Abstract:
The objective of the present study was to investigate the effect of nano zinc oxide in comparison to inorganic Zn on milk yield, udder health and protein profile in Sahiwal cows during transition period. A total of 24 Sahiwal cows were randomly divided into four groups (T0 (control), T1, T2 and T3) with 6 animals in each, based on parity (2-5 parity). Basal diet was followed in all the groups whereas in groups T1, T2 and T3 additional 40 ppm Zn from ZnO, and 20 and 40 ppm Zn from nano ZnO was supplemented, respectively. Results indicated that significant (P≤0.05) difference was observed in milk yield at fifth fortnight; although T2 and T3 group does not have significantly differed. The mean value of milk yield was significantly (P≤0.01) higher in T3 group compared to other groups; however, there was no significant difference between T1, T2 and T3 groups. Milk SCC was significantly (P≤0.01) lower in T3 group compared to other groups; however, there was no significant difference between T1 and T2 group. Overall mean of milk pH of 75 days of lactation period in all groups differ significantly (P≤0.01) and was significantly (P≤0.01) lower in T3 group compared to other groups; however, there was no significant difference between T1 and T2 group. The total protein and globulin concentration during prepartum period was lower compared to postpartum period among all the groups. The postpartum mean concentration of total protein and albumin in T3 group were found highly significant (P≤0.01) compared to other groups. Mean concentration of serum total protein was significantly (P<0.05) higher in both T3 and T2 groups; however, T2 and T3 group does not have significantly differed. Mean albumin conc. was significantly (P<0.05) higher in T3 group; however, T0 and T2 group does not have significantly differed. The prepartum mean of globulin conc. in treatment groups was found highly significant (P≤0.01). However, treatment groups do not have significantly differed. Significantly (P<0.01) higher in mean concentration of serum globulin was found in T2 group compared to other groups. The result revealed that animals supplemented with 40 ppm of nano Zn has shown better performance compared to animals of other groups.
