Abstract. The aim of the research is to study the selection and genetic parameters of the characteristics of productivity and the exterior of Holstein first-calf cows, depending on their body type. Research methods. Based on the data from the SELEX database, we researched the performance indicators and measurements of the trunk of first calving cows in the amount of 4049 heads. Based on the RENUMF90 software shell of the BLUPF90 program, we obtained digital values of the genetic variability of productivity indicators and the external structure of animals in accordance with the equation of the mixed model. Results. The most broad-bodied animals classified as airysomal type had the highest milk yield in the first lactation, and exceeded animals of the leptosomal type by 563.3 kg (p ≤ 0.001). According to the "B" system, broad-bodied cows are superior to narrow-bodied animals: stature – by 1 point (p ≤ 0.001); body depth – by 0.8 points (p ≤ 0.01); rump width – by 1.9 points (p ≤ 0.001); rump angle – by 0.9 points (p ≤ 0.01); fore udder attachment – by 1 point (p ≤ 0.01). Animals of the narrow-bodied type reliably (p ≤ 0.001) had a high genetic relationship between milk yield in 305 days of first lactation and the mass fraction of protein in milk (0.59 ± 0.005). At the same time, the leptosomal type of cows also had the greatest correlation between milk yield and mass fraction of fat (0.51 ± 0.005) (p ≤ 0.001). According to body measurements, the highest correlation coefficients were found in animals of the airysomal type – 0.24 ... 0.50. All Holstein heifers of different body types have high heritability coefficients in terms of fat mass fraction (h2 = 0.37 ... 0.49) and protein mass fraction (h2 = 0.42 ... 0.51). Scientific novelty. For the first time, studies of the genetic variability of productivity indicators and the exterior of Holstein cows, depending on their body type, were conducted.
Exterior assessment is important for specification of constitutional strength of an individual animal and its acclimatization ability, as well as its productive orientation. The object of our research was Holstein first-calf heifers of the black-and-white breed prevailing on the farms of Moscow region. Studies were conducted with application of linear estimation of the animal body type of 54,170 animals. Animals are divided into 5 groups depending on the lineage: Vis Back Ideal 1013415, Reflection Sovering 198998, Pabst Governer 882933, Montvik Chieftain 95679 and other lines. Most of the animals had parameters in the range of 4 ... 6 points. With greater reliability (p≤0.001) and in the course of the dispersion analysis, it was found that it affects the rump bone height, position of the quarters, the height of the back lobes, the length of the nipples, the width of the quarters and the angle of the back legs from the side (p≤0.01). The heritability of the rump bone height (0.27 ... 0.38) and milk type (0.16 ... 0.36) in almost of all studied lines was within moderate limits. A high occurrence of such constitutional defects as soft ankles (4.16 ... 13%), oblique udder bottom (1.78 ... 5.02%), high tail (2.75 ... 8.07%) and roof-like quarters (1.08 ... 3.77%) was noted in such lines of first-calf heifers as Vis Back Ideal 1013415, Reflection Sovering 198998 and Montvik Chieftain 95679. Animals of all the studied groups have high genetic correlations between the rump bone height and other parameters of constitutional assessment: Montvik Chieftain line has 95679 positive pairs 8 ( 0.63 ± 0.0032 ... 0.97 ± 0.0005) and 5 negative pairs (-0.66 ± 0.0041 ... -0.97 ± 0.0045); Vis Back Ideal 1013415 - 2 positive pairs (0.48 ± 0.0007... 0.66 ± 0.0006); Reflection Sovering 198998 - 4 positive pairs (0.41 ± 0.0009 ... 0.62 ± 0.0007); Pabst Governer 882933 - 3 positive (0.55 ± 0.0092 ... 0.74 ± 0.0071) and 2 negative pairs (-0.62 ± 0.0174). The obtained results reveal wide selection possibilities in dairy herds.
Abstract. The purpose of the research – to study the impact of related foreign pedigree resources on the Russian population of Simmental cattle. Research Methods. Studies carried out on cows of Simmental breed of different linear origin and genotypes in five regions of Russian Federation: Voronezh, Oryol, Kursk, Belgorod regions and Altayskiy krai, the total number was 35147 cows. EBV estimates were calculated through RENUMF 90, REMLF 90 and BLUPF 90 programs. Evaluation of the components of the variants of genetic and paratypical nature was carried out using the method restricted maximum likelihood – REML. Results. It is established that the largest share for animals foreign origin are 60.7 %, including German-Austrian bloodlines 46.6 % and Holsteins – 14.1 %. 39.3 % of animals are the Russian origin, which 13.5 % representatives of German-Austrian bloodlines, 17.8 % are Holsteins and 8.0 % are from domestic (Russian) bloodlines. In the general population of Simmental breed, the best productivity was shown by cows of German-Austrian bloodlines at the level of 5351 kg of milk with fat percentage 4.00 % and protein percentage 3.19 %. Representatives of German-Austrian bloodlines origin for milk yield showed the estimated breeding value (EBV) for Simmental bulls in the common population by +9.2 kg and fat percentage by +0.012 %. The negative EBV values were obtained for Russian bloodlines by –22.8 kg, and Holstein bloodlines took an intermediate position among all lines (+2.3 kg). The first calving cows, which were in the herd at the time of research, the best milk production traits were found in individuals of foreign origin, both for Holstein (6096 kg of milk with a fat content of 3.96 % and protein 3.23 %), and German-Austrian bloodlines (milk yield 5763 kg, fat 4.04 % and protein 3.19 %), with high estimates of breeding value for milk yield +33.3 kg and +15.2 kg, respectively. Low values of milk productivity among all evaluated animals were observed for animals of Russian bloodlines by 4469 kg milk 3.87 % fat and 3.20 % protein in milk. The first calving cows of Russian origin in foreign bloodlines origin exceeded their peers in Russian Simmental bloodlines in milk production by +608 kg of milk and +0.15 % fat (signed to German-Austrian bloodlines) and +924 kg and +0.06 % fat (signed to Holstein bloodlines). The average values of EBV in these lines, although had low values by –5.6 kg milk for Holstein and by +2.7 kg milk for German-Austrian bloodlines, but was significantly higher than for Russian lines by –12.7 kg milk. Scientific novelty. For the first time, scientific research aimed at improving the system of prediction to breeding abilities of bulls on dairy productivity of daughters based on optimization structure of equations of the mixed model (BLUP, the best linear unbiased prediction) has been carried out for the population Simmental cattle of Russian Federation.
