The study was conducted to evaluate the effects of olive leaves with probiotics (OLP) on growth performance, carcass characteristics, meat quality, blood parameters and oxidative stability of meat in broiler. A total of 160 day old, unsexed Cobb-500 chicks were distributed in to five dietary treatment groups: Control (Basal diet), OLP-1 (Basal diet + 0.4% OLP, DM basis), OLP-2 (Basal diet + 0.8% OLP, DM basis), OLP-3 (Basal diet + 1.2% OLP, DM basis) and OLP-4 (Basal diet + 1.6% OLP, DM basis) having 4 replications with 8 birds in each in a completely randomized design. Results showed that the live weight, overall average daily gain (ADG) increased significantly (p<0.05) in all treatment groups compared to control. The weekly feed conversion ratio (FCR) reduced significantly (p<0.05) in 0-14 days and the weekly ADG improved in 15-28 days. Blood cholesterol and high density lipoprotein (HDL) increased significantly (p<0.05) in all treatment groups except OLP-4 compared to control. The dressing percentage showed significant (p<0.05) difference among treatment groups and control. Organs weight were similar among treatment groups, although the breast meat and bursa weight differed significantly (p<0.05) in treatment groups. A significant increase (p<0.05) in meat crude protein (CP) and total ash content in treatment groups relative to control. Meat thiobarbituric acid reactive substances (TBARS) significantly (p<0.05) decreased at 0.8%, 1.2% and 1.8% during 1st, 2nd, 3rd weeks and in average value as well. Net return and benefit cost ratio (BCR) substantially increased in all treatment groups compared to control (p<0.05). Finally, dietary OLP supplementation improved growth performance, meat CP and ash content, increased blood cholesterol, HDL content, net rutrun and BCR while reduced meat TBARS value. Thus, olive leaf probiotics can be a potential source to be used as feed additive in broiler. Asian J. Med. Biol. Res. December 2020, 6(4): 650-658

A 6-week trial was conducted to investigate the effects of animal skin protein sources from swine and cattle on growth performance, body condition and blood characteristics in growing pigs. A total of 96 pigs (23.50 &plusmn; 0.61&nbsp;kg) were randomly allotted into four dietary treatment groups as follows: (1) basal diet (BD); (2) basal diet with 1.5% hydrolysed render meal (HRM); (3) basal diet with 1.5% swine skin meal (SSM); (4) basal diet with 1.5% cattle hide meal (CHM). There were six replicate pens per treatment with four pigs per pen. The average daily gain (ADG) was improved in response to SSM treatment compared with other treatments (P &lt; 0.05). Pigs fed with HRM, SSM and CHM diets showed increases in average daily feed intake (ADFI) and decreased gain-to-feed (G : F) ratios compared with pigs fed with BD (P &lt; 0.05). There were no differences in dry matter (DM), nitrogen (N), and energy (E) digestibility among treatments. The backfat thickness and lean percentage of pigs was unaffected by the treatments. Similarly, there was no difference in blood characteristics among treatments. In conclusion, the supplementation of SSM in growing pig diets improved the growth rate and Feed Intake (FI), but its usage in swine diets is limited by the poor protein quality. &nbsp;

Background and Aim: Weaning pigs normally suffer from many stressors which have impaired growth performance and immunity. Hydrolyzed yeast has been proposed as an alternative feed additive. The aim of this study was to investigate the effects of various levels of hydrolyzed yeast (HY) supplementation in the feed of weaning pigs on growth performance, diarrhea incidence, immunity, antioxidant capacity, and microbial populations. Materials and Methods: A total of 144 crossbred weaning pigs (Duroc × Landrace × Large White) with a mean body weight (BW) of 7.46 kg were randomly assigned to one of four treatments during a 5-week feeding trial. Treatments consisted of a basal diet without HY inclusion (control), or the basal diet supplemented with HY at 0.5, 1.0, and 1.5 g/kg of diet, respectively. Results: Piglets fed with 1.0 or 1.5 g/kg HY presented significantly increased BW (p=0.009) and decreased incidence of diarrhea (p=0.001). The final BW (p=0.012), average daily gain (p=0.094), and average daily feed intake (p=0.091) showed a linear improvement with the level of HY inclusion. However, the gain-to-feed ratio was unaffected by dietary treatments. Linear responses to the HY supplementation levels were also observed for blood urea nitrogen (p=0.030), total protein (p=0.017), lymphocyte percentage (p=0.064), catalase activity (p=0.089), malondialdehyde (MDA) level (p=0.001), Salmonella spp. (p=0.024), Escherichia coli (p=0.021), and Lactobacillus spp. (p=0.048). Dietary inclusion of HY at 1.0 and 1.5 g/kg resulted in increased immunoglobulin A and G secretions (p=0.042 and p=0.022, respectively) and decreased MDA concentration (p<0.01) and Salmonella spp. (p=0.026) and E. coli (p=0.050). Conclusion: It was concluded that HY inclusion at 1.0 and 1.5 g/kg in the diet of weaning pigs improve BW, immunoglobulin secretion, and antioxidant enzyme activity, whereas it lowers diarrhea occurrence, lipid peroxidation, and pathogenic bacteria in weaning pigs.

A total of 120 finish pigs [(Landrace × Yorkshire) × Duroc; 52.61 ± 2.37 kg] were randomly allotted into three treatments for a 70 d trial to evaluate the growth performance and fecal microbiota counts in finishing pigs. Treatment groups were (i) basal diet (CON), (ii) CON + 0.1% probiotic complex (TRT1), and (iii) CON + 0.2% probiotic complex (TRT2). Each treatment consisted of eight replicate pens with five pigs per pen. The average daily gain and fecal Lactobacillus counts of TRT2 were increased (P < 0.05) compared with CON treatment. The result showed that 0.2% complex probiotic was more effective than 0.1%.

The aim of this study was to evaluate the influence of vitamin and β-glucan supplementations on growth performance of growing-finishing pigs in Ben Tre province. A total of 36 post-weaned piglets (Duroc x Yorkshire-Landrace) with the initial live weight of 17.42 kg±0.26, was allotted into 3 treatments and 4 replications in a completely randomized design. There were three diets, including basal diet (BD) without any addition of β-glucan or vitamin (diet CT), the BD supplemented with vitamin (diet Vit) and the BD supplemented with β-glucan (diet Glu). The results on growth parameters indicated that final live weight (kg), weight gain (kg), and average daily gain (g/head/day) of pigs in the experimental diets were significantly higher (P<0.01) than those in the control treatment. FCR was lowest in Glu and highest in the control (P<0.01). Financial benefit based on feed and veterinary expenses was higher in the vitamin and β-glucan supplement diets than that of the control from 15.74% to 18.98%, respectively.

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.

In the present study, two experiments were conducted to (1) evaluate the effect of laminarin and/or fucoidan on ileal morphology, nutrient transporter gene expression and coefficient of total tract apparent digestibility (CTTAD) of nutrients and (2) determine whether laminarin inclusion could be used as an alternative to ZnO supplementation in weaned pig diets. Expt 1 was designed as a 2 × 2 factorial arrangement, comprising four dietary treatments (n 7 replicates, weaning age 24 d, live weight 6·9 kg). The dietary treatments were as follows: (1) basal diet; (2) basal diet+300 ppm laminarin; (3) basal diet+240 ppm fucoidan; (4) basal diet+300 ppm laminarin and 240 ppm fucoidan. There was an interaction between laminarin and fucoidan on the CTTAD of gross energy (GE) (P< 0·05) and the expression of sodium–glucose-linked transporter 1 (SGLT1/SLC5A1) and GLUT1/SLC2A1 and GLUT2/SLC2A2 (P< 0·05) in the ileum. The laminarin diet increased the CTTAD of GE and increased the expression of SGLT1, GLUT1 and GLUT2 compared with the basal diet. However, there was no effect of laminarin supplementation on these variables when combined with fucoidan. Expt 2 was designed as a complete randomised design (n 8 replicates/treatment, weaning age 24 d, live weight 7·0 kg), and the treatments were (1) basal diet, (2) basal diet and laminarin (300 ppm), and (3) basal diet and ZnO (3100 ppm, 0–14 d, and 2600 ppm, 15–32 d post-weaning). The laminarin diet increased average daily gain and gain:feed ratio compared with the basal diet during days 0–32 post-weaning (P< 0·01) and had an effect similar to the ZnO diet. These results demonstrate that laminarin provides a dietary means to improve gut health and growth performance post-weaning.

AbstractTwo isonitrogenous, isocaloric and isofibrous diets for finishing beef cattle differing only in their roughage constituents were compared in a feeding trial with Limousin bulls. A control maize silage (chop length = 9 mm) and wheat straw were the roughage sources of the former diet representing 0·23 and 0·09 of the dietary dry matter (DM) respectively. These roughage sources were fully replaced in the latter by the inclusion of a coarsely chopped maize silage (19 mm) at a level of 0·45 of the total dietary DM. Two balanced groups of 20 Limousin bulls (425·8 ± 20·3 kg live weight) each allotted in four pens were given the two diets ad libitum for a finishing period of 138 days. The different dietary roughages did not affect either bull growth performance (average daily gain = 1·39 ± 0·25 kg/day) or food conversion ratio. However, the diet containing the coarse silage significantly (P < 0·05) reduced the intake of both DM (8·30 v. 9·02 kg/day) and neutral-detergent fibre (NDF) (2·64 v. 2·92 kg/day). Although total ruminating time was similar for both diets, bulls given the coarse maize silage diet spent more time ruminating 1 kg of DM or NDF, probably due to the higher percentage of dietary forage NDF. No food selection activity towards specific chemical constituents was observed in either diet. Slaughter measurements and meat quality were satisfactory and unaffected by the type of dietary roughage. Based on cattle growth performance, feeding behaviour, and meat quality, the use of coarse maize silage as a dietary source of roughage can be considered a feasible alternative in beef cattle finishing.

SUMMARYThe present study was conducted to determine the effects of a polysaccharide of Atractylodes macrophala Koidz (PAM) as a dietary additive on growth performance, immunoglobulin concentration and IL-1β expression in weaned piglets. One hundred and twenty Landrace×Yorkshire piglets weaned at 28 days old (body weight 7·5±0·07 kg) were assigned to five treatment groups (three pens/group, eight piglets/pen) fed maize/soybean-based diets supplemented with 0, 3, 6 or 9 g of PAM/kg diet or antibiotics (0·4 g flavomycin/kg+0·13 g olaquindox/kg). The experimental period was 28 days. With increasing PAM supplementation levels, average daily gain was greater (quadratic, P<0·05) and the ratio of amount fed to live weight (LW) gain (feed/gain) improved (quadratic, P<0·05) during days 14–28 and overall, and diarrhoea incidence decreased (linear, P<0·05) during days 14–28. Supplementation of PAM also increased (quadratic, P<0·05) serum concentrations of interleukin (IL)-2 and IL-6 on day 14, and increased (quadratic, P<0·05) IL-1β expression in jejunal mucosa and lymph nodes. Concentrations of PAM between 6 and 9 g/kg presented the strongest bioactivity compared to the control group or antibiotic-fed group. These findings indicate that PAM is effective in improving growth performance and cytokine response, which suggests that PAM can be used as a diet additive for weanling piglets.

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.

Abstract. The aim of this study was to determine the effect of herbal feed additive on growth performance, carcass characteristics, the chemical composition of breast muscles and selected meat quality parameters in broiler chickens. The experiment was performed on 1080 Ross 308 chickens, which were randomly divided into six groups with six replicates per group. In experimental groups, dietary energy concentration was reduced by 0.10 or 0.25 MJ kg−1, and the diets were or were not supplemented with the Superliv herbal formula at 500 g t−1 of diet. A statistical analysis revealed that Superliv had a beneficial influence on the final body weights (BWs) of birds, average daily gain (ADG), feed conversion ratio (FCR), European Efficiency Index (EEI) and the proportion of heart relative to total carcass weight. However, meat acidity measured 15 min post mortem was higher in experimental groups. A decrease in dietary energy concentration contributed to a highly significant increase in the water-holding capacity (WHC) of meat and natural drip loss, an increase in pH15, an increase in color lightness, a decrease in redness, an increase in the fat content of meat, and a decrease in malondialdehyde (MDA) concentration.
