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.

Abstract Increased feed cost, post-weaning diarrhea, and nitrogen excretion are challenging the modern swine industry. Very low-protein (LP) diets (>4% units reduced protein) may reduce feed cost, diarrhea and nitrogen excretion; however, these diets impair growth performance of pigs despite supplementation of limiting amino acids (i.e., lysine, threonine, methionine and tryptophan). The objective of this study was to investigate the effect of valine, isoleucine and combination of both supplemented to VLP diet on growth, thermal radiation, and gut development in young pigs. Forty three-week-old weaned barrows were weighed (6.75 ± 0.14 kg) and randomly assigned to five groups (8 pigs/group) including: 1) standard diet or positive control (PC), 2) LP diet, 3) LP + valine (LPV), 4) LP + isoleucine (LPI) and 5) LP + both valine and isoleucine (LPVI) for five weeks. Daily feed intake and weekly growth characteristics were measured and weekly thermal images were captured. All pigs were euthanized at week 5 and tissue samples collected. All data were analyzed with univariate GLM followed by Tukey’s post-hoc test (SPSS®). Compared to PC, final body weight, average daily gain, average daily protein intake and gain:feed ratio were reduced in LP group, but feeding pigs with LPVI partially or completely recovered these parameters. Pigs fed with LPVI had higher thermal radiation than those fed with PC, LP, and LPI on days 28 and 35 of study and had a greater the area under the curve for thermal radiation than LP and LPI. Duodenal villus width and crypt depth, and ileal villus height were decreased in LP relative to PC, but LPVI either partially or fully recovered these measurements. In conclusion, supplementing a combination of valine and isoleucine recovered the negative effects of very low-protein diets on growth performance and gut development, but increased the thermal radiation in weaned pigs.

Abstract We examined the effects of replacing corn silage (CS) with reconstituted alfalfa hay (AH) or beet pulp (BP) in the starter diet on the nutrient intake and digestibility, growth performance, rumen fermentation characteristics, selected blood metabolites, and health status in Holstein dairy calves. Newborn female calves (n = 54; 3 d of age; 39.8 ± 1.36 kg BW) were assigned randomly to 3 groups receiving starter diets containing CS [10% dry matter (DM) basis; CS diet) and reconstituted AH (10% DM, RAH diet) or BP (10% DM; RBP diet). The starter diets had the same nutrient composition and DM content. The calves were weaned on day 50 and the study continued until day 70. Nutrient intake, body weight (at weaning and at the end of the study), daily weight gain, feed efficiency, and body measurements (including heart girth, withers height, body length, body barrel, hip height, and hip width) were not affected by the diet (P > 0.05). Health-related variables including rectal temperature, fecal score, and general appearance score were not influenced by the diets (P > 0.05). During the postweaning period, apparent total tract digestibility of DM, organic matter, and crude protein were higher for RBP (P = 0.001); however, digestibility of neutral detergent fiber was lower in RAH compared with CS or RBP (P = 0.001). Daily amount of nutrient digestibility did not change across the diets (P > 0.05). Rumen fluid pH and total volatile fatty acid concentration and profile were not different across the diets after weaning (P > 0.05). Calves fed RAH or RBP had higher blood concentration of β-hydroxy butyric acid compared with CS only before weaning (P = 0.03). Blood albumin concentration was higher for RBP compared with CS or RAH during the preweaning (P = 0.006) and overall (P = 0.005) periods; however, it was lower for CS compared with RBP after weaning (P = 0.03). Concentration of other blood variables including glucose, blood urea N, total protein, and globulin did not change across the diets (P > 0.05). Calves, in general, were healthy, and replacing CS with RAH or RBP in the starter diet had no beneficial effect on their feed intake or growth performance indicating that CS and reconstituted AH or BP can be used interchangeably in dairy calf starter diets until 70 d of age, allowing dairy producers more choices in selecting the feed ingredients.
