Poultry nutrition - Other additives
Alternative feed additives have promising importance in broiler production due to the ban on the use of certain antibiotics. The most used antibiotic alternatives in broiler production are phytogenics, organic acids, prebiotics, probiotics, enzymes, and their derivatives. Antibiotic alternatives have been reported to increase feed intake, stimulate digestion, improve feed efficiency, increase growth performance, and reduce the incidence of diseases by modulating the intestinal microbiota and immune system, inhibiting pathogens, and improving intestinal integrity. Simply, the gut microbiota is the target to raise the health benefits and growth-promoting effects of feed additives on broilers. Therefore, naturally available feed additives are promising antibiotic alternatives for broilers.

Hi, I have around 200 lohmann brown laying hens (average 3kgs) but I got this problem. I used to give them feed in abundance, I mean, as much as they want to eat, but I was told I should feed them with 110g per hen. So I calculate it and it would be like 22 kilograms per day, but they eat all the feed really quickly and remains hungry… any suggestion? Is the ration ok, or I should feed them till they are satisfied? Thanks ...

During the past cycle we experienced the following: mucoid enteritis; disfunctional ceacum; contents of ceacum is watery and filled with bubbles in the feed passage; undigested feed particles in the small intestine; wet droppings due to liquid ceacal content.There were no abnormal mortallitys.The growth performance were very poor and the feed conversion were also very poor. This scenario started at a age of 25 days till slaughter on 34 days. My personal feeling...

1. INTRODUCTION Hot environmental conditions are a problem for poultry producers in many areas of the world, particularly in the humid and hot tropics and sub-tropics. Some studies investigated the influence of thermal environment and dietary nutrient level on the productive traits of broiler chickens (Gu et al., 2008; Attia et al., 2011). The nutrient requirements of poultry are altered as the environmental temperature...

Introduction For several decades, the use of sub-therapeutic levels of antibiotics in animal feeds has been a common practice in many countries in order to improve growth performance and prevent from the adverse effects of pathogenic and non-pathogenic enteric microorganisms. However, there are increasing concerns for the public health about the consequences from the use of antibiotics in livestock [1]. The risk of...

Corn is the main ingredient used in poultry feeds, representing more than 60% of the diet. Through fertilization of corn crops, changes in grain nutrient composition may be expected. A trial was conducted to evaluate the effect of several fertilization strategies on the nutrient content of corn. A 2x2x2 factorial arrangement was performed considering, 2 corn genotypes (Yellow dent or Flint corns) x 2 levels of Nitrogen (N) fertilizer (0 kg/ha or 50 kg/ha at...

Introduction It has been observed that there are lots of controversies in poultry nutrition regarding the use of feed ingredients from Animal sources. Many poultry experts are against to use animal sources such as Meat cum bone meal and Animal fat in poultry feed. But nowadays, due to use of highly modern Rendering technologies, the By-products of Abattoirs such as MBM and Animal Fat produced...

Guar meal (GM) is mostly used as a protein source in poultry diets. However it contains a broad range of galactomannan gum and some other anti-nutritional factors which decrease its metabolisable energy (ME) value. It is also showed that technique to measure metabolisable energy influences validity of results. In this regard, Sibbald (1987) showed that in comparison with the total collection method, the use of markers to determine ME...

Nutrient Requirements A nutritionist’s goal is to match nutrient supply to the nutrient requirements of the flock. Therefore, feed allocation decisions for broiler breeders are driven by nutrient requirements. Ideally, feed would be allocated according to the needs of every bird. In reality, flock managers must still make feed allocation decisions according to the average bird. ...

Betaine (tri-methyl glycine) is a methyl donor which supplies the methyl groups for methionine production. It therefore may be able to support higher levels of growth in diets based on vegetable protein sources, which tend to be deficient in glycine and serine. There is evidence that betaine can improve nutrient digestibility by supporting intestinal function and growth (Eklund et al., 2005) Betaine is an osmoprotectant and commonly used to overcome...

Reducing stress in poultry remains a topic of concern with producers and scientists alike. Poultry production efficiency is adversely affected by high ambient temperatures and humidity. As the birds' body temperatures rise, feed consumption, growth rate, feed efficiency, survivability, egg shell and chick quality decline. The problem is particularly severe as the ambient temperature rises since heat loss associated with non-evaporative cooling (heat lost through...
