“…Increases in grass silage DM intakes and yields of milk and milk constituents due to protein supplementation were consistent with earlier studies (Khalili et al, 2002;Heikkilä and Toivonen, 2003). Despite lack of statistical differences VANHATALO A.…”

“…between the protein supplements in milk production, RSM seemed to increase yields of milk and protein (+3.8 and 0.136 kg/d) more than DP (+2.0 and 0.081 kg/d) or EP (+3.0 and 0.100 kg/d) in line with results of Khalili et al (2002). This is also supported by the higher omasal NAN fl ow and lower ruminal N absorption obtained with RSM as compared with pea treatments.…”

“…Peas have also succesfully substituted for rapeseed meal (RSM) on grass silage diet (Heikkilä and Toivonen, 2003), although in some cases peas have impaired milk production when RSM has been completely replaced with peas (Khalili et al, 2002). Peas have relatively high protein and starch contents, which both may contribute to reasonable production responses obtained with peas.…”

A 4 × 4 Latin square was conducted with four rumen cannulated cows to investigate responses to isonitrogenous supplementation of grass silage-cereal diet with rapeseed meal (RSM) or peas supplied either dried or ensiled. Omasal canal fl ow measurements showed that protein supplements increased non-ammonia N fl ow to the intestine, though pea supplements less than RSM. Plasma concentrations of branched chain and essential amino acids were also increased by both RSM and pea supplements. All protein supplements increased yields of milk and milk constituents compared to control, but these increases seemed to be less with peas than with RSM.

“…This was in line with the findings by Faldet and Satter (1991) who did not see any significant change of DMI on cows fed either soybean meal or heat treated soybean meal. However, the majority of studies in the literature report that protein supplementation increases DMI (Khalili et al 2002, Huhtanen et al 2011) which has been related to faster rate of fibre digestion in the rumen (Oldham 1984), and possibly to improved balance between AA and metabolizable energy (ME) in absorbed nutrients. The latter increases production that pulls intake (Huhtanen et al 2011).…”

“…Legume seeds have two advantages: they can be locally produced and can fix atmospheric N and thereby reduce the need for soil N fertilisation. Field pea is one of the most important legume seeds for organic farming (Khalili et al 2002). Field peas have high ruminal protein degradability, high energy value, but have rather low crude protein (CP) content (Loe et al 2004).…”

The aim was to study if locally produced organic legume seeds as protein supplement could improve the performance of dairy cows. The experiment was a cyclic change over design were the control diet consisted of grass silage and barley (60:40) on a dry matter (DM) basis. Barley was replaced with rapeseed expeller (RSE), or isonitrogenous supplements of peas, untreated field beans (UFB), heat-treated FB (TFB) or a lower level of TFB (TFB-low) that provided the same dietary metabolizable protein concentrations as of UFB. None of the legume protein supplementations had effect on DM intake (DMI) neither on energy corrected milk yield compared to control. The RSE treatment increased milk (24.8 vs. 23.6 kg d ) compared to other protein supplements. Heat-treated FB had no effect on DMI, milk or protein yield compared to UFB. Only RSE resulted in improvements in dairy cows performance in relation to the control diet.
