The aim of the present work was to evaluate palatability, apparent digestibility, nitrogen balance and nutritive value of diets based on different level of pea seeds (Pisum sativum var. Classic) comparing to soybean meal. Six Sarda breed wethers were used in a two replicated 3 x 3 Latin Square design. Animals were fed three periods with three experimental diets. Diets were formulated on the basis of natural meadow hay (CP: 11,0%, NDF: 59,6% on DM basis). Two diets contained different levels of pea seeds: 23% (P23) and 48% (P48) as fed, with a crude protein content of 12.6% and 15.2% (on dry matter basis) respectively. The third, used as reference diet, was based on soybean meal (S), as protein source, with a crude protein content of 14.5%. Apparent digestibility values and statistical differences (A,B: P<0.01) for OM were: 69.7A% (P23), 76.2B% (P48) and 67.5A% (S), for crude protein: 70.9% (P23), 74.7% (P48) and74.3% (S). A positive nitrogen balance was observed with the following values: 2.8 g/d (F20), 3.8 g/d (F38) and 3.8 g/d (S). Nutritive value of diets was: 0,74A (F20), 0,83B (F38) and 0,71A (S) French Milk Feed Unit/kg. Results showed that pea seeds can be utilized to replace soybean meal in sheep.

Abstract
The aim of the present work was to evaluate palatability, apparent digestibility, nitrogen balance and nutritive value of diets based on different level of pea seeds (Pisum sativum var. Classic) comparing to soybean meal. Six Sarda breed wethers were used in a two replicated 3 x 3 Latin Square design. Animals were fed three periods with three experimental diets. Diets were formulated on the basis of natural meadow hay (CP: 11,0%, NDF: 59,6% on DM basis). Two diets contained different levels of pea seeds: 23% (P23) and 48% (P48) as fed, with a crude protein content of 12.6% and 15.2% (on dry matter basis) respectively. The third, used as reference diet, was based on soybean meal (S), as protein source, with a crude protein content of 14.5%. Apparent digestibility values and statistical differences (A,B: P<0.01) for OM were: 69.7A% (P23), 76.2B% (P48) and 67.5A% (S), for crude protein: 70.9% (P23), 74.7% (P48) and74.3% (S). A positive nitrogen balance was observed with the following values: 2.8 g/d (F20), 3.8 g/d (F38) and 3.8 g/d (S). Nutritive value of diets was: 0,74A (F20), 0,83B (F38) and 0,71A (S) French Milk Feed Unit/kg. Results showed that pea seeds can be utilized to replace soybean meal in sheep.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
