“…As reported above, the main actions of PAs are their antimicrobial and anticoccidial activities, and enhancement of nutrient digestibility and broiler performance. The results obtained with PAs relative to carcass and parts yields in the present study are in agreement with other experiments (García et al, 2007;Sheuermann et al, 2009) that did not find any influence of the dietary addition of PAs on these parameters.…”

The objective of this study was to evaluate the effect of the dietary supplementation of phytogenic additives (PAs) and glutamine plus glutamic acid (Gln/Glu), associated or not, in replacement of antibiotic growth promoters and anticoccidials (AGP/AC) on the performance and carcass yield of broilers. Five hundred male Cobb broilers were housed in an experimental house and randomly distributed into five treatments, with four replicates of 25 birds each. Treatments consisted of a control diet (CD); CD+AGP/AC; CD+Gln/Glu; CD+PAs; CD+Gln/ Glu+PAs. Diets were formulated only with plant feedstuffs, i.e., they did not contain any animal byproducts. Performance data were collected for the accumulated periods of 1-7, 1-21, and 1-42 days of age. Carcass yield and parts yield were determined at 42 days of age. Treatments did not influence performance during none of the evaluated periods. The greatest carcass yield (p<0.05) was obtained in birds in the treatments CD+Gln/Glu and CD+Gln/Glu+PAs relative to CD, but not different from birds in the AGP+AC and PAs treatments, which were not different from the CD treatment. Birds fed the CD+Gln/Glu diet presented greater breast yield (p<0.05) compared with those in the CD and AGP/AC treatments, but there was no difference in comparison with the other treatments. Under the conditions of the present experiment, the dietary supplementation with phytogenic additives and with glutamine plus glutamic acid does not affect the performance, but improves carcass yield and breast yield of broilers.

“…Considering other carcass traits, according to the data given in Table 6, the results of this study (maintaining the inefficacy of added S. hortensis essential oil and commercial drug Orego-Stim in male broiler diet regarding the yielded carcass and relative weights of the heart, bowel, breast and thigh as compared to the weight of the live tested chickens), were in conformity with the results reported by Pish Jang (2011) reporting no impacts on the relative weights of gizzard and heart, Kirkpinar et al (2011) showing no improvements in carcass and relative weight of gizzard, small intestine and heart, Vukic-Vranjes et al (2013) maintaining no positive effects in breast and thigh, Scheuermann et al (2009) showing no significant difference in carcass composition, Nobakht et al (2011) revealing insignificant effects on thigh, gizzard and intestine weight, Ghalamkari et al (2011) stating no influences on the weight of internal organs and carcass characteristics, Jang et al (2007) indicating lowers firm-level which did not affect the weight of the intestine, Hernandez et al (2004) mentioning no relevant effects on the weight of the gizzard and intestines, Khaligh et al (2011) declaring no significant improvements in the characteristics of carcass and even loss of yielded carcass, and finally Lee et al (2003) who concluded that lower firm-level had no effect on carcass composition of broiler chickens fed with herbal additives. However, the findings of the present study were not in agreement with the studies carried out by Pooryousef and Hosseini (2011) who showed an increase in the relative weight of the breasts and improved indicators of carcass traits, Jamroz et al (2005) reporting 1.2% weight increase when comparing the breast muscle weight to body weight, Khodaei (2011a) showing increases in relative weight of the breast muscle, and Hosseini 2011concluding improved breast weight and carcass traits in broilers fed with herbal additives.…”

This experiment was carried out to study the effects of dietary supplementation of Satureja hortensis essential oil on growth, carcass parts, pH and luminal microbe in broiler chicken. A total of 400 one week old ROS 308 male chicks were used in a completely randomize design model with 5 treatments and 4 replicates, each composing of 20 chicks. Duration of experiment was 35 days until the age of 42 days. Treatments were a basal diet supplemented with 50, 100 and 150 mg/kg of S. hortensis essential oil with a negative (no supplementation) and a positive control (containing 300 g/1000 kg) of Orego-Stim (a commercial compound). Feed intake and body weight gain were measured weekly and feed conversion ratio was calculated accordingly. Chicks were reared on litter and were fed ad libitum with antibiotic and coccidiostat free diet. At 35 th day, litter samples was collected and sent to laboratory for determining its moisture and bacterial total count. At the 42 nd day, two chicks per cage were slaughtered for determining carcass parts ratio, ileum digesta pH and bacterial count by dilution method. Results showed that S. hortensis essential oil and Orego-Stim compound had no effects on broiler growth. Liver relative weight increased by 50 and 150 ppm S. hortensis essential oil as compared to the control group. No change of pH was observed due to treatments. Chicks that received 150 ppm S. hortensis essential oil showed higher litter bacterial count as compared to the control and other treatments.

“…In terms of profit, net profit and net profit (live broiler) were significantly (P<0.05) differed among the treatment group. Increased profit was observed both in phytogenic feed additive and prebiotic supplemented groups comparing to the control group and this result is similar with Scheuermann et al (2009). Other researchers (Samarasinghe et al, 2003;Parks et al, 2001) found that growth performance improve by the use of prebiotic in broiler ration.…”

This study was conducted to determine the effect of phytogenic feed additive and prebiotic on vegetable protein base diet in broiler performance. A total of 90 chicks (Cobb-500) were weighted and randomly assigned to the three treatment groups (T o , T 1 and T 2 ) and supplemented with either phytogenic feed additives or prebiotic and reared for 28 days. Data on live body weight, body weight gain, feed intake and feed conversion (FC) were taken at weekly interval. Results revealed that significant (P<0.05) increase in live body weight of broilers was evident in both phytogenic feed additive and prebiotic supplemented groups comparing to the control group at 4 th weeks of age. No significant (P>0.05) differences were found in live weight gain among the treatment groups on weekly intervals along the whole experimental period. However, significant differences (P<0.05) were evident on cumulative weight gain at 3 rd and 4 th weeks of age. In case of feed intake at the age of 3 rd and 4 th weeks, significant (P<0.05) differences were obtained with decreased feed intake in both phytogenic feed additive and prebiotic supplemented groups comparing to the control group. In case of feed conversion (FC), there were significant (P<0.05) differences among the groups on 1 st week and 4 th week of age. Best FC was accounted for prebiotic supplemented group along the whole experimental period. The survivability rates were 96.67%, 100% and 100% in control group, phytogenic feed additive and prebiotic supplemented group respectively. Results finally showed that vegetable protein when supplemented with phytogenic prebiotic feed additives and prebiotic c an additive beneficial effect on performance of when compared to non-supplemented control diet. So, ration using vegetable protein mixed with phytogenic feed additives or prebiotic can be recommended for broiler.
