Abstract

Vegetable waste is a part of vegetables or vegetables that are discarded. This vegetable market wastes are perishable, voluminous (bulky) and the availability was fluctuated so the processing technology is needed to make this vegetable waste become durable, easy to be stored and could be given to the animal. To solve this problem, vegetable waste could be formed into a wafer. The objective of this experiment was to determine the physical characteristic and palatability of vegetable market waste after formed into a wafer. The experimental design used in this research was Completely Randomized Design with 5 treatments and 4 replicates. The treatments were the composition of raw materials used: 100% corn husk  (R1); 75% corn husk  +25% mungbean waste (R2); 50% corn husk  + 25% mungbean waste + 25% cauliflower leaf  (R3); 25%  corn husk +50% mungbean waste + 25% cauliflower leaf  (R4); 25% corn husk  + 25% mungbean waste  +50%  cauliflower leaf (R5).  Variables measured were water activity, water absorption, density and palatability. The results of this research indicated that treatments significantly affected water activity (P<0.08) and wafer palatability (P<0.05). The highly significant difference in water absorption and wafer density (P<0.01) were found among treatments. Based on physical characteristic, R1 had the highest water absorption.  R5 had the lowest water activity, whereas R3 had the highest wafer density. Wafer of R4 was the most palatable for the experimental sheep compare to other treatments.

Abstract

This research was aimed to study the physical characteristic and palatability of wafer complete ration based on sugar cane sprout and bagasse. Physical characteristic measured were water content, water activity and density. Data of physical characteristics were analyzed using Completely Randomize Design, with four treatments and three replications. Analysis data of palatabity test used were T-test method i.e., rations of R0 vs R1 R2 R3, ration of R1 vs R2, ration of R0 vs R3, ration of R3 vs R2. The treatment was wafer complete ration with different fiber source, i.e. R0 = 80% concentrate + 20% field grass; R1 = concentrate 80% + 20% bagasse; R2 = concentrate 80% + sugar cane sprout 10% + bagasse 10%; R3 = concentrate 80% + 20% sugar cane sprout. The data were analyzed using ANOVA and continued with Contrast Orthogonal Test. The result of this research showed that the wafer complete ration that contains sugar cane sprout had better physical characteristics. Palatability of wafer complete ration containing field grass and sugar cane sprout was more preferred than that containing combination of bagasse and sugar cane sprout. The average consumption of wafer complete ration on FH’s calf containing 20% of field grass was ranged at 44–48%, ration containing 20% of bagasse was at 6–10%, ration containing 10% of sugar cane sprout and 10% bagasse was at 13–16% and ration containing 20% of sugar cane sprout was at 30–33%.

Abstract

Fibrous feeds vary in their physical properties. The experiment aimed to clarify the effect of physical properties of fibrous component in rations on feed intake and nutrient digestibility in goats. Rations were composed of 50% fibrous feed and 50% concentrate. The fibrous feed as treatments were as follows: napier grass (RG), rice straw (JP), cocoa pod (KC), mixed rice straw and coffee husk (JK), mixed napier grass, rice straw, coffee husk, and cocoa pod (CP). Rations were offered to four groups of 20 Etawah-grade goats weighing of 13.50±2.14 kg in a randomized block design. Physical properties of the fibrous components of ration and faeces, nutrients intake and digestibility and daily life weight gain were evaluated. Analysis of variance and correlation were applied to analyze data. Dry matter intake varied from 298-440 g/day. Goats offered KC ration had the highest intake. Low feed intake was associated with the low density of the fibrous component. Dietary fat digestibility decreased when the fibrous feed component had low capacity of oil adsorption. Young goats had life weight gain of 50-136 g/day, TDN requirement for maintenance and 50 g daily gain of 63.4 g and 131 g TDN, respectively. The results indicated that physical properties of fibrous component in the rations influenced dry matter intake and nutrients digestibility in growing goats.

Abstract

Fibrous agricultural by-products are the component of most rations for ruminant raised intensively. Slow rate and low digestibility of the fibrous feed may limit mineral bioavailability. Present experiment aimed to clarify the influence of fibrous feed component in ration on the status of Ca, Mg and Zn in growing goats. Twenty of female Etawah-grade goats weighing of 13.5±2.14 kg were grouped and allocated into five treatments in a randomized block design. Rations composed of 50% fibrous feed and 50% concentrate. The fibrous feed component as treatments were: RG = napier grass, JP = rice straw, KC = cacao pod, JK = mixed rice straw and coffee husk, and CP = mixed rice straw, napier grass, coffee husk and cacao pod. Rations were offered at 3% of live weight. The result showed that fibrous feed influenced Ca, Mg, and Zn intake, Ca and Mg absorption, and Ca, Mg and Zn plasma of growing goats. Intake, absorption and plasma Ca, Mg, and Zn had positive correlation with dry mater intake. Absorption of Ca and Zn had positive correlations with crude fiber digestibility. Supplementation of Ca, Mg and Zn was necessary when the fibrous feed was included at the level of 50% in the ration of growing goats, but the supplement level varied according to the type of the fibrous feed.

Abstract

Sugar cane top and bagasse represent agricultural by product which is potential as feed. This research was aimed to study of physical characteristics of wafer complete ration containing sugar cane top and bagasse during storage for six weeks. The treatments were alocated in completely randomized factorial design. The treatments as factor A were R0=80% concentrate + 20% native grass; R1=concentrate 80% + 20% bagasse; R2=concentrate 80% + sugar cane top 10% + bagasse 10%; R3=concentrate 80% + 20% sugar cane top. Factor B was storage period i.e., B1=0 week; B2=2 weeks; B3=4 weeks; B4=6 weeks. The result showed that the wafer complete ration contained natural grass, sugar cane top and bagasse did not affect the specific density and water activity, but the water content was the highest (P < 0.01) in ration containing natural grasses. Storage for six weeks affected (P < 0.01) water content, density and specific density, but did not affect water activity. Wafer complete ration palatability containing grass and sugar cane top was more preferred than sugar cane top combined with bagasse or bagasse without combination.

Abstract

Prill fat is a by-product of cooking oil production that can be utilized as a fat source in animal feed. The prill fat’s fine granular form and difficulty in achieving homogeneity with other materials pose challenges in its utilization. Processing prill fat into supplement wafers can be an alternative for its use, with careful consideration of its melting point. This study aims to optimize the production process of supplement wafers containing prill fat using response surface methodology (RSM) and to evaluate the changes in quality during storage. The research stages include optimizing the production process with temperature and heating time as factors, and the responses tested are production efficiency, moisture content (MC), and wafer durability index (WDI). The optimal temperature and heating time identified were 50°C for 1 minute, yielding a production efficiency of 95.2%, a moisture content of 5.6%, and a WDI of 95%, with the validation results showing a confidence level of 95%. It can be concluded that a temperature of 50°C with a heating time of 1 minute can be applied to produce supplement wafers containing prill fat. Keywords: production optimizing, prill fat, response surface methodology, wafer supplements
