AbstractTo find out the effect of reducing energy intake during dry period on milk production, udder health, and body condition, the experiment was conducted on 14 Jersey crossbred cows during whole dry period and continued up to 120 days of lactation. Reduction in energy intake was done during far-off period for each dry cow of treatment group as compared to control group. Statistically analyzed data revealed that overall significantly (P < 0.01) lower DMI and WI were recorded in control than treatment group. Overall significantly (P < 0.01) higher total milk production was found in treatment than control group. Overall significantly (P < 0.01) lower milk SCC, MCMT, pH, and EC were found in treatment than control group. Nonsignificant difference in milk fat, SNF, total solid, total protein, and fat:protein ratio was found. Overall significantly (P < 0.01) better quality milk (MBRT) was found in treatment than control groups. BCS during dry period and at calving was significantly (P < 0.01) different between groups. Significantly (P < 0.01) higher plasma NEFA concentration was estimated in control than treatment groups in all stages. No significant difference was found for plasma concentrations of glucose, urea, and total protein. The coefficients of correlation indicated significant (P < 0.01) correlation among BCS, milk production, milk SCC, MCMT, pH, and EC. It can be concluded that reducing energy intake during far-off dry period can lead to achieve optimum BCS at calving. Suitable BCS at calving was beneficial to get higher milk production with improved quality, better maintenance of udder health and body condition of Jersey crossbred cows at tropical lower Gangetic region.

Effect of Dry Period Duration on Udder Health, Milk Production and Body Condition of Jersey Crossbred Cows at Lower Gangetic Tropics

“…Since cows of 2 nd group having prolonged DPD (>60 days), could not maintain optimum BCS at calving, so during post calving period higher negative energy balance (NEB) was found which might had led to impaired immune function and increased risk of intermammary infection (IMI) which ultimately resulted in higher somatic cell count in 2 nd group. Findings of other workers (Singh et al 2020a) supports the results of present study which indicates that udder health problems were encountered in high BCS cows as compared to optimum BCS cows. Proper BCS cows showed significantly lower SCC.…”

Constraints and Way Forward for Boosting Income from Dairy Farming in India: A Review

“…Smallholder dairy farmers of India consider dairying as their main source of income. Dairy farming is the main source of revenue for India's smallholder dairy farmers [8]. India produces far more milk than the United States, which is the world's second-largest producer [9].…”

Influence of pre and postpartum alpha-tocopherol supplementation on milk yield, milk quality, and udder health of Jersey crossbred cows at tropical lower Gangetic region

“…However, in a farm experimentation, Singh et al . [ 1 ] found that Jersey crossbred cows of this region may produce 12.70 kg/day/cow under organized conditions. Duffield et al .…”

“…Improvement in milk yield, milk quality, body condition, and udder health status can be achieved with proper nutrition and management conditions during the initial and later lactation period [ 1 , 2 ]. Adoption of good animal management may improve the overall production and health performance of dairy cows in tropical climate [ 3 - 5 ].…”
