Download or read book Factors Affecting Calf Crop written by Michael J. Fields and published by CRC Press. This book was released on 2021-11-18 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: Factors Affecting Calf Crop summarizes the latest information available from leading cattle physiologists and geneticists regarding factors known to influence the production of live calves at weaning. You get practical information on management techniques for improving reproduction efficiency in the herd. You'll also learn about the functioning of the reproductive system and how this may affect reproductive processes in the cow herd. Managers will benefit from a clearer understanding of the factors known to limit efficient reproduction, while veterinarians and other professionals who advise cattlemen will appreciate the substantial reference material and color photographs for defining cow condition scores. Color photographs are also used to illustrate the discussions of testicular thermographies and their applications. Other chapters in the book cover developments in improving reproductive performance of the replacement heifer, the brood cow, and the bull. Topics on reproduction include physiology/endocrinology, the use of growth promotants, genetics and physiological and economic considerations in selecting the age to breed heifers, heritability of fertility, length of the breeding season, prepartum and postpartum nutrition, nursing by the calf, cloning of embryos, and much more.

This book was released on 2013 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fall calving cows were used to determine the effects of protein supplementation on reproduction, and growth and carcass characteristics of calves. Cows were individually supplemented from mid-November to mid-March for four years with either a control diet (Con; 1.82 kg/d of 38 % CP) or low diet (L; 0.2 kg/d of 8% CP). During each year, cows were reassigned dietary treatments according to calving date and BCS, with half of Con and L cows remaining on the same diets as the previous year and the other half assigned to the other diet. Cows were exposed to bulls for 60 d beginning December 1. Statistical analyses were performed with a 2 x 2 factorial design with PROC GLM and PROC FREQ. Cows on Con diets lost less BW from November to January compared with L cows (-29.8 ± 2.8 and -49.7 ± 2.8 kg, P

Download or read book Nutrient Requirements of Beef Cattle written by Subcommittee on Beef Cattle Nutrition and published by National Academies Press. This book was released on 2000-05-16 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: As members of the public becomes more concious of the food they consume and its content, higher standards are expected in the preparation of such food. The updated seventh edition of Nutrient Requirements of Beef Cattle explores the impact of cattle's biological, production, and environmental diversities, as well as variations on nutrient utilization and requirements. More enhanced than previous editions, this edition expands on the descriptions of cattle and their nutritional requirements taking management and environmental conditions into consideration. The book clearly communicates the current state of beef cattle nutrient requirements and animal variation by visually presenting related data via computer-generated models. Nutrient Requirements of Beef Cattle expounds on the effects of beef cattle body condition on the state of compensatory growth, takes an in-depth look at the variations in cattle type, and documents the important effects of the environment and stress on food intake. This volume also uses new data on the development of a fetus during pregnancy to prescribe nutrient requirements of gestating cattle more precisely. By focusing on factors such as product quality and environmental awareness, Nutrient Requirements of Beef Cattle presents standards and advisements for acceptable nutrients in a complete and conventional manner that promotes a more practical understanding and application.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Our objective was to evaluate the effects of pre- and post-partum bolus injections of a trace mineral solution on beef cow reproductive performance, body weight (BW) change, and body condition score (BCS) change and on performance of suckling calves. Mature beef cows (n = 460; initial BW = 497± 89 kg, initial BCS = 5.4± 0.74) were stratified by BCS, parity, and predicted calving date and assigned randomly to 1 of 2 treatments: 1) subcutaneous trace mineral (TM) injection containing 15 mg/mL Cu, 5 mg/mL Se, 10 mg/mL Mn, and 60 mg/mL Zn or 2) subcutaneous injection of physiological saline (SA). Injections were administered to cows (1 mL / 90 kg BW) 105 days before the first projected calving date and again 30 days before fixed-time AI. Calves received the same treatment as their dams and were injected (1 mL / 45 kg BW) at birth and again at 71± 21 days of age. Cows grazed native pastures for the duration of the study; trace mineral supplements and white salt were available to all cattle ad libitum before and during the study. Ovulation was synchronized using a 5-d CO-Synch + CIDR protocol and cows were inseminated 60 to 64 hours after CIDR removal. Cows were exposed to fertile bulls for natural-service breeding 10 days after AI for 35 to 50 days. Conception to AI and final pregnancy rate were assessed 36 days after AI with ultrasound and 120 days after AI via rectal palpation. Change in BW and BCS from initiation of the study to calving and from AI to weaning did not differ (P [equal to or greater than] 0.15) between TM and SA cows. Conversely, TM cows had greater (P = 0.04) BCS increase than SA cows between calving and AI. Calf BW at birth, ADG, and age-adjusted weaning BW did not differ (P [equal to or greater than] 0.36) between treatments. Proportion of cows with estrus cycles 17 and 8 days before ovulation synchronization was similar (P [equal to or greater than] 0.51) between treatments. Conception to AI was greater (P = 0.05) for cows receiving TM (60.2%) than for cows receiving SA (51.2%); however, overall pregnancy did not differ (P = 0.24) between treatments and averaged 92%. Under the conditions of our study, pre- and post-partum TM injections improved conception to fixed-time AI by beef cows.
Download or read book Winter Supplementation and Delayed Weaning of an Autumn Calving Beef Herd Under Western Oregon Conditions written by Heidi Renata Buehner and published by . This book was released on 1986 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two management systems were evaluated in terms of the effects on cow condition score and body weight changes and calf growth rates. The management systems evaluated were winter supplementation of energy, winter creep feeding and delayed weaning. The calves used in this study were born in September and October of 1981. The 48 cows and their calves were brought to a feedlot situation in December and allotted to four groups to allow controlled feeding of an energy or a non-energy supplement to the cows and a creep feed to the allotted calves. The cows receiving 3.64 kg rolled barley/head/day were not different in either body weight or condition score (1 to 5 condition score scale) from the cows fed a protein (non-energy) supplement which was fed at a level to provide the equivalent protein intake for all the cows. That is, there was no effect of the additional energy present in the rolled barley on the performance of the cows or their nursing calves. Creep feeding had a significant effect on calf end weight (P=.001) and calf rate of gain (P=.001). The creep fed calves were on the average 12.95 kg heavier at the end of the trial and gained an average of 9.34 kg more than the calves not creep fed. Creep feeding, though, in today's marketplace may not be a cost effective alternative for the commercial beef producer. Delayed weaning (DW) significantly increased the ADG of calves between the ages of 196 to 266 days of age (P=.001). Steers gained significantly faster than the heifers during this period (P=.001). DW calves did not have a significantly higher ADG than the control (C) calves during the postweaning period (to yearling age), but the DW ADG from 196 days of age to yearling age was still significantly greater than the C calves (P=.001). Postruminal digestion of milk during the experimental period may be the reason for the additional gains by the DW calves. Delayed weaning of fall born calves appears to be a sound management alternative under western Oregon conditions. Winter supplementation of cows and/or calves during the winter months did not realize significant changes in body weight and condition or the profitability of the sale of beef calves.
