Evaluation of the effect of sodium butyrate addition to broilers diet on energy and protein digestibility, productive parameters and size of intestinal villi of animals

   

A total of 750 Cobb 400 one day old broiler chickens were used to evaluate the influence of sodium butyrate has on the animal performance, energy and protein digestibility of the diet and villi development. The animals followed a 3 phase feeding program with mash diets: starter, from 1 to 11 days (52% corn, 40% soya and 3% palm oil; EM 2950 kcal, 23% protein and 1.38% lysine), grower from 12 to 21 days (56% corn, 35% soya and 4% palm oil; EM 3050 kcal, 21% protein and 1.26% lysine) and finisher from 22 to 42 days (60% corn, 30% soya and 5% palm oil; 3150 kcal ME, 19% protein and 1.14% lysine).

 

The trial evaluated 3 treatments: control treatment (no additives), treatment BUT 0.5 (0.5 kg/t of 92% sodium butyrate) and treatment BUT 1 (1 kg/t of 92% sodium butyrate). Each treatment was replicated 10 times and each replicate consisted of 25 animals at the start of the test. The animals' weight and feed intake were controlled every two weeks (change of phase).

 

There were no statistically significant differences in the zootechnical parameters: at the end of the trial, the average daily gains were 47.7 g/day for control, 48.0 g/day for BUT 0.5 and 48.6 g/day for BUT 1 (P 0.47), average daily feed intake was 81.7 g/day for control, 81.6 g/day for BUT 0.5 and 83.6 g/day for BUT 1 (P 0.56) and feed conversion ratios were 1.71 for control, 1.72 for BUT 0.5 and 1.72 for BUT 1 (P 0.91). It is concluded that inclusion of butyrate in the diet improves the digestibility of energy and protein by increasing intestinal absorption surface.
