The Effect of ButiPEARL™ Tested on Broiler Performance in a Hungarian Broiler Farm
Fatty Acids and Their Role in Animal Growth and Development
The role of short chain fatty acids such as butyric acid to support the growth and development of the intestinal epithelium is very well known. This leads to an improvement in the growth performance of the birds. The broiler producer was interested in better results and has some experience in field trial implementation in farm conditions to generate reliable data. After several discussions about the topic we agreed to test ButiPEARL in one of his broiler farms.
The farmer has around 260.000 broilers per cycle in three farms. One farm is an old building with around 20.000 birds per cycle, the other is around 15 years old with 80.0000 broilers per cycle and few years ago they built a new farm with 160.000 birds per cycle. They have their own feedmill for mash feed production.
We had a chance to perform two consecutive trials in the same farm with around 80.000 broilers per cycle in five poultry houses. The first trial was made in January and February 2016 (Table 1). and the second was made in May and June 2016 (Table 2). In the first study three houses were set-up as the control group while the two other houses were taken as treatment. In the second trial the layout was reversed: two houses formed the control group and the other three houses were the treatment group. In each broiler house day-old mixed sex Ross 308 birds were placed. The feeding program was similar for the control and the treatment group; the only difference was that the treatment group had 300 g/ton of ButiPEARL added to the feed.
Results of the Effect of ButiPearl™
The results from the first trial can be seen in Table 1.
|Day old chickens (number)||49518||33062|
|Average weight at 42 days (gram)||2600||2690|
|Total feed consumed (kg)||209441||145487|
The results from the second trial can be seen in Table 2.
|Day old chickens' weight (gram)||44.5||44.5|
|Day old chickens (number)||34670||51996|
|Average weight at 42 days (gram)||2645||2675|
|Total feed consumed (kg)||149550||227423|
At the end of the cycles the average weight and the FCR were calculated based on the live weight delivered to the slaughterhouse and the total amount of feed consumed per treatment. The mortality was calculated comparing the total number of day old chickens placed and the total number of animals slaughtered per group.
Conclusion of the ButiPearl™ Study
In both trials there was improvement in body weight, a reduction of mortality and improved EPEF in the ButiPEARL group. Taking into account the cost of ButiPEARL , the average weight and mortality improvement, the total cost per kg live weight was lower in the ButiPEARL group than in the control group. For 100,000 birds this benefit is 6500 € per cycle which would mean a return on investment above 10 to 1. Because of these results, the farmer has decided to use ButiPEARL on all his farms.
