Abstract

Catfish is a highly favored source of protein in Indonesia. Catfish farming can be carried out using various types of feed and methods. This research aims to determine the effect of two types of fish feed with high (24%) and low (4%) protein content on several aspects of catfish cultivated using the pond/bucket culture method. The methods include catfish maintenance, physicochemical measurement, morphometric measurements, survival rate measurements, proximate testing, and histological preparations of catfish intestines and stomach. The results show that the TDS and pH values in the high-protein feed are higher than in the low-protein feed, while the temperature fluctuates. At the end of the observation, there is a significant difference in the morphometry of catfish fed with high-protein feed, where the body weight, head width, and body length are higher. The difference in body weight of catfish fed with high-protein feed is significantly higher (119.58±16.72 g) compared to those fed with low-protein feed (52.20±4.80 g). The average number of surviving catfish fed with high-protein feed is lower (27.60±8.23 fish) compared to the other group (44.00±2.55 fish). Proximate testing indicates that catfish meat with high-protein feed also has higher protein, fat, and carbohydrate content. Histological analysis shows that catfish with high-protein feed have longer villi and higher number of goblet cells, while the length of the gastric pits is lower. This research demonstrates that high-protein feed has an impact on fish quality, while ensuring water quality to reduce catfish mortality rates in catfish pond culture.

Abstract

Penelitian ini bertujuan untuk mengetahui jenis ektoparasit yang ditemukan, mengetahui produktivitas telur, serta mempelajari pengaruh ektoparasit terhadap produktivitas telur ayam F2 Mahkota Arab. Tahapan penelitian yang dilakukan yaitu; pemeliharaan ayam, pengambilan data telur, pengambilan sampel ektoparasit, preparasi ektoparasit, dan identifikasi ektoparasit. Analisis data meliputi jumlah ektoparasit per-inang, dominasi jenis ektoparasit, dan jumlah kumulatif telur (9 minggu). Hubungan jumlah ektoparasit dengan telur diuji dengan analisis korelasi Pearson (IBM SPSS Statistic 25) dengan taraf signifikansi 5%. Hasil penelitian menunjukan adanya 3 jenis ektoparasit yaitu Dermanyssus galliane, Menopon gallinae, dan Lipeurus caponis. Rerata jumlah telur ayam F2 Mahkota Arab (43.5 butir) lebih tinggi dari ayam Pelung (20 butir) sebagai salah satu ayam lokal. Hasil analisis korelasi pearson menunjukkan korelasi negatif antara jumlah total ektoparasit pada setiap pengambilan terhadap jumlah telur ayam F2 Mahkota Arab dengan nilai signifikansi sebesar 0,008 (P<0,05).Kata kunci: ektoparasit, F2 Mahkota Arab, produktivitas telurThe diversity of ectoparasites and its effect  on the egg productivity of F2 Mahkota Arab Abstract: This research aimed to identify the types of ectoparasites found, determine the egg productivity, and study the influence of ectoparasites on the egg productivity of F2 Mahkota Arab chickens. The research stages include chicken maintenance, egg data collection, ectoparasite sampling, ectoparasite preparation, and ectoparasite identification. Data analysis covers the number of ectoparasites per host, dominant ectoparasite species, and cumulative egg count over 9 weeks. The relationship between ectoparasites and egg productivity is tested using Pearson correlation analysis (IBM SPSS Statistics 25) with a significance level of 5%. The research results show the presence of three ectoparasite species: Dermanyssus galliane,Menopon gallinae, and Lipeurus caponis. The average number of F2 Mahkota Arab chicken eggs (43,5 eggs) is higher than that of Pelung chickens (20 eggs), one of the local chicken breeds. The Pearson correlation analysis indicate a negative correlation between the total number of ectoparasites in each collection and the number of F2 Mahkota Arab chicken eggs, with a significance value of 0.008 (P<0.05). Keywords: Ectoparasite, F2 Mahkota Arab, egg productivity
