Abstract

The swim up method is a method of selecting X and Y spermatozoa. This study aims to determine how resiquimod (R848) levels affect the percentage of X spermatozoa and Y spermatozoa in the semen of Etawah crossbreed goats (PE) resulting from sexing using the swim up method. This research was carried out from 1 - 30 January 2024 with the research object being male PE goats with a lifespan of 4 years. The research results were analyzed using variance, followed by Duncan's multiple range test to determine differences between treatments. In this study, four treatments were given, namely  (without R848),  (R484 0.3 μM),   (R484 0.6 μM), and  (R848 0.9 μM). Each treatment was repeated six times. The results of this study showed that the use of resiquimod (R848) did not have a significant difference in the percentage of X and Y spermatozoa. It can be concluded that it had no effect on the percentage of PE goat spermatozoa in the lower and upper layers.Keywords: Resiquimod (R848), Percentage of Spermatozoa, Swim up method, Goat PE

Abstract

The purpose of this study was to determine the performance and repeatability values of S/C, DO, and CI in the South Garut Farmers Cooperative. Reproduction data used were individual reproduction records of 162 Friesian Holstein dairy cows. The results showed that the average reproductive performance for S/C for parity 1 was 2.20 ± 0.797, parity 2 was 2.40 ± 0.974, parity 3 was 2.28 ± 0.947, parity 4 was 2.22 ± 0.965, and the total value of S/C was 2.28 ± 0.921. The DO value for parity 1 was 159.50 ± 80.838, parity 2 was 150.43 ± 73.874, parity 3 was 142.29 ± 56.689 days, parity 4 was 133.79 ± 42.678 days, and the total DO was 146, 50 ± 67.267 days. The CI value for parity 1 was 437.91 ± 80.144 days, parity 2 was 430.20 ± 75.211 days, parity 3 was 423.31 ± 57 days, parity 4 was 414.59 ± 42.470 days, and the total CI was 426, 5 ± 67.355 days. The repeatability value at KPGS for S/C was 0.17 ± 0.033, DO was 0.1 ± 0.040, and CI was 0.097 ± 0.040. These three reproductive properties show repeatability values in the low category

Abstract

Beta-lactoglobulin genetics is one of the whey proteins in cow's milk that can influence improvements in milk composition, production, and component levels. Reproductive disorders and clinical mastitis in livestock are often related to genetic, hormonal, and environmental factors. Research on the relationship between beta-lactoglobulin and cow reproduction is still very limited. Therefore, the aim of this study is to determine the relationship between beta-lactoglobulin genotype and clinical mastitis as well as reproductive disorders (dystocia, retained placenta, and endometritis). This research utilizes secondary data obtained from the KPBS Pangalengan headquarters, consisting of genotype examination results of betalactoglobulin and medical records of cows experiencing clinical mastitis and reproductive disorders. A total of 113 samples were collected. The data were analyzed using quantitative methods, followed by ChiSquare tests using Microsoft Excel and SPSS version 25.0 for data analysis. The results showed that the beta-lactoglobulin genotype was not associated with the incidence of clinical mastitis (p=0.509) or reproductive disorders such as dystocia (p=0.789), retained placenta (p=0.193), and endometritis (p=0.685). All test results indicated significance values ≥0.05. The conclusion of this study is that polymorphism beta-lactoglobulin does not have a significant relationship with clinical mastitis and reproductive disorders occurring in Friesian Holstein cows at Pangalengan area. Keywords: beta-lactoglobulin, clinical mastitis, dystocia, endometritis, Friesian Holstein cow, retained placenta.

Abstract

Domba merupakan ruminansia kecil penghasil daging, susu, kulit dan produk lainnya untuk memenuhi kebutuhan hidup manusia. Untuk mengoptimalisasikan populasi, perlu terjadinya reproduksi yang dapat dilakukan melalui kawin alami dan Inseminasi Buatan, melalui teknologi IB seekor pejantan dapat mengawini beratus-ratus betina. Penelitian telah dilaksanakan selama 4 minggu, dimulai sejak tanggal 1 Maret 2022 sampai dengan 29 Maret 2022. Penelitian bertempat di Lab. reproduksi Fakultas Peternakan Universitas Padjadajaran. Penelitian menggunakan domba lokal jantan dengan umur 3 tahun. Rancangan yang digunakan Rancangan Acak Lengkap, dengan 5 perlakuan dan 4 ulangan, yaitu  chilledsemen  ditambahkan dengan 0,25% sari kurma (P1), chilledsemen ditambahkan dengan 0,5% sari kurma (P2), chilledsemen  ditambahkan dengan 0,75% (P3), dan chilledsemen ditambahkan dengan 1% sari kurma (P4). Hasil penelitian menunjukkan bahwa keempat perlakuan berpengaruh tidak nyata terhadap motilitas dan viabilitas terhadap chilledsemen yang telah di campurkan oleh sari kurma. Dapat disimpulkan bahwa penambahan sari kurma 0,75% terhadap chilledsemen memiliki hasil yang terbaik di banding dengan 3 perlakuan lainnya secara kuantitatif memiliki hasil yang mendekati hasil kontrol positif (P1), sehingga sari kurma berpotensin untuk menaiki nilai motilitas dan viabilitas.
