Fifteen Landrace pigs were used to determine the effects of supplemental copper or kapok meal, or both on the characteristics of the depot fat. The pigs were allocated into five groups of 3 pigs each. The animals were fed diets as follows: (1) control diet 100%; (2) control diet plus 20 mg/kg copper; (3) control diet plus 200 mg/kg copper; (4) control diet plus 3% kapok meal; (5) control diet plus 200 mg/kg copper and 3% kapok meal. In addition, 100 mg/kg iron and 100 mg/kg zinc were supplemented to all the diets. The pigs were slaughtered at the same time after 8 weeks of feeding period at an average weight of 98.6 kg. The supplementation of 20 or 200 mg/kg dietary copper did not affect the fatty acid compositions, the iodine numbers, the melting points or the copper contents of the inner and outer layers of backfat and the perirenal fat from pigs. Supplementation of kapok meal significantly elevated the melting point, the content of C18:0 and the ratio of C18:0/C18:1 of the porcine fats and decreased the content of C16:1. There was no interaction noted between copper and kapok meal on the porcine fat characteristics. These results indicate that the swine diet supplemented up to 200 mg/kg copper with zinc and iron can be used in growing-finishing swine diets without affecting either porcine fat characteristics or hardening effect of kapok meal on porcine fat.

The bioremediation potential of crude oil by Polyporus sp. S133 pre-grown in wood meal was investigated in two separate experiment trials; liquid medium and soil. The effect of three nutrients (glucose, polypeptone, and wood meal), oxygen flow, and some absorbent on the efficiency of the process was also evaluated. Degradation of crude oil in soil was significantly increased with an addition of oxygen flow and some absorbent (kapok and pulp). The highest degradation rate of crude oil was 93% in the soil with an addition of 10% kapok. The present study clearly demonstrates that, if suitably developed, Polyporus sp. S133 could be used to remediate soil contaminated with crude oil.

This experiment was conducted to determine correlation between in vitro protein fractions and in situ protein degradation rate with major dairy protein sources(soybean meal, corn gluten meal, cotton seed meal, kapok seed meal and perilla meal). Five protein fractions were obtained according to the Cornell Net Carbohydate and Protein System(CNCPS), and in situ protein degradation rates were determined by technique using nylon bags incubated for 0, 4, 8, 12 and 24hrs in the rumen of three Holstein steers. Fraction A was highest in kapok seed meal(14.6%) and lowest in corn gluten meal(0.6%) (P<0.05). The highest B1, B2 and B3 fractions were contained in soybean meal(8.27%), cotton seed meal(74%), and perilla meal(40%), respectively. Corn gluten meal was very high in fraction C. In situ protein degradation rate of soybean meal was 98%, highest among five protein sources, and corn gluten meal had the lowest rate at 28%. Correlation analysis showed that easily soluble fractions of both methods, in situ protein degradation rate and digestible protein fractions, and in situ protein degradation rate minus “a” and fraction B2+B3 were highly correlated. These results indicate that in vitro protein fractionation can be used in the estimation of in situ protein degradation.

In this study, we attempted to find alternative materials to rice bran (Japonica in Korea) such as rice bran pellet (Indica in Pakistan), corn distillers dried grains with solubles, sesame oil meal, and kapok meal for bottle cultivation of Pleurotus eryngii. Among all treatments, the total carbon content of the mixed substrate was the highest in T1 and the total nitrogen content was the highest in T4. The C/N ratio of T2 was comparable to that of the control and was higher than that of other treatments. The diameter of the pileus was the largest in T1 and T2, and the length of the stipe was the largest in T1 and T2. The yield and bio-efficiency of the fruit body were higher in T2 than in the other treatments, and were similar to that of the control plot. Therefore, the findings of our study suggest that rice bran pellet (Indica in Pakistan) could be a suitable alternative to rice bran (Japonica in Korea) for the cultivation of P. eryngii.
