Beef Cattle Feeding and Nutrition is the third in a series of books on animal feeding and nutrition. These books are designed to keep readers abreast of the rapid developments in feeding and nutrition. These developments have resulted in changes in diets, the use of new feed processing methods, improved use of by-product feeds, and more supplementation with minerals, vitamins, amino acids, and nonprotein nitrogen compounds. The book is organized into four parts. Part I focuses on the nutrient requirements of beef cattle. Beginning with a review of rumen physiology and energy requirements, the remaining chapters discuss the vitamin, mineral, and protein, requirements of beef cattle. Part II on feedingstuffs includes studies on pasture and other forages; hay and haylage making; silage and crops for silage; and concentrates for beef cattle. Part III includes studies on breeding herd nutrition and management; and milk production and calf performance. Part IV on cattle finishing covers cattle finishing systems; feedlot disease; and economics of cattle feeding.

This book presents strategies for feeding energy and protein supplements to pasture-fed dairy cows and examines the potential economic benefits. Effective supplementary feeding of concentrates is critical to the success of all dairy farms. This book is a substantially revised edition of 'Feeding Concentrates: Supplements for Dairy Cows' DRDC 1993. It focuses on feeding concentrates to pasture fed cows to achieve high milk production per cow per hectare, and will assist farmers to decide which supplements give the best results in their particular situation. The benefits that arise from supplementary feeding include higher stocking rates, promotion of growth in heifers and young cows; better body condition score and increased lactation length when pasture is less available; improved pasture use; reduced cost per tonne of pasture eaten; flexibility to increase milk production when milk prices are high; and increased milk protein content when the energy content in pasture is low. This edition has thoroughly reviewed the issues and clearly documents the results of research particularly for grains supplementation. The summaries and recommendations in each chapter will be particularly helpful to dairy farmers in making best management decisions relating to concentrate feeding.

The modern dairy cow is amazingly efficient, as most of the cows energy is put into milk synthesis versus muscle deposition. It is quite obvious that within the past 50 years, the United States has made tremendous gains in managing cows for increased productivity, and as a result increased feed efficiency. However, despite remarkable advances in productivity, rising feed costs remain a threat to American farmers profitability, hence why feed efficiency is becoming a highlighted area of interest for dairy cattle. Although greater production of milk per cow has allowed for a reduction in feed costs, feed efficiency advances must continue to meet the demands of an ever-growing population. Advances in feed efficiency could lead to increased profitability and environmental stability. This thesis aims to enhance the understanding of feed efficiency by identifying factors that affect feed digestibility in Holstein cattle. The objectives of this thesis are to determine: how time of day effects estimates of feed digestibility; whether grinding size of fecal samples effects results; if results are repeatable within the same cow; and how feed digestibility is related to stage of lactation, milk yield, body weight, and genetic merit for feed utilization and other traits. Fecal samples were collected from 115 Holstein cows to determine total tract digestibility of DM and NDF. Feed digestibility measures were correlated with phenotypic covariables of interest and estimates of genetic merit. The significant factors associated with lower feed digestibility were milk yield and protein yield; MUN, fat percent and higher DIM were associated with greater feed digestibility. Likewise, higher genetic merit for yield was associated with reduced feed digestibility, whereas higher genetic merit for fat percentage was associated with greater feed digestibility. The most significant result of this study is that selection for higher yield has likely compromised total tract digestibility of NDF to some extent.

With new "World Markets" opening, the challenge to boost the Production efficiency of livestock products is increasing. The cost of feeding accounts for the largest single input in a production operation, thus, there is a need for a better understanding of nutrition and feeding. Written to appeal to both experts and beginners in the field, this new edition provides the reader with an understanding of the principles relating to livestock feeding. Parts I and II cover everything from nutrients, feedstuffs, minerals, vitamins, and additives to feed preparation/processing and ration formulation. Part III provides detailed information on different livestock species, such as, swine, poultry, dairy cows, beef cows and cattle. Domesticated species, such as horses, sheep, goats, dogs, cats, and rabbits are covered in Part IV Each species chapter discusses the management and feeding practices unique to that particular species. Feedstuff characteristics and nutrient guidelines are given for various classes of the species in the Appendix Tables. Advances in genetics, changes in scientific knowledge, food security, and concerns about the environment are just a few of the areas that have had an impact on livestock production. Because of these changes, it is essential that individuals and companies understand the effect feeding and management of livestock have on livestock production systems. Kellems and Church's "Livestock Feeds and Feeding, 5th edition, " provides the basis for this understanding and is a handy reference for anyone involved in livestock production.

Not illustrated. 1919 edition. Excerpt: ...finds protein feeds becoming higher in price, making the raising of legumes the more advisable. As an illustration of the feeding value of legumes, it may be said that most of them are nearly equal ton for ton to bran, which today is so well recognized as a standard foodstuff for farm animals that the demand can hardly be supplied, even though the price has continually raised until now it sells for from $22 to $29 per ton. Four tons of leguminous hay is not an exceptional annual yield for an acre, and compared with bran at prevailing prices the money value of a season's crop can easily be estimated. Add to the estimate the richness that has been added to the soil by the legumes having grown there, and every thoughtful dairyman will put forth his best efforts to grow one or more of these nitrogen-gathering plants in the future. No dairyman who does not make use of these plants in his farming and feeding operations is taking full advantage of the opportunities at his disposal. A combination of corn silage, leguminous hay and good cows is one that cannot be equaled otherwise. Nearly every state experiment station has performed experiments that have shown conclusively the value of these crops as compared with non-leguminous grasses. Although each year finds a great increase in the acreage of legumes grown in all parts of the United States, they are not being grown as largely as they should be, and millions of acres where timothy and non-leguminous grasses are now growing should be converted into protein-producing areas to furnish the balancing power for the carbonaceous grains, such as corn, barley, kafir corn and other crops, that are so largely and necessarily raised. The chief reason no doubt, that the nitrogen-gathering plants are not...
