Abstract

This study investigated the characteristics of concentrated yogurt made from goat milk with the addition of black rice extract. The inclusion of black rice extract aimed to provide a source of antioxidants and natural coloring, as it is rich in flavonoids, particularly anthocyanins. The primary materials used in this research were goat milk, a dry yogurt starter, and black rice extract. The experiment was conducted in several stages: preparation of black rice extract, yogurt production, and concentrated yogurt production. A randomized complete block design (RCBD) was employed, with treatments involving varying levels of black rice extract (0%, 2%, 4%, and 6%), each treatment repeated five times. The yogurt starter, containing probiotic lactic acid bacteria (Bifidobacterium longum, Lactobacillus rhamnosus, Lactobacillus casei, Lactobacillus helveticus, Lactobacillus bulgaricus, Lactobacillus acidophilus, and Streptococcus thermophilus), was used to facilitate the fermentation of milk into yogurt. Parameters measured included yield, pH, total titratable acidity, instrumental color indices (L*, a*, b*, whiteness index, hue, and chroma), total phenolic compounds, antioxidant activity, total lactic acid bacteria (LAB), texture, and proximate composition (moisture, ash, fat, and protein content). The addition of black rice extracts up to 6% resulted in higher protein and total lactic acid bacteria levels compared to the control. Additionally, black rice extract improved the color characteristics of concentrated yogurt made from goat milk.and gastrointestinal tract development in broiler chickens.

Abstract

This study aimed to assess the effects of coconut water kefir (CWK) supplementation on the production performance, carcass characteristics, and gastrointestinal tract morphology of broiler chickens. A total of 400 broiler chickens were used and divided into four treatment groups with five replicates, each containing 20 chickens. The study followed a completely randomized design (CRD). The treatment groups were as follows: T0 (control, no CWK supplementation), T1 (5% CWK), T2 (10% CWK), and T3 (15% CWK). The results indicated that CWK supplementation significantly influenced production performance, including feed intake, final body weight, weight gain, feed conversion ratio, and feed efficiency ratio. Furthermore, CWK supplementation also had a significant effect on carcass traits, such as carcass weight, breast percentage, thigh percentage, and abdominal fat, as well as on gastrointestinal tract parameters, including jejunum percentage, jejunum length, and ileum length. The optimal results were obtained from the 10% CWK supplementation (T2). In conclusion, CWK supplementation effectively improved the production performance, carcass yield, and gastrointestinal tract development in broiler chickens.

Abstract

This study aimed to evaluate the effect of adding fermented biomass from a combination of pineapple waste and Indigofera leaves on nutrient digestibility in broiler chickens, both in vitro and in vivo. The materials used included 21-day-old broiler chickens, finisher-phase broiler rations, pineapple waste, and Indigofera leaves. A completely randomized design (CRD) was applied, consisting of five treatments with three replications each. The treatments included different levels of fermented biomass addition to the broiler rations: P1= 100% pineapple waste, P2= 98% pineapple waste + 2% Indigofera, P3= 96% pineapple waste + 4% Indigofera, P4= 94% pineapple waste + 6% Indigofera, and P5= 92% pineapple waste + 8% Indigofera. The results showed that the addition of fermented biomass from pineapple waste and Indigofera leaves had a significant effect (P0.05) on increasing crude protein digestibility and crude fiber digestibility. In conclusion, incorporating fermented biomass of pineapple waste and Indigofera into broiler rations improves protein and fiber digestibility, with the optimal combination being 92% pineapple waste + 8% Indigofera.

Abstract

This study aimed to determine the nitrogen retention in local sheep fed dwarf elephant grass (Pennisetum purpureum cv. Mott) and indigofera (Indigofera zollingeriana). A completely randomized design (CRD) was used, consisting of four treatments with four replications each. The dietary treatments included: T= 100% dwarf elephant grass, T= 95% dwarf elephant grass + 5% indigofera, T2= 90% dwarf elephant grass + 10% indigofera, and T= 85% dwarf elephant grass + 15% indigofera. The parameters measured were dry matter intake (DMI), dry matter digestibility (DMD), nitrogen (N) intake, N retention, and average daily gain (ADG). The results showed that DMI, DMD, N intake, N retention, and ADG were significantly (P0.05) influenced by the dietary treatments. Based on these findings, the combination of 95% dwarf elephant grass and 5% indigofera was the most effective in improving DMI, DMD, N intake, N retention, and ADG in local sheep.

Abstract

This study aimed to determine the physiological response of Madura cattle and Limura cattle (Limousin x Madura) to the tropical environment. The research was conducted in Galis District, Pamekasan Regency from July to August 2024. The sample consisted of 50 Madura and Limura cattle, selected by purposive sampling. The parameters observed included rectal temperature, respiratory frequency, heart rate frequency, Heat Tolerance Coefficient (HTC), as well as the microclimate of the pen, which included air temperature, relative humidity (RH), and Temperature Humidity Index (THI). The results showed that the average THI at the research site was 83.24. The average rectal temperature (C) in the morning, afternoon, and evening for Madura and Limura cattle were as follows: 37.71.5, 38.70.4, 37.20.7 for Madura cattle, and 38.60.5, 38.90.3, 38.50.3 for Limura cattle, respectively. The mean respiratory frequency (times/minute) in the morning, afternoon, and evening for Madura and Limura cattle were: 23.53.4, 28.66.8, 23.35.2 for Madura cattle, and 25.62.0, 30.32.0, 26.73.1 for Limura cattle, respectively. The mean heart rate (times/minute) in the morning, afternoon, and evening for both groups were similar: 65.34.2, 69.59.8, 65.16.7 for Madura cattle, and 65.43.8, 69.811.8, 66.54.2 for Limura cattle, respectively. The mean Heat Tolerance Coefficient (HTC) for Madura and Limura cattle were 2.10.23 and 2.20.1, respectively. It was concluded that both Madura and Limura cattle exhibit similar responses in terms of heart rate and respiration rate. However, Madura cattle have lower rectal temperatures than Limura cattle. The Heat Tolerance Coefficient (HTC) was found to be higher in Limura cattle compared to Madura cattle.

Abstract

A symbiotic culture of kombucha (SCOBY) has the potential to act as a probiotic source of lactic acid bacteria, which can be combined with fermented beverage starters using fresh or reconstituted milk as a medium. This study aims to evaluate the effectiveness of kombucha in producing fermented milk products with microbiological characteristics. The experimental design used was a completely randomized factorial design with two treatment levels: skim milk concentration and kombucha concentration. The parameters observed included total lactic acid bacteria, pH, and total lactic acid. Data were analyzed by ANOVA using IBM SPSS Statistics program 29, and if significant effects were found, Duncan's post-hoc test was conducted. The results showed that using kombucha as a starter had a very significant effect (P0.01) on all three variables observed. The amount of lactic acid bacteria (LAB) in the fermented milk met the SNI standard, with a concentration of 7 log CFU/ml. It can be concluded that kombucha can be used as a starter in fermented milk production. Although the percentage of lactic acid levels and pH values are not yet listed in the Indonesian National Standard, both pH value and lactic acid levels showed a very significant effect. A higher percentage of kombucha starter led to higher lactic acid content, which is a result of bacterial metabolism. Additionally, a higher percentage of kombucha starter resulted in a lower pH value in the kombucha-fermented milk.
