Description |
The present research work entitled Study of Muzzle Printometry in relation with production potential in Sahiwal Cattle was undertaken with the following objectives. 1) To obtain muzzle print of Sahiwal cows and calculate ratio between muzzle characteristics 2) To collect data on total milk yield of 3 to 5 lactations of Sahiwal cows 3) To study correlation between ratio of muzzle characteristics and average lactation milk yield of 3 to 5 lactations of Sahiwal cows The muzzle prints and the data on milk production up to fifth lactation of 104 Sahiwal cows were noted. The muzzle measurements and muzzle characteristics of muzzle prints were recorded. The correlation between muzzle characteristics; muzzle measurements, their ratio and the average lactation milk production of Sahiwal were determined. The correlation between muzzle measurements, muzzle characteristics their ratio and average lactation milk production of Sahiwal cows was studied by dividing the number of cows in to four groups on the basis of lactation milk production as 1100-1500 liters (29 cows); 1500-1800 liters (59 cows); 1800-2100 liters (16 cows) and 1100-2100 liters (104 cows) respectively. The central length of the muzzle prints of Sahiwal cows were positively (0.486437) correlated and highly significant with the average lactation milk production (1100-1500 liters). It concludes that the Sahiwal cows measuring maximum central length on the muzzle print produced more milk per lactation and vice versa. The basal length of the muzzle prints of Sahiwal cows were positively (0.556359) correlated and highly significant, whereas the ratio of upper length and basal length (-0.59569) was also highly significant but negatively correlated with the average lactation milk production (1800-2100 liters). It concludes that the Sahiwal cows measuring maximum basal length on the muzzle print produced more milk per lactation and vice versa. However Sahiwal cows produced more milk when the ratio among upper length and basal length of muzzle prints was small and vice-versa. The number of beads (-0.66069) and ridges (-0.33494) on the muzzle prints of Sahiwal cows were negatively correlated and highly significant with the average lactation milk production (1100-2100 liters). It concludes that the Sahiwal cows measuring less number of beads or ridges on the muzzle print produced more milk per lactation and vice versa. |
