Abstract
The aim of the present study was to demonstrate the effect of oral administration with Shatavari (Asparagus racemosus) on milk yield, raw milk constituent indices and fertility of crossbred cows during summer season. Twenty healthy lactating crossbred cows with a close date of calving were randomly divided into two equal groups for control group (CG; n = 10) and supplemented group: Shatavari root powder 50 gm/cow/d (SG; n = 12) from 7 days post partum (dpp) until 90 dpp. Statistically analyzed data revealed that fortnightly milk yield significantly (P<0.005) increased from 45 to 90 dpp was found in the SG (10.735 to 12.396 kg/day) compare to the CG (9.802 to 10.541 kg/day). Differences in the fortnightly raw milk composition related to percent of milk fat, milk protein and milk lactose of both CG and SG cows were non-significant (P>0.005), but only fortnightly percent of milk solid not-fat from 45 to 90 dpp in SG cows (9.254 to 9.446%) than over to CG cows (8.877 to 8.999%) and percent of milk total solids from 60 to 90 dpp cows in SG (13.078 to 13.727%) than that cows in CG (12.617 to 12.648%) were significantly (P<0.005) higher. Occurrence of first post partum estrus decreased (P<0.005) in supplemented Shatavari group (SG: 52 dpp) cows compared to control group (CG: 77 dpp) cows. In this study, it was observed that the overall conception rate was higher (P<0.005) in SG: 60% (cows pregnant: 6/10) and lesser in the CONT-group: 20% (cows pregnant: 2/10). The results of this study indicated that oral administration with Shatavari (Asparagus racemosus) increased the milk yield, raw milk solid not-fat, milk total solids and improved fertility of crossbred cows.
