The objective of this study was to determine the effect of dietary flaxseed on pig growth performance and fatty acid composition of pork. Eighty-four gills weighing approximately 85㎏ were fed diets containing 0 (control diet) or 8% flaxseed for the final 28 days prior to slaughter. Flaxseed treatment did not affect any growth performance of finishing pips(P$gt;0.1). However, pigs fed flaxseed diet had significantly(P$lt;0.05) higher amounts of omega-3 fatty acid in loin and belly and resulted in a reduction in the ratio of omega-6 to omega-3 fatty acid from 12:1 to 4.5:1(P$lt;0.05).

A total of 252 three days old broiler chicks were used in a feeding trial and a metabolic study. Birds were fed DCP, three levels of phytic acid and three levels of Ca-Mg-phytate to investigate the effects of phosphorus supplementation on the growing preformance of broiler chicks and nutrient utilization. The results obtained are summarized as follows; 1. Adding incremental levels of phytic acid to basal diet improved body weight gain and the improvement was greater in magnitude than adding DCP or Ca-Mg-phytate. 2. Feeding Ca-Mg-phytate improved body wt. gain and supplemental effect was similar to that of DCP. 3. No significant differences in mortality were noticed in all treatment groups. 4. Phosphorus levels and sources did not influence DM digestibility, but chicks fed phytic acid digested crude protein better than those fed other diets. 5. Apparent absorbability of Ca in Ca-Mg-phytate was higher than other sources, but when apparent amount of absorbed Ca was calculated, phytic acid was better than others. 6. Higher absorption of Ca and P generally resulted in improved growth performance of broiler chicks. It may be concluded from present results that supplementary phytic acid can improve the growth performance of chicks, and phytate may have some, although less, supplemental effect. Although the effects of DCP and Ca-Mg-Phytate supplementation were not significantly different, this may not necessarily indicate that phytate phosphorus was well utilized by chicks. The results should be interpreted in such a way that DCP used in the present study was poorly utilized. The exact reason is not apparent, but DCP used in present study might be anhydrous form, which is generally regarded as poor source of phosphorus.
