Introduction Dairy farmers might be over-feeding a large proportion of lactating cows when they feed the same ration to a large group of animals. Diets are normally formulated to provide enough nutrients to the most productive animals, which in turn gives extra nutrients to the less productive animals. Therefore, splitting lactating cows in smaller groups and offering group-specific feeding rations provides more precise...
I. THE GEOMETRY OF NUTRITION
In GF models, individual animals, foods and their interactions are represented graphically in a geometric space defined by two or more food components (for a comprehensive review see Simpson and Raubenheimer, 2012). Foods are represented as vectors through nutrient space at angles determined by the balance of the component nutrients they contain (nutritional rails), and the animal's nutritional state as a...
INTRODUCTION The interest in search for alternative/additional feed ingredients is of paramount importance in developing countries, mainly, because of the acute shortage of traditional feed materials. Introduction of saline agriculture production systems in salt affected regions has proved to be an effective way to save fresh water for human and animal consumption while the saline water could be used for animal feed...
Abstract
Thirty Awassi lambs were used (5-6 months of age) and26.02 Kgaverage body weight, they were randomly allocated into six groups. The animals were fed group feeding (3% of body weight) six ration of different sources (ground corn cobs, date stones or date pulp) which was supplemented with 2 kg of Saccharomyces cerevisiae (Sc) and 1kg Iraqi probiotic(Ip) as a pellets ration. Barley straw...
Enzymes are now widely used in animal feed. Various key reasons justify their use. Firstly, enzymes inhibit the action of anti-nutritional factors in the feed, which have an adverse effect on both the animal's digestive system and health. Secondly, enzymes improve access to the nutrients in the feed. Lastly, enzymes compensate for the lack of natural enzymes capable of breaking chemical bonds as well as the lack of enzymes in the undeveloped...
Challenges and opportunities facing the international feed/food industry have never been greater than those faced by these industries today. It has become apparent that anything less than a very proactive approach to addressing current challenges may not be sufficient. Current international events are leading feed companies to attempt to move from a traditional role as a ‘feed company’ to becoming an integral part of the ‘Food Supply Chain’. This is driven essentially by the fact that...
It is an uncontested fact that feed nutrients are bio converted into animal products through the animal system. The conversion process depends on various factors. The genetic frame of the animal enables the conversion pragmatic; however the conversion efficiency of the feeds has a vital role in the process. Often it is alleged the fact that dairy cow is a poor converter of the feed nutrients to milk. The complex structure of digestive system in a cow causes...
A breakthrough in our understanding of phytase enzyme mode of action and the associated matrix values in feed formulation has been provided in a recent paper published by Tran et al. in the January 2011 edition of Analytical Biochemistry entitled 'A simple and fast kinetic assay for phytases using phytic acid–protein complex as substrate'. While at first glance the relevance of the title to animal nutritionists may not be immediately...
Introduction Genetic evolution of production animals and the increase of food demand have required high quality and digestibility products for animal feeds use. In Brazil, especially in Paraná State, soybean has been given prominence in relation to other cultures due to sale price rises and the knowledge and adoption of production techniques (GOLDFLUS, 2001). Glycine max (L.) Merril soybean belongs to the legume...

A recent trial conducted in Brazil on pigs aged between 49 and 144 days confirms that including Rovabio ® Max, Adisseo’s multi enzymatic product in a corn-based diet improves the average daily gain, feed conversion and carcass quality of the pigs. Enzyme supplementation is efficient in reducing costs, by lowering nutrient content of the corn-soybean diets without compromising performance. The use of...
Rising costs of raw materials increases the demand for product optimization and yields. Now, the means of accurately controlling the moisture content within a batch flow process has been finally breached within industry. DSL Systems Ltd has teamed up with Intelscan to provide moisture measurement and control as an extra in the AutoPilot4Feed package. Several designs utilising microwave technology as a means to measure moisture are currently under trial with different...
Hi, i live in the Dominican Republic and I am starting to feed bulls in my farm which are 100% locked in one place. I´m planning to feed them with sugar cane and king grass, for the protein I am going to use urea. If you have any suggestions, grains in my country are very expensive for animal use. I need to get a 200kg gain in about 6-8 month. I would like to know if it´s posible to achieve it with what I am using or what else should I use....

ABSTRACT The primary objectives of this research were to measure total and phytic phosphorus (P) in a range of ingredients and to establish prediction model using near infrared spectroscopy (NIRS). A total of 227 ingredient samples was collected worldwide during one year and most of the sampled ingredients were cereals, cereal byproducts, oilseeds and oilseed meals. All of the samples were analyzed for their total and phytic...
Haylage is prepared out of green forage to preserve it for long time. It is prepared by leaving the green forage cut on the field to dry its moisture level to 55 and baled out to store. In some cases it is packed in air tight packs so that its freshness will be maintained. In order to densify to reduce the volume hydraulic press is used. Such densified bales are packed air tight. There si no advantage of enhancing the nutritive value in such preparations. Therefore, a new feed technology is...
The various ways in which human food is produced are vigorously discussed and questioned in modern societies. We expect food from plants, farm animals and microorganisms to be of good quality, healthy and inexpensive. Furthermore the food industry and politicians are increasingly concerned about environmental matters and keeping energy inputs low. In addition, arguments for food produced as naturally as possible are increasingly heard from organic...
