Abstract

Goldfish (Carassius auratus L.), one of the most popular and freshwater ornamental fish to be cultivated in Indonesia. One obstacle in the cultivation of Carassius auratus L. is the high feed cost (60-70%) of the total production cost. The natural food source for fish Carassius auratus L. is Tubifex sp. which has a high nutritional content. The aim of the study was to determine the dosage of Tubifex sp. best for the growth and survival rate of goldfish (C. auratus L.). This research was conducted at the Laboratory of Water Quality and Aquatic Biology, Faculty of Animal Husbandry and Fisheries, Tadulako University for 2 month (January to March 2020). The experimental design used a Completely Randomized Design (RAL) with 5 treatments and 4 replications. The treatment in this study was the administration of silk worms with different doses (A = 6%; B = 8%; C = 10%; D = 12%; E = 14%). The variables measured included absolute weight growth, survival and water quality. Data were analyzed by analysis of variance (ANOVA), with further tests BNJ using Excel 2010 and Minitab 16 application programs. The results showed that the natural feed (Tubifex sp.) shows a significant growth in absolute weight, but has no effect on survival. The absolute growth of goldfish seeds was the highest in the feeding of Tubifex sp. with a dose of 12% of 14.82 ± 2.76 g with a survival rate of 90.63% ± 6.25. Water quality (temperature, pH, dissolved oxygen and ammonia) is still in accordance with the growth needs of goldfish fry.

Abstract

Produktivitas dalam usaha pemeliharaan ternak kambing memiliki peranan yang sangat menentukan untuk meraih hasil yang cukup optimal. Reproduksi induk merupakan gambaran dari kemampuan induk bereproduksi, terutama dalam kemampuan induk untuk melahirkan sejumlah anak dan kemampuan untuk menyusui selama anak periode prasapih. Jumlah anak sekelahiran (litter size) sangat menentukan laju peningkatan populasi ternak kambing, karena jumlah anak sekelahiran yang tinggi dan tetap hidup sampai sapih akan dapat mempengaruhi kenaikan populasi. Penelitian ini bertujuan untuk mengetahui seberapa besar tingkat produktivitas induk kambing di Desa Dolago Kec. Parigi Selatan Kab. Parigi Mautong. Produktivitas induk kambing di Desa Dolago baik, hal ini dapat dilihat dari tingginya kelahiran, dengan jumlah sebesar 111,11% serta dalam kurun waktu satu tahun jumlah anak ternak kambing yang lahir dari 18 ekor induk adalah 20 ekor terdiri dari 8 ekor jantan dan 12 ekor betina. Hal ini dapat menggambarkan bahwa tingkat produktivitas ternak kambing di Desa Dolago adalah baik.

Abstract

Turkey is a type of poultry from the order Galliformes, the genus Meleaagriss which is starting to get public attention for cultivation. The cultivation of turkey in Indonesia is still lacking, most of the breeders prefer other types of poultry. Turkey is a type of poultry that has the potential to be developed as a meat animal, because it has a large body size and is able to utilize feed ingredients in the form of grains and forage. This study aims to determine the growth of male turkeys aged 19-25 weeks at different energy levels. The research was carried out in the experimental cage of the Faculty of Animal Husbandry and Fisheries in South Sibalaya Village, Tanambulava District, Sigi Regency, on June 24 - July 29 2018. The study used a completely randomized design (CRD) with 3 treatments and 5 replications. The treatments are R1 = Rations with Metabolic Energy of 2800 Kcal/Kg, R2 = Rations with Metabolic Energy of 2900 Kcal/Kg, R3 = Rations with Metabolic Energy of 3000 Kcal/kg. The variables observed were rations consumption, body weight gain and rations conversion. The results showed that the treatment had a significant effect (P <0.05) on rations consumption, had no significant effect (P> 0.05) to increase of body weight and rations conversion. Using energy levels of 3000 Kcal/Kg gives a positive result on rations consumption for male turkeys aged 19-25 weeks.

Abstract

Previous studies have succeeded in isolating, and the basic sequence of mRNA encoding FAMeT Scylla olivacea. Several studies have noted that the FAMeT encoding mRNA sequence has differences in crustacean species. The aim of this study was to determine the relationship between S. olivacea and other crustaceans based on the FAMeT encoding mRNA sequence. The similarity of the FAMeT encoding mRNA sequences showed that several crustaceans had similarities to the FAMeT mRNA sequences of S. olivacea. The phylogeny tree analysis showed the existence of 2 clusters of the relationship between the mRNA encoding FAMeT of S. olivacea on the same branch as 2 other crab species: S. serrata and S. paramamosain. It was also found in Portunus trituberculatus and P. pelagicus and river prawn Macrobrachium rosenbergii. These findings indicated that the S. olivacea crab was monophyletic with 2 other mangrove crabs, namely the crab and the river prawn M. rosenbergii. So that describes a very close kinship relationship genetically. Meanwhile, the second branch consists of crustaceans such as Homarus americanus, Cherax quadricarinatus, Fenneropenaeus merguiensis, Metapenaeus ensis and Litopenaeus vannamei.
