“…The beneficial influence of the herbal mixture on poultry growth and the better feed conversion ration could be also explained with the antioxidant activity of carvacrol, thymol, cineol and pinene -components of thyme, oregano and rosemary (Faleiro et al, 2005;Hazzit et al, 2006).…”

The experiment was carried out with dual-purpose fowls developed for rural backyard farming -indigenous Katunitsa chicken (line "AN"), in a free range management system from hatching to 52 weeks of age. The purpose of the investigation was to establish the influence of a blend of herbs as a dietary supplement on some serum biochemical parameters (alanine aminotransferase, aspartate aminotransferase, total cholesterol, gamma-glutamyl transferase, triglycerides and creatinine), growth performance, egg production, egg fatty acid composition, and health status. The composition of this blend of herbs included: 0.05% garlic powder (Allium sativum), 0.3% cinnamon powder (Cinnamomum verum) and 0.03% of each of the following dried herbs: yarrow (Achillea millefolium), rosemary (Rosmarinus officinalis), thyme (Thymus serpyllum), basil (Ocimum basilicum) and oregano (Origanum vulgare). The birds were divided into two groups -control (n=60) without supplemental mixture to the diet and experimental (n=700) with supplemental mixture to the diet from the first day of age to the end of the experiment. The results showed that the herbal mixture supplement decreased significantly the blood serum cholesterol and triglyceride levels -at 7 (P<0.001) and at 52 weeks (P<0.05) of age. The content of phospholipids, triglycerides and linoleic acid in the egg yolk was higher in the experimental group compared to the control group (Р<0.05). There was no significant difference in the egg yolk cholesterol levels between both groups (P>0.05). Over the entire investigation period the chickens from the experimental group had a better feed conversion ratio (with 3.37%) and a higher egg laying capacity (with 1.79%). At the end of experiment (52 weeks of age), hens from the control group exhibited generalised fatty degeneration of liver parenchyma, while these in experimental group, the major part of hepatocytes had no fat droplets in their cytoplasm. The death rate from 0 to 7, from 8 to 21 and from 22 to 52 weeks of age was 18.33%, 0% and 8.57% in the control group and 1.00%, 0.26% and 2.62% in the experimental group, respectively. Therefore in conclusion, it can be affirmed that the use of this blend of herbs had a beneficial effect in the treated fowls and improved their egg productivity, vitality and health condition.Keywords: blood biochemical parameters, chickens, dried herbs, egg production, garlic, growth performance, mortality РезюмеПроучването е проведено с кокошки от общоползувателно направление, предназначени за свободно отглеждане във фамилни ферми -Катунска кокошка, (линия "AN") от излюпване на пилетата до 52-седмична възраст.

“…The essential oil derived from thyme and oregano (carvacrol and thymol) is known to possess in vitro antimicrobial, antifungal and antioxidant activities (Faleiro et al, 2005;Hazzit et al, 2006). Recent studies on experimental animals have revealed that some ingredients of popular herbs and spice plants, e.g., capsaicin or curcumin, can also stimulate digestive enzymes, bile fl ow and enhance bile acid secretion (Platel and Srinivasan, 2001).…”

A study on male turkeys was conducted to evaluate the physiological and growth effects of organic acids, organic acids with essential oils or herbal extract added to diets. The control diet (C) contained premix without any feed additives. Three experimental diets were fed from 1 to 140 days of age: diet A with a blend of organic acids (formic acid and propionic acid) in the amount of 5.0 g/kg of feed, diet AO with a blend of organic acids (citric, fumaric, orthophosphoric and malic acid) and with a mixture of essential oils (from citrus fruits, cinnamon, oregano and thyme) in the amount of 0.5 to 1.0 g/kg of feed, diet HE with preparation composed of oregano essential oil, spice extracts of turmeric and capsicum in the amount 0.3 g/kg of feed. Gastrointestinal tract development and metabolism (after 56 days of feeding) as well as growth performance and carcass characteristics (after 140 days of the experiment) were evaluated. Dietary supplementation with A, AO or HE signifi cantly decreased the pH of the crop contents, but had no effect on the pH of the caecal digesta. Dietary supplementation with A or HE increased the activity of α-glucosidase in the ileal digesta. The tested supplements had no infl uence on SCFA production in the caeca. All supplements increased the body weights of turkeys, but the differences were signifi cant (P≤0.01) only at the age of 84 days. The fi nal body weight (at 140 days of age) of turkeys fed diets with the tested supplements were higher by 3.3-3.9%, and feed conversion ratio decreased by 2.4-5.3% (statistically non-signifi cantly) in these treatments, compared to the control. Generally, carcass traits were not infl uenced by the above feed supplements.
