  Cold-pressed hempseed cake was investigated as a protein feed for young calves and finishing steers. Half of the animals were fed cold-pressed hempseed cake, whereas the other half were fed a mixture of soybean meal and barley. Effects on feed intake, liveweight gain (LWG), faecal traits and carcass traits (steers only) were studied. Neutral detergent fibre intake was higher for animals fed hempseed cake than for those fed soybean meal (P<0.05). In addition, the number of long particles in faeces was lower (P<0.05) and faecal dry matter content and consistency were higher from animals which were fed hempseed cake (P<0.05; steers only). Higher feed intakes in calves fed hempseed cake (P<0.05) combined with similar LWG resulted in lower feed efficiency in hemp-fed calves (P<0.05). In conclusion, hempseed cake compared to soybean meal as a protein feed for intensively fed growing cattle results in similar production and improved rumen function.

  Sixteen Swedish Red steers were fed a hempseed cake (HC) or soybean meal (SM) protein supplement. Lipid extract from fresh and cooked M. longissimus dorsi were analysed. Diet comparison showed that HC had increased monounsaturated fatty acid proportion, primarily 18:1 cis-9 in the meat (P<0.05). Additionally, HC steers had higher proportions of 18:1 trans-11 and 18:2 c-9, t-11 (P<0.05). Furthermore, HC steers had decreased n-6/n-3 fatty acid ratio compared to SM steers (P<0.05). Cooking increased polyunsaturated fatty acid (PUFA) and n-6 level, particularly 18:2n-6 and 20:4n-6 (P<0.05). Cooking decreased the proportion of 17:0 and 18:0 (P<0.05). In polar lipid, HC steers had lower saturated fatty acid (P<0.05) and higher PUFA levels (P<0.05). Warner-Bratzler shear force and lipid content were unaffected by dietary treatment. Cooking decreased the triacylglycerol level of both groups (P<0.01). We conclude that HC is a viable alternate supplement for beef diets which improves the meat FA profile.
