Publisher : Universitas Halu Oleo

This study aimed to determine the effect of edamame flour filler substitution on the physical quality of culled duck meatballs. The research material consisted of culled duck meat, tapioca flour, edamame flour, albumen, garlic, onion, salt, pepper, monosodium glutamate, sodium tripolyphosphate, and ice. The edamame flour filler substitution treatments were P0 (0%), P1 (5%), P2 (10%), P4 (15%), and P5 (20%) from total filler. Each treatment consisted of five replications. The parameters which tested were pH value, water holding capacity, cooking loss, and chewiness. The data on physical quality results were analyzed by analysis of variance using completely randomized design and if there was significantly (P<0.01), then that tests further by the Duncan's New Multiple Range Test. The results showed that the substitution of edamame flour filler to the level of 20% had a highly significant effect (P<0.01) on pH value, water holding capacity, cooking loss, and tenderness of culled duck meatballs. The edamame flour filler substitution at the level of 20% can increase the pH value, water holding capacity, and cooking loss, but decrease chewiness of culled duck meatballs.

Cassava leaf paste is an alternative substance in supporting the physiological performance of quail. Cassava leaf paste contains nutritional compositions such as water, ash, crude protein, crude fiber, fat, and carbohydrate. Cassava leaf paste has high crude protein and low crude fiber. The content of β-carotene and chlorophyll in cassava leaf paste has the ability as an antioxidant. Cassava leaf paste also contains phytochemicals such as flavonoids, saponins, tannins, sitosterol, and stigmasterol. The concentration of phytochemical has slightly higher flavonoid content, moderate tannins and saponins, and high sitosterol and stigmasterol. These phytochemicals act as antioxidants, antimicrobials, anti-inflammatory, improve the immunomodulatory system and reduce cholesterol. In addition, cassava leaf paste contains macro minerals such as P and Ca, as well as microminerals (Fe, Cu, Mn, and Zn). These minerals act as an antioxidant increases nutrient absorption, enhances immune response, and take part in mineralization during eggshell formation. Cassava leaf paste also has low levels of cyanide. Based on the nutritional content, phytochemicals, macro and micro minerals, and cyanide acid, cassava leaf paste has the potential to increase the physiological performance of quail.

This study aims to determine the factors that influence the demand for chicken eggs during the Covid-19 pandemic in Konda District, South Konawe Regency. Respondents in this study were 100 people who consumed purebred chicken eggs. The analytical method in this study uses multiple linear regression analysis in the form of natural logarithms. The results showed that the factors that influenced the demand for chicken eggs during the Covid-19 pandemic were the price of purebred chicken eggs, the price of fish, the average income of consumers, and the number of family members a significant effect on the demand for purebred chicken eggs. A 1% increase in the price of laying eggs will reduce the demand for laying eggs by 3.568%, a 1% increase in the price of fish will increase the demand for laying eggs by 2.604%.Keywords: demand; covid-19 pandemic; chicken eggs

Subclinical mastitis is an infectious disease that mostly caused by Staphylococcus aureus. The presence of Staphylococcus aureus in the udder and the milk cows caused by several factors such as cleanliness of cows and sanitation. The purpose of this study is to analyze the relationship between milking hygiene factors to the presence of Staphylococcus aureus in milk of dairy cows with subclinical mastitis. This research is explanatory research surveys with cross sectional method. The experiment was conducted at the Village Sruni, Boyolali with the number of samples are 47 respondents. Data analysis with chi square. The results showed that there are relationship cleanliness of cows with Staphylococcus aureus bacterial counts (p = 0.039), and milking hygiene with the number of bacteria Staphylococcus aureus (p = 0.027), no relationship sanitation equipment and cage sanitation with the number of bacteria Staphylococcus aureus (p = 0.008) and (p = 0.23). The conclusion is there is association between sanitation and hygiene milking in the presence of Staphylococcus aureus in milk of dairy cows with subclinical mastitis sufferers in dairy cattle farming village Sruni, Musuk, Boyolali. It is recommended to breeders to pay attention to cleanliness of cows, milking hygiene and sanitation equipment before milking.Keywords: hygiene, dairy cow’s milk, milking, staphylococcus aureus, subclinical mastitis

The study aimed to understand antimicrobial properties of plantaricin derived from L. plantarum IIA-1A5 and its inhibitory mechanism against Pseudomonas aeruginosa ATCC 27853 under SEM (scanning electron microscopy) observation. The inhibition of microbial growth was evaluated according to diameter of inhibitory zone. Scanning electron microscopy was then applied to observe the microstructure. The diameter of antimicrobial activity against Pseudomonas aeruginosa ATCC 27853 reached 6.52 mm in whey medium and 8.45 mm in whey+ medium (added with sucrose, tryptone and yeast extract). The experimental result clearly demonstrated the inhibition Pseudomonas aeruginosa ATCC 27853. Observation by SEM suggested that the antimicrobial activity of Pseudomonas aeruginosa ATCC 27853 related destruction of cellular morphology. The cell membrane was destroyed as indicated by the release of nucleic acid and reduction of membrane potential. In short, our experiment provided meaningful evidence on the future use of plantaricin IIA-1A5 as food preservative through disruption of cellular membrane causing leading to cell dying.Keywords: Plantaricin, Lactobacillus plantarun, Pseudomonas aeruginosa, antimicrobial activity

The aim of the study was to analyze the increase in body dimensions of post-weaning female Holstein Friesian (HF) calves fed with lactation cow concentrate with different levels of calf starter substitution. The material was 4 post-weaning female HF calves aged 4-5 months, with an average weight of 101.38 ± 14.21 kg. The feed consisted of elephant grass, calf starter (CS), and lactation cow concentrate (LCC). The study used a Latin square design, with 4 concentrate treatments, i.e. P1 (75% CS and 25% LCC), P2 (50% CS and 50% LCC), P3 (25% CS and 75% LCC), P4 (100% LCC); and 4 replications in 4 periods (each period in 1 month). The concentrate was given 1% BW in the dry matter; elephant grass and drinking water were provided in a measurable ad libitum. The research parameters were the increase in body dimensions (heart girth (HG), body length (BL), and withers height (WH)). The treatments had no significant effect (p>0.05) on the increase in body dimensions, were P1 (HG = 2.31 cm/month, BL = 4.75 cm/month, WH = 1.95 cm/month), P2 (HG = 4.23 cm/month, BL = 4.38 cm/month, WH = 2.23 cm/month), P3 (HG = 4.60 cm/month, BL = 4.38 cm/month, WH = 2.35 cm/month), P4 (HG = 4,10 cm/month, BL = 3.48 cm/month, WH = 2.18 cm/month). It was concluded that with sufficient quality forage feed, giving 100% LCC to post-weaning female HF calves could result in an increase in body dimensions that was relatively the same as the substitution of CS (25-75%) in LCC as concentrate feed.Keywords: post-weaning female HF calves, body dimensions, calf starter, lactation cow concentrate

Indonesia has the potential of muscovy duck resources with various characteristics and qualities that are spread throughout the region. muscovy duck has a larger body size than ducks but has a weakness in terms of lower egg production. To produce ducks with high body weight and egg production, Indonesian breeders often cross muscovy ducks with ducks. The use of a cross model with 4-crossbreeding is an efficient strategy, but genetic improvements need to be made to the two parents including the muscovy duck and the ducks itself because, in some crosses, sterile hybrid results will be obtained. The use of artificial insemination can be done to support the crossing of offspring in obtaining the desired production results. Therefore, a recording should be made to determine the quality of the offspring either using natural marriage or with the help of artificial insemination and its effectiveness on fertility in the next few periods. The use of marker-assisted selection (MAS) can help in the selection to get superior mutton traits and to find out the metabolic pathways related to the formation of the desired body weight and liver weight.Keywords: genetic quality, 4-crossbreeding, muscovy duck, marker-assisted selection (MAS)
