The application provides a method for optimizing the slaughter weight of Jinfen white pigs to produce high-quality flavor pork. Through systematic research on the influence of different slaughter weights on the pork quality and flavor of Jinfen white pigs, it is first determined that when the slaughter weight is 135.08±1.10 kg, the pork has the optimal comprehensive quality performance, which is specifically embodied in that the intramuscular fat content reaches (3.82±0.05)%, the shear force is (35.75±1.68) N, and the meat quality is excellent. At the same time, the pork of the weight group has the most total volatile substances, and the types of various volatile substances are relatively rich, and exhibits the best flavor characteristics. The application not only provides clear process parameters for the production of high-quality flavor pork of Jinfen white pigs, but also provides a reliable technical basis for the precise regulation of meat quality based on the slaughter weight.

The invention belongs to the technical field of animal feeds, and discloses a high-utilization-rate yellow feather chicken feed and a preparation method thereof. According to the present invention, by optimizing the formula of the complex enzyme preparation, the high utilization rate yellow feather chicken feed suitable for different growth stages is provided, and comprises a 1 # feed used for the 0-21-day-old stage, a 2 # feed used for the 22-42-day-old stage, and a 3 # feed used for the 43-slaughter stage. Compared with the traditional corn cottonseed meal type daily ration, the yellow feather chicken feed provided by the invention has the advantages that the dry matter digestibility and crude protein digestibility are higher than those of the traditional corn cottonseed meal type daily ration, in addition, the average body weight after slaughtering is higher, and the feed conversion ratio is lower. The feed has contribution significance in reducing feed waste, improving the health condition of the yellow feather chickens, reducing the feeding cost and the like.

The disclosed technology includes systems and methods for continuously supplying livestock to a processing plant. The disclosed technology can include an enclosure configured to house livestock. The enclosure can include an enclosure entrance, an enclosure exit, and moveable walls to partition the enclosure into separate pens and automatically direct the livestock from the enclosure entrance toward the enclosure exit. A passageway can be connected to the enclosure exit and include moveable walls to automatically direct the livestock from the enclosure exit toward a processing plant. The moveable walls can be configured to move at a predetermined speed such that the plurality of livestock enter the enclosure as offspring, are reared in the enclosure, and are directed through the enclosure exit into the passageway approximately when the plurality of livestock have reached slaughter weight.

The present application relates to the technical field of poultry breeding, in particular to a breeding method for precisely increasing the proportion of chicken wings and chicken claws. The breeding method provided by the present application is in line with the demand characteristics of the Chinese consumer market, follows the laws of genetics, and realizes the fine breeding of chicken claw and chicken wing traits through fine determination of the phenotypes of related traits, accurate estimation of individual breeding values, and scientific selection and mating methods. Under the premise of ensuring growth rate, slaughter weight and feed conversion rate, the weight and proportion of chicken wings and chicken claws are effectively increased, meeting the consumer demand for chicken wings and chicken claws in the Chinese market.

The invention discloses an SNP (Single Nucleotide Polymorphism) site related to the slaughtering weight of a rabbit at the age of 70 days and application, and belongs to the technical field of molecular marker-assisted breeding. The SNP site is located at 129803bp of chromosome 3 of a reference genome of the Kangbig meat rabbit, and the polymorphism of the SNP site is T / G. According to the SNP locus and the detection method provided by the invention, an efficient and accurate molecular marker-assisted breeding technology can be established, and when the molecular marker-assisted breeding technology is applied to genetic improvement of the marketing body weight character of the breeding rabbits at the age of 70 days, the breeding period can be shortened, the feed cost can be reduced, the marketing efficiency can be improved, and the overall benefits of rabbit breeding can be further improved.

The invention relates to the technical field of livestock breeding, in particular to a live pig growth monitoring integrated feeder which comprises a feeding box, a material level sensor is fixedly installed on the inner top wall of a material storage groove chamber, an air cylinder seat is fixedly installed at the bottom of the material storage groove chamber, and a tension sensor is fixedly installed at the top of a main frame rod. The exterior of the lifting rod is rotationally connected with a linkage rod piece, and the bottom of the hanging rod is fixedly connected with a weighing plate. According to the pig growth monitoring integrated feeding device and the management system, the RFID reader-writer detects and identifies specific ear tag information of different individual pigs, a feed intake threshold value is set for each pig through the control system according to the growth conditions and marketing weight threshold values of the individual pigs, the RFID reader-writer reads the feed intake threshold values in the system, and the RFID reader-writer sends the feed intake threshold values to the feeding system. The air cylinder seat is adjusted to control the opening time of the material blocking plate, the quantitative feed amount is determined, weight detection of the pigs in the stable feeding state is conveniently achieved, and the situation that stress behaviors of the pigs are caused by a traditional constraint method is avoided.

This invention provides a combination of SNP molecular markers for pig carcass traits, a method for polymerase chain breeding, and its application, belonging to the field of molecular marker technology. This invention provides three SNP loci that influence slaughter weight, carcass length, and backfat thickness in pigs. Individuals with the GG genotype at SNP1, the CC genotype at SNP2, and the AA genotype at SNP3 exhibit higher slaughter weight and carcass length, but relatively lower backfat thickness. By accurately identifying the genotypes of these three loci and their specific combination GG-CC-AA, it is possible to efficiently screen for high-lean-percentage breeding pigs with large slaughter weight, long carcass, and thin backfat. This provides a scientific and reliable molecular marker basis for pig breeding, accelerates the selection process for high-lean-percentage breeding pigs, helps meet market demand for high-quality pork products, and promotes the efficient, high-quality, and sustainable development of the pig industry.

The invention discloses a molecular marker related to marketing weight of cocks, a primer pair and application of the molecular marker and the primer pair, and belongs to the technical field of molecular marker-assisted breeding. The invention discovers that an SNP (Single Nucleotide Polymorphism) site obviously related to the marketing weight character of the cock exists at the chr1: 8081997. A molecular marker and a specific primer are designed according to the site, genetic typing is carried out on the target site through a PCR amplification technology and a sequencing technology, cock individuals with dominant marketing weight traits can be accurately screened out, and the method can be used for early screening and breeding reservation of the cock individuals with the dominant marketing weight traits.
