Reproductive Performance and Economic Estimates of Pasundan Cattle Induced with Prostaglandins and Hormone Releasing Gonadotropins

Abstract

Twenty Pasundan heifers were used in this study to determine the economic estimation of Pasundan cattle induced with prostaglandins and gonadotropin-releasing hormones. The cows were randomly divided into two groups of 10 each. The first group came from breeders who are members of the Rundayan Sawargi Group, Karya Mukti Village, Cibalong District, Garut Regency and the second group of cows came from the Mekar Tani 2 Livestock Group, having their address at Singasari Village, Jonggol District, Bogor Regency. All cows were injected with prostaglandins (PGF2α, dinoprost tromethamine) with a dose of 5 ml/head intramuscularly 2 (two) times with an interval of 11 days, and on the 9th day was injected with gonadotropin realizing hormone (GnRH, gonadorelin) of 2.5 ml/head intramuscularly. Cows in heat were artificially inseminated 2x with an interval of 6 hours. The variables observed were the percentage of birth rate, childbirth weight and body weight gain up to 120 days of age, percentage of calf mortality to 120 days of age, profit, and B/C ratio. The data were processed by analysis of variance and used descriptive methods. The results showed that cows in the Garut region had an average calving rate (birth rate) of 90%, birth weight of calves 21.51 ± 0.71 kg, body weight gain 0.60 ± 0.5 kg/head/day, mortality 0%, profit Rp. 26,495,000, - and B / C ratio 1.1. better than the Bogor area with a birth rate of 87.5%. Birth weight 19.95 ± 2.02 kg, body weight gained 0.55 ± 0.5 kg/head/day, mortality 0%, Profit Rp. 12,120,000, -and B / C ratio 0.51. It was concluded that the economic estimation of Pasundan cattle induced with prostaglandins and gonadotropin hormones in the Garut area is better than the Bogor area, with an increase in income of 218.23% per 13 months.
