Use of different zeolite percentages in it puts on weight of chickens broiler, 2. To establish the production costs, for each treatment and 3. To determine the food consumption, gain of weight, nutritious conversion and mortality. One works with 150 chickens broilers, in batteries from the birth until the 49 days of age. The same ones that were distributed in 15 homogeneous groups of 10 chickens each one. Considering 5 treatments according to the level of zeolite incorporation in the diet (Treatments 0, 1, 2, 3 and 4 zeolite %) with 3 repetitions each one. The experimental design was randomizado completely and the test of separation of averages was of Duncan, with significance level 0,05. The feeding consisted on a habitual commercial outline, the parameters that were investigated for each one of the portions were: gain of weight, mortality, production costs, food consumption and nutritious conversion, for that which the animals were weighed to the beginning and weekly until having concluded the rehearsal, of the results you reaches the following conclusions: The food consumption during the final phase was of 0% = 4,29; 1% = 4,17; 2% = 4,45; 3% =4,36; 4%= 4,03kg. The gain of weight average for animal was: 0%= 2,70; 1%= 2,55; 2%= 2,69; 3%= 2,52; 4%= 2,51kg. The nutritious conversion after the rehearsal was 0% = 2,26; 1% =2,37; 2%=2,35; 3%=2,31; 4%= 2.30, the biggest utility was obtained of the treatment 0%: with $1,01; it continues him 2%: with $0.90; then 4%: with $0.87; 1%: with $0.85 and 3%: with $0.69 dollars. As for mortality the percentages were: to the 0, 1 and 3 zeolite% = 6,66%; with 2% = 16,66% and to 4% = 0%. |
