Effect of Coconut Meal on Coturnix Quail and of Coconut Meal and Coconut Oil on Performance, Carcass Measurements and Fat Composition in Swine¹

University of Hawaii, Honolulu 96822

Abstract

One trial involving 150 quail (Coturnix c. japonica) and two trials involving a total of 94 pigs were conducted to study the effect of the use of coconut meal and coconut oil in diets for these animals. The trial with quail was designed to study the effect on rate and efficiency of gain of including 20 or 40% coconut meal with and without added lysine in diets containing two energy sources. Trial 1 with pigs was designed to study the effects of 0, 10, 20 and 40% coconut meal and 0 and 10% coconut oil on pig performance, carcass leanness, physical composition of the ham and fatty acid composition of backfat. The second swine trial was designed to determine if increasing the protein or lysine levels would overcome the depressing effect of 20 or 40% coconut meal when included in corn-soybean meal diets. Pigs fed diets containing 0, 10, 20 and 40% coconut meal gained 0.76, 0.74, 0.65 and 0.46 kg daily and required 2.51, 2.68, 2.75 and 3.27 kg feed/kg gain, respectively. Loin-eye area and ham weight declined with increasing increments of coconut meal. Increasing protein and lysine levels did not overcome the depression in gain or muscle development due to coconut meal. It can be concluded that some factor other than a lack of adequate level of protein or lysine caused the depressing effect of coconut meal.

Coconut oil and coconut meal additions resulted in relative increases in the lower saturated fatty acids in the backfat. When coconut meal was fed, there was a decrease in stearic acid with little change in oleic acid. This effect was opposite to that of feeding coconut oil.
