A 42-d trial was conducted to study the influence of 2 plant extracts on performance, digestibility, and digestive organ weights in broilers. The feeding program consisted of a starter diet until 21 d and a finisher diet until 42 d. There were 4 treatment groups: control; 10 ppm avilamycin (AB); 200 ppm essential oil extract (EOE) from oregano, cinnamon, and pepper; and 5,000 ppm Labiatae extra...

The techniques of post-valve ‘‘T’’ caecal cannulation (PVTC) and ileo-rectal anastomosis (IRA) and the indigestible markers Cr O and TiO for determination of ileal digestibility of nutrients were studied in this experiment. The results 2 3 2 showed that the marker Cr O gave consistently lower ileal recovery and ileal apparent digestibility of nutrients. The 2 3 average value of ileal recovery o...

Two experiments were conducted to evaluate effects of coated compound proteases (CC protease) on apparent total tract digestibility (ATTD) of nitrogen (N) and energy, and apparent ileal digestibility (AID) of amino acids (AA) and nutrients in diets for pigs. In Exp. 1, 12 crossbred barrows (initial body weight: 20.14±1.71 kg) were housed in individual metabolism crates and allotted into 2 treat...

1. Four human subjects on strictly controlled diets were given a fibre supplement, 25 g Ispaghula husk (Isogel)/d, for 3 weeks. 2. Replicate diets and faeces were collected during two 5 d balance periods. The first period served as control for the second which occurred after the supplement had been fed for 2 weeks. 3. Diets and faeces were analysed for total solids, gross energy, total nitrogen...

OBJECTIVE This study investigated the effect of microbial phytase supplementation on growth performance, tibia ash, plasma parameters, apparent ileal digestibility (AID) of amino acid (AA) and apparent digestibility of nutrients in Youxian Sheldrakes fed with low-phosphorus (P) corn-soybean diets. METHODS A total of 350 Youxian Sheldrakes (7d old) were randomly divided into 5 treatment groups...

Most of amino acid (AA) digestibility values for feed ingredients are obtained using pigs cannulated in the distal ileum. The ileal-cannulated pig model uses pigs older than six weeks due to difficulties related to implanting the T-cannula in distal ileum of younger pigs and complications during the post-surgical recovery. However, to properly formulate the diet of weaned pigs, the nutritive va...

ABSTRACT- This study was designed to investigate the effects of adding different levels of date presscakes (DP), with and without enzyme supplementation (ES), on the ileal digestibility and growth performance of broiler. A completely randomized design containing 2 × 5 factorial arrangement of treatments (with and without enzyme supplementation and 5 levels of DP) was used. The enzyme complex co...

Two trials were conducted to evaluate the effects of dietary NPN levels on animal performance, diet digestibility, ruminal characteristics, and microbial efficiency. Experiment 1 was conducted with 24 Holstein x Nellore crossbred steers (350 +/- 20 kg of BW) distributed in 6 blocks to evaluate intake and digestibility of nutrients and performance. The diets consisted of 70% corn silage and 30% ...
