6 results about "Abomasum" patented technology

Disclosed are uses of at least one alpha-1,4 / 1,6-glycoside hydrolase (GLCH) as a feed additive for a ruminant wherein said hydrolase: (a) has at least 20% activity at pH less than or equal to 3 in the presence of pepsin as compared to activity of the hydrolase at pH 6 in the presence of pepsin, (b) said hydrolase is active in at least two of three digestive chambers of a ruminant comprising a rumen, an abomasum and a small intestine and (c) the hydrolase works with pancreatic amylase to increase glucose yield.

The invention relates to the technical field of dairy product processing, in particular to a fried cheese formula and a preparation method thereof, and the fried cheese formula comprises the following components by mass: raw milk subjected to standardization treatment, animal type chymosin, a leavening agent, calcium chloride and edible salt; the animal type chymosin is a mixture of rennase and bovine pepsase according to a mass ratio of 70: 30, the activity of the chymosin is greater than or equal to 890 IMCU / g, the addition amount of the chymosin is 43 g / t, and the chymosin is used for improving the curding efficiency and the structural stability; the leavening agent is lactococcus lactis subsp.cremoris and lactococcus cremoris, the addition amount of the leavening agent is 4D / t, and the leavening agent is used for increasing the flavor and fragrance of the product; the addition amount of the calcium chloride is 70g / t, and the calcium chloride is used for strengthening protein network crosslinking. According to the invention, the raw milk is standardized, so that the quality stability of the product is obviously improved; the thermal stability is optimized, and the eating scene is expanded; and strains capable of generating flavor substances are added, so that flavor levels are rich, the mouth feel is fine and elastic, and the eating experience is upgraded.

The invention relates to the technical field of feed additives, in particular to a sustained-release feed additive containing eucalyptus globulus essential oil for rumens of cattle and sheep. The CO2-triggered eucalyptus globulus essential oil sustained-release capsule comprises a CO2-triggered eucalyptus globulus essential oil microcapsule unit, a cobalt acetate sustained-release microsphere unit and a carrier unit. Wherein the microcapsule unit is of a three-layer core-shell structure and can respond to CO2 partial pressure in the rumen gas production peak period to achieve pulse type rapid release of eucalyptus globulus essential oil, and methanogens are accurately inhibited; the sustained-release microsphere unit adopts functionalized polysaccharide composite microspheres to load cobalt acetate, can stably release cobalt element in rumen, and slowly and continuously releases cobalt element in abomasum and intestinal tract after passing the rumen. The two parts are compounded in a physical mode and do not interfere with each other, and space-time precise delivery and function coordination at different parts of the digestive tract are achieved. The method can effectively improve the methane emission reduction efficiency, improve rumen fermentation and improve the nutrient digestibility of the feed.

The invention provides a beef cattle feed additive and a preparation method thereof, and belongs to the technical field of feed additives.Eucommia ulmoides fermentation extract is added to the feed additive, contains a large amount of chlorogenic acid and has a synergistic effect with citrus flavone, the content of fat in beef muscles is remarkably increased, nano-coated slow-release selenium yeast is added, the selenium bioavailability is increased, and the feed additive has the advantages of being capable of improving the beef quality and the like. Meanwhile, the citrus flavonoid microcapsules are added, so that the release of the citrus flavonoid microcapsules in rumen is reduced, the citrus flavonoid microcapsules are released in a targeted manner in the abomasum, and the utilization rate of citrus flavonoid is increased. The probiotics and the traditional Chinese medicine mixture are combined to inhibit escherichia coli and salmonella, and the illness probability of beef cattle is reduced. In the raw materials, through the synergistic effect of the composite mineral substances and the traditional Chinese medicine components, the anti-stress capability of the beef cattle is improved.

The utility model relates to the technical field of demonstration tools, in particular to a ruminant digestion demonstration device which comprises a yak demonstration board, a demonstration groove is formed in the front end of the yak demonstration board, a stomach demonstration table is arranged in the demonstration groove, an esophagus groove and an intestinal groove are formed in the demonstration groove, and a rumen groove, a mesh stomach groove, a valve stomach groove and a wrinkled stomach groove are formed in the stomach demonstration table. Lamp strips are arranged on the side walls of the esophagus groove, the rumen groove, the reticulum groove, the petal stomach groove, the wrinkled stomach groove and the intestinal groove; a guide groove is formed in the rear end of the yak demonstration board, a magnetic attraction block is arranged in the guide groove, a first food demonstration block and a second food demonstration block are arranged in the demonstration groove, and magnets are arranged on the first food demonstration block and the second food demonstration block; the digestion process of the ruminant animal is more vividly demonstrated through the movement of the food demonstration block I and the food demonstration block II in different grooves; and the switch of the lamp strip in each groove is controlled during demonstration, so that the demonstration steps are more highlighted, the attention of audiences is attracted, and the demonstration effect is improved.
