The processes of natural selection shape the efficiency of nutrient use by animals, with some being especially thrifty while others are wasteful. An examination of the widely divergent amino acid economies of different species vividly illustrates this basic nutritional principle. The domestic cat evolved as a carnivore and has a very high maintenance requirement for dietary amino acids. The cat’s very high basal rate of amino acid catabolism, also referred to as minimal, obligatory, or… Expand
Biomarkers for optimal requirements of amino acids by animals and humans.
TLDR
This review summarizes the current approaches to assess amino acid requirements of animals and humans, as well as the recent development of biomarkers as potentially functional parameters for recommending requirements of individual amino acids in health and disease. Expand
Dietary L-Homoserine Spares Threonine in Chicks 1 , 2
Four chick bioassays were conducted to evaluate the threonine (Thr) replacement value of L-homoserine (HS). Growth rate was increased (P , 0.05) by dietary addition of 800 mg L-HS/kg diet to aExpand
Dietary L-homoserine spares threonine in chicks.
TLDR
The results indicate that low levels of HS elicit a growth response in young chicks fed Thr-deficient diets, and threonine (Thr) replacement value of l-homoserine (HS) is predicted to be 38 +/- 9% for HS. Expand

Dietary lysine requirement for 7–16 kg pigs fed wheat–corn–soybean meal‐based diets
TLDR
On average, optimal dietary SID lysine content for optimal growth of 7-16 kg weaned piglets fed wheat-corn-SBM-based diets was estimated to be 1.32%; at this level, the ADG and ADFI were 444 and 560 g, respectively, thus representing an SIDLysine requirement. Expand
Using Nutritional Strategies to Shape the Gastro-Intestinal Tracts of Suckling and Weaned Piglets
TLDR
This review summarises a large body of literature on nutritional strategies aimed at supporting gut health in piglets, combining individual strategies into a structured nutritional approach over time, starting from a few days after birth to 5–6 weeks post-weaning. Expand
A diet rich in dietary fiber from cocoa improves lipid profile and reduces malondialdehyde in hypercholesterolemic rats.
TLDR
The consumption of CF with a hypercholesterolemic diet improved the lipidemic profile and reduced lipid peroxidation, suggesting that CF might contribute to a reduction of cardiovascular risk. Expand
Histological parameters to evaluate intestinal health on broilers challenged with Eimeria and Clostridium perfringens with or without enramycin as growth promoter
TLDR
Histological parameters that explain the effect of enramycin as growth promoter on intestinal health in broilers challenged with Eimeria and Clostridium perfringens are established and suggest these 2 histological parameters as a standard to compare products for gut health. Expand
Probiotic as a Novel Treatment Strategy Against Liver Disease
TLDR
Probiotic therapy as a safe, inexpensive and a noninvasive strategy can reduce pathophysiological symptoms and improve different types of liver diseases without side effects. Expand

Protein requirements of rainbow lorikeets, Trichoglossus haematodus
TLDR
The natural diet of rainbow lorikeets is low in protein but in captivity their diets contain relatively high concentrations of protein, indicating an unusually low digestibility for egg white protein. Expand
Maintenance lysine requirement and efficiency of using lysine for accretion of whole-body lysine and protein in young chicks.
TLDR
The data demonstrated that at nitrogen equilibrium, chicks are in negative Lys balance but are in positive balance of glycine and proline. Expand
Estimate of the variability of the lysine requirement of growing pigs using the indicator amino acid oxidation technique.
TLDR
The short (< 3 wk) experimental period allows, for the first time, the estimate of population variability, which provides for more accurate calculation of the effect of altering Lys intake on herd performance and production economics. Expand
Influence of dietary lysine and energy intakes on body protein deposition and lysine utilization in the growing pig.
TLDR
The serial slaughter study and N balances indicated that MEI and IDLys had independent effects on PD and lysine utilization, and Lysine utilization and PD increased with increasing MEI until plateau values were reached. Expand
Response to lysine intake in composition of body weight gain and efficiency of lysine utilization of growing male chickens from two genotypes.
TLDR
It was concluded that the efficiency of amino acid utilization may depend on genotype, perhaps due to differences in the relative proportion of different protein fractions to whole body protein and due to Differences in the ratio of synthesis and degradation of body proteins. Expand
Feeding frequency and type of isotope tracer do not affect direct estimates of lysine oxidation in growing pigs.
TLDR
Isotope tracer studies that cover one or more complete feeding cycles, i.e., feeding-to-feeding periods, can be used to obtain valid daily lysine oxidation values. Expand
Protein Requirements of Costa's Hummingbirds Calypte costae
TLDR
The bodymass data indicated that adult, nonreproducing hummingbirds have a low protein requirement, compared with published time-budget studies of free-living hummingbirds, which have shown that the birds spend most of their feeding time foraging for nectar to meet their high energy needs. Expand
α-Aminoadipate δ-Semialdehyde Synthase mRNA Knockdown Reduces the Lysine Requirement of a Mouse Hepatic Cell Line
TLDR
Results indicate AASS knockdown decreases the lysine requirement of the cell via a reduction of l Lysine catabolism through AASSmRNA knockdown. Expand
Knockdown of porcine endogenous retrovirus (PERV) expression by PERV‐specific shRNA in transgenic pigs
TLDR
RNA interference is a promising option to inhibit PERV transmission and may be associated with the transmission of porcine endogenous retroviruses during xenotransplantation using porcines cells, tissues or organs. Expand
