COMPARATIVE-EVALUATION OF FRIESIAN-SAHIWAL AND FRIESIAN-HARIANA HALFBREDS AT DIFFERENT MILITARY FARMS

Data consisting of first lactation and lifetime performance records of 1380 Friesian-Sahiwal (FS) and 690 Friesian-Hariana (FH) halfbreds ma intained at 6 military dairy farms were analysed, FS halfbreds yielded 271 kg more milk in first lactation than FH halfbreds at Agra, wherea s FS halfbreds produced 175 kg less milk than FH halfbreds at Lucknow. First lactation profit was negative in both genetic groups. FS gave m ore loss in first lactation than FH halfbreds at Ambala, whereas FH ha lfbreds gave more loss at Bareilly and Jhansi. The first calving inter val was longer in FS halfbreds al Bareilly and Meerut. FS halfbreds co mpleted more lactations than FH halfbreds at Bareilly, Jhansi and Meer ut. FS had longer herd life than FH halfbreds at Agra, Bareilly, Jhans i and Meerut. The FS halfbreds yielded more milk during life time than FH halfbreds at Agra, Bareilly, Jhansi and Meerut. FH produced more m ilk than FS at Lucknow. FS halfbreds yielded more profit in life than FH halfbreds at all farms except Lucknow. The performance of the two g enetic groups differed at different farms.
