Abstract

Balai Pembibitan Ternak Unggul is a breeding center established by the Government of Indonesia (GOI) to perform preservation, breeding, breeding stock production and development, and also the distribution of breeding stock of Excellent Bali cattle at national level. In the production of excellent breeding stock through the performance test and progeny test. Pre-weaning growth is one of the important indicators for the population growth. The study was aimed to identify the pre-weaning calf growth rate of Bali cattle in 2010-2011, born from performance-test-passing-dams that were collectively reared with progeny-test-passing sires. Materials used were 84 pre-weaning Bali calves. This was a survey method-based descriptive analysis research. The results showed that in terms of the performance of pre-weaning growth, the birth weights of male and female calves were 18.37±1.65 kg and 18.27±1.29 kg, respectively. The weaning weights of male and female calves were 93.53±21.00 kg and 87.66±12.04 kg, respectively, with weaning time of 205 days. The average of daily weight gain (ADG) were 0.37±0.10 kg/head/day (male) and 0,34±0,06 kg/head/day (female). It was concluded that the pre-weaning calf growth rate of Bali cattle at the BPTU Bali in 2010-2011 were moderately high since they were born from the dams and the sires passing the performance test and progeny test.(Keywords: Pre-weaning growth, Bali cattle)

Abstract

This study aimed to study the blood plasma minerals of  thin-tailed weaning ram prior to administration of Sargassum sp. as a source of minerals. Research materials and methods. The use of Sargassum sp. seaweed flour. sun-drying on 16 weaned thin tailed rams, aged 5-6 months with a bodyweight of ±11.8 kg for 3 months, using a 4x4 completely randomized design (CRD) with four treatments, namely T1 = forage + concentrate + 0% minerals of concentrate, T2 = Forage + concentrate + cow booster minerals 0.38% of concentrate, T3 = forage + concentrate + Sargassum sp.5% of concentrate, T4 = forage + concentrate + Sargassum sp.10% of concentrate. The observed research variables were the consumption of macro minerals (Ca, Mg, K, and Na and micro minerals Cu, Fe, and Zn) and  balance of macro minerals Ca, Mg, K. and Na and micro minerals (Cu, Fe, and Zn blood plasma before and after treatment with seaweed Sargassum sp. The results showed that the treatment had a significant effect (P<0.05) on mineral Ca consumption, Mg, K, Na, Cu, Fe, and Zn. Blood plasma minerals before treatment did not differ on Mg, Na, Cu, Fe, Zn, but had a significant effect (P<0.05) on Ca and K. The treatment had a significant effect (P<0.05) on minerals Mg, Cu, and Fe in blood plasma, but did not affect Ca, K, Na, Zn. Based on the results obtained, the use of Sargassum sp. 10% of the total concentrate with sun drying can increase the consumption of macro and micro minerals as well as increase the minerals Mg, Cu, and Fe in the blood plasma of weaning rams.
