Abstract

The study was aimed at scoring the body condition of Bali cows and its effect on thereproductive status. It was conducted in 14 smallholder farms in Bantaeng, South Sulawesi Province,Indonesia. A total of 64 Bali cows were involved in the study. All cows were subjected to bodycondition scoring (BCS; scale 1 - 9) and then clinically examined for reproductive status. The resultsof this study showed that most of cows had lower BCS (68%) and only 32% had BCS 5 or greater. Aproportion of cows with parities 1 and 2 were 61%, higher than parities 3 and 4; 28% and parity 5 orgreater; 25%. This study also noted that proportions of cows pregnant, cyclic and anestrous were25%, 9%, and 66%, respectively. Interval from calving (mean ± SD) to conception of these Bali cowswas relatively longer 191.3 ± 115.7 days and it expected calving interval of the cows approximately476 days. In conclusion, the Bali cows exhibited lower reproductive performance and lower BCS was the contributory factor.    Key Words: Bali Cows, BCS, Reproductive Status, Reproductive Performance

Abstract

The objective of this study was to evaluate the response of ovaries in estrus synchronizationprotocol using GnRH-PGF2α based protocol combined progestin in a herd with tie-stall housing system.A total of 20 Holstein Friesian cows at different stages of estrus cycle in a dairy herd were enrolled inthe present study. The cows were randomly allocated into two treatment groups; with and without CIDR(Controlled internal drug release) insertion. All cows received 100 μg of GnRH I.M. at the beginning ofthe treatment (d 0) without regard to the stages of the estrus cycle followed by 25 mg PGF2α IM 7dayslater. Cows in CIDR group were inserted CIDR into the vagina at the time of GnRH administration andwere removed on the day of PGF2α administration. estrus signs were checked twice daily starting onday-2 after initiation of the protocol, except cows in CIDR group the estrus signs were checked startingon day-8 of the protocol. The animals showing estrus signs were noted. Blood samples were collectedfrom all animals on the days of GnRH and PGF2α treatments and on day-10 after initiation of protocolfor progesterone concentration. The results of this study showed that 30% animals in cows withoutCIDR insertion showed estrus signs prior to PGF2α injection. Involving CIDR to synchronized estruswith GnRH-PGF2α based protocol avoided the occurrence of premature estrus and maintained highprogesterone concentration on the day of PGF2α administration. It is concluded that ovarian responseafter involving CIDR in the protocol for estrus synchronization especially using combination of GnRHand PGF2α were much effective to synchronize the initiation of estrus in dairy cows. Likewise, the useof progesterone avoided premature estrus.

Abstract

The objective of this study was to show the distribution of cows by days in milk (DIM) at first artificial insemination (AI) and the interval from calving to conception. The study was conducted in 47 commercial dairy herds in Enrekang Regency from May to October 2011. Of 289 animals, 143 of them or 49.5% were dairy Holstein Friesian cows with parities one to seven; mean (±SD) 2.05±1.50. The cows were classified into six groups based on DIM at first AI; within 40 d postpartum, between 41 and 85 d, 86 and 115 d, 116 and 150 d, 151 and 210 d, and 211 days or more. The cows were classified into five groups based on the interval from calving to conception; within 85 d postpartum, 86 and 115 d, 116 and 150 d, 151 and 210 d, and 211 days or more. The results of this study showed that the interval from calving to first AI was 131.6±121.8 d. The percentage of cows inseminated within 85 d after calving was only 56.1%; significantly lower (P < 0.01) than the percentage in the list of fertility management assessment standard. Likewise, cows conceived within 150 d after calving was only 32%. In conclusion, a longer average days in milk (DIM) at first AI in dairy cows was found in the present study, subsequently reduced the possibility of the cows to become pregnant in an optimum time, and reduced the reproductive performance of the herds.
