Pre-natal (PN) and post-hatch (PH) assessments were carried out on two broiler chicken strains to examine possible origin of strain differences and response to heat stress. One hundred and forty fertile eggs incubated for 18 days as PN and 192 day-old broiler chicks as PH; were evenly divided between two strains (Arbor Acres [AA] and Marshal [MS]). For the PN assessment (day 18, 19 and 21 of incubation), embryos were dissected and organs weighed. Liver glycogen and moisture content of the carcass and residual yolk sac were also determined. Post hatch, average body weight (ABW), average daily feed intake (ADFI) and feed conversion ratio (FCR) were measured under high natural ambient temperatures. At d 18 of incubation, proportional breast weight and yolk moisture was higher in AA than MS (P < 0.05), with the same trend observed at d 21 for yolk weight (%). Breast, gizzard, heart and liver weights were observed to increase linearly, in proportion to weight of embryo (P <0.001), between d 18 and 21 on incubation, while the inverse was observed for yolk weight (%). Post-hatch, ADFI and FCR at the end of the starter phase were lower in MS compared with AA (P < 0.05). However, at the end of the finisher phase, only ADFI was significantly influenced by strain of broiler (AA < MS; P < 0.05). Serum electrolytes and carcass characteristics did not differ between strains (P > 0.05). Phenotype differences in were manifested prior to hatch, with Marshall exhibiting advantage to Arbor Acres under high ambient temperatures.

The research was aimed to determine the volume and time of giving the natural antibiotic which are optimal for the value of Index Performance (IP) of broiler chickens. The first treatment variable was: giving natural antibiotics with a dose for partition 1 0.05mL / 40 mL water / chicken / day, partition 2 0.1mL / 40 mL water / chicken / day, partition 3 0.15mL / 40 mL water / chicken / day, partition 4 (synthetic antibiotics as a comparison) and carried out for 35 days in a fixed time of 24 hours. Optimal results with the best Index Performance (IP) obtained from the first variable followed by the second treatment variable, the time of giving natural antibiotics for partition 1 given once a day, partition 2 every two days, and partition 3 three days with a constant giving dose  0.15 mL / 40 mL water / chicken / day for 35 days. The parameters observed were: (1) average body weight, (2) weight gain, (3) feed consumption, (4) feed conversion, and (5) number of live chickens. From these data the IP of broiler chickens was calculated and from the two variables obtained the optimal dose and time of giving natural antibiotics. Based on research results from the product, the best of giving natural antibiotic volume is 0.15 mL / chicken or equal to 4.2 mL / 28 chickens which it is able to increase the value of broiler chicken IP until harvest time. From the optimal results obtained in the trial volume variation of giving natural antibiotic, the experiment can be continued with the aim of determining the optimal time of giving herbal antibiotics namely the best results are obtained once a day for 28 chickens because it shows that the giving natural antibiotic is able to increase the IP value of broiler chickens until harvest.

The article presents the results of studying the impact of the spore-forming probiotic “Olin” and the prebiotic “Eсofiltrum” on the meat quality of broiler chicken carcasses of the Ross-308 cross. In the course of the research, it has been found that the inclusion of these preparations in the broiler diet has a positive effect on the studied indicators: the pre-slaughter weight increased by 4.3-5.7%, the weight of the gutted carcass by 4.6-6.2%, the muscle weight 4.8-6.5%, the weight of the loin muscles by 5.7-8.2%. The ratio of edible parts to inedible parts is 4.14 in the third experimental group, 4.08-in the second, and 4.04-in the control. Based on the results of the anatomical cutting of broiler carcasses and according to the fatness indicators the poultry carcasses of the third and second experimental groups, 87.5% and 87.2%, respectively, belong to the first grade, and the yield of the first grade carcasses is 86.2% in the control group. Meat products obtained from both the control poultry and the poultry of both experimental groups has no off-aroma odor and taste, the meat is juicy, tender and aromatic. The products obtained from broiler chickens, whose ration includes the probiotic “Olin” and the prebiotic “Ecofiltrum”, do not have any deviations from the established standards and norms. During the research, it has been found that the use of the studied drugs has a positive effect on the meat quality of poultry carcasses. However, broiler chickens receiving the probiotic “Olin” has more pronounced meat qualities.

Vegetable feed additive “Biostrong 510” based on essential oils and plant substances contains active substances exclusively of vegetable origin, which have a more intense eff ect on the animal’s body. The mechanism of action is based on the synergism of several plant substances containing active substances that, when combined, aff ect a certain category of animals. The additive contains essential oils, herbal plants, and seasonings such as anise oil, thyme oil, gentian powder, chili paprika powder, and quillaya extract. The purpose of the research was to determine the feasibility and eff ectiveness of fortifi cation of compound feed with the vegetable feed additive based on essential oils and vegetable substances to increase meat productivity and meat quality. In order to study the eff ectiveness of feeding vegetable feed additive in compound feed for broiler chickens under the conditions of LLC “Akashevskaya poultry Farm” in the Republic of Mari El, a scientifi c and economic experiment has been carried out. Experiments have been performed on broiler chickens of the cross Cobb-500 from the daily to 40-day age of the birds. The eff ect of the vegetable feed additive “Biostrong 510” based on essential oils and vegetable substances on meat productivity and nutritional value of broiler chicken meat has been studied in the paper. The level of feeding and the quality of the feed consumed by poultry has a big infl uence on meat productivity. The use of our selected vegetable feed additive based on essential oils and vegetable substances increase the slaughter weight by 9,0–13,7 %, the slaughter yield by 2–5 %, the amount of muscle tissue and meat qualities of carcasses. The best results have been obtained by including the vegetable feed additive based on essential oils and plant substances in the amount of 0,015 % of the dry substance of the feed.

The bread-making quality of forty commercial winter wheat samples, grown in the western region of the CzechRepublic, and their flours (white flours with ash content of about 0.5%) prepared in a commercial mill was studied. Standard analytical methods (ash and protein content, wet gluten), amylolytic activity measurement (falling number), rheological investigation (alveograph, gluten index), sedimentation test and laboratory baking test were used for characterization of wheats and flours. In addition NIR method was used to calculate ash, wet gluten, sedimentation value and protein content. Statistically significant correlations were found practically between all tested quality parameters of wheat and corresponding flour samples. However, the strongest correlation (r = 0.69&ndash;0.70) significant at 0.01 level exists between specific bread volume and protein and wet gluten content, determined both by standard or by NIR methods.&nbsp;

Pituitary Homogenate

The results of reproduction were tested in females of the African catfish (Clarias gariepinus Burchell 1822) after stimulation of ovulation with carp pituitary (4 mg/kg body weight) or with Lecirelin (15 &mu;g/kg) and metoclopramide (10 mg/kg). After administering the synthetic substance eggs were obtained from all females while in the group treated with pituitary homogenate 7 out of 8 hypophysed females spawned. The applied spawning agent did not significantly influence the weight of eggs expressed in grams, but in the case of females treated with carp pituitary homogenate a significantly higher weight of eggs expressed as the percentage of body weight of fish was recorded. The applied stimulators of ovulation did not affect any trait reflecting the quality of eggs. Females used as an experimental material belonged to two categories in respect of body weight: lighter females with average body weight of 2.63 &plusmn; 0.36 kg and heavier females with average body weight of 3.91 &plusmn; 0.48 kg. It was proved that the weight of eggs expressed either in grams or as a percentage of a female&rsquo;s weight was significantly related to the body weight of a female (P &le; 0.01 and P &le; 0.05, respectively), as well as the percentage of fertilised eggs and the percentage of living embryos after 28 hours of incubation (P &le; 0.05 and P &le; 0.05, respectively). The interaction between the stimulator of ovulation and the female body weight was significant only for traits reflecting the weight of obtained eggs (P &le; 0.05 and P &le; 0.01). &nbsp;
