Abstract

Aims of this research was to determine the effect of distance and the duration of straw count above liquid nitrogen to the Quality of Frozen Simental Cattle. This study used a sample derived from simmental cattle from BBIB singosari as much as 48 straw divided into 8 treatments. P1(0,5cm 15 sec), P2(0,5cm 30 sec), P3( 0,5cm 45 sec), P4(0,5cm 60 sec), P5(1,5cm 15 sec), P6(1,5cm 30 sec), P7(1,5cm 45 sec), P8(1,5cm 60 sec) and repeated as much as 6 times then observed for motility and viability of post thawing spermatozoa. The data obtained were analyzed using SPSS 16.0. The data obtained were analyzed using SPSS 16.0. The results showed that the duration of straw count and the position of straw from liquid nitrogen  not significant (P>0,05) on post thawing motility. The position of straw from liquid nitrogen not signifant (P>0,05) on post thawing viability. The conclusion of this research showed that 0,5 cm 15 sec give the higher post thawing motility.

Abstract

The aim of this research is to know the effect of pomegranate (Punicagranatum L.) on the improvement of spermatozoa quality that is increase of percentage of capacitation and acrosome reaction in white rat (Rattusnorvegicus). This research used 20 healthy white rat (Rattusnorvegicus) with average age 2-3 months old, 200-300 g. Research design using completely randomized design (CRD) with four treatments and 5 replications. Rats were randomly divided into 4 treatment groups. Rat in the negative control group not treated just kept alone, solvent control group were given CMC Na 0,5% and is exposed to heat, the treatment groups 1, 2, and 3 induced pomegranate extract standardized to 40% ellagic acid at a dose of 75mg / kg, 150mg / kg and 300mg /kg perorally with doses 1 ml/rat/day gastric for along 14 days and exposed to heat. Data were analyzed using One Way Analysis of Variant (ANOVA) followed by Duncan (p<0,05). The result showed that there was significant effect from therapy on the quality of rats spermatozoa especially to capacitation and acrosome reaction. The treatment from treatment 2 group showed the best result in maintaining the quality of rats spermatozoa with 27.6± 3.04 values for capacitation and 6,80 ± 1,30 for acrosome reactions. Extract of pomegranate (Punicagranatum L.) standardized to 40% ellagic acid has a significant change in improve the quality of spermatozoa, namely an increase in the percentage of capacitation and acrosome reactions in white rats (Rattusnorvegicus) exposed to heat.

Abstract

Ovarian hypofunction is a condition in which the follicles in the ovary can not develop due to lack of feed. It can affect the pituitary anterior, so the production of FSH and LH was low. GnRH can stimulate the pituitary anterior to produced FSH and LH. This study aimed to prove that GnRH injection in dairy cows with ovarian hypofunction can initiate estrus, followed by pregnancy. This study used 12 dairy cows with BCS ≥ 2.75, with anestrus due to ovarian hypofunction. All dairy cows were divided into two treatment groups, P1 injected with GnRH at a dose of 100 µg intramuscularly and P2 injected with GnRH at a dose of 300 µg intramuscularly. The results were analyzed using an independent t-test and Chi-Square test. The result showed that estrus rate of P1 and P2 were both 100%, meanwhile onset of estrus of P2 (53.83 ± 8.1 h) was shorter p <0.05) than P1 (74.17 ± 4.7 h). Both of P1 and P2 showed 100% pregnancy rate. It could be concluded that GnRH injection could initiate 100% estrus, and followed by 100% pregnancy in dairy cows with ovarian hypofunction.
