The aim of the present study was to buildup equation (s) for an intra-uterine fetal aging in Egyptian local sheep and she-goats breed using ultrasound. This study was carried out on a total number of 110 Baladi sheep and 74 she-goats under the field condition of Qalyubia governorate, Egypt. Ultrasound examination was conducted through trans-rectal...

Keywords The current study entails the data obtained from ultrasonography investigation of the reproductive statuses of ewe (n=232) and does (n=164) admitted to Meet Kenana, Veterinary Clinic, Tukh, Qalyubia governorate aiming to declare the contributing factors (species, season, body weight and age) impact their fertility. Pregnancy examination re...

This study aimed to assess the relation between the morphometric and histological attributes of the epididymis, and epididymal semen features in mature dromedary camels. The testes with the attached epididymis (n=50) were collected from adult camels along the rutting season from December to April. The separated epididymis was evaluated for weight a...

In times of increasing human population, more food is needed and camels are an ideal source. This work aims at providing an overview on diagnostic investigations, as brucellosis has an economic impact on the production and reproduction in camels. A number of 271 apparently healthy camels of both sexes at different ages were used in this study durin...

Brucellosis is a major infectious zoonotic disease affecting animal and human. In animal, the disease is causing great economic losses such as abortion, still birth as well as infertility in both male and female. A cross sectional study carried out from November 2016 to May 2017 to estimate the seroprevalence of brucellosis in sheep and goats in Be...

Query (Q) fever is an ubiquitous zoonosis caused by Coxiella burnetii. The present study was carried out to determine the prevalence of C. burnetii in apparently healthy sheep, goats and farm workers. Raw milk and serum samples were randomly collected from 200 sheep, goats (100 of each) and 30 farm workers from Qaluobia governorate, Egypt during 20...

Selected buffalo oocytes were matured in vitro on TCM-199 and incubated for either 16, 18. 22, 24 or 30 hours (Experiment, 1); on either TCM-199, Ham's F-10 or MEM media and incubated to 24 hours (Experiment, 2): TCM-199 supplemented with 10% of either FCS. EBS. DBS or PBS (Experiment, 3). Rates of maturation, fertilization, cleavage and embryo dev...

Ovaries from adult buffalo cows of unknown breeding history were collected from a slaughter House. They were transported into the IVF laboratory within 2 to 4 hours post-slaughter. Oocytes were left in the post mortum ovaries for 2,3,4,6 and 8 hours post-slaughter before oocyte collection (Experiment, 1). According to their morphology, ovaries had...

The matured oocytes were incubated in F-TALP medium and inseminated by using either fresh or frozen-thawed semen at a concentration of 2 x 10 6 sperm cell/ml (Experiment,1). Other matured oocytes incubated in F-TALP medium were inseminated by using fresh semen at sperm concentration of either 0.5, 1.0, 2.0, 3.0. 9.0 or 10 x l0 6 sperm cells/ml (Exp...

The current study was conducted to estimate the time needed for placental dropping and the effect of beta-blocker carazolol (Suacron, Praemix, Mannheim) on placental retention. Carazolol was injected to enhance the placental dropping and also as a prophylactic measure to minimize the incidence of retained foetal membrane in the she-camel. Normal dr...

SUMMARY A total number- of 307 female Newzealand White rabbits were used to study the relationship between the color of the vulva and the reproductive performance. using of A.I. technique, the conception rate, pregnancy rate and litter size were recorded. Four groups were classified according to the vulva color; congested. red, pink, purple and pal...
