Abstract

Introduction. In the structure of meat cattle breeding in Ukraine already a long time the leader in the number among of breeds of foreign origin there is a Aberdeen-Angus. This breed, due to its high manufacturability, is intensively used as a genetic material in the breed-forming process and increase the production capacities of the pedigree base of cattle breeding.

At one time, the most intensive works on the development of the breed was conduct on the basis of the SAE "Main Breeding Center of Ukraine". Thanks the validity state support was organized the estimating of bulls for their own productivity and quality of descendants, was formed a bank of deep-frozen sperm and embryos, were created informative electronic card indexes of individual data of pedigree animals. This determines the expediency of analyzing the features of the formation of the genealogical structure of the population of the Aberdeen-Angus breed on the basis of the study of individual herds, which becoming the purpose of this work.

The purpose of this work was to investigate the genealogical lines and families in the herd of Aberdeen-Angus breed in SAE "Main Breeding Center of Ukraine".

Research materials and methods. The study of the genealogical structure was carried out on the basis of data primary zootechnical accounting in the format of SMDC "Orsek-M", expeditionary examination of the herd and the results of a comprehensive individual estimating of animals.

Biometric processing of data was carrying out according to the method of N. A. Plokhinsky with using the software Microsoft Excel.

Research results. As of 01.01.2021 year, in the herd of the enterprise total accrued of 155 heads, including 84 cows, which now fertilization of the method of natural mating bulls, purchased from the LLC “Ratnivsky Agrariy”, which obtained by method of artificial insemination of high-producing cows of the 2nd and older calves sperm of bull of Team Z Pecina 4031.

Now the uterine stock of the studied herd belongs to the lines Southom Extr – 29 heads, Raito Iver 865 – 18 heads, Villabar 85 – 8 heads, Raito B 1567126 – 7 heads, Vetonk 2446 – 5 heads, Ilinmer Led 173 – 4 heads, Brialhill Sauzerner – 2 heads and the related group Team Z Pecina 4031 – 11 heads.

The age of cows fluctuated from 3.1 to 19.2 years, and in the average be 9.8 years. The oldest cows belongs to the lines Raito B 1567126, Brialhill Sauzerner and Ilinmer Led 173, the youngest – to the related group Team Z Pecina 4031 and to the line Vetonk 2446.

In the studied herd total detected 23 potential ancestors, which have living descendants of female sex. The most numerous are the families of K. Pride 11212597 – 9 descendants, E. Pride 11153487 – 8 descendants, K. Vessi 10887560 – 7 descendants. The families of Erika 3200797288, Kornela 3200797248, Sara 11756665 and Sandy 951931 presented 5 descendants of female sex of different generations.

The minimum age of more than 10 years have the representatives of families of K. Erika 10240733, Beauty 10767437 and Elbe 3200797255, and the maximum age from 18 to 19.5 years – the representatives of families of K. Erika 10240733, Elin 10679739, E. Pride 11153487, Gemmer 10189403.

The lowest and the highest average live weight had the newborn heifers the family of Kornela 3200797248 – 24.0 ± 1.7 kg, and the family of E. Pride 11153487 – 33.2 ± 1.5 kg, respectively. The average live weight of newborn heifers in other studied families was following: K. Pride 11212597 – 25.1 ± 0.4 kg; Erika 3200797288 – 28.6 ± 1.6 kg; K. Vessi 10887560 – 29.5 ± 1.5 kg; Sandy 951931 – 30.4 ± 1.6 kg.

The average daily gain of live weight of heifers for the period from birth to 12 months of age fluctuated from 615 to 750 grams. The highest and the lowest average live weight at 12 months had the heifers the family of E. Pride 11153487 – 307.0 ± 19.7 kg and the family of K. Pride 11212597 – 249.2 ± 8.5 kg, respectively. Almost identical average live weight had the heifers the families of K. Wessie 10887560 and Kornela 3200797248 – 266.1 ± 11.14 kg and 266.6 ± 6.1 kg, respectively.

The age of the first insemination fluctuated from 17.6 months in heifers the family of Erika 3200797288 to 21.4 months in heifers the family of K. Vessi 10887560. The highest average live weight at the age of the first insemination had the heifers the family of Sandy 951931 – 364.7 ± 20.6 kg, and the lowest – the heifers the family of Erika 3200797288 – 303.0 ± 8.8 kg, due to the younger age of their first insemination.

Conclusions. Considerable narrowing of the genealogical structure of the modern herd of Aberdeen-Angus breed in SAE "Main Breeding Center of Ukraine" provoke the full absence representatives such classical lines as Ideal 3163, Power Play 8974207 and Showshoun 548. Due to the expansion of the related group Team Z Pecina 4031 will increase the genetic variability, reorganize age structure the uterine stock and direct zootechnical work with families to improve the parameters of individual growth and development of animals.
