ABSTRACT

The data on weekly test day milk yield of 411 HF x Deoni crossbred having 838 weekly test day milk yield were collected from records maintained at Cattle Cross Breeding Project, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani (Maharashtra) over a period of 38 years (1977 to 2014). The least squares mean of weekly test day milk yield were estimated by considering effect of period of calving, season of calving and age at first calving group. The overall mean weekly test day milk yield varied from 1.35 ± 0.08 kg to 7.52 ± 0.08 kg recorded during 43rd and 6th week, respectively. The period of calving exerted significant (P < 0.01) influence on all 43 weekly test day milk yield. The season of calving had significant (P < 0.05) influence on WTDY5 to WTDY9, WTDY11 to WTDY13 and WTDY42 and WTDY43. However, non-significant effect observed in WTDY1 to WTDY4, WTDY10 and WTDY14 to WTDY41. The variation due to age at first calving group was significant (P < 0.01) in WTDY3 to WTDY5 and, non-significant in rest of the weekly test day milk yield.
