ABSTRAKPenelitian ini bertujuan mengkaji pengaruh berbagai faktor non-genetik terhadap bobot badan pada umur yang berbeda (lahir, 30, 60, 90 dan 120 hari) dan rataan pertambahan bobot badan (dari lahir sampai 30, 60, 90 dan 120 hari) pada kambing peranakan ettawah. Data anak kambing peranakan ettawah sebanyak 314 diambil dari Pusat Perbibitan Pedesaan Nasional di Kaligesing Purworejo Jawa-Tengah untuk dianalisa. Rataan bobot lahir (BW=3,44 kg), 30 hari (W30= 7,19 kg), 60 hari (W60= 11,05 kg), 90 hari (W90= 14,75 kg), 120 hari (W120= 18,86 kg), dan rataan pertambahan bobot badan dari lahir sampai umur 30 hari (ADG30= 125,6 g), 60 hari (ADG60= 126,97 g), 90 hari (ADG90= 125,87 g), 120 hari (ADG120= 128,78 g) dipengaruhi oleh jenis kelamin, jumlah anak sekelahiran, dan umur induk. Rataan BW, W30, W60, W90, W120, ADG30, ADG60, ADG90, dan ADG120 pada jantan lebih tinggi daripada betina. Rataan bobot lahir pada kelahiran kembar (dua dan tiga) lebih ringan Rataan bobot lahir pada kelahiran kembar (dua dan tiga) lebih ringan dibanding pada kelahiran tunggal. Rataan bobot dan pertambahan bobot badan meningkat dengan bertambahnya umur induk. Implikasi hasil penelitian ini dapat digunakan untuk evaluasi genetik dan kemampuan induk dalam rangka memperbaiki kambing Peranakan Ettawah. (at birth, 30, 60, 90, and 120 d of age), and on average daily gains (from birth to 30, 60, 90, and 120 d) of Ettawah Grade kids. Data from 314 records kids at the national village breeding centre of Kaligesing Purworejo Central Java province were analyzed. Results showed that average live weights at birth (BW= 3.44 kg), 30 d of age (W30= 7.19 kg), 60 d of age (W60= 11.05 kg), 90 d of age (W90= 14.75 kg), 120 d of age (W120= 18.86 kg), and average daily gain from birth until 30 d of age (ADG30= 125.6 g), 60 d of age (ADG60= 126.97 g), 90 d of age (ADG90= 125.87 g), 120 d of age (ADG120= 128.78 g) were influenced by sex, litter size, and age of dams. Means of BW, W30, W60, W90, W120, ADG30, ADG60, ADG90, and ADG120 of males were higher than females. Multiple (twin and triplets) born kids were lighter than single. Mean of body weight and average daily gain increased with the dam's age. The implication of these findings should be accounted in genetic evaluations and also should consider maternal ability for the improvement of Ettawah Grade.

Characterization of local goat of kejobong at local government of purbalingga, central javaABSTRACT. The purposes of this study were to identify the quantitative morphogenitical characteristics (external body dimensions) and qualitative characteristics (coat-colour), the population size, its distribution and diversity of morphogenitical characteristics, the population status in term of conservation, and to find out the model of conservation. The target of this study were goat-husbandry of local goat at Kejobong (13 villages) Local Government of Purbalingga, Central Java, Purbalingga Regency. Livestock On-Farm Trials (LOFT) by simple random sampling was implemented in this study. Sample sizes were determinate by Nomogram Harry King, and were involved of 931 head of local goat of Kejobong. Descriptive (qualitative and quantitative) analyses, variance analyses by General Linear Model (GLM) procedure of SPSS, analysis of the population status according to the Global Data Bank for Farm Animal Genetic Resources for Domestic Animal Diversity of FAO were applied.This study revealed that: (1) based on the size of external body dimensions, the Kejobong local goat appears the termediate between Kacang and Peranakan Etawah goats; (2) ) Based on the quantitative and qualitative characteristics, the Kejobong local goat assumed as a crossbreed-goat resulted from crossing between Kacang and Peranakan Etawah breeds. Dominant black and total black coat colour were predominants 74.45 and 56.49 percent among their population, respectively; (3) The Kejobong local goats were founded in all regions (13 villages) with the total populations about 15.317 heads. There was highly diversity in term of the characteristic of external body dimensions. This finding force to conduct the in-breed selection in order to improve their productivity; (4) Based on the Global Data Bank for Farm Animal Genetic Resources, the population status of local goat at Kecamatan Subdistric (15.317 heads) and the total population of black coat (8.623 heads) were classified into Not at Risk category. Board of Agriculture National Research Council (1993) classify that the population status into rare if the size of population ranges from 5.000 until 10.000 heads, it is imply that the total population of black coat goat (8.623 heads) include in rare category; (5) The policy of livestock conservation consists of the in-situ and ex-situ methods. In the level of implementation of the sustainability conservation, there were some aspects could be take into account such as agreement between government (political will and coordination), community (group farmer, empowering capital and marketing), and universities.

Reproductive performance is one of the main determinants of productivity of the sheep. This applies to the breeding of animal for meat production. High reproduction rates are essential for profit in meat sheep production and determined by the number of progeny delivered in a given period of time. The level of reproductive performance is dependent on the interaction of genetic and environmental factors. The evaluation of reproductive performance of a local and adapted breed of sheep such as Fat Tailed Sheep can provide important information to understand its productive potential under local production system. The study was designed to identify characteristic of production system and to find out the level productivity of Fat Tailed Sheep in Brebes areas of Central Java. Livestock On-Farm Trials (LOFT) using multistage sampling was implemented in this study. Descriptive and variance analysis using procedure of General Linear Model (GLM) was applied in this study. This study revealed that (1) In general, production system in Brebes is based on integration scheme of crop livestock in the form of traditional smallholders. In low land area, mostly extensive and tethering model were implemented. Intensive and semi intensive model was found in landless area. (2) Average litter size at birth was 1.54 head and dominated by double litter, followed by single and triplets (46.8, 47.88 and 4.29%). The highest preweaning lamb mortality was 15% with the average 8.9%. Ewe productivity ranges from 1.76-5.24 with average of 2.14 lamb/ewe/year. Least squares analysis of variance reveals that ewe reproduction rate was significantly affected by type of birth.

The objectives of this study was to determine the performance of beef cattle farm under improved production systems of farmer group in the rural areas. Data were collected from 20 beef cattle farmer groups located in Cilacap, Banyumas, Banjarnegara and Kebumen regencies. Intervension factors such as improved production system including aspecs of institutional, banking access, diversification of business, trading, and development programs. Regular reporting, interviews, field observations, and forum group discussion were implemented. Descriptive analysis was applied in this study. Variables focused on livestock production systems improvement, type and performance of development progam, social resource potential and group dynamics, productivity levels, and also proposed program and recommendations of action programs. This study revealed that 10% of beef cattle farmer group implementing fattening cattle, and mostly (90%) applying combination of cow-calf operation and fattening. All of the beef cattle farmer group (100%) had a high score of social resources potential, while the group dynamics tend to stable (60%) and increased (40%). Mean of reproduction performance were 2.4 (S/C), 13.7 month (calving interval), and 76.5% (pregnancy rate). In general, BCS ranging from 4 to7 with the highest score of 6 (45%) and followed by 7 (40%). Follow-up activities for recommendation of the action program could be the Beef Cattle Cluster Development of Farmer Group Based in the Rural Areas.

The purposes of this study was to describe the developoment type and productivity of Beef Cattle at the Community Development Partnership Program. Purposive samping method was implemented by survey at the beef cattle farmers who are member of the Community Development Partnership Program located at Banyumas and Cilacap regencies of Central-Java province. Qualitative and quantitative descriptive statistics were applied in this study. It is found  that fattening and growing type (in Banyumas) and fattening type (Cilacap) was practiced. Intensive fattening of Simental, Limosine, Charalois Cross cattle by 45-96 days of periods found in Cilacap, and extended fattening of Madura, Bali and Sumba Ongole Cross Cattle for Idul Qurban purposes found in Banyumas.
