Introduction Plant carbohydrates can be classified into three categories: 1) simple sugars and their conjugates (glucose, fructose, etc.); 2) storage reserve compounds (starch); and 3) structural carbohydrates (cellulose, hemicellulose, etc.). Simple sugars and storage compounds are primarily digested in the upper gastrointestinal tract of pigs, although not completely, while structural carboh...
Good day. Sticking exclusively to the processing/treatment, I would like to specify some aspects to improve the use of fiber in pigs: - It is important to quantify the particle size of the most relevant grains, such as grasses: maize, sorghum and legumes: Soy, for example. The studies conclude that particles of maize grain and GF sorghum with respect to grains> 1,000 μm. In the case of Soy, it has been shown that between 600 and 700 μm is the recommended range in most diets for pigs (rearing and adults). Other species of grains such as wheat, rapeseed, etc., does not necessarily follow the aforementioned tendency; which has generated some uncertainty and discouragement in some researchers. In my opinion, I consider that the atypical behavior of these is mainly due to its different germplasm pattern. - With respect to pelletizing, it has been shown that this processing produces an increase in C.A between 4 and 12%, as well as ADG. -Finally I consider it appropriate to highlight some studies regarding the beneficial treatment of NaOH, which as a hydrolytic agent can solubilize the CPC (hemicellulose-lignin matrix and silica), therefore pigs fed with sorghum treated with NaOH increased the digestibility of N and Energy, In another study; pigs fed Leucaena leucocephala flour had better N retention compared to pigs fed untreated Leucaena leucocephala. Apart from the above, it is unquestionable that more research should be carried out consistently. Best regards from Peru.
It is appropriate to narrow down the relevance of the dynamic interaction at the intestinal level of enteric microbiota of pork. Therefore, in the context of the forum, the link of the triad: Enzyme- Probiotic-Substrate (especially lignocellulosics) can not be ignored. Given the leading role played by the first two: fibrolytic degradation and fermentation, respectively on the substrate and conceptualizing the occurrence of various biochemical events is conducive to evaluate in an integrative way the intestinal microbial biomass and the assertive use of multienzymes and exogenous probiotics, as well as the parallel occurrence of the symbiosis and exclusion of the last of the mentioned; lead us to the achievement of satisfactory polyvalent parameters: in production, immunophysiological and reproductive in pigs.
For this reason I suggest the use of multienzymes associated to probiotics, with a composition enriched with their respective referents (which are already known); as an important strategy to achieve a significant performance in the achievement of improvement of the digestion of the fiber in the swine.
Best regards.
