Aflatoxins (AF) are a major concern in poultry production and public health because of serious economic losses and health problems. AF contamination causes reduced feed quality and reduced animal efficiency either through poor conversion of nutrients or problems such as reproductive abnormalities. Aflatoxicosis in poultry also causes listlessness, anorexia with lowered growth rate, poor feed ut...

Cereals are grasses that produce edible starchy grains, many of which can be used in poultry diets as an energy source. Although the starch in corn is highly digestible, most of the other grains contain antinutritional factors that interfere with digestion and/or the absorption of nutrients. These antinutritional factors include the nonstarch polysaccharides, often referred to as NSPs. NSPs can...

There is a general agreement between researchers that particle size of poultry feed should be between the size ranges of 600-900 µm. This study investigated the particle size of poultry feed produced in the Dormaa Municipality of Ghana. A survey was conducted on various feed mills which were made up of nine on-farm mills and five community-based commercial mills. Feed samples were collected fro...

Mycological and mycotoxicological analysis of many feedingstuffs and complete mashes for different animal species and categories have showen that the feed safety problem has been present for years. It is approved that mouldy feed can contain various mycotoxins, but among them in our conditions the most investigated are aflatoxins, ochratoxins, zearalenone and some trichotecenes. Based on labora...

The major goals of the poultry industry are to increase the carcass yield and to reduce carcass fatness, mainly the abdominal fat pad. The increase in poultry meat consumption has guided the selection process toward fast-growing broilers with a reduced feed conversion ratio. Intensive selection has led to great improvements in economic traits such as body weight gain, feed efficiency, and breas...

The study was conducted to determine the absorption of essential and non-essential trace minerals from poultry feed products. Poultry feed, liver, muscles, egg samples were collected six farms in Rawalpindi Islamabad. Mercury, Lead, Cadmium, Chromium, Iron analyzed using Inductively Coupled Plasma Optical Emission Spectrophotometer. Iron, Chromium exceeded permissible limits set by World Health...

The nutritional value or quality of dietary proteins used for poultry feed formulation varies: amino acid availability is an important measure of protein quality. Determination of ileal digestibility values has become the preferred method for estimating amino acid availability. This review discusses the different approaches to the expression of digestibility results, including correction for en...

As grain prices have increased dramatically in the past year, understanding the fundamental genetic, cellular, and biochemical mechanisms responsible for feed efficiency (FE; g of gain/g of feed) or residual feed intake (RFI; an alternative feed efficiency trait that quantifies interanimal variation in DMI that is unexplained by differences in BW and growth rate) in livestock and poultry is ext...
