Ricinus Communis L

A feeding trial was conducted to determine the effect of graded levels of dehulled and cooked castor oil bean (Ricinus communis L) meal (CBM) and supplementary DL-methionine on growth performance and certain blood parameters of broiler finishers. One hundred and eighty 6-week old broiler birds (Anak strain) were randomly divided into 12 groups of 15 birds each. The groups were randomly assigned to 12 isocaloric (2.90 Mcal/kgME) and isonitrogenous (21.00%CP) diets in a 4 x 3 factorial arrangement involving a control (0%), three cooked castor oil bean meal levels (10,15 and 20%) and three DL-methionine levels (0,0.25 and 0.5%). Each treaiment was replicated thrice with 5 birds each. Feed and water were supplied ad libitum from 42 to 70d of age. The results showed that above 15% CBM inclusion level, average daily feed intake (ADFI) and average daily weight gain (ADWG) were significantly (P<0.05) decreased. There were also significant reductions (P<0.05) in efficiencies of feed and protein utilization, and in apparent retention of dry matter (DM), nitrogen, ether extract (EE) and nitrogen-free extract (NFE). While packed cell volume was not significantly (P>0.05) affected by CBM or DL-methionine, haemoglobin concentration (Hb) was significantly (P<0.05) increased at 20% CBM level. Supplementation with DL-methionine improved (P<0.05) weight gain at the 15 and 20% levels of CBM inclusion; improved Hb and efficiencies of feed and protein utilization at the 20% level of CBM inclusion, improved nitrogen retention at the 0% level of CBM inclusion; improved EE retention at the O and 20% levels of CBM inclusion, and improved NFE retention at the 15% level of CBM inclusion. The results of this study indicate that processed CBM can be included in broiler finisher diet at 15% level with DL-methionine supplementation to obtain normal growth in broiler birds.

The effects of graded levels of dehulled-and-cooked castor oil bean (Ricinus communis, L) meal on the performance of broiler starters were studied. Castor oil bean seeds were dehulled-and-detoxified by cooking in two stages at 1000C for 50 minutes per cooking. Sixty 7-day old unsexed broiler starters (Anak strain) were randomly divided into four isocaloric (2.88 mcal of ME/kg) and randomized design (CRD). Each group was fed one of four isolaric (2.88 Mcal of ME/kg) and isonitrogen (24% crude protein) diets containing 0%(control), 10, 15, and 20% levels of dehulled and cooked castor oil bean meal( CBM), respectively for five weeks. There were no significant (P>0.05) differences between birds fed the control diet and those birds fed the 10% CBM diets in all the parameters measured with the exception of packed cell volume (PCV). Inclusion levels above 10% caused significant (P>0.05) caused reduction in average daily feed intake and daily weight gain. However, the reduction in feed conversion ratio and protein efficiency reatio became significant (P<0.05) only at 20% inclusion level. PCV was depressed (P<0.05) by all the iunclusion levels of CBM. Overall, the birds fed the 20% dehulled-and-cooked CBm had the worst performance. It as concluded dehulled-and-cooked CBM could be included at the levels 10 and 15% in the broiler starter diets without much adverse efffects on the performance of the broiler starters.

Sixty 7-week-old New Zealand White rabbits were randomly distributed into 5 equal experimental groups. The experimental rabbits were fed the tested diets till 14 weeks of age during summer season. The basal diet without feed additives (control; T1) and the other experimental diets were supplemented with enzymes at 0.5 g/kg (T2), organic acids at 1.0 g/kg (T3), Beta-pro at 0.2 g/kg (T4) or their combination (T5). The criteria of response were body weight, weight gain, feed consumption, feed conversion ratio, some blood constituents, carcass traits and economic efficiency. The obtained results can be summarized as follows: Positive effects of feed additives were observed on live body weight, daily weight gain and feed conversion of growing rabbits. There were no significant effects on blood parameters or carcass traits due to feed additives. It can be concluded that dietary Beta-pro (enzymes+probiotics) or a combination of enzymes, organic acids and Beta-pro at the tested levels can be used to improve the rabbit performance, with no adverse effects on carcass characteristics or blood parameters.

Production of Methyl 12-Hydroxystearate through the Hydrogenation Process of Castor Oil Esters. Castor oil (Ricinus communis L.) is one of renewable raw materials widely applied in various chemical industries. One of the castor oil derivatives is methyl 12-hydroxistearate, a methyl ester fatty acid which has been applied in various industries especially lubricants industry. This paper discusses the methyl ester production of methyl 12-hydroxystearate from castor oil via hydrogenation of ester of castor oil in a mini-pilot reactor. The purpose of this study is to determine the optimum operating condition of the hydrogenation process of the ricinoleic acid methyl ester by varying operating pressure and temperature. The operating pressure and temperature of the hydrogenation process were varied in the range of 2-4 bar and 150-210℃. The experimental results show that the hydrogenation process of ricinoleic acid methyl ester produces methyl-12-hydroxistearate with concentration up to 61.28%-wt and Iodine Value of 23.84. Higher operating temperature and pressure increase the conversion of methyl 12- hydroxistearate and reduce the iodine value. Further, the optimum operation condition for this process is at 210℃ and 4 bar. Increasing reaction time for about 3 hours results in a significant reduction of iodine value up to 9.82. Keywords: castor oil, hydrogenation, iodine number, methyl 12-hidroxystearate, methyl ester ricinoleic. Graphical Abstract

Daniellia Oliveri

The study was carried out to determine the effect of Daniellia oliveri leaf meal (DOLM) in complete diets on feed intake, digestibility, nitrogen utilization and growth of Savannah Brown goats in a 90-day trial using the completely randomized design. Thirty-six does, with an average initial weight of 10.66 kg, were randomly divided into four groups of similar body weight (BW) and allocated to one of the four complete diets with DOLM inclusion levels at 0%, 20%, 30% and 40% respectively. Intakes of dry matter (DM) and organic matter (OM), and cost/kg BW gain were higher (p<0.05) in the control diet than in the treatment diets. Intake of crude protein (CP) was higher (p<0.05) for the control diet compared to the 30 and 40% DOLM diets. Feed conversion ratio and faecal nitrogen excretion of animals on 20% DOLM diet were lower (p<0.05) than other diets. Final body weight, total weight gain and average daily weight gain were not (p>0.05) affected by the diets. Digestibility of DM and CP, and nitrogen balance of animals on 0 and 20% DOLM diets were higher than those on 30 and 40% DOLM. Digestibility of OM and crude fibre was lowest (p<0.05) for the control diet relative to other diets. Nitrogen intakes (NI) of 0 and 40% DOLM diets were lower (p<0.05) compared to those of 20 and 30% DOLM diets. Nitrogen absorbed (NA) and nitrogen retention (as % of NA) were marginal (p<0.05) for 30% DOLM diet relative to other diets Nitrogen retention (as % of NI) was highest and lowest (p<0.05) for 20%DOLM diet, and 30 and 40% DOLM diets respectively. The study shows that Daniellia oliveri leaf meal can be used up to 40% inclusion level to replace 100% of maize offal in the diet of Savannah Brown goats without adversely affecting the performance of the animals.

Abstract Castor (Ricinus communis L.) has been transformed from a wasteland colonizer to an important industrial oilseed crop. Its seed oil is one of the most sought-after vegetable oils because of its rich properties and variety of end-users. Castor is an ancient crop but its production now has been limited mainly to India, China and Brazil, for many reasons. Castor oil is a hot market commodity product. It has been recently recognized as an efficient feedstock for biodiesel production. Increasing demand world over for biofuel resources and many recently identified industrial uses of castor oil have escalated castor oil demand. Global demand for castor oil is rising constantly at 3-5% per annum. In the last decade, many countries have started making serious exploratory efforts at growing castor as there is a tremendous scope to establish castor as a supplementary crop production option to farmers and to provide significant returns on investment given high global demand for castor oil. In view of the increasing worldwide interest in castor oil, this review evaluates the global scenario of castor cultivation, exports and imports of castor oil, new interests in castor oil and genetic improvement in productivity. In addition, the current research challenges and priorities have been discussed in the review.
