Abstract

Penelitian ini dilakukan dengan tujuan untuk mengetahui pengaruh umur pada pejantan terhadap kualitas semen segar secara makroskopis. Penelitian dilaksanakan pada bulan Februari sampai Maret di Desa Bocor, Kecamatan Buluspesantren, Kabupaten Kebumen, Jawa Tengah. Penelitian menggunakan 6 ekor pejantan sapi Peranakan Ongole (PO) Kebumen yaitu sapi dengan umur 1,5 tahun sebanyak 3 ekor dan umur 2 tahun sebanyak 3 ekor. Metode mengelompokkan sapi berdasarkan umur. Semen ditampung satu kali seminggu setiap kelompok umur dengan menggunakan vagina buatan. Parameter penelitian adalah volume, warna, bau, konsistensi dan pH. Data yang diperoleh dianalisis dengan Uji t dan analisis deskripsi. Hasil penelitian menunjukkan bahwa perbedaan umur tidak berpengaruh nyata (P>0,05) terhadap kualitas semen secara makroskopis. Kualitas semen segar pada pejantan umur 1,5 tahun juga memenuhi standar untuk melakukan perkawinan.

Abstract

Objective: The objective of this research is to determine the relationship between body condition score (BCS) with estrus performance and reproductive performance in dairy cow post ovary hypofunction.Methods: Observational method by collecting primary and secondary data were used in this research. Primary data includes BCS and estrus performance. Secondary data includes reproductive performance. Purposive sampling method with criteria minimum parity 1 were used. Correlation and simple linear regression were used to analyze the data.Results: The results showed moderate correlation coefficient and regression equation of BCS with redness of vulva (0.531 and Y = 1.389+0.958 X), behavior changing (0.597 and Y = 0.75+0.896 X), mucus cervix intensity (0.503 and Y = 0.889+1.583 X), uterine erection (0.597 and Y = 1.500+1.792 X), service per conception (0.459 and Y = 4.33–1.09 X), estrus post-partum (0.594 and Y= 202.3–38.831 X) and days open (0.498 and Y= 217.271–40.832 X).Conclusions: The conclusion of this research is dairy cow with minimum BCS 3 is needed during mating post ovary hypofunction.

Abstract

Objective: To determine the increase in calcium (Ca) and zinc (Zn) content in Timor deer blood before and after velvet powder supplementation. This study also investigates the effect of velvet powder supplementation on male rats’ fertility status.Methods: This study employed twenty males Wistar rats weighing 200 – 250 g and aged 90 days. The sample was divided into four groups: the control group (T0), the25 mg kg-1 WB-1 velvet powder (T1), the 50 mg kg-1 WB-1 velvet powder (T2) and the 100 mg kg-1 WB-1 velvet powder (T3). Ca and Zn concentrations in rat blood were determined using an atomic absorption spectrophotometer (AAS) in the Feed Nutrition Laboratory at Universitas Diponegoro. The fertility status (sperm motility, mortality and abnormality) of male rat sperm was studied. In this study, statistical analysis was performed using analysis of variance (ANOVA). Results: The results revealed a significant difference P<0.05 ANOVA which was shown in blood Ca and Zn parameters before and after treatment, motility, sperm death and sperm abnormality in the rats.Conslusions: In conclusion, supplementation with 100 mg kg-1 WB-1 Timor deer velvet powder will improve the fertility status of male rats.
