Nutritive Evaluation of Mechanically-Pressed Camelina (Camelina sativa), Carinata (Brassica carinata) and Soybean (Glycine max) Meals for Broiler Chickens
MetadataShow full item record
Three digestibility experiments were conducted to evaluate the nutritive value of mechanically-pressed camelina (MPCM), carinata (MPCARIM) and soybean (MPSBM) meals. Growth trials were conducted to determine effects of camelina and soybean meals on broiler performances. The 11.5% residual oil MPCM had higher nitrogen-corrected apparent metabolizable energy (AMEn) than 14.5% oil MPCM. Carbohydrase improved AMEn of MPCM. Heated MPCM showed a lower AMEn than non-heated MPCM. Lipase and no-heat gave highest AMEn for 7% oil MPSBM. Carbohydrase and heat had highest AMEn in 11% oil MPSBM. Carbohydrase and wet-heat gave highest AMEn for 12.5% oil MPCARIM. Lipase and wet-heat showed highest AMEn for 16.5% oil MPCARIM. Heat did not alter standardized ileal amino acid digestibility (SIAAD) of MPCM, improved SIAAD in MPSBM. Oil levels affected some SIAAD and enzymes improved SIAAD of MPCM and MPSBM. MPCM and MPSBM can be incorporated up to 10% in starter, grower and finisher broiler diets.
