Identifikasi Sistim Produksi dan Keragaan Produktivitas Domba Ekor Gemuk di Kabupaten Brebes Propinsi Jawa-Tengah
ABSTRACT: 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.
