Low rumen pH depresses cellulose digestion and intake of roughage, leading to problems of acidosis and secondary ketosis due to off-feed conditions [ 23].
Too few studies reported results for fibre fractions or from other sources to permit pooling, but findings from one study suggested a possible protective association for cellulose and lignin intake for fatal CHD risk.
Constipation was clearly negatively correlated with low intake of cellulose and pentose fibres (p < 0.001).
Intakes (g/kg W0.75) of CP, NDF, lignin(sa), hemicellulose, cellulose, CT and DCP (P<0.01), and intakes of DOM, energy and N (g/day) (P<0.05) were higher for PE than for AG.
However, rats fed 5% chicory extract and cellulose had significantly higher food intake than those fed the control diet (P < 0.05).
Fumarate treatment did not affect weight change or feed intake but increased whole-tract digestion of gross energy, crude protein, and cellulose.
Intakes of crude protein (CP), lignin(sa), neutral detergent fibre (NDF), hemicellulose, cellulose, digestible CP (DCP) and OM (DOM), and N showed both linear and quadratic trends (L P<0.01; Q:P<0.01).
The intake of water produces a pressure that, in combination with other factors, pushes on the cellulose walls of the plant cells, thereby increasing the length, girth, and stiffness (turgor) of the cells and plant.
They found no associations between intake of total, soluble, insoluble, cereal, fruit, and vegetable fiber, as well as lignin and cellulose, and breast cancer risk among 89,835 women in the Canadian National Breast Screening Study.
In adolescents, PGX in solution (5 g) was shown to reduce energy intake from a pizza meal given 90 minutes later more effectively than less viscous fibres, such as glucomannan and cellulose (Vuksan et al., 2009).
