ABSTRAK: Indonesia memiliki beberapa jenis domba lokal, di antaranya domba Sapudi. Dalam peningkatan produksi dan populasi domba, perlu diperhatikan sistem reproduksi. Metabolisme dan fisiologi domba bunting akan mengalami perubahan yang menyebabkan komponen darah jugaberubah. Sampel penelitian, yaitu 20 ekor induk domba Sapudi yang berasal dari UPT. Pembibitan Ternak dan Hijauan Makanan Ternak Jember. Induk domba dibagi menjadi 5 kelompok sesuai fase reproduksinya, yaitu induk tidak bunting, kebuntingan awal, pertengahan bunting, kebuntingan akhir, dan induk laktasi. Variabel penelitian adalah komponen darah yang meliputi eritrosit, leukosit, hemoglobin, dan hematokrit. Metode penelitian, yaitu deskriptif kuantitatif yang
dianalisa menggunakan ragam satu arah
, dan jika berbeda nyata dilanjutkan uji Duncan. Hasil penelitian ini terdapat perbedaan signifikan (p<0,05) pada hemoglobin, sedangkan pada eritrosit, leukosit, dan hematokrit tidak terdapat perbedaan signifikan (p>0,05).

ABSTRACT: Indonesia has several types of local sheep, including Sapudi sheep. In increasing sheep production and population, it is necessary to pay attention to the reproductive system. The metabolism and physiology of pregnant sheep will experience changes which cause blood components to also change. The research sample was 20 Sapudi ewes from UPT. Livestock Breeding and Forage in Jember. Mother sheep were divided into 5 groups according to their reproductive phase, namely nonpregnant mothers, early pregnancy, midpregnancy, late pregnancy, and lactating mothers. The research variables are blood components which include erythrocytes, leukocytes, hemoglobin and hematocrit. The research method is quantitative descriptive which is analyzed using oneway variance, and if it is significantly different, the Duncan test is continued. The results of this study showed significant differences (p<0.05) in hemoglobin, while there were no significant differences in erythrocytes, leukocytes and hematocrit (p>0.05). The average hemoglobin value in the five reproductive phases is between 7.6510.50 g/dL, erythrocytes 5.786.95 106/mm3, leukocytes 8.0513.71 106/μL, and hematocrit 24.35 29.70%.

Abstract

The purpose of this study was to describe the phenotypic profile of body weight at one year of male and female came from fraternal twins in Indonesian Local Ettawah Goat (ILEG) or PE Goat. This research method was a case study with data retrieval using purposive sampling with the criteria of male and female fraternal twins. The variables observed were the average and variance of body weight in fraternal twin goats at one year. Data analysed descriptive and unpaired t-test with excel program. The results showed that male goats’ body weight at one year of age was significantly (P < 0.01) higher than that of female goats at fraternal twins. At one year of age, the body weight variance in male goats was higher than that of female goats at fraternal twins. The conclusion was that the phenotype profile of male ILEG goats was more varied, seen from the average and diversity of body weight, which was 15.37% and 52.24% higher than females. This research implies that feeding male goats should be based on body weight, not on age, to increase their potential optimally.

ABSTRACT

This research aimed to estimate the repeatability and MPPA values of Sapudi ewes based on the lamb’s daily gain from birth to pre-weaning and weaning. Using recorded data in a pedigree of lamb, 53 data with half-sib relationship came from 14 ewes which included the record of body weight gain of Sapudi lambs from birth to pre-weaning and weaning. The data were analyzed by descriptive method with a quantitative approach. The study showed that the average daily gain of pre-weaning and weaning was 007 kg/day. The repeatability value of pre-weaning and weaning daily gain was 0.636 in the high category and 0.377 in the medium category. The MPPA daily gain values for pre-weaning and weaning ranged from -0.032 to 0.018 and -0.016 to 0.009. The research concluded that the Sapudi sheep ewes based on the MPPA daily gain pre-weaning were six heads with four rankings, while the daily weight gain weaning was ten heads with ranking of five. The highest rank of Sapudi ewes in pre-weaning and weaning daily gain was ear tag 094 with MPPA values of 0.018 and 0.009. It is recommended that further research can be conducted to estimate the repeatability value of quantitative periodically as the basis for the selection and culling of livestock.

ABSTRACT

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.

ABSTRACT

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 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.
