Embodiment 1

[0104] Example 1: NIR model

[0105] NIR models were established for digested samples of pig and poultry feed. The model can be used in conjunction with digestion assays to evaluate the digestibility of feed samples by estimating the amount of residual components in digested samples.

[0106] figure 1 An exemplary scheme of a method of digesting and analyzing a feed sample as described herein is shown. This figure shows that initial feed samples were digested in vitro and the digestate was analyzed for residuals for total energy, protein, phosphorus and sugar content using NIR and wet chemistry.

[0107] Poultry and swine feed samples were digested using a digestion assay similar to in vitro digestion of nutrients. The assay was modified from Boisen S., A multienzyme assay for pigs, Chapter 10, A Model for FeedEvaluation Based on Invitro Digestible Dry Matter and Protein, Invitro Digestion for Pig and Poultry, 1990, M.F.Fuller.

[0108] The digested samples were analyz...

Embodiment 2

[0174] Validation of the porcine residual protein model

[0175] The predictive power of the residual protein model for swine feed digests was validated. The validation method reflects how the method described here was used to analyze feed samples with unknown characteristics.

[0176] A set of swine feed samples were digested as described in Example 1 and scanned by NIR. The protein content of each sample was also characterized using wet chemistry. Divide the samples into a validation set and a model building set. Samples in the model building set were used to build models as described herein. Test the validation set in the model to generate predicted concentrations of residual protein for each sample. The predicted concentration for each sample was compared to the (true) concentration of residual protein in that sample as determined using wet chemistry. The results are shown in Table 1:

[0179] These results show that the model has a hig...

Abstract

The present application provides systems and methods for analyzing animal feeds and for adjusting animal feeds to improve the digestibility of animal feed components. Digestibility of animal feed can be determined by performing in vitro digestion of the feed and analyzing concentrations of residual components in the digested feed by NIR spectroscopy. Animal feed compositions can be adjusted to improve digestibility of components in the feed. The systems and methods of the present application can be used to determine the effect of an additive on the digestibility of feed.

Description

[0001] Cross References to Related Applications [0002] This application was filed as a PCT International Patent Application on February 11, 2014, and claims priority to U.S. Patent Application Serial No. 14 / 109,926, filed December 17, 2013, the disclosure of which is incorporated by reference in its entirety This article. technical field [0003] The present invention relates to systems and methods for conditioning animal feed. In particular, the present application relates to in vitro systems and methods for analyzing the digestibility of nutrients in animal feed. Background technique [0004] Nutrients in animal feed are obtained by the animal through digestion of the feed in the animal's gastrointestinal tract. Digested nutrients are absorbed by the animal and used for energy, growth and development. Most of the undigested nutrients pass through the animal's gut, reducing the nutritional value of the feed. Digestibility of animal feed can be assessed by analyzing re...
