Abstract

This study aims to determine the effect of adding melon (Cucumis melo L.) juice to Lactated Ringer's-egg yolk extender on the intact plasma membrane (IPM) and morphological abnormalities of native rooster spermatozoa. Five ejaculate each from two native roosters (Gallus gallus domesticus) were divided into four equal volumes. Ejaculate was extended 1:10 (v/v) in Lactated Ringer's-egg yolk without or with the addition of of 2, 4, and 8% (v/v) melon flesh juice, respectively for groups T0, T1, T2, and T3. Extended semen was stored in a refrigerator (5°C) and evaluated every two hours. The results showed that IPM of all groups decreased (p <0.05) consistently, lasting more than 40% for six hours in the T0 and T1 groups and four hours in the T2 and T3 groups. The percentage of spermatozoa morphological abnormalities in all groups stored for six hours was higher (p <0.05) than before storage. However, it was not significantly different (p >0.05) from that which had been stored for two and four hours. It was concluded that native rooster semen extended in Lactated Ringer's-egg yolk without (group T0) or with 2% melon flesh juice (group T1) and stored at 5°C retained spermatozoa plasma membrane integrity of more than 40% and morphological abnormalities of less than 20% for six hours. While the addition of 4 % (T2) and 8% (T3) melon flesh juice maintained the percentage of IPM and spermatozoa morphological abnormalities for only four hours.

Abstract

Yoruba Ecotype Chicken (YEC) is characterized by hardiness, and better adaptation to prevailing tropical environment. However, its poor egg production has hindered its utilization for commercial production. Crossbreeding is a major tool used in improving desired traits in animals. The objective of the study was to evaluate egg production and quality characteristics in YEC and its crosses with Goliath (GG) and Sussex (SS). The study investigated egg production and egg quality characteristics using 120 sixteen-week-old YEC and its crosses. The findings of the study showed that egg parameters were significantly higher (p<0.05) and maturity occurred earlier (154 days) in YECxSS than in YECxYEC (146 days) and other YEC crosses. The study concluded that cross breeding improved egg production of YEC. Crossbred YEC x SS is therefore recommended for egg production in Nigeria.

Abstract

Bali cattle have advantages in terms of adaptation and fertilization rates, but tend to have slow growth rate because the rearing system is still grazing so that livestock growth becomes uncontrollable. This study aims to determine the peak of mating and calving estimation of Bali cattle (Bos sondaicus) that did not experience reproductive disorders, aged 4-7 years, belonging to smallholder farmers. The cattle were reared in semi-arid area of Netemnanu village, South Amfoang district, Kupang regency, Nusa Tenggara Timur. The method used was interviews with farmers, diagnosis of pregnancy through rectal palpation and ultrasonography. The results showed that the pregnancy rate was 86.20% (50/58).  Based on pregnancy data, it was known that the peak of mating would occur in December 2021 and estimated calving would reach its peak in September 2022.

Abstract

Pote goats are kept by the rural community in Bangkalan Regency, Madura Island, Indonesia. Estrus symptoms in goats are usually unclear, causing low fertility. This study aimed to determine the intracervical artificial insemination at early and mid-estrus on the Pote does. The 24 the does were randomly divided into two groups and estrous synchronization with PGF2α of 200 µg intramuscularly, twice injections with 11 days intervals. The T1 groups of estrus the Pote does were inseminated at early estrus (0-12 hours). Meanwhile, T2 groups of estrus the Pote does were inseminated at mid-estrus (12-24 hours after signs of estrus appeared. The insemination conducted artificially using post-thawed Boer semen. The observed variables were non-return rate at day 21 post-insemination (NRR21), and pregnancy rate (PR) based on abdominal palpation diagnosis. The result showed that post-thawed Boer buck was qualified (sperm motility more than 40%) for artificial insemination. All of the Pote does were estrus after twice PGF2α intramuscular injection with 11 days intervals. The onset of estrus was 48-72 hours after the second injection PGF2α. The NRR21 and PR ranged from 66.66-100% and 37.50-66.66%, respectively. The NRR21 and PR of the T2 group were higher than those of the T1 group. It could be concluded that intracervical artificial insemination on Pote the does at mid-estrus were more effective, resulting in higher NRR21 and PR than those at early estrus.

Abstract

Twelve healthy and not pregnant local cows, aged 3-6 years, 1-3 parity. The cows were synchronized using the PGF2α of 5 ml/cow intramuscularly, twice at 11 days intervals. The Estrus detection based on the scoring of van Eerdenburg was conducted 24 hours after the second prostaglandin injection three times daily for three days. The changes in cervical dilatation were observed at 0, 6, and 12 hours from the onset of estrus. The result showed that 8 of 12 cows were estrus after twice PGF2α injection. All the estrus cows showed mild cervical dilatation with liquid and transparent mucus (opening cervix score 1) at 0-hour observation. Six hours later, 62.50% of cows remained at opening cervix score 1, and 37.50% changed to opening cervix score 2 (optimum cervical dilatation with thick and transparent mucus). At 12 hours after the onset of estrus, 25% of estrus cows had cervical closure (opening cervix score 0, closed cervical with thick and turbid mucus), and 75% changed to opening cervix score 2. In this study, 75% of the cows experienced an optimum open cervix at 12 hours from the onset of estrus. It could be concluded that opening the external cervical canal of local Aceh cows reaches optimum at 12 hours from the onset of estrus.

Abstract

This study aims to determine the risk factors for dystocia in primiparous and pluriparous dams at the study site. Cases of dystocia, both maternal and fetal, were obtained as secondary data from records at the Situbondo Regency Animal Husbandry Service for year 2020 and 2021. Tracking on these secondary data was carried out to look for cows experienced dystocia and the owners' names and addresses for interviews using a questionnaire worksheet. Interviews were conducted in February - May 2022 to obtain data on the maternal breed, age, feeding, fetal sex, and exercise frequency during pregnancy of the cows. Dystocia in the working area of the Besuki Animal Health Center in Sitobondo Regency in 2020 and 2021 occured in 50 cows which included primiparous (26%) and pluriparous (74%) cows. Breed, age, feed, and sex of the calves were not significantly different (p >0.05) between primiparous and pluriparous dams. However, the frequency of the exercises differed significantly (p <0.05) between primiparous and pluriparous dams. It could be concluded that the dystocia of cows in the study area was dominated by pluriparous parturition with exercises factor as the main cause.

Abstract

This study aims to determine the effect of red dragon (Hylocereus polyrhizus) fruit peel extract (RDFPE) on spermatozoa motility and viability of hypercholesterolemic rats (Rattus norvegicus) as a model. Twenty male rats were randomly divided into negative control (NC), positive control (PC), treatment 1 (T1), treatment 2 (T2), and treatment 3 (T3) groups. All rats were given 2 mL of high cholesterol feed orally every day for 28 days. On day-15, all rats were measured for their blood cholesterol levels, followed by treatment for 14 days. Rats in the NC, PC, T1, T2, and T3 groups were treated with 1% Na-CMC, Simvastatin 10 mg/kg BW, and RDFPE of 500, 750, and 1000 mg/kg BW, respectively. On day-29, all rats were sacrificed to evaluate spermatozoa viability and motility. The results showed that spermatozoa viability and motility in the hypercholesterolemic rats (NC) group were the lowest (p <0.05) among the groups. Treatment of hypercholesterolemic rats with Simvastatin 10 mg/kg BW (PC) group showed higher (p <0.05) spermatozoa viability and motility compared to the NC group. RDFPE dose of 1000 mg/kg BW (T3 group) resulted in higher (p <0.05) spermatozoa viability and motility compared to other RDFPE doses (T1 and T2) and the control (NC) groups, and it was similar (p >0.05) compared with the Simvastatin treated (PC) group. It could be concluded that the administration of 1000 mg/kg BW ethanolic extract of red dragon fruit (Hylocereus polyrhizus) peel increased the viability and motility of spermatozoa of hypercholesterolemic rats (Rattus norvegicus) which were the same as the group of rats given Simvastatin 10 mg/kg BW.
