Effects of Cassava (Manihot Esculenta Crantz) Root Meal in Diets Containing Corn Dried Distillers Grains With Solubles on Production Performance, Egg Quality, and Excreta Noxious Gas Emission in Laying Hens

Abstract

This study was conducted to evaluate effects of cassava (Manihot esculenta Crantz) root meal (CRM) in laying hen diets containing corn dried distiller grains with soluble (DDGS) on production performance, egg quality, and excreta noxious gas emission. Two hundred and forty Hy-Line brown laying hens (40 weeks of age) were randomly divided into 1 of 4 dietary treatments (10 replications with 6 hens per replication) for 6 weeks. The dietary treatments were as follows: 1) corn-based diet (CON); 2) diet containing 10% CRM and 8% DDGS (CRM10); 3) diet containing 20% CRM and 8% DDGS (CRM20); 4) diet containing 30% CRM and 8% DDGS (CRM30). The inclusion of 30% CRM in the diet containing 8% DDGS significantly decreased (p<0.05) average daily feed intake (ADFI), egg production, and feed conversion ratio. Increasing the level of CRM in laying hen diets did not affect (p>0.05) the egg quality with the exception of decreased (p<0.05) egg yolk color when 30% of CRM was included in laying hens diet. CRM20 and CRM30 dietary treatments tended to decrease ammonia emission compared with CON dietary treatment (p=0.08). In conclusion, the results of the current study demonstrated that CRM may be incorporated to a concentration of 20% in laying hen diets containing 8% DDGS without detrimental effects on production performance and egg quality. Furthermore, the addition of 20% and 30% CRM in laying hen diets containing 8% DDGS tended to reduce the excreta ammonia emission.

Krill Meal Enhances Antioxidant Levels and n-3 Fatty Acid Content of Egg Yolk from Laying Hens Fed a Low-Pigment Diet

“…When 7.5% cassava meal was incorporated in the diet, the level of corn was reduced because cassava is documented as a good energy source for poultry. However, Lei et al (2017) indicated that cassava meal could replace up to 30% of corn in the diet of laying hens without any adverse effects on performance.…”

Factors Affecting the Utilisation of Cassava Products for Poultry Feeding [Review]

“…Cassava root or tuberscontributes 50% of mature plant and is the main nutritional food source [15]. Cassava root has 12.56-13.72 MJ/kg metabolisable energy [16,17], 14.5-37 g/kg crude protein, 5.8-28.4 g/kg ether extract, 94-103 g/kg crude fibre, 21.2-68.5 g/kg Ash and 886-948 g/ kg dry matter [8,18,19]. Cassava root has high carbohydrate content (32 to 35% fresh and 80-90% dry matter) [20].Starch is produced from 80% carbohydrates [21] of whichamyl pectin is 83% and amylose is 17% [22].…”

Possibilities of dried distillers' grains with solubles application in animal feed

“…Dry distillers' grains with solubles (DDGS) are a valuable and affordable by-product of the bioethanol industry available in large quantities that can be used as a replacement for traditional feedstuff (Lei et al, 2017;Semenčenko et al, 2014). During the bioethanol production process, a total of 229 kg of DDGS with 90% dry matter content can be obtained, while producing 293 liters of bioethanol per 1000 kg of maize grain (12% moisture and 65% starch, calculated on dry matter) (Chatzifragkou et al, 2015;Liu, 2011;Mojović et al, 2007).…”
