Abstract

Coastal areas are potential land for the cultivation of feed crops to support the availability of livestock forage. Indigofera zollingerianaplants have a high tolerance to salinity stress. Gamma irradiation technology, which can change the genetic structure of plants, is expected to increase plant tolerance. This study was conducted to determine the morphological response of Indigofera zollingeriana Mutant, two plants irradiated with gamma rays in coastal areas. This study used a complete randomized design (CRD) method with ten treatments and six replications. The treatments consisted of P0 (control/without irradiation); P1 (Indigofera M2 50 Gy); P2 (Indigofera M2 100 Gy); P3 (Indigofera M2 150 Gy); P4 (Indigofera M2 200 Gy); P5 (without irradiation + salinity stress); P6 (Indigofera M2 50 Gy + salinity stress); P7 (Indigofera M2 100 Gy + salinity stress); P8 (Indigofera M2 150 Gy + salinity stress); and P9 (Indigofera M2 200 Gy + salinity stress). The analysis of variance showed that different doses of gamma irradiation and salinity stress had a significant effect (P<0.05) on stem diameter and number of flowers of Indigofera zollingeriana plants. Irradiation dose of 150 Gy with salinity stress during seedling can grow higher leaves when planted in coastal areas. Keywords: Salinity Stress, Indigofera zollingeriana, Gamma Irradiation

Abstract

Coastal areas have great potential to be developed. One of the good sectors developed in coastal areas is livestock, but the obstacle to the development of livestock in coastal areas is saline land conditions that can affect the process of plant growth. Indigofera zollingeriana is a plant that is tolerant to various types of environmental stress, one of which is salinity stress. Induced mutation is currently the most effective breeding method for plant genetic improvement. One example of induced mutation treatment is gamma irradiation. This study used a complete randomized design method with ten treatments and six replicates. The treatments consisted of P0 (Control/Without irradiation); P1 (50 Gy gamma irradiation); P2 (100 Gy gamma irradiation); P3 (150 Gy gamma irradiation); P4 (200 Gy gamma irradiation); P5 (Irradiation was given salinity stress); P6 (50 Gy gamma irradiation and salinity stress); P7 (100 Gy gamma irradiation and salinity stress); P8 (150 Gy gamma irradiation and salinity stress); and P9 (200 Gy gamma irradiation and salinity stress). The results of the analysis of variance showed that the treatment of gamma irradiation dose and salinity stress had a significant effect (P<0.05) on the total weight, leaf weight, and leaf production of Indigofera but no significant effect (P>0.05) on stem weight and production.

Abstract

This study aimed to determine forage availability on pastures by analyzing pastures' forage quality and evaluating pastures' biodiversity in Tanete Riaja District, Barru Regency. The results of this study indicated that the botanical composition (BC) in the Tanete Riaja District was shallow because weeds still dominate the pasture in this area by 60%. The biodiversity richness index (BRI) in the pasture of Tanete Riaja District was found in grass species with a margalef index (MI) of 3.09 and in legume species with an MI of 1.21. In contrast, the grass species' diversity index value (DI) was 0.29 Shannon-Weiner index (SWI), and the legume species was 0.36 SWI. The value DI on grass and legume species was classified in the low category. At the research location, there was 0.22 tons/ha of total forage production, while forage livestock could eat 0.15 tons/ha. The results obtained in this study indicated that the carrying capacity or pasture capacity of the natural pasture (NF) area was 0.06 UT/Ha, which was classified as heavy pasture. The results of this study indicated that the percentage of pasture forage in Tanete Riaja, Barru Regency, was dominated by weeds at 37.61%, grass at 48.35%, and legumes at 14.04%. The CC of the pasture area was 0.4 ST / Ha / Year, which is classified as heavy pasture. Keywords: Carrying Capacity, Rumination, Forage, Biodiversity, Grass

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.

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

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
