Colostrum Production Traits, Its Association With Milk Production Traits And Prediction Of Part Lactation Milk Yield In Red Sindhi Cow

SAMEER ASHOK DHAGE

Abstract


Four hundred and twenty four records of one hundred and thirty seven ‘Red Sindhi cow’ for colostrum production traits and fortnight milk production traits along with parity, period of calving, season of calving, gestation period group, dry period group and previous lactation milk yield group for the period 1961-2003 were collected from Department of Animal Husbandry and Dairy Science, College of Agriculture, Pune-3. Least square analysis (Harvey, 1976) was carried out to assess influence of parity, period of calving, season of calving, gestation period group, dry period group and previous lactation milk yield group on different traits under study. The overall least square means of CYA 1, CYA 2, CYA 3, CYA 4 and CYU 4 were 3.85 ± 0.10, 4.90 ± 0.10, 5.38 ± 0.10, 5.74 ± 0.10, and 19.88 ± 0.34 kg, respectively. The overall least square means of FMYU 15, FMYU 30, FMYU 45 and FMYU 60 days were 100.28 ± 1.43, 216.35 ± 2.98, 328.11± 4.36 and 432.11 ± 5.68 kg respectively. The cows calved in 4th parity performed better for colostrum production and fortnight milk production. The cows calved in period 2 performed better for all production traits except FMYU 45 and FMYU 60. The cows included in 4th group of previous lactation milk yield performs better for all production traits than 1st group of previous lactation milk yield. Non-significant differences due to season of calving, gestation period and dry period were observed on all traits under investigation.
