Enzymes have been used in livestock for many years, but are increasingly being used in corn feed for diet supplementation for poultry. The enzyme complex used in the experiment had 2000 Units of activity/gram of enzyme amylase, 40,000 IJ/g protease, and 20,000 U/g xylanase. These supplements were grinded into 1. 5 mm bits and met levels of nutrients appropriate for the pigs. Experiment 1 had a meal corn control diet and two experimental
One important note is that the feed was not limited and neither was water. 6 pigs each from control and 150 supplemental were killed after two hours of eating. In experiment 2, 6 crossbred barrows outfitted with T-cannulas (thin tubes for insertion/extraction of agents), ate commercially twice daily in increasing amounts. After 12 days, they were given the “3 treatments”. Each treatment was 7 days. In experiment 1, pigs fed supplements with 150 ppm increased weight (p equaled . 09) compared to the control. The results indicate that the enzyme mush improved the pigs’ body weight gain, energy, and dry xcretions of the pigs.
The dry matter suggests that the blend affected nutrient digestibility the most by breaking the plant cell wall and subsequently releasing the nutrients in the cell wall for the pig. Viscosity of stomach matter also increased for those fed with supplements as the enzymes may have caused insoluble matter to break down into short chain polymers, increasing solubility. The enzyme complex improved acticity in the weaned pigs through this nutrient digestibility and change occurring to the bacteria of the large intestine. Windows on Research By sferraol
