Abstract
This research aims to determine Bali cows’ reproductive management and performances, kept by smallholder farmers with intensive and semi-intensive production systems in South Konawe Regency. A total of 55 farmers and 110 Bali cows was interviewed and observed. The data was captured consists of farmers’ characteristics, reproductive management, and reproductive performances. An independent sample t-test analyzed the data. The farmers with intensive and semi-intensive production systems could detect the estrus well (69.57 and 59.09%) and mated by artificial insemination (AI) (70.83 and 86.11%). There was a significant difference (P <0.05) related to the first estrus age (1.98±0.82 vs. 1.92±0.18 years), the first mating age (2.84±0.23 vs. 2.77±0.34 years), service per conception with natural mating and AI (1.00±0.00 vs. 1.20±0.42 and 1.70±0.76 vs. 1.44±0.57 times). There were no significant differences in the first calving age, gestation length, postpartum estrus, postpartum mating, weaning age, calving interval, and cow reproduction index. The pre-weaning mortality and calf crops were 6.25 and 9.68%; 76.79 and 71,70%. To conclude our findings, the farmers in South Konawe Regency carry out reproductive management well. Bali cows’ reproductive performance with an intensive system is better than the semi-intensive system based on the calf crop.

Abstract
Leaves of sweet basil (Ocimum basilicum) are categorized as a tonic spice in culinary and also often used as herbs. The use of sweet basil leaves is usually dried as a spice to give a distinctive flavour to the cuisine. This study aimed to determine the effect of sweet basil leaves (Ocimum basilicum) application with different percentages on the physical and organoleptic qualities of chicken meatballs. This study used a Complete Randomized Design with 4 treatments and 5 repetitions. The treatments in this study consisted of different percentages of sweet basil leaves powder at P0: 0%, P1: 2%, P2: 4%, and P3: 6%. After chicken meatballs were cooked and stored at room temperature for 24 hours, then the measurement of physical and organoleptic qualities was carried out. The obtained results showed that the addition of sweet basil leaves had a real effect (P<0.05) on cooking loss, pH value, aroma, flavour linking, and basil flavour of chicken meatballs. However, there was no significant effect (P>0.05) on the water content. It is concluded that the application of sweet basil leaves (Ocimum basilicum) at 4% could effectively improve and retain the physical and organoleptic qualities of chicken meatballs for 24 hours.

Published: June 2021

Abstract

Garcinia atroviridis or by Indonesian name is Asam Gelugur (tamarind) is often used as a spice for cooking in Indonesia. Garcinia fruit contains minerals, vitamins, fibre, flavonoids, hydroxy citric, ascorbic, malic, tartaric, and also other ingredients that are useful for health and cause a decrease in the quality of meat. The purpose of this research was to explain the effect of Garcinia extract on water content, pH, and cooking loss values of rejected laying hens. The study used a completely randomized design (CRD) with 4 treatments and 5 replications. The treatment was given to the rejected laying hens meat that were marinated in Garcinia extract levels that are 0% (P0), 2% (P1), 4% (P2) and 6% (P3) for 15 minutes and then stored for 48 hours at room temperature 270C to 300C. Based on the analysis of variance and test results with DMRT showed that using Garcinia extract at all levels had a highly significant different (P<0.01) of the water content, pH and cooking losses of rejected laying hens meat. Garcinia atroviridis at 4% level effectively maintains the quality of meat during storage for up to 48 hours because it produces the normal water content, pH and reduces cooking loss.

Published: June 2021

Abstract
One of the genetic superiority of river buffalo can be seen from the genes controlling milk production. One of the well known genes that can control milk production in river buffalo is Signal Transducer and Activator of Transcription 1 (STAT 1). This study was conducted to identify the STAT 1 gene polymorphisms in river buffaloes in Indonesia. A total of 36 head of water buffalo including bulls (12) and calves (24) were collected Lembang Artificial Insemination Center, North Sumatra Artificial Insemination Center, BPTU-HPT Siborongborong, Deli Serdang District, and Medan District. Hair samples from each individual were collected for obtaining DNA samples. The amplification was carried out to obtain STAT1 partial sequence covering intron 9 to intron 11. This study found the G23549C and the T24011C loci polymorphism in Indonesian river buffalo for the first time. Both loci were polymorphic in both bulls and calves population. The polymoprhism information found in this study suggests that the STAT1 gene has the potential to be used as a genetic marker for buffalo milk production. Further studies are needed to prove this hypothesis.
