“…On the other hand, it is known that obesity of pigs leads to metabolic disease in late pregnant sows and has been linked to decreased litter weight, constipation at farrowing, and detrimental impacts on the intestinal health of developing piglets (Cheng et al, 2020;Peltoniemi et al, 2023). However, according to other scientists (Prunier & Quesnel, 2000;Waller et al, 2006) a positive energy balance, together with excellent body condition and a high body condition score, are thought to be advantageous for proper cyclicity and fertility in a number of species, including pigs.…”

Since the efficiency of pig breeding largely depends on the reproductive ability of sows, one of the promising areas of research in animal husbandry is the study of factors whose correction can improve the fertility and quality of the offspring. Our work purpose was to investigate the effect of gilts’ feeding level, MC4R genotype and interaction of these factors on the reproductive traits pigs after reaching puberty. The object of the study was crossbred pigs obtained as a result of the combination of sows of the Large White breed with boars of the Landrace breed. To carry out the research, the animals were divided into four groups that differed among themselves by the genotype of the melanocortin 4 receptor gene and the level of feeding of the experimental animals. To determine the genotype, the PCR-RFLP method was utilized. Genetic studies were conducted in a certified laboratory of the Institute of Pig Breeding and Agroindustrial Production. The reproductive capacity of the pigs was determined after receiving the farrowing by the following traits: piglets born alive per farrowing (animals), weight of litters of piglets at birth (kg), average weight of piglet at birth (kg), number of weaning piglets (animals), weight of litters of piglets at 28 days (kg), average weight of piglet at 28 days (kg), average daily gain of suckling piglets from 0 to 28 days (g). It was established that the traits of reproductive ability of crossbred Large White × Landrace pigs were affected by the interaction of genotype and feeding factors. When limiting the nutritional value of the daily diet, sows with the AG genotype outperformed those with the GG genotype by 1.2 piglets born alive per farrowing, by 3.0 kg for litter weight at birth, and by 0.1 kg for the average weight of a piglet at birth. The advantage of the AG genotype for average piglet weight at 28 days was even larger. Conversely, in conditions of a high level of feeding, animals with the GG genotype had higher productivity in terms of such traits as piglets born alive per farrowing – by 1.6 animals; weight of litters of piglets at birth – by 4.1 kg; for average weight of piglet at birth – 0.2 kg; by number of weaning piglets – 2.0 animals; by weight of litters of piglets at 28 days – 28.8 kg; for average weight of piglet at 28 days – 1.1 kg and for average daily gain from 0 to 28 days – 34.6 g. In the future, the goal is to develop a system of differentiated rationing of pigs' diets depending on their genotype.

“…The studies mentioned above were conducted based on the genetic perspective. In addition, diseases [10], feeding management [11], the order of parity [12], metabolite analysis [13], gut microbiota [14], and endocrine-disrupting chemicals (EDCs) [15] can all affect pig LS.…”

Although sows do not directly enter the market, they play an important role in piglet breeding on farms. They consume large amounts of feed, resulting in a significant environmental burden. Pig farms can increase their income and reduce environmental pollution by increasing the litter size (LS) of swine. PCR-RFLP/SSCP and GWAS are common methods to evaluate single-nucleotide polymorphisms (SNPs) in candidate genes. We conducted a systematic meta-analysis of the effect of SNPs on pig LS. We collected and analysed data published over the past 30 years using traditional and network meta-analyses. Trial sequential analysis (TSA) was used to analyse population data. Gene set enrichment analysis and protein–protein interaction network analysis were used to analyse the GWAS dataset. The results showed that the candidate genes were positively correlated with LS, and defects in PCR-RFLP/SSCP affected the reliability of candidate gene results. However, the genotypes with high and low LSs did not have a significant advantage. Current breeding and management practices for sows should consider increasing the LS while reducing lactation length and minimizing the sows’ non-pregnancy period as much as possible.
