A feeding trial was conducted to investigate the effects of Piper sarmentosum leaves (PSL) on meat quality of broilers. The 144 commercial broiler chicks, one day old, were randomly assigned to 5 groups with three replicate cages. The five treatments were: 1) basal feed (8 chicks/cage), 2) basal feed (10 chicks/cage), 3) basal feed supplemented with 1% of PSL (10 chicks/cage), 4) basal feed supplemented with 2% of PSL (10 chicks/cage), and 5) basal feed supplemented with 3% of PSL (10 chicks/cage). The duration of dietary treatments was 42 days. The results showed that the group supplemented with 3% PSL had higher redness, yellowness, and cooking loss than the control group with 10 chickens/cage (P less than 0.05). It was also observed that the 3% PSL treatment gave significantly lower lightness than the 0% and 1% PSL treatments with 10 chickens/cage (P less than 0.05). Overall, the study indicated that PSL might improve chicken meat colour and protect against protein oxidation, but it has no potential in protecting against lipid oxidation in broiler filet.

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.

An experiment was conducted with 60 day old Cobb-500 broiler chicks for a period of 28 days with the aims of investigating the effects of different level of garlic powder on growth performance, carcass characteristics and meat quality of broilers to produce safe broiler meat. The experimental broiler chicks were divided randomly into four different groups with three replications having 5 chicks in each. Maize-soybean based diet was used as basal diet for group 1. Basal diet was supplemented with 1%, 2% and 3% garlic powder on fresh basis for group 2, 3, and 4 respectively. The broiler of groups 2, 3, and 4 were showed significantly (p>0.05) higher body weight than control group at 4 weeks of age. Feed conversion ratio of group 2, 3, and 4 were significantly (p>0.05) lower than group 1. Group 2 was given significantly lower fat percentage than other groups. Group 3 and 4 showed more or less similar fat content but lower than control groups. Thus, it may be concluded that garlic powder may be used in chicken diet.Bang. J. Anim. Sci. 2016. 45 (2): 79-83

This study aimed at examining the effects of curcumin supplementation on growth performance, antioxidant capacity, and meat quality of ducks. To investigate these effects, 600 healthy ducks were randomly assigned to four treatment groups with 10 replicates pens, and each pen contained 15 ducks. Ducks were fed a diet containing curcumin at levels of 0, 300, 400, and 500 mg kg−1 in different groups. The results demonstrated that curcumin supplementation is beneficial to the growth performance (p < 0.05) of ducks and antioxidant capacity (p < 0.05) of duck meat. In addition, dietary curcumin raised the meat quality of ducks, improving the meat color, increasing water-holding capacity, and inhibiting lipid and protein oxidation. In conclusion, the present study provides important insights into both the nutrient and qualities of ducks, finding that a dietary inclusion of 400–500 mg/kg of curcumin (kg−1) has the greatest effect.

AbstractA feeding trial was conducted to evaluate the effects of plant extracts derived from Mentha arvensis (MA) and Geranium thunbergii (GT) on broiler performance, carcass yield, digestive organ weights, meat quality and odorous gas emissions from the excreta. A total of 210 one-day-old broiler chicks were randomly assigned to one of the following dietary treatments for five weeks: (1) control, (2) 0.1% MA, (3) 0.05% GT, (4) 0.1% GT and 0.1% mixed preparation with varying ratios such as (5) 0.1% 1MA:1GT, (6) 0.1% 1MA:4GT and (7) 0.1% 4MA:1GT. The weight gain (0–3 weeks) was significantly (P<0.01) increased in response to dietary inclusion of plant extracts; however, no significant differences were observed in breast and thigh meat yield (P>0.05). Additionally, no differences were observed in proventriculus, gizzard, pancreas, small and large intestine weight. When compared with the control group, birds fed plant extracts had the lowest meat TBARS value after 0 and 3 weeks of storage (P<0.05). Moreover, the pH value was significantly lower (P<0.05) in the plant extract supplemented groups at 0 weeks. The faecal H2S emissions were significantly reduced at 0 h and 6 h in all supplemented groups relative to the control (P<0.05). Similarly, NH3 emissions were reduced at 0 h and 6 h for all supplemented groups except the 0.1% 1MA:1GT group (P<0.05). Overall, the results of the present study indicate that plant extracts supplementation can be used to improve performance and meat quality of broiler chickens while reducing the emission of harmful gases from the excreta.

An experiment was conducted to determine the effects of supplementing the diet of Jinjiang bulls with guanidinoacetic acid (GAA) on their feed efficiency [feed efficiency were evaluated with feedlot average daily gain (ADG), average daily feed intake (ADFI), and feed-to-gain ratio (F:G)], blood measures, and meat quality. Forty-five Jinjiang bulls (24 ± 3 months old and 350.15 ± 30.39 kg by weight) were randomly distributed among five experimental groups (each n = 9) and each group was randomly fed with one of five diets (concentrate: roughage ratio of 60:40): (1) control; (2) 0.05% GAA; (3) 0.1% GAA; (4) 0.2% GAA; and (5) 0.4% GAA, respectively. After a 52-days feeding trial, five bulls from the control group and five bulls from the optimal GAA supplementing group were randomly selected and slaughtered for collection of the longissimus thoracis (LT) and semitendinosus (SM) muscles to determine meat quality. The results showed that dietary GAA improved the ADG, decreased the value of F:G, and affected blood measures and antioxidant variables. Supplementing 0.2% GAA into the diet was optimal for feeding efficiency and most of the measured blood measures. Supplementing 0.2% GAA into the diet increased the a* (redness) values, and b* (yellowness) values, and the amount of creatine kinase (CK), muscle glycogen, creatinine (CRE), and laminin (LN) in LT muscles. However, it decreased the drip loss, L* (lightness) value, and lactate dehydrogenase (LDH) content of LT muscles. Drip loss and shear force decreased in SM muscles, as did the amount of type IV collagen (CV–IV). In conclusion, supplementing 0.2% GAA into the diet could enhance feed efficiency to improve beef growth and meat quality.

A feeding trial was conducted to investigate the effect of Probiotic (Biofast) on the growth performance and meat quality of broiler chicken. Ninety six 1-d-old mix sexed Cobb 500 broiler chicks were obtained from a local commercial hatchery. Chicks were randomly allocated in 2 experimental treatments for 5 wk. The experimental treatments received a 1) control, 2) control with probiotic Biofast 0.055% (bacillus subtilis-100%) in the diet. Both treatments had 48 broilers arranged in 4 replicates of 12 broilers each. Eight birds from 2 different groups (one/replication) were sacrificed on termination of the feeding trial of breast, thigh to investigate the meat quality. Feed intake in treatment T1 was significantly (P > 0.05) greater than control in 0 to 3 weeks of age. Though in starter phase treatments failed to induce any marked effects on body weight, weight gain and FCR but numerically increased in T1 than control. In finisher period (4-5 wks), there were no significant differences on body weight, weight gain, feed intake and FCR between the treatments. The organ weight like liver, heart, kidney, spleen, gizzard, abdominal fat and intestine weight also did not show any significant differences between the dietary treatments of control and Biofast. In addition, though the dressing % was not significantly different but numerically higher percentage was found by using Biofast. Similarly, no significant differences (p>0.05) were found in pH, cooking loss, meat color and TBA values between the treatments. In conclusion, supplementation of Biofast in diet has no significant effect on the growth performance of broiler chicks though it has got some positive effects on other parameters that indirectly revealed to enhance meat quality of broiler chicken as well as food safety issues.

The objective of the study was to determine the effects of probiotic bacteria Bacillus licheniformis and Bacillus subtilis on microbiological properties of feed mixtures and on the digestive tract content as applicable to production traits and carcass characteristics of fatteners. The experiment was performed on 83,838 fatteners from four successive (insertions) productions in two groups. From the seventy eighth day of age till marketing to the slaughter plant, the pigs were supplied with BioPlus YC probiotic (Chr. Hansen) in the amount of 400 g/t. The preparation contained a complex of probiotic bacteria Bacillus licheniformis DSM 5749, and Bacillus subtilis DSM 5750 spores in a 1:1 ratio. From the fourth insertion, after reaching a body weight of approximately 112 kg, 60 fatteners were selected from each group to measure carcass quality and half of them for meat quality evaluation. Moreover, microbiological analyses in feed and colon were performed. The study showed that BioPlus YC probiotics supplementation resulted in a significantly higher count of B. subtilis and B. licheniformis in the feed, a higher count of B. subtilis, B. licheniformis and LAB, as well as a lower count of Enterobacteriaceae, Enterococcus, Clostridium and Bacillus sp. in the mucosa and in the colorectal content of the test pigs. Our work has shown that supplementation with the BioPlus YC probiotic had a positive effect on the production traits of pigs mainly by reducing mortality (2.83%, p = 0.010), lowering feed conversion ratio—FCR (2.59 kg/kg, p = 0.013), better average daily gain—ADG (0.95 kg/day, p = 0.002) and shorter fattening period (77.25 days, p = 0.019) when compared to the control group (4.19%; 2.79 kg/kg; 0.89 kg/day; 92.8 days, respectively). The addition of the specific Bacillus bacteria did not influence carcass and meat characteristics of the test fatteners.

There is a growing demand by the modern consumer for meat containing less fat and lower levels of saturated fatty acids, which are considered to increase the risk of coronary heart disease. In southern Italy, the Gentile di Puglia breed is one of the most common on farms, and the light lambs are often consumed. The study evaluates the effect of a diet containing extruded linseed (Linum usitatissimum) on growth performances, carcass traits, and meat quality in Gentile di Puglia light lambs. Thirty-six male lambs are weaned at about 20 days of age, and divided into three groups—each group is either fed a control diet (C), a diet containing 3% extruded linseed (L), or a diet containing 3% extruded linseed and 0.6% oregano (Origanum vulgare) (L + O). The lambs’ growth performances and the slaughtering and dissection data did not differ between groups. Dietary treatments have no significant effect on the quality and chemical composition of Longissimus lumborum (Ll). The mount of linoleic acid in Ll meat is significantly higher in the L group, and this positively affected the total content of n-3 Polyunsaturated Fatty Acid, as well as the n-6/n-3 ratio. The good results obtained concerning the sensory traits meet the requirements of the market’s consumer.

This study was undertaken to investigate the growth performance and immune responses of broiler chicks fed diets supplemented with conjugated linoleic acid (CLA). Two hundred and forty day-old Arbor Acre male broiler chicks were randomly allotted into four dietary treatments with different inclusion levels of CLA (0, 2·5, 5·0 or 10·0g pure CLA/kg) for 6 weeks. Growth performance, lysozyme activity, peripheral blood mononuclear cell (PBMC) proliferation, prostaglandin E2 (PGE2) synthesis and antibody production were investigated. There were no significant differences in growth performance among treatments (P>0·05). Chicks fed 10·0g CLA/kg diet produced 40% and 49% more lysozyme activity in serum and spleen than the control group at 21d of age (P<0·05). Dietary CLA enhanced the PBMC proliferation in response to concanavalin A at the age of 21 and 42d (P<0·05). Systemic and peripheral blood lymphocytic synthesis of PGE2 in chicks fed 10·0g CLA/kg diet was significantly decreased by 57% and 42% compared to chicks fed control diet (P<0·05). Antibody production to sheep red blood cell and bovine serum albumin were elevated in either 2·5 or 10·0g CLA/kg dietary treatments (P<0·05). The results indicated dietary CLA could enhance the immune response in broiler chicks, but did not alter the growth performance.
