Pantothenic acid studies with turkey poults
1989
Ruiz, N. | Harms, R.H.
Three 21-day battery studies were conducted to determine whether a corn-soybean meal diet without pantothenic acid supplementation was adequate for growth and feed efficiency. In Experiments 1 and 2, a total of 288 day-old Nicholas Large White turkey poults were assigned to four dietary treatments, 0, .8, 1.6, and 3.8 mg of supplemental pantothenic acid per kg of basal diet. In Experiment 3, 240 birds were assigned to the same dietary treatments as in the first two experiments plus an additional treatment of .4 mg of supplemental pantothenic acid per kg. Eight poults (four female and four male birds) were used per pen. The crude protein content of the basal diet was 28.5% in Experiments 1 and 2, and 25% in Experiment 3. The calculated pantothenic acid content was 9.8 mcg per kg in Experiments 1 and 2, and 8.6 mcg per kg in Experiment 3 of the basal diet. Turkey poults grew normally to 21 days of age without any apparent pantothenic acid deficiency sign. However, some improvement in feed conversion was observed in two experiments when pantothenic acid was supplemented to a corn-soybean meal diet.
