Abstract

This study aimed to determine the sex of Bangkok Zebra doves (Geopelia striata) based on external body morphometric measurements. A total of 32 doves were used, consisting of 16 females (8 bird each at 3 and 6 months of age) and 16 males (8 birds each at 3 and 6 months of age). Four morphometric parameters were measured: wing chord, antebrachium (forearm) length, longest primary feather, and longest tail feather. Wing and forearm lengths were measured using digital calipers with a precision of 0.01 mm, while the longest primary and tail feathers were measured using a ruler with 0.05 mm precision. The results showed that the average wing chord, longest primary feather, and longest tail feather lengths were significantly greater (p <0.05) in males compared to females. At six months of age, males also had a significantly longer forearm than females (p <0.05). However, no significant difference (p >0.05) was found in forearm length between sexes at three months of age. It could be concluded that wing and tail feather morphometrics can be used to distinguish between male and female Bangkok Zebra doves at both three and six months of age, except for forearm length at three months.

Abstract

Gender determination of Muscovy duck as early as possible is essential for the efficiency and effectiveness of duck production. This study aimed to determine the morphometric differences in prepubertal male and female Muscovy duck (Cairina moschata) as predictors of gender. This study used a split-plot design, with the observed variables cranium length, width and height, mandibular length, and rostrum length and width. This study used a total of 80 samples of duck heads consisting of 40 male and 40 female Muscovy duck heads, with ten heads each in the age group of 2, 4, 6, and 8 weeks, respectively. Results showed that the length, width, and height of the cranium, mandibular length, and rostrum lengthand width were greater in males (p <0.05) than those of the females in all age groups. It could be concluded that the morphometric size of prepubertal male Muscovy ducks head was greater than those of the female ones at the same age; thereby, it could be used to distinguish gender. Based on the morphometrics, further study can also be conducted to measure other body parts of the Muscovy duck apart from the cranium. In addition, it is necessary to study the morphometric measurements of the cranium in other poultry as a basis for identifying sex.

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 the administration of white guava (Psidium guajava L.) fruit juice on spermatozoa plasma membrane integrity (PMI), morphological abnormality, viability, and motility of lead acetate induced rats (Rattus norvegicus). Twenty-five male rats were divided into five groups: NC (negative control) group, rats were administered with distilled water twice daily at four-hour intervals; T0 (positive control) group, rats were administered daily with lead acetate 50 mg/kg bw and distilled water four hours later; T1, T2, and T3 groups, rats were administered daily with lead acetate 50 mg/kg bw and 0.5 mL of 25, 50, and 100% white guava fruit juice four hours later. The treatment of the rats was conducted for 14 days, and on day 15, all rats were sacrificed to assess the spermatozoa quality. Data was analyzed using ANOVA followed by Duncan's multiple range test at a confidence level of 95%. The results showed that exposure to lead acetate (T0) caused lower spermatozoa PMI, viability, and motility as well as higher spermatozoa morphological abnormalities (p <0.05) compared to those of the T0 group. Administration of white guava fruit juice starting at a dose of 25% (T1) resulted in higher spermatozoa motility, viability, and PMI as well as lower spermatozoa morphological abnormalities (p <0.05) compared to rats in the T0 group. It could be concluded that white guava fruit juice maintained the spermatozoa quality of lead acetate induced rats.
