Dynamics of morphological and biochemical indicators of blood of young pigs using Globigen® Pig Doser and Globigen ® Jump Start with different methods of their keeping

The results of the production approval fully confirmed the high efficiency of introducing the feed additive “Butaselmevit-plus” into the compound feed for piglets. It was established that at the end of the piglet rearing period (at the age of 75 days), the average weight of one head in the experimental group was 32.6 kg, which is 1.1 kilograms or 3.5% higher (P < 0.05). Then their peers from the control group. During the period of rearing, the absolute increase in body weight in young animals of the experimental group was higher by 1.2 kg, or by 4.7 %, and the average daily weight gain by 21.8 g, or by 4.7 %, compared to similar indicators in piglets of the control group, and were 26.5 kg and 481.8 g, respectively. Among the numerous indicators determining the economic efficiency of production, the cost per unit of production is considered the most important. One of the reserves for reducing the cost of pig production is increasing young animals' productivity and preservation. The above results of the production inspection convincingly prove that using the feed additive “Butaselmevit-plus” in compound feed for piglets at the rate of 100 mg/kg of body weight increases their product qualities and, as a result, improves economic indicators. In the experimental group, the cost of 1 kg of live weight of piglets during rearing decreased by UAH 0.57, or 3.0 %, compared to the young of the control group and amounted to UAH 18.25. The cost of 1 kg of live weight gain in control and experimental groups was slightly higher (23.44 and 22.46 UAH, respectively), and the difference in favor of the latter was 4.2 %. The decrease in the unit cost of production in the experimental group was due to the increase in body weight and the survival of young pigs during the rearing period. The economic effect of using the feed additive “Butaselmevit-plus” as part of compound feed, calculated per 1 head of young pigs, was UAH 25.97 at the prices set for feed and feed additive in 2019. To increase the adaptability of piglets at an early age when weaning from the sow and to prevent the development of oxidative stress, for further maintenance during the period of rearing and fattening, it is recommended to use the feed additive “Butaselmevit-plus” in the amount of 100 mg/kg of body weight per day together with concentrates diet in the period from 21 to 40 days of age.

“…Галузь свинарства формується під впливом комплексу факторів, серед яких головна роль належить організації збалансованої повноцінної годівлі тварин (Skoromna et al, 2019;Martyshuk et al, 2021;. Поряд із забезпеченням енергією, протеїном та біологічно активними речовинами особливу роль відіграють мінеральні речовини, незважаючи на те, що вони необхідні тільки в невеликих кількостях, їхні функції в організмі не можуть бути компенсовані іншими компонентами (Voloshchuk et al, 2014;Ibatullin et al, 2014;Kozenko et al, 2022;Xiong et al, 2023).…”

The effect of feeding the drug “Kronocid-L” with the content of chelated compounds of trace elements on the productivity and slaughter performance of fattening pigs was studied. The scientific and economic experiment was conducted on two analogous groups of 75-day-old fattening young pigs, 12 heads in each, obtained from crossing sows of the large white breed with boars of the landrace breed. The experiment lasted 105 days and consisted of two periods: an equalization period (15 days) and a main period (90 days). The control group of pigs consumed the basic diet during the equalization and baseline periods. The compound feed “Grower” included: corn – 25 %, wheat – 25 %, barley – 23 %, sunflower meal – 12 %, wheat bran – 7 %, soybean meal – 3 %, BMVD – 5 %. “Finisher” compound feed included: barley – 38 %, wheat – 24 %, wheat bran – 12 %, corn – 9 %, sunflower meal – 9 %, BMVD – 4 %. In addition to the main diet, the experimental group was fed the drug “Kronocid-L” with the content of chelated compounds of microelements at the rate of 1 liter per 1 ton of water. The drug “Kronrocid-L” is a transparent green-blue solution that contains chelate compounds of trace elements (iron, zinc, manganese and copper), formic, acetic, orthophosphoric, lactic, citric, succinic and benzoic acids in an amount of 19 % by weight in an aqueous solution. Experimental animals that received the drug “Kronocid-L” during the first stage of the main period (75–110 days) and the second stage of the main period (111–165 days) outweighed the pigs of the control group by live weight by 5.9 and 7.4, respectively %, with an average daily increase of 9.5 % (P < 0.05) for the entire period of fattening. The use of the drug “Kronocid-L” at the rate of 1 liter per 1 ton of water allows to reduce feed consumption by 6.2 %, which is 3.0 kg per 1 kg of growth. At the end of the scientific and economic experiment, a control slaughter of experimental pigs was carried out, 4 heads from each group. It was established that feeding pigs on fattening with the above-mentioned preparation contributes to an increase in slaughter weight and slaughter yield in the 2nd experimental group, respectively, by 12,8 kg or by 15 % (P < 0.05) and 5.6 % (P < 0.05) against benchmarks. At the same time, under the influence of the feed additive, the thickness of the lard above the 6–7 thoracic vertebra decreased by 3.2 mm or by 10 % (P < 0.05) and the area of the “muscle eye” increased by 2.8 cm2 or 6 % P < 0.01).

“…Мінеральні речовини позитивно впливають на активність ферментів, гормонів, вітамінів, стабілізують кислотно-лужну рівновагу і осмотичний тиск. Вони впливають на функції кровотворення, ендокринних залоз, захисні реакції організму, мікрофлору травного тракту, беруть участь у біосинтезі білка, зміцнюють проникність клітинних мембран тощо (Hekkiiev, 1996;Kozenko et al, 2022).…”

Productivity of pigs under the conditions of introduction of the additive of the mixed ligand complex of Cuprum

Фарионик

2023

The intensification of the pig industry requires the breeding of highly productive young animals capable of providing high-growth energy under good conditions of maintenance and full feeding. Full feeding of suckling piglets in most farms of Ukraine is provided by pre-starter compound feeds of imported production, which leads to an increase in the cost price of pork. In addition, the traditional sources of trace elements in these compound feeds are mineral salts in the form of sulfate and chloride compounds, the bioavailability of which is 12–35 %, which leads to environmental pollution with heavy metals, and the crystallized water contained in sulfate molecules in the premixes destroys vitamins and other biologically active substances. The degree of assimilation of trace elements increases with the use of feed additives with trace elements of organic origin. Representatives of such feed additives are mixed ligand complexes of trace elements (chelates). Taking into account the fact that suckling piglets need Ferrum addition to mother's milk and a sufficient amount of Cuprum on the 4–5th day of life since Cuprum catalyzes the incorporation of Ferrum into the heme structure and is an indispensable activator of hemoglobin synthesis and a stimulator of erythrocyte maturation, the study of the action of this element in the composition of a mixed ligand of the complex in the pre-starter compound feed is relevant. In addition, the study of the economic and economic significance of the use of the mixed ligand complex of Cuprum in the feeding of suckling piglets, the establishment of optimal norms of this supplement taking into account the breed and parent age, has an important scientific and practical significance. The domestic and foreign experience of effective pig farming shows that the realization of the hereditary qualities of modern high-performance pig breeds and obtaining ecologically clean products is possible only under the condition of the development and implementation of perfect technologies for the production of pig farming products, which must be consistent with the biological needs of animals.
