“…Different types of seed processing can reduce or eliminate this toxin [128,129]. For instance, it can be detoxified with calcium oxide replacing up to 50% of soybean meal in lambs' diet [127] and reducing the production costs in a beef cattle grazing system [130]. Furthermore, up to 15% non-detoxified CB meal can be used in goat feed [131].…”

Biofuel Production with Castor Bean: A Win–Win Strategy for Marginal Land

et al. 2020

The urgency to reduce resource depletion and waste production is expected to lead to an economy based on renewable resources. Biofuels, for instance, are a great green alternative to fossil fuel, but they are currently derived from edible vegetable oils such as soybean, palm, and sunflower. Concerns have been raised about the social–economic implication and ecological impacts of biodiesel production. Cultivating new lands as biodiesel feedstock rather than food supply, with the consequent increase in food prices, leads to so-called indirect land-use change (ILUC). Establishing bioenergy crops with phytoremediation ability on contaminated soils offers multiple benefits such as improving soil properties and ecosystem services, decreasing soil erosion, and diminishing the dispersion of potentially toxic elements (PTEs) into the environment. Castor bean is an unpalatable, high-biomass plant, and it has been widely demonstrated to possess phytoremediation capability for several PTEs. Castor bean can grow on marginal lands not suitable for food crops, has multiple uses as a raw material, and is already used in biodiesel production. These characteristics make it perfect for sustainable biodiesel production. Linking biofuel production with environmental remediation can be considered a win–win strategy.

“…The greatest feed conversion for the goats that received the diets with DCC is probably related to the possible higher digestibility of the diet, as previously mentioned. Nicory et al (2015) evaluated the substitution of soybean meal by castor oil meal in lamb diets and did not observe any effect on average daily, total, and feed conversion gains.…”

This study aimed to evaluate the influence of the substitution of soybean meal (SM) by detoxified castor cake (DCC) by two alkaline products on intake, performance and on the growth curve of goat’s kids. 24 were used, Saanen goats (n=12) and Anglo Nubian (n=12), with initial body weight of 16.2±0.67 kg, initial age of 3 months and confined during the growth phase. The treatments consisted of three diets: a standard diet formulated with a traditional protein source, the soybean meal (SM); and test diets, which consisted of a protein source alternative, differing detoxification processes, on the basis of calcium hydroxide (Ca(OH)2) or sodium hydroxide (NaOH). The animals were distributed in a completely randomized design, in factorial 3 x 2 (diet SM, Ca(OH)2 DCC and NaOH DCC x Saanen and Anglo Nubian) totaling six sessions with four replicates each. The experimental period lasted 270 days. The non-linear models used were the Gompertz and Logistic. There was no effect (P < 0.05) of diets on the intake of nutrients, but there was no effect (P > 0.05) of breeds and interaction between both factors. The intake of DM during the phase of growth was greater for the goats fed with SM. There was no effect (P>0.05) of diets nor of the breeds in the ADG. Feed conversion was influenced (P < 0.05) by the diets, in which the goats fed diets with DCC presented better feed conversion. It has been observed that both models had good adjustments, with values numerically superior to 90%, however, the logistic model showed higher R2 and, at the same time, asymptotic index (AI). Despite the ADG be equal, the breeds presented absolute growth rate (AGR) vary over time, where the Saanen goats reached the peak first (181 days), with AGR of 0.14 kg day-1. However, even the goats Anglo Nubian reaching the highest peak late, the AGR was higher, around 0.16 kg day-1 higher than the Saanen. Both castor cake has the potential to replace the SM on a diet of goat’s kids during the growth phase. The mathematical model of Logistics estimates more accurately the growth of Saanen goats and Anglo Nubian, being that the rate of absolute growth is greatest in goats Anglo Nubian.

Animal performance mainly depends on the quantity and quality of forage available as feed and animal feed represents one of the major costs in animal production. This research was conducted in the Faculty of Natural Resources and Environment Experimental Field at University for Development Studies, Nyankpala Campus to evaluate the relative feed value of four indigenous savanna forage shrubs. These shrubs were cultivated and their leaves harvested at 7, 10 and 13 weeks after establishment. Harvested leaves were pulverized to determine ash, crude fat, crude fiber, crude protein, neutral detergent fibre (NDF) and acid detergent fibre (ADF). Metabolisable energy, dry matter (DM), digestible dry matter (DDM), dry matter intake (DMI) and relative feed values (RFV) were also estimated. Ash, crude fat, crude fibre, CP, ADF and NDF contents ranged from 7.56 to 11.22%, 1.924 to 2.812%, 9.33 to 16.11%, 4.598 to 4.960%, 20.73 to 27.22% and 33.47 to 53.06%, respectively. The DDM, DMI and RFV ranged from 67.70 to 74.84%, 2.27 to 3.66% and 120.2 to 212.6%, respectively. The NDF, ADF contents of Tephrosia purpurea was significantly higher than those for Cajanus cajan (L), Stylosanthes mucronata and Securinega virosa (P < 0.05). The DDM and RFV of S. virosa and S. mucronata were significantly higher than those for C. cajan and T. purpurea. The DMI in S. virosa and S. mucronata was significantly higher than those for other shrubs. The carbohydrate contents of S. virosa were significantly higher than the other shrubs. In conclusion all the species studied offered considerable potential as high quality forage for ruminants during the acute periods of the year when the quantity and quality of forages are limited.
