One-hundred-twenty Babcock B-300 ehns, 17 months of age, were placed one bird per cage with six replicates of five birds each per treatment. Four levels (0, 1, 2, and 4%) of technical grade tannic acid were added to a standard corn-soy layer diet. With the exception of feed comsumption during the second and third week, there were no significant differences for feed consumption, egg production, feed efficiency, fertility, or hatchability amond the control birds and those receiving tannic acid at the 1% level. The addition of tannic acid at levels of 2 and 4% resulted in significantly decreased feed consumption and egg production during the six-week experimental period. Fertility and hatchability were not significantly affected by dietary tannic acid.
Two experiments were conducted to evaluate the relative efficiency of methionine and methionine hydroxy analogue-calcium (MHAC) in the diet of turkey poults. A corn-soybean diet containing 25% protein and 2583 kilocalories of metabolizable energy per kilogram was utilized. Five experimental diets were fed: basal, 0.04 and 0.08% supplemental DL-methionine and 0.04 and 0.08% supplemental MHAC. In both experiments eight pens of seven poults were fed each experimental diet. This resulted in a total of 16 replicate pens receiving each diet. Body weight and feed efficiency were measured at four weeks of age. The MHAC, on a weight basis, was found to have 82.4 and 82.8% activity of DL-methionine based on body weight and feed efficiency, respectively.
