EnglishThe aim of this work was to study the digestibility of acorn (Quercus cerris) in comparison with barley, employing barrows (6 Cinta Senese and 6 Large White) submitted to four trials in metabolic cage. Cinta Senese and Large White pigs did not differ for the digestive ability of all the nutritive fractions. Acorns showed lower digestibility coefficients than barley for all the fractions especially for fibre and protein. The real digestibility of protein has been evaluated through a regression on the apparent digestibility of 4 diets with variable levels of protein. The endogen protein resulted 15,70 g in 100 g of faecal D.M. In consequence the real digestibility of acorn protein was estimated 69,37 %.The digestive utilization of acorn’s energy is lower than that of barley (54% vs. 84%). The D. E. of acorn is about 10 Mj/kg/SS. In conclusion the acorn (Quercus cerris) has a low protein value, probabily because of its high content of tannins. Therefore the use of acorn in pig nutrition, particularly in the first phase of growth, needs of suitable supplementation.
