The Effects of Non-Genetic Factors on Dairy Cattle Performance in East Africa Estimation of the Seasonal and Parity Differences

Abstract

The weather and climatic regimes in the tropical one are such that seasonal grouping can be done by dividing the calendar year into either the dry and the rainy months or the hot, warm and the cool months of the year. In the Sub-tropical zones of India, Pakistan, Brazil, Egypt, Middle East and Australia, seasonal classification is to some degree similar to what is used for the temperate zone.
