Book excerpt: In Experiment 3, yearling heifers (n = 407) were synchronized with either the SSC +TAI treatment from Experiment 1 or 7-11 treatment that included melengestrol acetate (MGA; 0.5 mg/head/d) for 7 d with GnRH 4 d after the last day of MGA followed by DPG 7 d later. Estrus was detected and heifers were inseminated similar to Experiment 1. Heifers were distributed to treatment by reproductive tract score (RTS; Scale: 1=immature to 5= estrous cycling) and BCS. The 7-11 heifers had greater (P 0.05) ER (55.2 vs. 41.9%), CR (47.0 vs. 31.3%), and SPR (33.5 vs. 24.8%) compared to SSC+TAI heifers, respectively.

Download or read book Comparison of Different Gonadotropin-releasing Hormone Plus Prostaglandin F[sub-2alpha] Synchronization Protocols in Bos Taurus, Bos Indicus, and Bos Indicus X Bos Taurus Postpartum Cows and Heifers written by Regina D. Esterman and published by . This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Timed-AI pregnancy rates tended (P = 0.06) to be greater, and synchronized pregnancy rates were greater (P 0.05) for cloprostenol sodium (57.2%) compared to dinoprost tromethamine (46.2%). Breed had no effect on synchronized pregnancy rates but as days from calving increased, response to treatment increased. In heifers, estrous response, conception, and synchronized pregnancy rates were similar (P 0.05) across treatments and breeds. In Exp. 4, postpartum Angus (Bos taurus; n = 31) and Brangus (Bos indicus x Bos taurus; n = 22) cows were synchronized with Select Synch plus a new CIDR. Ovarian follicle response to GnRH was monitored using ultrasonography. Breed did not influence ovulation rate to GnRH. Cows which ovulated to GnRH had greater (P
Book Synopsis Strategies for Enhanced Growth and Reproductive Performance of Yearling Bos Taurus and Bos Indicus X Bos Taurus Beef Heifers by : Bradley Ryan Austin
Download or read book Strategies for Enhanced Growth and Reproductive Performance of Yearling Bos Taurus and Bos Indicus X Bos Taurus Beef Heifers written by Bradley Ryan Austin and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultrasound measurements of rump fat, fat over the 13th rib, and longismus dorsi area were decreased for L-H heifers during the first 89 d, but similar by d 174. Blood PUN and NEFA concentrations fluctuated greatly during the trial for both treatments, but plasma glucose concentrations were not affected by treatment. Heifers in the L-H treatment had significantly reduced puberty and pregnancy rates compared to CON heifers. The use of DDG is a viable supplement to developing Angus and Brangus heifers consuming round bale silage. Supplementation of heifers three times a week as opposed to daily is a viable alternative to decrease costs in a heifer development program. Delaying supplementation of heifers to decrease costs is not a viable management decision if forage is not of a high quality.

Download or read book Goat Science written by Sándor Kukovics and published by BoD – Books on Demand. This book was released on 2018-06-20 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: Goat science covers quite a wide range and varieties of topics, from genetics and breeding, via nutrition, production systems, reproduction, milk and meat production, animal health and parasitism, etc., up to the effects of goat products on human health. In this book, several parts of them are presented within 18 different chapters. Molecular genetics and genetic improvement of goats are the new approaches of goat development. Several factors affect the passage rate of digesta in goats, but for diet properties, goats are similar to other ruminants. Iodine deficiency in goats could be dangerous. Assisted reproduction techniques have similar importance in goats like in other ruminants. Milk and meat production traits of goats are almost equally important and have significant positive impacts on human health. Many factors affect the health of goats, heat stress being of increasing importance. Production systems could modify all of the abovementioned characteristics of goats.

Available in PDF, EPUB and Kindle. Book excerpt: This is a book concerned with a strategic area of science. All topics on animal production and comparative physiology are very important to aid in the better understanding of areas related to pet companionship, health sciences and food production. Nowadays, humanity is facing breakthroughs in new technologies, genetics and environmental challenges. This book is an attempt at fulfilling the need for information about the scientific and, most importantly, applied aspects of animal reproduction. Considering the importance of many species that need assisted reproductive technologies, the authors covered the most studied models, including cattle, horses, sheep and others. The authors also exposed the main biotechnologies used in animal assisted reproduction, discussing their indications according to each species to which they are applicable. This book covers topics such as the reproductive physiology of males and females; production of embryo (in vivo and in vitro); cryopreservation of embryos; artificial insemination; control of estrous cycle; hormonal treatments; semen analysis; reproductive ultrasonography; in vitro culture of ovarian follicles; animal cloning; advances on biotechnology of small ruminants; epigenetics in animal reproduction; equine reproduction and ovum pick-up. Over twenty leading scientists from several universities and countries have contributed research to create the first single-source reference on reproductive techniques. It is hoped that this book will be convenient to all categories of people dedicated to animal reproduction, whether they are undergraduate and graduate students, teachers, scientists or practitioners.
