Effects of Feeding Castor Beans on Oestrous Cycle and Subsequent Fertility of the Sudan Desert Ewes (Hamari)

This study was carried out to determine the length of the oestrous cycle and progesterone (P4) profile during the oestrous cycle of the Sudan Desert ewes (Hamari) and to investigate effects of feeding castor beans on the oestrous cycle and subsequent fertility of the treated ewes. Experiment 1 was conducted to determine the length of the oestrous cycle and P4 profile during the cycle. Ten...

Approaches for Treatment of Retained Placenta in Cross-bred Dairy Cows and their Effect on the Postpartum Period

في هذه الدراسة تم استخدام 231 بقرة هجين (بطانة X فريزيان) لتحديد نسبة حدوث احتباس ا لمشيمة بولاية الخرطوم و أثرها علي الصفات التناسلية بعد الولادة ولمقارنة معدلات نجاح ثلاث طرق للعلاج في استعادة المعدلات الطبيعية للخصوبة في الابقار المصابة. كما تمت دراسة أثر العمر, عدد الولادات، وزن الجسم، نسبة الدم الاجنبى والموسم علي درجة الاستجابة للعلاج في استعادة الخصوبة لمستوياتها قبل الولادة. تم تقسيم...

Postpartum Interval Of Some Local Breeds Of Cows In South Darfur State - Sudan

In the present study, the length of postpartum interval (PPI), the effect of season and gonadotropin (GnRH) injection on the length of PPI were studied in some local Sudanese dairy cows native to South Darfur State namely Fellata, Kenana and cross-bred. Furthermore the influences of body condition score (BCS) and parity on PPI were also investigated. In experiment 1 a total of 59 dairy cows...

Factors influencing postpartal reproductive traits of crossbred dairy cows in the Sudan

The purpose of the present study is to determine postpartal reproductive traits such as the time required for complete uterine involution, commencement of ovarian activity, first postpartum oestrus, the open period, number of services per conception and the calving interval. Moreover, factors affecting these parameters such as, age, parity, body weight, milk yield at the first three months,...

Study of Surgical Intrauterine Artificial Insemination Efficiency in Sudanese Desert Sheep

Artificial insemination in sheep is currently limited by the poor fertility obtained following the traditional methods of insemination (vaginal artificial insemination, cervical artificial insemination and transcervical artificial insemination). The reduced fertility after artificial insemination can be due to the difficulty of traversing the cervix and the cervical trauma caused by the...

Reproductive performance of Desert Goats under semi-intensive system in the Sudan

This study was conducted on Desert goats to investigate some reproductive traits including puberty age, oestrous cycle length, oestrous duration, gestation period, post partum and the efficacy of different hormonal treatments (PGF2ل and progesterone with or with out eCG) in inducing and synchronization oestrous cycle, to improve the reproduction efficiency, and to evaluate some reproductive...

Pubertal Traits In Male And Female Sudanese Desert Sheep

The objective of the present study was to study pre and post pubertal ‎development of reproductive traits, and to prescribe criteria for selection of ‎young ewe and rams for breeding purposes.‎ In the first part of this study, 8 ram lambs in their first month of age and ‎average body weight of 8.5 kg were chosen to be used for determination of ‎age at puberty and selection criteria for...

No Abstract

Reproductive Performance Of Nubian And Cross-Bred Does Following Oestrous Synchronization And Artificial Insemination With Fresh Diluted And Frozen Semen

In this study experiments were conducted. Experiment (1) using a total of 105 does (70) Nubian and 35 Crossbred does (Nubian X Saanen), this experiment was carried out to determine the best approach for oestrous synchronization, to improve the reproductive efficiency based on the oestrous response, pregnancy rate, kidding rate, twining rate, fecundity and prolificacy. The animals were grouped...

Effect of Season on Sexual Behaviour, Semen Quality and Fertility of Nubian, Saanen and Crossbred Bucks in Sudan

The present study was conducted to investigate the effect of season on reproductive traits of Saanen bucks in comparison to Nubian and Nubian x Saanen Crossbred bucks. The study was carried under the normal climatic conditions of Sudan, in order to provide necessary data to use these bucks in genetic improvement programmes, using artificial insemination technique.  Eleven mature...
