Summary We aimed to evaluate the effects of maternal nutrition (MN) and foetal sex on the intestinal development ofbovine foetuses throughout different days of gestation (DG). Forty-four multiparous, dry Holstein 9 Gyr cowswith average initial body weight of 480 +/_ 10 kg were fed the same diet of either restricted feeding at 1.15% ofbody weight (CO, n = 24) or fed ad libitum (overnourished, ON, n = 20). Six cows from CO group and five cowsfrom ON group were slaughtered at 139, 199, 241 and 268 DG, and foetuses were necropsied to evaluate theintestinal development. The mass, length and density of foetal intestines were not affected by MN (p ≥ 0.260).An interaction between MN and DG was observed for the villi length of jejunum (p = 0.006) and ileum(p < 0.001). Villi length of jejunum and ileum was higher (p < 0.10) in foetuses from ON-fed cows than in foe-tuses from CO-fed cows at 139 DG. However, at 199 DG, the villi length of jejunum and ileum of foetuses fromCO-fed cows was higher than in foetuses from ON-fed cows. Despite these differences, MN did not affect the villilength of jejunum and ileum at 268 DG (p > 0.10). Female foetuses had greater small intestine mass (p = 0.093),large intestine mass (p = 0.022), small intestine mass in proportion to body mass (p = 0.017) and large intestinemass in proportion to body mass (p < 0.001) than male foetuses. Female foetuses had also longer small intestine(p = 0.077) and greater small intestine density (p = 0.021) and villi length of jejunum (p = 0.001) and ileum(p = 0.010) than males. We conclude that MN affects the pathway for the development of foetal villi lengththroughout the gestation in bovine foetuses without changing the final villi length. Female foetuses had higherintestinal mass, density and villi length than males during the foetal phase in bovines.

I. INTRODUCTION
Soil organic matter (SOM) is constituted of, basically, two types of substances: humic (humic acid (HA), fulvic acid (FA) and humin (H)) and non humic (proteins, amino acids, polysaccharides, organic acid of low molecular weight, waxes and others). The humic substances (HS) are the most recalcitrant components of soil organic matter, and they are constituted of an heterogeneous mixture of functional groups. These are formed during the humification process, which modilies chemical structures of OM through the degradation of organic residues, being controlled through variables such as temperature, soil water regime, pH and free nutrients. The study of SOM, in particular of the
HS, has shown necessary and very important to understand mechanisms of its formation and stabilization. Its characterization is relevant because it has a function in the productivity and structure of soil.
Spectroscopic techniques which make possible studies of OM near natural situation are interesting, mainly if they work with low negative interference of intrinsic components of this material, such as metals. In this direction, a new technique has being applied: Laser-lnduced Fluorescence (LIF) spectroscopy. This technique presents, in recent and preliminary results, an indicative of high potential to evaluate humification degree of OM in whole soil through a relatively simple methodology.
However, physical and chemical parameters generate effects that inlluence the LIF. These , effects are not known yet, as well as the parameters which generate them. The concentration is a parameter that affects the LIF intensity, and can easily be controlled in laboratory. The goal of this work is to understand the dependence of soil HA fluorescence as a function of concentration, to evaluate which range of organic matter concentration the methodology can be applied.
