Detoxified Castor Seed Cake for Broilers

Abstract

The objective of the present study was to evaluate the effect of the dietary detoxified castor seed cake (DCC) inclusion on broiler performance and carcass traits. Two hundred and fifty Cobb-500® broilers were distributed according to a completely randomized experimental design consisting of five treatments (dietary inclusion of 0.0, 2.5, 5.0, 7.5, and 10.0% DCC) with five replicates of 10 birds each (five males and five females). Feed intake (FI), body weight gain (WG), and feed conversion ratio (FCR) were evaluated from one to 40 days of age. Carcass yield and the yields of the breast, leg (drumstick+thighs), and wings were determined when broilers were 40 days old. Live performance parameters were influenced by DCC dietary inclusion, and levels 2.00, 1.38, and 1.25% DCC impaired FI, WG, and FCR, respectively. Carcass and parts yields were not affected by dietary DCC inclusion. It was concluded that the addition of DCC levels up to 1.25% to broiler diets does not impair live performance or carcass traits.

“…The castor bean meal is generated from mechanical pressing, a step during which around 50% of the oil is removed, followed by the extraction of solubles (hexane, heptane, or petroleum ether) (Faria Filho et al, 2016). The extraction process generates wastes such as glycerin, cake, meal, and husks (Silva et al 2014).…”

“…Many by-products are left behind after oil seed pressing, which is also of great value as highly nutritious feed additives for livestock [ 10 , 11 ] and fish [ 12 ]. However, castor seed meal and castor press cake currently cannot be used in industrial recycling due to the presence of two highly toxic compounds: toxalbumin called ricin, which accumulates predominantly in the seed coat and promotes a direct cytotoxic effect by inhibition of protein biosynthesis through enzymatic ribosome inactivation; and ricinine, a small alkaloid, present in the castor seeds, the toxicity of which is significantly less than ricin [ 13 , 14 ].…”
