Abstract

This study aims to determine the prevalence of gastrointestinal protozoa on Bali cattle in Lopok Sub-District, Sumbawa District. The study was conducted from January to April 2021 by taking 100 samples of Bali cattle feces from 7 villages in Lopok Sub-District, Sumbawa District. Samples were examined by sedimentation and floating methods. Species identification was determined by the morphology of the protozoa. A total of 62 (62%) samples were positively infected with protozoa. There were 4 species of gastrointestinal protozoa found infecting Bali cattle, namely Eimeria sp., Blastocytis sp., Entamoeba sp., and Balantidium sp. Most of the protozoa found in this study were Eimeria sp. (54%) and Blastocytis sp. (5%). This study found 59 samples (59%) were infected by one type of protozoa, 3 samples (3%) were infected by two types of protozoa. Cattle aged 0-6 months (81%) had a higher prevalence rate and were more susceptible to protozoal infections than cows aged 7 months – 2 years (70.3%) and more than 2 years (45.2%).

Abstract

Aim of this research is to find the effect of laserpuncture shooting at growth points on body weight gain and growth rate of male Japanese quail. This research used 20 samples Japanese male Day Old Quail (DOQ) with complete randomized design research method. These samples were divided into four groups. Group P0 (control) was treated by laserpuncture everyday with power supply off for 5 seconds. Group P1 was treated by laserpuncture every day with power supply at 50 mWatt and the dose was 0.2 Joule for 5 seconds. Group P2 was treated by laserpuncture every three days with power supply at 50 mWatt and the dose was 0.2 Joule for 5 seconds. Group P3 was treated by laserpuncture every five days with power supply at 50 mWatt and the dose was 0.2 Joule for 5 seconds. The samples was reared until 42 days. The result of the research were obtained from weighing the body weight every week and then substracting the results from the previous week. The data was analyzed statictically using the Multivariate Analysis of Variance (Manova) and continued with Duncan test. Group P3 showed the best results compared to other groups.

Abstract

This study aims to determine the morphometric differences in the head of male and female Turi ducks. Ten male and ten female day-old ducks (DOD) were randomly selected by a lottery system from the population, raised, and had their head morphology measured using a digital caliper with an accuracy of 0.01 mm on the first day, and at the age of 2, 4, 6, and 8weeks. The result showed that male Turi duck had wider (p <0.05) head at the ages of 1 day, 2 and 6 weeks, head length and head height at the ages of 1 day, 2, 4, 6, and 8 weeks, rostrum width at the ages of 1 day, 4, 6, and 8 weeks, and rostrum length at the age of 2, 4, 6 and 8 weeks. There were no significant differences (p >0.05) in the head width at the ages of 4 and 8 weeks, rostrum width at 2 weeks, and rostrum length at 1day old male and female Turi ducks. Morphometric growth pattern showed that older Turi ducks (at a range of 1 day to 8 weeks) had larger (p <0.05) head morphometry. However, the cephalic index in male and female Turi ducks was not significantly different (p > 0.05) at all ages. It could be concluded that in general head morphometry was useful for determining male and female Turi ducks at the ages of 1 day, 2, 4, 6, and 8 weeks

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

Livestock production requires Sapudi rams, a breed native to Indonesia, to meet meat demand and food security. In artificial high-quality frozen semen is needed to spread Sapudi rams. To maximize the survival of spermatozoa during cryopreservation, semen should be stored in an extender. Green tea leaf extract (GTLE) and skim milk-goat egg yolk (SM-GEY) may be a good cryoprotectants due to their antioxidant properties. This study aimed to determine the effect of adding GTLE to the SM-GEY extender on the quality of Sapudi ram spermatozoa stored at 5°C. The fresh semen sample was divided into four different GTLE treatment groups, which each contained a 0.1 mL semen sample and a 25-mL extender of SM-GEY. Group T0: no GTLE added to SM-GEY; Groups T1, T2, and T3: 0.1 mL semen diluted in 25 mL SM-GEY with 0.05, 0.10, and 0.15 mg GTLE. Extended semen was then stored at 5°C, and its quality was evaluated daily for five days. The variables observed included spermatozoa motility, viability, and membrane integrity. Data were analyzed using one-way analysis of variance followed by Duncan's test using Statistical Program and Service Solution version 23. The result of this study was that adding 0.05 mg GTLE to 25 mL of SM-GEY extender significantly maintained the spermatozoa motility, viability, and plasma membrane integrity of Sapudi ram spermatozoa for three days at 5°C (p <0.05). Therefore, it could be concluded that adding 0.05 mg of GTLE to the SM-GEY extender preserved Sapudi ram spermatozoa's motility, viability, and membrane integrity for three days at 5°C.

Abstract

This study aimed to determine the quality of Ettawah crossbred buck semen diluted in skim milk, egg yolk-citrate extenders, or their combination, supplemented with epigallocatechin-3-gallate (EGCG). Semen was collected from Ettawah crossbred bucks using an artificial vagina. Six ejaculates were used for replication and divided into three extender treatments: T1, skim milk; T2, egg yolk-citrate; and T3, a combination of both, each supplemented with 1.5 µg/mL EGCG. The extended semen was stored in a refrigerator at 5 °C. Diluted samples were evaluated every 24 hours until spermatozoa motility declined to 30%, the minimum requirement for artificial insemination. The results showed that spermatozoa motility, viability, plasma membrane integrity, and morphological abnormality decreased during six days of storage at 5 °C. Spermatozoa motility remained above 30% for five days in T1 (36.50±1.22%) and T2 (41.67±2.06%), and for six days in T3 (43.33±1.03%). On day six, semen in the combined extender supplemented with EGCG (T3) showed significantly higher motility, viability, and membrane integrity, and lower morphological abnormalities (p <0.05) than the other treatments. In T2, all spermatozoa quality parameters were higher (p <0.05) than in T1. It can be concluded that the combined skim milk-egg yolk-citrate extender containing 1.5 µg/mL EGCG best maintained the spermatozoa quality of Ettawah crossbred bucks during six days of storage at 5 °C. Based on spermatozoa motility, the semen remained suitable for artificial insemination.
