Abstract

The purpose of this study was to observe the reproductive performances of Sumba Ongole (SO) cows inseminated with frozen Belgian Blue (BB) semen. This research was expected to be used as a reference in the cow’s maintenance, especially in the implementation of Artificial Insemination (AI), as well as for subsequent studies. Parameter of this study includes the signs of estrus symptoms, S/C ratio, CR, NRR, and pregnancy time. The results showed a large value of S/C for cow SO 2.60±1.81, great value for cattle CR SO was 40%, the value of NRR was 60%, and the pregnancy time SO was 273.80±4.08. It is concluded that reproductive performance of SO cows are good, using SO cows to cross with BB cow is possible to do.

Abstract

The purpose of this study was to observe the macroscopic and microscopic quality of Bronze turkey fresh semen on various ages. The observed toms were at the ages of 9 to 10 months (P1), 13 to 14 months (P2), and 17 to 18 months (P3), with each taken from 3 different toms. The collection was done by abdominal massage, and collected for 3 times a week in triplicate. This data was analyzed by analysis of variance (ANOVA) in a completely randomized design, followed by Duncans New Multiple Range Test (DMRT) if there was any difference. The results showed that the average volume of turkey fresh semen were P1 (0.16 ± 0.04 ml), P2 (0.13 ± 0.02 ml), and P3 (0.10 ± 0.02 ml). The average pH of fresh semen were P1 (7.19 ± 0.05), P2 (7.12 ± 0.10), and P3 (7.06 ± 0.06). The average motility percentage of fresh semen were P1 (78.11 ± 1.38%), P2 (82.55 ± 1.17%), and P3 (74.55 ± 4.16%). The average viability percentage of fresh semen were P1 (78.63 ± 1.55%), P2 (83.26 ± 1.54%), and P3 (79.20 ± 1.06%). The average abnormal percentage of spermatozoa were P1 (3.01 ± 0.04%), P2 (3.04 ± 0.88%), and P3 (3.21 ± 0.44%). In conclusion, the best fresh semen quality is found on toms aged from 13 to14 months (P2). Furthermore, at the age 17 to18 months and more, the semen quality was decreased.

Abstract

The purpose of this study was to observe the effect of extender and cooling rate on the quality of frozen thawed semen of Bali bull (Bos sondaicus). The experiment was conducted at Laboratory of Animal Biotechnology, Faculty of Animal Husbandry, Andalas University. A completely randomized design of factorial 2 x 3, 2 different extenders and 3 cooling rates with 3 bulls as the replicate. Data were analyzed using analysis of variance (ANOVA). The first factors was extender such as tris citrate egg yolk (TCEY) and tris citrate soy milk (TCSM). The second factors was the cooling rate such as: 15ºC/min, 10ºC/min and 5ºC/min. Variables were: motility, viability, abnormality, and membrane integrity. The results of treatment of TCEY extender on the average of motility 42.67±5.17%, viability of 53.78±3.79%, abnormality of 18.89±1.07%, and membrane integrity of 35.44±3.01%. The effect of cooling rate of 10°C /min has the highest semen motility of 44.35±5.28%, viability of 57.17±1.18%, abnormality of 17.84 ± 0.23 % and membrane integrity of 36.83±2.12%. The interaction between extender and cooling rate was founded significant different (P<0.05). Otherwise of extender and cooling rate on post-thawed of motility, viability and membrane integrity, had no difference (P>0.05) on semen abnormality. It can be concluded that tris-citrate egg yolk (TCEY) extender with cooling rate of 10ºC / min were the best semen motility, viability, and membrane integrity of spermatozoa.
