Research Results

The article presents the results of research on the reproductive qualities of sows of different breeding value, as well as determines the economic efficiency of their use in the industrial complex. The study was conducted in agricultural formations of the Dnipropetrovsk region (LLC "Druzhba-Kaznacheyivka", LLC "Vidrodzhennia") and the laboratory of animal husbandry of the State Institution Institute of Grain Crops NAAS. The work was performed according to the research program of NAAS №30 "Innovative technologies of breeding, industrial and organic production of pig products" ("Pig breeding"). Evaluation of sows on the grounds of reproductive qualities was carried out taking into account the following indicators: fertility, head; high fertility, kg, number of piglets at weaning, head, nest weight at the time of weaning at the age of 28 days, kg, nest weight at the time of weaning at the age of 60 days (estimated), kg, safety, %. The breeding value of animals was determined by the multiplicity and weight of the nest at the time of weaning (according to Annex 7 of the Instructions for grading pigs) and the selection index of reproductive qualities of sows (SIVYAS). The index of alignment (homogeneity) of the sow's nest by live weight of piglets at the time of their birth (ІВГ0) was calculated according to the method of V.I. Khalak (2012), the economic efficiency of research results - according to conventional methods. Biometric processing of research results was performed according to the methods of G.F. Lakin (1990). It was found that sows of the "elite" class were superior to peers of the "extracurricular" class in terms of multiplicity, several piglets at weaning, nest weight at weaning at 28 days and nest weight at weaning at 60 days (estimated) by an average of 28, 76%. The difference between sows of classes M + and M- (distribution class for SIVYAS) in terms of multiplicity, number of piglets at the time of weaning, the weight of the nest at the time of weaning at the age of 28 days and weight of the nest at the time of weaning at the age of 60 days (estimated) is 34.32. 34.78, 27.60 and 28.30 %, respectively. The coefficients of pair correlation between the absolute indicators of reproductive qualities of sows, the index "alignment (homogeneity) of the sow's nest by live weight of piglets at birth" and the selection index of reproductive qualities of sows (SIVYAS) at 83.33-100.0 % are reliable from -0.446 to +0.989. The criterion for the selection of highly productive animals according to the Instructions for grading pigs is the class "elite", according to the selection index of reproductive qualities of sows (SIVYAS) - 97.85-123.99 and more points. The use of sows of the class "elite" and М+ (according to SIVYAS) provides additional products at the level of +11.84 - 16.49 %.

The article presents the results of studies of indicators of reproductive qualities of sows of large white breed of various intrabreed differentiation according to some evaluation indices, the criteria for selecting highly productive animals and the economic efficiency of their use are determined. On the basis of experimental data, аppendix 10 to the Instruction on the grading of pigs (correction factor for correcting the weight of the piglet nest at weaning at 60 days of age) has been modified and a new method has been developed for assessing sows according to the indicator "uniformity (uniformity) of a sow's nest in terms of live weight of piglets at weaning time" (IVG60). The studies were carried out in the «Druzhba - Kaznacheevka» JLLC in the Dnepropetrovsk region and the animal husbandry laboratory of the State Institution Institute of Grain Crops of the NAAS. The work was carried out in accordance with PSR NAAS No. 30 “Innovative technologies for pedigree, industrial and organic production of pig products (“Pigbreeding”). The assessment of sows in terms of reproductive qualities was carried out taking into account the following characteristics: multiple fertility, head, large fertility, kg, number of piglets at weaning time, head, nest weight at weaning time, kg (actual), nest weight at weaning time of 60 days, kg (calculated), safety, %. A comprehensive assessment of sows in terms of reproducti-ve qualities was carried out according to breeding indices of reproductive qualities of sows (SIVKS) (A. N. Tserenyuk et al., 2010), the index of N.D. Berezovsky (cited by P. A. Vashchenko, 2019), biometric processing of research results – according to the methods of G. F. Lakin (1990). It was found that 26.4 7 % of sows of the controlled herd, according to the characteristics of reproductive qualities (abundance, head, nest weight at the time of weaning at the age of 60 days (calculated), kg) belong to the elite class, 65.44 – I class, 7.35 – II class. The number of animals, according to the average score, are categorized as "out of class" is 0.73 %. The multiplicity of sows is 11.1 ± 0.15 heads. (Cv = 15.76 %), large fruit – 1.41 ± 0.009 kg (Cv = 7.88 %), the number of piglets at weaning time – 9.7 ± 0.13 head (Cv = 16.60 %), weight nests at the time of weaning, kg (actual) – 74.3 ± 0.85 kg (Cv = 13.48 %), weight of the nest at the time of weaning in 60 days, kg (calculated) – 175.9 ± 2.160 kg (Cv = 13.43 %), safety – 87.9 ± 0.49 % (Cv = 6.84 %). The index of uniformity (uniformity) of a sow's nest in terms of live weight of piglets at the time of birth is 5.21 ± 0.076 points (Cv = 17.11 %), at the time of weaning – 8.32 ± 0.156 points (Cv = 21.98 %), selection sow reproductive qualities index (SIVKS) – 88.31 ± 1.118 points (Cv = 14.77 %). Coefficients of pair correlation between the estimated indices IVG0, IVG60, SIVKS and signs of reproductive qualities range from -0.438 (index of uniformity (uniformity) of the nest of a sow in terms of live weight of piglets at the time of weaning, point (IVG60) × large fruit) to + 0.988 ± 0, 0020 (breeding index of reproductive qualities of a sow (SIVKS) × multiple pregnancy). The maximum increase in additional products received from animals of class M+ – 27.60 %, and its cost is equal to 685.33 UAH/head. Key words: sow, reproductive qualities, integrated assessment, evenness (uniformity) of the nest, variability, correlation, economic efficiency.

The paper presents the results of the study of signs of long-term adaptation and indicators of reproductive qualities of sows of the universal direction of productivity, as well as calculates the economic efficiency of research results. The experimental part of the work was performed in the agricultural formations of the Dnipropetrovsk region and the laboratory of animal husbandry of the State Institution “Institute of Grain Crops of NAAS of Ukraine”. The work was performed in accordance with the research program № 31 “Genetic improvement of farm animals, their reproduction and conservation of biodiversity (Genetics, conservation, and reproduction of bioresources in animal husbandry)”, task – 31.02.01.18. pigs of different genotypes and to develop an integrated system for creating a highly productive population” (№ DR 0121U107903). Evaluation of sows on the indicators of long-term adaptation and reproductive qualities was carried out taking into account the following characteristics: life expectancy, months; duration of breeding use, months; farrowing was obtained; received piglets total, ch.; obtained live piglets, ch.; multiplicity, ch.; nest weight at the time of weaning at the age of 28 days, kg; safety of piglets before weaning, %. The index “level of adaptation” was calculated according to the method of Smirnov (2003), the index of reproductive qualities – according to the method of M. D. Berezovsky. Economic efficiency of research results and biometric processing of the obtained data were carried out according to generally accepted methods. It is established that sows of large white breeds of the controlled herd are characterized by rather high indicators of reproductive qualities and level of adaptation to conditions of intensive technology of operation. The life expectancy of sows in the main herd is 44.1 months, the duration of breeding use – 32.8 months, the index “level of adaptation” – 11.87 points. According to the indicators of fertility and nest weight at the time of weaning, the animals of the main herd belong to the first class and the elite class. Taking into account intra-breed differentiation according to the index “level of adaptation” sows of class M- significantly outperformed peers of class M+ in life expectancy by 54.77 %, duration of breeding use – by 71.48 %, index “level of adaptation” – by 66.09 %. Significant differences between groups of animals of these classes were found by multiplicity (td = 2.22; P < 0.05), nest weight at the time of weaning at the age of 28 days, kg (td = 2.56; P < 0.01) and index MD Berezovsky (td = 2.60; P < 0.01). The coefficients of pair correlation between traits that characterize the level of adaptation and reproductive qualities of sows range from -0.704 (tr = 10.80) to +0.982 (tr = 213.05). The use of sow class M- according to the index “level of adaptation” provides an increase in additional products at the level of +5.71 %, or 140.80 UAH. We propose to select repair young stock from sows of the leading group with the index “level of adaptation” of 6.55–8.08 points in the conditions of breeding plants and breeders, as well as industrial complexes.

Calving Difficulty

The selection objective of the SAC Simmental MOET Project, is to improve the economic efficiency of lean, or saleable, meat production in crossbred beef production systems.The factors which contribute to the selection objective are the yield of saleable meat, feed intake and calving difficulty. These goal characteristics are combined into an index by taking into account their respective financial values and costs. Calves generated by multiple ovulation and embryo transfer (MOET) are weaned from their recipient dams at 10 weeks old and placed in performance test from 5 to 11 months of age. At the end of the performance test, saleable meat yield is estimated from liveweight at end of test, ultrasonic fat depth measurements and muscling score. Calving difficulty is predicted from the birthweight and gestation length of the animal on test whilst feed intake is measured directly by recording individual food intakes during performance testing. The estimated breeding value for the selection index of an animal is expressed in £'s (pounds sterling) as deviations from a mean of zero for the SAC population of Simmentals. It is calculated using the information for each animal plus that of all its relatives in its own and other performance tests by means of BLUP procedures.The objective of the work described here was to evaluate the effectiveness of the selection index in identifying sires of superior genetic merit for use in crossbred beef production systems.

ABSTRACTAn economic selection index was derived for terminal sire sheep breeds or strains, using physical and financial results from New Zealand export lamb-producing flocks. The aggregate breeding value of the index comprised carcass lean weight and carcass total fat weight. Index measurements were live weight, ultrasonic fat depth and ultrasonic muscle depth. Economic values used for lean and fat weights (NZ$5·65 and NZ$–1·2 per kg, respectively) were the change in profit per kg increase in lean or fat weight from that in the average carcass of lambs slaughtered in 1984/85. The s.d. of the aggregate breeding value was NZS3·20, and the correlation between the full index and the aggregate breeding value was 0·23. This correlation fell to 0·18, 0·15 and 0·07, respectively, when muscle depth or fat depth or muscle and fat depths were omitted from the index. Selection on the full index, or on the index omitting muscle depth was expected to lead to an increase in carcass lean weight and a slight decrease in carcass fat weight. Selection on the index omitting fat depth, or selection on live weight alone, was expected to lead to an increase in both fat and lean weights.

Relevance. Recently, the number of many breeds and lines of chickens has significantly decreased, while others are under threat of extinction. Reducing the genetic resources of chicken’s worldwide limits the possibilities of future breeding programs. The study of the genetic diversity of the species allows you to more accurately manage the productive and potential of chicken breeds, the possibilities of its use for obtaining Biosafety and full-fledged food. Adding exterior estimation data to the bird breeding value forecast increases its accuracy and is relevant.Methods. The study was conducted on chickens of two experimental populations «Experimental CS» meat-egg of productivity and «Experimental LZS» egg-meat productivity from the Genetic collection of rare and endangered chicken breeds Russian Research Institute of Farm Animal Genetics and Breeding — Branch of the L.K. Ernst Federal Science Center for Animal Husbandry.Results. The highest absolute increase in live weight of chickens is observed in the period of 4-8 weeks, and the relative increase at the age of 4 weeks, regardless of the type of productivity of chickens. The results of cultivation largely depend on the intensity of growth of the bird in the early period, up to four weeks of age. The superiority of the meat-egg population in comparison with the egg-meat population was revealed in terms of breast circumference (5.0–7.7%).

AbstractPuberty during performance test and the effect of reproductive maturity and performance on test on superovulatory response were investigated using Simmental heifers.Three generations of Simmental heifers (no. = 110) were performance tested for beef characteristics between 23 and 49 weeks of age over 3 years successively. Embryo recoveries were performed at 52 and 61 weeks of age following the end of the performance test. The onset of puberty was observed in 26 of 30 (87%) heifers in the 3rd year. The mean age at puberty was 284·7 (s.e. 6·63) days. Age at puberty was not significantly related to daily live-weight gain (1·5 (s.e. 0·02) kg) up to the onset of puberty. Heifers experienced zero to six oestrous cycles before initiation of the first superovulatory treatments. There was a non-significant tendency (P > 0·05) for heifers that were not cyclic to produce the highest yields of viable and grade 1 embryos at the first embryo recovery.Performance test characteristics recorded were: total food intake (1604·0 (s.e. 13·2) kg), total energy intake (1852·0 (s.e. 169·0) MJ metabolizable energy) and live-weight gain (263·9 (s.e. 2·2) kg) during test; live weight (486·5 (s.e. 31·5) kg), backfat depth (5·6 (s.e. 15) mm) and muscle score (9·6 (s.e. 0·10) units) at the end of test and estimated breeding value for the selection index (+£7·00 (s.e. 0·76)). These were used as independent variables in general linear models to study their relationship with various measures of superovulatory response. Recovery rate of ova and embryos; and the yields of viable and grade 1 embryos were not related to any aspects of performance on test.In conclusion, superovulation and embryo recovery were affected by reproductive maturity at the time of gonadotropin treatment and these procedures may be more effective in juvenile heifers before the establishment of cyclicity. Embryo production from 12- to 15-month-old Simmental heifers following a beef performance test was not related to their performance on test.

The results of research activities of reproductive qualities of sows of different breeding value are given, the level of their phenotypic consolidation is determined and the correlation analysis is carried out. The study was conducted in agricultural formations of Dnipropetrovsk and Sumy regions (LLC “AF “Renaissance”, research farm of the Institute of Agriculture of the Northeast NAAS of Ukraine, LLC “Druzhba – Kaznacheyivka”), livestock laboratory of the State Institution Institute of Grain Crops of NAAS of Ukraine and livestock laboratory economy of the North-East of NAAS of Ukraine. The work was performed according to the research program of NAAS of Ukraine № 30 “Innovative technologies of breeding, industrial and organic production of pig products” (“Pig breeding”). The object of the study were sows of large white breed. Indicators of reproductive qualities of animals of the specified production group were investigated taking into account the following quantitative signs: multiplicity, head; milk yield, kg, number of piglets at weaning, head; nest weight at the time of weaning at the age of 28 days, kg, safety, %. The BLUP index (maternal line) was calculated on the basis of the Main Breeding Center for Pig Breeding (Institute of Pig Breeding and AIP NAAS of Ukraine) according to the general model of a single animal. The index of alignment (homogeneity) of the sow's nest by live weight of piglets at the time of their birth, the index of reproductive qualities of the sow and the coefficients of phenotypic consolidation of the main quantitative traits were calculated according to the methods of V. I. Khalak (2012), M. D. Berezovsky (quoted from A. Vashchenko, 2019) and Yu. P. Polupan (1996, 2005), respectively. Biometric processing of research results was performed according to the methods of G. F. Lakin (1990). It was found that the maximum indicators of fertility, milk yield, number of piglets and nest weight at the time of weaning at the age of 28 days are characterized by sows of group I, in which the index BLUP (maternal line) is 109.78–128.75, the index of reproductive qualities (CPI) – 101.43–161.72 points. The correlation coefficients between the characteristics of reproductive qualities and integrated indicators are reliable and range from + 0.648 ± 0.0492 (index BLUP (maternal line) × milk yield) to + 0.984 ± 0.0086 (index of reproductive qualities (IRQ) × nest weight per weaning time at the age of 28 days). A high level of phenotypic consolidation on the basis of reproductive qualities of sows was found in animals of group II by milk yield (K1 = 0.561, K2 = 0.499) and nest weight at the time of weaning at the age of 28 days (K1 = 0.521, K2 = 0.472), peers of group I – by multiplicity (K1 = 0.315, K2 = 0.410) and the number of piglets at weaning (K1 = 0.296, K2 = 0.397). The calculation of economic efficiency of sows of different breeding value shows that the maximum increase in additional products was obtained from sows of group I, in which the index BLUP (maternal line) is 109.78–128.75, the index of reproductive qualities (IRQ) – 101.43–161, 72 points – +13.08 %, and its value is +332.08 UAH/head. These indicators of evaluation indices are a criterion for selecting high-yielding sows of large white breeds of controlled herds.

A study to find additional reserves for expanding the breeding beef cattle base and improving methods for selecting parental pairswas carried out. The issues of technical approachwere considered to substantiate the milkingabilityaccording to the herd. It characterizes the development of calves in the suckling period and significantlydetermines the weaning weight and the possibility of selection according to this basis. The method for selection of sires of Hereford and Aberdeen-Angus breeds with forecasting of breeding value of the selected trait in the reproduced progeny is presented. The index (IBS index of bull selection) was calculatedaccording to the phenotypic characteristics of the sire's selected traitbyweaning live weight of at least 40 its offsprings (20 bulls + 20 heifers) and average milking yield of the breeding stock, their deviations in herd and from the indicator of the desired type. Studying the breeding qualities of the Hereford and Aberdeen Angus bulls made it possible to draw a conclusion about the expediency of obtaining animals in the studied herds from the sires with a selection index of not less than 106% and 105 depending on their breed and the level of productivity of the breeding stock.

The aim of the study is to develop an effective selective index adapted to the conditions of the country, taking into account the national priorities of consumption of livestock products. Selection indices, which are widely used in de-veloped countries with high scientific and production potential in the field of animal husbandry, have been ana-lyzed. They can be divided into three groups. The first group includes five countries where a simplified version of the calculation of selective indices is used. The second group includes nine countries, which are rather complex for on-line analysis of the selection indices. The third group included countries in the breeding work of which com-bined breeding indices are used. The rating of the most valuable bulls of the Federal state unitary enterprise «Mos-kovskoye» on breeding work made with application of the most widespread selection indexes is given. Selection indices, with the similarity of the methods of their calculation, need some adjustment to be used in our country. A selection index is developed and presented under the name UI (combined index). The developed index UI in 83% of cases coincides with the index ASI (Australia), in the remaining 17% of cases the difference does not exceed 0.5 rank. With the index PIN (England) differences are more significant, in 34% of cases there is a complete coinci-dence of estimates, in 50% – the differences are only 1 rank and only in one case the discrepancy is significant enough. The index of INET (the most frequently used by breeders in Europe) coincides with the evaluation of breeding value of animals in 100% of cases. The new index is supposed to be used in the work with dairy breeds.
