Growth and survival rate of freshwater lobster (Cherax quadricarinatus) fed different forage feed

Lobster is among freshwater crustaceans which is potentially cultivated in aquaculture system. This present study was conducted to determine the growth and survival rate of freshwater lobster Cherax quadricarinatus fed different forage feed. The experimental methode used a completely randomized design consisted of 4 treatments in triplicate: commercial diet (PL), commercial diet and carrots (PW), commercial diet and potatoes (PK) and commercial diet and sweet potatoes (PU). The experimental lobsters were 5-7 cm in size and 6-8 g in weight. Results indicated that forage feeding can affect the total weight and length, weight gain, specific growth rate and survival rate of lobster. Data showed the best weight gain and specific growth rate were found in PW (34.37±0.30%) and (1.05±0.03%), respectively. The lowest survival rate was seen in PU at 86.67%. However, the best feed conversion ratio gained by PL at 1.74±0.09. This study suggested that the combination of commercial diet with carrots provided the best growth performances in freshwater lobster Cherax quadricarinatus.

Drying temperatures on the functional properties of purple-fleshed sweet potato

ABSTRACT: Purple-fleshed sweet potatoes are rich in phenolic compounds, such as anthocyanins, and also exhibit hypoglycemic properties. Anthocyanins are natural antioxidants with the capacity to inhibit or delay injuries caused by free radicals. Drying is one of the most commonly used vegetable preservation methods; although,it has parameters that affect the sensory and physicochemical properties of the final product. The present study assessed the impact of drying temperatures (40, 50, and 60 °C) on the purple-fleshed sweet potato. Cut, unpeeled potato slices of 4 cm in diameter and 3 mm in thickness were dried in an oven with hot air circulation. The effect of the different temperatures on the antioxidant capacity, phenolic compound content, and total and monomeric quantities of anthocyanins in purple sweet potato were measured, and a mathematical model describing the drying kinetics was determined. According to the results observed, the process at 40 °C better preserved the phenolic compounds; however, drying at 50 °C was more efficient for conserving the antioxidant capacity measured by the H + capture method performed by DDPH, and for the total and monomeric quantities of anthocyanins. The mathematical models that best described the kinetic curves were those of Henderson and Pabis, and Page.

Indonesia is a paradise for plants, with numerous advantages for human life. It is possible to process Indonesia's natural resources to support the family economy while also benefiting health and being useful in treating various diseases, and many of these resources contain the vitamins that the body's organs require to increase energy. The health advantages of soursop plants are substantial, and the fruit is tasty to consume as is. Sometimes it grows naturally in people's yards; at other times, it is planted intentionally by the community for economic purposes. Apart from the fruit, soursop leaves can also be used to treat cholestorel when combined with additional spices such as betel leaves and a pinch of salt. Making soursop juice is simple if the fruit is ripe, although soursop fruit that is not ripe yet can be fried and the taste is similar to sweet potatoes. The business potential related with soursop seed planting are considerable. Along with the fruit, the leaves are beneficial for health since they contain a variety of vitamins that the body need.

Effect of Vine Length and Leaf Removal on Growth and Yield of Sweet Potato [Ipomoea batatas (L.)] in the Wet Middleveld of Eswatini

Sweet potato (Ipomoea batatas L.) is an economically important food crop in Eswatini. Since its introduction, numerous agronomic research activities were carried out in agricultural research centers, non-governmental organizations, and universities. However, information on the correct vine length for planting to improve sweet potato root yield in Eswatini is scanty. Therefore, this study aimed at helping farmers with the correct vine length to be used for improved growth and yield of sweet potatoes. A field experiment was conducted at the Luyengo campus, crop production farm during the 2019/2020 crops season. It was laid in a Randomized Complete Block Design (RCBD) in a factorial arrangement with three replicates. The treatments were vines planted with or without leaves and different vine lengths; 25 cm, 30 cm, and 35 cm. Kenya white variety was used. Data were collected on growth and yield parameters. Results showed that leaf removal yielded significantly (P<0.05) lower than non-leaf removal. This may be attributed to delayed photosynthetic activity in the former. The Vine length had no significant effect on yield. It is concluded that vines with leaves be used as planting material, and the length of vines to be used for planting should be 25 to 30 cm.

Provisioning food given by visitors to alpha-male long-tailed macaques at recreation forest, all of them are halal

The long-tailed macaque (Macaca fascicularis Raffles, 1821) is a non-human primate (NHP) species with social status in its group. Macaca fascicularis living in groups and social castes. Alpha males lead their group. Alpha males will have greater access to food than individuals with lower social castes. The content of feed eaten by animals, of course, will affect health. Various biological processes occur, from the food eaten by animals to affect the health of human life. If the food eaten is toxic, it will be hazardous to the animal's metabolism for life. According to a Muslim perspective, how much better food can be eaten is included in Halal products. Including, in this case, food ingredients for feed, if it comes from ingredients that are included in the halal category, this will provide animal welfare. This study seeks to explain how visitors' feed types (provisioning food) to alpha-male Macaca fascicularis at Mbah Agung Karangbanar Recreation Forest, Banyumas, Central Java, Indonesia. This study used behavioral coding to measure the frequency and quantity of eating behavior for ten days based on visitor feeding. The remainder of the provisioning food found is recorded as data on the type of provisioning food. Based on the study results, the alpha-male was noted to eat provisioning food such as peanuts, bananas, sweet potatoes, snacks, and foods mixed with soy sauce given by visitors. All of them are halal because they eat visitors every time they come to a tourist location. Alpha-male was noted to have no interest in the carcasses found, so they did not eat them.
