Effect of Dietary Supplementation Area Specific Mineral Mixture along with Hormonal Interventions on the Performances of the Anoestrous and Repeat Breeding Crossbred Cattle

摘要

A study was conducted to assess the effect of dietary supplementation of area specific mineral mixture and hormonal therapy on the reproductive performances of anoestrous and repeat breeder crossbred cattle at Nimapara block of Puri district, Odisha,India. A total of 60 animals (40 cows, 20 heifers) were selected and were randomly distributed into four groups of 15 animals each (containing both aiioestrus and repeat breeder), experiment was continued for 60 days. Animals of the Group I (control)werefed straw based diet along with concentrates as practiced by the farmers and received no dietary or hormonal intervention. However, animals of group II received dietary supplementation of an area specific mineral mixture at 50 g/animal/d, Hormonal protocols like double synch and estra double synch along with area specific mineral mixture at 50 g/d/animal were tested on animals in group III and IV, respectively. Results revealed significant (P<0.05) improvement in growth and reproductive performance intreatment groups as compared to control group. Thus, supplementation of area specific mineral mixture along with hormones gave better results in augmenting reproductive disorder in crossbred animals.
