This research aim to know: 1. Performance of Simmental crossbred and Ongole crossbred cow in pregnant period seven months to pregnant again in ranch of people. 2. Performance of calves before weaning from Simmental crossbred and Ongole crossbred dams. 3. Feed intake on prepartum and postpartum period. This research was carried out in Bambanglipuro district, Bantul sub-province form June 2003 to June 2004 with 18 Simmental crossbred and 18 Ongole crossbred cows in pregnant seven months condition. The variables observed were change of cows body weight during research, birth weight and growth of calf, postpartum estrus, service per conception (S/C), conception rate (CR), pregnancy rate, calving interval, quality and quantity feed intake. The data on gain weight of the cows, body weight at parturition, birth weight of calf, postpartum estrus and calving interval were analyzed using T test while S/C and CR were analyzed using Chi-Square. The result of the research showed that gain weight both of breed cows have increase until before parturition and then decreased. Simmental crossbred body weight was higher (P<0,01) than Ongole crossbred (463,70 ± 47,29 kg vs. 349,90 ± 63,34 kg) but changes of body weight daily before parturition did not differ significantly. Birth weight calf of Simmental crossbred was higher (P<0,01) than Ongole crossbred (37,47 ± 5,03 kg vs32,17 ± 4,08 kg), average daily gain calf Simmental crossbred was higher (P<0,01) than Ongole crossbred (1,04 ± 0,30 kg/head/day vs 0,72 ± 0,15 kg/head/day). Length gestation, postpartum estrus, calving interval, S/C, CR did not differ significantly. Dry matter and crude protein intake before parturition did not differ significantly, dry matter intake after parturition, Simmental crossbred have higher (P<0,01) than Ongole crossbred (10,97 ± 2,52 kg vs. 8,44 ± 2,05 kg). The conclusion of this research was that performance of Simmental crossbred was better than Ongole crossbred in the case of body weight and performance of calf

ABSTRACT
The study was carried out on plastic house in Farm belong to the Laboratory of Forage and Pasture of the Animal Sciences Faculty, University Gadjah Mada, Yogyakarta. This research was intended to get the data about the effects of harvesting time and inoculant addition on peanut productivity. Twenty four polybags (plastic bags) were used and each containing 15 kg of soil. The soiltype was of kind of Alfisol (Mediteran) from Gunung Kidul district. Experimental design was factorial, namely 2 x 2 x 2 treatment factors with 3 replication arranged in a complelety randomized design (CRD). The three treatment factors were: Harvesting time factor (UP) consisted of UP1=harvested at 80 days and UP2=harvested at 90 days of age; Soil factor (T) consisted of To=not sterilizated and Ts=sterilized, and Legin factor (L) consisted of Lo=not inoculated and L1= inoculated. The results of the study showed that there were highly significant (P < 0.01) effect of all the treatment factors on dry matter (DM) production (0.59 ton vs 0.69 ton/ha), CF (28.25% vs 24.59%), ash (10.11% vs 9.48%) and NFE (41.21% vs 46.05%). Soil factor (T) was effected highly significant (P < 0.01) on dry matter (DM) production (0.72 ton vs 0.56 ton/ha),CP (16.01% vs 18.07%) and ash (9.44% vs 10.15%). Legin factor (L) was also effected highly significant (P < 0.01) on IVDMD (59.90% vs 62.77%) and IVOMD (58.86% vs 62.65%) but effected to ash only (P < 0.05) (9.55% vs 10.03%). It also formal that interaction between three factors (UPxTxL) affected DM production (0.47 ton/ha on UP1TsL1 to 0.79 ton/ha on UP2ToLo), and CP (14.81% on UP1ToLo to 18.58% on UP1TsL1). EE, ash, NFE, IVDMD and IVOMD were also depended on interaction between two factors (UP x T), (UP x L) and (T x L). It can be concluded that nutritive value of peanut forage decreased, while forage DM production of biomassa above the ground increased as the harvesting age increases from 80 to 90 days. The highest peanut productivity was obtained when planting was carried out with inoculation on unsterilized soil.
