Thus, it aimed to compare meta-analytically the soybean meal degradability parameters with alternative meals from other plant species. They were used experiments that had parameters for ruminal degradability of protein concentrated feeds. The database was composed of 82 treatments from 15 works, comparing soybean meal with cotton seed meal, rapeseed and sunflower. The potentially degradable fraction and the effective degradability of the dry matter with 5%.h-1 were lower (P = 0.0011 and P = 0.0268 respectively) for the alternative meals. The contents of crude protein (CP) of the alternative meals are smaller (P = 0.0012) compared to soybean meal. The readily soluble fraction in water for CP was higher (P = 0.0017) for alternative meals. The potentially degradable fraction of CP was higher (P <0.0001) for soybean meal. The effective degradability to 8%.h-1 of CP was higher for alternative meals (P = 0.0357) than that for the soybean meal. Partial or total replacement of soybean meal by cottonseed meal, rapeseed and sunflower alter the ruminal degradability parameters of the dry matter and crude protein. The protein soybean meal is more available to rumen microorganisms and less available for animal compared to the protein of the alternative meals (cotton, rapeseed, and sunflower).</em></strong>}, number={3}, journal={Asian Journal of Agriculture and Food Sciences}, author={Busanello, Marcos and Velho, João Pedro and Tambara, Antônio Augusto Cortiana and Alessio, Dileta Regina Moro and Thaler Neto, André and Haygert-Velho, Ione Maria Pereira}, year={2016}, month={Jun.} }
