Structure And Functions

The accumulation of knowledge about the structure and functions of the epidermis will make it possible to solve the most important practical tasks of forming the animals’ productivity and health. Two breeding groups have been researched: 1) purebred young boars, 2) young boars with the blood of Finnish Landrace. The studies were carried out when the animals reached live weight of 100 kg, and the control slaughter was made. The results of the Poltava Meaty Breed pigs’ skin epidermal barrier research made it possible to trace significant differences in the ratio of the main epidermis layers in animals of different genotypes. The genotype influence was 15.45 %. An-imals with the blood of the Finnish Landrace have lower biological possibilities for life in the given climatic and technological conditions, that is, they are less promising for further breeding work.

The purpose of the research, the results of which are revealed in the article, was to develop methodological approaches for calculating the genetic potential of productivity in pig breeding. The research was carried out in a breeding facility for animal breeding FG "Shubske", Bogodukhiv district, Kharkiv region. At the first stage, the productivity of the offspring (fattening qualities) of the UNI family saws of Welsh breed in the breeding facility for FG "Shubske", Bohodukhiv district, Kharkiv region was evaluated for two consecutive generations. The results show that in general for all evaluated uteri, there was a reduction in the fattening period by 0.60 days with a reduction in feed consumption by 0.04 feed units. At the same time, the thickness of the fat on the estimated family at the level of two estimated generations there was a regression of 0.10 mm. According to the obtained data, methodological approaches that are effective in direct indicators (reproducible qualities, slaughter qualities, etc.) turned out to be uninformative in inverse indicators, where it is desirable to reduce values (age of live weight, feed consumption, fat thickness, etc.). It is proposed to use the given formulas only for direct indicators, and for inverse indicators to use formulas for a slightly modified mathematical apparatus. Considering these features, a modified methodological approach to the calculation of this indicator by inverse indicators is proposed. Using this methodological approach, the calculation of the genetic potential of productivity by fattening qualities was carried out and the degree of realization of the genetic potential of animal productivity was determined. According to the results of the assessment of the genetic potential of productivity (according to the proposed methodological approach) of the fattening qualities of the offspring, the sow B19056 was was marked by the highest values of the genetic potential of productivity. Also, without considering the values of lifelong fat thickness in the offspring, for further breeding work, based on the assessment of the genetic potential of productivity, sows B19004 and G19308 can be used.

Large White × Pietrain boars were administered 0 or 5 mg recombinant porcine somatotropin (pST) daily between 68 and 105 kg live weight in an investigation of the effects of pST treatment on growth performance, carcass traits, genital-tract development, steroid-hormone synthesis, and fat skatole and androstenone levels in young male pigs. Growth rate was not affected by pST treatment, daily feed intake was decreased 9% (P < 0.05), and feed efficiency was improved 7% (P < 0.01). Muscle content of the carcass was increased from 57.7% to 59.7%, and fat content was reduced from 18.8% to 15.7% (P < 0.001). Genital-tract development, testicular androgen and 16-androstene biosynthesis rates and skatole levels in fat were not affected by pST treatment. Androstenone levels in fat were reduced from 0.66 μg g−1 in control animals to 0.35 μg g−1 in pST-treated animals (P < 0.001). The results of the present experiment indicate that pST treatment of boars of a lean genotype significantly improves the performance of the animals and may contribute to a reduction in the incidence of boar taint.

Breeding Groups

The assessment of black-and-white, red steppe, and Simmental cattle, differentiated by milk fat was carried out. Three groups were formed: selection, production and marriage. The selection parameters are calculated using the standard deviation. The calculated parameters of selection of animals of the breeding group for milk fat in adult black-and-white cows are at least 179 kg, red steppe - 186, Simmental breed from the Novosibirsk region - 143, the Republic of Khakassia - 176 kg. Cows of the red steppe breeding group are leading in productivity. Their milk fat index is 216.8 kg (P ≥ 0.95). In animals of the black-and-white breed, the milk fat productivity is 193.2 kg. In the Simmental Republic of Khakassia it is 193.8, in the Novosibirsk region - 163.5 kg. Analysis of interbreed differences in cows of breeding groups shows that animals of the black-and-white breed surpass their peers in chest width behind the shoulder blades, milk yield and milk production index. Animals of the red steppe breed are the best in milk fat, live weight, width in shanks, oblique body length, oblique rear length, chest girth, milk fat content. Simmental cows bred in the Novosibirsk region lead over their peers in height at the withers, and Simmental cows in Khakassia - in height at the sacrum, chest depth, cannon girth, assessment of the exterior. Evaluation of the production groups of animals for milk fat allows to note that the selection group of the black-and-white breed, despite the superiority in milk yield, is inferior to the peers of the red steppe and Simmental in terms of the evaluated character. However, the cows of the black-and-white breed of the production group surpass their peers in milk fat and most other signs. The formation of breeding groups for milk fat enables to note the consolidation of the black-and-white breed in terms of productive and exterior characteristics. The Red Steppe and Simmental breeds have a high potential for improvement. These breeding groups are worthy of competing with the contemporaries of the black-andwhite breed in milk fat productivity.

Assessment Results

The article presents assessment results of red-and-white breed lines on milk productivity, live weight and intensity of milk yield. It was found that almost all the descendants of the bulls belonging to the lines of V.B. Ideal 1014315, M. Chieftain 95679, R. Sovering 198998, R. Citation 267150 are characterized by high milk yield. The only exception was the daughters of the bulls from R. Sovering 198998 line, who were inferior to their peers in milk yield by 225-250 kg (4.1-4.5%) during 305 - day lactation. There were no significant interline differences in the content of fat and protein in milk. It was found that positive results were obtained from crosses of V.B. Ideal × M. Chieftain (+204 kg of milk), M. Chieftain × V.B. Ideal (+300 kg), M. Chieftain × R. Sovering (+185 kg), R. Sovering × R. Sheilimar. Intraline selection on milk yield in all cases was ineffective. Assessment of servicing bulls of V.B. Ideal line showed that the improvers of the daughters’ milk yield are the bulls Kumir 1242 (+283 kg to their peers), Leonardo 218 (+244 kg), Jul 43 (+143 kg). Bulls Clemens 12700 (- 201 kg) and Furgon 1268 (- 679 kg) were recognized as deteriorating the milk yield. As for R. Sovering line, the bulls Service 101 (+403 kg) and Mills 284 (+263 kg) are the milk yield improvers, and the bull Berkut 3473 (+0.38%) improves fat content of milk of the daughters.

The study presents the results of many years of breeding work on the creation of a new breed of sable – «Saltykovskaya silver». The breed is consolidated in color and hair quality. To date, the level of selection on the basis of gray hair is assessed as stabilizing. The live weight of females of the main herd is 1,2 kg, males 1,9–2,3 kg. The average values of fertility and yield of puppies in females of the breed «Saltykovskaya Silver» are at the level of the highest values for the species. The stability of reproduction indicators is shown both according to the data of safely whelping females and indicators of the average number of puppies per main female over a number of years. The new breed will improve the competitiveness of domestic fur in international markets.

Significant Factors

SUMMARYThe incidence of swayback among lambs in two flocks, previously reported, was reanalysed by a specially developed modification of the probit analysis technique in order to allow for the joint complications of an all-or-none trait and a large number of possible classifications for the animals in each flock. The form of analysis described yields predictions of the probability of swayback among lambs for the given circumstances.Breed and sire within breed each affected the probability appreciably even when allowance for live weight of ewe and lamb was made. The effects of live weight, though significant in each flock, were not consistent in direction between the flocks. Other significant factors affecting swayback incidence were the manner of rearing the lambs, week of birth, and, in one flock, the sex of the lamb.

Concern is being expressed about the marketing of over-lean carcasses, especially from young boars. Experiments at Terrington have tested the effects of various management practices, feeding regimes and slaughter weights on the performance and backfat thickness of young boars reared for meat production.Pigs were kept in groups of mixed castrates and gilts, mixed boars and gilts, gilts only and boars only. Start of test was about 35 kg live weight and three different slaughter weights were selected to represent the main carcass types: cutters — 81 kg, baconers — 93 kg and heavies — 110 kg live weight. Backfat thickness increased with age, weight at slaughter and total feed consumption. Feed consumed by boars was 140 kg for cutters, 181 kg for baconers and 250 kg for heavies. P1, + P3 (mm) of boars was 23.7, 25.9 and 32.6 for the three slaughter weights, respectively.
