Effect of Feed Processing Process on Pig Production Performance

Pig field lengths typically have a lot of choices on feed processing, which can improve production performance and reduce production costs is most acceptable. At the same time, they refuse to use the processing methods that cannot achieve expected production performance and increase costs. During the period in which the feed cost is high, the selected feed processing method needs to be reassessive to determine whether the cost of feed costs exceeds the increase in additional processing processes, thereby reducing total production costs. The article refers to the literature related to the feed processing process, which is described in the way effectively improves economic benefits and is generally accepted by the field leader in the farm. When evaluating feed processing methods, comprehensive considerations are needed, and most important of which is the need to increase processing costs and impact on production performance.

1 Full-mixed feeding and free food feeding, pigs feeding all mixed feeds are often more faster than freely eating feed, this is mainly because all mixed feed can better control nutrient eleme. Incident. However, this advantage of full mixed feed is often offset by the cost of the feed crushing, mixing, and maintenance. In terms of feed utilization efficiency, the difference is not significant. In addition, full-mixed feeding is a higher level of mechanical automation, while freely eating feeding methods requires more stringent monitoring.

2 corn or high-grain feeding method and pulverizing feeding method freely elective food, the impact of total particulate or pulverized corn on pig production performance is different; the sorghum after the mixing of the whole grain beam is usually improved. The growth rate and feed utilization of pigs have been pointed out, but this difference is not very significant. Although there is no relevant information on the effects of total or crushing sorghum to pig production performance, the previous studies have shown that the sorghum crushing can increase the average daily mass increase by 4%, and reduce the amount of consumption of 3%. For the above differences, it is recommended to comprehensively assess the combination, maintenance and human cost increase in this processing method to determine the final economic benefits. It should be noted that all composition ingredie in all mixed feeds, including corn and sorghum, all need to be pulverized or crushed. If corn or sorghum is unclear, it is mixed with other compone, which will generate a grading phenomenon, thereby affecting the uniformity of the feed.

3 Senile Other Processing Works in Texas has conducted some rarch on the effects of sorghum processing methods on the performance of fatty pigs, some of which are shown in Table L. When the quality of the pigs increased from 32 kg to 55 kg, the protein content was 16% of diet, and then replaced with a diet of 14% of the protein content until the mass increased to 95 kg. The increase in pigs in the sorghum dry pulverization treatment group is superior to the microwave treatment group and the vapor tablet treatment group, while the flesh ratio in the vapor block treatment group is lower than the other 2 treatment groups. There is no significant difference in carcass quality.

Baking (cooked) corn rarch results show that corn baking (cooked) treatment does not affect the growth rate of pigs, but for feedThe conclusions that use efficiency effects are inconsistent. Through the summary of the above rarch materials, it can be found that baking (cooked) corn to the pig’s feed utilization efficiency seems to have some benefits, but this benefit is not enough to promote the pig farm to buy a corn baking alone (cooked) equipment. 5 Granular feed and powder particulate feed usually increase the average daily growth of growth pigs and fatty pigs by 5%, and the feed utilization increases by 10% 12%. The number of particulate feeds used by most farmers may not prove the value of a granulator. Similarly, the benefits of using particulate feed are not necessarily demonstrating the energy consumption costs to the planting process in the granulator. However, in the case of all the materials required, the particle feed is quite economically compared to the powder. 6 The effect of liquid feed for mushrooms, there is no significant difference between dry feed and liquid feed, but feeding dry feeds typically improve feed conversion rate. In addition, the two have no significant difference in living quality reduction rate, refrigeration rate and other carcass index measureme. The cost of liquid feed is higher than that of dry feed, and it is also a problem separated and feeding is also a problem. In addition, under low temperature climatic conditions, use liquid feed will also bring a lot of trouble. Liquid feed is more likely to cause equipment corrosion compared to dry feed. 7 wet material feeding method Ohio Agricultural Rarch and Development Center has been related to the method of feeding the wet material. Wet materials are usually mixed by dry feed and water in a ratio of 1: 1.3-1: 1.5. The wet material is not a liquid, but contains sufficient moisture. In addition, moisture in the wet material can also meet the needs of pigs on water. In a study, scientific rarch workers observed the effect of standard mixed protein feed through dry feed and wet material on the production of growth and fatty pig. The results show that the wet material increases the daily seasoning amount of 0.26 and 0.21 kg, respectively, and increases daily mass 0.10 and 0.08 kg, respectively. In the eight growth and fertilizer phases, the seven stages of which can be found to have a moisture to promote the weight of the pig. In addition, pigs in the form of moisture feeding have a higher water eating ratio. 8 Conclusion What kind of feed processing process is exactly depends entirely in the maximum economic benefits, this principle is also applicable to the aquacultians of pigs. Some feed processing methods can achieve higher daily mass and (or) feed utilization, but this is also economical or uneconomical, which mainly depends on the following factors, such as the cost of processing, processing. , The required equipment and the degree of automation to be achieved in the feeding system.
