Amino acids in poultry nutrition
Adequate provision of dietary amino acids is required to maintain normal immunocompetence and protection of the host from some diseases in all species (Beski et al. 2015). Therefore, the development of immune function in poultry will be promoted if they receive sufficient amino acids in their diets. The essential amino acids for poultry are arginine, glycine, histidine, leucine, isoleucine, lysine, methionine, cystine, phenylalanine, threonine, tryptophan, and valine. Out of these, the ones critical in practical diets are arginine, lysine, methionine, cystine and tryptophan.

Ewa Sujka, from Liptosa company, had us a short interview where she spoke about their best seller product, MethPlus. She talked about the product being tested on laying hens and without a negative impact on laying performance and egg quality. In fact she said the product reduced the cost of the diet and makes you save money. She also spoke about the improvement the product gives to egg quality....

Introduction Chronic heat stress (HS) is a great concern in all types of poultry especially broiler chickens. Reductions of feed intake (Teeter ., 1985) and lower growth rate as well as reduction in feed efficiency (Geraert ., 1996) have been reported in poultry under HS condition (Ramnath., 2008). Birds attempt to compensate for their reduced ability to dissipate heat during heat distress by increasing their physiological processes (such as, elevated body temperature, panting...

Introduction Quail farming is very important for providing jobs and producing high quality protein at a low cost. Nutrition during the growing phase of the birds can influence their performance during the production phase. Most research has focused on the nutritional requirements of quails during the laying phase and there is little information about requirements during the growing phase. Quails are characterized by early sexual maturity (40 days), demanding feeding programs...

INTRODUCTION One of the most important roles of animal production is to provide high quality protein for human consumption and, to achieve this proposal, animals should be fed correct proportions of high quality protein in the diets. Amino acids are key factors in animal nutrition since protocols used to evaluate protein quality are related to amino acid supply. Poultry feed formulation was until recently based on the concept of crude protein, which frequently resulted in...

INTRODUCTION There is increasing evidence that cereal grains used for poultry feed are commonly contaminated with mycotoxins. Mycotoxins are toxic compounds produced by fungi, when present in the feed depress nutrient quality of the feed and hence the health and performance of poultry. The tropical and subtropical climate with hot and humid condition prevailing in India coupled with poor harvesting of crops, inadequate drying and storage facilities, and insect infestation...

INTRODUCTION Aflatoxin is the common name for a group of chemically related compounds (Moss, 1996) produced by certain strains of Aspergillus flavus and A. parasiticus in the feedstuffs as poisonous secondary metabolites. Aflatoxins are stable once formed in grain and are not degraded during normal milling and storage process (Brown, 1996) and have been demonstrated to be carcinogenic, mutagenic and teratogenic (Cole and Cox, 1981). It impairs humoral and cellular immune...

Key information Compared to growing poultry, exact determination of the relative bioavailability of methionine hydroxy analogue compared to MetAMINO ® is constrained by physiological mechanisms in laying hens which often result in overestimation of the relative bioavailability. The relative bioavailability of 65 % for methionine hydroxy analogue is applicable in layers and bears no risk in terms of performance depression, as confirmed by three recent feeding...

Introduction Broilers diets are usually based on corn and soybean meal; in most cases, animal by-products are also used as raw material. Considering that the main source of crude protein in broiler diets is soybean meal, the first limiting amino acid for broilers is methionine, which has to be supplemented in the feed from industrial sources available on the market (Lemme et al., 2002). The most common sources of methionine in the supplements available to the poultry...

Introduction The inclusion of exogenous enzymes in broiler diets has been increasingly intensified with the objective of maximizing nutrient utilization and reducing feed costs, thus improving dietary, nutritional and energy levels (Adeola & Cowieson, 2011). Exogenous enzymes improve the nutritional value of feed ingredients due to the degradation of specific bonds not efficiently hydrolyzed by the endogenous digestive enzymes of birds and to the degradation of...
