Abstract

Two experiments were carried out to study the use of rice straw as the sole source of roughage in ration for cattle fattening. In each experiment 16 heads of young bulls, Frisian Holstein (FH), and Australian Commercial Cross (ACC). were arranged in completely randomized design with 4 different roughages as treatment criteria: (i) elephant grass as control, (ii) unprocessed rice straw, (iii) urea treated rice straw, (iv) CaO traated rice straw. No significant difference in weight gain among treatments in both experiments exist. In the firrst experiment the average daily gain (ADG) for treatment 1, 2, 3 and 4 was respectivelly 0.75, 0.78, 0.89, and 0.78 kg, while in the second experiment the ADG was respectively 0.51, 0.48, 0.71, and 0.62 kg per head per day. On the average the FH bulls performed superior gain of 0.80 kg/head/day while the ACC is moderate (0.58 kg/had/day). In the first experiment no significant difference in dry matter consumption among treatments obtained. In the second experiment the dry matter consumption of elephant grass was lower compared to strawmix. FH bulls show higher consumption of dry matter (3.1% of live weight), while the value of ACC bulls is only 2.5% live weight.  Feed efficiency is not statistically different among treatment in both experiments, namely 9.1, 8.0, 7.4 and 8.4 kg dry matter/kg ADG in the first experiment, and 13.9, 19.6, 11.8, and 14.8 dry matter/kg ADG in the second experiment. FH bulls show higher efficiency of 8.2% while ACC bulls is only 15.0%.

Abstract

Two groups of chickens were surgically bursectomized at 3 days of age. One week after the operation the experimental chickens were injected i.m. with ND vaccine starin La Sota. The 2nd injection was given 4 weeks after the ist injection. All injected chickens showewd an increase in HI-serum antibody titer. The response to the 2nd injection was higher than the ist The bursectomized animals showed lower HI antibody titer than the non busectomized after the ist injection, but a reverse response was observed after after the 2nd injection. Lymphocyte count showed a similar pattern as the HI antibody titer. Better responses were observed in the Indonesia native chicken compared to the white Leghorn. The increase of the serum globulin levels in both groups after the ist injection, the beta and gamma serum globulin levels in almost all injected chickens were elevated, except fot the bursectomized. White Leghorns, where the gamma globulin fraction was not increases.

Abstract

The sheep seems to be a suitable and socio-economically acceptable animal for livestock production in Indonesia due its small and size and certain physiological characteristics of sheep whith say offer adventages for rearing over larger ruminants. The sheep population is however declining up to present. One way for improvement of sheep production has been attempted through crossbooring with imported breeds.A research project on certain aspects of sheep reproduction is discussed with omphasis on plasma reproduction hormonal levels, and with emphasis on plasma reproduction hormonal levels, and with the ultimate objective to rapidly increase the presently declining sheep population.

Abstract

An experiment was conducted to evaluate substitution of native grass and rice bran eith palm press fiber (PPF) and dried palm oil sludge (POS) in nine growing males dairy cattle. The animal had a mean of liveweight of 190 ± 11.2 kg. Levels of substitution were 0, 50, and 100% or 0, 15, and 30% of ration dry matter.Inclusion of PPF and POS in ration had no effect on daily liveweight gain (1.270 ± 0.2 kg). Analysis of empty body composition using the urea space technique revealed that the liveweight gain was associated with deposition of protein and fat. PPF had a low palatability and reduced total dry matter intake when the inclusion was higher than 7% of ration dry matter. However, the PPF was fermentable and volatile fatty acids (VFA) concentration in the rumen increased linearly as PPF level increased in the ration (VFA = 75 ± 0.53 PPF; P<0.05). The intake of the digested organic matter was 2.63, 2.68, and 1.97 kg and that of digestible energy was 19.3, 19.5 and 15.5 Mcal for ration caontaining 0, 15, 30% of PPF, respectively.It was concluded that the POS was an excellent substitute for rice bran, but PPF as a grass substitute should be limited up to 23% of total grass dry matter or 7% of ration dry matter.
