“…The highest carcass yield was found in the CAP group, while the lowest was found in the CAR and control groups (p<0.05). The findings of the study were found to agree with those of Alcicek et al (2004), Simsek et al (2005), Shanoon et al (2012), Duarte et al (2013), Khattak et al (2014) and Kirkpinar et al (2014). Additionally Babaoglan and Kutlu (2008) reported that addition of thymol:carvacrol (1:1) did not affect the carcass yield, but reduced the abdominal fat ratio.…”

The aim of this study was to evaluate the effects of dietary capsicum oleoresin (CAP, 150 mg/kg), carvacrol (CAR, 150 mg/kg), cinnamaldehyde (CIN, 150 mg/kg) and equal amount of mixtures (CAP+CAR+CIN, 50 mg/kg each, capsicum oleoresin + carvacrol + cinnamaldehyde) supplements on growth performance, carcass characteristics, intestinal microflora, some blood parameters and IGF1 gene expression levels in broiler chickens. In the experiment, four hundred Ross-308 day-old, both sexs broiler chicks were randomly distributed to five dietary treatments, each with five replicates. Among these five dietary treatment groups formed for the experiment, the control group was fed without feed additives (control), the second group with 150 mg capsicum oleoresin for each kg of feed, the third group with 150 mg carvacrol for each kg of feed, the fourth group with 150 mg cinnamaldehyde for each kg of feed, and the last group with 150 mg mixtures for each kg of feed. The experiment was maintained to six weeks. According to the research results, the effects of dietary treatments on the body weight and the body weight gain were found to be significant (p<0.05). Especially in the group fed on diet added CAP+CAR+CIN, the treatments had a significant effect on feed intake and feed conversion ratio as well as body weight and body weight gain when compared to the control group on a periodic basis (p<0.05). In addition, the effect of the treatments on livability is insignificant (p>0.05). Among carcass properties, only carcass yield and some organ-related properties were significantly affected from addition of capsicum oleoresin, carvacrol, cinnamaldehyde and their mixtures (p<0.05). Cinnamaldehyde and mixture groups caused to significantly (p<0.05) reduce AST levels, carvacrol, cinnamaldehyde and capsicum oleoresin groups led to decrease level of triglycerides, carvacrol and mixture groups importantly (p<0.05) affected LDL levels were detected. And also, especially in the mixture groups, the number of ileum Lactobacillus spp. was found to be significantly higher (p<0.05) than the other groups. The changes in dietary content were not accompanied by changes in IGF-1 gene expression levels (p>0.05). In conclusion, the supplementation carvacrol, cinnamaldehyde, capsicum oleoresin and especially their mixtures at the level of 150 mg/kg to broiler diets affected positively growth performance, slaughter characteristics, some examined intestinal microflora and blood parameters in broiler chickens.

“…Kavouridou et al [ 46 ] reported that 10% coconut, palm or flax seed oil extraction were not effective on the chemical composition of broiler chick and so did Fotea et al [ 47 ] for additions of 0.1, 0.3 and 0.7% thyme oil extraction; and Kirkpinar et al [ 37 ] for the additions of 300 mg thyme, garlic, thyme+garlic. Duarte et al [ 48 ] associated the ineffectiveness of 3.3, 6.6 and 9.9% of corn oil additions on CF of the chicken meat with the level of energy intake; and claimed that it could be due to the fact that the energy value of the feed had not changed.…”

BackgroundIn recent years, with the prohibition of antibiotics used as growth stimulants in the nutrition of farm animals, researchers have searched for alternative natural and reliable products in order to be able to sustain the developments experienced during the use of antibiotics and to overcome the possible inconveniences. In this context, studies on evaluation of essential oils in poultry nutrition have been reported to improve the utilization of feed, stimulate the release of digestive enzymes, increase absorption in the stomach and intestines, antimicrobial and anti-parasitic effects and thus, can be an alternative to antibiotics and improve meat quality as well. Indeed, this study has been carried out to explore the effects of the addition of 150 mg/kg capsicum oleoresin (CAP), carvacrol (CAR), cinnamaldehyde (CIN) or their mixture (CAP+CAR+CIN) into the broilers’ ration over sensory, physical and chemical properties in breast meat and leg meat.MethodsExperiments were conducted over 400 male and female broiler chicks (Ross-308) in 5 groups (1 control group and 4 treatment groups), each composed of 80 chicks. The control group was fed without feed additives while the second, third, fourth and the fifth groups were fed with 150 mg CAP/kg feed, 150 mg CAR/kg feed, 150 mg CIN/kg feed, and 150 mg CAP+CAR+CIN/kg feed, respectively.ResultsAddition of CAP, CAR, CIN or CAP+CAR+CIN had effects on the sensory (of taste, tenderness, juiciness and overall acceptability); physical properties (of L* value and toughness), the chemical properties (of DM, CF, CP, linoleic, EPA, behenic, MUFA, PUFA and ∑n-6 of the leg meat), the physical characteristics (of toughness and firmness), and the chemical properties (of CF, CP, linoleic, ecosenic, EPA, lignoseric, MUFA and ∑n-3) of the breast meat in comparison to control group. Furthermore, while the treatments had positive impacts on thawing loss, cooking loss and water holding capacity in both breast and leg meat; no effect was observed on pH value and lipid oxidation on day 1, day 4 and day 8.ConclusionThe results strongly suggested that the addition of CAP, CAR, CIN or CAP+CAR+CIN to the rations of the broiler chicks changed the sensory, physical and chemical properties of breast and leg meat. It was also observed that these compounds were more effective when they were added to the ratio as a mixture rather than adding them individually.

“…A preliminary study (Waldroup et al 1990) found no effect of energy concentration of diets on growth performance or abdominal fat, although higher energy density increased dressing percentage in females, but not in males. Similarly, others found no effect of dietary energy level on carcass yield or abdominal fat (Nunes et al 2012; Duarte et al 2014). In contrast, Marcu et al (2012a) reported improved growth performance and carcass yield for the main cuts of broiler chickens fed diets with high energy and protein levels.…”

Background Diets with increasing levels of energy were fed for 42 days to 200, 1-day old male broiler chickens to evaluate growth performance, carcass characteristics and chemical composition of meat. The study was performed in the subtropical area of northeastern Mexico. Treatments diets (T) for starter and finisher phases had apparent metabolizable energy (AME; kcal/kg) of: 2960 and 3040 (T1); 3000 and 3080 (T2); 3040 and 3120 (T3); 3080 and 3160 (T4), respectively. Within each of the growing phases the four treatment diets were formulated to contain similar levels of crude protein, amino acids, and other nutrients. In a completely randomized design, birds were allocated to the four treatments with five replicates (floor pens) of 10 birds each. The trial was divided in two phases (starter and finisher) of 21 days each (42 days total).ResultsWeight gain was not influenced by energy level; however, feed conversion efficiency was improved in the diets with 3040 and 3120 kcal/kg AME (T3; P < 0.05). There was no influence of treatment on total carcass weight or carcass cuts (P > 0.05). Meat from breast muscle had similar crude protein percentages among treatments; ether extract was higher in T1 than T4 (P < 0.05). The percentages of water, ether extract, ash and crude protein in thigh meat were not significantly different (P > 0.05) among treatments. ConclusionsFor this study carried out in a dry tropical area, the moderate increase in dietary energy concentration (diet with 3040 and 3120 kcal/kg AME, T3) enhanced feed conversion efficiency of broiler chickens.
