Abstract

The research is experiment in laboratory with using semen from 3 Priangan rams. The experiment use completely Randomized Design (CRD) of 4 x 4 Faktorial with three Priangan rams as replications. The treatment are equilibration time as first faktor with level 1 hour, 2 hours, 3 hours, 4 hours, and freezing time as second faktor with level 4 minutes, 8 minutes, 12 minutes, and 16 minutes.The variable observed is sperm motility, sperm abnormality, sperm membrane intact and sperm macrodome intact after thawing. Data was analysis by Analysis of Variance and further analysis by Duncan’s Multiple Range Test (DMRT).The result of experiment show that treatment between 3 hours equilibration and 12 minutes freezing time are the best significantly influence (P 0>01) with significantly (P >0,05) with significantly interaction between two factors on sperm motility, sperm membrane intact and sperm macrodome intact after thawing but there is no interaction(P<0,05) for sperm abnormality after thawing.Keywords: Equilibration, freezing, frozen semen.

Abstract

This aim of research was to know the effect of probiotics for body weight of broiler. Thirty six Daily Old Chick of broiler, strain Arbor acress, male sex were divided to become 2 group: I ( given standard food) and II ( given standard food + probiotics) with 18 chicken of each group. Probiotics were given at the age of 8 days by sprayed in food with the dose 2 ml / 250 ml water / 1 kg food. The body weight was observed for all group at the age of 8, 15, 22, and 39 days. The data of body weight were analyzed with Split plot method.The result showed that the body weight increased of group I and II was not significantly difference (P > 0,05), period I and III, II and III was significantly difference (P < 0,05). The conclusion was probiotics does not effective for body weight.Keywords: probiotic, body weight
