Abstract

Productive and reproductive performances of 85 heads of Ettawah-cross (Peranakan Ettawah or PE) does at first breeding were studied at the Research Institute for Animal Production, Bogor . They were fed freshly-chopped King grass (Pennisetum put7xtreophoides) and corn-husk (2 :1) ad libitum and concentrate feed was given at a rate of 300 - 400 g/head/day . During the last month of the pregnancy and lactation period the amount of concentrate feed was increased to 500 - 700 g/head/day . Sixty-five does were in pre-pubertal stage and 86 .2% reached puberty at liveweights between 16 - 21 .8 kg (mean 18 .8 t 0 .4 kg) which is about 60% of mature liveweight . Oestrus without ovulation was found in 6% of the animals which has contributed on the relatively low conception rate (64 .7%) . A high pre-weaning mortality of kids born (37 .5 %) caused production inefficiency that suggests the challenge to improve management practices . Milk yield of PE does varied widely (0 .3 - 0 .8 kg/day), hence, there is a chance for improvement towards increasing milk production in Indonesia through well planned selection program. Key words: Goat, Ettawah-cross, reproduction, milk

Abstract

An evaluation was conducted of the returns to fattening cattle of small- and medium-scaleenterprises in East Java. The objective was to analyze income over feed costs (IOFC) based on locallyavailable feedstuffs to increase liveweight gain. The study was conducted during July-September 2010and January-March 2011, representing relative dry and wet season. The breeds were PO and Limousinand Simmental crossed with PO (LimPO and SimPO). Small-scale farmers owning 1-2 bulls andmedium-scale farmers fattening 10-20 bulls in one period. Fattening period was 58 and 46 days,respectively for dry and wet season. Monthly measurements included liveweight, feed intake, input andoutput prices. Mean values of growth rates and IOFC were compared using t-tests. The results indicatedthat, for small-scale operations, SimPO bulls gave a significantly higher return than either PO or LimPObulls. Likewise, LimPO gave a higher IOFC than SimPO in medium-scale operations. Small-scalefarmers achieved equal or higher IOFC for European-cross than medium-scale farmers in both seasons.This reflects that cash outlays for feed were about two-thirds that of medium-scale operations whiledaily growth rates were similar. Small-scale fattening operations using European-cross can befinancially competitive with medium-scale operations in both wet and dry seasons.
