Day-old male 240 chicks of a Ross 308 strain were used to test the effects of an commercial organic acid (OA), Biotronic SE Forte, on broiler performance and gut histomorphology. OA preparation was supplemented at 3 g/kg level into starter and finisher broiler diets of standard (NRC, 1994) or lower (approximately 10%) nutrient density (ND). Thus, the experiment was set up according to 2x2 factorial design with 6 reps of 10 birds allocated in each. BWG and FCR of broiler chicks both at 21 and 35 d experimental periods were significantly (P<0.001) improved by OA supplementation regardless of the diets ND. OA supplementation increased BWG by approximately 20% in 21 and 12% in 35 d experimental periods. FCR value dropped from 1.276 to 1.105 and from 1.263 to 1.129 in the two group fed with standart or

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

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

Three dietary combinations of probiotics and phytogenics administered sequentially or continuously were assessed for their effects on broiler performance, nutrient digestibility, caecal microbiota composition, volatile fatty acid (VFA) pattern and plasma total antioxidant capacity (TAC). One-day-old Cobb male broilers (n = 525) were allocated to five experimental treatments for 42 days. Each treatment had three replicates of 35 broilers each. Depending on the time-frame of sequential or continuous addition in the basal diet (BD) of the probiotics (108 CFU/kg BD) and phytogenics (125 mg/kg BD), experimental treatments were: control (no additions, Days 1–42); PE1, probiotic Days 1–14 and phytogenic Days 15–42; PE2, probiotic Days 1–28 and phytogenic Days 29–42; PE3,

The aim of the research is to investigate the influence of phytogenic preparation „Biomin P.E.P – 1000“, which is of a natural origin, on the processes of albumen metabolism in the organism of broiler chickens. Biomin P.E.P – 1000 positively stimulates the activity of the alimentary tract of broiler chickens as well as a composition of intestine micro flora, consequently that conditions better digestion of nutrient substances. 3 groups of broiler chickens were researched. The chickens of the first group were fed with the feed mixture, containing a feeding antibiotic Flavomicin-80, in the feed of the second group of chickens a feeding antibiotic Flavomicin – 80 was replaced by a dry phytogenic preparation „Biomin P.E.P–1000“, and in the drinking water of the chickens of the third group a liquid phytogenic preparation,

The effects of dietary supplementation with two phytogenic feed additives (PFA) on performance parameters were investigated using 1200 mixed sex broilers fed standard diets or diets with reduced energy and amino acid concentrations. Birds were assigned to 6 treatments with 5 replications each and either fed a standard basal diet or a re-formulated basal diet with 1.5% reduced energy and amino acid concentrations. Treatments were: (1) Standard diet; (2) as 1 + PFA-1; (3) as 1 + PFA-2; (4) Re-formulated diet; (5) as 4 + PFA-1; (6) as 4 + PFA-2. PFA-1 was a blend of essential oils from oregano, anise and citrus adsorbed to an organic carrier (dosage: 0.125 g/kg) and PFA-2 was blend of essential oils from oregano, thyme, anise and citrus, encapsulated in a carbohydrate matrix (dosage: 0.1 g/kg).
