IntroductionThe impressive genetic improvement of poultry growth rate has led to a modern bird with a very low feed conversion rate (FCR), high average daily gain (ADG) and low mortality. Unfortunately, this fast growth rate is often directly linked with digestive problems, such as bacterial enteritis (BE) or dysbacteriosis and even necrotic enteritis (NE). These intestinal health problems have si ...

IntroductionModern broiler chickens are most certainly a most visible manifestation of genetic advancements. At hatch, a Cobb500 broiler weighs 42 grams. This newborn chick grows 31 % (55 g/bird) in just twenty-four hours. By day 35 of age, this chicken reaches a body weightof 2,521 grams, representing 5,902 % relative to hatching mass (Cobb-Vantres 500, 2022). Genetic selection, food, health, and ...

Getting chicks on to feed and water as quickly as possible after arrival on a farm has long been recognized as the key to maximizing overall performance. If provided the ideal environmental conditions and plenty of feed and water, chick weights should increase by roughly 50% during the first 48 hours compared to only 2% over the last 48 hours of the flock! Quite simply, the less time it takes chic ...

I IntroductionAs the single greatest nutrient input into the production of eggs and meat, water quality and quantity deserve careful attention to assure optimal flock performance. Twenty-five years of assisting the poultry industry worldwide with identifying and correcting drinking water challenges provides the foundation of experience and expertise which will be shared in this paper.Birds are fai ...
