5 results about "Alfalfa hay" patented technology

The invention belongs to the field of animal feed, and particularly relates to a feed composition for improving body functions of camels and nutritional effects of camel milk and application of the feed composition. The feed composition takes first-crop alfalfa hay as a basic raw material, contains corn flour, soybean meal, flax residues, oil sunflower residue powder, rose willow powder, sea-buckthorn powder, elaeagnus angustifolia powder, alhagi sparsifolia powder or peganum harmala powder, soybean grass powder and cistanche deserticola residue powder, and is further matched with a Chinese wolfberry extract and a ginkgo leaf extract to serve as a functional additive. The feed is suitable for the camels in the lactation period, can improve the immunity and oxidation state of the camels, and improves the content of immunoglobulin, amino acid, folic acid, taurine, unsaturated fatty acid and other components in the milk of the camels. The obtained camel milk is suitable for producing dairy products with nutrient enrichment value. The feed is natural in component source and good in palatability, and can be widely applied to the field of camel breeding.

The application focuses on the field of agricultural informatization and remote sensing application technology, and particularly relates to a kind of alfalfa yield estimation method based on multispectral and physical constraint sample enhancement. The method first acquires unmanned aerial vehicle multispectral image data corresponding to the alfalfa growth period, and lays out field quadrats with equal area in the image coverage area, collects measured data of alfalfa hay yield, leaf area index, chlorophyll content and leaf equivalent water thickness, and constructs an initial sample set. Then, input each parameter data within a reasonable range, generate predicted multispectral samples that meet the physical consistency constraint using the radiation transfer model, to expand the sample space. The measured samples and predicted samples are fused to construct an alfalfa hay yield estimation training data set. Based on the training data set, a mapping model between unmanned aerial vehicle multispectral features and alfalfa hay yield is established, and the alfalfa hay yield is estimated through machine learning.

This utility model relates to the field of agricultural machinery and equipment. Specifically, it is an alfalfa harvesting and hay-raking device, including a protective shell with wheels rotatably connected to the bottom of the shell, and a swing arm rotatably connected to both sides of the protective shell. A material-feeding component is fixedly connected to the side of the swing arm away from the protective shell. The device uses a corrugated sleeve to prevent dust and other impurities from adhering to the screw surface during operation, which could cause the adjusting block to jam. By setting the material-feeding component, when the protrusion rotates to the inner side of the device with the hay-raking disc, the limiting wheel contacts the protrusion. At this time, the limiting wheel will press down on the protrusion, causing the compression spring to be compressed. After being compressed, the protrusion drives the guide rod, the fixing frame, and the top block to move downwards synchronously. When the top block moves downwards, it can push the alfalfa hay stuck between the spring teeth downwards, effectively preventing the alfalfa hay from accumulating and jamming between the spring teeth, and ensuring the smooth operation of hay-raking.

The invention discloses an amaranthus hypochondriacus silage total mixed ration formula and a feeding method, and relates to the technical field of silage. Comprising the following raw materials: modified amaranthus hypochondriacus silage stalks, amaranthus hypochondriacus silage leaves, corn silage, alfalfa hay, corn, modified cottonseed meal, soybean meal, wheat bran, a buffering agent, a functional agent, modified attapulgite, a cattle fattening premix, stone powder and table salt. According to the beef cattle feed disclosed by the invention, the added modified grain amaranth silage stalks can reduce the digestion barrier of beef cattle to coarse feed, guarantee the utilization efficiency of daily ration fibers, and avoid the influence on the feed intake and the weight gain effect of the beef cattle due to too high proportion of low-digestion fibers; the added modified cottonseed meal provides crude protein with high utilization rate for beef cattle, and ensures the protein deposition and growth performance of the beef cattle in the fattening period; the added functional agent can inhibit the reproduction of harmful flora, improve the digestion and utilization rate of the whole feed, and guarantee the stability and high efficiency of rumen fermentation.

The invention provides a feed for improving production performance of dairy cows and a preparation method of the feed. The feed comprises the following components in percentage by mass: 17.35% of alfalfa hay, 1.29-7.09% of beet grain meal, 19.84-23.44% of corn, 3.6-5.8% of whole cotton seeds, 0.82% of sodium bicarbonate, 29.57% of silage and the balance of 21.73% of concentrate supplement, and the silage comprises corn silage and tomato seedling silage. The preparation method of the feed is rapid and convenient, and the prepared feed can improve the milk fat correction milk yield, milk yield, feed conversion rate and milk protein rate of dairy cows, has positive influence on the protein metabolism capability, has no damage to the liver and kidney of an organism, and can improve anti-inflammatory factors and milk quality.
