Abstract

The production performance of Holstein-Friesian cows in West Java was evaluated in two areas, Cisarua district (Bogor) and Tanjungsari district (Sumedang). In Cisarua the evaluation was made on 175 cows with different stage of lactation (2 - 11 months). Feed offered, both forage and concentrate, milk production and chess girth were measured from each animal for 24 h only. Date of calving, date of service and stage of pregnancy were recorded by interviewing the farmers . In Tanjungsari the study was conducted on 102 postpartum cows . Milk production and chess girth were measured at the beginning of the study and then once a month (morning and afternoon milking) for 3 months. Milk production was 3,700 1 and 3,400 1 per lactation with declining rate of 0 .03 and 0 .05 1/d for Cisarua and Tanjungsari area respectively. The ratio of concentrate : forage consumption was 1 and 1 .4 in Cisarua and in Tanjungsari respectively, and the ratio was reduced as milk production declined . The efficiency of conversion of feed ME to milk yield was approximately the same (0.12 1/MJ) in both location . The proportion of cows lost weight in Cisarua during the first three months was lower (46 %) as compared to that in Sumedang (77 %). Approximately 68 % of the population have conception rate (CR) > 50 % , the remaining should be culled, 24 % have low CR and 8 % have days open > 150 days . From 61 cows observed, 71 % and 21% have a projected calving interval of 12 months and 13 - 14 months respectively . It can be concluded that milk production and reproduction efficiency of Holsteincows in West Java are considered low.   Key words: Holstein-Friesian cow, reproduction efficiency, milk production

Abstract

The objective of the research was to evaluate the relative superiority of Garut lamb and its crosses with St. Croix and Moulton Charollais. The research was conducted at Animal Research Station, Indonesian Research Institute for Animal Production, Bogor, Indonesia. The data used for this paper was collected from 1995 to 2002. The results revealed that individual lamb weight at birth, at weaning, preweaning daily gain, at 6, 9 and 12 months of age of the composite sheep (HG = 50% St. Croix : 50% Garut, MG = 50% M. Charollais : 50% Garut, MHG (MG X HG) dan HMG (HG X MG) = 25% St. Croix : 25% M. Charollais : 50% Garut) were higher than Garut sheep. The relative superiority were 6.7-13.1% for lamb weight at birth, 6.6- 15.6% for lamb weight at weaning, 3.2-20.8% for preweaning daily gain dan 6.2-17.9% for lamb weight at 9 month of age, respectively. The superiority of composite sheep were obtained in good and limited feed condition. Lamb growth parameters were also affected by feed condition, parity, sex, and rearing type.   Key words: Garut, St. Croix, M. Charollais sheep, relative superiority

Abstract

The objectives of this experiment was to evaluate the effect of drought stress and defoliation interval on shoot and root morphologic characteristic of Indigofera zollingeriana. The experiment was arranged in a completely randomized design with two factors and four replications. The first factor consisted of 3 level of drought stress i.e: 100% field capacity (FC) (control), 50% FC, and 25% FC. The second factor comprised of 3 defoliation interval were interval defoliations of 60, 90 and 120 days. The observed variables were shoot, root dry weight, root/shoot ratio and root length. Data were analyzed by ANOVA and the differences between treatments were tested by LSD. The results shows that there were interactions (P < 0,05) between drought stress and defoliations interval on shoot dry weight, while root dry weight, root/shoot ratio, and root length was not. Drought treatment significantly (P < 0,05) decreased shoot, root dry weight, but increase of root/shoot ratio and root length. Defoliation interval significantly affected (P < 0,05) on shoot dry weight, but not on root dry weight, root/shoot ratio, and root length. Key Words: Indigofera zollingeriana, Drought Stress, Defoliation Interval, Shoot And Root Morphology
