The aim of the study was to evaluate the effect of dietary probiotics on broiler growth performance, organ development and meat quality in replacing oxytetracycline. Dietary treatments were control (basal diet without additives), antibiotic (basal diet with 0.05% oxytetracycline), basal diet with Bacillus subtilis and basal diet with Lactobacillus spp. A total of 192 birds were randomly allotted to four dietary treatments with four replicates having 12 birds each. Feed and water were supplied ad libitum. The results of the current study revealed that growth performances of broiler did not show significant difference (P>0.05) among the treatments. Body weight and weight gain were numerically higher and FCR was numerically lower in broilers fed a diet containing 2 different single strains of probiotic than control. Though there were no treatment effects (P>0.05) on the weights of the liver, heart, kidney, spleen, gizzard, intestine and dressing percentage, but abdominal fat content was found significantly higher (P<0.05) in antibiotic treated group than that of single strain probiotic (Lactobacillus spp.) feeding group. Significant differences were also observed in meat color values where antibiotic fed broiler meat showed higher redness, lower lightness and yellowness and birds fed the control feed had higher lightness and yellowness of meat than probiotic fed chicken. TBA, PH and cooking loss were not affected by the treatments. Therefore, we concluded that use of selected probiotics resulted in improved performance parameters and reduced abdominal fat pad in broiler chickens. Moreover, addition of the probiotics in broiler diet for replacing antibiotic could be utilized for safe poultry meat production.Asian J. Med. Biol. Res. June 2017, 3(2): 233-239

Numerous efforts have been undertaken to develop suitable alternatives in order to counteract the anticipated drawbacks associated with the ban of antibiotic growth promoters (AGPs). The research purpose is to carry out the possible effect of mannan-riched fraction (MRF) and probiotic enhanced water as natural growth promoters (NGPs) on performance, relative organ weight, serum blood biochemistry, intestinal properties, and intestinal micro flora. 320 one-day-old Arbor Acres broiler were randomly allocated to 4 dietary treatments and 4 replicates of 20 birds per cage. four treatments used for research were dietary with control (T0), basal diet + MRF 80 g (T1), Drinking water + 2 mL/L combination feed additive (T2), and basal feed + MRF 80 g+ drinking water 2 mL/L combination feed additive (T3). The results showed that using mannan riched fraction (MRF) and combination with probiotic-enhanced liquid acidifier presented significant difference (P > 0.05) on body weight gain at 1-28 days and intestinal properties. On the blood biochemistry, the effect of supplementation began to reduce the amount of glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT) at 21 days periods. To sum up, the addition of mannan-riched fraction and combination with probiotic enhanced liquid acidifier doesn’t impacted on growth performance, and serum blood biochemistry but give significant effect on intestinal properties of broiler.

The present study was conducted to evaluate the effects of green tea by-product (GTB) and green tea plus probiotics (GT+P) on the growth performance, carcass characteristics, meat quality, blood parameters and immunity of growing–finishing pigs. In total, 80 crossbreed growing pigs were assigned to receive four dietary treatments for a period of 8 weeks. The dietary treatments were a basal diet (control), basal diet supplemented with 0.003% chlortetracycline (antibiotic), basal diet with 0.5% GTB (GTB) and basal diet containing 0.5% GT+P (GT+P). The results of our study indicated that bodyweight gain increased (P < 0.05) in response to the addition of GT+P to the basal diet. Crude protein and crude ash content, and shear values of loin meat were significantly (P < 0.05) increased in the GT+P group, although moisture and juiciness were decreased (P < 0.05). The GTB group had higher (P < 0.05) serum glucose concentrations, whereas the GT+P exhibited lower (P < 0.05) insulin concentrations. The values of thiobarbituric acid-reactive substances of fresh loin meat and meat that had been preserved for 1 week were lower (P < 0.05) in the GT+P group than those of the control and GTB groups. The growth of spleen cells incubated in concanavalin A (Con A) and lipopolysaccharide (LPS) medium was statistically higher (P < 0.05) for the GT+P group than for the GTB or antibiotic group. IL-6 and TNF-α production by spleen cells induced by Con A and LPS was increased in the GTB and GT+P group (P < 0.05) compared with the antibiotic group. Taken together, the results of the present study indicated that GT+P exerts positive effects on weight gain, meat composition, blood parameters and immunity in pigs, and could be used as an alternative to antibiotics for growing–finishing pig feeds.

The present study aimed to investigate the effects of dietary supplementation with powdered peanut skin (PS) as natural antioxidant and growth promoter on growth performance, carcass characteristics, serum metabolites and meat quality of Cobb broiler chickens. A total of 240 unsexed Cobb 500 1-week-old broiler chicks were randomly assigned to four treatment groups with six replicates. The dietary treatments consisted of the basal diet as control and PS groups (1.0, 2.0, and 3.0 PS g/kg). Results showed that the highest values (P < 0.01) of live bodyweight and bodyweight gain were observed in the control group at 3 weeks of age and during the period of 1–3 weeks of age, respectively compared with all levels of PS. During 1–3 weeks of age, feed intake per day chicks fed the diet containing PS levels decreased numerically (P > 0.01) with increased levels of PS compared with the control. Supplementing 1.0 or 3.0 g/kg of PS insignificantly enhanced feed conversion ratio at 1–6 weeks of age. Dietary treatments significantly depressed giblets (P = 0.002), thigh (P = 0.0.027) and abdominal fat percentages (P > 0.0.1), however, increased (P = 0.004) breast percentage of broiler chicks at 6 weeks of age. The lowest value of serum creatinine and urea achieved by chicks fed diet contained 3.0 PS g/kg diet. Also, high density lipoprotein cholesterol in addition to triglycerides were significantly (P < 0.05 and P < 0.01) decreased with increasing level of PS supplementation. It can be concluded that PS as a phytogenic additive could be used as a supplementation to broiler diets to lower abdominal fat in carcass and cholesterol, creatinin and urea in blood. Sensory characteristics were not affected except that appearance was improved. Water-holding capacity was also improved.

The main objective of the investigation was to observe the growth performance, carcass yield, meat quality, and intestinal morphology of broiler chicks with respect to the dietary crude palm stearin (CPS). The study was conducted on 200 birds and dividing them into two experimental groups viz control and CPS treated group with 10 replications of 10 birds in each. Chicks under the control group were fed basal diet only, however in CPS treated group chicks were fed the basal diet supplemented with 3% CPS. Birds were reared for 42 days and data regarding different parameters of study was recorded. Data were analyzed by student T-test and differences were considered significant at P < 0.05.Results indicated CPS treated group pertaining to lower final body weight, daily weight gain, feed conversion ratio, feed intake, dressing percentage, fillets, thight+drumsticks, and wings percentages. CPS treated group possessed lower liver, spleen, gizzard, and abdominal fat weights. Breast meat holds lower values for shear force, drip loss in CPS treated group, while cooking loss found vice versa. Abdominal fat breast in the meat and thigh skin possessed higher a* (redness) and b* (yellowness) values in CPS treated chicks, while breast skin and thigh meat hold lower a* and b* values in CPS treated chicks compared to control. Intestinal villus height, villus area and crypts depth in duodenum found considerably higher in the CPS treated chicks. Jejunum in CPS treated group possessed higher crypt depth but villus height and villus area remained lower. In conclusion, CPS impairs overall growth performance, carcass yield and meat quality but supports the intestinal morphology.

Background: The present study investigated the effects of different levels of Acanthophyllum bracteatum powder (ABP) on growth performance, carcass parts yield, blood serum indices, and meat quality in Ross 308 broilers. Methods: A total of 240 one-day-old male broilers were allocated into six dietary treatments, with 4 replicate pens and 10 birds per each pen. Six levels of supplemental ABP, at 0 (control), 0.5, 1.0, 1.5, 2.0 and 2.5 g/kg of the basal diet, were randomly combined to different experimental units, randomly. Results: The findings indicated that the average daily gain (ADG) and feed conversion ratio (FCR) were affected by supplementation of ABP at 2.0 and 2.5 g/kg (p < 0.05) in the whole experimental periods. However, average daily feed intake (ADFI) was not affected by the dietary treatments (p > 0.05). It was also observed that the relative weight of abdominal fat decreased significantly by 2.0 g/kg ABP as compared to the control group (p = 0.038). Supplementation of ABP at 1.5, 2.0 and 2.5 g/kg decreased the total blood serum cholesterol (CHOL) and thiobarbituric acid reacting substances (TBARS), as compared to the control group, significantly (p < 0.05). Conclusion: It can be concluded that incorporation of ABP into the diet, as a medicinal plant source, at 2.0 or 2.5 g/kg, might have some desirable effects on the productive performance, ileal microbiota, CHOL concentration and relative weight of the abdominal fat of broiler chickens.

Inulin is one of the commercially feasible dietary fibers that has been implicated in regulating the gut health and metabolism of animals. This experiment was conducted to investigate the effect of dietary inulin supplementation on growth performance and meat quality in growing–finishing pigs. Thirty-six Duroc × Landrace × Yorkshire White growing barrows (22.0 ± 1.0 kg) were randomly allocated to two dietary treatments consisting of a basal control diet (CON) or basal diet supplemented with 0.5% inulin (INU). Results showed that inulin supplementation tended to increase the average daily gain (ADG) at the fattening stage (0.05 < p < 0.10). Inulin significantly increased the dressing percentage (p < 0.05) and tended to increase the loin-eye area. The serum concentrations of insulin and IGF-I were significantly higher (p < 0.05) in the INU group than in the CON group. Moreover, inulin supplementation significantly elevated the expression level of myosin heavy chain II b (MyHC IIb) in the longissimus dorsi (p < 0.05). Inulin significantly upregulated the expression of mammalian rapamycin target protein (mTOR) but decreased (p < 0.05) the expression level of muscle-specific ubiquitin ligase MuRF-1. These results show the beneficial effect of inulin supplementation on the growth performance and carcass traits in growing–finishing pigs, and will also facilitate the application of inulin in swine production.

The current research aimed to evaluate the effects of dietary inclusion of wood vinegar on growth performance, nutrient digestibility, and meat quality of grower-finisher pigs. In total, 132 crossbred ({Landrace × Yorkshire × Duroc}) grower-finisher pigs with an initial average body weight 30.48±4.23 kg (11 replications/treatment; 4 pigs/pen) were used in a 16-week trial. Based on the body weight and sex the pigs were randomly assigned to three treatments. Dietary treatments consisted of the basal diet (CON) or the basal diet supplemented with 0.05% and 0.1% wood vinegar. The inclusion of dietary wood vinegar supplementation significantly improved the body weight gain (BWG) and average daily gain (ADG) (P=0.0521; 0.043) of pigs at week 16. The total track nutrient digestibility of dry matter and nitrogen was linearly increased in pigs fed with an increased amount of wood vinegar. In addition, dietary supplementation of wood vinegar linearly improved longissimus muscle area, yellowness (b*) of the meat color, and carcass weight (P<0.05) and a tendency in linear reduction was observed for water holding capacity (P=0.068), and drip loss at d5 and d7 (P=0.091, 0.069). However, there was no significant difference found for lean meat percentage and backfat thickness in this experiment. In summary, dietary inclusion of wood vinegar supplementation enhanced growth performance and total track digestibility of nutrients and had no effects on lean meat percentage and backfat thickness of grower-finisher pigs.

AbstractThe aim of this study was to determine whether dietary supplementation with zinc oxide nanoparticales (NP-ZnO) as a substitute for the conventional ZnO affects the intestinal digestibility of selected minerals, growth performance and meat quality in turkeys. The replacement of ZnO with NP-ZnO had no effect on the intestinal digestibility of Zn, Cu, Fe and Ca, whereas the lowest dose of supplemental Zn reduced Zn digestibility. The applied inclusion levels and sources of Zn had no effect on the growth performance (except the feed intake) of turkeys, including liveability. No differences in the relative weights of the heart, spleen and bursa of Fabricius (except the liver), or the weights of the femur and tibia were found between the dietary treatments. Neither the dose nor the source of supplemental Zn influenced carcass dressing percentage or the share of breast, thigh and drumstick muscles in the carcass. In comparison with the highest and moderate doses of Zn, the lowest inclusion level of Zn contributed to increased yellowness of breast meat (P=0.005). The analyzed doses and sources of supplemental Zn exerted varied effects on the redox status of fresh and frozen breast meat. In conclusion, the growth performance of turkeys, carcass yield and composition as well as the redox status of fresh and frozen breast meat were generally similar, regardless of the dietary source and level of Zn. The beneficial effect of Zn addition at 100 mg/kg was improved Zn and Ca digestibility, and increased redness of breast meat.

The supplementation of rumen bypass fat (RBF) has remained one of the preferred approaches used to decrease undesirable saturated fatty acids (FA) and increase beneficial unsaturated FA in the meat. This study was planned to evaluate the influences of rumen bypass fats on meat quality, fatty acid and metabolic profiles in male Dorper sheep (n = 36) with 24.66 ± 0.76 kg (mean ± standard error) initial body weight. Treatment comprised a basal diet (30:70 rice straw to concentrate) with no added RBF as a control (CON), basal diet with prilled fat (PF), basal diet with prilled fat plus lecithin (PFL) and basal diet with calcium soap of palm fatty acids (CaS). The findings revealed that cooking loss, drip loss and shear force in longissimus dorsi (LD) muscle were not affected by RBF supplementation, while meat pH was significantly higher in the CaS on aging day 1. However, the diet supplemented with prilled fat and lecithin modified the meat’s fatty acid profile significantly by increasing unsaturated fatty acids and decreasing saturated fats. The relative quantification of the major differentiating metabolites found in LD muscle of sheep showed that total cholesterol, esterified cholesterol, choline, glycerophosphocholine and glycerophospholipids were significantly lower in CaS and PFL diets, while glycerol and sphingomyelin were significantly higher in CaS and PFL diets. Most of the metabolites in the liver did not show any significant difference. Based on our results, the supplementation of protected fats did not have a negative influence on meat quality and the meat from Dorper sheep fed prilled fat with lecithin contained more healthy fatty acids compared to other diets.

The experiment aimed to investigate the effects of dietary β-mannanase supplementation on growth performance, apparent total tract digestibility (ATTD) of nutrients, intestinal integrity, and the immunological and oxidative stress parameters in weaning pigs. A total of 64 newly weaning pigs (initial body weight: 6.96 ± 0.70 kg) were allotted to two dietary treatments in eight replicates per treatment with four pigs per pen based on body weight and sex. Dietary treatments were 1.) CON (control: corn-soybean meal based basal diet) and 2.) β-mannanase (basal diet +0.06% β-mannanase). The β-mannanase supplementation did not affect growth performance, concentrations of acute phase protein, superoxide dismutase and glutathione peroxidase. However, the pigs fed the β-mannanase-supplemented diet had greater ATTD of ether extract, jejunum villus height, and villus height-to-crypt depth ratio, and lower crypt depth compared with those fed the CON diet (p < 0.05). The pigs fed the β-mannanase-supplemented diet tended to have the lower count of E. coli in cecum than those fed the CON diet (p = 0.08). In conclusion, dietary β-mannanase supplementation did not affect growth performance, immune response and oxidative stress of weaning pigs, whereas it increased fat digestibility and had positive effects on intestinal integrity and cecum microflora by reducing the count of E.coli.
