The Utilization of Fats of Different Melting Points Added to Broiler Feed

Antibiotic Potentiation

“…This agrees with the results of the Cornell group (Renner and Hill, 1958) which found that the saturated fatty acid, stearic, was completely indigestible by the chick. Carver et al (1955) also found that hydrogenated tallow was not efficiently utilized by the chick.…”

Protein and Energy Levels for Turkey Starting Diets

“…White, yellow and brown grease may efficiently be utilized by the chick when fed at the 3% level, whereas a reduction in caloric efficiency has been noted when the same substances were fed at the 6% level (Seidler et al, 1955). Hydrogenated fats or fatty acids, were found not to be absorbed from the intestinal tract and consequently not utilized by the chick (Carver et al, 1955). The addition of 10% tallow to the diet did not increase the growth rate of chicks until the protein level of the diet was increased from 22 to 25%; indicating an increased requirement for protein upon the increase of the caloric content of the diet (Aitken etal., 1954).…”

The Effect of Dietary Energy on the Protein Requirements of Growing Turkeys

“…Sunde (1954b) andCarver~~. (1954) reported that hydrogenated fat and stearic acid would not improve feed utilization.…”
