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.

Abstract

High temperatures lead to oxidative stress, which can disturb spermatogenesis process. Watermelon (Citrullus lanatus) peel contain antioxidant expected to compensate oxidative stress due to heat stress exposure. This study aimed to determine the effect of watermelon rind ethanolic extract on the number of Leydig, Sertoli, and spermatogenic cells of rats exposed to heat (40°C). Twenty rats (Rattus norvegicus) were divided randomly into five groups. In the control group (T0) rats were not exposed to heat nor given the watermelon rind extract. T1, T2, T3, and T4 groups were exposed to heat for an hour daily and orally given placebo (1% Na CMC), 100, 200, and 400 mg/kg BW of watermelon rind extract (in 1% Na CMC). Rats were treated for 52 days, and sacrificed for the testicle collection. Hematoxylin-eosin stained histological slides were prepared for the examination of Leydig, Sertoli and spermatogenic cells. The results showed no significant difference (p >0.05) in the average number of Leydig cells in rats among groups. The number of Sertoli cells and spermatogenic cells of rats exposed to heat (T1) was lower than those of the normal rats (T0 group). The dose of watermelon rind ethanolic extract at 200 mg/kg BW (T3 group) and 400 mg/kg BW (T4) increased (p <0.05) the number of Sertoli and spermatogenic cells. It could be concluded that a dose of 400mg/kg BW of watermelon rind ethanolic extract maintained the number of Leydig cells, Sertoli cells, and spermatogenic cells of rats exposed to heat.

Abstract

Goats are small ruminants that are reared by the rural community for financial income and nutrition. This study was aimed to determine the effect of vitamin C addition in tris–egg yolk extender on the lifespan of Sapera goat spermatozoa stored in 5o C. Semen was collected from 1.5 years old Sapera male goat. The ejaculates were diluted in Tris-egg yolk (T-EY) extender added with 0, 0.2, 0.3, and 0.4 g vitamin C/mL extender for T0, T1, T2, and T3 groups, respectively. The spermatozoa motility, viability, and morphological abnormality were assessed along with storage at 5° C. The result showed that spermatozoa motility was the highest (p <0.05) in T1 compared to other groups and qualified for AI use for up to 72 hours. In 24 hours storage, the spermatozoa viability was not significantly different (p >0.05) among the groups. The spermatozoa viability in the T1 group was the highest (p <0.05) among the groups along 48-96 hours of storage. The spermatozoa morphological abnormalities of the T1 group was the lowest (p <0.05) compared to other treatment groups in the range of 24-72 hour storage. In the control group (T0), the less than 5% spermatozoa morphological abnormalities (qualified for artificial insemination) were only in the 24 hours storage, while those of the T1 group were up to 72 hours. It could be concluded that the addition of 0.2 g vitamin C/100 mL T-EY extender maintained the quality of Sapera goat semen for 72 hours at 5°C.

Abstract

This study aimed to determine the prevalence and factors that influence the incidence of retained placenta in dairy cows reared under an all-day cowshed housing system at KUD Tani Wilis, Sendang District, Tulungagung. This study used 216 dairy cows, that had already calved, that had been identified to have medical and reproductive records for data exploration. Data collected included the sex and weight of calf, single or twin calves, age of the dam, cowshed structure (floor, puddles on the floor, gutter, distance of cowshed to waste disposal, type of floor and roof, and sunlight exposure), feed of the dam (forage, concentrate, mineral supplements), frequency of retained placenta cases on calving intervals and days open of the dams. The prevalence of retained placenta was presented descriptively. Factors related to the retained placenta and its effect on calving interval and days open were analyzed by Chi-square test using Statistical Product and Service Solution (SPSS) software version 20 for Windows. The result showed that the prevalence rate of retained placenta was 19.91% of all dairy cow populations in the district. Furthermore, the sex of the calf, age of the dam, sunlight exposure, and the quantity of feed (forage and concentrate) were related to the retained placenta (p  <0.05). In addition, retained placenta increased along with extending of days open and calving interval. It could be concluded that the factors that influenced the prevalence of retained placenta were the sex of the calf, the age of the cow, the feed and concentrate, and the cowshed that is not facing the sun.

Abstract

This research aims to determine reproductive data on Sumatran elephants (Elephas maximus sumatranus) in the ETC and ERU of Way Kambas National Park, Indonesia during 1988-2021. Data recorded from the elephant population at both locations (ETC and ERU) includes the number, gender of elephants, elephant calves, ages and birth dates. Calving intervals and service periods were calculated from calving records of cows with a minimum parity of two. Data collection produced data on 47 elephant calves from 13 female elephants with at least twice the parity and 12 primiparous cows. Elephant reproductive records at ETC and ERU were: age (37.44 ± 9.03 vs. 29.75 ± 3.30 years), parity (2.78 ± 1.09 vs. 2.50 ± 0.58), and age at first birth (18, 11 ± 3.92 vs. 17.75 ± 0.50 years). While the calving interval was 1857.56 ± 870.81 vs. 1833.00 ± 305.18 days, and service period respectively 1229.44 ± 846.18 vs. 1210.50 ± 283.59 days, respectively. It can be concluded that the calving interval and service period for captive elephants at ETC and ERU were not much different and were within the normal range. Young cows showed better reproductive efficiency than older cows. Monitoring calves is very important. Further assistance is needed to improve elephant mobile veterinary services, increase diagnostic laboratory capacity, and educate camp managers, veterinary assistants, and mahouts about elephant diseases, their monitoring and treatment. In addition, the use of reproductive technology such as monitoring ovulation using ultrasound and carrying out artificial insemination was expected to increase reproductive efficiency.
