Abstract: The aim of this research was to evaluate the effect of supplementation with two barley forage genotypes on milk production and quality in grazing cows. The genotypes evaluated were a local barley (Hordeum vulgare L.) and UNALM 96 M6h-326 barley in the district of Sincos, Junín (Peru). The experiment was conducted with 16 Brown Swiss - creole crossbred cows in second lactation and body weight of 385 ± 17 kg. Under a simple change design, the animals were divided into two groups for supplementation with 4 kg/day with one of the two barley forages. Supplementation was carried out in two stages of 13 days each, the first 8 days being for adaptation and the following 5 days for evaluation of milk production and composition. Milk production per cow/day was increased with UNALM 96 M6h-326 barley forage compared to the local variety (4.0 vs. 3.57 kg. p<0.05). Likewise, higher urea content in milk was obtained, but the fat content was lower (p<0.05).
