The application belongs to the technical field of animal feed, and particularly relates to an egg-laying chicken feed without soybean meal, and a preparation method and application thereof. The method comprises the following steps: S1, mixing wheat flour, barley flour, cottonseed meal and glutamic acid residue, crushing the granules to obtain broken material; and S2, mixing the broken material with corn, sunflower meal, corn gluten meal, pepper residue, granular stone powder, calcium hydrogen phosphate, soybean oil, compound enzyme, sodium chloride, sodium bicarbonate, egg methionine, lysine sulfate and threonine to obtain the egg-laying chicken feed without soybean meal. The application provides comprehensive essential amino acids, especially limiting amino acids such as lysine, egg methionine and threonine, by the synergistic combination of cottonseed meal, sunflower meal, corn gluten meal and glutamic acid residue, so as to meet the nutritional requirements of egg-laying chickens. The application granulates at a temperature of 75-85 DEG C, effectively degrades free gossypol in the cottonseed meal, reduces the content of free gossypol to less than 30 mg / kg in the finished feed, and eliminates the adverse effects on the health of egg-laying chickens.

The present application relates to the technical field of molecular biology, and particularly relates to a broiler liquid chip based on targeted capture sequencing and application thereof. The 50K liquid chip for broiler prepared by using the SNP molecular marker combination provided by the present application has the following advantages: 1) optimization design: the whole genome is uniformly distributed on each chromosome, the coverage is high, and the accuracy of the genetic evaluation of the broiler genome is ensured; 2) functional correlation: the chip collects significant sites related to the production performance, disease resistance traits, feed utilization efficiency and other traits of the broiler, and the practicability of the chip is increased; 3) applicability: the chip sites are derived from the high polymorphism SNPs in the commercial high-yield egg-laying chicken breeds and Chinese local breeds, which not only meet the research needs of researchers, but also meet the whole genome molecular breeding work of egg-laying chicken enterprises; 4) flexibility: the liquid chip technology has great advantages in the aspects of analysis speed, sensitivity, throughput and the like.

This invention discloses a method related to chicken egg production. GTF2A1 This invention relates to molecular markers of SNPs in intron regions of genes and their applications, belonging to the field of molecular genetics. Specifically, it focuses on SNPs on chicken chromosome 5. GTF2A1 Four SNP loci, 5_41037360, 5_41038069, 5_41044660, and 5_41044663, were detected in the 4th, 7th, and 8th intron regions of the gene. Detecting these four molecular markers associated with egg production is not only a simple and quick method, but also helps in the breeding of early-maturing, high-producing egg-laying chicken breeds, providing valuable assistance for breeding work.

The application discloses a kind of oligogenic chicken phenotype feature detection and identification method based on multimodal large model, it is related to computer vision and artificial intelligence technical field, including: obtaining the image data and day age of cage chicken to be identified in henhouse;With the input of the pre-training oligogenic chicken accurate identification multimodal large model, the image data and day age of cage chicken to be identified and the related problem text of oligogenic chicken identification, obtain the identification result and coordinate of oligogenic chicken.The application realizes the efficient, high-precision oligogenic chicken identification in large-scale henhouse, provides a theoretical basis for realizing the oligogenic chicken accurate identification function of large-scale henhouse inspection robot, helps to promote the wide application of inspection robot in large-scale henhouse, provides key technical support for egg poultry intelligent breeding.

The invention relates to the field of chicken manure treatment, in particular to an automatic chicken manure collection and pretreatment device for laying hen breeding. The automatic chicken manure collecting and pretreating device for laying hen breeding comprises a collecting and screening box and a solid-liquid separating and squeezing box. A connecting frame is fixedly installed at the bottom of the collecting and screening box, the solid-liquid separation squeezing box is connected with the collecting and screening box through the connecting frame, and the discharging end of the collecting and screening box corresponds to the feeding end of the solid-liquid separation squeezing box. Wherein the collecting and screening box is internally provided with a scattering and screening assembly, and the scattering and screening assembly is used for beating the chicken manure entering the collecting and screening box so as to separate leachate entrained in the chicken manure. According to the automatic chicken manure collection and pretreatment device for laying hen breeding, an electric push rod of the scattering and screening assembly drives a toothed plate to drive a gear, a rotating shaft and a stirring and scattering plate to synchronously act, chicken manure is evenly beaten, percolate falls off through a filtrate hole and is collected in a centralized mode through a guide plate, percolate residue or accumulation is avoided, and the quality of chicken manure is improved. And a foundation is laid for subsequent resource utilization.
