Abstract

This study was conducted to evaluate metabolizable energy (ME) and amino acid availability of 30 corns from different sources, and to explore new methods for determining the nutritive values of feeds suitable for laying hens. A total of 240 Lohmann laying hens with an average body weight of (1.60±0.10) kg and 90% laying rate were randomly divided into 30 groups by single-factor completely random design. Each group had 8 replicates and 1 laying hen in each replicate. ME and amino acid availability of 30 corns from different sources were investigated by the trained feeding combined with a total collection of excreta, and then the near infrared spectroscopy (NIRS) prediction models of corn ME and amino acid availability were established by Fourier NIRS analysis technique on the basis of determining the ME and amino acid availability of 30 corns from different sources. The result showed as follows: 1) the laying rate reduced to 76.77% from 90.00%, and the average values of 30 corns of egg weight, albumen height, yolk color, Haugh unit, egg shell strength, egg shell thickness and yolk relative weight were 76.77%, 51.17 g, 7.06 mm, 8.08, 84.62, 3.80 kgf, 31.14×10-2mm and 28.15%, respectively, after laying hens fed 30 experimental diets including 89% corn. 2) The ME range of 30 corns from different sources was 11.37 to 16.91 MJ/kg, with average value of 15.26 MJ/kg. The ranges of total amino acid availability and total essential amino acid availability of 30 corns from different sources were 82.06% to 93.23% and 82.37% to 92.97%, with average values of 87.47% and 86.70%, respectively. The average values of 30 corns of valine, isoleucine leucine, phenylalanine, lysine, histidine, arginine and threonine availability were 91.59%, 74.52%, 88.14%, 93.13%, 77.93%, 86.06%, 86.78% and 95.42%, respectively. 3) Rcal2, Rcv2, Rval2 and root-mean-square error of prediction (RMSEP) of NIRS prediction model for corn ME were 0.99, 0.94, 0.95, 0.13 MJ/kg. The ranges of Rcal2, Rcv2, Rval2 and RMSEP of NIRS prediction models for corn amino acid availability were 0.91 to 0.99, 0.81 to 0.94, 0.79 to 0.97, and 0.10% to 1.66%. These results indicate as follows: 1) the method of the trained feeding combined with a total collection of excreta do not cause bigger effects on laying rate and egg quality when evaluating ME and amino acid availability of corn for laying hens; 2) there are variations of ME and amino acid availability between corns from different sources; 3) the NIRS prediction models of corn ME and amino acid availability are established according to the values of corn ME and amino acid availability in laying hens.
