Abstract Moderately low protein (MLP) diets can help decrease nutrient excretion from the swine production. However, MLP diets negatively impact growth performance. We hypothesized that supplementing MLP diets with phytogenics may reduce the negative effects of these diets on growth. The objective of this study was to investigate the effect of a phytogenic water additive (PWA; Herbanimal®) on growth performance, blood metabolite and gene expression of amino acids transporters in pigs fed with MLP diets. Forty-eight weaned barrows were allotted to six dietary treatments (n = 8) for 4 weeks: >CON-NS: standard protein diet-no PWA; CON-LS: standard protein diet-low PWA dose (4 ml/L); CON-HS: standard protein diet-high PWA dose (8 ml/L); LP-NS: low protein diet-no PWA; LP-LS: low protein diet-low PWA dose (4 ml/L); LP-HS: low protein diet- high PWA dose (8 ml/L). Feed intake and body weight were recorded daily and weekly, respectively. At week 4, blood and tissue samples were collected and analyzed for metabolites using a chemistry analyzer and amino acid transporters using qPCR, respectively. The data were analyzed by univariate GLM (SPSS®) and the means were separated using paired Student’s t-test corrected by Benjamini-Hochberg. Pigs fed CON-HS improved the average daily gain and serum calcium and phosphorus concentrations compared to CON-NS. Pigs fed LP-LS had higher serum phosphorus and blood urea nitrogen compared to the pigs fed with LP-NS. The mRNA abundance of SLC7A11 in the jejunum was lower in CON-LS and CON-HS compared to CON-NS. Additionally, mRNA abundance of SLC6A19 in the jejunum of pigs fed with LP-LS was higher compared to LP-NS and lower in CON-HS relative to pigs fed with CON-LS. In conclusion, PWA improved the growth performance of pigs fed standard protein diets but not low protein diets. Further, the PWA improved the concentrations of blood calcium and phosphorous in pigs fed MLP diets.

Experimental Group

The effect of the plant ecdysteroid-containing preparation of Leuzea extract on the metabolism and productivity of barrows (three-breed crossbreeds Landrace × large white × Duroc) during fattening on low-protein diets enriched with essential amino acids from 130 to 212 days old was studied for the first time. In the control and experimental groups, a low-protein barley-wheat diet with the addition of essential amino acids contained (g / kg) crude protein - 108 g, metabolic energy - 12.5 MJ, lysine - 7.6 g, threonine - 5.4 g, methionine - 5.2 g. In the experimental group, liquid extract of leuzea was introduced into the feed, at the rate of 190 mg / kg. Feeding the barrows during the fattening period of the leuzea extract contributed to an increase in the efficiency of the use of nutrients in biosynthetic processes in animals. In the barrows of the experimental group, the concentrations of total protein (P≤0.05), albumin (P≤0.05), creatinine (P≤0.05), lactate dehydrogenase, creatine kinase, alkaline phosphatase activity at a lower level were statistically significantly higher urea (16.1%, P≤0.05) and glucose (P≤0.05). In the experimental group, during the period of fattening, the average daily gain in live weight was higher (by 10.2%, P≤0.05), the yield in the carcass of muscle tissue (P≤0.05), the indices of lean and meatiness, and lower the cost of feed (P≤ 0.05), crude protein (P≤0.05) and exchange energy (P≤0.05) per 1 kg of gain in live weight, output of subcutaneous adipose tissue and internal fat in comparison with the control. It was concluded that the use of a leuzea extract containing phytoecdysteroids, while feeding low-protein diets enriched with lysine, methionine and threonine, corrects metabolic processes, stimulating the biosynthesis of meat components, and thereby contributes to an increase in the productivity of barrows during fattening.
