Problems solved by technology

However, because these farmers still use standard compound feed or grain feeding during the extended fattening period, not only the cost per unit of weight gain has increased significantly, but also the backfat of the slaughtered pigs is too thick and the carcass quality is reduced
[0004] There are also some farmers who have noticed the good effect of forage and green feed on improving the quality of pork. They feed a certain amount of forage during the growth and finishing stage of pigs. Although this method improves the quality of pork, it delays the growth of pigs. , the daily weight gain and feed-to-meat ratio are unsatisfactory, and if the pork is still slaughtered at the normal slaughter age, the flavor and taste of pork will be very limited.

Embodiment 1

[0012] Example 1: Firstly, the Du-chang-big pigs were raised to 170 days old with the feed that met the feeding standards, and then fed with 18% oat grass dry powder, the digestible energy of dry matter was 15.20MJ / kg, and the rest of the nutritional indicators met the feeding standards The extended fattening period diet was used, and the fattening continued for 45 days before slaughter. The dry oat grass powder used is the dry grass powder processed from the oat grass harvested at the early stage of Lashu in the market. The extended fattening period diet was prepared and processed into pellets at one time according to the proposed feed formula before feeding.

Embodiment 2

[0013] Example 2: First, the Large White-Taihu pigs were raised to 180 days old with feed that met the feeding standards, and then fed with 20% ryegrass in the dry matter, the digestible energy of dry matter was 15.10MJ / kg, and the rest of the nutritional indicators met the feeding standards The extended fattening period diet was used, and the fattening continued for 55 days before slaughter. The ryegrass used is enzyme-added silage powder prepared from fresh grass harvested at the heading stage. The extended fattening period ration was mixed according to the proposed feed formula before feeding to make feed for five days. The feed type was wet powder, and it was vacuum-packed in plastic bags for later use.

Abstract

The invention discloses a feeding method for improving the quality of pork. The method comprises the steps of firstly, feeding pigs with fodder which meets the feeding standard until the pigs reach the usual slaughtering days of age, namely 165-180 days; then entering an extensive fattening period, wherein in the period, fodder which contains 10-50% of forage grass, has dry-substance digestible energy which is lowered by 1-20% than the feeding standard, and has other nutritive indexes in accordance with the feeding standard is adopted for 30-150 days of extensive feeding. In this way, the effects of increasing sedimentation of flavor substances of the pork and improving the flavor, color, luster, tenderness, mouthfeel, water-holding capacity, oxidation resistance and other properties of the pork and the carcass quality of pigs on the premise that the period before slaughtering is properly prolonged and the fat condition is properly controlled. The feeding method is suitable for all pigvarieties.

Description

technical field [0001] The present invention relates to a raising method for improving the quality of pork. Specifically, the pigs are raised to the usual slaughtering age with feed that meets the feeding standards, that is, 165-180 days, and then enter the extended fattening stage. In this stage, pigs are fed with 10~50% forage grass, the digestibility of dry matter is 1%~20% lower than the feeding standard, and other nutritional indicators meet the feeding standard for extended feeding for 30~150 days, so as to achieve the goal of appropriately extending the slaughter period and properly controlling the body condition. Under the premise of increasing the deposition of pork flavor substances, the results of improving the quality of pork and pig carcass. Background technique [0002] The current widely used pig raising technology is to use full-price feed that meets the feeding standards for breeding. Under this technology, pigs grow very fast, and generally reach the slaugh...
