THE EFFECT OF SALINE WATER INTAKE AND FEEDING SALT TOLERANT PLANTS ON THERMOREGULATION AND PRODUCTIVE EFFICIENCY OF BARKI SHEEP IN SOUTH SINAI
Khaled Aly Ahmed El Shemy;
Abstract
This study was performed in order to investigate the impact of salinity in drinking water and feeding diets containing salinity tolerant plants on production and reproduction efficiency and the amount of thermoregulation of Barki sheep under semi-arid condition in Egypt.
This research was carried at South Sinai Research Station situated in Ras Sudr (latitude: 2926236
N; longitude: 3227648 E; elevation: 66 m), South Sinai Governorate, belonging to the Desert Research Center (DRC), Ministry of Agriculture and Land Reclamation, Egypt. Chemical analysis was executed in the Animal Production Lab of South Sinai Research Station. Whereas, determination of wool parameters and histological features and hormonal assays were conducted in the Central Lab of DRC.
Twenty nine adult ewes of 2-3 years old from Barki sheep breed were randomly assigned into four different feeding groups (7, 7, 8 and 7 animals for group 6, 2, 3 and 4, respectively), according to both type of drinking water (i.e. tap water or saline water) and feed (i.e. berseem hay or salt-tolerant plants like Alfalfa) as the following: The first group (G6): was fed on berseem (Trifoliumalexandrinum) and drank tap water (274 ppm) and served as the control. The second group (G2): was fed on berseem hay (Trifoliumalexandrinum) and drank saline water (6000
ppm).The third group (G3): was fed on salt-tolerant plants (alfalfa) and drank tap water.The fourth group (G4): was fed on salt-tolerant plants and drank saline water. All experimental groups were offered concentrate feed mixture (3/4 kg /head/day) to cover their different physiological requirements of energy.
All experimental animals were kept in semi-open pens under the same managerial and hygienic conditions and diagnosed as clinically free from internal and external parasites. Once lambing took place, the born lambs were identified by ear tag and left with their dams till weaning at 3
months of age
