Abstract

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.

Keywords: horses, Orlov’s trotter breed, genealogical structure, reproductive composition, selection, population.

Abstract

The article presents the results of the genealogical analysis of Ukrainian population of horses Orlov’s trotter breed. The total number of the breed at the time of the survey was 653 horses, including 267 mares. The largest number of horses is in Zaporozhsky stud № 86 (29.6 % mares).

Analysis of the genealogical structure of the breed's reproductive composition showed the advantage of stallions of three lines: Barchuk (branch of the Zapad) (28.1 %), Pilot (18.8 %), and Voin (15.6 %). The mother composition mainly refers to the lines of Barchuk (branch of the Zapad) (30.7 %), Pion (22.1 %), Pilot (15.7 %).

The breeding stock of the Dubrovsky stud is represented mainly by mares of the Pion line (41.2 %), the Zaporozhsky stud – Barchuk line (a branch of the Zapad) (29.1 %), Ispolnitielnyi (22.8 %), and Pion (20.3 %). In Limarevsky stud, the majority of mares belong to the lines of Barchuk (branch of the Zapapad) (35.5 %), Pilot, Pion (25.8% each). Lozovsky stud is equipped with mares mainly of the Barchuk line (branch of the Zapad) (38.2 %), Pilot (23.5 %) and Vietier (20.6 %). The largest breeding reproducer of the «Kamyshanskoe» is equipped mainly with mares of the Barchuk line (branch of the Zapad) (51.2 %), Pion (22.0 %) and Pilot (17.1 %).

Analysis of the genealogical lines of the Ukrainian part of the population of the Orlov’s trotting breed showed that the most numerous is the Barchuk line with a more developed branch of the Zapad, which includes 28.1 % of stallions and 30.7 % of mares. The breeding core of the line is concentrated in four studs for breeding Orlov’s trotting breed (basic farms), as well as in breeding reproducers and horse owners-individuals. The genealogical offshoot of the Zapad is represented by descendants of 9537 Benzol and 10173 Pozyv, in particular 9 stallions and 78 mares of reproductive age. The presence of repair young in genealogical lines suggests their further development. Most of the genealogical lines, except for the lines of Barchuk, Pilot and Voin, are under threat of extinction, as they are represented by three or less stallions and, without the allocation or acquisition of new producers, will lead to a narrowing of the genealogical structure of the breed, which will negatively affect the population as a whole.

Keywords: cows, heifers of different age, signs of sexual activity, time of the day.

Abstract

The article reveals the feasibility of organizing and conducting the selection of cows and heifers by sexual activity for artificial insemination day and night. Revealed for three months in females (n=717): in 600 signs of sexual activity in 0,70 %, 700-19,94 %; 800- 19,25 %; 900 – 9,21 %; from 1000-1200-14.78 %; from 1300-1400- 4.32 %; from 1500-1600-15.2 %; from 1700-1900 – 9,76 %; 2000-6,83 %. It was revealed that most animals had sexual activity in the morning (49.10 %).

In August, 213 heads were studied, of which the signs of sexual activity in 600 had 2.35 %; in 700-14.08 %; in 800 - 11.74 %; in 900 - 8.45; in 1000 decreased to 3.29 %, in 1400 - an increase to 11.74 %; in 1600 - 12.68 %; in 1800 - 13.15% and 2000 - 22.54 %. Round-the-clock monitoring revealed a state of libido, for a period of 0000-400 hours morning 25,00 %, 400-800 – 18,27 %, 800-1200 – 17,34 %, 1200-1600 – 20,19 %, 1600-2000 – 4,81 %, 2000-2400 - 14,42 %. Of the 104 cows identified in the hunt, 62.5 % showed sexual activity in the period from 2000 to 800, and only 37.5 % of cows in the hunt were detected during the working hours of the artificial insemination operator. Also, from 22 heifers, 40.9 % showed signs of sexual activity in the period from 2000 to 800, and 59.09 % showed signs of sexual activity during working hours. Therefore, given the acceleration of physiological processes in the warm season, there are prerequisites for reducing the efficiency of the operator.

In September (an hour later), it was revealed in females (n=270): in 700 - 18.89 %, in 800 - 21.85 %; before 900 there was a decrease to 1000 %; and by 1000 hours - a rapid increase to 27.04 %; by 1400, a decrease to 1.85 %; from 1600 to 2000 - 12.96, 7.04 and 0.37 %, respectively. In October, out of 234 animals in 700, 26.50 % of females showed signs of sexual activity, which is 7.60 more than in September and 12.42 % more than in August; in 800 - 23.08 %; in 900-8.97 %; in 1000, a slight increase to 11.11 % was observed, by 1400 - a decrease to 0.43 % (similar to the previous month); in 1600, 20.09 % were detected, in 1800 - 9.83 %.

So, during the daylight hours, cows and heifers show signs of sexual activity not evenly: the first wave of excitement begins with a sunrise and lasts 4-6 hours, the second begins at 1400-1600 and continues until sunset.

The data obtained indicate that it is advisable to identify cow’s sexual activity both during the day and at night. Such studies should be carried out depending on the time of year: the length of daylight and the temperature of the environment. The conducted research can serve as a basis for compiling the multiplicity of detection of cow’s sexual activity during the day and the mode of their detection libido during working shifts by artificial insemination operators, their assistants and other workers.

Abstract

The article reflects the results of the studies on the Central Asian Shepherd dog breed. The dog assessment data on the main measurements, body indices, and certain characteristics of reproduction in various housing systems are considered. The objects of the research were adult dogs of the Central Asian Shepherd breed born in 2012 - 2017, 51 heads were kept by amateurs in Kherson city.

It was established that only 39.22 % of the total number was kept under apartment conditions, while the owners preferred males - their specific weight was from 58.06 % to 75 % of the total number. The vast majority (87.50 %) of the dogs, regardless of the conditions of housing, were never used in reproduction. The intensity of the use of the female dogs was associated with the conditions of housing – under of the aviary housing, at least once in their life they received offspring of 46.15 % of female dogs, under apartment housing – only 16.67 %. The average number of healthy puppies in the offspring was 8.29 heads. The speed of realization of the puppies was influenced by their gender. At the age of 4 to 8 weeks, 63.79 % of the young animals were sold, of which 73.33 % were males and only 53.57 % were females.

Regardless of the system of dog housing, pronounced sexual dimorphism was observed by the measurements (3.98 - 8.78 cm). Relative to the minimum size, the female dogs had an advantage at the level of 11.86 %, males - at 10.46 %. Thus, the female dogs were relatively larger than the males. The apartment housing did not affect the size of the dogs negatively. For most measurements, the advantage of the apartment kept dogs ranged from 2.09 to 5.54 %.

The live weight variability was greater than the measurements (variation coefficients ranged between 6.82 - 10.21 %), sexual dimorphism was quite pronounced – the males were 5.98 - 6.21 % heavier than the female dogs. As in the measurements, the female dogs had higher rates exceeding the minimum requirements for standard live weight than the males (31.75 % and 17.59 %). The apartment kept dogs had an advantage in live weight compared to the aviary kept dogs from 4.70 % to 5.73 %.

All dogs under study had a moderately stretched format, the value of the format index ranged from 102.67 to 106.44 units with the severity of sexual dimorphism at the level of 1.58 - 1.91 %. The aviary kept dogs had a longer format, the excess was from 1.74 % (female dogs) to 2.08 % (males), they had a lower density index than the dogs of the apartment housing (difference of 3.09 - 3.39 %). According to the mass index, there were no significant differences between the dogs, which were kept by the compared systems.

Abstract

It is known that pig farming is a traditional agricultural industry in Ukraine, which has a great potential. The main technological process at pig farms is the process of preparing and distributing animal feed. The success of the entire production depends on the perfection of these processes. Zoo-hygienic parameters of livestock buildings (speed, temperature and relative humidity, the level of harmful gases – ammonia and carbon dioxide, illumination) are important for ensuring the health and development of pig productivity. The influence of technological and design features of the preparation and distribution of feed in groups on the basic parameters of the microclimate in group stalls for pigs that will improve animal welfare. As these features, a technological line was developed, which made it possible to supply feed simultaneously to all three machines of the experimental group, in one working stroke. Wet feed into the buckets of the feed line was loaded based on its delivery in one pass of the distributor. Studies showed that 30 days after the start of the production test, the average air temperature in the pigsty was +24,13 °C and was the same for piglets of all experimental groups. The relative humidity in the machine where the control group № 1 was located was 1,3 % higher for the humidity in the machine tool of animals in the control group № 2 and   4,0 % higher than in the experimental group (these groups consumed wet food). 60 days after the start of the test, the air temperature was +22,07 °C for all experimental groups of animals. The relative humidity in the machine where the control group № 1 was (consumed dry food) was 4,0 % and 1,5 % higher than the same indicators in the animals of the experimental and control group № 2 (fed with wet food). The concentration of ammonia, carbon dioxide and air velocity in the machines for all experimental groups of animals was approximately the same and did not go beyond the permissible zoohygienic standards. The use of technology to ensure piglets receiving food and water from the developed facilities for the preparation and distribution of wet feed different consistency, compared with the control group № 1 and № 2, led to a decrease in the relative humidity in group stalls experimental group 4,0 % and 2,5 %, respectively.

Keywords: marker selection, polymorphisms, RYR1, CTSF, CTSD, Ukrainian Meaty pig breed.

Abstract

Effective selection in pig breeding is not possible without involvement of new approaches which involve the assessment animal genotypes at the DNA level. The development of methods for determining the polymorphisms in candidate genes that are responsible for the manifestation of economic traits is the basis of modern marker selection technology (MAS). Currently, a number of DNA markers have been developed for use in the breeding of farm animals. In this case, the most informative were single nucleotide polymorphisms (SNPs) of genes. However, despite the significant amount of scientific research, the problem of development and implementation of DNA markers for breeds of Ukrainian selection remains relevant.

The results of SNPs study of RYR1, CTSF and CTSD genes by PCR-RFLP method are presented. The initial stage for implementing marker selection for single nucleotide polymorphisms is conducting genetic-population analysis in the studied population of Ukrainian Meaty pig breed. It was found that SNP RYR1 g. 1843 C>T was characterized by low polymorphism, the minor allele g. 1843 T met with a frequency of q = 0.05. SNP CTSD g. 70 G>A had a low level of representativeness, allele g. 70 A prevailed at a frequency of q = 0.92. It was found that SNP CTSF g. 22 G>C was characterized by a sufficient level of representativeness, both alleles were detected with a predominance of the allele frequency g. 22 G (q=0.80).

In the population of Ukrainian Meaty pig breed, there was a statistically confirmed deviation of genotype frequencies from SNP-balanced CTSF g. 22 G> C (χ2 = 28.125) and CTSD g. 70 G> A (χ2 = 26,518). In the future, SNPs of CTSF, CTSD genes can be used for associative studies to find a link between markers and signs of pig productivity and the introduction of marker-associated selection in the UM pig breed.

Keywords: rams, breeding value, quality of descendants, estimation methods, growth rate, preservation, newness factor.

Abstract

The results of evaluating the breeding value of rams of different genotypes by a wide range of productivity indicators of their descendants are presented. Tribal rams of the Kharkov interbreed type of Prekos breed of 2-3 years of age, as well as crosses from the introductory crossing of Prekos sheep with the Romanov breed and Merinolandsheep, were evaluated. The resulting offspring were grown under the conditions of one production flock. The evaluation considered the indicators of the reproductive ability of ewes, sex and type of birth of the offspring, the safety of lambs from birth to 20 days of age, the dynamics of the average daily growth of daughters in the uterus and at the age of birth to 20 days and from 21 to 90 days, live weight indicators were considered, cutting and length of hair of daughters at the age of 14 months.

Studies have established that the average yield of lambs throughout the sample was 115.3 % per 100 ewes, with significant differences between the estimated producers - from 105.1 to 131.3 %. This indicator did not have a definite relationship with the genotype of the estimated sheep.

Among the offspring of all rams, males slightly prevail over females in the ratio of 1.09 to 1. This advantage is due to the large number of rams born among same-sex twins. Their part exceeded 28 %, while only 23.4 % turned out to be similar in type of birth.

By the sum of the ranks that were put to individual sheep for the indicators of the average daily growth of daughters at different periods of their growth, the best cross-breed sheep No. 1625 and No. 9953 are distinguished. On the whole, there is a fairly clear tendency for a positive relationship between the ranks for the growth rate in the embryonic period and the same indicator for posterity aged 21-90 days.

According to both the ranking and the probity-based evaluation results, ram No. 1625 (a created line based on crossing with the Romanov breed) is assigned to complex improvers. The rest topping ram out to be improvers of individual traits, and the producer of the breed Prekos No. 1823 was an improvement in production of wool and length of staple.  Ram No. 1960 turned out to be a complex deteriorator in the quality of offspring.

The descendants of rams No. 4464 and 9953, derived from the breed of Merino landscape, reliably (p≤0.01), by 18.6-20.8 % in terms of wool coefficients, are inferior to the daughters of ram No. 1823, breed Prekos, which is an unconditional evidence of the strengthening of their characters meat productivity over wool one.

Abstract

The aim of the article was to determine genetically and mathematically optimal target standards for pig selection for future generations. To determine minimal selection limits for pigs to obtain high productivity traits. We used common methods of evaluating the reproductive ability of sows, fattening and meat-fat qualities of progeny. Selection indexes were built by the method of standardized deviations according to M. V. Mykhailov. The target selection limits for animals were determined using the table of Le Roy. Selective-genetic parameters were determined by the main traits of reproductive ability, fattening and meat productivity of pigs. Selection indexes were estimated using the weighting coefficients of the traits for each group of pigs, used as a basis for minimal limits at different intensities of selection. The estimation of local progeny by selection indexes allowed ranging them depending on the level of productivity with the consideration of genotype. At 20 % selection, the minimal value of the reproductive ability index for the control group was 238.7 points. The minimal target threshold while selecting sires by the fattening traits of progeny within the 20 % selection was from 50.57 to 255.65 points for different groups. The minimal value of the index of fattening and meat traits was in the range from 270.05 to 606.94 points. The index estimation of pigs during the crossing allowed ranging them by the values of indexes. Minimal limits of selecting animals were determined and the selection of parental pairs with estimated productivity was optimized: in case of 20 % selection by multiple pregnancy with at least 11 animals, the area of loin eye – 30.5 – 44.5 sq.cm. It would be reasonable to select the animals, the productivity of progeny of which is above the determined limit, for further breeding from 238.70 to 606.94 points.
