Changes in Productive and Reproductive Performance of Indigenous Lactating Cattle Fed on Mustard Oil and Molasses Supplementation

Abstract

Eighteen lactating indigenous cattle were randomly divided into 3 groups of 6 animals (3 Gir and 3 Sahiwal) each on the basis of milk yield and lactation stage to see the effect of molasses and Mustard oil supplementation on production and reproduction performance. Cows were fed wheat straw, concentrate mixture and green fodder in the control group and additional 200 g of mustard oil and molasses was given in treatment groups. Experimental feeding was continued up to 90 days after 2 weeks of adaptation. Overall body weight change was higher in G2 (mustard oil supplemented) group and lowest in G1 (control) group. Statistically there was no significant difference in the average body weight change of indigenous lactating cattle between treatments. Overall BCS was higher in G2 (mustard oil supplemented) group and lowest in G1 (control) group however statistically there was no significant difference in the average BCS of indigenous lactating cow in between G2 and G3 though G1 differed significantly (P> 0.05) from G2 and G3 different treatment groups. Overall Dry matter intake (DMI) was higher for treatment group compared to control however; the values were statistically non-significant between the treatment groups of indigenous lactating cattle.Animals of G2 group had shorter postpartum estrus period followed by G3 group and G1 group respectively. The studied revealed that feeding of mustard oil and molasses had significant (P
