1.顆粒料的質(zhì)量
總體上質(zhì)量穩(wěn)定 ； 抗拉稀效果好；所反映的問題(硬度,適口性 都是些老問題.2005年,豬料的配方和所使用原料都比較穩(wěn)定;加工工藝變化不大;但有些飼料廠的質(zhì)量在提高.市場人員一直都在反應(yīng)顆粒料的適口性問題;顆粒料占豬料的比重也在不斷減少；業(yè)務(wù)員對顆粒料的信心不足.提高業(yè)務(wù)員的信心;改善顆粒料的適口性;提高顆粒料的質(zhì)量。
2.玉米質(zhì)量
2005年使用的玉米為二級;提高玉米的質(zhì)量必須改變采購方式.玉米在顆粒料中比例最大;玉米中含黃曲霉素,玉米赤霉烯酮等毒素;玉米的霉變,雜質(zhì)等影響飼料適口性.很多公司使用的玉米,為"糧莊"玉米,是玉米收購點(diǎn)自己收購的玉米,讓他們把好關(guān)確實(shí)很難�，F(xiàn)在，大部分飼料廠直接從農(nóng)戶收購玉米，自己把關(guān)，質(zhì)優(yōu)價(jià)廉自己到農(nóng)戶,市場上收購;或培養(yǎng)小玉米供貨商,從農(nóng)戶收購玉米后,直接送到公司。提高玉米的驗(yàn)收標(biāo)準(zhǔn),幫助解決發(fā)票的問題。
3.原料粉碎粒度
影響顆粒飼料質(zhì)量的因素有：飼料配方（40％），粉碎（20％），調(diào)質(zhì)（20％），壓模選用（15％），冷卻和干燥（5％）.玉米細(xì)粉碎后，其效果跟膨化玉米差不多。經(jīng)粉碎的產(chǎn)品越細(xì)致均一，則調(diào)制的效果越好.雖然膨化玉米，膨化大豆 粉質(zhì)量好，卻沒有驗(yàn)收標(biāo)準(zhǔn)和好的生產(chǎn)廠家。有部分飼料廠對乳豬飼料進(jìn)行細(xì)粉碎，效果不錯。魚料的二次粉碎技術(shù)已經(jīng)成熟.建議乳豬顆粒料中的玉米，豆粕 ，大米蛋白粉等進(jìn)行二次細(xì)粉碎。設(shè)備改造需要1萬元，有可操作性。
4.顆粒的硬度
顆粒硬度大,影響適口性。小豬跟小孩差不多,喜歡脆,軟的食品。但硬度太低，含粉率會提高 次粉中含有α-淀粉,小麥面筋粉,是天然粘合劑,減少用量可以減少顆粒硬度.脂肪粉提高用量,能降低顆粒硬度.顆粒硬度可以用顆粒料硬度儀測量,粗略的測試可以將飼料泡在水中,以多長時(shí)間散開估計(jì)硬度.現(xiàn)在是15分鐘,以8-10分鐘全部散開為硬度比較合適.以前曾做過試驗(yàn),固體磷脂（含50％磷脂）多加0.5%可以很好的降低顆粒硬度,可脂肪粉中含8%的磷脂,具體效果不明確.逐漸降低次粉的用量,增加脂肪粉的用量,來調(diào)節(jié)乳豬料的硬度。
The English version
1. The quality of the granular material
Overall quality is stable; Anti diarrhea effect is good; The problems reflected by (hardness, palatability is all some old problems. In 2005, the pig feed formula and used raw materials are stable; processing technology changed little; but some in improving the quality of feed mills. Marketers have been response granular feed palatability problems; grain accounts for the proportion of pig feed has been reduced, the salesman for lack of confidence. The granular material to improve the confidence of the salesman; improve the palatability of granular materials; improve the quality of grain.
2. The quality of corn
Use of corn for the secondary in 2005; Improve the quality of the corn must change the way of purchasing. Corn in granular material proportion is the largest; Containing aflatoxin in corn, corn gibberellic ketene and other toxins; Corn mildew, impurities such as impact feed palatability. Many companies use of corn, for "food" zhuang corn, corn is collection spot their acquisition of corn, let them turn really hard to the good. Now, most of the feed mills directly from farmers to buy corn, their control, high quality and low price to the farmers, buy on the market; Suppliers or develop small corn, from farmers to buy corn, directly to the company. Improve the corn acceptance criteria, to help solve the problem of invoice.
3. Raw material crushing granularity
Factors affecting the quality of pellet feed is: feed formula (40%), crushing (20%), quenched and tempered (20%), die (15%), cooling and drying (5%). The corn after fine grinding, the effect with puffed corn. Through crushing products more meticulous and uniform, the modulation of the better the results. Although puffed corn, puffing of soybean powder are of good quality, but there was no acceptance standard and good manufacturers. Some feed mills to fine crushing of Suckling pig feed, effect is good. Fish is the secondary crushing technology is ripe. Suggest Suckling pig grain of corn, soybean meal, rice protein powder, etc for secondary crushing. Equipment modification need 10000 yuan, has maneuverability.
4. The hardness of particles
Grain hardness, the impact of palatability. Pig just like children, like crisp, soft food. But low hardness, powder content can improve powder contains alpha starch, wheat gluten powder is a natural adhesives, reduce dosage can reduce the grain hardness. Fat powder increase dosage, can reduce the grain hardness. Particles can be measured with grain hardness tester, hardness test can be roughly feed bubble in the water, how long it will take to scatter estimates hardness. Now it is 15 minutes, all spread out 8 to 10 minutes as hardness is more appropriate. Previously worked as a test, solid phospholipids (containing 50% lecithin), add 50% can reduce the grain hardness, good fat powder contains 8% of phospholipids, specific effect is not clear. Gradually reduce The Times of the amount of powder, increase the amount of fat powder, to adjust the hardness of the Suckling pig feed.
