Two experiments were conducted to determine the content of DE and ME as well as the AID and SID of CP and AA in barley grains obtained from Australia, France or Canada.
In Exp.1, 18 growing barrows (Duroc × Landrace × Yorkshire; 31.5 ± 3.2 kg) were individually placed in stainless-steel metabolism crates (1.4 × 0.7 × 0.6 m) and randomly allotted to 1 of 3 test diets. In Exp. 2, eight crossbred pigs (30.9 ± 1.8 kg) were allotted to a replicate 3 × 4 Youden Square designed experiment with three periods and four diets. Two pigs received each diet during each test period. The diets included one nitrogen-free diet and three test diets.
The relative amounts of GE, CP and all AA in the Canadian barley were higher than those in Australian and French barley while higher concentrations of NDF, ADF, total dietary fiber, insoluble dietary fiber and β-glucan as well as lower concentrations of GE and EE were observed in the French barley compared with the other two barley sources. The DE and ME as well as the SID of histidine, isoleucine, leucine and phenylalanine in Canadian barley were higher (p < 0.05) than those in French barley but did not differ from Australian barley.
Differences in the chemical composition, energy content and the SID and AID of AA were observed among barley sources obtained from three countries. The feeding value of barley from Canada and Australia was superior to barley obtained from France which is important information in developing feeding systems for growing pigs where imported grains are used.
