Cabrera et al. (1994) reported, corn pulverized granularity pair The production performance has no effect, and the sorghum is pulverized from 1000 mu; m to 400 mu; M, the egg yield, the egg weight and the conversion rate of the feed are improved; reduce corn and sorghum particle size cannot be improved 4 ~ 14 days 7 ~ 28 days of production performance of aged meat chickens. Healy et al (1994) reported that for corn, hard embryos sorghum and soft embryo sorghum, the highest weight of the 7-day-old chicken 0 ~ 7D increased heavy weight and feed conversion rate of 700,500 and 300 mu; MU Healy et al. (1994) believes that if the sorghum is reasonably processed, the nutritional value of the meat chicken is similar to corn. Kansas State University discovered that the feed particle size was lowered from 1000 mu; m to 500 mu; M, the weighting speed of the meat chickens of complex diet was increased, and broiler on the feeding composition was smaller.

Report, weaning piglet diet is reduced by 900 mu; m to 500 mu; M The increase in cost is less than the compensation generated by the feed conversion. When the growth pig diet is 509 ~ 1026 mu; m changes, there is no significant effect on the daily gain of pigs, but with the decrease in particle size, the feed conversion increases the best particle size of the production performance. 509 ~ 645 mu; m (Zanotto et al, 1996). When the fertilizer pig diet, the corn pulverized particle size is from 400 to 1200 mu; M, the particle size is reduced by 100 Mu; M, the feed conversion increases by 1.3% (Wondra et al, 1995a). 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% (Wondra et al, 1995C, D), respectively. Kim (1995) also found that the composition of the corn granularity from 1000 Mu; M fell to 500 mu; M little. Suitable particle size of 0 to 14 days of 0.35D and 14 to 35D feed pigs is 300 mu; M and 500 MU; M (HealTy et al, 1994); growth and fatty pig and sows are 500 ~ 600 mu; M and 400 ~ 600 mu; m ( Wondra et al, 1995c, d).

2 Dietary mixing uniformity H4J China feed industry information network – based on feed, service animal husbandry
McCoy et al. (1994) reported when feeding the meat chicken At the time of the price of food, the mixed uniformity of the diet has little effect on its growth performance, and the feed conversion rate increases with the mixing uniformity. It is linearly improved; while feeding 80% NRC standard for meat chicken is not full price diet. The growth performance increases with the mixing uniformity of the diet (the variation coefficient is reduced from 40.5% to 12.1%), which is reported. TRAYLOR, etc. (1994), when the coefficient of mixed uniformity of the piglet diet is reduced from 106.5% to 12.3%, The daily gain and feed conversion increased by 32.5% and 19.2%, respectively; while the mixed uniformity of the fatty pig diet was reduced from 53.8% to 14.8%, the production performance was not significantly improved. Therefore, the diet mixed uniformity The effect of animals and food-free diet is large. Therefore, the appropriate variation coefficient of mixed uniformity of the meat chickens and piglets is 12%; the mixed uniformity of fat feed pigment is 15%.

3.1 Because the particles have many advantages from the powder, it is widely used in the production of cocks and turkey and weaning piglets.Heavy and feed conversion is better than powder. Recently, the impact of granulation quality and granulation and fine powder in the diet is concerned about the performance of meat chickens. Wilson et al. (1998c) reported that 3 to 6 weeks old broilers were feeding full pellets, the production performance was higher than those of the food granules + fine powder diet. The sensitivity of the fine powder content of the turkey and the particulate material is higher than the meat chicken. Proudfoot and Hulan (1982) found that the powder content in the turkey particles increased from 0 to 60%, and its production performance decreased.

For the soybean powder, it is reduced from 27.36 to 14.30 mg / g. . John- Ston et al (1998a, b) gives fertilizer pigs and sow, feeding corn or sorghum powder. There is no significant difference. TRAYLOR et al. (1996) reported that the pigment of pigs and feed conversion and feed conversion were increased in 5 days ago, and the powder is increased by 25% and 36%, and the particle diameter (2 ~ 12mm) does not affect the growth of pigs. Performance; pig daily weight and feed conversion rate and feed rate of 4 mm in the production of particles during the age of 0 ~ 29; the growth rate of the pigs in 29 days-aged ~ fertilizer, not affected by the feed form, but the feed of pellets The conversion rate is superior to the powder. Stark et al (1994) also reported that when the piglet is sieved, the feed conversion is increased by 15% or 30% of the particles of 15% or 30% fine powder; fatty pigs are prepared in the food, and the pellets The proportion of fine powder is increased from 0 to 60%, and the feed conversion decreases, and there is no significant difference in the digestibility of daily gain and nitrogen and its thickness.

Zanella et al. (1998) reported that puffed all fat soybeans were added to the meat chicken diet, but can be more soybean meal or Baking all fat soybeans increase the weight gain and feed conversion of the meat chicken. GARCIA, etc. 91998) expands the barley, significantly increase the weight gain of the 14-day-aging meat chicken; and the abundance of barley expansion can significantly improve the weight of the meat chicken. Wilson et al (1998a) reported that the meat chicken weighting and feed conversion conditions were the best corn expansion processing conditions, and the temperature of the temperature was 71 ¡ã C, which was 12 kWh / t; and the sorghum corresponding value was 79 ¡ã C and 9 kWh / t. When making a meat chicken pellet, the normal conditioning is changed to an expander tension, and the metabolic energy content and the digestibility of fat and starch are improved (Peisker, 1993), and the feed conversion rate is improved (Wilson et al., 1998B) . Rollins (1996) reported that the steam energy tuning, enhanced steam regulation and expander regulation, increased the weight gain of meat chickens by 1%, 1% and 5%, and the feed conversion rate is improved by 4%. 3% and 3%.

[1996) reports that the whole grease soybean is injected into the urging expansion, does not affect the lysine content, obvious Reduced trypsin inhibitory factor content and protein discrete index. CAO et al. (1998B) When the cone pressure is increased from 0 to 56kg / cm2, the daily gain of weaning piglets is increased in curve with feed intake. Richarclson et al. (1998) found that puffed soybeans have no significant improvement in their dry matter digestibility, while puffed cottonseeds can improve their dry matter digestibility. O RSQUO; Doherty and Callan (1998) with raw peas production performanceSimilar to the foundation diet. TRAYLOR (1997) In the fertilizer pig diet based on corn, sorghum or wheat powder, the digestibility of nutrients can be improved due to expansion processing, but in the wheat-based diet, nutrient digestibility Do not improve due to expansion; the feeding crude fiber content is higher than corn, the sorghum is lower than corn, and the degree of nutritional value after expansion is greater than corn. Medel et al (1998) also found that corn in the early weaned piglet pig diet, improved its production performance and less than barley. PIAO et al. (1997)

Saurer et al. (1996) reported that the piglet diet puffed + granulation or expansion + granulation, both only granulated Increasing the increase of pigs by 8%, feed conversion rate of 6% and energy and protein of 3% and 6%. The pigs were in the 8 ~ 12, 10-35 and 35 ~ 110kg weight stages, and the expansion pellets were extracted, and the feed conversion was superior to the precipitation of ordinary mass-striped particles (Teisker, 1995). CHAE and HAN (1998) have studied the effects of powder, ordinary pellets, puffed materials, puffed particles and expansive particles, and the effects of pig production properties and nutrient digestion rates, in terms of improving weight gain and feed conversion rate, piglets The effect is better than the expansion pellet material with the growth pig, and the effect of growing the fatty pig is superior to the puffed particles; while the effect of the piglets eat ordinary particles is inferior to the pellet or puffed particles. Durable or expansion processing, which can improve the tendency of energy dissipation rates from powder, but no effect on protein digestibility; when expansion or puffed is combined with granulation, there is no effect on the influence of digestibility; The diet is expanded or expanded, and the improvement effect of powder and particulate material on pig production performance seems to increase with the reduction in pig age. 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. When expansion and puffed fibrous diet (Sauer et al, 1996), the improvement of pig production properties is greater than the treatment of highly digestible or corn – soybean diet (CHAE et al, 1997a).

Sommer et al. (1994) reported that the crude protein solubility angle from 120, 130 and 150 ¡ã C expanded vegetarian seeds. 40% of the raw to 17%, 15% and 13%, the corresponding rumen degradation rate dropped from 65% to 44%, 35% and 38%, respectively; the rapeseed meal in the stomach non-degradation protein residue in small intestines Increased. Expansion can increase the fluoroman protein content of the cereal with soybeans by 4 times, so that soybean meal, vegetablesThe increase in the increase in the increase in the increase in the protein content of corn flour powder (Elstner, 1996). GOELEMA and VAN DER POEL (1996) expanded under 120 ~ 150 ¡ã C, which reduces the degradation rate of proteins in most feed raw materials and protein mixes, but the digestibility of proteins in the unexplained residue is not affected. And even improved. When the bulls fed 5 to 20 weeks of milk, the standard milk production was added to 6.4% (Peisker, 1995).

3.3 Dry Rolling, Steam Rolling and Steam Table Dry Rolling, Steam Rolling and Steam Table Wide wide application in dairy production. DAUN et al. (1998) feeding the corn for dairy or steam tablets, and the result of the production performance after the milk has no significant difference, while the maize that fed the vapor tablets after childbirth, it is more feeding and pulverized Corn, there is a tendency to increase milk production. ARIZONA’s research shows that the corn or sorghum of the vapor tablet can be laminated by dry rolling and steam rolling of milk cows, 8% of milk protein production and raising economic benefits 0.48 US dollars / D, where sorghum The improvement effect is greater than corn (Santos et al, 1997). When feeding the sorghum or corn for dairy cattle, the two production properties are similar (Santos et al, 1997). When the cow is 0.30kg / l, the milk is 0.30kg / L, the milk volume is more than 0.25 kg / L of the tissue, and the steam roller corn or coarse pulverized corn is increased by 8% (YU et al, 1995). Corn (YU et al, 1995) and sorghum (Santos et al, 1994a, b) were 0.26 to 0.32 and 0.30 to 0.36 kg / L, respectively, respectively. CROCKER et al. (1998) feeding dairy cattle, feeding different proportional tablets, corn and dry crushing corn, and increased ratio, increased digestibility of starch, C18: 2 fatty acid proportion in cream increased.

In summary, the feed is properly processed, and the nutritional value of the feed can be improved varying degrees to reduce the production performance of livestock and poultry, potentially reduce the environmental pollution of livestock and poultry. 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. In the future, in addition to further study the mixing uniformity of the diet, the mass preventive method before granulation (ordinary steam or expander regulation) and the quality of the particulate material on the nutritional value of the feed nutrition and the production of livestock and poultry are also needed to be in addition to corn. Outside the sorghum, other grain and protein feed is suitable for pulverizing particle size, and accurate and simple and practical measurement of the mixed uniformity of the diet, affecting the factors of the granulation and its control method, the inflation and the infrastructure of different raw materials and diet and the diet. Its application of appropriate conditions such as the application of unconventional feed resources (such as feather keratin), suitable conditions such as microwave processing feed.
