Book Description
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.

Book Description
Recent Advances in Animal Nutrition-1981 is a collection of papers that discusses the effects of dietary fat on milk composition, relating it to the biochemistry of fat synthesis in the mammary gland. The influence of concentrates on milk composition as well as the pattern and level of concentrate feeding on milk output are also covered. The book describes the need for better utilization of grass and grass products in dairy production, the mineral and trace element requirements of pigs; the importance of anion-cation balance in poultry diets and its effects on performance levels; and the selenium and cobalt requirements of ruminants. The problems of medicinal residues in animal products and the toxicological effects of aflatoxin residues in animal products are also considered. People involved in agriculture, dairy production and animal nutrition will find the book useful.

Book Description
On the basis of a comprehensive literature review and analysis, Nutrition During Lactation points out specific directions for needed research in understanding the relationship between the nutrition of healthy mothers and the outcomes of lactation. Of widest interest are the committee's clear-cut recommendations for mothers and health care providers. The volume presents data on who among U.S. mothers is breastfeeding, a critical evaluation of methods for assessing the nutritional status of lactating women, and an analysis of how to relate the mother's nutrition to the volume and composition of the milk. Available data on the links between a mother's nutrition and the nutrition and growth of her infant and current information on the risk of transmission through breastfeeding of allergic diseases, environmental toxins, and certain viruses (including the HIV virus) are included. Nutrition During Lactation also studies the effects of maternal cigarette smoking, drug use, and alcohol consumption.

Book Description
Recent Developments in Ruminant Nutrition presents papers that discuss the advancement of the different areas of ruminant nutrition. The book is comprised of 20 chapters that cover topics, such as reproduction, diet, and nutrition. The coverage of the text includes growth stimulation in ruminants; protein quantity and quality for the U.K. dairy cow; and complete-diet feeding of dairy cows. The book also covers rumen fermentation related topics, such as influence of nitrogen and carbohydrate inputs on rumen fermentation; aspects of the biochemistry of rumen fermentation and their implication in ruminant productivity; and manipulation of rumen fermentation. The text will be of great use to researchers and professionals in the animal husbandry industry.

Book Description
ABSTRACT: Four experiments were conducted to evaluate the effect of adding biological additives to the diet or feeds of lactating dairy cows on their performance or the quality of the feeds or diets. The objective of Experiment 1 was to determine the effect of dietary addition of a fibrolytic enzyme preparation containing cellulase, xylanase and esterase activities on the performance of dairy cows fed low or high - concentrate diets. Sixty lactating Holstein cows in early lactation (22 + 3 days in milk) were assigned to the following treatments: 1) Low concentrate (33%) diet (LC); 2) LC plus enzyme (LCE); 3) High concentrate (48%) diet (HC); 4) HC plus enzyme (HCE). The enzyme was sprayed at a rate of 3.4 mg/g of dry matter (DM) on the total mixed ration (TMR) daily for 63 d. The first 14 d were used for adaptation to diets and the last 49 d for measurements. In addition, four ruminally-fistulated cows were used to determine dietary treatment effects on indices of ruminal fermentation and in situ DM degradation in the rumen. Enzyme application did not affect milk yield or intake of DM, but increased digestibility of DM, CP, NDF, and ADF, and increased the efficiency of milk production. Increasing the concentrate level reduced ruminal pH but increased intakes of DM and CP, digestibility of DM (DMD) and CP, and milk yield and milk protein yield.
