How to determine the newness of suckling pig corn

First, learn from the experience of new corn seeds: w3m China feed industry information network - based on feed, service animal husbandry

(1) The morphological difference is mainly the seed luster. Compared with the new seeds (the same variety), the seeds are stored and dried for a long time, and the seeds themselves consume nutrients, which are often darker in color and harder in the embryos. The keratin is less in the embryos and the powder is more. Chen is easy to be wormed by rice, and often has fine round holes in the embryo. When you put your hand into the seed bag and pull it out, there is powder on your hand. W3m China Feed Industry Information Network - based on feed, serving animal husbandry

(2) Physiological differences Chen's seeds have weak viability, and the germination rate and germination potential are lower than the new seeds. The ability of arching soil in the field is poor. This is also the “buddy and no potential” that often occurs in production. The seeds have sprouted but are distorted in the soil and cannot reveal the reason for the formation of seedlings on the ground.

(3) There are many self-test chemical methods for seed viability, but farmers can do red ink staining. The red ink was formulated into a solution at a ratio of 1:60, and the seeds were immersed for 15 minutes and then taken out for observation. The embryos were not dyed red or stained lightly for viable seeds. W3m China Feed Industry Information Network - based on feed, serving animal husbandry

Second, the identification measures: Brazil, Argentina is a corn exporting country, in the corn exported to it is inevitably mixed with Chen corn, so the company's acceptance is based on the overall gloss of the corn and germ color, hardness, bulk density, smashed hot corn smell and head cooking Tasting (the smell of the head, the color of the head, the external shape, the internal traits, the taste) is comprehensively evaluated for the corn used for suckling pigs.

Third, the specific requirements for acceptance: the color of the corn is bright yellow or yellowish red, the particles are full, mainly silty corn; the appearance of the germ is full, the color is bright, the handcuffs are elastic; the bulk density requires 740g/L or more; The corn is normal and fragrant, and it must not have spicy taste and taste. According to GB/T-20570-2006 corn storage quality judgment rules, it is better to have a comprehensive score of 80 or more.

Use specific requirements: review the milk pig corn before use, the sensory quality can only be used, the hot corn smell will be judged at the first time after crushing, if there is any doubt, immediately sampled into the laboratory for the head cooking evaluation, the score Less than 70 points is strictly prohibited for use in suckling pigs. (Crushing corn is required to be used up on the same day. After the company detects the crushed corn, it will drop about 10 points after storage in the warehouse for 1 day. The main reason is that the smell of corn changes greatly, and it cannot be used after 4 days. In the production of pigs, the impact on palatability is relatively large).

Fourth, corn nest cooking evaluation operation (company suckling pig corn does not exceed 1 month) w3m China feed industry information network - based on feed, service animal husbandry

For the first time: When the corn arrives at the company, choose the corn with good appearance color for the cooking of the head, and evaluate the corn with the taste of more than 80 points. W3m China Feed Industry Information Network - based on feed, serving animal husbandry

The second time: Before use, the weekly special milk for stocked suckling pigs was evaluated for the first time, and the corn with more than 80 points was used for the production of suckling pigs. W3m China Feed Industry Information Network - based on feed, serving animal husbandry

The third time: after smashing, the corn is sampled and tested for the cooking of the head, and the corn with a taste of more than 70 is used for the production of suckling pigs (the effect of cross-contamination of the process on the evaluation of corn worms). It is strictly forbidden to use the pigs for more than 2 days after crushing. It is best to use it on duty when it is on duty.
