Betafin Improves Poultry Carcass Characteristics

 
Milan Hruby, Andrea Barratt and Janet Remus

 

  

With increasing amounts of poultry meat sold as premium priced cuts, improving the yield of these cuts, such as breast meat, is one option available to the producer to increase profitability. Improved poultry carcass characteristics such as lower fat content, higher percentage of breast yield and increased carcass yield in general, together with other factors such as meat tenderness, colour and juiciness, are factors which are becoming increasingly important to consumers, and consequently to meat packers and poultry integrators.

 

To meet consumer demand, breeding companies have been selecting for leaner strains of birds with higher carcass yields. To fully exploit the genetic potential of these birds, nutritionists have developed diets which are of higher nutritive value, both in terms of nutrient density and digestibility. Several nutrients, such as crude protein, essential amino acids and the amino acid to metabolisable energy ratio are known to affect carcass yield, by directly affecting protein synthesis. In addition, some feed supplements, such as betaine, have also been shown to improve these carcass characteristics. The following overview summarises some of the recent studies which have shown that Betafin (betaine, Finnfeeds) has a role in improving breast and carcass yield in broilers and turkeys.
