Abstract
The pituitary hormonal content in seven heifers treated with 1120 mg. of progesterone 6 days before slaughter was compared to that of seven control heifers. Exogenous progesterone in amounts capable of inhibiting estrus and ovulation had no detectable effect on the hormonal content of the anterior pituitary of beef heifers regarding FSH, ICSH, TSH and GH stimulating activity. The ratio of ICSH:FSH activity of beef heifer anterior pituitary is 6:1. Copyright © . .This publication has 5 references indexed in Scilit:
