In a follow up experiment with the same team at USDA Wisconsin, a Negative Control treatment was also included to allow a better assessment of what part of the improvements in N-efficiency were simply due to reducing N intake and what part were due to an improvement in performance through amino acid balancing.

Yes, the genetic potential for milk yield and for components is different for the different breeds. Holsteins cows have lower milk fat and milk protein than Jersey cows for example. The requirement for nutrients depends on the breed (and within breed on milk yield, milk components, DIM and so on).
Optimizing rations for nutrients means to optimize the nutrient supply from fee ...

Introduction. Organic selenium (OSe) has an advantage in reducing oxidative stress in comparison to inorganic forms and incorporates into skeletal muscles, kidney, liver, and gastrointestinal mucosa proteins as selenomethionine and selenocysteine. It is an essential micronutrient for fish (Martinez-Alvarez et al., 2005). Yeast cell wall has been proven as an immunostimulant and health improver for ...

In response to Dr. Marchenkov. Sorry, but I disagree very strongly! Animal feed mixing is very predominantly a dry mixing process. As soon as you add small quantities of ANY liquid into this dry mix you start to get "balling" where dry particles aglomerate. This immediately reduces homogeneity. As well as the basic physical mixing problems of adding liquids to a solid mix, we have the additional p ...

Ricardo Hume Dear Ricardo, 100% agree with your opinion. CV 5% is easy to reach, because if we will spray methionine into the mixer, during the mixing process, feed mix becomes to be (theoretically, if mixer is well adjusted) 100% homogenic, in splite of different size and specific density of ingredients. After the end of mixing process, during feed transportation, stratification is possible, but ...

Marc Perel Thank you Marc for your comments.I totally agree with you that a dosing accuracy of 1% is excellent. This means that when you add 4kg of a product / ton you will find samples between 3.960 kg and 4.040 kg/ton. That range represents a CV = 0.5%.Best regards, Ricardo

Dear Ricardo Hume ,Please let me comment your last message to avoid any confusion:On one hand, we speak about homogeneity of repartition of an additive in a batch of feed, where the CV translates the variability between N samples taken from a same batch. I mentioned that a CV of 10% is acceptable, you prefer to say 5%, it is OK, I will not comment further.On the other hand, you mention "...a dosag ...
