I. INTRODUCTION Papers have been presented at the past two APSS meetings on the subject of low protein diets (Kidd and Choct, 2017; Hilliar and Swick, 2018; Lambert and Corrent, 2018). Few, if any, have taken note of the economics of such diets. This paper is an examination of the costs of low protein diets. A brief history of amino acids is worth reviewing. Each time a limiting amino acid became available commercially, and was used, the protein level of broiler diets was...

1. Introduction Liquid feed has become a popular feeding system for pigs in many European countries. It consists of a blend compound feed (mixture of raw materials “as fed”) with water or liquid food-industry co-products, in a central tank in the pig unit, before delivery through a pump-and-pipes mechanical system [1,2]. Liquid feed contains about 700–800 g of water per kg, since the capacity of the pump-and-pipes devices determines the upper limit for dry...

1. Introduction Carotenoids are natural pigments which are responsible for yellow to red colour observed in plants and vegetables (Mortensen, 2006). Carotenoids are important for its various roles in human and animals, these include immune functions, decrease in the risk of disease and antioxidant function (Johnson, 2002; Rao & Honglei, 2002; Hinds et al., 1997). There are over 700 carotenoids (Junpatiw et al., 2013); one of which is the β-carotene. β-carotene can...

A balanced broiler chicken diet requires essential (EAA) and non-essential (NEAA) amino acids to attain maximum growth. However, the optimal ratio of these two dietary AA groups may change with different growth rates but this is not fully understood (Heger, 2003). In addition, commercial broiler feeds are formulated based on average flock requirements of EAA, hence neglecting NEAA ratios and potential individual variations. Consequently, it is expected that commercial broiler diets for...

Dietary energy available to animals is key to formulating feed as it is required for all aspects of animal life. In poultry, apparent (AME) and true (TME) metabolisable energy (ME) values have been developed for feed formulation with or without correction for nitrogen balance. Over the past 50 years, the accuracy of ME systems has been an ongoing debate and the data produced from different bioassays have been found not to be comparable (Farrell, 1999). Overall, the ingredient matrix ME...

Let's Squawk About It is a monthly interview segment by the Poultry Science Association. The COVID-19 Pandemic has changed many aspects of life, but how about for a chicken? Roy Brister, of Tyson Foods, shares some insight on how feed formulation had to change due to a domino effect brought on by the pandemic....

with the high cost of corn, soybean meal and yellow grease, we can use alternative sources of energy and protein, for example, broken rice, sorghum, wheat, pasta meal , bakery meal, whole soybean meal, poultry by-products , meat and bone meal, DDGS. These ingredients can help reduce costs without affecting the performance of our animals, in small amounts can be used cassava and sweet potato meal , also the wheat bran and rice. ...

INTRODUCTION The nonstarch polysaccharide (NSP) portion of corn and soybean meal (SBM) – the 2 primary ingredients in North American poultry feeds – is complex and varies considerably across both ingredients. Exogenous NSP enzymes are supplemented to improve the digestibility of this fiber fraction for which no enzymes are secreted endogenously (Bedford, 1995; Cowieson, 2010; Kiarie et al., 2013). In this regard, diets composed mainly of...

The North America specialty animal feed additives market is projected to accrue sizable revenue growth on account of rapid expansion activities in the eggs and meat industry. Animal feed additives are preparations or substances that are added for enhancing feed quality and boosting animal nutrition.
Major regulatory organizations like the U.S. FDA are classifying animal feed additives under the Generally Recognized as Safe (GRAS) category. This makes them safe for human and animal...

For several decades, Insta-Pro International has been well known around the world for dry extrusion, which we invented in the 1960’s.Dry extrusion was invented to process soybeans, and over the years, this process has been well researched. The advantages of this technique are the following: Thorough plant cell wall rupture, providing much improved access to nutrients Deactivation of naturally-present antinutritional factors, which hinder animal...

Introduction Over the years, animal nutritionists have developed alterations in the quality of diets intended for broilers aiming to increasingly adapt these diets to meet the nutritional requirements of these birds. Studies on the protein nutrition of broilers have considered the use of digestible amino acids in the formulation of diets, which makes it possible to reduce the amount of dietary protein and improve the adjustment between amino acids, thus contributing to...

DESCRIPTION OF PROBLEM Phytase has been regularly incorporated into commercial poultry diets due to its relatively low cost and effectiveness at hydrolyzing phytate (IP6; myo-inositol 1, 2, 3, 4, 5, 6-hexakis dihydrogen phosphate; Bedford and Cowieson, 2009). Dephosphorylation through phytase supplementation is needed for birds to access this source of P and also to prevent the chelation of IP6 with other nutrients such as amino acids and minerals (Nelson, 1967; Ravindran et...

1. Introduction Maize is the most common energy source used in commercial monogastric diets, especially in the American, Southern Europe and most Asian countries where maize grain is the primary cereal for poultry feeds (Dei, 2017). However, the nutritional value of maize for livestock feeding can vary (Cowieson, 2005). Genotype, agronomic conditions and pre- and post-harvest processing can affect the chemical characteristics of cereal grains (Gehring et al., 2013). Indeed...

Introduction Much information is given ( Willem Van Cotthem, 2012 ) about Opuntia ficus-indica as an aloes. Therefore, the aim of the present study was evaluating the possibility of using powders of either fruits' skins or leaves of the Egyptian Teen Shoky as replacers for dietary corn in all-males mono-sex Nile tilapia, Oreochromis niloticus diets and their effects on fish performance for 75 days. This is an attempt to ameliorate feed costs by...

INTRODUCTION Minerals are needed for all normal life processes and the physiological importance of minerals for farm animals, including poultry, is well documented (Spears, 1999; Underwood and Suttle, 1999). Recommendations for mineral requirements of poultry are available (NRC, 1994), but these are based on research with older strains and are inadequate and outdated for modern strains of poultry (Leeson, 2005). Despite the biological and economic importance, published data on...
