1.颗粒料的质量
总体上质量稳定 ; 抗拉稀效果好;所反映的问题(硬度,适口性 都是些老问题.2005年,猪料的配方和所使用原料都比较稳定;加工工艺变化不大;但有些饲料厂的质量在提高.市场人员一直都在反应颗粒料的适口性问题;颗粒料占猪料的比重也在不断减少;业务员对颗粒料的信心不足.提高业务员的信心;改善颗粒料的适口性;提高颗粒料的质量。
2.玉米质量
2005年使用的玉米为二级;提高玉米的质量必须改变采购方式.玉米在颗粒料中比例最大;玉米中含黄曲霉素,玉米赤霉烯酮等毒素;玉米的霉变,杂质等影响饲料适口性.很多公司使用的玉米,为"粮庄"玉米,是玉米收购点自己收购的玉米,让他们把好关确实很难。现在,大部分饲料厂直接从农户收购玉米,自己把关,质优价廉自己到农户,市场上收购;或培养小玉米供货商,从农户收购玉米后,直接送到公司。提高玉米的验收标准,帮助解决发票的问题。
3.原料粉碎粒度
影响颗粒饲料质量的因素有:饲料配方(40%),粉碎(20%),调质(20%),压模选用(15%),冷却和干燥(5%).玉米细粉碎后,其效果跟膨化玉米差不多。经粉碎的产品越细致均一,则调制的效果越好.虽然膨化玉米,膨化大豆 粉质量好,却没有验收标准和好的生产厂家。有部分饲料厂对乳猪饲料进行细粉碎,效果不错。鱼料的二次粉碎技术已经成熟.建议乳猪颗粒料中的玉米,豆粕 ,大米蛋白粉等进行二次细粉碎。设备改造需要1万元,有可操作性。
4.颗粒的硬度
颗粒硬度大,影响适口性。小猪跟小孩差不多,喜欢脆,软的食品。但硬度太低,含粉率会提高 次粉中含有α-淀粉,小麦面筋粉,是天然粘合剂,减少用量可以减少颗粒硬度.脂肪粉提高用量,能降低颗粒硬度.颗粒硬度可以用颗粒料硬度仪测量,粗略的测试可以将饲料泡在水中,以多长时间散开估计硬度.现在是15分钟,以8-10分钟全部散开为硬度比较合适.以前曾做过试验,固体磷脂(含50%磷脂)多加0.5%可以很好的降低颗粒硬度,可脂肪粉中含8%的磷脂,具体效果不明确.逐渐降低次粉的用量,增加脂肪粉的用量,来调节乳猪料的硬度。
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.
