Food use of barley sprouts in organic sheep milk production. Hydroponic forage, used when fresh forage is scarce, represents a good alternative feed for milking ruminants, also in organic farming systems, where it can reduce the forage/concentrate ratio. This study evaluated the effect of barley sprouts (BS) in the diet on nutrients utilization and milk production from organic ewes. Eighteen ewes were divided into 3 groups and fed with 3 diets. Animals was fed with hay ad libitum and supplemented by: 0.6 kg/d of concentrate and 4 kg/d of BS (B100); 0.9 kg/d of concentrate and 2 kg/d of BS (B50); 1.2 kg/d of concentrate (C). Supplied and residual feeds and milk yield were recorded and sampled. Data were processed by mixed model. BS resulted richer in protein and fiber than barley grains, while the NSC, and starch in particular, were reduced. DM intake of ewes increased as BS amount increased in the diet (4230 vs. 4013 vs. 3760 g/d DM in B100, B50 and C; P |
