Abstract

The purpose of this research was determine the effect and the best concentration of greentea extract in egg yolk citrate diluent for quality Sapudi sheep spermatozoa were measured in motility, viability and intact plasma membrane that was stored on cold temperature. The semen was devided into four groups : egg yolk citrate diluent, 0,05 % green tea extract in egg yolk citrate diluent, 0,1 % green tea extract in egg yolk citrate diluent and 0,15 % green tea extract in egg yolk citrate diluent. Spermatozoa quality was observed day 1, day 2, day 3, day 4 and day 5 after diluent. The data obtained was analyzed with the analysis of variance (ANOVA), followed by multiple range test duncan. The result showed that the higest precentage of motility, viability and intact plasma membran were obtained from 0,05 % green tea extract in egg yolk citrate diluent for 1 day of storage which were 85.83 ± 3.76, 91.16 ± 2.13 and 66.83 ± 6.49. The lowest precentage of motility, viability and intact plasma membrane were obtained from egg yolk citrate diluent for 5 day of storage which were 26.66 ± 6.05, 49.16 ± 6.43 and 26.66 ± 4.32. Conclution of this research was the addition of 0,05 % green tea extract can be used as a diluent could maintain the precentage of spermatozoa quality until 5 days after diluent.

Abstract

Objective from this research was to determine the relationship of udder morphometry which consists of the height of the front udder, the height of the rear udder and the circumference ofudder on milk production in the Bima District of West Nusa Tenggara. One of ways to choose a good lactational mare is to pay attention at the shape of the part external body which is udder. The sample had used 32 mares that were in lactation period. Milk production has been measured from the average milk production per day in the lactation period. Milking process in Bima District, West Nusa Tenggara has done in three to four times a day in the span of four to five hours per day. Body length had been measured from os thoracalis to os coxae, chest circumference had been measured from os vertebrae thoracalis to os thoracalis, posterior abdomen of pelvic to os pelvis and the last of os lumbar vetebrae. The research design in this study was survey on every wild mares rancher. Data that has been collected and processed using Multiple Regression with SPSS program version 23th. The result showed that there was a strong relationship between height of rear udder and udder circumference to milk production with back udder with height coefficient of 0.21 (P <0.05) and udder circumference was 0.11 (P <0.05) and equation in Y = 2.423 - 0.398LA + 0.793TAB. However, there is no significant relationship between the height of the front udder and milk production.

Abstract

Semen storage in cold temperatures might cause an increase in reactive oxygen species (ROS) production. This condition resulted in spermatozoa damage and quality decrease. This study was conducted to investigate the effects of α-tocopherol supplementation in diluents on the motility, viability, and plasma membrane integrity of Simmental bull spermatozoa after cooling. Semen samples were diluted in skim milk egg yolk supplemented with 0, 0.5, 1.0, and 1.5 mM α-tocopherol respectively for control, Tl, T2, and T3. Spermatozoa were evaluated for their motility, viability, and membrane integrity in cooling temperature (5°C). The daily evaluation showed that 1.5 mM α-tocopherol was the best in maintaining motility, viability, and plasma membrane integrity, while 1.0 mM α-tocopherol was only good for maintaining viability. Therefore, it can be concluded that α-tocopherol at the concentration of 1.5 mM was an efficient antioxidant supplement for Simmental cattle semen in skim milk egg yolk diluent.

Abstract

This case report aims to determine the response of estrus and pregnancy rates in dairy cows with ovarian hypofunction by administering a combination of gonadotropin hormones. The sample used was ten dairy cows that had been calving, were not pregnant, showed no signs of estrus for more than 60 days after the last calving and had ovarian hypofunction based on rectal palpation. All dairy cows were injected 300 IU PG-600, then divided into two groups, each injected with 100 and 300 IU hCG respectively for first group and second group, intramuscularly at the time of insemination. The results showed that the estrus response occurred in all cows, in 6-8 (6.8 ± 0.84) days (first group), and 6-7 (6.2 ± 0.45) days (second group). Trans-rectal palpation pregnancy diagnosis 60 days after artificial insemination showed that all dairy cows in both groups were pregnant. It could be concluded that the treatment of dairy cows suffering from ovarian hypofunction with a combination of 300 IU PG-600 and 100 IU hCG was sufficient to induce 100% estrus rates and 100% pregnancy rates.

Abstract

The process of spermatogenesis is sensitive to nicotine, a main component of cigarette smoke. This study aimed to observe the effect of nicotine injection on motility, viability, and membrane integrity of the spermatozoa of mice (Mus musculus). The mice were 10 weeks old, weighing about 20 grams, and in healthy and fertile conditions. Mice were adapted for 1 week by being given feed in the form of pellets and drinking water every day. Twenty of the mice were divided into four groups. Group K as a control was injected with 0.9% NaCl at 2.5 mg/Kg bw. Group P1 was injected with nicotine at 2.5 mg/Kg bw. P2 was injected with nicotine at 5 mg/Kg bw. Group P3 was injected with nicotine at 10 mg/Kg bw. The injection was carried out subcutaneously as much as 0.5 ml once a day for 35 days. Data analysis used the Analysis of Variances (ANOVA), followed by Duncan's Multiple Range Test. The results showed that the viability, motility, and membrane integrity of the spermatozoa decreased significantly (p <0.05) according to the increase in the dose of nicotine injected. It could be concluded that subcutaneous nicotine injection linearly decreased the motility, viability, and membrane integrity of the spermatozoa of mice.
