Hempseed has an excellent antioxidant content and is a rich source of essential amino acids and n-3 fatty acids. The objective of this paper consists on evaluating the hempseed Jubileu variety effects on performance, nitrogen (N) balance. The prediction of nitrous oxide (N2O) emissions was done as well. For 3 weeks of trial, a total of 15 pigs (39 kg ± 0.32) were randomly allocated individually in digestibility cages. Following a 7-day adaption period, there were two balancing periods where urine and feces were quantitatively collected. Two types of diet were used: Control group received a classical diet and Experimental group which received the same diet, supplemented with 5% hempseed. The growth parameter and carcass quality were not significantly altered by hempseed addition; however, a slight increased of ADG and feed conversion was noticed. Due to the significantly decreased of N concentration in the urine, TNO value was lower as well (P<0.05). A decline of N digestibility was noticed for HS group diet (P<0.001). Average value of N2O estimated was lower in HS fed group (P = 0.03). In conclusion, hempseed is a proteo-oleaginous source, which can be added in pigs’ diet with beneficial effect on performance, N metabolism indicators and N2O emissions.
