Manual mixing: This method is the main means of mixing feeds when raising chickens. When mixing, be careful and patient, prevent some trace components from pile up, agglomerate, and uneven mixing, which will affect the feeding effect.
Special attention should be paid to hand-mixing, which is a small amount of ingredients that are small in the diet but can seriously affect the feeding effect, such as salt and various additives. If the mixing is uneven, the lighter affects the feeding effect, and in severe cases, the chickens may cause disease, poisoning, and even death. For such trace components, it should be fully pulverized at the time of mixing, and there should be no agglomeration. The chunks should not be evenly mixed, and poisoning may occur after being eaten by the chicken.
Secondly, due to the small amount of such ingredients, it is not possible to directly add to the bulk feed for mixing, but should be pre-mixed. The method is as follows: take 10% to 20% of the concentrate (preferably a large proportion of energy feed, such as corn, wheat bran, etc.) as a carrier, and stack it again, and press the latter feed on the feed that was put down one by one. , that is, always put on the top of the feed, so that the feed flows around the center point into a conical shape, so that all kinds of feeds have the opportunity to mix.
This is repeated 3 to 4 times to achieve the purpose of uniform mixing, and the premix is â€‹â€‹prepared. Finally, the premix is â€‹â€‹added to the whole feed, and the mixture is mixed 3 to 4 times in the same manner to achieve the purpose.
When mixing by hand, it is only through such multi-level grading and mixing that the quality of the ration can be ensured, and the method of turning or stirring the feed in situ is not preferable.
Disinfection efficacy testing is usually done with planktonic cells or more recently, biofilms. While disinfectants are much less effective against biofilms compared to planktonic cells, questions regarding the disinfection tolerance of detached biofilm clusters remain largely unanswered. Burkholderia cepacia and Pseudomonas aeruginosa were grown in chemostats and biofilm tubing reactors, with the tubing reactor serving as a source of detached biofilm clusters. Chlorine dioxide susceptibility was assessed for B. cepacia and P. aeruginosa in these three sample types as monocultures and binary cultures. Similar doses of chlorine dioxide inactivated samples of chemostat and tubing reactor effluent and no statistically significant difference between the log(10) reductions was found. This contrasts with chlorine, shown previously to be generally less effective against detached biofilm particles. Biofilms were more tolerant and required chlorine dioxide doses ten times higher than chemostat and tubing reactor effluent samples. A second species was advantageous in all sample types and resulted in lower log(10) reductions when compared to the single species cultures, suggesting a beneficial interaction of the species.
