In a significant stride for poultry nutrition, researchers have delved into the effects of various phytase enzymes on broiler chicks, revealing insights that could reshape feeding practices in the industry. Led by Mojgan Salmanian from the Department of Animal and Poultry Nutrition at Gorgan University of Agricultural Science and Natural Resources, this study highlights the potential of using recombinant phytase enzymes derived from the probiotic yeast Saccharomyces boulardi.
The crux of the research centers on comparing two types of phytase enzymes: the traditional histidine phosphatase and the newer purple acid phosphatase sourced from the yeast. This is not just an academic exercise; the implications for commercial poultry farming are substantial. With the ability to enhance nutrient absorption from feed, these enzymes could lead to improved growth rates and feed efficiency, which are vital for a sector always on the lookout for cost-effective solutions.
Salmanian’s team conducted a meticulous experiment involving 336 one-day-old Hubbard Flex chicks, assessing their growth performance and intestinal health over a 41-day period. “Our findings suggest that while the growth performance between the two enzymes didn’t show significant differences, the intestinal morphology was notably affected,” Salmanian explained. This aspect is crucial as a healthier gut can lead to better nutrient absorption and overall bird health.
Interestingly, the study found that chicks fed a corn-based diet supplemented with purple acid phosphatase exhibited superior intestinal traits, such as increased villus surface area and length. These morphological advantages could translate into better feed conversion ratios, which means less feed is needed to achieve the same weight gain, a win-win for producers looking to maximize efficiency.
Moreover, the research indicates that using wheat as a feed base could enhance pellet strength, making it a viable alternative to corn. This could have broader implications for grain markets and feed formulation strategies, especially in regions where wheat is more readily available or cost-effective. “The strength of the pellets is important for reducing waste and ensuring that the birds receive the full nutritional benefit,” added Salmanian.
The findings also suggest that the recombinant phytase from Saccharomyces boulardi could stand toe-to-toe with commercial enzymes, offering poultry farmers a potentially safer and more effective option. The study, published in ‘پژوهشهای تولیدات دامی’ (Animal Production Research), emphasizes the need for continuous innovation in poultry feed practices.
As the agriculture sector grapples with rising feed costs and the need for sustainable practices, research like Salmanian’s could pave the way for new feeding strategies that not only enhance productivity but also promote animal welfare. The insights gained from this study may well inspire future developments in enzyme applications, ultimately benefiting both farmers and consumers.
