Background The effect of amylases combined with exogenous carbohydrase and protease in a newly harvested corn diet on starch digestibility, intestine health and cecal microbiota was investigated in broiler chickens. Methods Two hunderd and eighty-eight 5-day-old female chickens were randomly divided into six treatments: a newly harvested corn-soybean meal diet (control); control supplemented ...

The purpose of this experiment was to determine and compare the digestibility of crude protein (CP) and amino acids (AA) in full-oil (no oil extracted) and de-oiled (oil extracted) corn distillers dried grains with solubles (DDGS) with different condensed distillers solubles (CDS) ratios. Six barrows (29.6±2.3 kg) fitted with ileal T-cannula were allotted into a 6×6 Latin square design. Each pe...

Abstract Dietary zinc (Zn) and copper (Cu) supplementation can affect the digestion absorption of nutrients in pigs, especially minerals. This study aimed to evaluate effect dietary levels Zn Cu on their ileal (AID) total tract (ATTD) digestibility that manganese (Mn), calcium (Ca), phosphorus (P). Six crossbred pigs were surgically equipped with a single-T cannula distal ileum. In cross over d...

Two experiments were conducted to examine the influence of addition of microbial phytase to diets differing in native phytase content, on the performance of sows and digestibility of nutrients. Barley and wheat grains relatively poor in native phytase used in Experiment 1 mixtures were replaced by triticale and rye (rich in this enzyme) in Experiment 2 diets. There were 3 groups in each experim...

To investigate apparent ileal and faecal digestibility of protein and amino acids in some tropical feedstuffs, six barrows, average initial body weight (BW) 25 kg, were fitted with a simple T-cannula at the distal ileum and fed six diets according to a 6 × 6 Latin square design. Three monodiets which three types of cereal, broken rice, rice bran and corn, as the protein source and three cornsta...

In 2 experiments, dose response efficacy of a xylanase and β-glucanase blend (XB) on growth performance and ileal nutrient digestibility was investigated in nursery pigs fed pelleted wheat (Triticum aestivum)- and barley (Hordeum vulgare)-based diets. A basal diet (meeting NRC [1998] specifications for 6 to 30 kg BW, except for 5% lower DE) was supplemented with XB to give 4 diets (0, 50, 100, ...

Two experiments were conducted to evaluate the nutritional value of three cultivars (Promore, Kiev mutant and Ultra) of white lupins (Lupinus albus L.) for broilers. In experiment 1, the apparent metabolisable energy (AME) and ileal amino acid digestibility coefficients of the three cultivars were determined. The cultivar effects were significant (P < 0.05) for AME, but the ileal amino acid dig...

Two experiments were designed to determine the N and AA digestibility of various protein sources (potato protein concentrate, soy protein concentrate, soy protein isolate, linseed meal, sunflower meal, cottonseed meal, canola meal, and camelina meal) fed to growing pigs. In each experiment, barrows were surgically fitted with a simple T-cannula at the distal ileum and fed 4 experimental diets a...

The effects of phytase supplementation on the apparent ileal digestibility (AID) of amino acids (AA) have been inconsistent. Two experiments evaluated the effect of providing a mixture of pancreatic enzymes (Pancreatin(®) ) to growing pigs fed sorghum-soybean meal diets supplemented with phytase on the AID of AA, energy, and phosphorus (P), as well as the ileal digestibility (ID) of phytate; th...

Most pulse (nonoilseed legume) seed flours can be fractionated rapidly and economically by air classification into protein and starch concentrates. The nutritional value of air-classified field pea and faba bean concentrates requires characterization to assess the feeding opportunity for pigs. Thus, the objectives were to characterize the apparent total tract digestibility (ATTD) of DM, OM, ene...
