Dietary vitamin K1 requirement and comparison of biopotency of different vitamin K sources for young turkeys.
In a preliminary experiment, the inclusion of vitamin K1 (K1) at a dietary level of 0.1 mg/kg was as effective as 1 or 2 mg/kg in reducing plasma prothrombin time (PT). To obtain an estimate of the dietary K1 requirement and to compare the biopotency of different vitamin K sources for poults, three additional experiments were conducted. In Experiment 1, an incomplete factorial arrangement of tr...
متن کاملDigestible lysine requirement of female turkeys during the starter period.
Three experiments were conducted to determine the digestible lysine requirement of female turkey poults during the starter period. Birds were fed a standard corn-soybean meal diet until the onset of each trial and were then randomly assigned to treatments that were fed for 2 wk. Dietary treatments included titrated levels of digestible lysine (1.18 to 1.72%) added to a basal corn-soybean meal d...

متن کاملCholine requirement of young swine.
Three experiments were conducted to study the dietary choline requirement of young swine. Ninety pigs (three replicates), in the first experiment, and 120 pigs (four replicates), in the second experiment, were allotted to the five choline treatments (0, 330, 660, 990 or 1320 mg choline/kg of diet), fed in a 23% crude protein, semi-purified diet (.31% methionine, .33% cystine). The combined resu...
متن کاملEfficacy of Phytase Preparations to Improve P Availability in Young Turkeys
Phytate phosphorus of plant ingredients is not substantially available to poultry because of the lack of endogenous phytase enzymes in their gastrointestinal tract. There are substantial differences among broilers, turkeys, and ducks in terms of plant P utilization. We studied whether the availability of P is different for two Phytase enzymes in turkeys. Finase and a New Phytase product develop...
