The present application belongs to the technical field of animal health care, and particularly relates to a fermented decoction for improving growth and immune function of broilers and a preparation method thereof. The fermented decoction for improving growth and immune function of broilers is prepared from the following raw materials by fermentation according to weight parts: radix codonopsis 8-12 parts, angelica sinensis 3-7 parts, cornus officinalis 8-12 parts, cinnamomum cassia 3-7 parts and portulaca oleracea 3-7 parts. The fermented decoction significantly increases the body weight of broilers, significantly improves the thymus index and spleen index, and increases the IgG and IgM contents in serum, thereby promoting the growth of broilers and improving the immune function of broilers. The preparation method of the fermented decoction is simple, and is suitable for industrialized production and market promotion and application.

The invention discloses a deep processing method of wheat protein and application of the wheat protein in feed, and belongs to the technical field of deep processing of wheat protein and feed additive.The deep processing method comprises the steps that disulfide bonds are broken through sulfite under the alkalescent condition, so that the protein structure is loosened, then reducing sugar is added, the pH value is adjusted back to be nearly neutral, and the wheat protein is obtained through two-stage temperature-control and humidity-control dry heat treatment; maillard grafting modification and flavor generation are synchronously realized. The whole process does not need an enzyme preparation and is simple in process route; the water-soluble protein content of the obtained product is remarkably improved, the product can equivalently replace fish meal in a broiler chicken test, and the daily gain and the protein digestibility are remarkably improved; the process is simple to operate, low in cost and easy to industrially popularize, and a brand new path is provided for high-value utilization of the wheat protein.

The broiler chicken brooding automatic constant temperature device comprises a box body, the top of the box body is open, a top cover is rotatably connected to the top of the box body through a hinge, a partition plate is horizontally and fixedly connected to the bottom end in the box body, and a plurality of hollow grooves are formed in the partition plate at equal intervals; a metal supporting net is fixedly attached to the upper surface of the partition plate, a transverse rod is horizontally and fixedly connected to the middle of the top end of the box body, and a temperature control lamp is fixedly installed in the middle of the transverse rod. According to the chicken manure cleaning device, the box body, the partition plate, the metal supporting net, the top cover, the temperature control lamp, the temperature controller, the brush, the driving assembly and the collecting box are arranged, when chicken manure on the surface of the metal supporting net needs to be cleaned, chickens do not need to be grabbed out of the box body, and a hand wheel of the driving assembly is rotated outside the box body to drive the brush to reciprocate on the surface of the metal supporting net; and the chicken manure on the metal supporting net is brushed off, so that the chicken manure falls into the collecting box, and the device is more convenient to clean the chicken manure.

The utility model relates to a welfare cage chick house which is characterized in that the welfare cage chick house is formed by stacking a plurality of layers of chicken houses, each layer of chicken house is internally provided with an annular trough, an independent waterline and a bottom net movable platform, and the welfare cage chick house is characterized in that a detachable middle partition net is arranged in each layer of chicken house to divide the chicken house into a left side and a right side; one or more detachable column separation nets are arranged in the left side to divide the left side into a plurality of independent spaces, and a detachable side separation net is arranged on the edge of the left side to enable the left side to form a closed space; or / and one or more detachable column separation nets are arranged in the right side to divide the right side into a plurality of independent spaces, and a detachable side face separation net is arranged on the edge of the right side to enable the right side to form a closed space. According to the utility model, different separation nets are opened to realize a staged space adjusting mechanism (the separation nets are gradually opened in four stages), and the whole-cycle requirements of chicks from incubation to maturity are met from a closed cage to an open space.

The invention discloses a molecular biological identification method and application of fast large and small white feather broiler chickens, a molecular marker is obtained by amplifying genome DNA of a chicken to be detected by adopting sequences shown as SEQ ID NO.1 and SEQ ID NO.2, allele is detected by capillary electrophoresis, and the chicken containing 309 or 311 bp allele is the small white feather broiler chicken; the chicks which do not contain 309 and 311 bp alleles are fast and large white feather broiler chicks; the method utilizes allele difference to identify the fast large and small white feather broiler chickens, and has the advantage that the fast large and small white feather broiler chickens can be identified quickly and accurately. Moreover, the method is simple to operate, easy to operate in a laboratory, convenient to popularize and use in a basic level and wide in market application prospect, and in addition, the detection kit developed based on the method can generate considerable economic benefits and good social value.

The invention discloses a method for predicting wheat standard ileum amino acid digestibility of laying hens in a brooding period. The method comprises the following steps: determining physical characteristics, chemical components and amino acid contents of wheat samples from ten different sources; preparing a test feed, and carrying out a feeding test on Jingjing No.8 laying hens in a brooding period (28-31 days old); determining the standard ileum amino acid digestibility of the 31-day-old laying hens to the wheat of each source; and based on the data correlation, establishing a prediction equation of the wheat standard ileum amino acid digestibility of the laying hens in the brooding period by adopting a stepwise regression method. The constructed prediction equation can accurately predict the standard ileum amino acid digestibility of the laying hens in the brooding period to the wheat, an effective tool is provided for achieving efficient utilization of wheat resources and promoting practice of precise nutrition, and a theoretical basis and data support are provided for feed and breeding enterprises to scientifically design a daily ration formula of laying chicks.
