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 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.

Abstract

The purpose of this study was to evaluate the effects of feeding sorghum-Clitoria ternatea-based complete feed silage with additional concentrates containing ZnSO4 and Zn-Cu Isoleucinate at different levels on consumption, crude protein digestibility, and nitrogen retention of Peanut goats. A total of 12 Peanut goats with an average weight of 13.19 kg were used in this study using a Randomized Group Design (RAK) with 4 treatments and 3 replications. Results showed that silage feed with 150 mg ZnSO4/kg BK ration and 2% Zn-Cu Isoleucinate/kg BK concentrate significantly affected crude protein consumption and digestibility, and nitrogen retention. The addition of concentrate up to 30% was the best treatment.

Abstract

The aim of this research was to determine the effect of long fermentation time for rice bran on phytic acid content, dry matter digestibility and organic matter. The method used in this research was an experimental method with a completely randomized plan (CRD) of 5 treatments and 5 replications so that there were 25 experimental units, consisting of LF0: 0 days fermentation time, LF2: 2 days fermentation time, LF4: 2 days fermentation time. long fermentation time 4 days, LF6: long fermentation time 6 days, LF8: long fermentation time 8 days. The parameters taken are phytic acid content, dry matter digestibility (KcBK) and organic matter (KcBO). The results obtained statistically stated that the fermentation time of up to 8 days showed the same results or had a significant effect (P<0.05) on the digestibility of dry matter and organic matter and had no significant effect (P>0.05) on the phytic acid content. The conclusion that can be drawn is that different fermentation times for rice bran can increase the digestibility of dry matter and organic matter in vitro even though the phytic acid content obtained is the same.

Abstract

The purpose of this study was to determine the effect of the addition of liquid palm sugar as a carbon source in the Chromolaena odorata biofermentation process on cellulose, lignin, phytic acid, nitrite and saponin content. This study used a completely randomized design (CRD) with 4 treatments and 4 replicates. The treatments were: LB0 = 0 days of biofermentation, LB7 = 7 days of biofermentation, LB14 = 14 days of biofermentation, and LB21 = 21 days of biofermentation. The variables observed were cellulose, lignin, phytic acid, nitrite and saponin content. The data obtained were analyzed using Analysis of Variance and Duncan's test. The results showed that the length of biofermentation time significantly decreased cellulose content with a range of (23.52-19.26%), lignin (13.75-8.72%), phytic acid (4.03-2.00%), nitrite content (6.60-4.73ppm), and saponin (7.68-5.84%). It was concluded that the length of Chromolaena odorata biofermentation time decreased the content of cellulose, lignin, phytic acid, nitrite content and saponins with varying lengths of biofermentation time, namely the length of biofermentation time of 7 days (LB7) getting a total value of cellulose content (20, 40%), lignin (9.23%), the length of biofermentation time of 14 days get the total value of phytic acid content (2.23%), nitrite (4.86ppm) and the length of biofermentation time of 21 days get the total value of saponin content (5.84%).
