Roll shell configuration and feed ingredients
Dear Mark,There are many different designs and configurations of roller shells. You should check with the pellet mill supplier what designs and combinations are available and the experience they have in regard to gripping, even wear or smooth operation without vibrations as well as what products are best pelletized.If you mean roll slippage by skidding; there are multiple reasons for this. Fo ...

Starch gelatination in the conditioner and extruder
Dear Dr. John Sinclair, As you have mentioned it can be measured by enzymetical methods. to do so you can easily use a Megazyme Kit called Starch Damage kit. I have already used it amd got a reasonable results for measuring starch gelatinisation. good luck

Secondary Infection after Infectious Bronchitis, Became more of an issue than the IB itself
There is no sigle strain IB vaccine to protect variants present in your area. However, Ma5 from MSD is capable of providing protection against different strains. Spraying the vaccine at hatchery will provide better protection. Mycoplasma control at breeder level (Tiamulin at 25 mg per kg for 2days every 28 days in laying) produce Mycoplasma free chicks. This will reduce E.coli load in broiler Chic ...

Weaning piglets without antibiotics

60-80% of antibiotics are used for digestive problems. The period after weaning is known for its regular antibiotic application and could be  a perfect target for an important step in  antibiotic reduction. Restrictive use of antibiotics is no longer an exception, but a global target. Besides the EU, also the US and Asia, started to implement changes. To restrict antibiotic us ...

Extrusion Cooking Systems for Feed Production. Joe Kearns (Wenger)
Radmilo Colovic All is good. The tuna feeds worked on while at Wenger were of the semi moist style. 3 feed streams, one of standard feed ingredients at 11- 12% moisture. The 2nd stream or the ground up pilchards approx. 65% moisture, and the liquid stream of humectants. All by computer control with flow meters etc to get the percent's correct. We were really up in moisture near 40%. 1/2 the formul ...

Extrusion Cooking Systems for Feed Production. Joe Kearns (Wenger)
Dear Joe,Hope you are doing great.Thank you for opening a very interesting topic.Can you share some more details on the trials you have performed on the tuna feed production? What was the proximate moisture content in the feeding section before steam and slurry addition and what was calculated moisture content in the barrel (counting the steam and slurry part as well)? Did you use glycerol as the ...

Roll shell configuration and feed ingredients
I assume you are talking about roll shells for pellet mills.There are different configurations possible with roll shells.In general; Dimpled rolls have a better pressure distribution in the die but the gripping action is moderate.In general, the wear is more even in the die due to the fact that the product cannot escape to the side of the roll. Used for regular feed products with limited slippage ...

Aliphos: a global player in the feed phosphates industry
Both forms of phosphorus- inorganic like Aliphos and organic from plants are important. Organic (from phytates ) form is now highly "extracted" by using phytase. It gives quite important dose of dietary phosphorus we need in feeds. But usually is not enough and we add usually few kg/t feed inorganic phosphorus (eg.broiler feed). Different situation we have in countries using MBM or even just bone ...

Fowl Cholera
Fowl cholera presents in various degrees. Acute cholera causes rapid death. Chronic cholera can take weeks to cause death. Typical carriers are rodents. A good systematic rodent control program will help reduce exposure. Fowl cholera is caused by Pasteurella multocida. It is not transmitted via the eggs, so your husband can continue to consume eggs. I would not kill the flock. Transmission is usua ...

Control of Coccidiosis and Necrotic Enteritis - Greg Mathis
Emmanuel Nwaotule Dear Emmanuel, thank you for your message. Although this discussion refers to two diseases, that is, coccidiosis and necrotic enteritis, there are some aspects to be taken into account: coccidiosis is one of the leading factors to necrotic enteritis but necrotic enteritis is not a leading factor to coccidiosis. That means that a good control of coccidiosis will diminish necrot ...
