Abstract

Egg chips are not yet common in society; therefore it is necessary to require attention for consumer assessments. Consumer ratings of egg chips indicate that consumers can accept egg chip products. The study aims to determine the effect of adding the types and levels of filler on the organoleptic quality of egg chips. Eighty-one eggs were used in the research. The studies were arranged based on a completely randomized design with a 3 x 3 factorial pattern with 3 replications. The first factor consisted of 3 types of fillers; there are tapioca powder, soybean protein isolate, and porang powder. The second factor was the level of filler (%) 3, 6, and 9 respectively. The parameters measured were egg chips' organoleptic quality (aroma, color, texture, and fondness). The results data indicated that the types and levels of fillers had a highly significant effect (P<0.01) on aroma egg chips. There was an interaction between types and levels of filler on the aroma. There was no significant difference (P>0.05) in color, texture, and fondness for egg chips. Adding the type and level of filler material could improve the organoleptic quality of egg chips. The addition of 9% of tapioca powder can increase the aroma of egg chips. Keywords: Egg powder, egg chips, organoleptic

Abstract

Utilization of unconventional materials such as corn tumpi and dragon fruit peel flour as an alternative feed ingredient for ruminants, especially goats. This study aims to examine the effect of providing complete feed containing corn tumpi with dragon fruit peel flour at different levels on consumption and digestibility of goats. This study used 12 local male goats with ages ranging from 1 to 1.5 years which were randomly assigned to metabolic cages. The study used a Randomized Block Design (RBD) method with 3 treatments and 4 groups. The treatments consisted of P1: Complete feed containing 50% corn tumpi, P2: Complete feed containing 45% corn tumpi and 5% dragon fruit peel flour and P3: Complete feed containing 40% corn tumpi and 10% dragon fruit peel flour. The results showed that the treatment of complete feed containing corn tumpi with dragon fruit peel flour at different levels had a significant effect (P<0.05) on dry matter consumption and organic matter consumption. Dry matter consumption ranged from 296.88 – 461.64 g/h/day, and nitrogen consumption was between 265.74 – 407.72 g/h/day. Treatment of complete feed containing corn tumpi with dragon fruit peel flour at different levels had no significant effect (P>0.05) on dry matter digestibility and organic matter digestibility. Dry matter digestibility ranged from 82.75 – 87.50 %, and organic matter digestibility between 84.5 – 88.75 %. It was concluded that based on estimates of dry matter consumption and organic matter consumption, the use of alternative ingredients for corn tumpi with dragon fruit peel flour up to a level of 10% could be used as a complete mix of feed ingredients for ruminants, especially goats.

Abstract

The aim of this research was to examine the feed rumen fermentation in the rumen of goat fed 4 different diets. This study was designed based on the Latin Square Design which consists of 4 diet treatments with 4 replications in each diet treatment. A total of 4 male goats, with relatively the same weight and age, were randomly assigned to an individual metabolic cage fed with 4 diets. The four diets studied were R1: Elephant grass, R2: Mini elephant grass, R3: Panicum maximum grass and R4: Brachiaria decumbens grass. Each diet was added with 20% of rice bran. The result of this experiment indicated that there was no any significant effect of different diets on the pH values, concentrations of VFA (Volatile fatty acids), and Ammonia (NH3) in the rumen of goat. The pH values in the rumen of goat treated with R1, R2, R3, and R4 were 7.17, 7.12, 7.07, and 7.0, respectively. The concentration of ammonia (mM) in the rumen of goat treated with R1, R2, R3, and R4 were 4.6, 3.3. 4.5, and 4.1, respectively. Whereas the level of VFA (mM) in the rumen of goat treated with R1, R2, R3, and R4 were 40.4, 43.6, 48.7, and 49.9, respectively. There was no any significantly difference (p>0.05) in the characteristic of rumen fermentation between the diet treatment. This might be due to the similarity in the nutrient content of those grasses studied. The characteristic of rumen fermentation was in the range of optimal growth of rumen microbes. It is concluded that those of four grasses studied edible, acceptable and contain a good nutrient as a feed resource for goat. The nutrient content of the grasses studied creates a good rumen environment for optimum feed fermentation in the rumen of goat.

Abstract

Intensification of artificial insemination (AI) in Bali cattle is a government program to increase the population and productivity of local cattle. The objective of this study was to examine the reproductive performance of Bali cows through the AI program in Polewali Mandar Regency, West Sulawesi. The study was conducted in two different locations, i.e. in the low lands (<300mASL) including Wonomulyo and Campalagian Districs, and high lands (>300mASL) including Limboro and Bulo Districts. Data collection was carried out on farmers and inseminators profiles, and cow’s reproductive parameters including service per conception (S/C), conception rate (CR), calving rate (CvR), calving interval (CI) and Calf Mortality (CM). These data were calculated and analyzed descriptively. The cows in this study were raised by farmers in small-scale farm, mostly under 5 heads. The cattle breeding through AI program was carried out by inseminators with over 10 years of experience. In the lowlands, S/C values were 1.26-1.17 and CI were 360 to 366.31 days, respectively. Bali cows that were inseminated using Bali bull semen had a CvR of 75.69% which were higher than those using Simmental bull semen (CvR 49.69%;). While in the highlands, Bali cows that were inseminated with Bali bull semen tended to have higher S/C (1.30) and CI (356.95 days) values but had CvR of 61.00% and CR 77.00% which was also higher than that of Simmental bull semen (S/C 1,50; CI 412,86 days; CvR 50.00%; CR 66.67%). The high S/C in the highlands (1.50) is due to location constraints or the distance between the livestock and the inseminator's residence which is quite far, so it takes time to carry out AI services and is one of the factors that can cause the provision of AI services for female cows in heat is not optimal. In the highlands, most of the cattle are grazed in the grazing areas, making it difficult for breeders to detect estrus. In general, Bali cattle produced by AI in the low lands of Polewali Mandar district tended to have better reproductive performance than those in the high lands. The S/C in the low lands (1.26 and 1.17) is lower than that in the high lands (1.3 and 1.5). Keywords: AI, Bali cows, lower land, high land reproductive performance

Abstract

Layer eggs are low cost and highly nutritious, but they are perishable. Therefore, it is important applying preservation for prolong its shelf life. Preservation by using natural agent such as belimbing wuluh (Averrhoa bilimbi L) leaf (BWL) extract for food safety and consumer health is ratioable. This study aimed to evaluate the immersion of layer eggs in an aqueous extract of BWL on the pH value and total microbial eggs. The treatments employed were eggs without soaking (P0), eggs soaked in aquadest (P1), eggs soaked in solution of BWL leaf extract (SBWLE) 15% (P2), eggs soaked in SBWLE 30% (P3), and eggs soaked in SBWLE 45% (P4). Soaking was carried out for 24 hours with the proportion of egg: water SBWLE was 1:13. The extraction process was carried out by boiling the BWL for 10 minutes at a temperature of 85 ºC. The boiled water is filtered and the results were used for treatment. The data were analyzed by ANOVA and he significant effect (P <0.05) of treatments were tested by a post hoc Duncan's Multiple Range Test (DMRT). The results showed that eggs soaked in SBWLE had lower pH and total microbes than eggs without soaking and eggs soaked in aquadest. The higher concentration of SBWLE, the decreasing pH and total microbes in eggs. The conclusion was that the use of SBWLE 15-45% (w/v) was able to suppress egg microbial growth and prevent an increase in egg pH. Keywords: Averhoa bilimbi, egg quality, microbes, pH

Abstract

The Indonesian government's efforts to support food and beverage products that must be halal-certified by 2024 are by implementing a halal product guarantee system in the industry. One of the industries that must implement halal guarantees is poultry slaughterhouses. One of the criteria for a halal assurance system in a poultry slaughterhouse is the role of human resources.  This study aims to analyze the knowledge of human resources in Poultry Slaughterhouses. Application of knowledge about commitment and responsibility consists of halal criteria, human resource development, top management responsibilities, and training of halal staff. The object of research is poultry slaughterhouses that have implemented SNI halal standards and have not implemented SNI halal standards. The study used 52 samples using 2 technic, field studies consisting of observation, interview, questionnaire, documentation, and literature study techniques. Assessment of respondents' knowledge using the order of assessment (Likert scale). The knowledge of workers in an SNI halal standards poultry slaughterhouse regarding commitment and responsibility was in the very high category. However, poultry slaughterhouses do non-SNI halal standards have a very low category. Keywords: poultry slaughterhouses, knowledge, halal

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
