“…Moreover, the reduction of abdominal fat weight [23] and fat content in broiler carcasses was observed [23,24]. The numerically lower fat content in skeletal muscles of fattening pigs supplemented with biochar was also confirmed by the authors in previously published studies [16]. In contrary, opposite results regarding fat content are reported by Chu et al [8] for longissimus dorsi of fattening pigs fed with the addition of bamboo charcoal.…”

“…Previously, authors examined the effect of three natural sorbents in the diet of fattening pigs on two skeletal muscles and demonstrated that the sorbents have no negative effect on the physicochemical properties of meat and use it as case-ready meat or processing material [16]. To the best of our knowledge, to date, no other studies have described the effect of the addition of natural sorbents to feed on the fatty acid content of pig meat and fat.…”

The fatty acid composition of meat and fat was studied in Choice Genetics line pigs fed a diet with three natural sorbents. Control (C1 and C2), biochar (D, 0.5%), bentonite–montmorillonite (A, 1.5%) and zeolite–clinoptilolite (B, 1.5%) diets were used in two trials. The samples of back fat, kidney fat and Longissimus lumborum (MLL) and Semimembranosus (MSM) muscle were examined. All sorbents (D, A and B) had no effect on fatty acid composition in MLL, whereas in MSM turned out to be very limited and inconsistent. Although A and B sorbents had a significant impact on the fatty acid profile of kidney fat, their effect was often opposite. Sorbent B’s effects were less beneficial due to a significantly higher proportion of saturated fatty acids, higher value of thrombogenic and atherogenic indexes, n-6/n-3 ratio but lower h/H ratio. Sorbent A’s effects significantly increased polyunsaturated fatty acids, and positively influenced lipid health quality indices. In summary, the feeding of natural sorbents slightly modified the fatty acid profile of muscle tissue, kidney fat and back fat; however, it did not have a negative effect on the indices of nutritional and pro-health quality of adipose tissue of pigs during fattening.

Background The study assessed the effect of smectites (bentonite and zeolite) used as natural sorbents in the diet of pigs on feed digestibility, health parameters, the severity of anatomo-histological changes in organs, and the accumulation of volatile pollutants in organs. Material and methods The study was conducted using fattening pigs (crossbreds from multiple breeds) assigned to three groups – a control (C) and two experimental groups (A and B), with 240 pigs in each group (3 replicates × 80). The animals in group C received a standard complete diet, while groups A and B received diets with 1.5% composed smectite sorbents. The feed and faeces were analysed for content of dry matter, crude ash, crude protein, ether extract, and crude fibre. The content of P was determined using a Helios Alpha UV–VIS spectrophotometer. Whole blood was analysed for haematological parameters and serum for biochemical parameters. Tissue samples were collected for analysis of volatile substances and histological analysis. After slaughter, samples of the lungs, liver, kidneys and jejunum were collected for morphological evaluation, and samples of the perirenal fat, liver, kidneys, lungs and brain for headspace gas chromatography (GC) to determine the levels of volatile toxic substances. Results A statistical increase in the digestibility of crude fibre and an increase in that of P were observed in both experimental groups (A and B) in comparison to the control. The whole blood and serum of the pigs from the control group had statistically significantly higher levels of creatinine, urea, and Mg and a higher WBC count compared to both experimental groups (A and B). Conclusions The feed additives were not shown to have a negative effect on the health parameters analysed or on accumulation of pollutants in selected tissues. No significant effect on the digestibility of most nutrients was observed; only an increase in the digestibility of crude fibre and a decrease in P digestibility were noted in the experimental groups.

Compliance with feed safety in livestock production requires pork producers to add mycotoxin-binding adsorbents to pig diets. Therefore, the purpose of the study was to evaluate the effect of two complex sorbents added to the diet of fattening pigs on their performance. The experiment included 90 pigs, which were kept in LLC “Tavriyski svyni” in the Kherson region. According to the principle of analogues, experimental animals were divided into three groups of 30 animals each: I – the control group of pigs consumed the basic diet “Grower”, and “Finisher”; pigs of experimental group II consumed the basic diet “Grower”, “Finisher” with the addition of 0.15% by weight of feed of a commercial analogue of mycotoxin adsorbent; animals of experimental group III received the basic diet “Grower”, “Finisher” with the addition of 0.15% by weight of feed of the complex preparation “Hepasorbex”. Animals that consumed feed containing adsorbents of mycotoxins had a higher live body weight, and average daily weight gain, reaching weights of 100 and 120 kg with lower feed conversion earlier compared to analogues of a control group. It was found that the introduction of “Gepasorbex” in the diet of store pigs of experimental group III at a pre-slaughter weight of 100 and 120 kg resulted in an increase in: slaughter yield, half-carcass length, muscle eye area, the weight of the hind third of the half-carcass and a decrease in the thickness of the fat compared to the control group. In terms of chemical composition, the meat of animals of experimental groups, both at slaughter in 100 kg and in 120 kg, met the requirements for pork of normal quality (NORMAL). At a live weight of 100 and 120 kg, pigs of experimental group III had significantly lower moisture content, higher protein, fat and ash content in meat. Due to the complex composition of “Gepasorbex” ingredients, the nutrients in the feed remained and were absorbed by the pig’s body, which is confirmed by higher productivity indicators and significantly reduces the cost of the main expense item of pig farms in pig production technologies – “Feed”. Therefore, this research is useful for specialists in pork production and processing in developing strategies for feeding pigs and obtaining quality raw materials for processing enterprises, which opens up ways to ensure food security in the country
