The aim of the current study was to find out the relationship between leptin, progesterone, bodyweight with the onset of puberty in the ewe lambs.
Eight healthy weaned local breeds of ewe lambs at the age of 90 days were introduced in the study, Body weights were recorded, blood samples serum was collected and stored at -20°C until hormonal assays. ovaries and ovarian follicles were checked by ultrasound used to measure follicular diameter every two weeks until estrus was detected.
The result showed that the earliest estrus behavior was noticed at age 202 days. Significantly increased body weight was recorded during the trial times at p ≤ 0.05 Moreover leptin level elevated significantly coinciding with the age of puberty at p ≤ 0.05. Also, progesterone level was elevated significantly as the age of puberty at p ≤ 0.05. In addition to that the follicular diameter record a significant increase from day 160 till the end of the trial. Studying the correlation among, leptin, progesterone, and follicle diameter revealed a direct correlation with puberty and total weight body at pre-puberty days. In addition, a close positive direct correlation was observed between the level of progesterone and the diameter of the follicle with the level of the leptin as progressing age of puberty, and the increase in the diameter of the follicle with a rise in the level of progesterone.
The study concludes, was found a strong positive correlation among the studied parameters with a time of puberty in ewe lambs.

The objective of this study was todetect the percentage of Polymorph nuclear cells) PMNs (from the uterine smears using the local manufactured uterine cytobrush instrument, and to determine the echogenicity the intrauterine fluid byUltrasonography. Thirty (Arabian) repeat breeder mares were used. Animals were examined through rectal palpation and ultrasound. Mares were divided into 4 groups depending on the results of: 1) the amount of intrauterine fluid using ultrasound; 2) the endometrial samples were collected during estrus cycles, 3) the numbers of uterine epithelial cells and PMNs using locally manufactured cytobrush tool, 4) the number of lymphocytes. The results showed that the incidence of endometritis had significantly related to that age of the animals. The number of PMNs were significantly different between groups. The mean number of PMNs was 1.63±0.23, 3.34±0.18, 4.78±0.26 and 5.26±0.46 in G1, G2, G3 and G4, respectively. The echogenicity of the accumulated fluid in the endometrial lumen was significantly associated with the percentage of lymphocytes. The mean number of lymphocytes was 1.02±0.42 and 1.84±0.37%, in G3 and G4 respectively. This study concluded that the cytobrush technique is rapid, cheap, safe technique and easy to obtain samples from mare's uterus in the field. Consequently, Ultrasound and cytological techniques could be recommended for diagnosis of endometritis in mares.

Congenital or acquired abnormalities in genital tracts of ewes leading to sterility, which cannot easily to be identify by routine clinical examination. Reproductive tracts abnormalities regarded as a major causes lead to loss of sheep production. This study aimed to examine reproductive tracts in slaughtered ewes grossly and microscopically. This study was conducted on 270 genital tracts of non-pregnant ewes at Khanky slaughterhouse in Duhok province. Samples were collected within the period from September 2019 to March 2020. The results showed that 24.1% exhibited acquired abnormalities and 75.9% were exhibited normal. The rate of uterine abnormalities was about 3.3%, ovarian abnormalities comprised 17.8% and oviduct abnormalities were 3.0%. The most common pathological conditions of the uterus were endometritis at rate 2.2%, hydrometra (pseudopregnancy) and mummifies foetus at rate 0.4% and 0.4%, respectively. In the ovary, the common abnormalities were ovarobusral adhesion 14.4%, ovarian cysts 1.1% and Para ovarian cysts 0.4%. The abnormalities of the oviduct were uterine tubes obstruction 2.6%, followed by hydrosalpinx 0.7%. It is concluded that pathological lesions, such as endometritis, ovarian cysts and hydrosalpinx in ewes could result in infertility or sterility of the ewes leading to economic losses to farmers.
