The purpose of this study was to compare the productivity of Fat-Tailed Sheep in single and twin lambing. The research method was a field study based on data recording of ewes that gave lambing three times or more. The variables observed were livestock productivity seen from the interval between giving birth and the reproduction rate of livestock. Data analysis used unpaired t-test with excel program. The results showed that twins had a very significantly higher reproductive rate (P < 0.01) and no significant difference between lambing intervals (P > 0.05) compared to single lambing ewes. This study concluded that the productivity of Fat-Tailed sheep was 88.19 % higher ewes of twin lambing than that of single lambing ewes. One of the criteria for choosing a ewe is the potential for twin lambing.

Keywords: Reproductive Rate, Calving Interval, Local Sheep.

The study aimed to determine the hip size of Indonesian Local Ettawah Goats (Peranakan Ettawah or PE) from various parity as a selection criterion for candidate goats that could be kidding without dystocia. This research method was a case study with purposive sampling that chose healthy reproductive goats marked by normal category relation with the duration of pregnancy, the age of first pregnancy, and the kidding process. Variable observed was hip length and width, and data analysis used descriptive analysis through mean and variance as well as one-way variance analysis. Hip measurement of Indonesian Local Ettawah Goats from 1st to fifth parity showed the average hip-length ranged from 82-85.67 cm and hip height varied between 19.60-21.33 cm. The variance analysis showed that the types of parity had a very significant difference (P < 0.01) on the height hips but had significant difference (P < 0.05) on the width-hips, with the variance of hip height and width, ranged 0.33-5.90 and 0.33-1.00. Hip height and width increased as high parity (1st until 3rd), while 4th and 5th parity were relatively constant in hip size. Determination coefficients between parity and hip height and width were 35,00 % and 36,30 %. This study concluded that the variance of hip width was smaller (more consistent) than the hip height of Indonesian Local Ettawah Goats. One of the basic selection criteria for Indonesian Local Ettawah doe candidates was hip-width with 19,60 cm or more.

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.

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 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.
