Factors Affecting Calf Crop


Book Description

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.




Kansas Cow-calf Production Efficiency


Book Description

The beef cattle sector has been, and continues to be, the single largest sector in the Kansas agriculture industry, with cattle and calves generating $8.27 billion in cash receipts in 2017 (KDA 2018). In 2017, Kansas produced nearly 5.69 billion pounds of red meat, or nearly 11 percent of the nation's total (KDA 2018). According to estimates prepared by the Kansas Department of Agriculture, beef cattle farming and ranching has a direct output of approximately $6.3 billion. The cow-calf sector is the beginning of the beef industry; therefore, understanding the factors influencing profitability, efficiency, and structure is very important. The objective of this study is to examine the efficiency of beef cow-calf production in Kansas. Technical, allocative, and scale efficiencies of cow-calf operations are estimated, as well as, analysis on the relationship between input costs and efficiency and profitability and efficiency. Beef cow-calf operations vary considerably in size, available resources, profitability, and the use of technology. The variability in profitability suggests room to improve both production and financial management practices. In addition to estimating efficiency measures of cow-calf operations, the study identifies how marketing strategies (selling calves vs. selling feeders) impacts efficiency. This study contributes to the existing literature by estimating efficiencies for cow-calf producers and identifying production characteristics that impact efficiencies, in addition to, introducing the use of super-efficiency in the cow-calf industry segment. The nonparametric Data Envelopment Analysis approach, along with regression analysis, is used to determine how marketing strategies and production characteristics are correlated with efficiency and profitability. The Kansas Farm Management Association data are used in this analysis with cow-calf producers analyzed in two groups based on their marketing strategy (sells calves or sells feeders). Three years of whole-farm and enterprise data are included in the study, with a total of 240 producers selling calves and 264 producers selling feeders between 2018 and 2020. An input orientation is applied including feed, labor, utilities, and veterinary costs. Output is defined as the gross farm income (in dollars). Producers selling feeders were more technically efficient than those selling calves in both 2018 and 2019; however, in 2020, those that sold calves were slightly more technically efficient on average (0.840) than those that sell feeders (0.830). Technical efficiency was relatively more important than scale and allocative efficiency for both marketing strategies across almost all years (one exception in 2020, with producers marketing calves, where the allocative efficiency correlation coefficient was higher than technical). Technical efficiency was relatively more important in explaining profitability than either allocative or scale efficiency. Regressions indicated that a 0.10 increase in pure technical efficiency increases net income per cow by $96. A 0.10 increase in allocative and scale efficiencies increases net income per cow by $48 and $97, respectively. This suggests that producers that are experiencing low (or negative) levels of profitability should concentrate on adjusting the size of their herd relative to reducing input use per unit of output. Labor costs had the most impact on technical and allocative efficiency, while feed costs had the greatest impact on scale efficiency. Suggesting that producers wanting to impact their efficiency should focus on feed and labor costs.

Management Strategies for Sustainable Cattle Production in Southern Pastures


Book Description

Management Strategies for Sustainable Cattle Production in Southern Pastures is a practical resource for scientists, students, and stakeholders who want to understand the relationships between soil-plant interactions and pasture management strategies, and the resultant performance of cow-calf and stocker cattle. This book illustrates the importance of matching cattle breed types and plant hardiness zones to optimize cattle production from forages and pastures. It explains the biologic and economic implications of grazing management decisions made to improve sustainability of pastures and cattle production while being compliant with present and future environmental concerns and cattle welfare programs. Documents the effects of cattle grazing on greenhouse gas emissions and carbon footprints Discusses strategies to enhance soil fertility, soil health, and nutrient cycling in pastures Provides information on the use of stocking rates, stocking strategies and grazing systems to optimize cow-calf production of weaned calves and stockers. Presents innovations in cattle supplementation and watering systems to minimize negative impacts on water and soil health Includes methods for weed control to maintain pasture condition and ecosystem stability Describes management strategies to integrate cattle operations with wildlife sustainability
















Nutrient Requirements of Beef Cattle


Book Description

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.
