Рhysiological features of spermogram in males of different breeds of Russian selection

Abstract

 Dog breeding in Russia is developing in different directions: service dog  breeding, decorative dog breeding, sled dog breeding, hunting dog  breeding and others. For the first time in Russia, the physiological characteristics of the native sperm of dogs of various breeds of domestic selection have been studied. The volume of ejaculate was the highest in males of the Rottweiler breed, which is 3.34 ml more (p<0.05) from the Labrador breed, 4.78 ml more (p<0.01) from male German Shepherd Dogs, by 1.34 ml more from Dobermans, 6.89 ml more (p<0.001) from Welsh Corgi, 12.68 ml more (p<0.001) from Pomeranians, and 12.54 ml more (p<0.001) from Yorkshire Terriers. The best sperm activity was observed by us in the German Shepherd, which is 1.11 points more than the Labrador breed, 0.66 points better than the Dobermans, 3.33 points more  (p<0.001) from the Rottweilers, 2.55 points more (p<0.001) from Husky males, 0.33 points more from Welsh Corgi, 2.22 points more (p<0.01) from Pomeranian and 1.77 points more (p<0.05) males Yorkshire Terrier breed. The concentration  of sperm was the highest in males of the Welsh Corgi breed, which is 17.78 million more from the Pomeranian, 38.38 million more from the Yorkshire  Terrier, 257.66 million more (p<0.001) from the Labrador, 173,11 million more (p<0.01) from the German Shepherd, 152 million more (p<0.01) from the Dobermans, 196.44 million more (p<0.001) from the Rottweilers and 253 million more (p<0.001) from Husky males. The smallest number of pathological forms of sperm was noted by us in Yorkshire terriers, which is 1.22% less from the Pomeranian, 1.11% less from the Welsh Corgi, 8.05% less (p<0.001) from the Husky, 5,5% less (p<0.001) from Rottweilers, 3.05% less (p<0.01) from  Dobermans, 1.78% less (p<0.05) from German Shepherd males and 4.05 % less (p<0.001) from Labrador males.
