ESE Hafez & B. Hafez • Controlled Reproduction in Cattle–Buffalo 1st Vol 1. CAB International, UK. Gordon I • Reproduction in Cattle By Peter and Ball • Google Scholar and other search engines 21-09-2020 5 Prerequisite to Understand • Thorough knowledge of Reproductive physiology - Sources, target and functions of all hormones • Application of the knowledge - For economic benefits - Increasing production - Enhancing reproductive efficiency - Reducing the cost of production and management 21-09-2020 6 Introduction to Biotechnology and its Recent Trends 21-09-2020 7 Theriogenology • Branch of Veterinary Medicine which deals with reproduction, - Physiology and pathology of male & female reproductive systems - Clinical practice of Veterinary Obstetrics, Gynecology, & Semenology 21-09-2020 8 Reproductive Biotechnology • Biotechnology The use of living organisms to improve, modify, or produce industrially important products or processes • Reproductive Biotechnology Reproduction-related biotechnologies Any Examples? 21-09-2020 9 Artificial Insemination (A.I.) • One of the early reproductive biotechnologies, • Permits the use of superior males for breeding purpose, • Semen from superior males is collected and used to inseminate large number of females, • Control of the Venereal diseases, • Endangered species, • Issues related with transportation and breeding, 21-09-2020 10 Estrus Synchronization • Bringing the randomly cycling females into one stage of cycle (estrus) - Prolonging the estrous cycle - Shortening the estrous cycle Question: How we can do this? 21-09-2020 11 Superovulation • Protocol used to make the females develop and ovulate more number of oocytes in mono-ovulatory animals - GnRH - FSH - PMSG Ques: Can you name the best source of gonadotropic hormones? 21-09-2020 12 Embryo Transfer (E.T) • Females with superior genetics are superovulated and their fertilized ova (in vivo or in vitro) are transferred to recipients, • Recipients are genetically less distinguished surrogate mothers. - Surgical - Non surgical 21-09-2020 13 In-Vitro Fertilization (IVF) • Fertilization outside the body i.e., in the laboratory, - Tissue culture medium - Modified Tyrode’s - Kreb’s-Ringer’s solution…..supplemented with sources glucose, lactate, pyruvate and albumin (Ham F-10) supplemented with blood serum • In-vitro maturation (IVM) 21-09-2020 14 Thanks for your attention 21-09-2020 21-09-2020 15
