Abstract

The aim of this experiment was to determine the effect of level of substitution of Bothriochloa pertusa grass with water spinach on the feeding behavior of kacang goats. As many as 4 kacang goats, ranging in age from 1-1.5 years with an initial body weight of 16,2 – 19,8 kg averaged ± 18 kg were involved in this experiment. This study followed the Latin Square Design (RBSL) 4 x 4 with 4 treatments and 4 periods as replications. The treatments were P0: 60% Bothriochloa pertusa grass + 40% leucaena, P1: 45% Bothriochloa pertusa grass + 40% lamtoro + 15% water spinach, P2 : 30% Bothriochloa pertusa grass + 40% leucaena + 30% water spinach , P3: 15% Bothriochloa pertusa grass + 40% leucaena + 45% water spinach. The measured variables included the frequency and eating time, frequency and ruminating time, and frequency and resting time. The data obtained were analyzed using Analysis of Variance (ANOVA). Replacing Bothriochloa pertusa grass with water spinach is expected to reduce the lenght of eating of kacang goats The results showed that treatment had no significant effect (P>0,05) on the measured parameters. The duration and frequency of feeding ranged from 7.3 to 8.5 hours and 9.75 to 10.12 times per day, duration and frequency of rumination ranged from 6.7 to 7.18 hours and 10.12 hours to 10.50 times per day, and the length and frequency of rest ranged from 8.27 to 9.15 hours, and 16.37 to 18.62 times per day. It was concluded that the substitution of Bothriochloa pertusa grass with water spinach does not affect on the ingestive behavior of kacang goats.

Abstract

The purpose of this study was to determine the effect of the length of biofermentation time of Chromolaena odorata with a source of liquid palm sugar carbon on the physical quality content. The method used in this study is the Complete Randomized Design (RAL) method with 4 treatments and 4 repeats so that there are 16 experimental units. The treatment used is: LB0: biofermentation duration 0 days, LB7: biofermentation duration 7 days, LB14: biofermentation duration 14 days, LB21: as control. The results of variety analysis showed that biofermentation of Chromolaena odorata with liquid palm sugar carbon source had a real effect (P>0.05) on color, aroma, texture, pH and temperature, but did not have a real effect (P<0.01) on the presence of fungi. Based on the results of the study, it can be concluded that the length of biofermentation time of Chromolaena odorata with a source of liquid palm sugar carbon at a length of 14 days gives the best results for color, texture and temperature, the length of 7 days gives the best results for pH and smell while biofermentation with different times gives the same effect for the presence of fungi.

Abstract

This study aims to determine the effect of the duration of wheat bran fermentation on the content of crude fiber, neutral detergent fiber (NDF), and acid detergent fiber (ADF). The design used was the Completely Randomized Design (CRD) method with 4 treatments and 4 replications, resulting in 16 experimental units. The treatments consisted of fermentation durations of 0 days (LF0), 2 days (LF2), 4 days (LF4), and 6 days (LF6). Prior to fermentation, wheat bran was mixed with an inoculum solution at a 1:1 ratio. The inoculum was made from a mixture of 16 liters of clean water, 30 ml of EM4, 100 ml of liquid sugar, and 100 ml of fresh cow feces liquid taken from cows fed with lamtoro and fresh grass. The variables studied in this research were the content of crude fiber, neutral detergent fiber (NDF), and acid detergent fiber (ADF). The data were analyzed using analysis of variance (ANOVA) for CRD where the alpha value was set at 0.5%, and differences between treatments were followed by Duncan's test using SPSS version 25. The results of the statistical analysis showed that the duration of wheat bran fermentation had a very significant effect (P<0.01) in reducing all fiber variables. The total value of crude fiber content decreased from 51.95% (LF0) to 42.86% (LF6), likewise NDF decreased from 36.55% (LF0) to 29.90% (LF6), and ADF content decreased from 13.62% (LF0) to 9.12% (LF6). Based on the results of this study, it can be concluded that the longer fermentation of wheat bran using fresh cow feces liquid as an inoculum is capable of reducing the content of crude fiber, NDF, and ADF with a fermentation duration of 6 days (LF6), obtaining total values of crude fiber content (42.86%), NDF (29.90%), and ADF (9.12%).

Abstract

This study aimed to determine the effect of the duration of wheat bran fermentation on phytate acid content, in vitro dry matter digestibility, and organic matter digestibility. The method used in this study was a Completely Randomized Design (CRD) consisting of 4 treatments and 4 replications, resulting in 16 experimental units. The treatments were as follows: LF0: without fermentation (control), LF2: fermentation for 2 days, LF4: fermentation for 4 days, and LF6: fermentation for 6 days. The mixture of the research material before fermentation was wheat bran mixed with an inoculum solution at a ratio of 1:1. The inoculum was made from a mixture of 15 liters of clean water, 30 ml of EM4, 100 ml of liquid palm sugar, and 100 ml of fresh cow dung fluid taken from cows fed with fresh leucaena leaves and grass. The variables measured in this study were phytate acid content, dry matter digestibility (DMD), and organic matter digestibility (OMD). The results of the statistical analysis showed that the treatments had a very significant effect (P=0.01) on the phytate acid content, dry matter digestibility (DMD), and organic matter digestibility (OMD) of fermented wheat bran. The total phytate acid content value in LF0 was 0.48%, which decreased to 0.28% in LF6, dry matter digestibility in LF0 was 69.75% and increased to 74.98% in LF2, and organic matter digestibility in LF0 was 70.19% and increased to 75.56% in LF6. Based on the research results, it can be concluded that wheat bran with different fermentation durations using fresh cow dung can reduce phytate acid content and increase dry matter digestibility and organic matter digestibility in wheat bran.

Abstract

leaf meal mixture in the basal medium on the utilization of dry matter, crude protein, crude fat, and nutrient conversion in black soldier fly larvae (BSFL). The experiment was designed using a completely randomized design (CRD) with five treatments (0%, 10%, 20%, 30%, and 40% of the Moringa-Leucaena leaf meal mixture) and four replications. The basal medium consisted of 80% rice bran and 20% cornmeal, fermented for seven days before use. A total of 1000 BSFL were introduced into the fermented medium in each experimental unit, and harvesting was conducted on day 14.The results showed that the addition of the Moringa-Leucaena leaf meal mixture significantly increased dry matter utilization (DMU: 0.17–0.33%), crude protein utilization (CPU: 1.21–1.62%), and crude fat utilization (CFU: 4.00–7.00%), while reducing the feed conversion ratio (FCR: 6.23–3.27). The optimal level for all variables was found in the treatment with 40% Moringa-Leucaena leaf meal mixture. In conclusion, the addition of Moringa-Leucaena leaf meal as a protein source in the basal medium can improve nutrient utilization and feed efficiency in black soldier fly larvae.

Abstract

This study aims to determine the effect of the length of biofermentation time of Chromolena odorata with a carbon source of putak flour on physical quality (color, odor / aroma, texture, mold, pH and temperature). The method used is an experimental method with a complete randomized design (RAL) with 4 treatments and 4 repeats so that there are 16 experimental units. The treatment used consisted of Lb21: Biofermentation duration 21 days (as control), Lb14: Biofermentation duration 14 days, Lb7: Biofermentation duration 7 days, and Lb0: Biofermentation duration 0 days. The results of statistical analysis showed that the length of biofermentation time of Chromolaena odorata with the carbon source of putak flour had a very real effect (P<0.01) on color, aroma and temperature but a real effect (P>0.05) on texture, fungal density and pH. From the results of the study, it was concluded that the length of biofermentation time of Chromolaena odorata silage 14 days provides excellent color value and the length of biofermentation time of Chromolaena odorata 7 days which gives excellent odor / aroma and temperature value.

Abstract

This study aims to determine the effect of providing complete feed silage from various types of forage with the addition of concentrate containing ZnSO4 and Zn-Cu isoleucinate on rumen fermentability (pH, VFA, and NH3) in Peanut Goats. The method used is an experimental approach with a Latin square design (RBSL), consisting of 4 treatments in 4 periods as replications, resulting in 16 experimental units. The treatments applied were silage based on Kume grass, Chromolaena odorata, sorghum, and Odot grass, each with 20% concentrate. The results of the analysis showed that the administration of 20% concentrate had no significant effect on pH (P>0.05), but had a very significant effect on VFA and NH3 concentrations (P<0.01). It can be concluded that feeding silage based on these forages does not affect pH, but increases VFA and NH3 concentrations.

Abstract

The aims of this study was to determine the effect of the length of time of Chromolaena odorata biofermentation with putak flour carbon source on methane production, pH, NH3 and Total VFA in-vitro. The main materials used were Chromolaena odorata, putak flour, and rumen fluid.  The method used was an experimental method with a completely randomised design (CRD) pattern consisting of 4 treatments and 4 replications. The treatments were LBf21 = 21 days biofermentation duration (as control); LBf14 = 14 days biofermentation duration; LBf7 = 7 days biofermentation duration; LBf0 = 0 days biofermentation duration. The variables studied were Methane Production, pH, NH3 and VFA in-vitro.  The results of statistical analysis on the variables of methane production, NH3 and total VFA showed that the treatment had no significant effect (P>0.05), while the pH value statistically showed that the treatment had a significant effect (P<0.05) on the length of time of biofermentation of Chromolaena odorata silage. It is concluded that the length of time of the biofermentation process has not been able to increase the production of total VFA, NH3, and reduce methane production but is able to increase the pH value of Chromolaena odorata silage silage from the biofermentation process.

Abstract

This research aims to determine the effect of giving odot grass silage with rice straw as an absorbant on consumption, digestibility and nitrogen retention in goats. This research used a Latin square design (LSD) with 4 treatments and 4 periods as a repeat. The treatment is JP0 = silage 100% odot grass, JP10 = + silage 90% odot grass and rice straw 10%, JP20 = silage 80% odot grass and rice straw 20%, JP 30 = silage 70% odot grass and rice straw 30%. The parameters observed are nitrogen consumption, nitrogen digestibility, and nitrogen retention. The data obtained were analyzed using Analysis of variance. Based on the results of the study, the average Consumption of N (g/h/d) JP0: 12,677 JP10: 10,180 JP20: 9,486 JP30: 10,882. Digestibility average N (%) JP0 : 86,493 JP10: 88,918 JP20: 88,699 JP30: 87,576. Retention average N (g/h/d) JP0: 11,089 JP10: 8,574 JP20: 8,070 JP30: 8,469. Shows that the application of odot grass silage with rice straw as an absorbant has no real effect (P >0.05) on nitrogen consumption, nitrogen digestibility and nitrogen retention. The use of rice straw as an absorbant of up to 30% in the manufacture of odot grass silage did not affect the consumption of dry matter, organic matter and nitrogen and digestibility of dry matter, organic matter, nitrogen and nitrogen retention in goats.
