“…Cross et al (2007) also observed no differences in DMMC and GEMC when assessing the metabolizability influence of different plant extracts. However, the mixture of active principles in the PA of the present study may have shown increased enzyme activity, which promoted improved nutrient metabolizability.…”

-The experiment evaluated the influence of isolated or associated phytogenic additives (PA) and organic acids (OA) on nutrient digestibility, performance and carcass characteristics of broiler chickens. Two experiments were conducted in a completely randomized design with a 2 × 2 + 1 factorial arrangement of treatments (with or without PA × with or without OA + antibiotic performance enhancer and anticoccidial). In the first experiment, two metabolic tests were conducted to determine the metabolizability coefficients of the nutrients of starter and growth diets. In the second experiment, 2520 one-day-old chicks were housed in 40 experimental units to evaluate the performance and carcass characteristics. The phytogenic additives and organic acids, isolated or associated, improve the nutrient digestibility of the diet and replace the growth-promoting antibiotics. The use of organic acids isolated or associated with phytogenic additives in broiler diets improves broiler performance in comparison with free antibiotic performance enhancer at 42 days of age. Isolated or associated phytogenic additives and organic acids provided better carcass characteristics.

-93 - Acta fytotechn. zootechn., 17, 2014( IntroductionPhytogenic feed additives are used in animal nutrition and feeding for their beneficial effects such as higher performance, reproduction and health status (Capcarová and Kolesárová, 2010). Phytogenics are feed additives, plant-derived products used in animal feeding to improve the performance of livestock. Most studies investigate blends of various active compounds and report the effects on production performance rather than the physiological effects (Windisch et al., 2008). The last two decades have seen a substantial increase in the use of aromatic herbs and essential oils as feed additives in animal nutrition (Franz et al., 2010). Positive effect of phytoadditives are determine by application dosage and additive composition (Gálik et al., 2013), they are usable in animal nutrition for better feed conversion ratio and nutrient utilization (Kroismayr et al., 2007 andLi et al., 2007). In laying hens nutrition, feed additives can improve their production and also nutrient composition of eggs, mainly yolk nutrients content. The aim of the study was to analyse the dietary effect of Rhus coriaria L. seeds as a phytogenic additive on yolk nutrient composition in Hy-Line Brown laying hens nutrition. Material and MethodsThe experiment was realised in cooperation with the Department of Poultry Science and Small Animal Husbandry. Trial lasted 21 weeks. Hy-Line Brown laying hens were used for the trial. At 20 week of age, total 20 hens were randomly divided to two group, control group (C) and experimental group (E), in each group 10 hens. Hens in both groups were fed by standard feed mixture contained 39. Results and DiscussionThere are many papers, which focused on different feed additives for poultry as an alternative for antibiotic growth promoters (Cross et al., 2007;Gálik et al., 2013). Plant extracts, or their ethereal oils are typical for many desirable effects, such as inhibition of pathogen microorganism and stimulation of same desirable physiological processes (Gali-Muhtasib et al., 2006;Yazan et al., 2009). In our experiment we analyzed the effect of a phytogenic additive Rhus coriaria L. on yolk nutrient composition during 21 weeks. During the trial, the eggs were analysed three times, every 7 weeks after the experiment start. Results are show in Table 2. We found insignificant (P >0.05) differences in dry matter content in egg´s yolks. In crude protein of egg´s yolk in 1 st and 2 nd collection we found a tendency (P >0.05) of higher content in eggs of hens fed with Rhus coriaria L. supplementation in feed mixture. Significant differences (P <0.05) were found in yolk crude fat content. After phytogenic additive (seeds of Rhus coriaria L.) we found significantly lower crude fat content in all collection, mainly in second eggs collection (628.43 g kg -1 of dry matter in control group vs. 590.37 g kg -1 of dry matter in experimental group). Our results correspond with results published by Arpášová et al. (2010). Authors reported that major effect of a phyto...

In contrast, other authors have reported the beneficial effect of thymol on broiler growth performance (Bassett, 2000;Hertrampf, 2001;Kamel, 2001;Bolukbasi et al, 2006;Cross et al, 2007;Bolukbasi and Erhan, 2007).…”

The effect of the thyme extract and wheat form of the diet on performance, digestive organ weights and serum lipoproteins was studied in 320 male day old (ROSS 308) chicks. From 1 to 42 d of age, 8 diets arranged factorial with 4 thyme extract level (0.0, 0.2, 0.4 and 0.6%) and 2 wheat forms (ground vs whole) was used. Each treatment was replicated 4 times (10 birds per replicate). Thyme extract had no significant effect on body weight gain, feed intake and feed conversion ratio irrespective of wheat form used over whole trial period (1-42 d). From 1 to 21 d of age, broilers fed the whole wheat diet grew faster than the broilers fed ground wheat based diet (609.06 vs 573.34 g). Relative abdominal fat and gizzard weight was significantly higher (P<0.05) in birds fed the whole wheat diets. Two-way interaction between thyme extract and wheat form were observed for total cholesterol, LDL-cholesterol, HDL-cholesterol and very-low-density lipoprotein (VLDL) in the experiment. The results showed that the extract had no effect on performance of broilers irrespective of wheat form used. Relative gizzard weight was higher (P<0.05) in birds fed the whole wheat diets, but an increase in abdominal fat should be taken into account for carcass quality and processing. The predominant effect of thyme extract on lowering lipid levels in broilers fed on wheat based diets was on triglyceride rather than on cholesterol concentrations.
