Dietary effect of rice milling waste and supplementary enzyme on performance of broiler chicks

Abstract

A four-week study was conducted to determine the effects of feeding rice milling waste (RMW) and supplementary enzyme (Roxazyme G2 ®) on the performance of broiler chicks. One hundred and twenty (120) 7-day old broiler chicks of Anak strain were randomly divided into eight groups of 15 birds each. The groups were randomly assigned to 8 isocaloric (2.85 Mcal of ME/kg) and isonitrogenous (22.00% crude protein) diets in a 4 × 2 factorial arrangement involving a control (0%), three levels (10, 15 and 20%) of RMW and two enzyme levels (0 and 0.02%). Each treatment was replicated three times with five birds per replicate. Results show that feed intake, average daily weight gain, protein efficiency ratio, costs of daily feed intake and feed cost per kg weight gain were significantly (P<0.05) different among the treatment diets. Haematological values such as Haemoglobin concentration (Hb), mean cellular volume (MCH), mean cellular haemoglobin concentration (MCHC) and mean cell volume (MCV) were not significantly (P>0.05) affected by the treatments. Enzyme supplementation resulted in a significant (P<0.05) reduction in feed intake and enhanced significantly (P<0.05), the performance of birds that consumed such enzyme supplemented diets. It was concluded that up to 20% RMW can be included in broiler starter diet without any adverse effect on growth performance of birds. However, the significant increase in feed cost per kg weight gain emanating from the inclusion of enzyme in some of the diets may negate the positive effect that Roxazyme G2 ® enzyme had on growth performance of the broiler chicks.

Control of Avian Coccidiosis: Present and Future Strategies for Natural Alternatives of Therapeutics

“…Fang et al (2012) elaborated the anti-inflammatory and therapeutic results of acid hydrolysed feurloylated oligosacchrides (FO) from rice bran at dose rate of 0.1-100 µg/mL through increased TNF-a, IL-1b, IL-6 and PGE2 production in RAW264.7 macrophages. Ani et al (2013) concluded that feeding rice milling waste (RMW) improved growth rate through increased feed intake in broiler chicks. Rice is also known as an important immunostimulant and therapeutic agent against avian coccidiosis.…”

“…It was also concluded that rice bran derived arabinoxylans have a potent chemotherapeutic effect against metastatic breast cancer. Ani et al (2013) conducted a study to evaluate comparative effects of feeding rice milling waste (RMW) and Roxazyme G2® enzyme on the performance of broiler chicks. Enzyme supplementation significantly reduced feed intake and improved the performance of birds in terms of average daily weight gain, protein efficiency ratio and feed cost.…”

Effects of Dietary Rice Offal Inclusion Level and Enzyme (Natuzyme) Supplementation on the Performance and Nutrient Digestibility of Finisher Broiler Chicken

“…It has been estimated that 70-80% of poultry production inputs is been attributed to feed cost, hence making it imperative that good quality feed be available at reasonable price to make poultry production more profitable [4]. For this to happen, there is need to explore the use of alternative and non-conventional feed ingredients that are cheaper and locally available [5]. One of such alternative feed ingredients is rice offal.…”

The Evaluation of Silica+ Supplementation in Different Type of Diet on Performance, Nutrient Retention and the Economic Value of Broilers Diet

“…Melemahnya efisiensi pakan yang disertai dengan menurunnya pertumbuhan menggambarkan bahwa tidak hanya kandungan serat (insoluble NSP) yang menjadi faktor pembatas penggunaan rice bran dalam ransum broiler pada penelitian ini. Beberapa faktor anti nutrisi lain yang pada umumnya terdapat pada rice bran diantaranya: ketengikan oksidatif dan hidrolitik, kandungan asam fitat dan enzim inhibitor (Gallinger et al, 2004;Ani et al, 2013).…”
