This study investigated the effect of dietary supplementation with the fermacto prebiotic and Biotronic S.E (an acidifier) on the growth performance, carcass characteristics and serum biochemical parameters of broiler chickens. 240 day old Ross 308 broilers were equally distributed into 24 floor pens and reared for 42 days. A basal diet was formulated according to the recommendations of NRC for starter (1 to 21 days) and grower (22 to 42 days) periods and considered as control diet. Four tested diets were formulated as listed control diet (without any additives), fermacto prebiotic, Biotronic S.E (an acidifier) and mixture of fermacto prebiotic plus Biotronic S.E. Six replicate were used for each treatment. The results of this study indicate that addition of fermacto prebiotic and Biotronic S.E increased the final body weight,

The present study aimed to evaluate immunohistochemical changes of mucinand serotonin-releasing cells in the small intestine induced by various dietary supplementations in quails. A total of 300 one day old quails were randomly divided into 5 equal groups according to the 5 weeks long supplementation: whereas birds of the group 1 were fed with basal diet, the others were supplemented with prebiotics/probiotics (1 g/kg food, group 2), with organic acids (4 g/kg food, group 3), with both prebiotics/probiotics and organic acids (same dosages, group 4) or with antibiotic (active form of avilamycin, 10 mg/kg food, group 5). Weight growth and food intake were not modified among groups. Density of goblet cells were markedly increased mainly in ileum in all supplemented groups

The potential of organic acids in feed preservation, protecting feed from microbial and fungal destruction, but also directly in the animal nutrition is already known for decades and was proven in uncounted laboratory and field trials. However, the knowledge of effects from synergistically acting organic acid blends of high biological value together with organic or inorganic physiologically active carriers to the animal is relatively new. A trial with broiler chicken over a period of 35 days was carried out with an organic acid blend on an inorganic carrier (3 kg inclusion rate per ton of feed) against a control without an acidifier. Results proved significantly (p < 0.05) the growth enhancing action of the acidifier. From this results it can be concluded that acidifiers containing well balanced acid combination can increase

جهت بررسی تاثیر سطوح مختلف اسیدهاي آلی (مکمل حاوي اسید پروپیونیک و اسید فرمیک) بر عملکرد جوجه هاي گوشتی، طرح کاملا تصادفی در چهار سطح (صفر، 5/0، 0/1 و 5/1 درصد در جیره) و سه تکرار که جمعا 12 واحد آزمایشی را تشکیل می داد و با د ر نظر گرفتن 16 قطعه در هر واحد آزمایشی، جمعاً بر روي 192 قطعه جوجه گوشتی انجام پذیرفت. تجزیه وتحلیل آماري داده ها با استفاده از بسته نرم افزاري ماستات-سی مقایسه میانگین ها از طریق آزمون دانکن انجام پذیرفت. تفاوت معنی داري د ر دوره هاي مختلف از نظر میزان مصرف خوراك در بین تیمارهاي آزمایشی مشاهده نگردید. اما افزایش وزن بدن در طی دوره آغازین در بین تیمارها تفاوت معنی داري داشت. علیرغم اینکه با افزایش سطح استفاد ه از اسیدهاي آلی در دوره رشد و کل دوره (42- 0 روزگی) افزایش وزن بدن بهبود یافته بود

The aim of the study was to determine the effect of a phytogenic additive on blood serum indicator levels and faecal nutrients digestibility. The experiment was realized in Riding Centre of the Department of Animal Husbandry, Faculty of Agrobiology and Food Resources, Slovak University of Agriculture in Nitra. Total 14 warm blood sport horses (geldings) were used (7 horses in control group, 7 horses in experimental group respectively); Slovak warmblood bred, average body weight 525 ±75 kg and 6.8 ±3 Years. The control group of horses were fed by crimped barley, meadow hay and mineral feed mixture. Feed rations in experimental group were supplemented with a phytogenic additive containing a blend of essential oils from origanum, anise and citrus, as well as a prebiotic rich in fructooligosaccharides.

این مطالعه مزرعه ای به منظور بررسی تاثیر استفاده از یک افزودنی حاوی ترکیبات فایتوژنیک بر عملکرد گاوهای شيری تحت تنش حرارتی انجام شد. دمای منطقه در زمان آزمایش از محدوده تنش حرارتی به طور پیوسته بالاتر بود. 204 راس گاو زایش اول در این مطالعه استفاده گردید که در دو سالن با جایگاه فری استال قرار داشتند. گروه اول (شاهد) جیره کاملا مخلوط (حاوی 64 درصد کنسانتره و 36 درصد علوفه) و گروه دوم علاوه بر جیره کاملا مخلوط روزانه با 15 گرم به ازای هر راس دام از یک افزودنی تجاری (مخلوطی از ترکیبات فایتوژنیک و فروکتوالیگوساکارید) تغذیه شدند. دوره ازمایش 35 روز ادامه یافت بطوریکه در طول این دوره مصرف خوراک، تعداد تنفس، تعداد گاوهای حاضر در سر آخور خوراکدهی دو روز در فواصل یک ساعته و برخی متابولیت های خون اندازه گیری شد. مصرف ماده خشک در گاوهایی که افزودنی دریافت کرده بودند نسبت به گروه شاهد بیشتر و تعداد گاوهای حاضر در سر آخور نیز در برخی ساعات از گروه شاهد بیشتر بود. اما تولید شیر و ترکیبات آن، شمار سلولهای بدنی و اکثر متابولیت های خونی تحت تاثیر قرار نگرفت.

The aim of this study was to determine the effect of a phytogenic additive in sport horses feed rations on faecal macroelements digestibility. The experiment was realized in Riding Centre of the Faculty of Agrobiology and Food Resources, Slovak University of Agriculture in Nitra, using 6 warm blood sport horses (geldings). The control group was fed with crimped barley, meadow hay, feed mixture and mineral premix. The experimental feed rations were supplemented with a phytogenic additive containing a blend of essential oils from origanum, anise and citrus, as well as a prebiotic rich in fructooligosaccharides. Higher digestibility of calcium (Ca) (71.11% vs. 69.09%) and phosphorus (P) (52.74% vs. 47.55%) was determined in horses fed the phytogenic additives (P>0.05).

The effect of phytogenic preparation Biomin P.E.P.-1000 on the growth of chicken broilers was analysed. The active component of Biomin P.E.P.-1000 is a herbal formula consisting of phytobiotics and polyfructosans. All active substances in this preparation are of plant origin, which do not cause antibiotic resistance and do not leave residues in animal products. The investigation was carried out with broilers Cross Hibro-G at 1 - 42 days of age in Poultry Farm “Vilniaus paukštynas” and in the Research Laboratory of Biological Diversity and Technologies, Vilnius Pedagogical University. The experiment was held with three groups of broilers and every group contained 100 chickens. The chickens of the control group received antibiotic Flavomicin-80 in their diet. The chickens of the other two groups

Two separate performance trials were conducted to determine the effects of postpelleting feed or drinking water application of a Lactobacillus-based probiotic, alone or in combination with a phytogenic product, on growth parameters of broilers fed medicated or nonmedicated diets. Trial 1 consisted of 1,000 straight-run broilers that were randomized, placed in floor rearing pens, and fed medicated diets. At the conclusion of the experiment, BW of broilers receiving the probiotic were not different (P > 0.05) when compared with control broilers. In trial 2, stocking densities were increased to simulate local industry rearing practices, resulting in a total placement of 1,880 chicks in the same rearing facility. Broilers in trial 2 were fed nonmedicated diets. Broilers administered the probiotic by

Because of pending and current regulations, the poultry industry is searching for alternatives to growth promoting antibiotics which may include plant-derived supplements which may prevent or lessen the severity of coccidiosis. Therefore, a 2 x 2 experiment (8 pens / treatment, 26 birds / pen) was conducted with 2 doses of a coccidial vaccine (1X or 5X; Paracox® 5 administered at 1 d of age) with or without supplementation (125 g/1000 kg) with a phytogenic feed additive containing essential oils from oregano, anis and citrus peel (Biomin®P.E.P. 125 poultry). Within each pen, 13 birds received the coccidial vaccine while the remainder was naturally infected through recycling of oocytsts in the litter. One of the naturally infected birds/pen was euthanized for histological evaluation of the mid-ileum
