INTRODUCTION:Dl-Methionine is the critical amino-acid for poultry. Supplementation of DL-methionine in poultry ration is well established to improve growth and performance in broilers. (Swick et.al, 1990). Methionine must be supplemented in the diet of chi9cken as the poultry birds are unable to synthesize it in the amounts necessary to sustain life and growth. Methionine is required at higher lev ...

Diseases are produced by micro-organisms which are universal and single organisms reproduce and multiply number of times. Disease incidences are higher in old and densely populated poultry farms.Bio-security is of immense help to reduce disease hazards and improve health and productivity of birds. Optimum and profitable poultry production can be achieved by reducing disease risk to minimum extent. ...

The environment can be defined as the combination of external conditions which have an impact on animals and humans. Perhaps the most important physiological response of poultry to the environment is the constant maintenance of a homoeothermic state during exposure to extreme ambient temperatures. Environmental stress causes adverse effects on performance of poultry.There are different types of st ...

Intestinal diseases are an important concern for modern poultry industry because of low productivity, increased mortality, reduced welfare and the associated contamination of poultry products with pathogenic bacteria and their toxins.Several pathogens (Viruses, bacteria and parasites) are incriminated as possible causes of enteric disorders either alone (mono-casual), in synergy with different oth ...

IntroductionDisease prevention through vaccination is one of the aspects of bio-security. Disease causing organisms can be classified as smallest to largest - viruses, mycoplasma, bacteria, fungi, protozoa and parasites. All these organisms are susceptible to chemotherapy, except viruses. Bacterial infections are controlled through antibiotics but not much medication is available to fight viral in ...
