Evaluar el efecto de tres niveles de fitasa en dietas de lechones

SUMMARY The experimental work was carried out in the swine farm of Mr. Pablo Moreno in the San Joaquin enclosure of the Babahoyo-Montalvo road. Duration of the experimental work was 28 days. The objective of this work was to evaluate the effect of three doses of phytase on weaned pigs. A completely randomized design "D.C.A" was used with three treatments and eight replicates with eight pigs per treatment and one for each replicate, thus forming eight experimental units with a total of 24 pigs. Testing of the treatments was performed using the Tuckey test (p˂0.05), using the statistical program infoStat version 2012. Three phytase levels were evaluated (T0 = 0g, T1 = 200g, T2 = 400g). The variables studied were: Weekly average weight, weekly food consumption and feed efficiency. In the samples taken of average weekly weight, no statistical difference (p0.05) was found between the means of the treatments. Treatment T1 (200g) 26.89Kg. (0.0g) with weight of 26.19kg and T2 (400g) with weight of 25.57kg. In the parameters of food consumption, the results are obtained, proving that the food consumption variable does show significant differences (p˂0.05). Treatment T2 (400g) obtained weights of 11.54kg (c), being greater than T1 (200g) with 11.44kg (b) and T0 (0,0g) with 10,65kg (a). In the food-efficiency parameters, a statistical difference (p0.05) was recorded, with T2 (400g) with 3.31% (c), superior to treatment T1 (200g) with 2.86% (b), and To the T0 treatment (0.0g) with 2.73% (a).
