The present study pertained to records on milk production and milk constituents of 259 Sahiwal cattle with 600 lactations spread over a period of 10 years from 2001 to 2010, collected from Dairy Cattle Breeding division of National Dairy Research Institute, Karnal, Haryana. To study the effect of various genetic and non-genetic factors on milk yield and milk constituents traits, mixed model least square analysis was used for analysis of data. Overall least square mean for all lactation traits of total milk yield (TMY), milk yield in 305 days or less (305MY), lactational average fat % (LFA) and lactational average solid not fat % (LSA) were 1880.39 ± 73.82 Kg, 1782.97 ± 68.37 Kg, 4.71 ± 0.01 % and 8.81 ± 0.01 % respectively. Analysis of variance showed that the differences were statistically significant for the effect of sire on TMY and 305MY; period on all the traits except TMY; parity on 305MY. However the effect of season of calving was not found significant on all the traits.

Data on husbandry and breeding practices were collected from 96 sheep keeping farmers of villages from coastal region in Bangladesh during May 05, 2016 to June 07, 2016. Many farmers (66.70%) did not provide water to their sheep and mainly green grass (100%) and tree leaves (96.90%) were used for feeding the sheep. Many of the farmers did graze their sheep from dawn to dusk. Majority of the sheep farmers (63.50%) employed workers to take care of their sheep and there were two types of farmers. All farmers took bath of their sheep and majority of the farmers vaccinated (53.10%) and used anthelmintics (53.10%) regularly. All farmers were keeping sheep for meat purpose. Traditional natural mating system (95.90%) followed by the sheep farmers at study sites, where rams were allowed to mate with a heated ewe without considering the relationship between ram and ewes. In this traditional mating system at study site, farmers allowed the ram to mate with half sibs, full sibs, also allowed th...

A total of 210 Holstein Friesian (HF) × Local crossbred cattle were examined to collect data like, test day milk production (MT), peak milk production (PM), lactation period (LD), green grass used the day before test milk production (GG), cost involved to feed the cow with concentrate feed on the day before test milk production (CP), age, body weight of cows (BW) and ancestry of test cows to define the grade. The data were collected using a pre-structured questionnaire at the villages of Noakhali district in Bangladesh during October to November 2016.The effect of grades, age, body weight, concentrate feed and green grass on milk production were evaluated. To study the effects, Duncan's Multiple Range Test and Pearson's correlation coefficient were performed using the Statistical Package for the Social Sciences. Positive correlation of MT with CP (0.794) and GG (0.453) were estimated. Ages of cows did not affect MT, PM and LD significantly. In grade two, the highest, MT (18.75±2.62 liter/cow/day) and PM (20.75±2.62 liter/cow/day) were reported for body weight group 3 while, the longest LD (219.88±0.47) was reported under body weight group 2. However, under grade three in body weight group 3, MT, PM and LD were 15.57±0.78 liter/cow/day, 18.00±0.78 liter/cow/day and 218.79±0.80 days/cow, respectively. Present study might be suggested that body weight group 3 under grade three was better for MT and PM while, body weight group 2 was better for LD but to come up with final decisions in this regard, further study addressing more numbers of crossbred cows with defined exotic blood percentages under different grades, seasons of calving, parity, feed and water management, housing, healthcare and farmers socioeconomic status would be advisable. Finally, it might be indicated that grades, bodyweight groups, CP and GG affected milk production at the villages of Noakhali district in Bangladesh.
