REPRODUCTIVE INDICATORS OF SWINE AND ECOLOGICAL MEANS IN SOME PATHOLOGIES
With an increase in the world's population, the demand for environmentally friendly food is increasing. In this regard, the main task of animal husbandry is to intensify the reproduction of the herd and the maximum possible increase in animal productivity.
In this sector of agriculture, as in any industry, there are also various problems. One of these problems is that sows' productivity still averages around 40–60% of their potential
This is due to the fact that modern industrial pig breeding technologies do not always take into account the physiological needs of the pig’s body, which leads to weakened immunity and an increase in the frequency of various pathologies. Therefore, to increase the overall resistance of the animal organism and prevent postpartum pathologies, various means are systematically used. The most commonly used drugs are etiotropic therapy. But almost all of them have certain disadvantages: toxic effects on the body, irritating effects on tissues, long-term effects and various side effects, antibiotic resistance.
Therefore, veterinary specialists seek to limit the frequency of use of antibiotics by replacing them with drugs that do not potentiate antibiotic resistance, have immunostimulating properties and contain environmentally friendly and inexpensive components.
Such environmentally friendly drugs are effective due to the fact that the micronutrients or extracts of medicinal plants contained in them have good antibacterial and bactericidal, and sometimes fungicidal, immunostimulating and antiviral properties.
The use of such drugs, either alone or in combination with certain methods and drugs (synestrol, carbocholine, pituitrin, proserin, vitamins, UHF, EHF, etc.) allows you to get environmentally friendly products from the animal almost immediately after the course of treatment .
The aim of our research was to study the effectiveness of new, environmentally friendly and easy-to-use agents used for the treatment of postpartum endometritis in sows and their effect on some parameters of sows productivity.
The studies were carried out during 2018 in the conditions of the complex of selection and hybridization of pigs “Moldsudingbrid”, the city of Orhei, Republic of Moldova.
From the number of farrowing sows, queens with a diagnosis of postpartum endometritis were selected. The selected uterus was divided into 3 groups: one control and two experimental.
In the control group, all sows were treated according to the scheme adopted by the farm: injections of Enrofloxacin 50 were used according to the instructions 1 ml/20 kg body weight, once a day, intramuscularly 3–5 days.
The animals of both experimental groups were injected once, in the upper third of the neck (behind the ear), a tissue preparation was injected at the rate of 1 ml/100 kg of body weight. Before use, the drug was diluted with a 0.5% solution of novocaine in a ratio of 1:1. At the same time, 100–150 ml of a preparation made on the basis of an extract from plant D and a chelate compound of iodine were intrauterine administered to sows of the first experimental group. Animals of the second experimental group were intrauterine injected with 100–150 ml of a preparation made on the basis of an extract from plant C and a chelate compound of iodine. The frequency of administration was 1 time per day for 3–5 days.
Studies have shown that the duration of therapy in the experimental groups was less than in the control group. In the first experimental group, the duration of therapy was 4.44 ± 0.358 days and in the second experimental group 4.22 ± 0.386 days. This is 1.39 and 1.61 days (23.84% and 27.65%, respectively) less than in the control group.
The inter-porous period in the experimental groups after therapy was less than in the control group. In the first experimental group, the period between farrowing was 164.33 ± 6.645 days and in the second experimental group 180.75 ± 9.12 days. This is 12.17 and 5.85 days less than in the control group, where this indicator was 2.57 days.
The interval from weaning of piglets to the fruitful insemination of sows (when they first came to the hunt) in the experimental groups decreased by 5.15 and 6.6 days and amounted to 17.25 ± 5.01 and 9 ± 3.36 days. In the control group, the interval between weaning and insemination of sows was 18.8 ± 4.93 days, which is 2 days less than before the studies.
It has been established: 1) the new, environmentally friendly products that we offer are effective in the treatment of postpartum endometritis in sows; 2) do not adversely affect sow productivity; 3) contribute to improved reproductive performance and are more effective than antibiotic.
The data obtained will improve and specify the appropriate preventive, therapeutic and diagnostic and other measures necessary to increase the reproductive potential of sows
