Objective: This study was conducted to evaluate the effects of diets containing different wet rice distillers’ by-product (RDP) levels on growth performance, nutrient digestibility, blood profiles and gut microbiome of weaned piglets.Methods: A total of 48 weaned castrated male crossbred pigs, initial body weight 7.54±0.97 kg, and age about 4 wks, were used in this experiment. The piglets were randomly allocated into three iso-nitrogenous diet groups that were fed either a control diet, a diet with 15% RDP, or a diet with 30% RDP for a total of 35 days. Chromium oxide was used for apparent digestibility measurements. On d 14 and d 35, half of the piglets were randomly selected for hemato-biochemical and gut microbiota evaluations.Results: Increasing inclusion levels of RDP tended to linearly increase (p≤0.07) average daily gain on d 14 and d 35, and decreased (p = 0.08) feed conversion ratio on d 35. Empty stomach weight increased (p = 0.03) on d 35 while digestibility of diet components decreased. Serum globulin concentration decreased on d 14 (p = 0.003) and red blood cell count tended to decrease (p = 0.06) on d 35, parallel to increase RDP levels. Gene amplicon profiling of 16S rRNA revealed that the colonic microbiota composition of weaned pigs changed by inclusion of RDP over the period. On d 14, decreased proportions of Lachnospiraceae_ge, Ruminococcaceae_ge, Ruminococcaceae_UCG-005, and Bacteroidales_ge, and increased proportions of Prevotellaceae_ge, Prevotella_2, and Prevotella_9 were found with inclusion of RDP, whereas opposite effect was found on d 35. Additionally, the proportion of Lachnospiraceae_ge, Ruminococcaceae_ge, Ruminococcaceae_UCG-005, and Bacteroidales_ge in RDP diets decreased over periods in control diet but increased largely in diet with 30% RDP.Conclusion: These results indicate that RDP in a favorable way modulate gastrointestinal microbiota composition and improve piglet performance despite a negative impact on digestibility of lipids and gross energy.

Background: The effects of the probiotics vary with the doses and strains used for this reason, a study was conducted over 35 days to determine the effect of live yeast supplementation in the diet of growing rabbits on growth performance and apparent nutrient digestibility.Methods: A total of 60 New Zealand and California rabbits (5 weeks old, average body weight 0.881±0.015 kg) were housed in 30 cages. They were fed with a control diet based on alfalfa and maize or barley grains and supplemented with Procreatin®7 (Saccharomyces cerevisiae CNCM I 1077) or Biosaf® SC47 (Saccharomyces cerevisiae NCYC Sc47) at three doses, namely 0, 6.4, or 12.8 ×109 CFU per kg basal diet.Result: The higher yeast concentration had a positive effect (P less than 0.01) on final body weight (BW), average daily gain (ADG) and carcass weight (CW). However, there were no significant differences in dry matter intake. As a result of this, the feed conversion ratio (FCR) decreased (P less than 0.01). Significant increases (P less than 0.05) in nutrient digestibility (DM, OM, NDF and ADF) were observed with both grains. The use of yeast in maize and barley-based diets of rabbits has positive effects on growth performance and nutrient digestibility.

This study was conducted to investigate the influence of replacing part of soybean meal (SBM) with 15% treated rapeseed meal (tRSM) on growth performance, blood parametres and nutrient digestibility in young growing pigs. A total of 12 crossbred growing pigs (Slovakian White x Landrace) with an average initial body weight of 15.70 ± 1.83 kg were divided into two dietary treatments according to their body weight and sex (six pigs in each group). The experiment lasted 34 days. The rapeseed meal was treated with the product that neutralizes the negative effects of glucosinolates contained in rapeseed by-products for pigs feeding. In our study, we did not observe negative effects of tRSM on body weight, average daily gain and feed conversion ratio. In blood profile, serum urea, albumin, glucose and total chlosterol were not influenced by dietary tRSM treatment. Concentration of total proteins was decreased at the end of the experimental period in the experimental group (P<0.01). For apparent total tract digestibility acid-insoluble ash was used as marker. Partially replacing of SBM with tRSM had no significant negative effects on the apparent total tract digestibility of dry matter, crude protein and crude fat. Finally, the inclusion of 15% of treated RSM in growing pig diets had no negative effects on growth performance, nutrients digestibility and selected blood characteristics.

Weaning Pigs

A total of 180, 4-week-old crossbred weaning piglets ((Yorkshire × Landrace) × Duroc; 6.67 ± 1.40 kg) were used in a 42 day experiment to evaluate the effect of dietary probiotics (Lactobacillus plantarum BG0001) on growth performance, nutrient digestibility, blood profile, fecal microbiota, and noxious gas emission. All pigs were randomly allotted to one of four treatment diets in a completely randomized block design. Each treatment had nine replicates with five pigs/pen (mixed sex) Designated dietary treatments were as: (1) basal diet (NC), (2) NC + 0.2% antibiotics (chlortetracycline) (PC), (3) NC + 0.1% L. plantarum BG0001 (Lactobacillus plantarum BG0001) (NC1), (4) NC + 0.2% L. plantarum BG0001 (NC2). On d 42, BW and G:F were lower (p < 0.05) in pigs fed NC diet compared with PC diet and probiotic diets. Throughout this experiment, the average daily gain increased (p < 0.05) in pigs when fed with PC and probiotic diets than the NC diet. The average daily feed intake was higher (p < 0.05) in pigs fed PC diet during day 0–7 and 22–42, and probiotic diets during day 0–7 compared with NC diet, respectively. The Lactobacillus count was increased and Escherichia coli count was decreased (p < 0.05) in the fecal microbiota of pigs fed probiotic diets, and E. coli were decreased (p < 0.05) when fed a PC diet compared with the NC diet on day 21. Moreover, the apparent total tract nutrient digestibility, blood profile, and the concentration of noxious gas emission had no negative effects by the probiotic treatments. In conclusion, dietary supplementation with L. plantarum BG0001 significantly improved the growth performance, increased fecal Lactobacillus, and decreased E. coli counts in weaning pigs.

The purpose of this study was to evaluate the effects of dietary supplementation of Quillaja saponin (QS) on growth performance, nutrient digestibility, fecal microbiota, and fecal gas emission in growing pigs. A total of 50 crossbred growing pigs [(Yorkshire × Landrace) × Duroc] with an initial body weight of 23.83 ± 1.95 kg were randomly assigned to 1 of 2 treatments for a 56-day trial with 5 replicate pens per treatment and 5 pigs (2 barrows and 3 gilts) per pen. Dietary treatments including control diet and control diet supplemented with 200 mg/kg QS. The average daily gain was significantly increased during days 0-56, while the fecal ammonia emission on day 56 and fecal coliform bacteria counts on day 28 were significantly decreased in pigs fed with QS containing diet. However, dietary supplementation of QS had no significant effects on apparent total tract digestibility. In conclusion, dietary supplementation of 200 mg/kg QS had beneficial effects on growth performance, fecal microbiota, and fecal gas emission in growing pigs. Considering the carry-over effects, the adaption period should be at least 28 days when supplementing 200 mg/kg QS to the diet of growing pigs for improving the growth performance.

The objective of this study was to evaluate the effect of replacing cereals and protein concentrates in a high-cereal concentrate (control) for light lambs with corn distiller’s dried grains with solubles (DDGS; 18%), dried citrus pulp (DCP; 18%), and exhausted olive cake (EOC; 8%) in a byproduct (BYP) concentrate on growth performance, digestibility, ruminal fermentation, and plasma metabolites. Two homogeneous groups of Lacaune lambs (13.8 kg ± 0.25 kg) were fed one of each concentrates and barley straw ad libitum until reaching about 26 kg body weight. There were no differences between groups on feed intake, average daily gain, or feed conversion ratio, but the control diet had greater (p < 0.001) dry matter digestibility. Diet had no effect on post-mortem ruminal pH and total volatile fatty acid concentrations and profile, but NH3-N concentrations were lower (p = 0.003) for the BYP-fed group compared with the control one. However, plasma concentrations of amino acids, total proteins, urea, and hepatic enzymes were not affected by the diet. In conclusion, 44% of feed ingredients in the concentrate for light lambs can be replaced with a mixture of corn DDGS, DCP, and EOC without negatively affecting growing performance and animal health.

This study was conducted to evaluate effects of rare earth element-enriched yeast (RY) on growth performance, nutrient digestibility, blood profile, and fecal microbial flora in finishing pigs. A total of 100 finishing pigs [(Landrace × Yorkshire) × Duroc] were used in a two-phase feeding trial. Pigs were randomly assigned to five treatments according to their initial body weight (five pens per treatment, two gilts and two barrows per pen). Treatments were basal diets, free of antibiotics [negative control (NC)]; NC + 500, 1000, and 1500 mg kg−1, respectively, of RY; antibiotics diets, NC + 500 mg kg−1 of tiamulin [positive control (PC)]. Overall, average daily gain (ADG) and gain to feed ratio (G:F) increased linearly with increasing level of RY in diets. At the end of the experiment, blood lymphocyte concentration and apparent total tract digestibility of dry matter and gross energy increased linearly in pigs fed the increasing level of RY in diets. The better ADG, G:F, and fecal Lactobacillus counts were observed in both RY and PC groups compared with the NC group. In conclusion, diets with RY improved growth performance, digestibility, blood lymphocyte counts, and fecal Lactobacillus counts in finishing pigs, and RY may be considered as an alternative to antibiotics.

A 56 –day study was conducted to determine the growth performance and nutrient utilization of broiler chickens fed with two varieties (white and yellow) of cassava grit based diets. A total of 240 one day- old unsexed Arbor acre broiler chicks were assigned to eighty dietary treatments in a 2 x 4 factorial arrangement using completely randomized design. Diets were formulated to include two varieties of cassava, TME 419 (white) and TMS 01 1368 (yellow) at four inclusion levels (0, 25, 50 and 75%). Each treatment consisted of 30 birds and three replicates of 10 birds each. Data was collected on growth performance and nutrient digestibility at the end of the starter (4th week) and finisher (8th week) phases. At the starter phase, birds fed 50% white cassava grits diet had the highest (P < 0.05) final weight and weight gain (730.00 and 693.67g/bird). At the finisher phase, birds fed 50% yellow cassava grits diet had the highest (P < 0.05) final weight and weight gain (2235.60 and 1454.00g/bird), respectively while the least final weight and weight gain values (2008.80 and 1267.80g/birds) were obtained in birds fed the control diet. At the starter phase, birds fed 75% white cassava grits diet had the best (P < 0.05) feed conversion ratio of 2.18, while birds fed 25% yellow cassava grits diet as well as those fed the control diet had the least (P < 0.05) feed conversion ratio of 2.62 and 2.51 respectively. Birds fed 50% yellow as well as those fed 75% yellow cassava grits diets had the highest dry matter and crude fibre digestibility at the starter and finisher phases, respectively. In conclusion the substitution of maize with white cassava grits up to 50% level improved growth performance at the starter phase. However, either white or yellow cassava can be substituted for maize up to 75 % at the finishing phase.

Abstract This experiment evaluated varying levels of Amarula (Sclerocarya birrea A. Rich) nut cake (ANC) on growth performance, nutrient digestibility and carcass characteristics in pigs. Thirty Large White × Landrace (LW × LR) pigs were stratified by weight (average live weight of 20 ± 5 kg) and randomly allocated to the five experimental diets that contained 0 (control), 50, 100, 150 and 200 g ANC/kg DM. Each pig served as a replicate unit, housed individually. Bodyweight, feed intake, average daily gain (ADG) and feed conversion ratio (FCR) were recorded weekly throughout the trial period. On completion of the growth trial, following a 3-day adaptation, a nutrient digestibility study was conducted over 5 days. Thereafter, pigs were fasted for twelve hours, weighed, slaughtered, and carcass samples were collected for analysis. Feed intake was not affected by dietary treatment, but ADGs were reduced at ANC levels > 15%, resulting in poor FCR. Protein digestibility was reduced at ANC levels > 15%, while ether extract and fibre levels increased. Warm and cold carcass weights were lower at ANC levels > 15, with improved meat redness and lightness. It was concluded that ANC could replace SBM in the diet of growing pigs at less than 15% inclusion level.

Abstract A body of evidence suggests that low-protein diets in swine have benefits in view of environmental stewardship and economic returns. The present study was performed to evaluate essential amino acid (EAA) supplementation in the diets with reducing crude protein (CP) concentrations on growth performance in fattening pigs. We hypothesized that a low-CP diet with elevated EAA concentrations would result in similar growth performance in fattening pigs compared with a normal CP diet. Eighty finishing pigs with initial body weight (BW) of 72.0 ± 5.34 kg were assigned in a randomized complete block design with 5 replicates to test 4 dietary treatments: 1) 15.5% CP with EAA concentration at 109% of NRC requirement (control); 2) 14.0% CP with EAA concentration at 111% of NRC requirement (EAA111); 3) 14.0% CP with EAA concentration at 113% of NRC requirement (EAA113); and 14.0% CP with EAA concentration at 115% of NRC requirement (EAA115). The diets were isocaloric, whereas crystalline amino acids, L-Lys, L-Met, L-Thr, L-Trp, and L-Val were added to the diets to achieve the varying levels of EAA in the treatments. The Lys-to-net energy ratio in the diets was maintained at 3.06, 3.12, 3.18, and 3.24 to the control, EAA111, EAA113, and EAA115, respectively. Dietary treatments did not affect final BW. Additionally, average daily gain, average daily feed intake, and feed conversion ratio (FCR) were similar across the treatments. On average, pigs fed the control and EAA111 numerically decreased FCR compared to those fed EAA113 and 115 (3.21 vs. 3.35, respectively; P = 0.46). Total feed cost throughout the experiment was $9.0/head lessen in EAA111 relative to the control; however, total feed costs to EAA113 and EAA115 were greater than the control. In summary, a low-CP diet with increased EAA supplementations did not have any negative impact on growth performance of fattening pigs.

This study investigated the effects of excessive or restrictive energy on growth performance, meat quality, intramuscular fat (IMF) deposition, and related gene expression in finishing Ningxiang pigs. A total of 36 Ningxiang pigs (43.26 ± 3.21 kg) were randomly assigned to three treatments (6 pens of 2 piglets per treatment) and fed by one of three dietary treatments until the pigs of each treatment weighed approximately 75 kg equally. The three treatments were control diet (digestible energy, DE:13.02 MJ/kg, CON), excessive energy diet (DE 15.22 MJ/kg, EE), and restrictive energy diet (DE 10.84 MJ/kg, RE). Results showed that EE improved average daily gain (ADG) and feed conversion ratio (FCR) (p < 0.01), while nothing significantly changed by RE except FCR increasing (p < 0.01). EE increased the content of IMF and triglycerides (TG) (p < 0.05), L*24h and b*45min (p < 0.01), while decreasing cooking loss and meat tenderness in longissimus thoracis (LT) (p < 0.05). b*24h was significantly increased with the increase of energy level (p < 0.01). Meanwhile, EE increased the cross-sectional area (CSA) of muscle fiber and the mRNA expression of myosin heavy chain (MyHC) IIb, acetyl CoA carboxylase (ACC), fatty acid synthase (FAS), and adipocyte fatty-acid binding protein (FABP4) (p < 0.05). In addition, throughout: A diet supplemented with excessive energy promoted IMF deposition by positively changing lipogenic potential while decreasing tenderness by increasing glycolytic muscle fibers, which together affected meat quality. In terms of growth performance and meat quality, the present study suggests that the low-energy diet is suitable for finishing Ningxiang pigs.
