Available in PDF, EPUB and Kindle. Book excerpt: The increasing demand for high-quality beef has led to the necessity of including higher levels of cereal grains and its by-products into cattle diets. In this context, adequate nutrition of beef cattle involves knowledge of energy and nutrient requirements to define specific nutritional strategy. The evolution feeding strategies to feedlot cattle depends on advances related to ruminant metabolism, as well as to the ruminal microbiota. Furthermore, a continuous flow of knowledge development in feedlot cattle nutrition and metabolism is important, as new feeds, additives, or even new management approaches come up very often, and new scenarios will impact protein and energy metabolism, the ruminal microbiota, and also strategies to modulate ruminal fermentation to improve health and performance of feedlot cattle. Overall, the main goal of this Research Topic is to contribute with recent advances in feedlot cattle nutrition and metabolism, addressing studies related to the nutrition of high-performing ruminants, with a special emphasis on the feed efficiency, ruminal fermentation and animal performance. Furthermore, we are interested in different aspects of sustainability and efficiency. In other words, the goal is to attract studies that address such issues, both from a general perspective and in relation to specific domains. Hence, the integration of existing and current knowledge will help refine strategies to optimize the performance of feedlot cattle.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective was to evaluate the effects of tilmicosin fed to high-risk cattle for 14 consecutive days, with or without a live-yeast probiotic blend, during the 42-d study period. In Exp. 1, auction-derived bull (n = 59) and steer (n = 31) calves (initial BW = 220.3 ± 3.2 kg) were randomly assigned to 1 of 3 treatments (3 pens per treatment, 10 animals per pen) consisting of: 1) positive control (TUL) received ground corn top-dress as placebo and injectable tulathromycin on d 0, 2) Tilmovet (TV) received a tilmicosin supplemented diet (0.663 mg/animal/d) from d 0 to 14, and 3) TV with a proprietary live-yeast probiotic blend (TV+; 10 g/animal/d; OptiSafBeef, Phileo, Milwaukee, WI) for the duration of the study. The animals in the TUL group had a 7-d post metaphylactic interval (PMI) because they received injectable tulathromycin at d 0, whereas cattle in the TV and TV+ were eligible to be treated for BRD following 3-d post initial treatment of tilmicosin supplemented in the diet. The TUL group had greater ADG during the first 14-d (P = 0.02) and tended to be heavier than TV and TV+ on d 28 (P = 0.06). Overall (d 0 to 42), TV+ had greater (P = 0.02) G:F than TUL and TV. Overall DMI (P = 0.01) for the TUL group from d 0 to 42 was greater compared to TV and TV+. In Exp. 2, auction-derived bull (n = 68) and steer (n = 22) calves (initial BW = 219.4 ± 2.97 kg) were randomly assigned to treatment pens consisting of: 1) control (TUL) that received ground corn top-dress placebo, 2) Tilmovet (TV) that received a tilmicosin-treated diet (0.663 mg/animal/d) from d 14 to 28, and 3) TV with ground corn top-dress containing a live-yeast probiotic (10 g/animal/d; OptiSafBeef; TV+) for the duration of the study (Fig. 2.7). All treatments were administered ceftiofur on d 0 with a 3-d PMI. Final BW did not differ (P = 0.70). Total starch digestion had a day effect over the 2 collection days (P = 0.02), and a tendency (P = 0.09) was observed for apparent starch digestion to be greater for TUL on d 0. Performance and health outcomes were improved with the administration of injectable tulathromycin in Exp. 1, but there were no health differences and few performance effects noted in Exp. 2. Results indicate oral tilmicosin should not be the primary metaphylactic treatment method in high-risk beef cattle. Delaying oral tilmicosin for 14-d following an injectable antimicrobial slightly improved performance and health, but further research with larger pen replication needs to be conducted.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is to provide the reader with some basic information applicable to cattle feeding. It is intended to adapt some of the basic principles of nutrition in applied form. During the past few decades there have been various changes in type and form of feeds available for livestock feeding due to new kinds of equipment. Mechanization has made it possible to perform certain opera tions of the beef production program more efficiently and economically. With all the new innovations and advances in animal nutrition combined with the capabilities of the computer, it becomes very challenging for everyone to keep up to date on the latest information in the field of cattle feeding and production. The text was written with the intent of utilizing the raw materials, facilities, equipment, etc. which are available in the United States. The terminology of certain materials such as feed ingredients will vary from one country to another. One term which is frequently used in this text is forage. Although the term roughage is used more commonly in the United States it has been replaced with forage in this text. J.K.

Available in PDF, EPUB and Kindle. Book excerpt: Three experiments were conducted to examine nutritional and management strategies for different segments of the beef industry. The first experiment examined the effects of feeding traditional step-up diets (STEP) vs. limit-feeding (LIMIT) the finishing diet to adapt cattle to high-concentrate diets. When all cattle reached ad libitum intake of the finishing diet there was a trend (P = 0.09) for DMI to be different between treatments. During week 1, STEP cattle had higher total VFA concentrations (P = 0.02), while LIMIT cattle had higher valerate absorption (P = 0.02) and disappearance (P = 0.08). During week 4, LIMIT cattle had higher total VFA concentrations (P = 0.03) and lower valerate disappearance and absorption (P = 0.05) than STEP cattle. These results indicate that limit-feeding the finishing diet may inhibit nutrient absorption from the rumen or this method may cause increased production of valerate by lactate utilizing bacteria due to a more acidotic rumen environment. The second experiment examined the effects of feeding 5% (DM basis) dried, full-fat corn germ (GERM) on feedlot performance and carcass characteristics of naturally raised yearling steers and heifers. Carcass-adjusted ADG was higher for GERM cattle (P = 0.04). There were no other differences in performance or carcass characteristics. Total incidence of liver abscesses and the incidence of severe liver abscesses were decreased by 12 and 8.2% (P = 0.01 and 0.02, respectively) when GERM was added to the diet. Corn germ can be added to finishing diets at 5% without affecting performance and carcass characteristics. Producers raising natural cattle may also be able to benefit from the reduced incidence of liver abscesses. The third experiment examined concurrent metaphylactic treatment of high-risk calves with tulathromycin and chlortetracycline. Calves were placed on 1 of 3 treatments: 1) no top-dress pellets; 2) diet top-dressed with pellets containing chlortetracycline; or 3) diet top-dressed with pellets containing no chlortetracycline. There were no differences in the performance or health of these calves (P> 0.25). There are no additive benefits of concurrent metaphylaxis using both tulathromycin and chlortetracycline. This information could assist producers when designing receiving health protocols for high-risk calves.

Available in PDF, EPUB and Kindle. Book excerpt: Beef markets in the U.S. are rapidly changing as alternative production systems and technologies evolve in response to consumer demands and compete with conventional grain-fed beef production. Beef produced through distinguishable systems results in products with different marketable attributes that may attract price premiums, for ex., claims relating to input and other resource use, environental impacts, animal welfare, slaughter/processing infrastructure and efficiencies, and providing continuous supplies of safe products. Markets are rapidly changing as consumers demand various combinations of these attributes in their beef products and as science and consumer knowledge converge. This report explores the market outlook implications of these changes by examining the specific production technologies behind alternative production systems and products. Figures and tables. This is a print on demand report.

This book was released on 1991 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: This bulletin analyzes economic impacts of alternative growth promotant strategies on the United States (U.S.) beef industry at the cow/calf, stocker, feedlot, wholesale, and retail levels. Production scenarios included implanting at each production level, never implanting, implanting at the cow / calf level only, implanting at the cow / calf and stocker levels, implanting at the feedlot level only, and implanting at the stocker and feedlot levels. The production scenarios were evaluated for the same number of days on feed and feeding to the same slaughter weight. Estimates of the physical effects of alternative implant strategies were obtained by use of the Beef Cattle Growth Model developed at Texas A&M University. Information developed by the model included live, carcass, and retail product weights, carcass fat percentages, feed consumed, and estimated U.S. yield and quality grades by alternative implant scenarios. The study also provides estimates of changes in net returns to producers and cattle feeders and in wholesale and retail gross revenues as implant strategies undergo change.

This book was released on 2021-04-23 with total page 535 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the scientific contributions published within the Animals topical collection “Feeding Strategies to Improve Sustainability and Welfare in Animal Production”. Originally a Special Issue, it has turned into a permanent collection, with its first article being published in July 2019 and more than 30 published articles a year later: evidence of the great interest from the scientific community regarding the topics addressed. The articles, which are grouped by species (poultry, ruminants, pigs, etc.) and by topic, deal with a wide range of arguments that, first of all, highlight the extraordinary complexity and diversity that exists in the animal production sector, and then, the great influence that nutrition and feeding can have in terms of optimizing the use of environmental resources and improving the welfare of farmed animals. In addition, all this is closely connected with the urgent need to safeguard the resources of the planet on which we live.

This book was released on 2003-04-07 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Air Emissions from Animal Feeding Operations: Current Knowledge, Future Needs discusses the need for the U.S. Environmental Protection Agency to implement a new method for estimating the amount of ammonia, nitrous oxide, methane, and other pollutants emitted from livestock and poultry farms, and for determining how these emissions are dispersed in the atmosphere. The committee calls for the EPA and the U.S. Department of Agriculture to establish a joint council to coordinate and oversee short - and long-term research to estimate emissions from animal feeding operations accurately and to develop mitigation strategies. Their recommendation was for the joint council to focus its efforts first on those pollutants that pose the greatest risk to the environment and public health.
