Abstract

The effect of FLUSHING by the use of a supplementary feeding and OESTRADIOL BENZOAT on REPRODUCTIVE EFFICIENCY of Zel ewes was compared. 200 ewes of 4-5 years old were randomly allocated into four groups in lowland pasture of Golestan province. Four treatments were applied to these four groups of ewes as follows: Group one (control), group two using nutritional FLUSHING, group three using nutritional FLUSHING plus one injection of 0.5 ml OESTRADIOL BENZOAT hormone, group four using one injection of 0.5 ml OESTRADIOL BENZOAT hormone. Each ewe in groups two and three was given 300 grams of a mixed concentrate ration, containing barley grain 60, wheat bran 10, beet pulp 30 percentages for 28 days prior to tupping. For each group of ewes two teaser rams were used to detect heat. The results showed that ewes were received OESTRADIOL BENZOAT with or without nutritional FLUSHING, had signs of estrous after 24 hours of injection. Ninety- two percentages of ewes in group two showed signs of estrous after 14 days of FLUSHING. The amounts of non-return rates of ewes were 74, 98, 96, and 86; and lambing percentages of ewes were 84, 120, 128, and 102; and twinning percentages of ewes were 11, 22, 32 and 16 respectively for four groups of ewes. In conclusion, the use of nutritional FLUSHING plus injection of OESTRADIOL BENZOAT for inducing estrous synchronization and increasing REPRODUCTIVE EFFICIENCY can be suggested for ZEL BREED of sheep.
