Ciptadi G, Ihsan MN, Nurgiartiningsih VMA, Ardyah IP, Mudawamah M. 2017. Short Communication: The normal karyotyping result of Indonesian native breed bull qualified for artificial insemination. Biodiversitas 18: 1462-1467. Bali and Madura cattle are important native breed in Indonesia, both descendants of wild banteng (Bos javanicus). These breeds are categorized as a small type beef cattle, and are indigenous, well adapted and, have high resistance to diseases. The aims of this research were to analyze dendrograms of these breed and karyotype breeding bull selected for Artificial Insemination (AI). The result showed that the 2n diploid number of chromosome of all cattle was 60 and they were considered normal, based on the number and structure of chromosomes. Fiftyeight acrocentric autosomes and 2 sex chromosome were observed, including a submetacentric X-large chromosome submetacentric and a small Y chromosome. Dendrogram analysis showed that Bali and Madura cattle were closely related and derived more from their ancestor wild banteng than from Java cattle. It is recommended to perform a chromosomal investigation of breeding bulls especially those used for freezing semen production and AI implementation.

A crucial trait of a high economic value of goats is calving to more than one kid (prolificacy potency). The high prolificacy potency (> 1 kid) has a higher income compared to single kids. This study described the potential of Indonesian Local Etawah Goat (ILEG) for prolific trait and the morphometric of body and breeding values in various environments as a basis for selection.  It involved smallholder farmers who breed ILEG does from 14 villages in East Java. The research was conducted on a field survey to obtain primary data about the phenotypic superior ILEG goats based on the status of the prolific trait. The study used 520 does with 1347 prolific records obtained. The results showed that the prolificacy values ranged from 2.12-1.42 heads/calving (medium to high category). The variation of prolificacy was 0.53, and the breeding values of the prolificacy trait were 1.48-1.74. The average of body morphometrics was varied with the following details.  Chest circumference was 81.06 + 4.63 cm, body length was 76.64 + 4.33 cm, shoulder height was 75.34 + 5.83 cm and ear length were 27.44 + 3.02 cm.  This study concluded that the prolific rate was medium to high category.  The prolific variation was higher than body morphometry variation, and the prolificacy EBVs of breeding villages divided into four unique pattern boxplots. The prolific trait could be the basis for new considerations in the ILEG breeding program, either through selection or mating.

The characteristic of local quality goat meat in every country had been researched including in Indonesia. This research aimed to determine the properties of physical and chemical of Kacang goat meat as the character of goat meat and it could be a reference for comparison of the various quality goat meat in the world. Materials and methods: The study was conducted in Lamongan Regency, East Java, Indonesia on 40 male and female Kacang goat meat samples and at the loin and round section. The sampling was done by purposive random sampling methods. The research method was a laboratory exploratory. The observed variables were pH, Water Holding Capacity (WHC), cooking loss, shear force, Proximate and functional group characteristics with FTIR. The results: The range of physicochemical properties of Kacang goat meat covers: pH = 6.02 ± 0.09 to 6.13 ± 0.13, WHC = 35.22 ± 0.83 - 35.41 ± 0.88 %, Cooking Loss = 33.24 ± 0.85 - 35.40 ± 1.51 %, shear force = 5.50 ± 0.07 - 5.59 ± 0.1 kg/cm2. The proximate value of Kacang goat meat were: Water content = 77.20 ± 0.19 - 77.35 ± 0.54 %, Protein = 18.60 ± 0.35 - 20.08 ± 0.19 %, Fat = 4.50 ± 0.41 - 4.69 ± 0.20 %, Energy = 749.71 ± 9.43 Kcal/kg - 762.18 ± 12.18 Kcal/kg, Ash = 1.81 ± 0.16 - 1.90 ± 0.04 %. FTIR spectroscopy of Kacang goat meat showed wavelengths at peak absorption ranging from 700.16 to 2,956.87 cm–1. Conclusion: There was a variated of physicochemical and characteristics of the functional group Kacang goat meat in Indonesia, especially based on sex and section of meat. GRAPHICAL ABSTRACT

This study was conducted to estimate the repeatability and MPPA values of Sapudi ewe based on birth weight and weaning weight. Samples used 93 Sapudi lambs from 26 ewes that lambed three times, and the observed variables were lambing weight and weaning weight. Collected data were analyzed quantitatively. Estimating repeatability by analyzing the variance of the relationship between sibling and the parental rank was based on the relative MPPA formula..  The results showed that the average lambing and weaning weights were 2.789±0.206 kg and 10.058±1.470 kg. The repeatability of lambing and weaning weight were 0.108±0.119, and 0.565±0.104 belonged to the low and high categories. The average MPPA of lambing and weaning weight were 0.001 and 0.087. MPPA values of lambing and weaning weight range from -0.087 to 0.075 and -1.721 to 2.713. The highest ranking of the Sapudi ewe in lambing and weaning weight is ear tag 103 and ear tag 27 with MPPA 0.075 and 2.713. It can be concluded that there were 11 ewes with MPPA lambing and weaning weight above the average MPPA population that should be maintained in the population.

The improvement of the quality of polluted irrigation water through a phytoremediation process in a hydroponic batch culture system AIP Conference Proceedings 1908, 030003 (2017) Corresponding author: ciptadi@ub.ac.idAbstract. The aims of this research are to study the potential source of mature (M-II) oocytes of domestic animals using follicles isolated from prepubertal and over mature aged Indonesian local goats, resulting from an in vitro growth (IVG) method. This method of IVG could provide a new source of M-II oocytes for embryo production. In Indonesia, a very limited number of a good quality oocytes are available for research purposes, as there is a limited number of reproductive females slaughtered, which is dominated by prepubertal and old mature aged animals. IVG culture systems could be improved as an alternative method to provide a new source of a good quality oocytes for in vitro maturation of M-II oocytes. From a number of prepubertal and mature aged goats slaughtered in a local abattoir, the small oocytes in the preantral follicles were cultured in vitro to normal oocyte growth. The methods used in this research are experimental. Follicles were isolated, cultured in vitro for 14 days individually using a sticky medium containing 4% (w/v) polyvinylpyrrolidone in TCM 199 10% Fetal Bovine Serum supplemented with Follicle Stimulating Hormone, which was then evaluated for their follicle development and oocyte quality. The research results showed that a minimum follicle size and oocyte diameter is needed (>100 um) for early evaluation of maturation to be achieved, meanwhile oocytes recovered from IVG after being cultured in vitro for maturation resulted in a very low rate of maturation. However, in the future, IVG of the preantral follicles of Indonesian local goat could be considered as an alternative source of oocytes for both research purposes and embryo production in vitro.
