Energy Metabolism and Corn Rations Commercial Broiler Chickens on Broiler Rejected

Abstract

One of the information needed by farmers is information about nutrition ration poultry in accordance with the Indonesian National Standard (SNI). This study aims to determine the value of energy metabolism in commercial chicken rations. Determination of energy metabolism was conducted by Farrel in which chickens were fed like a chicken eating chicken feed itself and previously fasted for 24 hours and still be drinking. The ration of treatment used is feed corn, feed rations BR1 and BR2. Chickens were given time for 2 hours to eat the feed later in the fasting. After fasting rationing and the chicken will issue feces, to prevent the evaporation of nitrogen in the feces spraying by the use of H2SO4 concentration 0,01%. Chicken feces then dried and analyzed by the laboratory using a bomb calorimeter. The data in the analysis of variance (ANOVA) and Duncan test. Corn research results show that the energy metabolism in the feed ration obtained BR1 3.048 kcal/kg and BR2 3.237 kcal/kg. The result can be concluded that the value is in compliance with EM EM minimum value required in SNI minimum of 2.900 kcal / kg with a value of EM listed on the label.Keywords: Energy Metabolism, Commercial feed, Corn

Analysis of Nutrient Digestibility, Hematological Status, and Blood Malondialdehyde Levels in Broiler Chickens Given a Combination of Cassava Tuber and Indigofera zollingeriana Leaves Flour as a Source of Energy in the Ration

“…One of the constituent of the organic matter is carbohydrates which are the most dominant in corn feed ingredients and the combination of CCI. According to Wahyudi et al (2017) corn contains metabolic energy of 3350 Kcal/kg and cassava tubers have metabolic energy of 3519 Kcal/kg (Abdlebasit et al, 2021).…”

“…The metabolic energy content of maize and cassava tubers is almost the same. According to Wahyudi et al (2017) that corn contains metabolic energy of 3350 Kcal/kg, and cassava tubers have metabolic energy of 3519 Kcal/kg (Abdlebasit et al, 2021). Cassava can be used as an energy source to replace corn up to 50% without affecting growth performance of broiler chicken (Chang'a et al, 2020).…”
