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.

Abstract

In ruminant livestock, it is very important to pay attention to the adequacy of micro minerals and vitamins, considering that minerals and vitamins are absolute and must be present in the feed so that the health and productivity of the livestock is not disturbed. To produce quality semen, vitamin E, selenium and zinc are needed. These micronutrients play a role in the spermatogenesis process which will have an impact on the quality of spermatozoa produced by male livestock. The aim of this study was to determine the effect of supplementation of micronutrient on sperm movement pattern of Bali bull. This study was used two Bali bull aged 4-5 years with a body weight of 300-350 kg. The study was divided into two periods of treatments and each period was carried out for three weeks. In the first period (control), experimental Bali bull was fed natural grasses and concentrate (1% of body weight). Furthermore, in the second period (treatment period), the feed was similar as the first period with the addition of a mixture of minerals (Zn and Se) and vitamin E. The volume, color, pH, viscosity and movement pattern of the bull's sperm were recorded. Likewise, sperm concentration, motility, viability and abnormality were measured. Fresh semen was diluted with Andromed® accordingly before subsequent processing. Data were analyzed using paired student t-test. The results of the study showed that the macroscopic quality of fresh semen of Bali bull improved after supplementation of micronutrient. The movement pattern of spermatozoa after administration of micronutrient supplements did not have a significant effect (P>0.05). It can be concluded that micronutrient supplementation in Bali bulls can improve macroscopic evaluation, abnormality, viability, concentration and maintained spermatozoa movement patterns.

Abstract

The hematological profile and blood metabolite status are indicators of the physiological condition of livestock. This study aimed to determine the correlation between blood metabolite profiles (blood glucose and cholesterol) and sperm quality (motility and abnormality) in fresh Bali bull semen. Blood collection and semen sampling were conducted twice a week for 5 weeks. The collected blood and fresh semen were evaluated from two treatments: before and after the addition of micronutrients (including Zn, Se, and Vitamin E) in the feed. The parameters observed in this study were blood metabolite profiles (blood glucose and cholesterol levels) and sperm quality (percentage (%) motility and % abnormality of spermatozoa) before and after the addition of micronutrients. The data obtained were analyzed using simple linear regression and correlation tests. The results of this study showed that both treatments had a correlation between blood metabolite profiles and sperm quality in fresh Bali bull semen. Blood glucose levels correlated with sperm motility in fresh Bali bull semen, and good sperm motility values were obtained in all treatments before and after micronutrient administration in the feed. Cholesterol levels correlated with sperm abnormalities in fresh Bali bull semen, and all treatments before and after micronutrient addition in the feed showed abnormality values above the standard value. The blood metabolite profile (glucose and cholesterol) correlates with spermatozoa quality (motility and abnormalities) in fresh semen from Bali bull, where the addition of micronutrients in feed can increase spermatozoa motility but is not effective in suppressing the decrease in spermatozoa abnormalities.
