Weaning Piglets

The most important element of pork production technology is the reproduction of the herd. Among all the reproductive traits of sows, there is a special emphasis on the heavy litter or live weight of piglets at birth, which largely determines the growth rate of young animals in further age periods. The livability of piglets ultimately determines how many young pigs will come to fattening and how much pork will be obtained. Therefore, the study of the reproductive traits of pigs is relevant for the theory and practice of pig breeding. The researches have been carried out under the environments of the reproductor of an industrial pig breeding complex, where the infl uence of the duration of the days open period and lactation of sows (suckling period) on their heavy litter and livability of piglets has been studied. The most signifi cant increase in sow fertility has been found, depending on the length of the days open period, when only one heat was missed. In the group of sows when weaning piglets at the age of 18, 21 and 24 days and the duration of the days open period of 21–28 days, the heavy litter was 0,054–0,197 kg more than when using sows with the days open period of 1–7 days. When inseminating sows with the days open period of 45 days or more compared to the group of sows with the days open period of 21–28 days, the increase in their heavy litter has not been observed. For example, the average heavy litter in the group of sows with the days open period of 45 days or more was 0,06 kg less than in sows with the days open period of 21–28 days. On average the groups of sows during insemination in the second heat after weaning piglets have shown the increase in heavy litter and livability of piglets compared to the group of sows without missing the heat. Sows inseminated in the second heat with the days open period of 21–28 days increased by 0.106 kg (P < 0,001) compared to the group of sows without heat missing. The researches have shown the increase in the livability of piglets in the groups of sows with the days open period of 21–24 and 45 days by more than 0,7–2,2 %, compared with the group of sows with the days open period of 1–7 days.

In order to improve the livestock industry, and push up it to the world level making full use of the biological features of animals it is necessary to radically improve the system of breeding work with the species selection and the best combinations to obtain the fattening of young animals, in the implementation of this task special emphasis on the pig as the most precocious and technologically advanced livestock industry. The advantage of pork production is evidenced by the economic assessment of meat production of diff erent types of animals according to the level of individual costs for the nutrients of the product. It is no coincidence that the growth rate of pork production in the world in recent years exceeds the growth rate of beef and poultry. The purpose of the work was to assess the reproductive traits of crossbred sows obtained from various dreeding boars of Landrace breed (1st paternal breed) and mated with breeding boar of Duroc breed (2nd paternal breed) during three-breed industrial crossbreeding. The research has been carried out on the basis of LLC “Agrofi rma Ariant” in the Chelyabinsk region. It has been found that among the analyzed crossbreds the highest reproductive abilities were distinguished by sows obtained from the breeding boar No. 62143 their prolifi cacy was 13,5 heads live piglets, and the live weight of 1 piglet at birth was 1448,07 g, which exceeded the indicators of sows daughters of breeding boar No. 620001 by 1,4 piglets, and 17,9 g, respectively. Approximately the same number of female pigs has been obtained in both study groups. The number of young boars from sows of breeding boar No. 62143 was by 1,3 head more. Thus, in order to increase the profi tability of pork production in LLC “Agrofi rma Ariant” it is necessary to increase the volume of use of sperm of breeding boar No. 62143 of Landrace breed

The purpose of the work was a comprehensive evaluation of the productive and reproductive traits of sows of Yorkshire and Landrace breeds and their offspring under the conditions of a breeding enterprise in the Republic of Belarus. During the studies of reproductive traits, it has been revealed that the highest rate of prolificacy among the evaluated breeds was distinguished by Yorkshire sows 14,0 heads for farrowing. In terms of milk content, Landrace sows were 2,5 kg or 4,57 % higher than Yorkshire sows. In terms of weight and socket weight per piglet at weaning at the age of 28 days sows Landrace piglets surpassed herdmates Yorkshire breed in the weight of the litter by 6,8 %, and the weight of one pig by 0,9 %. It has been found by the results of the evaluation of fattening and meat qualities of purebred young pigs that the best parameters were different gilts of Landrace breeds, whose age achieve the live weight of 100 kg was 163,1 days, and average daily gain of live weight – 864,8 g, which was higher than in young pigs of Yorkshire breed by 1,8 day or 1,09 %, and 28,9 g or by 3,46 %. The young pigs of Landrace breed has been characterized by the best values of the area of the “eye of loin” – 73,8 cm² and the highest yield and amount of meat – 68,5 % and 24 kg, which was 11,4 cm² or 18,2 % and 0,4 kg or 3,5 abs.%, respectively, higher than the herdmates of Yorkshire breed. The results obtained indicate the possibility of using boars and sows of Landrace and Yorkshire breeds not only in breeding, but also in industrial pig breeding.

The purpose of the researches was to study the influence of different doses of smectic kizelgur and calf skim milk replacer in the recipes of compound feed for young pigs under the conditions of industrial pork production technology. The experimental part of the work has been performed under the conditions of the pig complex of LLC “BMPK” in the Karachevsky area in the Bryansk region. The research materials were compound feed for young pigs on fattening in the inclusion of different doses of smectic kizelgur. The infl uence of feeding compound feed with different doses of smectic kizelgur and calf skim milk replacer to young pigs on productivity, digestibility of nutrients and use of nitrogen, morphological and biochemical parameters of blood, fattening and meat traits of young pigs has been studied. Effective recipes for feeding compound feeds to young pigs prepared with the inclusion of different doses of smectic kizelgur and calf skim milk replacer have been identified. The data have been obtained from the first experiment of young pigs when them fed compound feed with different doses of smectic kizelgur; it has been followed that at the end of fattening the biggest live weight of gilts had in the 4th experimental group fed compound feed, which included 3 % smectic kizelgur. The influence of the additive on changes in live weight and daily gains when adding smectic kizelgur to compound feed in doses of 1,5 and 2,0 % was less, but the trend to increase these indicators over the period of fattening has remained. In the second experiment young pigs have been fed by compound feed, which included different doses of smectic kizelgur and calf skim milk replacer the average daily gain in live weight was higher in the 3rd experimental group, where they fed compound feed with the addition of 2,5 % smectic kizelgur and 2,5 % calf skim milk replacer by 2,2 %, than in the control group. The highest efficiency has been also obtained in the 3rd experimental group, where the monetary revenue has been received by 2160 rubles more in comparison with the control group of pigs.

ABSTRACTAn experiment was conducted to study the ability of the pig to recover from the effects of a period on a food deficient in crude protein (CP). Forty young pigs were given free and continuous access to foods with either 150 (L) or 252 (M) g CP per kg in period 1 of the experiment, from 6·3 kg to 13·4 and 12·3 kg live weight respectively. These live weights were expected to give equal lipid-free empty body weights. In period 2, four males and four females from each of the period 1 treatments were given access to either M or a food with 377 g CP per kg (H) to a live weight of 30 kg, when the 32 pigs were killed.Pigs on L took 11 (s.e. 0·6) days longer to complete period 1, and had, at the end of this period, 0·20 (s.e. 0·03) kg less protein and 1·20 (s.e. 0·06) kg more lipid in their bodies than the M pigs, at a common ash weight. In period 2, pigs from L grew at a faster rate (750v.633 (s.e.d. 20) g/day), ate food at the same rate (1115v.1085 (s.e.d. 35) g/day) and converted food more efficiently (0·676v.0·585 (s.e.d. 0·016) g gain per g food) than those from M. At 30·3 kg live weight the pigs from L had corrected their protein deficit relative to ash and reduced their fatness, so that they had the same protein: ash ratio and only 0·47 (s.e. 0·12) kg more lipid in their bodies than those from M. This was the result of a higher rate of gain of protein and water, a lower rate of lipid gain and similar rate of ash gain by the pigs from L than those from M. In the first 7 days of period 2 the pigs from L gained weight at 1·4 times the rate of those from M. In the final 7 days there was no significant effect of period 1 treatment on growth rate. The pigs from L given food H in period 2 were more efficient than those given M in period 2 (food conversion efficiency (FCE) values of 0·884 and 0·791 respectively; s.e.d. 0·027), but this difference was reversed in the final 7 days (FCE values of 0·521 and 0·603 respectively). t I is concluded from these results that a period of eating a food of low protein content produces a reduced protein: ash and an increased lipid: ash ratio in the body and reduced growth rate and efficiency. When subsequently pigs are given a food of sufficiently high protein content, the protein: ash and lipid: ash ratios return to normal. The repletion of labile protein reserves, with their associated water, leads to a substantial increase in the rate of live-weight gain. The lower lipid content of the gain leads to a high efficiency. The duration of these effects depends on the protein content of the food given.

Abstract Sow milk is usually enough to meet the need for nutrients of three weeks age piglets. However from the beginning of life they need supplemental nutrients in the form of creep feeding. The objective of this study was to survey the usefulness of special mixed feeds (super starter, pre-starter, starter feeds) given as creep feeding and feeding to suckling pigs, as well as the use of immunostimulant for their health, better growth and development. The study showed that suckling pig fed with special super starter, pre-starter and starter mixed feed depending on age, as well as young animals additionally treated with intramuscular injected immunostimulant better by growth rate. The highest indicators for the live weight of piglets at the age of 60 days (weaning) and for the milk content of sows were in the experimental group, which was intramuscularly injected with an immunostimulator The highest live weight of (weaning) piglets aged 60 days was in treated groups.

The results of research on the use of the probiotic drug “Profort” in the diet of young pigs have been presented in the article. The research was carried out under the conditions of LLC “Agrofirma Ariant” on the crossbreds of young pigs. The purpose of the research was to study the eff ectiveness of the effect of the probiotic drug “Profort” in intensive pig rearing on the reproductive traits of sows and the productive traits of piglets. In order to conduct the scientific and economic experiment at the first stage, 2 groups of pregnant sows were formed in each with 10 heads. The feeding and housing of the experimental animals were the same. In addition to the main diet the sows of the experimental group were fed the probiotic additive “Profort” at the dose of 500 g/t of feed for 30 days before and 30 days after farrowing. At the second stage the resulting young animals were divided into 3 groups. In addition to the main diet the young animals of the 1st experimental group have been received the probiotic drug “Profort” from 7 to 105 days together with compound feed. Piglets of the 2nd experimental group have been received the probiotic additive from 7 to 30 days. It has been found during of studies that as a result of the use of probiotic additive the prolificacy of sows in the experimental group was higher – 10,6 compared to 10,4 heads in the control group. The livability of piglets for weaning in the experimental group was 97,9 % compared to 93,9 % in the control group. The absolute gain in live weight of piglets from 30 to 105 days in the experimental groups was 34,94–36,98 kg, which was higher than in the control group by 7,9–14,2 %. In the blood of piglets of the experimental groups, the increase in the level of red blood cells, total protein, calcium and phosphorus has been noted.

Currently, the existing literature sources on the use of feed additives “Tetra+” and “Glimalask” do not fully reflect the data on the comparative study of their infl uence on the physiological state, meat productivity and pork quality of fattened young pigs. Under the conditions of the Lower Volga region comprehensive researches were carried out in a comparative aspect to improve meat productivity and pork quality through the use of feed additives “Tetra+” and “Glimalask” in the diets of young pigs on fattening. The purpose of the work was to increase the productive and pork quality of young pigs on fattening due to the use of feed additives “Tetra+” and “Glimalask” in their diets. The research was carried out in the period from 2012 to 2019. The experimental part of the work took place under the conditions of the stud farm named after Lenin in the Surovikinsky district in the Volgograd region. The object of research was young pigs of Large White breed. The positive influence of feed additives on the digestibility and use of nutrients in diets, meat productivity and pork quality, physiological indicators and economic effectiveness of pork production has been proven. It has been found that the level of profi tability of pork production was higher in the experimental groups in comparison with the control group by 5,03 and 4,48 %, respectively. At the same time the highest effectiveness has been obtained from the animals of the 1st experimental group, which received the feed additive “Tetra+” in the diet, which allowed to increase the live weight gain by 6,74 %, the level of profitability by 5,03 %. Thus, the feed additive “Tetra+” was the most effective.

Ethologists have identified many aspects of animal behaviour, and their research experience can be used in agricultural production for the selection of animals with necessary behavioural qualities. The purpose of the study was to find labour saving and effective methods for the selection of young pigs for herd replacement, including identification of their behavioural characteristics in the context of industrial pork production. The method for the selection of young animals based on the viability index of newborn piglets was compared with other method, which takes into account the independent attachment of piglets to the front three pairs of sow teats. It was found that the probability of independent attachment of a piglet to anterior teats has a positive and high correlation with its viability index, with a correlation coefficient of 0.95. Piglets that occupied the front three pairs of teats during the suckling period significantly (P≤0.001) exceeded the rest in weight at the 21st and at the 60th days by 22.7% and 5.4%, respectively. When assessing the behavioural reactions of piglets weaned from sows in an artificially created stress conditions, groups of piglets resistant and not resistant to psychological (emotional) stress were selected for subsequent observation. Moreover, it was found that among the sows obtained from stress-resistant piglets, the superiority in fertility during the first insemination and the total proportion of farrowing was 11.1 p.p., in terms of multiple fertility – 2.6 piglets (P≤0.05) or 33.3%, and in terms of the share of those transferred to the main herd – 27.8 p.p. in comparison with the group of unstable ones. Based on the obtained results, the use of an ethological method for selecting piglets for herd replacement was substantiated, taking into account the independent attachment to anterior teats and an express method for selecting piglets based on their resistance to psychological stress

The improvement of production indicators (feed conversion ratio, average daily body weight gain, growth rate, etc.) in animal husbandry implies a high energy requirement. Such a need can only be met by including fats in the diet. Fat is the main and most efficient source of feed energy, but at the same time, one of the most expensive feed component. Using a fat emulsifier is an increase in the quality of the obtained product and a decrease in its cost. The addition of synthetic emulsifiers is a relatively new opportunity to increase fats’ active surface compared to other widely used feed additives. This reduces the cost for oil in the feed and also a chance to reduce feed total cost. By increasing fats’ active surface, emulsifiers expand the action of lipases and promote micelles formation. Higher the fat percentage in the diet, lower the percentage of its absorption. In high-energy diets without the use of complex emulsifiers, from 36% to 70% of the fat introduced into the feed is not absorbed and is excreted from the body. The beneficial effect of emulsifiers is that the digestibility of fat decreases, and it grows with an increase in the fat level in the diet. An assessment of the effect of the «Natufactant» feed additive on the growth rates of young pigs has been carried out. The maintenance and feeding of pigs were carried out in accordance with the technology adopted on the farm. The nutritional value of the main diet that is used on the farm, as well as after the inclusion of the feed additive «Natufactant», were determined. To conduct research according to the principle of analogs were taking into account the breed, live weight, and general physiological state, two groups of animals of a large white pig breed were created, 25 animals in each, with a live weight of 28 kg. The first group served as a control, and in addition to the main diet, the multicomponent emulsifier «Natufactant» was administered to the piglets of the research group at a dose of 250 g/t of feed, which was given together with the feed once per day. It was found that high average daily gains were obtained from animals to which «Natufactant» was added at the rate of 250 g per 1 ton of compound feed from the first day of the experiment and for 60 days in a row. As a result of the production check, it was found that the introduction of a feed additive into the diet of young pigs made it possible to increase the gross increase in animals’ live weight in comparison with the control, by 10.7 centners with the same level of feeding. New influence aspects of the fat emulsifier usage on the pigs’ physiological state and productivity were disclosed. It has been proven that the inclusion of the «Natufactant» feed additive into the animals’ diet stimulates the digestion processes and assimilation of basic nutrients, improves their physiological state, and increases the average daily weight gain of pigs by 15.3%. The solution to the problem of fats’ digestibility is the creation of new emulsifiers by searching for new molecules and developing effective complexes that have a synergistic effect when one component enhances the work of another. In order to significantly increase the pigs’ productivity and thereby increase the production of pork, it is necessary to ensure sufficient and adequate feeding of animals, taking into account the standards of lipid nutrition. It will also help to improve product quality and reduce production costs.

The influence of probiotic «Monosporin» on the growth performance of piglets using feed rations  varying degrees of balance. Is defined nutrients of basic ratio which is used at the farm, and normalized by the inclusion of corn bran and premix «Tekro». It is shown that the use of the basic diet with probiotic live weight of piglets increased by 1.3% and the average daily weight gain of animals – by 1.7–2.3% over the control. By using normalized diet with probiotic preparations value of body weight and daily weight gain of young pigs increased by 13.2–18.7% and 19.4–39.2% respectively. Comparison of productivity indices of piglets who consumed diets normalized without probiotics and with probiotic, indicates a an increase of 3.0–6.5% and 7.5–11.7% in favor of the latter. Along with the increase of animal growth performance using normalized diets with probiotic preparation «Monosporin» costs of fodder units per 1 kg of gain is reduced by 25.3%. The results indicate that the effect of the use of probiotics is associated with the fact that increases the digestibility of feed, improving their digestibility, it activates the body's metabolism, stimulates the synthesis of amino acids, vitamins, enzymes and antibiotic substances that suppress pathogens and increase the overall resistance of the animal organism to viral diseases and various adverse (stressful) factors. In assessing the cost efficiency of using normalized ration with the addition of premix TM «Tekro» and probiotic «Monosporin» shows that in complex their application the best result is observed: the level of profitability of 47.7%, and the profit from the sale of 1 head – 185.09 UAH. While the profitability of pork production of using probiotic  together with the basic feed ration is 7,8%.
