Subjects of research: The group of karakul sheep fed in a various energetic caloric.
The aim and function of investigation: In the condition of new economical trends to work out the effective technological system relying on gaining weight of male lambs separated from ewes in the same year, keeping them, intensifying system of feeding in order to decrease the capacity of lambs in meadows and as a result of which relating on getting products.
The methods of investigation: zoo-tcchnical and biological
Achieved results and their novelty: The high level of rapid growth and fleshiness of karakul lambs is specified with clearly outlines that beginning from 2-2,5 months to feed them with extra food based on a high energetic ration. The weight of 4-4,5 monthly lambs reach 30,5±0,26 kg. The lactation of experimental ewes is higher than the controlled ewes of the I group for 22,6 %, the II group for 23,2 %. Making up 13,3 kg of experimental group lambs’ body (I group) and 14,8 kg (II group) and 47,3 and 47,9 % getting meat, 2,25 and 2,73 % of fat collection shows the highness of meat industry than usual demands and the high efficiency of gaining weight of young karakul lambs. According to the diet-II the morphological constituents of the body’s of the II group extra fed group lambs showed that the inter-balance between the amount of flesh and bones (fleshiness coefficient) should be 0,29 units comparing to the I group lambs, 1,08 units comparing to the controlled group-mates. Beginning supplementary feeding from the 2 period of ewes’ pregnancies will increase the living function of lambs, if there was not noticed any sheer losses, this indicator would make 2,5 - 3 % in animals kept in farm circumstances, comparing to the experimental group-mates ewes’ high birth of this group was lessened for 6,4 % .
Practical value: The practical value of the investigation was seen in the priority in the field of karakul sheep breeding to increase rapidly the male lambs which don’t satisfy the requirements of sheep market, to get a rational use from the energy of young organism, embedding little labour; pecuniary-technical means and finance to work out the technological system of increasing the productivity as well as profitability and efficiency of the system.
Application degree and economical efficiency: The result of investigation is utilized in karakul sheep breeding plant: “Karnab ota” of Pakhtachi region of Samarkand. The net profit received from one lamb of the II group makes 27151,8 sums while the lambs of the I and controlled group makes 19167,1; 10282,6 sums, profitability level constitutes correspondingly 54,1,42,1; and 25, 01 percents.

The fauna, distribution and ecology of filariata of the birds and mammals in Uzbekistan
The urgency and relevance of the theme of the dissertation.Filariata form a large and widely distributed group of parasitic nematodes that cause a series of very dangerous diseases in humans and animals, which arc called “filariases”. “According to the World Health Organisation (WHO), about 120 million people around the world living in the subtropical and tropical zones arc infected with filariases, with about 40 million being disabled persons, whose disability was caused by lymphatic filariases and lymphatic tumours”1.
Filariata cause a number of parasitic diseases in wild and domestic animals, such as parafilariasis, onchocercosis, setariosis, stephanofilariasis and dipctaloncmosis, and thus cause huge economic damage to cattle breeding and processing industries. This is why it is highly important to identify parasitic nematodes causing filariases, diagnose infected animals and develop preventive measures.
The necessity to develop filariases prevention methods for animals on the basis of the parasitic nematodes’ general biologic life cycles determine the huge practical importance of Filariata for health protection and veterinary science.
To modernize the taxonomy of the suborder Filariata on the basis of the contemporary characteristics of subspecies taxons, which remain debatable so far, is scientifically important for the theoretical parasitology.
Filariata parasitise vertebrates and cause highly dangerous diseases in them, which in the end impede the development of the main cattle breeding industries and their productivity. To develop methods to control filariases and to introduce them into the practical veterinary science arc among the topical tasks.
This thesis will help solve the tasks set in the decrees of the President of the Republic of Uzbekistan -PD-308 “On measures to stimulate the growth of livestock at private and state farms” issued on 23 March 2006 and PD-842 “On additional measures to stimulate the growth of livestock at private and state farms and to increase the amount of animal produce” issued on 21 April 2008, as well as in other normative legal acts concerning this area.
The aim of the research workis to identify the fauna, biology and life cycles of the most numerous species of parasites of birds and mammals - nematodes from the suborder Filariata, to modernize Filariata’s taxonomy and to prevent filariases in agricultural animals.
Scientific novelty of the research workis as follows:
the species diversity of Filariata of birds and animals was eastablishcd, with 53 species recorded in birds and 23 - in mammals;
46 of the 76 Filariata species were recorded for the first time for Uzbekistan, while the species Paronchocerca bumpae- for the Palacarctic;
the life cycles of predominating Filariata species (Aprocta cylindrica, Diplotriaena isabellina, Ornithofilaria falisensis, Onchocerca lienalis, Stephanofilaria stilesi and S. assamensis) were determined in the course of experiments;
the nucleotide sequence 5.8S+ITS-2+28S was determined to differentiate the species Setaria equina and Setaria labiatopapillosa;
changes were made in the taxonomy of the Filariata supcrspccics on the basis of a comparative analysis of Filariata’s morphology, biology and ecology, taking into account the belonging of certain groups of the nematodes to specific vertebrate hosts;
changes were made to the size and limits of the families Splcndidofilariidac, Diplotriacnidac and Oswaldofilariidae, in which Filariata parasitizing amphibians and reptiles were isolated into a separate group;
The separated species were included in the new families Icosiellidac and Oswaldofilariidae, which form the supcrfamilyOswaldofilarioidca supcrfam.nov;
Measures were developed to prevent filariases in agricultural animals.
CONCLUSION
The following conclusions were made from the results of the research carried out as part of the doctoral thesis “The faunam distribution and ecology of Filariata of birds and animals in Uzbekistan”.
1. 53 Filariata species were recorded in various ecological groups of birds. These species belong to 4 families and 22 genera; 46 of the 53 species were for the first time recorded in Uzbekistan, and 1 species (Paranchocerca bumpae) - for the first time in the Palacarctic.
2. 23 Filariata species belonging to 5 families and 9 genera were recorded in mammals; it was established that most of the species parasitise even-toed and oddtoed mammals.
3. The birds and mammals of the biogeocoenoses of Uzbekistan arc infected with 76 Filariata species, which comprises 13.0 % of the total of the world Filariata fauna.
4. It was established that Filariata recorded in birds and mammals can only parasitise in organs not connected with the external environment.
5. By their biological characteristics Filariata arc referred to heteroxenous forms; the class Insccta (Acrididae, Simuliidac, Culicidac, Muscidae) were identified as their intermediate hosts, and 14 bird orders and 7 mammal orders as their definitive hosts.
6. The life cycles of nematodes Aprocta cylindrica Linstow, 1833, Diplotriaena isabellina Koroliowa, 1926, Omithofilaria fallisensis Anderson, 1954, Onchocerca lienalis (Stiles, 1892), Stephanofilaria assamensis Pande, 1936, S.stilesi Chitwood, 1934 were established in the course of experiments.
7. A comparative analysis of fragments of nuclcotdc sequences 5.8S+ITS-2+28S was made to differentiate the species with similar morphlogics-Se/arm equina (Abildgaard, 1789) and Setaria labiatopapillosa (Alessandrini, 1848), and thus differences in the diagnoses of these nematodes were established.
8. Diagnostic characteristics were determined to differentiate Filariata in all the stages of their development (adult and larval stages and microfilariae).
9. Considerable changes were made in Filariata’s superspecies taxonomy. New size and limits were established for the families Splcndidofilariidac, Diplotriacnidac, Oswaldofilariidae and Lcmdanidac, and new taxons were suggested.
10. The composition of Filariata was justified. The suborder consists of 4 supcrfamilies(Filarioidca, Aproctoidea, Diplotriacnoidca and Oswaldofilarioidca), each of which is divided into groups of familiesincluding parasites specific to certain classes of vertebrates. The taxonomy of nematodes of the suborder Filariata was modernized.
11. It was established that filariases (parafilariasis, onchocercosis, setariasis, stephanofiariasis, dipctaloncmosis and dirofilariasis) was a common disease for animals at different types of farms; the infection rate depended on the season and geography. The extensiveness of the infection ranged between 4.8% and 75.7%.
12. Ivcrmcktin solution (1%), a broad-spectrum medicine, is recommended to cure animals infected with filariases; also, filariases prevention methods were developed.
