Abstract

Eighteen Gir cows of similar body weight and stage of lactation were randomized into three groups of six each and were offered one of the dietary treatments (T1: Green jowar@5 kg per day per animal and ad lib feeding of wheat straw, T2: Green jowar and wheat straw mixed in the ratio of 30:70 offered ad libitum and T3 : 4% urea treated wheat straw offered ad libitum) along with concentrate mixture to meet protein requirement for a period of 70 days. Body weight losses in experimental cows in all the groups were non-significant. T2 group cows produced significantly (p<0.01) higher milk and FCM yield and also consumed higher DMI with narrow R:C ratio than control and T3 group of cows. However, cost of feeding was significantly ( p<0.01) lower in urea treated wheat straw offered group of cows compared to control with 135 per cent higher return over feed cost.

Abstract

The prostaglandin and its synthetic analogue are considered as drug of choice in reproductive management. A total of twenty Jaffrabadi buffaloes with reproductive disorders were selected from cattle breeding farm, Junagadh. All twenty buffaloes (Group I) were treated with single dose of Prostaglandin (synthetic analogue, clostrinol, 2 ml) while the animals which did not respond (Group II) to first injection of Prostaglandin were subjected to second injection of Prostaglandin 11 days after first treatment. A total of six animals (30%) responded to first dose of PGF₂α, while eight animals (57%) responded to second dose of PGF₂α. The mean time required for induction of heat in first and second group was 70.24 ± 1.44 hrs and 56.86 ± 1.96. The mean duration of estrus proper in first group was 19.18 ± 0.69 hrs, while in second group the mean duration was 16.13 ± 0.42 hr. The conception rate in the present study was 43.05 per cent for the first group of animals and 49 per cent for the animal that were treated with second dose of PGF₂α. In conclusion, administration of PGF₂α at eleven days interval causes faster heat induction and better conception rate.
