Abstract

This study aims to compare the sensory or organoleptic, hedonic and microbiological qualities of beef sausages coated using edible film made from chicken feet skin and added with kaffir lime leaf extract at 0%, 0.5% and 1%. The variables observed were color, aroma, texture, taste and aftertaste. The research was carried out in July 2023 in the laboratory of the Boyolali Veterinary Public Health Service Center and tested on panelists at Boyolali University. Organoleptic and hedonic tests in this study used a completely randomized design with 3 treatments and 25 replications. This treatment consists of P1 = sausage coated with edible film with the addition of 0% kaffir lime leaf extract, P2 = 0.5% kaffir lime leaf extract, and P3 = addition of 1% kaffir lime leaf extract. The results of the ANOVA sensory test showed that the addition of kaffir lime leaf extract to the edible film used to wrap beef sausages did not have a real effect on changes in color and texture, but did have a real effect on changes in aroma and taste. In the liking test, only the Aftertaste test showed a real effect, while the color test, aroma test, texture test and taste test did not show a real effect. Testing the number of microbes through the Total Plate Count (TPC) test showed that the addition of 0.5% lime leaf extract was able to maintain the quality of beef sausages until the 6th day of room temperature storage.

Abstract

The male chicken is the result of laying hens that are male, therefore it is called a male. Broilers are usually harvested when they are two or three months old. In terms of structure, roosters are usually smaller than other types of chickens and have a pure white color. Laying hens of the male type are a by-product of the production of breeding and hatching of laying hens. Laying cocks are considered to have the ability to produce meat. The lighting program is one that is very influential in achieving peak production in relation to uniformity of sexual maturity. The purpose of feeding in the grower phase is to encourage or stimulate the chickens to grow faster, not just grow. So that the development of hereditary organs becomes optimal and supports further sustainable growth.

Abstract

Sausage is a product made from minced meat and then mashed and seasoned, put in artificial packaging, with or without cooking.) due to both oxidative and microbiological damage. Chicken feet are a by-product of chicken slaughterhouses (RPA) whose use is limited because they contain a lot of bones and a little meat, but have a high skin content. The chicken leg consists of several parts such as bone, skin, muscle and collagen. Chicken claw contains collagen of 22.94%. In this study there were 7 stages, namely making gelatin, making kaffir lime oil, making samples, dividing samples, organoleptic tests, hedonic tests, and data analysis. The results of this test indicate that beef sausages coated with edible film with the addition of kaffir lime leaf extract are declared fit for consumption. Because this value is still below the total microbial standard according to SNI (1x106 CFU/g), so beef sausage is still suitable for consumption.

Abstract

The study aimed to determine the development of the small intestine and the growth of super native chickens given synbiotics in the feed with reduced protein content. The research was conducted from June to August 2023. The research design used was a completely randomised design (CRD) with 4 treatments and 5 replicates, each treatment unit contained 10 super native chickens. The synbiotic consists of fermented snail as probiotic and groundnut shell extract as prebiotic. Feed using selfmix with reduced protein content. Synbiotic supplementation in feed consisted of P0 (control), P1 (5 ml/kg), P2 (10 ml/kg), P3 (15 ml/kg). The parameters observed were the weight and length of the small intestine including duodenum, jejenum, and ileum, as well as the final body weight. Data from the study were analysed using Analysis of Variance (ANOVA), if there was an effect of treatment (P < 0.05) followed by honest real difference test. The results showed that the treatment had a significant effect (P <0.05) on duodenum weight and final body weight but had no effect (P>0.05) on jejenum, ileum, or duodenum, jejenum, and ileum length. The conclusion of the study is that synbiotics can increase duodenal weight at the level of 10 ml/kg and final body weight at the level of 5 ml/kg can compensate for the control treatment. Keywords: super native chickens, synbiotics, small intestine, final body weight
