This book presents the chemical composition and nutritional values of the feed materials fed to farm species including pigs, poultry, ruminants and equine etc. Add to basket. The tables in this book present the chemical composition and nutritional values of the feed materials fed to the main farm species. The feed materials included in this publication are used both in the formulation of compound feeds and as straight feedstuffs concentrates and by-products.
Tables of composition and nutritional value of feed materials
The tables in this book present the chemical composition and nutritional values of the feed materials fed to the main farm species. The feed materials included in this publication are used both in the formulation of compound feeds and as straight feedstuffs concentrates and by-products. The values of chemical composition were mainly obtained using field data collected by AFZ from laboratories specialising in animal feeding the data base includes over one million values. The nutritional values result principally from experimental work performed by INRA and its partners. The data used take into account the evolution in feed materials and nutritional concepts. Important characteristics have been introduced, namely net energy for pigs growing pigs and sows , amino acid digestibility, mineral availability and starch degradability for ruminants. In the present context of animal feeding and the new challenges that it faces product quality and safety, animal health and welfare, environmental issues , this publication provides a reliable scientific reference document for feed manufacturers, veterinarians, extension officers, farmers, lecturers and students.

Net energy evaluation of feeds and determination of net energy requirements for pigs. Feeds for pigs can be attributed different energy values according to, first, the step considered in energy utilization DE: digestible energy, ME: metabolizable energy and NE: net energy and, second, the method used for estimation at each step. Reference methods for evaluating DE content are based on in vivo digestibility measurements; indirect estimates of DE values are obtained from in vitro methods or prediction equations based on chemical characteristics. Methods have also been proposed for estimating urinary energy and gas energy to a smaller extent in order to calculate ME content from DE value. The NE values originate from energy balance studies slaughter methods or, more commonly, indirect calorimetry measurements in respiration chambers and their compilation allows the calculation of NE prediction equations based on digestible nutrient contents or DE or ME contents. Such equations are applicable to both ingredients and compound feeds.

Tables of Composition and Nutritional Value of Feed Materials
Traditional feed composition tables have been a useful tool in the field of animal nutrition throughout the last 70 yr. The objective of this paper is to discuss the challenges and opportunities associated with creating large feed ingredient composition tables. This manuscript will focus on three topics discussed during the National Animal Nutrition Program NANP Symposium in ruminant and nonruminant nutrition carried out at the American Society of Animal Science Annual Meeting in Austin, TX, on July 11, , namely: 1 Using large datasets in feed composition tables and the importance of standard deviation in nutrient composition as well as different methods to obtain accurate standard deviation values, 2 Discussing the importance of fiber in animal nutrition and the evaluation of different methods to estimate fiber content of feeds, and 3 Description of novel feed sources, such as insects, algae, and single-cell protein, and challenges associated with the inclusion of such feeds in feed composition tables. Development of feed composition tables presents important challenges. For instance, large datasets provided by different sources tend to have errors and misclassifications.

Values calculated using the former INRA system are included as well. The nutritional makeup of feeds and what they contribute to beef cattle performance determine their true value Table 1.
Composition and nutritive values of feeds for cattle, sheep, goats, pigs, poultry, rabbits, horses and salmonids. With Feedinamics, calculate the feed values of your own ingredients using their chemical composition! Click here for a demo! They include values about more than feeds of plant and animal origin and mineral sources. Data are presented in list or table form, on as fed fresh and dry matter basis, and include statistics of variability. Ruminant values for energy, protein and minerals phosphorus, calcium are provided. Values calculated using the former INRA system are included as well.
