Abstract

The purpose of this research was to find out the effects of liquid turmeric extract (LTE) supplementation as a phytobiotic on carcass production and chemical quality of broiler chicken meat. The research is conducted with a directional pattern completely randomized design. Eighty-four broiler chickens were raised from day old (DOC) to 42 days old chick. From DOC to 14 days old chicks were fed with commercial feed (ME 3,100 kcal/kg; CP 22%; Ca 1%; P 0.75%). During 15-21 days of age given a commercial feed mixture and basal feed (ME 3,201.77 kcal/kg; CP 20.21%; Ca 0.90%; and P 0.43%). At 22-42 days old given treatments. Seven treatments were replicated 3 times consisted of 4 broiler chickens for each replication. The treatments were positive control (P1), negative control (P2), water + LTE 2% (P3), water + LTE 4% (P4), water + LTE 6% (P5), water + LTE 8% (P6), and water + LTE 10% (P7). The results showed that LTE 10% significantly decreased (P<0.05) on the slaughter weight and 8% until 10% dossage had a significant decrease (P<0.05) on the meat water content. However, it did not show a significant influence (P>0.05) on the carcass weight, carcass percentage, meat protein and fat content.

Abstract

This study aimed to evaluate the morphological and genetic diversity among five cultivars of Napier grass (Pennisetum purpureum) grown in Indonesia: ‘Gama Umami’, ‘Pakchong’, ‘Odot’, ‘Purple’, and ‘Local’. A total of 20 plants per cultivar were planted in a completely randomized design with morphological parameters, nutrient content, biomass production, and molecular analysis assessed at a cutting age of 90 days. The morphological analysis revealed significant differences (p<0.05) in plant height, leaf length, and the number of tillers across the cultivars. Qualitative analysis revealed differences in leaf color and growth habits. ‘Gama Umami’ cultivar showed the highest biomass yield, with significantly (p<0.05) higher crude protein and dry matter content than the other cultivars. Random amplified polymorphic DNA (RAPD) analysis using nine primers on the five Napier grass cultivars demonstrated diverse band patterns, resulting in a percentage of polymorphic bands (PBP) ranging from 60% to 100%. The dendrogram derived from the RAPD data clustered the cultivars into two main groups, with ‘Gama Umami’ and ‘Local’ showing a high similarity coefficient of 0.73, while ‘Purple’ and ‘Pakchong’ formed a distinct sub-cluster with a similarity coefficient of 0.66, and ‘Odot’ exhibited a similarity coefficient of 0.58 with the ‘Purple’ and ‘Pakchong’ sub-cluster. This study revealed significant genetic and morphological diversity among five Napier grass cultivars, with 'Gama Umami' demonstrating superior morphological traits, nutrient content, and biomass production. These findings highlight the potential of integrating molecular and morphological analyses to support breeding programs for improving forage quality and productivity.

Abstract

This study aimed to investigate the effect of the biological and chemical additives on fermentation characteristics, aerobic stability, and ruminal digestibility of high-moisture sorghum silage. A mixture of Lactiplantibacillus plantarum FNCC 0020 (LP) and Limosilactobacillus fermentum BN21 (LF) was used as a biological additive and potassium sorbate as a chemical additive. At the milk ripening stage (26.8% of DM), sorghum was harvested, chopped to 3-5 cm length, and ensiled into 20 L silo (5 kg) for 100 days. Subsequently, various additives were added, including a control group without additives (CON), LF + LP with a ratio of 1:1 at 1 x 105 cfu/g fresh weight (INO), potassium sorbate at 1 g/kg fresh weight (PS), and INO + PS (MIX). Each treatment used 5 silos as replication. The results showed that INO silage had the lowest (p<0.05) pH with the highest (p<0.05) contents of lactate and acetate, as well as lactic acid bacteria (LAB) count. PS silage produced the minimum contents of lactate and acetate but had lower yeast compared to CON silage. MIX silage had lower (p<0.05) lactate and acetate contents than CON silage, with a similar effect on yeast inhibition to PS silage. Furthermore, PS and MIX silages had higher (p<0.05) aerobic stability and in vitro digestibility of dry matter and organic matter than CON and INO. These results showed that combining biological and chemical additives was more effective in improving fermentation, aerobic stability, and ruminal digestibility of high-moisture sorghum silage.
