| dc.description | Modern problems of sheep breeding development put forward the need for in-depth research into the possibility of improving existing breeds of sheep, and first of all, the assessment of breeding and productive qualities of sheep. Thanks to such approaches, it is possible to achieve higher breeding rates of progress in the main characteristics of productivity quite quickly. The selection of indicators and their analysis was carried out based on the materials of the grading of the Tavrian type of the Ascanian fine-wool breed. The experimental groups were formed taking into account the indicators of the amount of fat (excellent, good, satisfactory) and their origin (lines 224, 369 and 0058). The aim of the work was to study the features of the productivity indicators of the Tavrian type of the Ascanian fine-wool breed, taking into account the origin and amount of fat, using the data obtained in the selection and breeding work with the breed. It was found that the highest live weight was in the ewes with an excellent amount of fat (50.2 kg), which is 0.4–0.5 kg more than in animals with a good (group II) and satisfactory (group III) amount of fat. No specific pattern of the advantage of ewes in live weight, taking into account the origin, was found. The yield of washed fiber in the experimental groups was 51.5–61.3%, which corresponds to breed standards and depends on the origin of the animals and the amount of fat. The shearing of washed wool is positively correlated with live weight: in ewes with a larger mass, a higher shearing was recorded. In the first group, it was 3.3 kg, which is 0.1 kg (3.0%) more than in the second group. The lowest yield of washed fiber in the first group was found in the yarks of line 369 – 58.9%, which is 2.4% less compared to line 0058 and 0.3% – with line 224. A similar trend was observed in other groups. The greatest length of wool was also noted in the first group of yarks – 11.8–12.7 cm. The difference with the second group was 0.7 cm (5.8%), and with the third – 0.3 cm (2.5%). No difference in wool thickness was found between the analyzed yarks. All wool was thin and classified as 64 quality. | ru |
| dc.description.abstract | Сучасні проблеми розвитку вівчарства висувають необхідність глибоких досліджень можливості вдосконалення існуючих порід овець, і в першу чергу оцінку племінних та продуктивних якостей овець. Завдяки таким підходам можна достатньо швидко досягнути вищих селекційних темпів прогресу за основними ознаками продуктивності. Вибір показників та їх аналіз проведено за матеріалами бонітування ярок таврійського типу асканійської тонкорунної породи. Дослідні групи було сформовано з урахуванням показників кількості жиропоту (відмінна, добра, задовільна) та їх походження (лінії 224, 369 та 0058). Метою роботи було дослідження особливостей показників продуктивності ярок таврійського типу асканійської тонкорунної породи з урахуванням походження та кількості жиропоту з використанням одержаних даних в селекційно-племінній роботі з породою. Встановлено, що найвищу живу масу мали ярочки з відмінною кількістю жиропоту (50,2 кг), що на 0,4–0,5 кг більше, ніж у тварин з доброю (ІІ група) та задовільною (ІІІ група) кількістю жиропоту. Певної закономірності переваги ярок за живою масою з урахуванням походження не виявлено. Вихід митого волокна в дослідних групах становив 51,5–61,3 %, що відповідає породним нормам і залежить від походження тварин та кількості жиропоту. Настриг митої вовни позитивно корелює з живою масою: у ярок з більшою масою зафіксовано вищий настриг. У першій групі він становив 3,3 кг, що на 0,1 кг (3,0 %) більше, ніж у ІІ групі. | ru |
