چکیده
|
Cattle in pakistan have traditionally been raised for producing bullocks except breeds such as sahiwal and red sindhi which are established milch breeds. general production system is low-input extensive system with crossbreds mainly raised under intensive high input system in the cattle/buffalo colonies to sustain the demand of milk especially during summer, the slump period in buffalo milk. although, draft breeds are losing utility yet, it will take many generations before they are replaced due to mechanization. efforts, however, are needed for their in situ conservation and directional selection towards beef. institutional records indicate weak genetic control for most of the economic traits but accurate recording of performance and pedigrees can improve these estimates. breeding policy guidelines need adoption in letter and sprit to conserve various breeds. institutions established for breed improvement need to be restructured for achieving the goals. adequate diversity in performance and adaptability can be exploited for actual improvement accruing to conservation and development of indigenous cattle resources.
