Abstract

BACKGROUND AND OBJECTIVES Native chickens are local poultry with high economic value; however, their productivity remains relatively low, making nutritional improvement particularly from protein sources essential. Trash fish or discarded fish or rucah fish meal has potential as an alternative feed ingredient due to its abundant availability, lower cost, and high protein content. Its utilization may reduce production costs without compromising feed nutritional quality. This study aimed to evaluate the effect of rucah fish meal inclusion in the diet on the digestive organ weights of native chickens. METHODS The experiment was conducted at the Livestock and Forage Cultivation Laboratory, Faculty of Animal Science, Universitas Jambi, using 200 native chickens. A completely randomized design with five dietary treatments and four replications was applied. The treatments consisted of different inclusion levels of rucah fish meal: P0 = 12%, P1 = 14%, P2 = 16%, P3 = 18%, and P4 = 20%, with four replications per treatment. The observed parameters included feed intake, slaughter weight, relative weight of the gizzard, relative weight of the pancreas, and relative weight of the liver. Data were analyzed using analysis of variance (ANOVA), and parameters showing significant effects were further analyzed using Duncan’s multiple range test. FINDINGS The results indicated that the inclusion of rucah fish meal up to 20% in the diet had no significant effect on feed intake, slaughter weight, relative gizzard weight, relative pancreas weight, or relative liver weight of native chickens. CONCLUSION Rucah fish meal can be included in native chicken diets at levels of up to 20% without adversely affecting the performance of digestive organs as reflected by organ weights

Abstract

BACKGROUND AND OBJECTIVES Local chicken production has significant economic potential; however, its development is constrained by low productivity and inadequate feed quality. Native chicken farming plays an important role in supporting the livelihoods of small-scale farmers, yet productivity remains limited due to dependence on conventional feed ingredients such as rice bran, whose availability and quality are often inconsistent. The utilization of agricultural by-products as alternative feed ingredients represents an innovative approach to improving efficiency and sustainability in native chicken production systems. Corncob is an abundant agricultural residue, but its utilization is limited by high crude fiber content and low nutrient digestibility. Fermentation using Effective Microorganisms (EM4) has the potential to enhance the nutritional quality of corncobs, making them more suitable for use as a feed ingredient. This study aimed to evaluate the use of EM4-fermented corncob meal as a substitute for rice bran in native chicken diets and to assess its effects on feed intake, slaughter weight, carcass weight, and carcass percentage. The findings of this study are expected to contribute scientific insights into the development of sustainable, agricultural waste-based alternative feeds that are practical and applicable for small-scale native chicken farming systems. METHODS The study was conducted at the Livestock Production and Forage Laboratory, Faculty of Animal Science, University of Jambi, for a period of eight weeks using 200 day-old native chickens. The experiment employed a Completely Randomized Design (CRD) with five dietary treatments and four replications. The treatments consisted of different inclusion levels of fermented corncob meal (FCM) in the diet, namely P0 = 0%, P1 = 4%, P2 = 8%, P3 = 12%, and P4 = 16%. The observed parameters included feed intake, slaughter weight, absolute carcass weight, and relative carcass weight. Data were analyzed using analysis of variance (ANOVA), and when a significant effect was detected (P < 0.05), Duncan’s Multiple Range Test was applied for mean comparison. FINDINGS The results of this study indicate that corncob meal fermented using EM4 can be utilized as a substitute for rice bran in native chicken diets. The inclusion of this feed ingredient allows normal feed intake to be maintained and is able to sustain slaughter weight and carcass weight of native chickens. CONCLUSION It can be concluded that fermented corncob meal can be included at levels up to 16% in native chicken diets without adversely affecting production performance.
