Available in PDF, EPUB and Kindle. Book excerpt: Abstract: To increase the adoption of artificial insemination (AI) in cattle, timed-AI (TAI) programs in which AI is performed without the necessity of estrous detection, were developed. With the ability to manipulate the estrous cycle and follicular development concurrent with the enhancement of these approaches, much has been learned about the factors during follicular development that affect fertility. In some approaches, it has been clearly demonstrated that the diameter of the ovulatory follicle has a major effect on fertility. Others have shown that fertility is influenced by the length of proestrus. More recent data suggests that age of the ovulatory follicle may also impact fertility; however this has not been investigated in beef cattle. In the first experiment, age of ovulatory follicle and its effect on conception rate were investigated in beef heifers in Montana (MT) and Ohio (OH). The animal model used created a difference in follicle age of approximately 3 d between treatments ("young" follicle, YF; and "mature" follicle, MF). Ultrasonography was performed to assess follicular characteristics and development, and for pregnancy status. AI was performed approximately 12 h after onset of estrus. Interval to estrus was greater and follicle diameter at AI was smaller in the YF than in the MF treatment, however no difference was detected in conception rates. In the second experiment, the effect of ovulatory follicle age on pregnancy rate was investigated in beef cows in MT. Follicle age differed by approximately 3 d at the time of AI between treatments (YF and MF). Ultrasonography was performed throughout the experiment for follicular characteristics and pregnancy diagnosis. Estrous detection was performed for 3 d and 4 d in the MF and YF, respectively, followed by AI approximately 12 h later. Cows not detected in estrus during this period, received an injection of GnRH and TAI either at 72 h (MF) or 96 h (YF) after prostaglandin (PGF) administration. Follicle diameter at AI did not differ between treatments; however interval to estrus was greater in the YF than in the MF. Pregnancy rates were similar between treatments. Across treatments, pregnancy rate was greater in cows that were AI after estrus, than cows that received TAI. In conclusion, manipulation of ovulatory follicle age in beef cattle resulted in a longer interval to estrus (heifers and cows), and smaller follicle diameter at AI (heifers) in animals treated in a manner to result in ovulation of younger follicles, but age of the follicle at AI did not influence pregnancy rate. This data suggest that age of the ovulatory follicle is not a major contributor to variation in fertility in beef cattle.

Book Synopsis Improving Beef Cattle Reproductive Efficiency by : McKenzie R. Corpron
Download or read book Improving Beef Cattle Reproductive Efficiency written by McKenzie R. Corpron and published by . This book was released on 2020 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Less than 10% of beef cow-calf producers in the United States currently implement reproductive technologies such as estrous synchronization and artificial insemination (AI) as a component of their breeding management program. Synchronization protocols aid in the synchrony of estrus and ovulation to improve cattle fertility, however, many protocols often require multiple hormone injections and animal handlings. Development of estrous synchronization protocols that limit number of injections, cost, and labor inputs, without compromising fertility, may improve the adoption of fixed-time artificial insemination (FTAI) within the beef industry. The main objective of the first study was to compare the effect of a single injection of high-concentration (HICON) prostaglandin F2[alpha] (PGF) or two conventional PGF injections (2PGF) administered 8 h apart at controlled internal drug release insert (CIDR) removal, on reducing serum progesterone (P4) before FTAI and on subsequent pregnancy per artificial insemination (P/AI) in postpartum beef cows (n=404) synchronized with a 5-d CO-Synch + CIDR breeding program. Serum P4 concentration at the time of insemination is a determining factor of cattle fertility in FTAI protocols, as lower concentrations have been associated with increased P/AI. A secondary objective of the first study was to assess the relationship between P4 concentration at the time of insemination and probability of pregnancy to AI. Progesterone concentrations at AI were lesser in 2PGF than HICON, however, P/AI was not different between treatments. Probability of pregnancy decreased as P4 concentration at AI increased and the optimal P4 cutoff concentration to optimize fertility was determined at 0.43 ng/mL. Intramuscular (i.m.) route of injection is commonly used to administer products used in estrous synchronization in beef cattle; however, this route causes greater incidence of injection-site lesions and tissue damage associated with reduced beef carcass quality and tenderness than subcutaneous (s.c.) routes. Therefore, use of s.c. administration is favorable to reduce carcass damage. The objective of the second study was to compare the ability of a single s.c. injection of high-concentration PGF (HICON-SC) with two i.m. injections of conventional PGF 6 h apart (2PGF-IM) to reduce P4 concentration and induce luteolysis by the time of AI in a 5-d CO-Synch + CIDR synchronization program in postpartum beef cows. A similar decline in P4 concentration occurred in both treatments following PGF, indicating s.c. administration of HICON could be an effective alternative to i.m. administration of the conventional double PGF dose to induce luteolysis before AI in the 5-d CO-Synch + CIDR protocol.
