A new educational program, hosted by the American Feed Industry Association (AFIA), will focus on biosecurity preparedness in the animal food industry. The program, “ Biosecurity: Preparedness Must Be Perpetual ,” will take place on Jan. 25, 2023, in conjunction with the 2023 International Production & Processing Expo, taking place Jan. 24-26 in Atlanta,...

1. INTRODUCTION Global programs are involved in addressing food and nutrition in the developing countries (WHO 2018). Improving nutrition is undoubtedly a challenging interdisciplinary proposition that involves availability and consumption of nutritious food. Covid-19 pandemic has further exposed the vulnerability of food systems in the low- and middle-income countries (LMICs). Green revolution was one milestone towards achieving food security when high yielding crop...

Introduction The processing of food grains into flour, vegetable oil, alcohol and biofuels offloads quantitatively variable, chemically diverse non-starch polysaccharides (NSP) into co-products (Bach Knudsen, 2014). Rapidly increasing human demand and random adverse climate change-related events are disrupting global grain markets, forcing producers into greater dependency on co-products for sustainable, cost-effective pig feeding strategies. Chemical and quantitative...

1. Introduction In Uganda, maize (Zea mays L.) is one of the most important crops in terms of production, consumption, and income generation. Because of its relevance, maize was one of the food security crops–and the only cereal–selected by the Ministry of Animal Industry and Fisheries of Uganda to implement a 5-year, multi-million USD agricultural intervention as part of the Development Strategy and Investment Plan (DSIP) during 2010–2015 (MAAIF, 2010). The...

Introduction Piglet post-weaning diets are by far the most expensive diets in the swine industry, mainly due to the need to reduce Post-Weaning Diarrhea (PWD) and optimize growth performance by including highly digestible feed ingredients with low content of antinutritive factors. It would therefore be economically advantageous, if some of the expensive protein sources that are generally considered necessary in diets for newly weaned piglets could be substituted with soy bean...

Introduction Soybean meal (SBM) is the most important and preferred source of quality protein in animal feeds (Banaszkiewicz, 2011). Among the oil seeds, SBM contains the highest crude protein (CP) and has the best AA profile, with only 6% crude fibre (Dei, 2011). The AAs in SBM are highly digestible by poultry (Newkirk, 2010). Based on the CP content, SBM can generally be classified as high protein (47% - 50%), or low protein (44% - 46%). Popescu & Criste (2003) suggested...

Introduction Feed cost represents 70% of the total cost of poultry and pork production (Patience et al., 2015); therefore, a number of processing techniques have been developed to maximize utilization of nutrients in feed ingredients and diets for optimum animal growth performance. Oilseed meals are commonly exposed to varying degrees of heat to remove solvents used during oil extraction, increase nutrient digestibility, improve storage life, and to reduce anti-nutritional...

INTRODUCTION The rangelands in the Southern Sinai are generally identified as an open shrub vegetation characterized by spare, slightly stands and semishrubs. The Chenopodiaceae family is the most widespread family as it has an interesting geographical distribution in Egypt as well as numerous countries all over the world. The native natural vegetation varies greatly in their species, varieties, productivity, chemical composition and nutritive value from location to another...

INTRODUCTION Goats are very important to the world’s food security and supply because of their ability to utilize fibrous materials not of immediate nutritional value to people. Feed accounts for about 70% of the cost of the livestock production, approximately one-half of the production cost for ruminants is in feed used for body weight and maintenance requirements. However, one of the most important factors affecting the energy requirement for maintenance (ME m )...

INTRODUCTION It has been well known that branched-chain amino acids (BCAA) (Val, Leu and Ile) are not only substrates for building block protein but they are also involved in intracellular signaling pathways on protein anabolism and stimulatory effects on protein synthesis. Among the 3 BCAA, Leu has been considered most effective in stimulating muscle protein synthesis by modulating the activation of mechanistic target of rapamycin (mTOR) and its downstream effectors, ribosomal...

Non-starch polysaccharides (NSP) have a considerable impact on digestibility in broilers, dictating nutrient availability and energy utilization. The high NSP content of the hulls in canola meal are one factor limiting its effective use in poultry diets. The major NSP present in canola meal include cellulose, pectic polysaccharides and a variety of non-cellulosic polysaccharides, including arabinoxylans (AX). Attempts have been made to increase utilization of canola meal through the use of...

The Problem Gut and oviduct microbiota are closely related, especially because of the common connection with the cloaca. In this condition, modulating the gut microbiota with multi-strain probiotic supplementation may change the oviduct tract microbiota. How we investigated or researched the problem Hyline W36 laying hens housed in commercial aviaries were evaluated. Control animals were fed the farm’s conventional diet. The 2nd treatment received the...

1. Introduction Aflatoxin M1 (AFM1) is the main metabolite of Aflatoxin B1 (AFB1), which is one of the four most common variants of Aflatoxins (AFs) [1–6]. There is sufficient evidence for the carcinogenicity of AFM1 alone or mixed with AFB1 and Aflatoxin G1 (AFG1) [7], although of lower potency than AFB1 [8,9]. When cattle ingest food or feed contaminated by AFs, it is estimated that up to 6.2 % of the content of AFB1 is transformed into AFM1 and excreted in milk...

Overview Renewed interest, especially in the United States, has sparked in assessing branched-chain amino acid interactions in practical diets for broilers. Indeed, as L-valine enters formulation bird nitrogen excesses are reduced as diet protein falls to the new first limiting amino acid (e.g., isoleucine, arginine, or tryptophan). For a United States based example, the result is less oilseeds and more gains, which typically result in increased inclusions in corn or corn...

Overview Corn is the most common feed ingredient used in poultry nutrition. Maize contributes with up to 65% of the metabolizable energy and 20% of crude protein in poultry diets (Gehring et al., 2013; Dei, 2017). Its average nutritional value is well-known, but it is accepted that the variability in its composition and energy value is a very common issue with great impact on poultry performance and health (Cowieson, 2005; Gehring et al., 2013; Latham et al., 2016;...

INTRODUCTION Globally, corn becomes a major ingredient for animal feed either as whole grain or by-product from corn milling industries. There is several corn co-products derived from wet or dry corn milling industries (Tangendjaja & Wina, 2007) and at least 2 co-products commercially available in Indonesia for poultry feed, namely corn gluten meal (CGM) and dried distillers grains and soluble (DDGS). CGM is a co-product obtained during wet milling process to produce maize...

Introduction An essential component of the overall health and well-being of the broiler chicken is ensuring that mineral nutrition, in all its facets, is adequate. As growth rates increase and production systems intensify, mineral nutrition will become more critical. Most minerals in the bird occur in the skeleton, so skeletal integrity is perhaps the critical issue. However, minerals play a role in all aspects of metabolism, both as cofactors of enzymes and controlling free...
