I. Six 45 kg pigs with re-entrant ileal cannulas were used in two 3 x 3 Latin-square design experiments to study the site of absorption of protein and amino acids. Semi-purified diets containing soya-bean meal (SBM), rapeseed meal (RSM) or no protein source (protein-free) were offered at the rate of I kg dry matter/d. 2. Flow-rates of ileal contents for 24 h collection periods, corrected for re...

Using ileal digestible amino acids in feed optimising will intensify feed protein utilizing and decrease nitrogen excretion to the environment. The study determined the apparent ileal digestibility (AID) coefficients of amino acids in barley, wheat, oats, triticale, maize, and dehulled oats in the diets of 180 Ross broiler chickens (aged 24–35 days). The birds were fed semi-purified diets that ...

Two experiments were conducted to evaluate the effects of diet complexity and fermented soy protein on growth performance and amino acid digestibility. In Exp. 1, a total of 120 crossbred weanling pigs (5.68±0.80 kg BW) were randomly allocated into 4 treatments. Each treatment had 6 replicate pens comprising 5 pigs in each replicate. Experimental diets consisted of simple (soybean meal as prote...

Background: Previous research indicates that young children in low-income countries (LICs) generally consume greater amounts of protein than published estimates of protein requirements, but this research did not account for protein quality based on the mix of amino acids and the digestibility of ingested protein.Objective: Our objective was to estimate the prevalence of inadequate protein and a...

The high consumer demand in Indonesia encourages catfish farmers to conduct an intensive culture. A low feed efficiency mainly occurs cultivating Sangkuriang resulting poor growth. This condition might be caused by lysine content, as is essential amino acid that the fish cannot synthesize. present study aimed investigate effect of supplementation on protein digestibility, efficiency, and growth...

A lamb digestion trial was conducted to compare the ability of internal markers to predict digestibility of alfalfa. Lambs were fed alfalfa hay grown with varying amounts of water stress where water per harvest ranged from 10 to 20 cm/ha and yield ranged 1400 to 4200 kg/ha. In vivo dry matter digestibility was most highly correlated with digestibility determined using acid detergent fiber insol...

An experiment was conducted to determine whether the effects of phytase on amino acid (AA) and energy digestibility in pigs is influenced by the concentration of dietary P. Fourteen barrows (initial BW: 37.8 ± 4.7 kg) were surgically fitted with a T-cannula in the distal ileum and randomly allotted to a replicated 7 × 7 Latin square design with 7 diets and 7 periods. Six diets were formulated t...

Soybeans is an important crop in the United States and are primarily used for animal feed, human food, and production of biofuels. Soybean meal (SBM) and other soy products contribute high-quality protein to diets fed to pigs because soy protein is rich in the limiting amino acids lysine, threonine, and tryptophan that are present in relatively low concentrations in the most commonly fed cereal...

This study aimed to in vitro evaluate the impact of common gastrointestinal (GI) alterations appearing with aging on protein digestibility, and functional related properties, four different meats (chicken, turkey, pork beef). Thus, three elderly digestion models were stated as long altered GI conditions affected at oral (E1), gastric (E2) oral, intestinal stages (E3). Healthy adult also mimicke...
