This book was released on 2006 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Single and multiparous registered Angus cows and heifers were synchronized and artificially inseminated at a set time (Timed Artificial Insemination, TAI) to determine the effects of TAI and estrus synchronization protocols on actual estrus and to determine the effect of insemination time on conception following TAI. Trial 1 was a project to adjust times in Trial 2 using crossbred multiparous cows. Trial 2 consisted of Angus heifers (n=19) and Angus cows (n=54). Treatments were a synchronization protocol in addition to adjusted insemination times by several hours between treatments. Results of the heifers and cows were similar. Heifers and cows data showed differences in conception on first TAI (P

Book excerpt: Efficiency of reproduction is crucial for successful cow-calf operations. Cows naturally have varying timing of estrous cycles between cohorts and manipulation of current estrus synchronization and artificial insemination (AI) techniques may prove pivotal in increasing conception rates. The objective of these experiments was to determine if alternative methods of estrus synchronization or AI may increase incidence of successful fertilization and pregnancy, either by bull or AI. In Exp. 1, 168 (n = 84 each year) crossbred and purebred Angus two and three year old beef cows were randomly assigned to one of two estrus synchronization treatment groups: 1) a Controlled internal drug release (CIDR) and GnRH administration d-7, removal of CIDR and PG administration d 0, or 2) PG administration on d 5. Bulls were turned out d 0 at a bull to cow ratio of 1:17 for 90 d. Blood samples were taken approximately 30 d after bull turn out and 45 d after bull removal to determine pregnancy. Estrus detection patches were used to determine estrus. Although estrus response was greater in CIDR than PG (P = 0.02), early pregnancy (P = 0.92) and final pregnancy rates (P = 0.89) were not different. However, estrus response in the first 5 d was greater (P

This book was released on 2015-08-25 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the result of academic work experience of estrous synchronization operations under project conducted by ILRI. It sets out to fill a gap in the literature available on the reproduction of dairy cattle and genetic improvement of the Africa. It is important to know how to use different hormones and in different seasons of dairy cattle. As estrous synchronization is an integral part of reproductive biotechnology and has many functions and uses the determination of reproduction and genetic improvement tools are accessible to non specialists in reproductive biotechnology, be they technicians working in AI, animal genetics and breeding, animal production, teachers or students. This book is a reference for any one in a need of information on the estrous synchronization of dairy cattle of the region.

Download or read book Artificial Insemination in Farm Animals written by Milad Manafi and published by . This book was released on 2011 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Artificial insemination is used instead of natural mating for reproduction purposes and its chief priority is that the desirable characteristics of a bull or other male livestock animal can be passed on more quickly and to more progeny than if that animal is mated with females in a natural fashion. This book contains under one cover 16 chapters of concise, up-to-date information on artificial insemination in buffalos, ewes, pigs, swine, sheep, goats, pigs and dogs. Cryopreservation effect on sperm quality and fertility, new method and diagnostic test in semen analysis, management factors affecting fertility after cervical insemination, factors of non-infectious nature affecting the fertility, fatty acids effects on reproductive performance of ruminants, particularities of bovine artificial insemination, sperm preparation techniques and reproductive endocrinology diseases are described. This book will explain the advantages and disadvantages of using AI, the various methodologies used in different species, and how AI can be used to improve reproductive efficiency in farm animals.

Download or read book Comparison of Long term CIDR based Protocols to Synchronize Estrus in Postpartum Beef Cows written by Justin Michael Nash and published by . This book was released on 2011 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Estrus synchronization and artificial insemination are two of the most important management practices available to producers to increase reproductive performance in a beef cow-calf operation. Unfortunately, a small number of producers utilize these practices due to increased labor requirements. The use of fixed-time artificial insemination (FTAI) reduces the amount of time and labor required to detect estrus, leading to decreased input requirements. The following experiments were performed in order to compare the use of long-term controlled internal drug release (CIDR) insert-based estrus synchronization protocols prior to FTAI in estrous-cycling and anestrous postpartum beef cows. In experiments 1 and 2, two long-term CIDR-based estrus synchronization protocols were compared on the basis of physiological characteristics, including serum steroid hormone concentrations, estrous response, and follicular dynamics, as well as pregnancy rates resulting from FTAI. From these intensive trials, it was determined that both protocols yielded comparable pregnancy rates and similar physiological responses when used in postpartum beef cows. In experiment 3, the use of either a long- or short-term CIDR-based estrus synchronization protocol was compared prior to FTAI in a large-scale field trial. Results indicated that pregnancy rate resulting from FTAI was similar for both protocols. These data provide preliminary support for the use of long-term CIDR-based estrus synchronization protocols prior to FTAI in postpartum beef cows.
