The objectives of this study were to examine the effect of feeding newly developed blend pelleted products (BPP) based on carinata meal (BPPCR) or canola meal (BPPCN) in combination with pulse screenings (low grade of pulse seeds) and lignosulfonate on lactation performance and ruminal degradation kinetics in high-producing dairy cows. In this study, 9 mid lactating (3 canulated + 6 non-cannulated) Holstein cows (body weight: 679 ± 124 kg; days on milk = 96 ± 22; average parities = 3) were randomly assigned to one of the following 3 dietary treatments: T1 = control diet (Con; common barley-based diet in western Canada); T2 = basal diet supplemented with 12%DM BPPCR (carinata meal 71.4% + pea screenings 23.8% + lignosulfonate 4.8%DM), and T3 = basal diet supplemented with 13%DM BPPCN (canola meal 71.4% + pea screenings 23.8% + lignosulfonate 4.8%DM) in triplicate 3 × 3 Latin square design. Each experimental period lasted for 21 d with14 d for adaptation and 7 d sampling. The data were analyzed using the Mixed model procedure in SAS 9.4 with the analysis triple LSD model including treatment, square, period, and cows effects. The treatment differences were compared using Tukey method. The results showed that there were no differences (P > 0.05) between treatments in milk yield (averaging 47.4 kg/d; SEM = 1.56) and fat corrected milk (averaging 46.3 kg/d, SEM = 1.60). There was no effect (P > 0.05) of dietary treatments on milk composition or milk component yield. The feed efficiency expressed as fat corrected milk / DMI was not affected (P > 0.05) by the treatments (averaging 1.8; SEM = 0.05). There was no effect (P > 0.05) of the blend pelleted products on the ruminal degradation kinetics of DM and CP. The Implication of this study is that the blend pelleted products based on carinata meal as a new co-product from bio-fuel processing industry is equal to the other pelleted products based on canola meal as a protein source for dairy cattle without affecting performance and rumen degradation kinetics of feed in high producing dairy cows.
