1 Feed Crushing Particle Size and Uniformity FG4 China Feed Industry Information Network – Based on Feed, Serving Animal Husbandry
1.1 Crushing Particle Size According to reports, weaning piglet diet When the particle size is reduced from 900 mu; m to 500 mu; m, the increase in the cost of diet is increased, which is less than the compensation generated by the feed conversion. Growing pig diet in corn crushing particle size at 509 MU; M ~ 1026 MU; M change, there is no significant impact on the daily gain of pigs; however, with the decrease in particle size, the feed conversion is improved to make the production performance of the best. The range of 509 mu; m ~ 645 mu; m. The corn crushing grain size in fatty pig diet is 400 mu; M ~ 1200 Mu; M, the particle size is reduced by 100 mu; M, the feed conversion increases by 1.3%. Corn pulverization particle size from 1200 mu; m minus to 400 mu; M The content of dry matter and nitrogen is reduced by 21% and 31%, respectively. Made in simple diet in corn particle size from 1000 mu; m drop to 500 mu; M Suitable particle size of 0 to 14 days and 14d ~ 35D feed after weaning is 300 mu; M and 500 MU; M; growth fatty pig and sow are 500 mu; M ~ 600 mu; M and 400 M ~ 600 mu; m.

1.2 The uniformity of the pulverized pulverized pulverizer is high. The conversion rate and growth rate of the wheat roller pulverizer are higher than the hammer pulverizer. When the maize is uniform, the production performance of fatty pigs is not affected, the digestible rate of diet, nitrogen and total digestion is increased, and the amount of dry matter is reduced in the dry matter of the manure; the corn is pulverized with roller crusher, and is more hammer The pulverizer can improve the nutrient digestibility rate in the diet, reducing the amount of dry matter from the dry matter in the dung and 12% of the discharge amount of nitrogen.

FG4 China Feed Industry Information Network – Best Feed, Service According to reports, when the coefficient of mixed uniformity variation of piglet diet was reduced from 106.5% to 12.3%, the daily gain and feed conversion increased by 32.5% and 19.2%, respectively; while fatty pig When the coefficient of diet is reduced from 53.8% to 14.8%, the production performance has no significant improvement. Therefore, the impact of dietary mixing uniformity on the young animal and the food-free price diet is large. Therefore, piglet diet is mixedThe appropriate variation coefficient of the homogenization is 12%; the mixed uniformity of fat feed pigment is a minimum of 15%.

Since the particles have many advantages from the powder, it is widely used in weaning piglets. Differential soybean flour granules have reduced their trypsin inhibitory factor content. Favrating the fatty pig and sorghum powder, resulting in the feed conversion of the particulate material, the total apparent digestibility and the nitrogen digestion rate is significantly higher than the powder, and there is no significant difference in weight. It has been reported that the pigment of the pigs in the 5-day-old feeding granules and the conversion rate and feed conversion are increased by 25% and 36%, and the particle diameter (2mm ~ 12mm) does not affect the growth of pigs; in 0 ~ 29 days, the pig daily weight and feed conversion and feed conversion rate are highest during the age of 29 days; the growth rate of pigs in 29 days-old ~ fertilizer period is not affected by the feed morphology, but the feed conversion rate of the particulate material is superior. Powder. There is also a report, when feeding piglets is sieved, the feed conversion rate is more than 4.5% higher than the particles of 10% or 30% fine powder; fertilizer pigs are prepared, and the pellets are proportional to the fine powder. 0 increased to 60%, the feed conversion rate decreased, the daily gain and nitrogen digestibility and the thickness of the thickness were significantly different. FG4 China Feed Industry Information Network – Based on Feed, Service Animal Husbandry Although the granulation is advantageous, it is adjacent to the yellow alcohol, vitamin K, ascorbic acid, carotene, vitamin E, and thiamine pair Granulation is sensitive. Studies have shown that the granulation temperature of 75 ¡ã C and 95 ¡ã C can make the activity of beta;-glucanase reduction by 40% and 70%, more than 110 ¡ã C, beta;-glucanase and cellulase activity are all lost. When the granulation temperature was 79 ¡ã C, the activation of phytase was reduced by 45.8%, and at 80 ¡ã C, 87.5%, and the activity loss was large.

The expansion and extrusion puffing have a short period of time, high temperature and high pressure. The expanded material has better admissibility and higher utilization than particles. Puffed processing is more effective than granulation in terms of control Salmonella. FG4 China Feed Industry Information Network – Based on Feed, Serving Animal Husbandry When the soybean is expanded, it does not affect the lysine content, significantly reducing trypsin inhibitory factor content and protein discrete index . In fertilizer pig diet based on corn, sorghum or wheat coarse powder, nutrient digestibility can be processed due to expansion.It is improved, but in the diet based on wheat, the digestibility of nutrients is not improved due to expansion; the frozen fiber content is higher than that of corn, the value is lower than the sorghum of corn, and after the expansion The degree of nutritional value is greater than corn.

Pigs Pig Feeding + Granulation or Expansion + Granulation, Both of which are more than only granulated pigs, Feed conversion rate and digestibility of energy and protein. The pigs are 8kg to 12kg, 10kg ~ 35kg and 35kg ~ 110kg weight stage, and the expansion of the pellets is superior to the feed conversion of the feed. Some people have studied the effects of powder, ordinary pellets, puffed materials, puffed particles and expansive particles, and the effects of pig production performance and nutrient digestibility. In terms of improving weight gain and feed conversion, piglets and growth pigs prefer ordinary The effect of the particles is superior to the expansion pellet material; the effect of growing the fatty pig is superior to the puffed particles; while the effect of the piglets in the ordinary particles is inferior to the puffed material or puffed particles; expansion or puffed and system When the particle processing is combined, there is no effect on the influence of the digestive rate; the expansion or expansion processing of the diet is performed, and the improvement of the production performance of the powder and the particulate material is similar to the reduction in the age of the pig. That is, with the age of pigs, granules are processed for diet, enough to achieve its production performance. The effect of expansion and puffing on the production of pigs is also related to the nature of diet. Expansion and puffed fibrous diet, improved effects on pig production properties, greater than treatment with high degree of digestible or corn – soybean diet. The effect of expansion and expansion processing on the vitamin stability in the feed is great. Growing pig feeding before adding vitamin diet, growth rate and feed conversion are lower than expanded to add vitamin groups.

In summary, the feed is properly processed, and the nutritional value of the feed can be improved varying degrees and the production performance of pigs. Potentially reduce the pollution of livestock and poultry excrement on the environment. Although hot processing has many advantages, it has increased processing cost, reducing the stability of vitamins and the activity of enzymes, and should be emphasized for the application.
