Rama Prasad Chakraborty Yes, absolutely, I also appreciate your opinion. However, unfortunately many in the industry have not explored the advantages of full-fat soybeans (FFSB) not only from the energy content standpoint of view, but also, as I wrote, from the opportunity to considerably decrease residual trypsin inhibitors to almost zero by proper processing. It is not easy to overprocess FFSB ...

Dear Dr. Koushik De. I find interesting your discussion on trypsin inhibitors and their role as antinutritional factors in broiler nutrition. It would be nice however, if you add a list of all the literature cited and provide credit where credit is due. Havenstein et al. (2003) didn't discuss trypsin inhibitors in their comparison of the 1957 and 2001 genetics, the slide that you have in your pape ...

The purpose of a minimum ventilation system is to bring in small amounts of cold fresh air into a house and to warm it as much as possible before it moves down to floor level so as not to chill the birds and to maximize the litter drying potential of the incoming air. Traditionally, poultry producers have utilized a “negative pressure” minimum ventilation system. In a negative pressure ...

Gerardo RosalesDo you measure the humidity? Ideally it would be around 60% if it is much higher the minimum ventilation rate should be increased regardless of the calculated value.

Gerardo Rosales In general the shorter the timer cycle the more consistent the house temperature and air quality will be. For instance, operating minimum ventilation fans 1 minute out of 5 will produce less temperature variation and air quality variation than operating them 2 minutes of of 10. Since the house temperature varies less sometimes you will save fuel. We typically do not use a time ...

Hi Dr, I got a question for you, if you don't mind, could you tell me why the minimum ventilation cycles are always based on a 5 minutes time, I mean every time I use the calculator the time on and off is always based in 5 minutes. and how can it affect the system if we have cycles of less and more than five minutes. The president of the poultry company always change the cycles to less than 5 minu ...

1 Introduction Amino acids (AAs) are the building blocks of protein, which is the major dry matter component of growth in chickens and their eggs (Baker 2009). As foods for humans, poultry and eggs provide high-quality protein that contains sufficient amounts and proper ratios of AAs, therefore playing an important role in the growth, development, and health of humans (McNeill et al. 2017; R& ...

As nutritionists we must remember the methionine cycle and transulfuration pathway to cysteine should be considered as just that, a cycle, dependent on or including choline, betaine and certain of the b vitamins. Failure to include any one component could result in the cycle not being optimized resulting in homocysteine buildup, limiting TSAA supply and an under-estimation of the TSAA requirement.

Dear George Entz, Thank you for your message!I suppose that you mean as absolut %. First I want to highlight that it is possible to lower the crude protein only when we are adding the building blocks of the crude proteins, meaning the amino acids; the synthetic amino acids need to be supplied and the dM+C level and d.M+C/ d.Lysin ratio need to be kept at the same level. In our trial, we lowered th ...

 A balanced microbiota is vital for the intestine to have good function, in addition to gut integrity. The microbiota is formed by non-pathogenic microorganisms, which are of key importance for the metabolism and the absorption of nutrients and other compounds consumed by animals. A healthy microbiota has a high diversity of microbial genera in perfect balance, allowing an increase in the met ...
