Abstract

This study was conducted at Setia Kawan dairy cattle farming cooperative in Nongkojajar, Pasuruan, East Java to evaluate the effects of different antibiotic treatments on pregnancy sustainability in Holstein Friesian (HF) dairy cows infected with foot and mouth disease (FMD). The objective was to identify which antibiotics have minimal impact on pregnancy outcomes in FMD infected cows. A total of 106 pregnant HF cows infected with FMD were included in this study. Samples were selected using a purposive sampling method with inclusion criteria of pregnant HF dairy cows that tested positive for FMD. Four types of antibiotics were assessed, including enrofloxacin, oxytetracycline, amoxicillin, and penicillin-streptomycin. The results showed that among cows treated with enrofloxacin, 88.46% maintained pregnancy while 11.54% experienced abortion. For oxytetracycline, 73.08% of cows did not abort, whereas 26.92% did. In the amoxicillin group, 61.54% maintained pregnancy and 38.46% aborted. For penicillin-streptomycin, only limited data were available, with 23.07% maintaining pregnancy and no recorded cases of abortion. In conclusion, while variations were observed among different antibiotic treatments, statistical analysis indicated no significant association between antibiotic type and abortion rate in HF cows infected with FMD. Further studies with larger sample sizes are recommended to confirm these findings.

Abstract

Sex identification of Sun Conures (Aratinga solstitialis) is crucial for breeding and preservation, as well as increasing sun conure populations. These birds are sexually monomorphic. Therefore, Determination between male and female carried out by their morphology examination. The Polymerase Chain Reaction (PCR) method, utilizing molecular-based technology, was employed to determine the sex of Aratinga solstitialis in this study. The P2 and P8 primers were utilized in this method, which has been deemed suitable and accurate for sex identification through calamus samples. The research focused on two 28-month-old Aratinga solstitialis birds. Calamus samples were collected and subjected to PCR amplification using the extracted calamus. The resulting PCR products were then visualized using electrophoresis with a 1% agarose gel. In the electrophoresis photo, the presence of two bands indicated a female specimen, whereas a single band indicated a male specimen. The result of the gel electrophoresis research showed that both of the Aratinga solstitialis were male with one band of each bird on ranged from 300-400 base pairs. The result show that the Polymerase Chain Reaction method in terms for sex identification on monomorphic birds, especially Aratinga solstitialis birds is very effective to differentiate the sex of young birds and the adults.

Abstract

This study aimed to determine the effect of taurine on the enhancement of the spermatogenetic process in male mice (Mus musculus) induced by paraquat (PQ). Twenty-five male mice (Mus musculus) aged 2-3 months with a bodyweight of around 35 grams were divided randomly into five groups. The K + and the treatment group (P1, P2, and P3) mice were induced using PQ. PQ was given intraperitoneally (IP) twice a week for 21 consecutive days at a dose of 30 mg/kg BW. Two hours after the administration of PQ, P1, P2, and P3 groups were given taurine at a dose of 250, 500, and 1000 mg/kg BW/day for three weeks (Heidari et al., 2019). K- group was given distilled water (IP) only. On day-29, mice were sacrificed for testicles histopathological preparations with hematoxylin-eosin staining. Results showed that the mice exposed to PQ only (the K+ group) had a reduced spermatogenesis score compared to those of the K- group (p <0.05).  Taurine treatment on PQ-exposed mice was followed by an increase spermatogenesis score. The optimal curative dose of taurine was 500 mg/kg (P2 group). However, a higher dose (1000 mg/kg BW) of taurine resulted in a decline in the spermatogenesis score than those of at the 500 mg/kg. It could be concluded that treatment with taurine could enhance the spermatogenetic process of male mice (Mus musculus) induced by PQ.

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.
