The identification of potential novel feed ingredients requires quick and effective analytical techniques to assess their composition and functionality. This chapter provides a practical guide to routine and standard methods to detect the main traits of interest in animal feed ingredients and additives. It discusses techniques to evaluate feed nutritional value, including chemical composition and nutrient digestibility. The chapter reviews different in vitro methods for feed evaluation systems as well as assessment of nutrient molecular structure. The chapter also discusses analysis of feed bioactive compounds and their functionality. The chapter concludes with a case study on seaweeds as a potential novel feed for livestock.

AbstractIn vitro techniques are widely used to predict the nutritive value of foods for farm animals. However, food evaluation systems are moving towards systems based on nutrient flows rather than on energy or protein. Nutrients are supplied via the digestive tract and presently available in vitro methods are inadequate to simulate the complicated and non-steady-state processes in this tract. This is partly due the lack of adequate in vivo reference values and partly due to a too-high degree of standardization and simplification. Future developments should therefore aim to develop in vitro systems which closely monitor the dynamics of the digestive processes. Adequate interpretation of the results may require sophisticated mathematical models.

This study aims to sup determine the utilization of water spinach as a substitute for forage sources, digestibility, and feed degradation. Klaten Regency is one of the producers of water spinach that has the potential to be developed as the center for producing the largest water spinach at the regional level and has a role as one of supporting the needs of ruminant animal feed at regional and regional levels during the dry season. The method used is a survey, sampling technique with stratified random sampling. The conclusion of the results of this study is the total supply of the use of water spinach reached the level of 20% resulting in higher total gas production, although it did not show a significant difference in VFA digestibility and production in vitro compared to the control. Feed digestibility increased with the addition of water spinach in a feed with a productivity average of 2.05 tons/ha of 3,947 ha of land area. The scheme (chain) of the supply of dried water spinach straw material is 41.25% for privately owned ruminants, and 58.75% is sold to middlemen by being sold to farmers outside the Klaten Regency area.

 The challenges for the feed analysis sector will be to ensure feed quality and safety. Innovative strategies need to be implemented to authenticate feed and feed ingredients and to check that they fulfill all labelling obligations. This chapter focusses on the authentication of feed by different but complementary analytical techniques as microscopy, vibrational spectroscopy, genomics and proteomics. For each technique, trends are presented and, in addition, some combinations of technologies are shown in order to find solutions for complex situations. Moreover, with the explosion of data provided by the different technologies, Data Science is gaining importance as well as the interest for fast, mobile and greener technologies.

Malaysia has begun to locally mass-cultivate grain corn to reduce import dependency for animal feed industries. Since the Malaysian tropical climate constantly exposes grain corn to fungal colonization and mycotoxin production by mycotoxigenic species, it is, therefore, important to investigate the presence of fungal species, especially the mycotoxigenic strains in the Malaysian grain corn agroecosystem. In the present work, corn kernel, tassel, plant debris, and soil were collected from two pioneer grain corn farms (Kampong Dadong, KD; Rhu Tapai, RT), and morphological and molecular identifications were conducted. A total of 131 fungal isolates from 30 fungal species were recovered. Both KD and RT yielded log 4.7–6.7 CFU/g total fungal loads. Fusarium verticillioides was predominant in both farms, followed by the phytopathogenic Lasiodiplodia theobromae and the mycotoxigenic Aspergillus flavus, A. niger, F. incarnatum, and F. proliferatum. Mycotoxin analyses by high-performance liquid chromatography revealed that among 30 mycotoxigenic isolates tested for aflatoxins, deoxynivalenol, fumonisins, HT-2, T-2, ochratoxins A, and zearalenone, approximately 25 of the isolates could produce at least one mycotoxin in vitro. The present work serves as a baseline for more comprehensive research to better predict and control fungal contamination and the subsequent mycotoxin accumulation in Malaysian grain corn agroecosystems.

Physiological Value

Many types of feed ingredients are used to provide energy and nutrients to meet the nutritional requirements of swine. However, the analytical methods and measures used to determine the true nutritional and physiological (“nutri-physiological”) value of feed ingredients affect the accuracy of predicting and achieving desired animal responses. Some chemical characteristics of feed ingredients are detrimental to pig health and performance, while functional components in other ingredients provide beneficial health effects beyond their nutritional value when included in complete swine diets. Traditional analytical procedures and measures are useful for determining energy and nutrient digestibility of feed ingredients, but do not adequately assess their true physiological or biological value. Prediction equations, along with ex vivo and in vitro methods, provide some benefits for assessing the nutri-physiological value of feed ingredients compared with in vivo determinations, but they also have some limitations. Determining the digestion kinetics of the different chemical components of feed ingredients, understanding how circadian rhythms affect feeding behavior and the gastrointestinal microbiome of pigs, and accounting for the functional properties of many feed ingredients in diet formulation are the emerging innovations that will facilitate improvements in precision swine nutrition and environmental sustainability in global pork-production systems.
