In this episode of Let's Squawk About It, Frank Ivey (Feed2Gain, LLC) talks to Andy Vance (PSA Executive Director) about a type of model used to determine matrix values, and how this model helps understand the impacts of feed changes before they are implemented.
Yes I will like to discuss the topic, "Matrix Mathematics in Broiler Production" We are developing the framework for expansion of production in my country.....Trinidad and Tobago, West Indies/Caribbean....it will be interesting to hear some of the concepts captured in this dialog.
As we press for more production, knowing the effects of our diet changes become more important. Our website, www.feed2gain.com has large and small programs for this. Go there to get more information or email me at firstname.lastname@example.org
Luis Fernando Vergamini Luna Professor Luna, averaging across a week of flocks or across study results will give a better calibration of our predictive calculations than using a single data set. If one is trying to determine impacts of an ingredient like an enzyme on the ingredients fed, a strong average data is needed.
I have one confusion: In the slide - example of mathematics on ingredients - Why you have considered 2% increased value (3319) of 1% increase (3254) instead of initial value (3222) for energy (Kcal/kg) calculation of wheat? Same calculation was done for energy of Soybean meal as well.
Dr. Yogesh Jadhav - you are correct. The math in my excel sheet was not right. If one percent of 3200 is 32 the 2 percent is 64. So the energy of wheat is increased to about 3286. Fortunately, the real analysis was conducted by a well tested program and the spreadsheet was supposed to help understand the process. Thank you for your very sharp eye and intelligence. We will try to do better.
