Protein co-products and by-products of the biodiesel industry for ruminants feeding

Abstract

-The objective of the experiment was to classify 20 protein co-products and by-products of the biodiesel industry with potential to use in ruminant feeding. The meals evaluated were: cottonseed, canudo-de-pito, crambe, sunflower, castor-oil seeds detoxified with calcium, non-detoxified castor-oil seeds and soybean; and the cakes were: cottonseed, peanut, babassu, crambe, palm oil, sunflower, licuri, macauba seeds, non-detoxified castor-oil seeds, turnip and jatropha. The samples were quantified to determine dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE), neutral detergent fiber corrected for ash and protein (NDFap), non-fiber carbohydrates (NFC), acid detergent fiber corrected for ash and protein (ADFap), lignin, cutin and starch levels. The CP profile was characterized in fractions A, B1, B2, B3 and C. Some of these products can replace soybean meal, specially the Macauba seeds cake, cottonseed meal and peanut and turnip cakes based on digestive characteristics.

<b>Elephant grass silage with the addition of crambe bran conjugated to different specific mass

“…Probably the reduced EE contents in the crambe bran and in the elephant grass ensiled mass can have been decisive for this response. Although crambe is defined as an oleaginous plant, the crambe bran consists in the co-product obtained after the extraction of vegetal oil through specific solvents (Carrera et al, 2012). In this case, the high efficiency of the extraction through solvents provides an effective reduction in the EE contents of this coproduct (Table 1).…”

“…In tropical regions the crambe bran (Crambe abyssinica Hoschst.) a coproduct of the biofuel agribusiness, presents certain particularities in its bromatological composition, such as: high DM content and crude protein (Carrera et al, 2012;Souza, Goes, Silva, Yoshihara, & Prado, 2015). Thus, the use of crambe bran as an additive for tropical grasses ensilage will enable the increase of dry matter content and even enhance the crude protein content of the silage, making it possible to reduce the costs with the use of protein concentrates in diets, besides reducing possible impacts with the discharge of this co-product directly in the environment.…”

Effects of licury cake in young Nellore bull diets: salted sun‐dried meat is preferred rather than fresh meat by consumers despite similar physicochemical characteristics

“…Additionally, the use of byproducts in feeds for cattle is a viable alternative that replaces commercial ingredients (corn and soybean) and promotes an improvement in the physicochemical composition of the final product (meat or milk) . Additional studies need to be performed to understand how these ingredients affect the nutritional quality, as well as physicochemical and sensory characteristics, of meat and meat products …”

Effect of Crescent Inclusion of Sunflower Cake in Lamb Diets in Feedlot: Performance and Characteristics of Carcass

“…A torta de girassol apresenta teores médios de proteína bruta, extrato etéreo, fibra em detergente neutro corrigida, carboidratos não fibrosos, nitrogênio não-proteico, proteína degradada no rúmen e digestibilidade in vitro da ordem de 28,77%; 21,00%; 39,00%; 23,52%; 9,18%; 41,42%; 60,87%, respectivamente (Abdalla et al, 2008;Carrera et al, 2012). A inclusão de até 28% de torta de girassol em dietas para cordeiros reduziu o ganho em peso e a área de olho de lombo (Rodrigues et al, 2013).…”
