  About 184 Zel ewes, 3-5 years of age and a body weight of between 40 and 45 kg were used in the trial. Ewes were randomly allocated to 4 treatments groups based on BW and age (46 ewes/group). All of the ewes were fed in two nutritional groups including low (2 mcal kg-1) and high (2.3 mcal kg-1) metabolizeble energy diet. Ewes received experimental diet until 28th day of experiment. The estrous cycles of ewes were synchronized using SIDR and 2 levels of PMSG (300 and 500 IU). Treatments include: 1-High energy and 300 IU PMSG (H300), 2-High energy and 500 IU PMSG (H500), 3-Low energy and 300 IU PMSG (L300) and 4-Low energy and 500 IU PMSG (L300). Jugular blood samples were collected from ewes using vacutainers at 10 h in first day of experiment, CIDR insert day, CIDR removal day before mating and 120 h after mating. Bloods samples centrifuged at 3000x g for 15 min then serum immediately separated and kept frozen at -20°C until analysis for insulin, FSH and progesterone. Repeated measurements used for data analysis. The result showed that there were no any significant difference between two groups weight before start the experiment (p>0.05). During the experiment high level of energy increased the body weight than low level group (p<0.05). Energy had no significant effect on blood FSH and progesterone concentration (p>0.05) but high level of energy decreased the insulin concentration significantly (p<0.05). In this study PMSG had no any significant effect on blood metabolites such as FSH, Insulin and progesterone.

  One hundred eighty four Zel ewes, 3-5 years of age were used to evaluate the effects of strategic supplementary feeding prior to mating and doses of PMSG to ewe synchronization on reproductive performance of Zel ewes mated to Zel or Shal rams. The ewes fed diets containing two levels of metabolizable energy, 2.0 or 2.3 Mcal kg-1 with 115 g kg-1 DM crud protein for 21 days prior to mating period. After 7 days of experiment, the ewes were synchronised with intra vaginal CIDR devices containing 1.9 g progesterone for 14 days. Ewes received 300 or 500 IU of PMSG injection at CIDR removal time and later mated with Zel or Shal ram. All important reproductive parameters such as ewe fertility, prolificacy, lambing rate, lamb mortality and twining measured. The results showed that Shal rams increased ewe fertility (p<0.05) but not affected by PMSG administration and flushing. Ewes bred to Shal rams had higher fertility compared to ewes bred to Zel rams. Prolificacy was not affected by PMSG administration but it was significantly affected by diet and ram (p<0.05). High dietary energy resulted in a higher prolificacy. Lambing rate changed with energy level and ram breed (p<0.05) and high level of energy increased lambing rate by 26%. Administration of 500 IU PMSG resulted in higher lamb mortality in compared to 300IU (p<0.05). High level of PMSG and flushing diet increased twining rate (p<0.05) but ram had no any effect on twining rate.

  An experiment was conducted by eight lactating Holstein cows with an average milk production of 32.75 kg day-1 and body weight of 643.6 kg to evaluate the effects of propylene glycol (PG) on productive performance, blood metabolites and nutrients digestibilities. In this experiment a balanced change-over design with four treatments and four periods with 21 days were employed. Treatments included: (1) Control (without PG), (2) 250 g PG/cow/day, (3) 500 g PG/cow/day and (4) 750 g PG/cow/day. Daily milk yield recorded and milk samples were taken during seven and two last days of each period. The results show that dry matter intake, milk yield, fat corrected milk yield, milk compositions were not affected (p>0.05) by different levels of PG. Supplementing diets with 500 and 750 g PG/cow/day, significantly increased plasma glucose (p<0.05) but other blood metabolites such as blood urea nitrogen, triglyceride and cholesterol were not affected (p>0.05) by PG. Apparent digestibility of dry matter and organic matte was not affected (p>0.05) by PG administration. In conclusion, plasma glucose was increased by using 500 and 750 g PG/cow/day (as powder) in the first and mid lactation stage, but the levels of 250 g PG/cow/day did not have any significant effect on dry matter intake, milk yield, milk compositions and other blood metabolites.
