Septiana Alafia Yusi Ardiyansyah — 2023-11-21

This study aims to identify the differences in reproduction performance of Ongole cross (PO), Limousine cross (Limpo), and Simmental cross (Simpo) in Kerek district, Tuban regency. Primary data was taken by interviewing inseminators and farmers, while secondary data was taken from the Fisheries and Animal Husbandry Department of Tuban regency. The total sample was 360 cows consisting of 30 PO, Limpo, and Simpo cows aged 3, 4, 5, and 6 years respectively which were calculated based on the Roscoe formula. Data was analyzed using the Simple Linear Regression and ANOVA followed by Duncan's multiple range test at a significance level of 95%. The results showed that the services per conception (S/C), conception rate (CR), and calving rate (CvR) were not significantly different (p >0.05) between PO, Limpo and Simpo cows. Meanwhile, days open (DO) and fertility status (FS) of PO cows were higher (p <0.05) than Limpo and Simpo cows. There was no significant difference (p >0.05) in DO and FS between Limpo and Simpo cows. The linear equation with age as a predictor (X) of S/C, DO, and CI (Y) values were not significant (p >0.05) in PO, Limpo, and Simpo cows. It could be concluded that the reproductive performance of PO cows was better than Limpo and Simpo cows.

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.

Effect of Peganum harmala seeds extract on the hepatic tissue structure and fetus of mice

Samira Musa Sasi — 2023-11-27

Peganum harmala is one of the most used plants for the treatment of many diseases. Its effective compounds have pharmaceutical and medicinal properties. This study aims to determine the effect of aqueous extract of harmala plant seeds on body and liver weight, aspartate aminotransferase (AST), alanine transaminase (ALT), and the histological structure of liver of mice, as well as the size of the fetuses sired by treated mice. Sixteen adult male mice were divided into two groups of eight. The first group (control) was given distilled water orally, while the second group received the aqueous extract of harmala seeds at a dose of 300 mg/kg bw for three weeks. three untreated females were housed with one treated male for mating. At the end of the treatment, six male mice of each group were weighed and killed. Liver was extracted, weighed and its enzymes were measured. Also, sections of the liver were prepared for histological examination. The results showed a decrease in the body weight of the treated mice and a significant increase in the average weight of the fetuses compared with the control group, as well as marked changes in the hepatic tissue structure. There was no impact of the extract on fetal body length, liver weight and hepatic enzymes (AST and ALT) of treated mice. Further studies should be conducted to determine a safe dose that does not affect any organ in the body, so that it can be used for the treatment of many diseases.
