Effect of Recombinant Luteinizing Hormon (rLH) on Some Fertility Parameters in Awassi Ewes Synchronized with PGF2α in the Breeding Season

Abstract

The aim of this study is to investigate the effects of three different doses of recombinant Luteinizing hormone (rLH), applied 48 hours after the second prostaglandin F2α (PGF2α) injection apart 9 days in oestrus synchronization on reproductive performance of Awassi ewes. Eighty purebred Awassi ewes given birth to at least one lamb were used. All ewes were treated with PGF2α consisting of two IM doses of a PGF2α analogue (1.25 ml, 0.093 mg–D-Cloprostenol of per dose, Dalmazin®, Vetas,Turkey) administered 9 days apart. Animals were the randomly allocated to four equal groups and 48 h later a single intramuscular (IM) dose of rLH (Group1 0.5 IU; Group 2, 7.5 IU; Group 3, 10 IU) control group was injected with 1 ml normal saline solution. The oestrus was controlled at 48 hours later. Artificial insemination was performed with fresh diluted semen collected from fertile Awassi rams after observing oestrus behaviors. The pregnancies were determined with transrectal ultrasonography at 40th day after artificial insemination. There were no statistically significant differences (P>0.05) between the treatment groups and the control group for estrus response (Group 1, 90.0 %; Group 2, 85.0 %; Group 3, 80.0 %; Control group, 90.0 %). Pregnancy rates were 50.0 %, 47.06%, 50.0 % and 50.0 % in groups 1, 2, 3 and the control group, respectively. Lambing rates in treatment groups (89, 100-%) were similar to control group (100 %). Lambing rates in Groups 1, 2, 3 and control group were 89.90 %, 100 %, 100 %, and 100 % respectively. Single birth rates and twinning rates in three different rLH groups were similar to control group. There were no statistically significant differences on the lambing rates, single and twinning rate among the treatment groups and control group. These results indicated that the three different doses of rLH after oestrus synchronization with PGF2α did not affect the fertility parameters in Awassi ewes.
