The study was aimed to evaluate the effects of dietary inclusion of an enzyme blend on growth performance, apparent total track digestibility (ATTD) of dry matter (DM), nitrogen (N), gross energy (GE), fecal microbial population, noxious gas emissions and meat quality of pigs fed corn–soybean meal-based diets for a 16-week feeding trial. A total of 180 growing pigs (body weight of 23.3 ± 2.51 kg) were used and randomly allotted to one of three dietary treatments (positive control (PC, basal diet); negative control (NC, −150 kcal/kg of PC); A1 (NC + 1% enzyme blend)). Overall, dietary inclusion of the enzyme blend increased (p < 0.05) body weight, average daily gain and gain:feed ratio without effecting average daily feed intake. An increase was observed in ATTD of DM (p = 0.027) and GE (p = 0.026) at week 16 and 6, respectively. Dietary inclusion of the enzyme blend increased the beneficial effects on fecal microbiota counts such as Lactobacillus with a reduced presence of E. coli during the entire experiment (p < 0.05). Further, positive effects (p < 0.05) were observed on back-fat thickness and carcass weight of pigs, along with the results of reduced levels of NH3 emissions (p = 0.032) at week 16. Thus, the study suggested that the dietary enzyme blend supplement had improving effects on growth performance, ATTD of nutrients, fecal microbial counts and meat quality in pigs.

Abstract This study was carried out to assess the effects of dietary supplementation of enzymatic bio-conversion of Scuterallia baicalensis (SB) extract on the growth performance, nutrient digestibility, fecal microbiota, fecal gas emission, blood hematology, and antioxidative indicators in growing pigs. A total of 200 crossbred pigs [(Landrace × Yorkshire) × Duroc] with an initial body weight of 24.52 ± 1.99 kg were used in a 42-day experiment with a completely randomized block design. Pigs were randomly divided into 4 treatment groups with 10 replicate pens per treatment and 5 animals per pen (2 barrows and 3 gilts). There were four diet conditions: 1) CON, basal diet; 2) TRT1, basal diet + 0.1% apramycin; 3) TRT2, basal diet + 0.1% SB extract; 4) TRT3, basal diet + 0.1% enzymatic bio-conversion of SB extract. The pen was taken as the experimental unit. Tukey’s multiple range test was used for evaluation of differences among the treatments. Compared with the CON group, TRT1 or TRT3 groups had higher final body weight (BW) (P = 0.074) and average daily gain (ADG) (P = 0.075), and lower feed conversion ratio (FCR) (P = 0.054). The apparent total tract digestibility (ATTD) of dry matter (DM) (P = 0.095) in TRT1 group was higher than that in CON group. Serum glutathione peroxidase (GPX) (P = 0.047) and glutathione (GSH) (P = 0.074) concentrations in TRT3 group were higher than those in CON or TRT1 groups. However, there were no significant differences in fecal microbiota, fecal gas emission, and blood hematology among all dietary groups. A positive correlation between apramycin supplementation in the diet and ADG and the ATTD of DM were observed. A positive correlation between enzymatic bio-conversion of SB extract supplementation in the diet and ADG and the concentration of GPX and GSH in serum were also observed.

Yeast Concentration

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.

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.

Fermented Feed

Abstract As an alternative to antimicrobial growth promoters, fermented feed (FF) has been continuously developed for two decades; however, its effects on feed, performance, digestibility, and meat quality of pigs have yet to be systematically and comprehensively evaluated. This study aimed to (i) quantitatively evaluate the effects of fermentation on nutritional components of feed stuffs; (ii) quantitatively evaluate the effects of FF on pig growth performance, digestibility, and meat quality; and (iii) explore the dose–effect relationship. From PubMed and Web of Science (searched range from January 1, 2000 to April 4, 2019), we collected 3,271 articles, of which 30 articles (3,562 pigs) were included in our meta-analysis. Our analysis revealed that fermentation significantly increased the CP content in feed (P &lt; 0.05). For weaned piglets and growing pigs, FF significantly improved ADG, G:F, DM digestibility, N digestibility, and energy digestibility (P &lt; 0.05). However, compared with the basal diet, FF had no significant effects on growth performance and nutrient digestibility in finishing pigs (P &gt; 0.05). In the subgroup analyses, fermented ingredients increased the growth performance of weaned piglets and growing pigs, and fermented additives promoted the growth of pigs at all stages. The dose–effect analysis confirmed that the optimal doses of fermented ingredients and additives were 8% and 0.15%, respectively. Furthermore, FF had beneficial impacts on meat quality through increased lightness, redness, marbling and flavor and reduced drip loss (P &lt; 0.05). In conclusions, FF improved growth performance and meat quality primarily due to its positive effects on nutritive value and utilization.

This study was conducted to evaluate the effect of supplementation of different flavors (apple and anise) on growth performance, nutrient digestibility, blood profiles, and carcass quality in growing–finishing pigs. A total of 96 growing pigs [(Yorkshire × Landrace) × Duroc] with an average body weight (BW) of 28.2 ± 0.7 kg were randomly assigned to one of the following three treatments: (1) CON, basal diet; (2) APF, basal diet + 0.05% apple flavor; (3) ANF, basal diet + 0.05% anise flavor, according to their BW and sex in this 15 wk experiment. There were eight replications (pens) per treatment and four pigs per pen (two barrows and two gilts). During week 0–5, pigs fed ANF diets had greater (p < 0.05) average daily gain (ADG) and average daily feed intake than those fed CON and APF diets. Dietary ANF treatment increased (p < 0.05) ADG during 0–15 wk compared with CON treatment. At the end of 5 wk, the apparent total tract digestibility of nitrogen in ANF treatment was improved (p < 0.05) compared with that in CON treatment. Dietary treatments did not affect the studied traits of carcass and meat quality. The inclusion of anise flavor increased ADG, but apple flavor had no effect on growth performance in growing–finishing pigs.

This study was conducted to evaluate the effect of carbohydrases on growth performance, nutrient digestibility, blood profiles, and fecal microbiota in weanling pigs fed reduced energy diet. A total of 160 crossbred [(Yorkshire × Landrace) × Duroc)] weanling pigs with an initial body weight (BW) of 7.23 ± 1.08 kg were used in this 42 d trial. Pigs were randomly allocated in one of the following four dietary treatments: (1) CON, basal diet [net energy (NE) 2545 kcal kg−1]; (2) LE, low-energy diet (NE 2470 kcal kg−1); (3) LEC1, LE + 0.1% carbohydrase; and (4) LEC2, LE + 0.2% carbohydrase based on the sex and BW. There were eight replications (pens) per treatment with five pigs (two male and three female) per pen. During day 0–7, pigs fed with LE diet had lower (P < 0.05) average daily gain (ADG) and average daily feed intake than those fed with CON and LEC2 diets. LE group reduced (P < 0.05) ADG throughout the experiment compared with CON and LEC2 groups. LE group reduced (P < 0.05) the digestibility of dry matter, nitrogen, and gross energy compared with LEC2 diet. Taken together, LE diet caused detrimental effects on growth performance and nutrient digestibility in weanlings, whereas the addition of carbohydrases (0.2%) partially counteracted these negative effects.

The present experiment was to evaluate the effects of dietary Spirulina (SP) supplementation in growing pigs. A total of 140 pigs [(Landrace × Yorkshire) × Duroc, 25.32 ± 1.36 kg] were randomly distributed to one of four treatments: control, basal diet; treatment 1, basal diet + 0.025% SP; treatment 2, basal diet + 0.050% SP; and treatment 3, basal diet + 0.100% SP. Growing pigs fed 0.050% SP diet had greater (P < 0.05) body weight and fecal Lactobacillus counts compared with pigs fed basal diet. Average daily gain and gain to feed ratio were greater (P < 0.05) in pigs fed 0.050% and 0.100% SP diets as compared with pigs fed basal diet. The apparent total tract digestibility (ATTD) of dry matter (DM) and superoxide dismutase (SOD) activity for pigs fed 0.050% SP diet tended to increase compared with pigs fed basal diet (P < 0.10). Pigs fed 0.025%, 0.050%, and 0.100% SP had a higher (P < 0.05) glutathione peroxidase (GPx) activity than pigs fed basal diet. In conclusion, SP supplementation improved growth performance and ATTD of DM, increased the SOD and GPx activity, and enhanced the fecal Lactobacillus counts in growing pigs.

This study is to evaluate the effects of mineral Detoxified nano-Sulfur Dispersion (DSD) on growth performance, fecal score, fecal microbial, gas emissions, blood profile, nutrient digestibility and meat quality in finishing pigs. A total of 160 pigs with an initial body weight of 54.90 ± 5.10 kg were randomly assigned to 2 treatments include basal diet and basal diet with 10ppm DSD. During 10 week trial there were no differences in body weight (BW), average daily gain (ADG), average daily feed intake (ADFI) and gain to feed ratio (G:F) between the control and DSD groups. Also, the fecal score, fecal microbiota, gas emission was not affected by DSD diet. Dietary inclusion of DSD tended to increase water holding capacity and decrease cooking loss and drip loss. At week 5, serum concentrations of glucose, calcium, total cholesterol, high-density level were increased, and triglyceride concentration was reduced in pigs fed with DSD than control diets. In summary, the inclusion of dietary DSD in the finishing pig diet has improved serum Ca, glucose concentrations and lipid profiles as well as it improves some meat quality traits.

Abstract A total of 168 one-day old broilers (average BW 46.4 ± 0.6 g) were selected to determine effects of natural capsaicin extract (NCE) as a substitute for chlortetracycline (CTC) on performance, antioxidant capacity, immune function and meat quality of broilers [Founded by NSFC (31772612)]. Broilers were randomly allotted into 3 dietary treatments (n = 7) including a corn-soybean meal basal diet (CON), a basal diet + 75 mg/kg CTC (CTC), and a basal diet + 80 mg/kg NCE (NCE). The experiment contained phase 1 (day 1 to 21) and 2 (day 22 to 42). Compared with CON, broilers from NCE showed higher average daily gain at all stages (P &lt; 0.05). On day 42, organic matter, crude protein and gross energy digestibilities of broilers from NCE were higher than those from the other two groups (P &lt; 0.05). Higher percentage of bursa of Fabricius was observed in broilers fed NCE diets compared with CON (P &lt; 0.05). Trypsin and lipase activities in the pancreas of broilers from NCE were higher than those from CON (P &lt; 0.05). Breast muscle of broilers fed NCE diets showed lower L* values compared with CON (P &lt; 0.05). Broilers from NCE also showed higher levels of serum total antioxidant capacity, glutathione peroxidase, superoxide dismutase, lower levels of interleukin-1β and tumor necrosis factor-α compared with broilers offered CON diets (P &lt; 0.05). Compared with CON, lower concentrations of serum urea-N, low-density lipoprotein cholesterol and total cholesterol, higher growth hormone level were observed in broilers fed NCE diets (P &lt; 0.05). In conclusion, supplementing 80 mg/kg of NCE to diets could improve growth performance, nutrient digestibility, antioxidant and immune function, and meat quality of broilers. Moreover, broilers fed NCE diets exhibited similar growth performance and health status to those offered chlortetracycline (CTC) diets.

Turmeric residue (TR), which is obtained from the extraction process of curcuminoids, may remain biological active compounds. This study was conducted to examine the effects of the TR on hematological parameters, nutrient digestibility, and growth performance in hybrid catfish (Clarias gariepinus × Heterobranchus bidorsalis). Three experimental diets were formulated denoted as follows: BD (Basal diet), BTR1D (BD plus 1% TR powder), and BTR2D (BD plus 2% TR powder). Twelve juvenile hybrid catfish with an initial body weight of 180 g were allocated to each of the 6 concrete tanks (350-L holding capacity), resulting in two replicate tanks per dietary treatment. For 4 weeks, the fish were hand-fed the experimental diets to apparent satiation twice daily. The results showed that the final body weight and weight gain tended to increase in fish fed TR-supplemented diets, and significant differences were recorded in the BTR2D group as compared to the BD group (P < 0.05). In contrast, FCR values were decreased in fish fed BTR1D and BTR2D in comparison with those fed BD, and the FCR value of the BTR2D group was significantly lower than that of the BD group (P < 0.05). Hemoglobin concentration, white blood cell count and protein and lipid apparent digestibility coefficients were higher in fish fed TR-supplemented diets than those fed BD. These results indicated that dietary supplementation of the TR was beneficial to hematological parameters, nutrient digestibility, growth performance, and feed utilization in hybrid catfish. The positive effects of the BTR2D on fish performances in the present study suggest that supplementation of the TR at the ratio of 2% in the diet may be necessary for hybrid catfish practical culture.
