“…With that in mind, the castor bean cake is a by-product obtained from oil extraction and has interesting nutritional value and digestibility, however it contains toxic substances such as ricin and ricinus agglutinin according to Dang and Vam Damme (2015), which prevents its use in the in natura form in animal feeding. However, safe and economically feasible detoxification methods already exist (Andrade et al, 2019), with promising reports of its use in animal production (Santos Neto et al, 2019;Araújo et al, 2020).…”

The purpose was to evaluate structural characteristics of pasture, behavioral aspects and physiological parameters of sheep finished on irrigated Tamani grass pasture under continuous stocking, using castor bean cake as alternative input. Structural characteristics of the pasture were assessed in a randomized block design in 2 x 2 factorial arrangement, with two sources of nitrogen fertilization (mineral - urea and organic - in natura castor bean cake) and two supplements (with or without detoxified castor bean cake), in four replications (paddocks). Behavioral aspects and physiological parameters were assessed in a randomized block design with four treatments, and repeated measures over time in eight replications (sheep). Total forage biomass, green leaf blade biomass, grazing, rumination, and idleness times, as well as respiratory rate and rectal temperature were assessed. Urea provided greater leaf blade biomass (1,807 kg DM.ha.cycle-1) and tiller population density (1,592 tillers.m-2). Grazing time reduced 65 minutes.day-1 for animals supplemented with detoxified castor bean cake and kept in pastures fertilized with urea. The use of castor bean cake did not change the physiological parameters of the animals in any of the managements evaluated and can be used as a strategic input in the finishing of sheep on pasture.

“…Castor bean cake is a protein-energy feed that digests well. Although its use in the in natura form for animal feeding is limited because it contains toxic substances such as Ricinus communis agglutinin , ricinin, and allergen complex (Dang and Van Damme 2015 ), but a safe detoxification method (Andrade et al 2019 ), with satisfactory responses in animal production (Santos Neto et al 2019 ; Araújo et al 2020 ), can be performed.…”

The purpose of this study was to evaluate castor bean cake as alternative input in the control of gastrointestinal parasites in sheep raised on irrigated pasture under continuous stocking. The treatments consisted of sheep supplemented with standard diet and pasture fertilized with urea; sheep supplemented with alternative diet and pasture fertilized with urea; sheep supplemented with standard diet and pasture fertilized with in natura castor bean cake; and sheep supplemented with alternative diet and pasture fertilized with in natura castor bean cake. A randomized complete block design (CBD) was used, with 16 replications (sheep), with repeated measures over time, the plots being the treatments, and the subplots the collection times. Infective nematode larvae in the pasture (L3.g DM −1 ), number of eggs per gram of feces (EPG), globular volume (GV), and total plasma protein (TPP) were evaluated. For adult gastrointestinal parasite counts, CBD was also used with six replications. Except for FAMACHA © grade, all variables had effect ( P < 0.01) of the time factor. The average number of L3.g DM −1 and EPG were 126 and 841, respectively, with no effect ( P > 0.05) of the treatment factor. The values observed for GV and TPP were higher than 25.9% and 6.4 g·dL −1 , respectively, which were considered normal. As organic fertilizer, the fractionated application of in natura castor bean cake does not reduce the contamination of pastures by nematode larvae. The evaluated feeds improve the resilience of the sheep to infection by gastrointestinal parasites. The treatments using castor bean cake reduced the adult parasites present in the abomasum of sheep.
