It is well known that castor seeds contain a poisonous toxin ricin. For farmers and other agriculturists involved in cultivation of castor and other vegetable crops, there would be a feeling of uncertainty as to whether cultivation of castor and other vegetable crops can be done in the same land, due to the poisonous nature of castor seed.
It should be noted that not the entire castor plant is poisonous; the toxin ricin is present only in castor seeds. Even the castor oil extracted from the seeds does not contain any toxin. Only the castor meal contains ricin. Once the plant is harvested and the residue cleaned up at the end of the growing season, there is no poison left out in the cultivated space; hence there is no harm in cultivating other vegetable crops in the same space where castor was cultivated.
Castor oil and meal has many benefits. Castor oil has been used as a purgative since long and still finds many advanced applications. Castor meal is now being utilized in some commercial repellent sprays for squirrels, rabbits, moles and other garden pests.

Scientists from Brazil conducted an experiment to evaluate the replacing levels of soybean meal with castor seed meal in diets for lambs on the productive and metabolic parameters. The lambs were fed with varying concentrations of castor seed meal replacing soybean meal. The experimental setup was completely randomized with five treatments and ten replicates.
The experimental results showed that despite the decreased intake, nutrient digestibility and nitrogen balance, castor seed meal could replace 50% of soybean meal without changing the lamb’s blood parameters or performance.
Researchers at Brazil conducted a study to understand the effect of replacement of soybean meal by wet or dry castor bean meal in diets of feedlot lambs. They assessed animal performance, carcass traits, intake, digestibility and hepatic function.
Control animals were fed with soybean meal while lambs for test were fed with dry or wet castor meal treated with calcium hydroxide for 70 days. Lambs were slaughtered and evaluated at the end of 70 days. Dry matter intake and digestibility, final body weight, average daily gain and carcass weights were not affected by the substitution of soybean meal by castor source.
Serum levels of aspartate aminotransferase and alanine aminotransferase enzymes did not differ among treatments indicating no effect of treated CM on hepatic function.
The results show that the castor meal can completely replace soybean meal in the diet of finishing lambs without negative impacts.
In India, the ministry under Mamata Banerjee has re-classified de-oiled cakes and oil meals from Class 110 to Class 120, effective December 27,2010 which will entail a freight rate increase between 11 and 13 per cent. Since oil cake and meals are used effectively as high nutrient bird and animal feeds, the rise in raw material prices will be passed on to consumers.
Solvent Extractors Association (SEA), in a memorandum to the railways minister and chairman of the Railway Board as well as secretary, Ministry of Agriculture, Commerce, Animal Husbandry and Finance, highlighted that de-oiled cakes were locally produced, traded and occasionally exported on wafer-thin margins. This increase in freight rate would make the production of de-oiled cakes unviable thereby forcing many processing plants to decrease their production and thereafter leading to
De-oiled cakes end-use is in manufacture of compound feeds for cattle, poultry and aqua and also as natural fertilisers and hence such a large increase in freight would place great constraint on the viability of dairy and food industry as well as on the farmers. Also, exports of de-oiled cakes, which face stiff international competition from giants in the US and South America, will be adversely affected. In fact, to compete in the international market, the government has granted a 2 per cent incentive under the Focus Product Scheme for exports of some de-oiled cakes and 5 per cent under Vishesh Krishi Gram Upaj Yojana for castor de-oiled cake. The hike in freight will totally nullify the benefit granted to the exporters of de-oiled cakes and would place them at a great disadvantage.
