Litter management is a cornerstone of sustainable poultry production, directly impacting bird health, environmental safety, and community acceptance. Among the many challenges faced by poultry producers, fly infestation and persistent odour remain the most difficult to control. These issues not only affect farm hygiene but also pose risks of disease transmission, regulatory scrutiny, and strained ...

1. IntroductionPast reviews describe recent progress and future perspectives on the use of next-generation sequencing (NGS) in veterinary medicine. Key advances in mammalian NGS-based diagnostics include the adoption of different types of sequencing platforms and the development of specific applications of NGS for the different mammalian hosts common for human and veterinary medicine. These advanc ...

Good evening Dr Leeson.I have a question regarding broilers.I see in your article that for fully feathered layers the ideal temperature is 26 degrees C.What would the ideal temperature be for fully feathered broiler grown to 32 days taking humidity into consideration?Most broiler handbooks and articles says between 21 and 23 degrees.

I. INTRODUCTIONThe digestive dynamics of starch and protein are considered pivotal to broiler performance (Liu and Selle, 2015). Moreover, it was proposed that the rates of starch digestion and glucose absorption exceed the rates of protein digestion and amino acid absorption and this asynchrony in digestive dynamics compromises the performance of broiler chickens. If so, it follows that the provi ...

@Mangalmurti PathakIf analyzing substrates every time is impractical, so relying on average feed ingredient values from specific regions is a reasonable approach. The challenge of enzyme activity analysis is another hurdle since methods vary by supplier.But i think that the protein and amino acids provided by enzymes are not the same as calories.So they contribute primarily to growth, maintenance, ...

Dear Piotr, thank you very much for your point of view. It helps me use enzymes correctly, depending on the available substrates contained in the feed. I think that attention should also be paid to the methods of feed enzymes application, which have historically been used in different countries, this is 1) "over the top" of complete feed (for maximum absorption of nutrients) and also 2) "down spec ...

Thanks for the great topic and content. Some doubts arise during the paper reading, it would be better to increase CP digestibility by reducing the antinutritional and allergenics, using ingredients like SPC (Soybean Protein Concentrate), or decrease CP by using "pure AA" to meet the regular requirements.A second question, regarding soluble fiber, would be better to reduce soluble fiber or take th ...

ABOUT MATRICES OF FEED ENZYME PREPARATIONS (translated from Russian). The feed contains known nutrients, the need for which has been established, so their concentration in feed is constantly monitored. However, they completely ignore the fact that they are present in the raw materials not in their pure form, but as part of complex structures. Scientific evidence points to the importance of the st ...

Abstract. The concept of a "feed enzyme matrix" has become widespread over the past 10 years. It is used to quantify the increase in nutrient utilization of a feed by the action of feed enzymes.The factors that change the matrix values of enzymes are given. Due to the impossibility of substantiating stable values of matrices, in official instructions the values of matrices are virtual, therefore, ...

Hi dr. Piotr Stanislaski When incorporating enzymes into poultry nutrition, several common mistakes can undermine their effectiveness and economic benefits. Here's a structured overview of these pitfalls: 1. Incorrect Enzyme Selection.- Substrate Mismatch: Using enzymes not tailored to the feed's composition (e.g., neglecting xylanase for wheat-based diets rich in NSPs).- Phytase misapplication. ...
