examine the effects of ovulatory follicle size and periovulatory peripheral concentrations of E2 and IGF-1 on embryo survival
establish the relationships between ovulatory follicle size and subsequent corpus luteum size and peripheral concentrations of P4 and their effect on embryo survival
The relationship between periovulatory endocrine and follicular activity on corpus luteum size, function, andsubsequent embryo survival
examine the relationships between the intervals from the onset of heat to AI and from AI to ovulation and embryo survival.
heifers were kept on slatted floor pens and had ad libitum access to grass silage
After this, animals were turned out to pasture and remained at pasture until final pregnancy diagnosis at 100 d after AI.
