The transplant fish production method includes selecting a donor fish species, selecting first and second fish species which are a combination that could be sterile, producing a hybrid fish species of the selected first fish species and second fish species, and transplanting reproductive cells of the donor fish species into the produced hybrid fish species.

The invention provides a selecting method for domestic rabbits with a agouti/Belgian hair color based on homozygous genotype selection. The purification method is applicable to purification of various domestic rabbits with the agouti/Belgian hair color. The method includes the following steps: firstly, selecting the domestic rabbits with a hair color phenotype which is the agouti/Belgian hair color; then detecting an ASIP gene, a MC1R gene and a TYR gene at the same time by utilizing a first primer set, a second primer set and a third primer set; screening the domestic rabbits with genotypes of AA (corresponding to the ASIP gene), EE (corresponding to the MC1R gene) and CC (corresponding to the TYR gene). The domestic rabbits with the genotype of AAEECC, which are obtained by the screening method of the invention, are agouti/Belgian hair color homozygotes and the recessive white gene is eliminated.

A method for micro-ridge mixed-sowing cultivation of dryland crops includes the following steps: S1: cleaning ditches and draining away water in dryland; S2: harvesting the preceding crop, leaving the stubble, smashing the stalks of the preceding crop, and then spreading the smashed stalks on the stubble; S3: trenching the dryland to form ecological trenches; S4: flattening the standing stubble and the smashed stalks on the seedbed surface to form an underlying surface, molding seed-fertilizer-soil compounds into a ridge shape and allowing the seed-fertilizer-soil compounds to fall on the underlying surface to form ecological ridges, wherein a plurality of ecological ridges are formed between adjacent ecological trenches, an ecological depression is formed between adjacent ecological ridges, and after sowing, an irrigation is carried out, including: draining water shortly after the irrigation, without leaving a water layer in the field.

Method and kits for diagnosing propensity to non-contact cranial cruciate ligament rupture (CCLR) in a dog are described. The method includes isolating genomic DNA from a dog and then analyzing the genomic DNA from step for a single nucleotide polymorphism occurring in selected loci that have been determined to be associated with the CCLR phenotype via a genome-wide association study.

The present invention relates to industrial animal production. In particular the present invention relates to a method of raising a group of animals, and a method of determining analytes, in egg yolk or in the blood of an animal by ex vivo analysis of blood and/or yolk samples.

Method and systems for measuring growth rate in plant or aquatic animal species such as embryonic or adult fish. The methods and systems utilize the measurement of NADH.sub.2 production by detecting a colorimetric and fluorescent shift when a redox indicator such as resazurin is added to a sample. The colorimetric/fluorescent shift is indicative of the reduction of the redox indicator by NADH.sub.2. The methods and systems of the present invention may be used to predict growth potential of a plant or animal, and measuring the growth rate of said plant or animal may be helpful for identifying and selecting individuals within a group that have greater growth potential. The methods and systems of the present invention may help eliminate the need for special equipment (e.g., for measuring oxygen consumption), decrease variability of measures, and minimize the effects of external factors (feeding/hormonal status).
