| Abstract | ||||
| This study estimated quantity of water, feed consumption and body weight of buffaloes and cows under different climatic regions in Egypt, Data used in this study were collected from six governorates, each two governorates represented different climatic region in Egypt. The study began in January (2010) to December (2015). Monthly visits to each governorate were occurred. The investigation was carried out via three climatic regions [Lower Egypt (LE), Middle Egypt (ME) and Upper Egypt (UE)]. In each governorate, total of 5 villages and 3 farms in each village were represented as a small, medium and large scale farm per village. The measures were taken from 12 animals, perform (6 buffaloes and 6 cows) in two ages groups (G1, 9-12 months of age and G2, 12 -18 months of age). Each farm was visited only one time. Essentially, the animal's respiration rate (RR, r/min), water intake (WI, L/day), feed intake (FI /Kg) and body weight (BW/ Kg) were measured. Data of environmental conditions collected were air temperature (AT, °C) and relative humidity (RH, %) to calculate temperature humidity index (THI). A prediction equation was developed based on of THI values WI, L/day, FI/Kg and BW/Kg the main obtained results were: The highest values of THI were detected in Lower Egypt (LE). , while The lowest THI values were in Upper Egypt (UE), The best values of respiration rate (RR, r/min) for the two species of animals (buffaloes & cows) were in Upper Egypt (UE), The relationship between RR r/min and water intake (WI, L/day) was linear for the two species of animals under the three climatic regions , Values of WI, L/day and concentrates feed intake (FI, con /Kg) by cows were more than those of buffaloes for the two ages groups and the significances was clear in G2, under the three climatic regions., The values of roughage intake (FI, R /Kg) were nearly the same for the two species. Animal consumption of water was higher in Lower Egypt (LE) and the lower consumption recorded was in Upper Egypt (UE). Water intake (WI, L/day), continued to increase linearly with increasing THI by the two species (buffaloes &cows), while feed intake (FI/Kg) decreased. Body weight (BW/Kg) of cows were higher than buffaloes in the three climatic regions. By using the predictive equations in the different climatic conditions, one can be enable to detect good earlier estimate of the productivity of the animals. Estimation of THI index in any climatic regions is a helpful tool to predict consumption of water by the two species (buffaloes &cows). Results indicated in accurate the higher prediction ability of amount of water intake for the two species based on the changes occurred in THI. In conclusion the best climatic conditions for the two species is between 71- 74 THI in the three climate regions. The higher consumption from water was in Lower Egypt and the lower consumption was in Upper Egypt. It is very important with climatic changes, using the prediction equation which enable maintaining water and productivity of animal without greater drop of production. This study concluded that it is still possible to maintain or increase meat production from buffaloes and cows under different climatic regions, particularly in Upper Egypt (UE), with available suitable shades above animals, and shading watering to protect from solar radiation direction. | ||||
