Research Note: Effect of dietary cottonseed meal and soybean oil concentration on digesta passage time and amino acids digestibility in roosters

Two experiments were conducted to study the effect of dietary cottonseed meal (CM) and soybean oil (SO) on passage time of digesta and standardized ileal digestibility (SID) of amino acids (AA). The experimental design was a 2 × 2 factorial arrangement evaluating the levels of CM (20 or 40 %) and SO...

description Two experiments were conducted to study the effect of dietary cottonseed meal (CM) and soybean oil (SO) on passage time of digesta and standardized ileal digestibility (SID) of amino acids (AA). The experimental design was a 2 × 2 factorial arrangement evaluating the levels of CM (20 or 40 %) and SO (0 or 10 %). Experiment 1 estimated the effect of CM and SO on the passage time of digesta. Twenty-five Chinese yellow-feathered roosters (BW = 2.61 ± 0.08 kg; 26-wk-old) were individually weighed and allocated to 5 diets in 5 randomized complete blocks by initial BW. Experimental diet 1 contained 20% CM and 0 SO, diet 2 contained 20% CM and 10% SO, diet 3 contained 40% CM and 0% SO, diet 4 contained 40% CM and 10% SO, and a nitrogen-free diet was also fed. Passage time through the total digestive tract was determined by time-relative cumulation of dry excreta. Experiment 2 estimated the effect of CM and SO on SID of AA in CM. Thirty Chinese yellow-feathered roosters (BW = 2.91 ± 0.05 kg; 26-wk-old) were allocated to the 5 experimental diets in 6 randomized complete blocks by initial BW to determine the SID of AA. Increasing CM concentration significantly reduced the time for 50% relative cumulation of dry excreta (P < 0.05). Adding 10% SO tended to increase the time for 50% relative cumulation of dry excreta (0.05 < P < 0.10) relative to diets without SO. Dietary CM and SO did not affect the SID of indispensable AA or dispensable AA of CM significantly, but increasing dietary CM tended to reduce the SID of Lys (0.05 < P < 0.10). Increasing SO tended to reduce the SID of Met (0.05 < P < 0.10). There were no significant interactive effects of SO and CM (P > 0.10). These results suggest passage time is increased with dietary SO, and reduced with dietary CM, but digestibility of AA in CM was not significantly affected by dietary CM and SO.
