Abstract

The research aims to examine the effect of adding betel leaf flour to goat feed in vitro on partial VFA production and the acetate/propionate ratio. The research material used betel leaf flour, basal feed consisting of ammoniated rice straw and concentrate in a ratio of 40%: 60%. The media used for in vitro experiments was rumen fluid taken from 3 goats immediately after the goats were slaughtered. The research was designed according to a Completely Randomized Design (CRD) with treatments namely the addition of 0%, 5% and 10% betel leaf flour. The parameters observed were the production of acetic, propionic and butiic acids, as well as the ratio of acetic and propionic acids. The results of the study showed that the addition of betel leaves at the level of 0-10% in the feed had a very significant effect (P<0.01) on the production of acetic and propionic acids, while the production of butyric acid and the ratio of acetic and propionic acids had no significant effect (P>0.05) between treatments. Based on the orthogonal polynomial test, increasing the dose of adding betel leaf flour to the feed increased the production of acetic and propionic acids quadrater (P<0.01) with peak points at 6.97% and 7.19% respectively. It was concluded that the addition of betel leaf flour to goat feed based on ammoniated rice straw tested in vitro could increase partial VFA production but did not affect the ratio of acetate and propionate formed. The use of betel leaves as a defaunator to increase VFA production is most optimal at a dose of 7.19%.

Abstract

This study aims to determine the effect of meat of culled laying hens marinated with young papaya fruit. This study used a completely randomized design (CRD) with 4 treatments and 5 replicates. The treatments used in this study were P0 (without marination of young papaya fruit (control)), P1 (extract marination of young papaya with a percentage of 15%), P2 (extract marination of young papaya with a percentage of 30%), P3 (extract marination of young papaya with a percentage of 45%). The material used in this study was chicken breasts with a weight of 100 grams for each treatment. The variables observed in this study were organoleptic tests including aroma, color, and texture. Data obtained from the panelists' assessment were analyzed using Non-parametric analysis (Kruskal Wallis).  The results showed that the highest level of preference for the color variable was in treatment P3 with a value of 4.15, the highest texture was in P3 with a value of 3.6 while the highest aroma was in P0 with a value of 3.5. In conclusion, the meat of retired laying hens marinated with young papaya fruit showed that the best concentration was by giving 45% young papaya fruit extract which gave a significant effect (P <0.05) on color and texture. While for aroma it had no significant impact. Keywords: Aborted Layers, Marinated Young Papaya Fruit (Carica papaya L.), Organoleptic Test.
