Effect of common antinutritive factors and fibrous feedstuffs in pig diets on amino acid digestibilities with special emphasis on threonine.
Most feedstuffs contain antinutritive factors (ANF) such as insoluble fibers, lignins, tannins, and lectins. Intake of these ANF has the ability to reduce nutrient digestibility and to increase endogenous protein losses, such as through increased intestinal mucus secretion. The objective of this experiment was to determine the apparent ileal digestibilities (AID) of AA of 6 ANF-enriched diets t...
متن کاملEstimating endogenous amino acid flows at the terminal ileum and true ileal amino acid digestibilities in feedstuffs for growing pigs using the homoarginine method.
True ileal lysine digestibilities were determined using the homoarginine (HA) method in casein-, barley-, canola meal-, and barley-canola meal-based diets fed to growing pigs. Four Yorkshire barrows (25 to 49 kg BW) equipped with ileal T-cannulas were fed one of the diets according to a 4 x 4 Latin square design. All diets, except for the barley diet, were formulated to be similar in DE:CP rati...
متن کاملThe Determination of Amino Acid Digestibility in Poultry Feedstuffs
Measurements were made on protein sup,plcments in.a basal diet, of dry matter, nitrogen and amino acid digestibilities using mature and' adult cockerels. Birds were killed 5h after receiving their diet in a single feed. Analyses were made on digesta from (i) the ileum, (ii) the terminal ileum, (iii) post caeca, and on excreta. In a second exDeriment -adult cockerels were fitted with a sitiple c...
متن کاملModeling Amino Acid Requirements for Turkeys
Feed costs are the major cost of live turkey production. With recent use of grain and oilseeds for bio-energy production and increased need for feed worldwide, we have seen significant cost increases for feed ingredients and thus to the overall cost of turkey feed. While initially this was thought to be a market swing, it now appears that higher input costs are the norm and thus efforts to redu...
متن کاملAmino Acid Availability in Feedstuffs for the Growing Pig
Assessing amino acid (AA) availability in dietary ingredients is integral to the optimal formulation of diets both in terms of maximising nutrient utilization and profitability. Although the concept that nutrients in feedstuffs are not fully absorbed and metabolized by the animal is now widely accepted, a distinction needs to be made between the concepts of digestibility and availability. Diges...
