Grant support

We are grateful to the technical staff of CITA Research Center, and especially to A. Legua. A. Dominguez, J.R. Bertolin, and G. Tanco. Financial support for this project was provided by the Spanish Ministry of Economy and Competitiveness (INIA RTA2014-00038-C02-01, RZP2017-00001 and RZP2015-00001) and the Government of Aragon (Grant Research Group Funds, Group A14_17R and A14_20R). P.J. Rufino-Moya had a predoctoral grant from INIA.

Resúmen: BACKGROUND The objective of this study was to evaluate the effect of the proportion of pea (0%, 10%, 20%, and 30%), as a partial replacement for soybean meal (SBM) in the fattening concentrate, on ruminal fermentation in lambs. Gas and methane (CH4) production, in vitro dry matter degradability (IVDMD), ammonia (NH3-N), and volatile fatty acid (VFA) production after 24 h of incubation were evaluated. The concentrates were also incubated in the rumen of the wethers for 2, 4, 6, 8, 12, and 24 h to evaluate the effects of pea inclusion on in situ dry matter degradability (DMD), organic matter degradability (OMD), nitrogen degradability (ND), NH3-N, and VFA production. RESULTS In the in vitro assay, the inclusion of pea only affected gas production (mL day(-1) degraded dry matter), CH4 production (mL day(-1) degraded dry matter), and IVDMD (P < 0.05), and tended to affect NH3-N content (P < 0.10) without affecting VFA production. In the in situ assay, the inclusion of pea increased DMD, OMD, and ND linearly (P < 0.001), whereas pea inclusion decreased NH3-N content linearly (P < 0.05). Neither total VFA production nor the proportion of acetic acid were affected by pea inclusion (P > 0.05), but the propionic proportion increased with the proportion of pea included. CONCLUSIONS The best level of pea inclusion in the concentrate could not be established based on the results of this study. However, the results showed that the inclusion of pea provides a good alternative protein source. (c) 2020 Society of Chemical Industry
