Abstract

The purpose of this study was to determine the effect of storage time for fresh semen on media ColdBox on the motility, viability of spermatozoa and semen pH of native chickens. This research was conducted in October 2020 at the Laboratory of the Faculty of Agriculture, University of Timor Kefamenanu, North Central Timor Regency (TTU). Chicken semen used in this study came from 10 male native chickens with an age range of 2-3 years or with a spur length of 2-3 cm. This is the basis for selecting male livestock to produce quality cement which will be used as research material. This research used an experimental laboratory with a completely randomized design (CRD), which consists of 4 treatments and three replications so that there are 12 experimental units, namely: R1:Storage fresh cement over time (0 hours), R2:Storage fresh cement during the period ( 2 hours), R3: Storage of fresh cement for time (4 hours), R4: Storage of fresh cement for time (6 hours). The variables used in this study were: spermatozoa motility, spermatozoa viability, semen pH. The data obtained were analyzed using the Duncan Test of Variety Analysis. By using statistical software packages for the social sciences (SPSS. 20). The results showed that the mean spermatozoa motility in treatments R1, R2, R3 and R4, respectively, were mass motility of 4 ± 0, 4 ± 0, 4 ± 0 and 3 ± 0.6. Individual motility is 80 ± 00, 80 ± 00, 80 ± 00, and 80 ± 00. Viability 96 ± 02, 94 ± 04, 95 ± 73, and 91 ± 75. Semen pH 8 ± 05, 8 ± 00, 8 ± 05 and 8 ± 00. Statistical analysis showed that the treatment had a significant effect on the viability of native chicken spermatozoa. It was concluded that domestic chicken spermatozoa could survive for 6 hours in a storage media ColdBox containing ice cubes.

Abstract

This research was conducted to determine the characteristics of farmers and the effect of counseling support on the technical ability of raising beef cattle. This research was conducted in October 2019 in Fatoin Village and Manunain B Village, Insana District, North Central Timor Regency. The research was conducted at the Matani Farmer's Group in Manunain B Village with 14 members and the Ataubale Nunusili Farmer's Group in Fatoin Village with 16 members. The total respondents used in this study were 30 people. The types of data used in this study are qualitative data and quantitative data with the data sources used in the form of primary data and secondary data. Data was collected through observation and interviews with respondents. The results showed that the technical ability of the breeder was strongly influenced by the characteristics of the breeder (age, education, and experience) and extension support (method suitability, media suitability, and extension competence).

Abstract

This research was conducted in South Atambua District, Belu Regency for 5 months. The purpose of this study was to determine the success factors of artificial insemination of bali cattle in Atambua Selatan District. In this study using a survey method, data collection was done by interview and observation. The population of acceptors in this study amounted to 50 farmers with 523 cattle. The variables observed in this study were the characteristics of the breeder, the pattern of livestock rearing, the number of livestock ownership, Service Per Conception (S/C), Conception Rate (CR), and Calving Interval (CI). The results showed that the success rate of Artificial Insemination in Atambua Selatan District was based on Service per Conception with an average S/C value of 1.77; The Conception Rate is 48.63% and the Calving interval is 413.20 months. Factors that influence the success rate of Artificial Insemination in Atambua Selatan District based on Service Per Conception, Conception Rate and Calving interval, namely semen quality, inseminator skills, estrus detection and reporting estrus, AI techniques, feed quality and quantity.

Abstract

The purpose of this study was to determine the effect of shelf life in Beltsville Thawing Solution (BTS) cement on motility, viability, abnormality and degree of storage (pH) of landrace pig semen. The semen used was fresh semen from a 4-year-old Landrace boar. This study used an experimental method using a completely randomized design (CRD) with four treatments (P0 10%, P1 10%, P2 10% and P3 10%) and four replications so that there were 16 experimental units. The results showed that the BTS cement diluent was significantly different (P>0.05) on the motility of spermatozoa with the average value of each treatment being P0 (68.25%), P1 (58.25%), P2 (38.50%). and P3 (10.75%). The percentage of spermatozoa viability was significantly different (P<0.05) between treatments, where the P2 treatment was relatively the same as the P3 and P4 treatments but was higher than the P1 treatment with respective values P1 (83%), P2 (90.1%) , P3 (93.5%) and P4 (91.5%). Percentage of spermatozoa abnormalities resulting from analysis of variance (ANOVA) from each treatment there was a non-significant difference (P>0.05) where the values were P1 (8.2%), P2 (9.2%), P3 (8.1%) and P4 (9.2%). The degree of relative difference (pH) was significant (P<0.05) between treatments, where the treatment was the same as P2 but more than P4 treatment. On the other hand, P3 was relatively the same as treatment P1, P2 and P4, with the respective treatments being P1 (8.36), P2 (7.99), P3 (7.676) and P4 (6.83). It can be said that the use of different glucose concentrations in the diluent of egg yolk citrate semen with good quality, namely in the P3 treatment with a glucose concentration of 15%, the average percentage of individual motility was 64%, the percentage of live spermatozoa was 93.5%, the percentage of abnormal spermatozoa was 8.1%. and the average pH (degree so) of cement is 7.68.
