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 2016 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two experiments were conducted to determine the influence of increased nutrient intake on beef heifer performance and reproductive efficiency. Experiment 1 evaluated the effect of heifer development supplementation regimen on heifer performance and reproduction during the pre- and post-breeding period. Heifers were developed grazing native range and supplemented to achieve 1) a constant rate of gain (CG) or 2) low rate of gain for the first half of development period followed by a high rate of gain for the remaining half of the development period (LoHi). Heifer performance was similar over the development period, with supplementation regimen having no effect on reproductive performance between treatments. Feed costs and costs to develop 1 pregnant heifer was decreased for LoHi heifer compared to CG heifers due to supplementation strategy. Following breeding heifers were stratified and randomly assigned to graze native pasture and supplemented at a low (CON) or high (High) rate for 30 d. CON heifer had a trend for increased AI pregnancy rate compared to High heifers, indicating a potential influence of nutrition on reproductive success. Accurately predicting forage nutrient composition during Exp. 1 impacted performance, altering predicted gains. In Exp. 2 heifers were individually fed a silage based diet to imitate treatments and predicted gains from Exp. 1. Heifer BW was similar among treatments over the development period. Although total ADG was similar among both treatment, ADG and intake was increased for CG heifers during the first 45 d, while LoHi heifer ADG and intake was increased over the last 45 d of the development period. Feed efficiency increased for LoHi heifers and decreased for CG heifers over the treatment period, indicating a potential compensatory gain effect. Reproductive traits measured were not impacted by development strategy; however, additional research is warranted to fully understand the impact of increased nutrient intake and compensatory gain on metabolic hormones, oocyte competence, and follicular microenvironment. In summary, these experiments provided further evidence of the impact of nutrition on reproductive performance, with future research warranted specifically investigating follicular fluid metabolic hormone concentrations and gene expression in oocytes and granulosa cells, and their impact on reproductive success.

This book was released on 2016-06-16 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since 1944, the National Research Council (NRC) has published seven editions of the Nutrient Requirements of Beef Cattle. This reference has guided nutritionists and other professionals in academia and the cattle and feed industries in developing and implementing nutritional and feeding programs for beef cattle. The cattle industry has undergone considerable changes since the seventh revised edition was published in 2000 and some of the requirements and recommendations set forth at that time are no longer relevant or appropriate. The eighth revised edition of the Nutrient Requirements of Beef Cattle builds on the previous editions. A great deal of new research has been published during the past 14 years and there is a large amount of new information for many nutrients. In addition to a thorough and current evaluation of the literature on the energy and nutrient requirements of beef in all stages of life, this volume includes new information about phosphorus and sulfur contents; a review of nutritional and feeding strategies to minimize nutrient losses in manure and reduce greenhouse gas production; a discussion of the effect of feeding on the nutritional quality and food safety of beef; new information about nutrient metabolism and utilization; new information on feed additives that alter rumen metabolism and postabsorptive metabolism; and future areas of needed research. The tables of feed ingredient composition are significantly updated. Nutrient Requirements of Beef Cattle represents a comprehensive review of the most recent information available on beef cattle nutrition and ingredient composition that will allow efficient, profitable, and environmentally conscious beef production.

Download or read book The Effects of Pre and Postweaning Nutrition on Fertility and Feed Efficiency in Beef Heifers written by Maggie K. Bloomsburg and published by . This book was released on 2018 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cattle in the Pacific Northwest graze a variety of forages which vary in quality. The effects of forage quality on heifer reproductive development and fertility is still under investigation. Therefore, the first objective was to investigate the effects of grazing different quality forages preweaning and postweaning on reproductive traits and feed efficiency in heifers. Although nutritional differences were present, pre- and postweaning treatments did not affect reproduction. This indicates different qualities of forage present in Idaho may be utilized for heifers. Feed costs represent a large portion of cattle producers' expenses. Selecting for feed efficiency allows producers to capitalize on these expenses. However, the effects of selecting for efficiency on reproduction is still undetermined. The second objective was to study the relationship between feed efficiency and reproductive development and fertility. No differences in reproductive traits were detected among heifers ranked as efficient, average or inefficient at utilizing feed for growth.
