Effect of microbial phytase on apparent digestibility and retention of phosphorus and nitrogen in growing pigs
Six female pigs of approximately 50 kg BW, fitted with simple T-cannula in the terminal ileum, were used to study the effect of microbial phytase on apparent total tract digestibility and retention of P and N. Three P-adequate diets (digestible P concentration 2.3 g/kg) containing barley (B), soybean meal (S) or their mixture (BS) with or without phytase supplement (1 000 FTU/kg) were fed to pi...
متن کاملDevelopments in Alternative Feedstuffs for Pigs
Feed cost remains the largest portion of the variable costs in swine production. To control feed cost, swine producers or their nutritionist continue to look for alternative feedstuffs. Reasons to include alternative feedstuffs in swine diets might be a desire to improve pork quality, nutrient management, animal health, or animal welfare. The main criterion for successful incorporation of alter...
متن کاملIleal and Faecal Amino Acids Digestibility of Some Tropical Feedstuffs in Growing Pigs
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...
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...
