Inclusion of Cocoa Bean Shell in the Diet of Dairy Goats: Effects on Milk Production Performance and Milk Fatty Acid Profile

Abstract: The use of agro-industrial by-products in animal nutrition is a promising strategy to reduce the food-feed competition, the diet cost at farm level and the environmental impact of animal-derived food production. In this study, the suitability of cocoa bean shell (CBS), a by-product of the cocoa industry, as a feed ingredient in the diet of dairy goats was evaluated, with a focus on the related implications on feed intake, milk yield, milk main constituents, and fatty acid (FA) profile of milk fat. Twenty-two C… Show more

“…In fact, our group has previously published similar results induced by the intake of GSPE in lactating rats [ 25 ]. However, a great number of studies relate the intake of various sources of polyphenols to an increase in milk production and milk fat concentration [ 47 , 48 , 49 ], or to a null effect in these parameters [ 50 , 51 ], mainly in ruminants. Thus, it is probable that these discrepancies reflect the genetic and metabolic differences between animal species as well as differences in the polyphenol’s composition and concentration of the studied extracts.…”

“…De igual manera Omotoso, en el 2019 público un informe en relación al valor nutricional de los compuestos de la cascara de mazorca de cacao en rumiantes, cuyos resultados mostraron un significativo valor nutricional para este sector, beneficio que podría ser mejorado con el agregado de urea al 5% (Omotoso, 2019). Esto se ve fundamentado por el estudio publicado por el equipo de investigadores de Campione donde determinaron que la leche de ovejas alimentadas con CC poseen menos concentración de urea a causa de una distinta eficiencia en el uso de nitrógeno en el rumen, por lo que se requiere que se añada urea al suplemento, a fin de alcanzar los valores normales de urea que posee la leche (Campione et al, 2021) (Renna et al, 2022).…”

“…Diversos autores han estudiado la fracción poli fenólica de la CC, evidenciándose una alta variabilidad segun las condiciones de extracción. En el estudio de Campione y col la cantidad de polifenoles es 4,8 veces mayor que los valores encontrados por el equipo de investigación de Renna (Campione et al, 2021;Renna et al, 2022;Hikmah et al, 2020).…”

“…The potential of CBS as an ingredient for animal feed has always been studied in order to reduce the environmental impacts derived from waste disposal, diet costs at the farm level and food-feed competition [56,157]. For example, Emiola et al, 2011 [158] evaluated the effect of CBS feeding on laying hens.…”
