Furthermore, the results showed stimulatory effect of the [alpha] - galactosides on height of the villi, surface area and crypt depth in all studied segments of the intestine in the in ovo experimental group (P [?] 0.05) at day of hatch.

Searching methods that stimulating the rate of development of the gastrointestinal tract, especially the small intestine, [alpha] - galactosides became the subject of concern, which is ubiquitously occurring in compounds of plant seeds.

(24,35) Galectin-3 has a particular molecular region that has an affinity for the sugar galactose and its bonds to adjacent molecules, which are called galactoside bonds.
D-chiro-Inositol and its galactosides (fagopyritols) have potential medicinal importance in lowering symptoms of NIDDM (Lamer et al., 1988; Asplin et al., 1993; Romero and Larner, 1993; Ortmeyer et al., 1995; Kawa et al., 2003) and PCOS (Nestler et al., 1999).
The major explant feeding experiment was designed to quantify the accumulation of cyclitol galactosides in mature, dry seeds after feeding solutions containing free cyclitol substrates to soybean explants.
Total D-pinitol (free D-pinitol plus pinitol galactosides) concentration was not higher after feeding D-chiro-inositol than in the control treatment, myo-Inositol and galactinol concentrations were not different than in the control treatment after feeding D-chiro-inositol.
Galactosyl cyclitols, raffinose, or stachyose were not detected in leaf tissue disks or in seed coat cup exudates indicating the absence of galactosyl cyclitols in leaves and suggesting that free cyclitols are transported from maternal tissues to soybean embryos where they are converted to their respective galactosides.
The galactosides introduced were derived as a result of the process of extraction of the residue after debitering of bitter lupin seeds (Gulewicz et al., 2000).
Drawing on the present research, one can formulate a hypothesis that the injection in ovo of a- galactosides derived from the debitering process of bitter lupin seeds affects the rate of the resorption of the content of the yolk sac, which can lead to ensuring the optimal amount of energy for chicks which have to deal with the new environmental conditions.
For corn-soybean meal based feed that are most widely used in Americas and Asian countries, types of NSPs that interfere energy digestibility are galactosides, mannosides, soybean oligosaccharides (raffinose, stachyose, and verbascose).
