<p>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.</p><p>(Keywords: Pre-weaning growth, Bali cattle)</p>

The primary cause of sperm quality decline during the freeze-thaw pathway is the peroxidation hazard caused by reactive oxygen species produced by the biological molecules of sperm. Ascorbic acid (Vitamin C) and lycopene are two potent antioxidants that operate to prevent oxidation processes. This study aimed to analyse the effects of ascorbic acid and lycopene on the motility, viability, abnormality and plasma membrane integrity of post-thawed Sapudi rams. Sperm samples were obtained and pooled from six sexually mature Sapudi rams, separated into ten equal proportions and diluted with TEY extender. Semen was supplemented with 0 (C0; L0), 1 (C1; L1), 2 (C2; L2), 3 (C3; L3) and 4 (C4; L4) mg/100mL (1-4%) diluent each of ascorbic acid and lycopene, respectively. Total sperm motility, viability, abnormalities and semen membrane plasma (%) were analysed after thawing. C3 and L3 extenders resulted in higher total motility (p<0.05) compared to the other extenders, with all treatments higher than that of the control. The extender C3 (p<0.05) exhibited the highest semen quality.Finally, the current findings show that C3 and L3 can increase the quality of post-thawed Sapudi ram spermatozoa.
