Makouei sheep is one of the famous breeds in Iran which is reared in Azerbaijan province for their meat, milk and wool. Fifty clinically healthy Makouei ewes were selected to study the variations in energy-related blood metabolites during peri-partum period. Blood was collected from Jugular vein from each sheep on day 7 before the expected lambing time, day of parturition and also day 7 postpar...

The objective of this experiment was to determine if providing ewes in the final trimester pregnancy with choice from diverse diet components would reduce markers oxidative and metabolic stress improve lamb birth weights relative offered only one forage species, repetitively. Fifty-four, twin bearing Coopworth [initial live weight (LW) = 69.82 ± 1.16 kg] were blocked by onto iso-energetic diets...

Abstract The management of sheep reproduction requires the induction and synchronization estrus cycle ovulation for ewe out-of-season and/or synchronized lambing. These managements are based on insertion an intravaginal device controlled internal drug release (CIDR or sponge) then administration a hormonal injection, such as PMSG, eCG, hCG, GnRH. This study aimed to compare impact CIDR sponges,...

Three experiments were conducted to determine: (1) the direction of uterine contractions in Days 32 and 52 postpartum ewes (Experiment 1); (2) the effect of PGF(2alpha) on direction of uterine contractions (Experiment 2); and (3) the effect of PGF(2alpha) on fertility rates in Day 32 postpartum ewes (Experiment 3). In Experiment 1, non-lambing (>90 days postpartum) and lambing ewes (day of lamb...

Ewes bearing more than 1 fetus are more susceptible to pregnancy toxemia than those with a single fetus. Crossbreeding programs in Israel increased the occurrences of ewes bearing more than 2 fetuses; therefore, the aim was to assess the exacerbation in the metabolic status of ewes pregnant with several fetuses. Fifty ewes, genetically developed to achieve multiple-fetus pregnancies, were monit...
