Summary

The aim of this work was to validate a matrix value using an enzyme combination with phytase, amylase, xilanase and protease, in broilers diets, by economic evaluation. A total of 640 male Cobb broilers will be evaluated from 1 to 35 days post hatch. The birds will be assigned to 4 treatments, with 8 replicates of 20 animals each, distributed in a randomized experimental design. The feed will be provided in 2 phases as follow: Starter (1 to 10 days), Grower (11 to 35 days). A Positive Control diets will be formulated to fulfill the requirements for each phase. The Negative Control diets will be formulated considering the matrix value of the enzyme combination (phytase+ amylase+ xylanase+ protease) however without any enzyme complex added. The treatment 3 was the Treatment 1 (Positive Control) plus the enzyme combination and the treatment 4 was the treatment 2 (Negative Control) plus the enzyme combination. An economic evaluation was made of the gross margin based on the data production of broiler meat. The cost of production between treatments was considered only the fed. After calculating the gross margins of the treatments was made on a gross margin compared to the Positive Control. The treatments Negative Control without the enzyme complex and Positive Control with the enzymatic complex were 2.44 and 3.08% less profitable than the Positive Control. The Negative Control with the enzyme complex differed from the others and made production more efficient from the standpoint of economic 3.38% compared to the Positive Control.

INTRODUCTION

The use of additives in feed for broilers is increasing every day. Enzymes are the most commonly used in this segment, they are very effective in increasing nutrient availability to broilers and guarantees the farmer a lower cost feed formulations and also an improvement in rearing conditions.

Enzymes in the diet and improves the efficiency of poultry production by increasing the digesting products of low quality and reducing the loss of nutrients in the faeces as reductions in levels of energy, protein and amino acids in the formulation of diets for broilers (Torres et al., 2003).

This respect, it is feasible to reduce nutritional diet for broilers with the use of enzymes in feed. Thus, the objective of this study was to evaluate in economic performance of broilers from 1 to 35 days of age fed diets with enzymes and reduced nutritional status.

MATERIAL AND METHODS

A total of 640 male Cobb broilers will be evaluated from 1 to 35 days post hatch. The birds will be assigned to 4 treatments, with 8 replicates of 20 animals each, distributed in a randomized experimental design. The feed will be provided in 3 phases as follow: Starter (1 to 10 days) and Grower (11 to 35 days).

A Positive Control (PC) diets will be formulated to fulfill the requirements for each phase. The Negative Control (NC) diets will be formulated considering the matrix value of the enzyme combination (Phytase+ Amylase+ Xylanase+ Protease) however without any enzyme complex added.

The treatment 3 will be the Treatment 1 (Positive Control) plus the enzyme combination (PC-E) and the treatment 4 will be the treatment 2 (Negative Control) plus the enzyme combination (NC-E). Enzyme Combination: 200g ProAct + 400g Ronozyme A + 100g Ronozyme WX + 20g HiPhos (M) per metric ton. This enzyme combination will be provided mixed, ready to use.

The feed intake was calculated by the total feed intake of each treatment at phase. The broiler production was determined by multiplying the number of broilers at 35 days of age by the weight gain of these birds. The gross income considers just the price of broiler, because it was killing the 35-day-old chickens. The treatments were compared by the relative gross margin.

RESULTS AND DISCUSSION

The treatments were important in changing the economic performance of broilers (Table 1).

The most varied among treatments were the cost of fed, making extra income to be influenced. The cost of fed on period, from 1 to 35 days of age, was higher for Positive Control plus enzymes (PC-E), and the lowest was the Negative Control (NC).

The broiler production was higher in treatment with nutritional reduction and plus enzymes (NC-E), and even having a greater cost of fed in relation to the Positive Control had a higher gross income. Thus, the greater broiler production in phase was able to recover the largest investment with the feeding of broilers, paying the investment.

CONCLUSION

The enzyme complex improves the gross margin, with 3.38% up to Positive Control.
