|
|
Abstract: The data used in this study were collected from two cities (Al-Saf and Atfieh cities), Giza Governorate. The data collected during one year from 928 records (445 records for buffaloes and 483 records for Friesian).
The main objective of this study was to establish an animal discomfort index for buffalo and Friesian based on changes in their physiological responses with climatic changes under natural conditions which could be used as an indicator best region to raise buffalo and Friesian under Egyptian conditions. i Results indicated that, beginning the decline of production and physiological reaction under moderate heat stress (78.02 %). The true decrease in production with higher of values of RR and RT under dangerous (90.85 %). The cover of animals it controlled to adapt for around environmental condition. The outcome of the physiological reactions and behavioral performances is reflecting on production. This gave indicator to the buffaloes with climatic change more efficiency than Friesian agreement categories of THI under environmental Egyptian condition.
Key words: Temperature humidity index, physiological reaction, buffalo, Friesian, Egyptian condition.
