Abstract Sheep are considered short-day breeders. Exposure of rams to anestrus ewes results in an increase in LH secretion. The aims of this study was to determine whether the presence and exposure of rams can effect on reproductive performance such as: pregnancy rate, litter size, sex of lamb, fecundity rate and prolificacy rate of fat tail Iranian Shaal breed ewes in non-breeding season using progesterone (p4) analogue with or without equine chorionic gonadotropin (eCG). Totally, 100 ewes out of 138 non-cyclic ewes with <0.5ng/ml P4 were selected for this study. They were aged 2 to >7 years old. They were stratified to two groups (control and treatment). The ewes in treatment and control groups received 13 days a sponge containing 60 mg medroxyprogesterone acetate (MPA). The treatment group consists of 3 subgroups and each group contains 25 ewes equally. They were included: 1- P4, eCG and Ram exposure. 2- P4 and ram exposure. 3- P4 and eCG. Ewes in control group received only P4. The ewes were located in isolated corrals for 40 days. The ram to ewe ratio was 1 to 5. Twenty healthy rams were housed in an isolated pen from ewes with distance 1500 m during 40 days. Rams exposed three days before sponge withdraw (day 10). They were separated by considerable distance (2 meters) using fence. The related groups received 500 IU eCG on the day of sponge removal (day 13). The rams were released into the ewe flock after removing the sponge in treatment and control groups. Pregnancy diagnosis performed using transabdominal ultrasonography. The obtained data analyzed using SPSS version 16. The conception rate in treatment and control groups were differed significantly (P<0.01). The conception rate in P4+ram exposure+ eCG, P4+ramexposure and P4+ eCG were 96%(no.24), 80%(no.20) and 88%(no.22), respectively. However, the conception rate in control group was 60% (no. 15). The fecundity rates were 136%, 100% and 124% in treatment subgroups, however, it was 84% in control group, respectively. There were no significant differences among genus and weight of lambs in treatments subgroups and control group (P>0.05). It is concluded that ram exposure can increase significantly reproductive performance in non-breeding season fat tailed ewes Shaal breed.

This study investigated the efficacy of intrauterine infusion of a chitosan solution (CHT) on uterine recovery in early postpartum dairy cows with or without endometritis, and their subsequent reproductive performance. In Experiment 1, cows with endometritis at 3 weeks postpartum were administered CHT (n = 5) and prostaglandin F2α (PGF2α) (n = 4). Untreated cows (n = 7) served as the control group. In Experiment 2, 18 cows with a normally recovered uterus at the fresh cow check (mean, 35 days postpartum) were assigned to the CHT (n = 10) and control (n = 8) groups, and intrauterine infusion was conducted in the CHT group. Overall, in Experiment 1, the percentage of polymorphonuclear leukocytes significantly declined in the CHT group (32.3 ± 10.2 to 5.5 ± 2.4, p < 0.05) from week 3 to week 5, but no decline occurred in the PGF2α and control groups. In Experiment 2, the CHT and control groups showed no significant differences in reproductive parameters, suggesting the absence of adverse effects of CHT on fertility. These results suggest that intrauterine infusion of CHT in the early postpartum period effectively accelerates uterine recovery from endometritis and might be a suitable replacement for PGF2α administration.

 The objective of this study was to carry out an on-farm experiment in sheep owner farms in Kanaan district for the period from 7th Feb. 2015 to 27th Mar. 2015 and to identify the unconventional methods in controlling the reproduction in sheep and increase their productivity using 45 local Awassi ewes, randomly selected from three sheep owners (15 ewes / owner). Treatment group (10 ewes/ owner) were treated with a vaginal sponges containing 20 mg fluorogestone acetate (FGA) inserted for 10 days, followed by I.M. injection of 500 IU equine chorionic gonadotropin (eCG), while 5 ewes / owner were regarded as control group without any treatment. Estrus was observed for all ewes for 5 days post withdrawal of sponges. Ewes that showed estrus were mated by rams in their flocks, thereafter, pregnancy detection was conducted at days 35-37 post- mating using transabdominal ultrasonography. A questionnaire involved 20 sheep owners and a demonstrative field day was conducted for owners contributed in the experiment, and others from the region of study to explain the importance and results of the experiment. The results showed the appearance of estrus in all ewes 100% within three days after the withdrawal of sponges. Pregnancy rate of  85.71% at days 35-37 of mating. The questionnaire showed there is an urgent need of knowledge for owners to find out the importance of controlling the reproductive cycle in sheep using vaginal sponges. Also, there were a correlation between the need of knowledge for sheep owners with (educational level for most of them, herd sizes, income from breeding, training courses and other activities in the fields of breeding and reproduction of sheep). In conclusion, the technology of estrus synchronization has an important role to improve reproductive performance of sheep and pregnancy could be detected through transabdominal ultrasonography at 35-37 days with high accuracy as well as there is great desire for the most owner to conduct estrus synchronization technique and to take care their birth of herds simultaneously.

The study was undertaken to find out the estrus induction and conception rate in 18 postpartum anestrus Surti buffaloes divided equally into three groups and treated with Ovsynch protocol alone and in combination with PRID, keeping one group as control. The use of Ovsynch alone and Ovsynch + PRID protocols with fixed-time artificial insemination resulted in 100% estrus induction with 66.66% and 50.00% conception rate at induced estrus, respectively, and the overall conception rate was 83.33% in both the groups. In untreated anestrus control (n=6), only four (66.66%) buffaloes exhibited spontaneous estrus within 120 days of follow-up and conceived giving the first service and overall conception rate as 75.00% and 66.66%, respectively. The mean number of services per conception did not differ significantly among the treatment and control groups. The service periods of buffaloes under both the treatment groups were significantly (p less than 0.05) shorter (57.00±2.81 and 61.20±3.11 days) than the control group (104.00±20.22 days). Thus, the Ovsynch and Ovsynch + PRID protocol can be successfully used to induce fertile estrus in postpartum anestrus buffaloes.

Conjugated linoleic acid (CLA) is a collective term for the positional and geometric isomers of a conjugated diene of linoleic acid (C18:2, n-6). The aims of the present study were to evaluate whether levels of hepatic α-tocopherol, α-tocopherol transfer protein (α-TTP), and antioxidant enzymes in mice were affected by a CLA-supplemented diet. C57BL/6 J mice were divided into the CLA and control groups, which were fed, respectively, a 5 % fat diet with or without 1 g/100 g of CLA (1:1 mixture of cis-9, trans-11 and trans-10, cis-12) for four weeks. α-Tocopherol levels in plasma and liver were significantly higher in the CLA group than in the control group. Liver α-TTP levels were also significantly increased in the CLA group, the α-TTP/β-actin ratio being 2.5-fold higher than that in control mice (p<0.01). Thiobarbituric acid-reactive substances were significantly decreased in the CLA group (p<0.01). There were no significant differences between the two groups in levels of three antioxidant enzymes (superoxide dismutase, glutathione peroxidase, and catalase). The accumulation of liver α-tocopherol seen with the CLA diet can be attributed to the antioxidant potential of CLA and the ability of α-TTP induction. The lack of changes in antioxidant enzyme protein levels and the reduced lipid peroxidation in the liver of CLA mice are due to α-tocopherol accumulation.

Introduction: The role of virgin coconut oil in the treatment of allergic rhinitis is controversial. Thus, the aim of the present study is to determine the effects of virgin coconut oil ingestion, in addition to standard medications, on allergic rhinitis. We also studied the side effects of consumption of virgin coconut oil. Methods: Fifty two subjects were equally divided into test and control groups. All subjects received a daily dose of 10mg of loratadine for 28 days. The test group was given 10ml of virgin coconut oil three times a day in addition to loratadine. The symptoms of allergic rhinitis were scored at the beginning and end of the study. Results:, the symptom score were divided into nasal and non-nasal symptom scores. Sneezing score showed a significant difference, however the score was more in control group than test group, indicating that improvement in symptom was more in control group. The rest of the nasal symptom and non-nasal symptom score showed no significant difference between test and control groups. Approximately 58% of the test subjects developed side effects from consumption of virgin coconut oil, mainly gastrointestinal side effects. Conclusion: In the present study, ingestion of virgin coconut oil does not improve the overall and individual symptoms of allergic rhinitis, furthermore it has side effects.

The actor/observer effect was examined by Storms in a 1973 study which manipulated perceptual orientation using video recordings. Storms' study was complex and some of his results equivocal. The present study attempted to recreate the perceptual reorientation effect using a simplified experimental design and an initial difference between actors and observers which was the reverse of the original effect. Female undergraduates performed a motor co-ordination task as actors while watched by observers. Each person made attributions for the actor's behaviour before and after watching a video recording of the performance. For a control group the video recording was of an unrelated variety show excerpt. Actors' initial attributions were less situational than observers'. Both actors and observers became more situational after the video replay but this effect occurred in both experimental and control groups. It was suggested the passage of time between first and second recording of attributions could account for the findings and care should be taken when interpreting Storms' (1973) study and others which did not adequately control for temporal effects.
