BookPublisher: 1999Subject(s): Department of TheriogenologyDDC classification: 0693,T Dissertation note: The main aim of the present study was to observe the economical impacts of artificial insemination with specific reference to the productive and reproductive performance of the local bred and Holstein Friesian cross bred cattle in Bannu region. The interaction of some productive and reproductive parameters had been studied. The outcome of the present study in respect of various parameters of productive and reproductive performance are summarized as below:
1. The mean for age at maturity in Holstein Friesian crossbred and local bred cattle were 610.3, 878.7 days, respectively. The difference calculated was 268.4 days. The mean for age at first calving in holstein Friesian and local bred were 970.3, 1244.6 days, respectively. The age at maturity and age at first calving was highly significant (P < 0.01).
2. The mean for conception rate in Holstein Friesian crossbred and local bred cattle were 15%, 62%, 23% and 14%, 70%, 16%, on 1st, 2nd and 3rd insemination, respectively. There was significant difference in conception rate of both the breed.
3. Calf survival for local bred averaged 68.5 days while for Holstein Friesian crossbred averaged 81.5 days, respectively. Again there is significant difference between the twq breeds.
4. The means for calving interval in Iloistein Friesian crossbred and local bred cattle were 393.3, 418.3 days, respectively. The difference was 28 days, which is significant (P<0.05)
5. The mean for the dry period in Holstein Friesian crossbred and local bred cattle were 89.3, 152.6 days, respectively. The difference was 64 days, which is highly significant (P<0.01).
6. The mean for milk production in Holstein Friesian crossbred and local bred cattle were 2404.08, 1173.12 litres/lactation.The difference was 90 days, which is highly significant (P < 0.01).
The findings of this study indicate that the productive and reproductive potential of Holstein Friesian crossbred is better than the local bred cattle. The productive potential of local cattle can be increased by using exotic semen of genetically superior sires, through intensive management and with effective disease control programme.
