Objectives

General: To provide the student with information related to reproductive management and clinical equine and farm animal theriogenology.

After completion of the program, students should be able to

Ruminants:
• Perform a BSE of the male (clinical examination, semen collection and evaluation, libido testing)
• Surgical castration
• Vasectomy and epidydectomy
• Pregnancy diagnosis in small ruminants(ultrasound)
• AI in the ewe (cervical)
• Estrus synchronization in ewes

Optional: IVF and embryo cryopreservation

Equine:
• Estrus detection
• Gynecological examination of the mare
• Clitoral and endometrial collection of samples
• Execution and interpretation of endometrial cytology
• Interpretation of reproductive ultrasonographies
• BSE of the stallion (external genitalia, semen collection and evaluation)
• Artificial insemination
• Chilled semen processing

Optional: embryo collection and transfer; embryo freezing

Swine:
• Pregnancy diagnosis (ultrasonography)
• Collection and evaluation of semen
• Artificial insemination
• Surgical castration of the boar

Program

Bovine.
Reproductive management of beef cattle: management of replacement heifers, age at first breeding, breading season vs year-round breeding, early vs. late weaning. National systems of production with imported and native breeds.
Nutritional needs of beef cattle during the post-partum, pregnancy lactation and pre-partum.
Genital surgery of the bull: castration, epididectomy, vasectomy, penile tumor removal, penile-prepuce translocation, rupture repair in penile hematoma.
Parturition and dystocia. Stages of labor and factors causing dystocia. Methods to prevent dystocia. Management of dystocia: anamnesis, restrain of the cow, examination, mutation of abnormal presentation, position and posture of the fetus. Forced extraction, fetotomy and C-section.  

Small ruminants.
Characteristics and manipulation of the estrous cycle: seasonality, male effect, prostaglandins, progestagens and gonadothrophins. Light manipulation and melatonin.
BSE of the ram, semen collection and evaluation. Surgical castration, vasectomy and epididectomy.
Pregnancy diagnosis: abdominal palpation, ultrasonography, radiology and biological tests. Manipulation of the estrous cycle: differences between the ewe and the doe. Artificial insemination: cervical and laparoscopic. Embryo collection and transfer. Embryo freezing. Sheep breeding strategies, lambing management and neonatal care.
Reproductive diseases and periparturient pathologies of the ewe. Native breeds, and main reproductive systems of production.

Porcine.
Reproductive physiology and endocrinology of boars and sows. Semen collection and evaluation and artificial insemination. Induction of estrus and control of the estrous cycle. Diagnosis of pregnancy. Reproductive managements programs for porcine, including semi-extensive national systems of production.

Equine
The estrus cycle and characteristics of the vernal transition. Methods to anticipate the breeding season. Estrus detection and reproductive management. Clinical examination of the pregnant and non-pregnant mare. Collection and interpretation of endometrial cytology and microbiology and of endometrial samples (biopsy). Management of twin pregnancies. Venereal diseases of the horse. Semen collection and evaluation. Semen refrigeration and freezing, and artificial insemination. Management of embryo transfer programs. Embryo cryopreservation. BSE of the stallion.

Teaching methods and learning activities

Two-hr lectures on the different subjects (15 weeks), with particular incidence on the description and discussion of clinical cases. Three-hour practical/clinical classes are given to smaller groups of students, either at the teaching farm (horses - 14 weeks) or in Abóbada Experiment Station (small ruminants, swine, beef cattle - 20 hrs).

Evaluation Type

Distributed evaluation with final exam

Calculation formula of final grade

Final grade is calculated adding the following grades: A) written (exam max. 12 points), B) participation in the practical classes on beef cattle, small ruminants and swine reproductive technologies at Herdade da Abóbada Experiment Station (3 points),  C) assistance and participation in lectures (max. 1.5 points); D) frequency of clinical classes and completion of basic procedures (max. 3 points), E) extra experimental or clinical project (0.5 points). A mnimum number of rotations in dairy cattle and equine theriogenology ambulatory services is required. 

Examinations or Special Assignments

Projects on equine or dairy cattle theriogenology or in in vitro fertilization or gametes and embryos cryopreservation.
