Biotechnology Reproduction and Biodiversity Indicators in Buffalo Breeding

Abstract

Biodiversity is the basic indicator, which expresses the durability and stability zone in direct relationship with the environment and life. Biodiversity monitoring both quantitatively and qualitatively puts us in contact with reality environment and its stability, because biodiversity is constantly changing. Only by measuring the biodiversity we can perceive the sudden chances, which influence directly our life in order to interfere with redesigning the media by ecological reconstruction. The application of biotechnologies to buffalo breeding is paramount to remedy the existing situation. The most numerous Romanian buffalos are the Carpathian type, with valuable gene resource, well adapted to the cold climate for buffalo. Results of artificial insemination in this species are influenced by the quality of semen used. We know that there are periods in which sperm are immobile, so it is important to test the ability of sperm fertilized. This test can be performed in vitro using direct or indirect methods. Utilization of Polamski scale principle remains present, but can be improve and combine with Milovanov resistance and “in vitro” capacitating methods. For determination of fertilizing power we use “in vitro” capacitation methods: direct method, indirect method and “swim-up” technique who are obligatory in E.U. We use this tests because Polamski scale can’t be applied, knowing that an immobility of buffalo semen in some conditions is a characteristic of this semen, semen that can be recovery on the normal parameters. Milovanov resistance test have restricted efficiency because NaCl solution have a negative effect over the sperms. Semen charges testing with these new methods they present a good fertilizing power. This test is easier to realize and takes of decision is faster.
