Kernel starch content is an important trait in maize (Zea mays L.) as it accounts for 65-75% of the dry kernel weight and positively correlates with seed yield. A number of starch synthesis-related genes have been identified in maize in recent years. However, many loci underlying variation in starch content among maize inbred lines still remain to be identified. The current study is a genome-wi...

The response of the common carp to diets with varying amounts of digestible starch, provided either as pea meal (LP, HP, 30 and 46% peas, respectively) or as cereal (LW, HW, 30 and 46% wheat, respectively), was studied and compared with the response to a carbohydrate-free protein-rich diet (CF). Here we focused on the utilisation of dietary carbohydrates by examining the relationship between di...

A process was explored for continuous enzymatic liquefaction of corn starch at high concentration and subsequently saccharification to glucose. The process appears to be quite efficient for conversion of starch to glucose and enzymatic liquefaction and should be readily adaptable to industrial fermentation processes. Preliminary work indicated that milled corn or other cereal grains also can be...

Since the cereal endosperm is a dead tissue in the mature grain, beta-oxidation is not possible there. This raises the question about the use of the endosperm oil in cereal grains during germination. In this study, mobilization of lipids in different tissues of germinating oat grains was analysed using thin-layer and gas chromatography. The data imply that the oat endosperm oil [triacylglycerol...

Factors that determine the digest1b11Hy of carbohydrates and mi nera 1 s 1 n cerea 1 s are examined . Most carbohydrates and minerals in cereals are structurally bound, either surrounded by or associated with cell wall components not easily digested by non-ruminant animals and humans. Treatments such as mechanical grinding and heat improve the digestibility of nutrient s . Further processing an...

ADP-glucose pyrophosphorylase (AGPase) provides the nucleotide sugar ADP-glucose and thus constitutes the first step in starch biosynthesis. The majority of cereal endosperm AGPase is located in the cytosol with a minor portion in amyloplasts, in contrast to its strictly plastidial location in other species and tissues. To investigate the potential functions of plastidial AGPase in maize (Zea m...

When cereal grain is fed to horses there is a risk of laminitis and it is also common to fmd behavioural changes characterised by chewing wood, eating bedding and grasping (wind sucking). This paper discusses the link between acidity in the gut, as a result of grain feeding, and the risk of laminitis and adverse behaviour. A proportion of the starch consumed as cereal grain passes undigested to...

Cereals represent the most important group of crops in the structure of plant production from the economic, agronomic and consumer point of view. Spelt wheat (Triticum spelta L.) is an ancient bread cereal related to wheat (Triticum aestivum L.) that has been cultivated for hundreds of years, and that is now being rediscovered in Europe and North America. Spelt is generating increasing interest...

Högberg, A. 2003. Cereal non-starch polysaccharides in pig diets. Influence on digestion site, gut environment and microbial populations. Doctoral thesis. ISSN 1401-6249, ISBN 91-576-6437-4 This thesis is based on three different studies comprising the weaning and the growing period, aiming at monitoring the influence of cereal non-starch polysaccharides (NSP) and dietary enzyme supplementation...

Maximising digestible energy (DE) yield from cereals is fundamental to optimising efficiency in pig and poultry production systems. Given the potential interaction between grain structure and composition and DE (or AME) yields in monogastrics, consideration must be given to cost–effective interventions that may improve available energy supply from grains. Processing options such as extrusion an...
