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 385 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.

Download or read book Impact of Increasing Level of Milk Production on Cow and Calf Behavior and Performance in the Nebraska Sandhills written by Selby L. Boerman and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Selection for increased milk production across the United States has resulted in variable cow and calf production responses. Better understanding of calf nursing and grazing behaviors may provide opportunities to help estimate how milk and grazed forage intake influence variability in calf performance. In a 2-yr study, cow-calf pairs (n = 65) were equipped with neck collars containing global positioning system (GPS) units to validate the efficacy of high-frequency GPS data to accurately identify calf nursing events and grazing behavior. Data were collected during 3-wk tracking periods during early lactation (calf age 65.4 ± 10.0 d; EARLY) and late lactation (calf age 162 ± 22.3 d; LATE). Calf behavior was visually observed for a total of 350 hrs and was used in a training dataset for a random forest (RF) classification model. Out of bag (OOB) estimates of individual behaviors indicated relatively low misclassification error rates, less than 4%, suggesting that high frequency GPS tracking can be used to effectively classify calf nursing and grazing behaviors. Behavior prediction results in this study match ranges reported in previous literature, supporting the efficacy of this technique to assess behavior in beef calves. In a 2-yr study, crossbred cow-calf pairs (n = 118) from March- and May-calving herds were used to determine the impact of increasing total milk production on cow body weight (BW), body condition score (BCS), reproductive performance, calf BW, and calf average daily gain (ADG). On approximately 30, 60, 90, 120, and 210 d postpartum, individual cow 24-h milk yield was estimated with weigh-suckle-weigh techniques. Milk area under the curve (AUC) values were calculated and data were analyzed using linear regression analysis. Cow BW, BW change, and reproductive performance were not (P > 0.12) associated with milk AUC, except for a tendency (P = 0.09) for lower BW at breeding. At weaning, cow BCS was negatively associated (P = 0.09) with increasing milk AUC but was not associated at any other physiological stage. A significant positive association with calf average daily gain (ADG) was observed from birth to age 120 d and a tendency (P = 0.09) for a positive association was observed from age 120 d to weaning. Steer ADG in the finishing phase was not (P = 0.63) associated with dam milk production. In this environment, increasing milk production had a positive increase in calf growth during the pre-weaning phase without any negative impacts on overall cow-calf production.

Download or read book Social Behavior in Farm Animals written by J. L. Keeling and published by CABI. This book was released on 2001 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: An understanding of social behaviour is increasingly necessary in farm animal husbandry as more animals are housed in groups rather than in individual stalls or pens. There may be economic or welfare reasons for such housing. This book is the first to specifically address this important subject. The chapters fall into three broad subject areas: concepts in social behaviour; species specific chapters; current issues. Authors include leading experts from Europe, North America, Australia and New Zealand.Animal welfare/behaviour issues are becoming increasingly importantCombines theoretical and practical details about the social behaviour of our most common farm speciesWritten by leading experts from around the world

Download or read book Beef Cattle Production Systems written by Andy D. Herring and published by CABI. This book was released on 2014-10-24 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook provides an integrated view of beef cattle production with a systems based approach, discussing the interrelationships of a broad range of aspects with the overall goal of optimising cattle production. This book provides the background to allow cattle producers to match their production environments with genetic, management, and marketing opportunities for sustainable beef production globally. This logic and resulting considerations can then be tailored to address specific regional challenges and opportunities worldwide. Considerations and examples for extreme situations will be provided, such as very small herds, very large herds, communal-group situations, and minimal artificial input systems.

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.
