INTRODUCTION Cereal grains such as wheat, sorghum, barley, and corn are commonly used in poultry diets as major sources of energy. Knowledge of the ME content of cereal grains is critical for their efficient and sustainable use and precise poultry feed formulation. Despite several limitations (Mateos et al., 2019; Wu et al., 2020), the AME is the globally accepted system for describing the available energy for poultry (Hill and Anderson, 1958; Sibbald, 1982). The simplicity,...

INTRODUCTION Aiming at reducing production costs and the impacts of animal production waste on the environment, research has focused on improving the efficiency of feed utilization.One strategy to reduce the excretion of pollutant compounds is to increase the nutritional availability of feeds by the dietary supplementation of exogenous enzymes (Nahm, 2002). Phytase, for instance, allows reducing inorganic phosphorus supplementation and increasing phytic acid utilization by the...

1. Introduction Often a seemingly straightforward aspect of nutrition reveals itself to be, upon closer inspection, not so simple after all. An illustration of such a conundrum is the nutrition of the newly hatched broiler chick. Conceptualizing the different challenges faced by the hatchling and solving them should be remarkably simple, but the difficulty lies in the complexity in the development of the gastrointestinal tract (GIT), digestive physiology, immune system, and...

1. Introduction Available energy in feed or feed ingredients for poultry can be measured by different systems, with the apparent metabolizable energy (AME) [1], despite its limitations [2,3], being the commonly accepted and extensively used system. Three methods, namely, direct, substitution (or difference), and regression, have been used to determine the AME of ingredients for poultry. In each method, the excreta can be collected by total collection, which is the...

INTRODUCTION Although rearing the meat poultry in cage systems has recently attracted a lot of attention, however, some of the meat poultry stocks particularly broiler chicken still grow up on the floor of the poultry houses with a substrate known as litter material as poultry bedding. The recent trend in poultry industry has increased the demand for litter materials. Litter serves a number of important functions, such as absorbing moisture of excreta, reducing contact between...

Though paper evaporative cooling pads have been used by poultry producers for decades, plastic pads are a relative new phenomenon. As with any new product, there are a lot of questions. By far the most common question is whether plastic pads can produce the same level of air cooling as traditional paper pads. In short, the answer is yes. But just...

Something to consider. If we preheated and ventilated a house long enough prior to chick arrival, the need for a litter treatment would be drastically reduced, if not possibly eliminated. Litter treatments are used primarily because the cost of preheating and ventilating a house long enough prior to chick arrival to remove excess moisture...

In 2021 mycotoxins semiannual survey, Life Rainbow Biotech randomly collected 230 feed samples of raw materials and feed mills in farms and analyzed. The samples were tested for Aflatoxins (B1, B2, G1, and G2), Zearalenone, Fumonisins (B1, B2, and B3) and Deoxynivalenol (DON) by the ELISA Mycotoxin analysis kit. Results: 230 feed samples collected, and 78% were contaminated with deoxynivalenol and 86% contaminated with Aflatoxins (table 1). The maximum concentrations of...

Windrowing has become a very popular method of managing litter between flocks. In order to get the most benefit out of windrowing, the litter needs to be relatively damp. How damp? Ideally, the litter moisture content would be between 25 and 35%. At this level of litter moisture, when you grab a handful of litter and squeeze it, it would...

The level of ammonia young chicks will be exposed to during the first week of their lives is determined to a large extent by what was done to the litter between the flocks. Towards the end of a flock, the birds are adding thousands of gallons of water to a house each day. During cold weather, reduced ventilation...

Though broilers often appear to be evenly distributed throughout a house, more times than not our eyes are deceiving us. Figures 1 and 2 are of the tunnel fan and tunnel inlet ends of a 50' X 600' broiler house with 20-day-old birds. At first glance bird density appears fairly uniform but when examined closely, it becomes apparent that there are more birds near the tunnel doors (far right of Figure 2) than in any other area of the house. The question are, of course, is this...
