Mike gave essentially a very concise response. Trace mineral addition is affected by the form of mineral added and also the amount and strength of the various inhibiting products contained in the feed. Most "nutrient requirements" are determined under fairly controlled conditions with most of the variables of feeding controlled. This is what we attempt to copy in our controlled feeding programs ...

It is necessary to know and have experience on the specific pelleting equipment and to know what the feeding program requires to understand the specific requirements for quality pellets. This is demonstrated by the different answers already given for the "best" conditioning. Ration formulation, grinding processes, amount of handling the pellet goes through, the climate it is processed in, etc. w ...

I intended to add that it may be more efficient to evaluate what your machine can do efficiently to process the soybeans than to ask it to do something for which it is not intended. Quite often, working to produce the best product available from our equipment is still preferential to not working to improve the feeding value of the original grain or product we need to work with. That is where you h ...

We have a large number of "extruders" available on a world-wide basis. Many of these were developed for a specific use/product and will not work to provide products drastically different from the original purpose. That does not mean the extruder described is not acceptable for its intended purpose but was simply not designed to do a different process. I agree with Dr. Albin that the conditions ...

As pointed out in some earlier discussions, the use of supplemental by-pass amino acids is economically justified either to promote additional milk production or to allow the use of more economical sources of supplemental protein (amino acids). My exerience is that we usually are more economical in working first with locally available feedstuffs than starting to add the more expensive by-pass amin ...

A very good piece of work discussing alternative feed ingredients. The results are very similar to field work I have done regarding use of cull beans and/or chick peas in cattle diets. The comments about some negative effects also reflect what I have seen if inclusion levels or total amount of the beans/peas are pushed too high. Maximum acceptable levels are usually reached before the economica ...

Organic farming--either crops or animal is basically not a feasible way for farmers with limited access to capital or inputs to operate. The ability to get "organic certified" inputs in remote or primitive systems is economically impossible and the ability to source the inputs is unfeasible. Producers with limited resources must proceed in a way that allows them to maximize the resources available ...

A typical Sniffen article--well written, concise and very usable! We all need to look at the overall efficiencies described in this article. A major shift in the thought process of the nutritionist has to be increasing financial return instead of working to get maximum production.In reference to the note from Helen Ajayi, one of the major problems with animal production in the developing regions i ...

Introduction    There is increasing pressure at federal, state and local levels about nutrient waste and pollution relative to N, P, CH4 and CO2 discharges from the animal industry. Large animal operations have come under more intense scrutiny than small animal operations, with CAFO regulations being put in place.      This has put increasing pressure on producers and ...

Basically, the use of various ingredients to supply the most cost-efficient supply of nutrients to meet the requirements of the animal being fed is the goal of ration formulation. There are few magic ingredients. Also, there is no single processing system that always provides the best ingredient. As some of the discussions indicate, full fat soy often meets energy requirements before balancing AA ...
