REPRODUCTION
It also accomplished the thermal resistance test (quick TTR), where the sample is placed in a water bath at 46 º C for 30
minutes to then be examined.
Field Practices
AI in buffaloes is an effectible reproductive biotechnology; however it requires the effective and continuous supervision
of a Veterinarian with specific training in buffalo reproduction. Veterinary services must be offered as a task force. It is
important to figure out that one of main constrain of the use of AI in buffaloes is the absence of Veterinary services and
continuous supervision in the program. Thus, the main impediments to the use of AI in buffaloes in the Brazil as
elsewhere in Latin America, at the present time are inadequate nutrition, poor management and handling, a lack of
rational breeding policies, and diseases (not necessarily all occurring simultaneous) and difficulty in liquid nitrogen
supply. The AI in buffaloes as technology is quite feasible in Latin America condition and the fertility rates have achieved
more than 80 per cent of conception rates, when used throughout correct technical criteria.
CONCLUSION AND RECOMENDATION
The AI in buffalo is a concern for each regional country and reflects the growing interest in the species as an important
constituent of local agriculture and substantial contributor to country’s economy. The AI programme goes side by side
with improvement of the management, nutrition, diseases control with an overall impact on reproduction and milk /
meat production. In some areas, the supply and cost of liquid nitrogen can limit the use of this technique. Moreover, it
is the only alternative to avoid inbreeding which is affecting some buffalo breeds in this continent. The technology has
unmistakable advantages for animal husbandry but unfortunately may be disadvantageous if used uncontrolled leading
to inbreeding and lethal malformations. Thus, it is necessary to establish efforts to discuss such problems at international
level in order to avoid the dissemination of many of these inheritance defects. This biotechnology is quite feasible in
buffaloes and the fertility rates have achieved more than 80 per cent of conception rates, when used throughout correct
technical criteria. On this concern it seems that a wide discussion among buffalo breeders and technicians should be
established to find out a way to introduce “new blood” in the form of semen, from selected animals from India and
Pakistan.
