; 2.9 (moderate high: MH‐TRP)...

A dose-response study into increasing level of dietary protein to energy content during the rearing phase of broiler breeder production was conducted. Nine hundred and sixty ROSS 308 day-old breeder chicks were assigned to 1 of 6 dietary treatments including-20,-15,-10,-5, 0, and +5% of the recommended CP levels during rearing. Each experimental di...
Presentation
Full-text available
Current requirements of the branched chain amino acids (BCAA) isoleucine (Ile), leucine (Leu), and valine (Val) have been estimated empirically in dose-response experiments using pig growth as the response criteria. The metabolic response to the optimum dietary BCAA levels may be an alternative to animal growth as the response criteria, and would u...
Article
Traditional AA dose-response studies utilize many animals for evaluation of growth performance, and it is hypothesized that a new experimental design based on modern analytical techniques can reduce the number of used animals. The objective was to evaluate a short-term approach with a low number of pigs based on plasma metabolites as a method to de...
Article
The metabolic response to plasma and urine of pigs when feeding an optimum level of BCAA for best growth performance is unknown. The objective of the current study was to identify the metabolic phenotype associated with the BCAA intake level that could be linked to the animal growth performance. Three dose-response studies were carried out to colle...
Book
The objective was to evaluate a short-term approach with a low number of pigs based on blood samples as a method to determine the requirement for Ile, Leu, and Val. Three independent 6x6 Latin square experiments with six diets containing incrcasing concentrations of Ile, Leu or Val fed to six 8-9 kg pigs for two d each were conducted during a perio...
Book
The objective of the current study was to identify biomarkers of branched chain amino acids (BCAA) intake status that could be linked to the best animal growth perfonnance. Three dose-response studics were carried out to collect blood and urine samples from pigs fed diets with increasing levels of isoleucine (Ile), valine (Val), or leucine (Leu) fo...
Conference Paper
Full-text available
A complete investigation from day-old broiler breeder chick to the corresponding offspring grow out was conducted at the Cargill Animal Nutrition innovation center to address 2 research questions: 1) does growth pattern of breeder pullets during rearing affect breeder and offspring performance and 2) can reduction of dietary crude protein (CP) duri...

The objective was to determine the concentration of L-Trp and L-Val to be substituted by feeding piglets Bacillus subtilis strains developed to overproduce Trp (B. subtilis Trp mutant [BsTrp]) and Val (B. subtilis Val mutant [BsVal]) and by using equations obtained in 3 dose–response studies with Leu, Trp, and Val. A Leu-deficient diet with BsVal w...

Mutants of Bacillus subtilis can be developed to overproduce Val in vitro . It was hypothesized that addition of Bacillus subtilis mutants to pig diets can be a strategy to supply the animal with Val. The objective was to investigate the effect of Bacillus subtilis mutants on growth performance and blood amino acid (AA) concentrations when fed to p...

Abstract Natural dietary antioxidants are important for their ability to protect cells from miscellaneous damage. Grape seed (GS) (Vitis vinifera L., Vitacease) is a potent natural antioxidant. The present study aimed to investigate the protective effect of GS against the possible testicular dysfunction caused by Lindane in male rabbits. Eighty sex...

The objective was to define the Val requirement for weaned piglets in the context of reducing the dietary protein content. A dose-response experiment was conducted to estimate the standardized ileal digestible (SID) Val to Lys ratio required to support the optimum growth of post-weaned piglets. In this study, 96 pigs weighing 8 kg were allotted to...
Article
The objective of the study was to estimate Leu requirement for weaned piglets to balance indispensable AA in reduced CP diets. A dose-response experiment was conducted to estimate the standardized ileal digestible (SID) Leu to Lys ratio required for the maximum growth of young pigs after weaning. In this study, 96 female pigs (initial BW of 8 kg) w...

Article
The objective of the present study was to evaluate the optimum ratio of standardized ileal digestible (SID) Trp to Lys for pigs after weaning. A total of 96 female pigs were allocated to 1 of 6 diets containing 0.13, 0.15, 0.17, 0.19, 0.21, and 0.23 SID Trp:Lys, with 16 individually housed pigs/treatment. The diets contained similar crude protein (...
Article
This study aimed at refining the response of piglets to different supplies of standardized ileal digestible (SID) isoleucine (Ile), valine(Val), and leucine (Leu). Three 2‐week experiments were carried out with piglets, initially weighing 7 kg and which were pennedindividually. One week after weaning, piglets (16 per treatment) were offered ad libi...
Article
Research on AA requirements and their profile is still running and the recommendations are being updated frequently. The dietary crude protein level could be reduced with no marked detrimental effects on animal performance as far as the supply and the balance of indispensable AA meet the animal requirements. A dose-response experiment was conducted...
Article
For 6 weeks, 256 female finisher pigs (initially 53.9 kg) were fed four dietary treatments of 136, 148, 159 and 168 g crude protein (CP)/kg diet. The latter diet was the 159 g CP/kg diet supplemented with dispensable amino acids, to study the effect of excess CP. Week 4 included use of metabolic cages. Feed intake, gain and feed utilisation were no...
Book
The objective of this study was to determine requirements of standardized ileal digestible (SID) Ile, Val,and Leu relative to Lys that support maximum animal performance. This was studied in 3 dose-responseexperiments with individually penned piglets starting 1 week after weaning. Experimental diets were sublimitingin Lys and included 0.42, 0.46, 0...
Article
Pig diets are supplemented with crystalline amino acids (AA) to balance the AA profile. This is necessary to avoid poor nitrogen (N) utilization, urinary N excretion, and low growth rates. Valine (Val) is one of the branched-chain AA which cannot be synthesized by the animal and therefore is listed as indispensable AA. In European grower diets, Val...
