Abstract

Semen extender is closely related to the success of artificial insemination to achieve maximum results. Extender aims to increase the volume of semen, provide food substances as a source of energy for spermatozoa provide buffers to maintain pH, osmotic pressure, and electrolyte balance, and prevent the possibility of germ growth. This study aims to determine the effect of extender on the quality of Bali bull spermatozoa through an alternative approach, one of which uses Tris-Egg Yolk powder extender, which is efficient and effective. The study was designed randomized, with three treatments and five replications. The treatment combinations were P0 (Tris-Fresh Egg Yolk 20%), P1 (Tris Oven Egg Yolk 20%), and P2 (Tris-Commercial Egg Yolk 20%). The results of analysis of variance showed that in the parameters of progressive motility, viability, abnormality and intact plasma membrane, treatment of P0 (Tris-Fresh Egg Yolk 20%) tended to be similar as treatment P1 (Tris-Oven Egg Yolk 20%) (P>0.05), but in P2 (Tris-Commercial Egg Yolk 20%) was significantly lower (P<0.05) than P0 and P1. It can be concluded that oven egg yolk powder mixed with tris solution can maintain sperm quality after dilution. Keywords: Oven egg yolk powder, commercial egg yolk powder, buffer solution

Abstract

Bovine Brucellosis is endemic in Polewali Mandar Regency with a prevalence above 2%. Control programs implemented through active and passive surveillance, public awareness of the impact of the disease, and tests and slaughter have not been able to reduce the prevalence rate. This study aimed to examine the impact and risk factors of brucellosis on the productivity of beef cattle in Polewali Mandar Regency. A total of 100 primary data from cattle farmers related to brucellosis were used in this cross-sectional study. Descriptive analysis was employed to determine the parameters that were important in the occurrence of brucellosis. To establish risk factors, a univariate logistic regression analysis was carried out and revealed that odds of infection were significantly higher in history of abortion (OR = 11.82, 95% CI: 4.08 - 34.19,   p < 0.001) and in gestational age (OR = 0.0214, 95% CI: 0.0063 - 0.0724, p < 0.001) and in dry season than wet season (OR = 14.89, 95% CI: 4.97 - 44.62, p < 0.001).  The brucellosis control program through mass vaccination must immediately become a recommendation for regional and central governments to reduce brucellosis transmission to prevent economic impacts and losses for farmers, particularly the public health risk. Keywords: brucellosis, beef cattle, impact, risk factor, productivity

Abstract

This study aimed to determine the effect of cooking and level of vegetable addition and their interaction on the organoleptic quality of chicken nuggets. The research design consisted of 2 factors: the first factor was vegetable cooking treatment (fresh and steamed), and the second factor was vegetable addition level (0%, 5%, 10%, and 15%). The parameters measured were the organoleptic quality of chicken nuggets (color, texture, aroma, taste, t and acceptance/hedonic). The results showed that cooking treatment had no effect (P>0.05) on the organoleptic quality of nuggets, but the level of vegetable addition affected (P<0.05) the organoleptic quality of nuggets. Increasing the level of vegetable addition decreased the color value of L*, a*, but increased the color of b*. Besides, the organoleptic test decreased the attribute scores of color, aroma, taste, and texture but was still accepted by panelists up to 15% vegetable addition level. There was no interaction between cooking treatment and the level of vegetable addition on the organoleptic quality of nuggets. From this study, it can be concluded that the best treatment is using fresh vegetables up to 15% addition level. Keyword: Chicken Meat, Broccoli, Carrot, Chicken Nuggets, Organoleptic

Abstract

Waste treatment (WT) was one way to increase the income of small-scale goat farmers. Many factors influence breeders to adopt technology, including the subjective norm (SN) factor. This study aims to determine the effect of subjective norms (SN) consisting of the influence of informal leaders (IL), Family (F), extension (E) /Training Officer (TO), and peer groups (FG) or farmer neighbors (FN) on the behavior of farmers in feces waste treatment (WT). The research was carried out in West Sulawesi Province, precisely in Polman and the Majene Regencies, which were goat farming centers. The respondents were 50 in the Majene district and 100 in the Polman district. The determination of the sample was carried out randomly at the location of the goat breeding center (GBC). The research variable consisted of the behavior of farmers in adopting technology (AT), which consisted of five levels: feces disposed of (score 1), not processed and used alone (score 2), not processed and sold (score 3), processed and used alone (score 4). It was processed and sold (score 5). Independent variables consisted of subjective norms, including the Community Leader (CL) (X1), Family (F) (X2), Extension Workers (EW) or Technical Officers (X3), and Neighbors (N) or colleagues (C) influence (X4). The linear regression model was used to predict the F-test and t-test. The results showed that SN affects breeders’ behavior in processing goat livestock waste (GLW). The variable influence of EW, F, and N was a component of SN that influenced the behavior of breeders, to increase the adoption of WT technology, the role of EW must be increased in assisting farmers in adopting WT technology. Keywords: Goat, subjective norm, adoption, extension officer, Family member

Abstract

This study aimed to evaluate the antioxidant activity and organoleptic quality of salted eggs enhanced with varying concentrations of pandan (Pandanus amaryllifolius) leaf extract. A Completely Randomized Design (CRD) was employed with four treatment levels (0%, 15%, 30%, and 45%) and three replications. Antioxidant activity was determined using the DPPH (2,2-diphenyl-1-picrylhydrazyl) method, while organoleptic properties were assessed using a standardized Likert scale. The addition of pandan leaves had a highly significant effect (P<0.01) on antioxidant activity and a significant effect (P<0.05) on IC₅₀ values. All treatments exhibited strong antioxidant capacity, with IC₅₀ values below 50 ppm. The 15% pandan leaf treatment yielded the most desirable color, texture, taste, and overall acceptance, while 45% addition produced the most favorable aroma. The findings demonstrate that pandan leaves can serve as a natural antioxidant source and sensory enhancer in animal-derived products. This research provides important evidence that using tropical herbal additives such as pandan leaves can enhance the functional quality of traditional poultry products, contributing to innovation and sustainability in livestock-based food processing. Keywords: Salted egg, pandan leaves, organoleptic quality, antioxidant activity

Abstract

To ensure safe consumption and substitution in the production of urea multi-nutrient molasses block (UMMB), adhesives must be used to bond the raw materials. While cement is one of the primary adhesive materials used, its inorganic material means that its use in feed should be restricted. To address this issue, a study was conducted to evaluate the quality and shelf life of UMMB with tapioca meal as an adhesive substitute for cement. The study used a completely randomized design (CRD) with two factors. The first factor, A, involved substituting cement with tapioca meal., i.e., cement 100% (T0); cement 75% and tapioca meal 25% (T1); cement 50% and tapioca meal 50% (T2); cement 25% and tapioca meal 75% (T3); and tapioca meal 100% (T4), respectively. The second factor, B, is the shelf life, e.g., 0 days (as H0), 15 days (H15), and 30 days (H30), respectively. The study found that tapioca meal as a natural adhesive substitute for cement in the production of UMMB should be limited to a maximum of 50%. The study also revealed that the interaction between the substitution of cement with tapioca meal and the shelf life significantly affected water absorption and total plate count (TPC) but not the density of UMMB. This information could be used to help ensure the safe and effective production of UMMB. Keywords: Cement, Tapioca Meal, UMMB

Abstract

The research aimed to analyze the effects of adding rubber leaf (Hevea brasiliensis) flour in non-AGP commercial rations on the blood cholesterol levels of broiler chickens. The materials used were 200 heads of Day Old Chick (DOC) unsex from MB-202 strain, non-AGP commercial ration containing 22% protein, and rubber leaf flour with a tannin content of 2.5% DM basis. The experiment was designed using a completely randomized design (CRD) with four treatments and five repetitions, and each repetition unit consists of 10 DOCs. The treatment was the addition of rubber leaf flour by 0% (P0), 5% (P1), 7,5% (P2), and 10% (P3) in 100% of the commercial ration given. Broiler chickens were raised in colony battery cages for five weeks of the trial period. The observed variables were cholesterol, triglyceride, HDL, and LDL plasma levels. Data were analyzed using analysis of variance and Duncan's multiple range test. The results showed that the estimated tannin compounds in rubber leaf powder consumed were 0.11%-0.22% and that the feeding treatment significantly decreased (P<0.05) blood cholesterol and triglyceride levels and significantly increased (P<0.05) blood HDL levels. Still, it had no significant effect on the LDL levels of broiler chickens. Based on the study's results, it can be concluded that adding 7.5%-10% rubber leaf flour to commercial rations can be used as a feed additive for reducing blood cholesterol levels in broiler chickens. Keywords: Rubber Leaf Flour, Broiler Chicken, Cholesterol, Triglycerides, HDL, LDL
