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. ...

Breeding is defined as the crossing of the male and the female parents to get the off spring for the characters desired. The main breeding methods are:1) In Breeding2) Out BreedingThey are further classified as given in the chart below:(1) INBREEDINGInbreeding is the mating of closely related individuals, whose relationship is more than the average relationship of the population. The example ...

A breed is a group of related animals with similar characters like general appearance, size, features and configuration etc. Often, breeds resemble each other with slight morphological differences, but because of constant inbreeding in one locality, independent breeds have evolved. In general, the cattle from drier regions are well built and those from heavy rainfall areas, coastal and hilly regio ...

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 ...
