The work analyses the influence of citrate nanomolibden (CNM) and food additive (FA) «Probics» which is had on the slaughter indicators of broiler–chickens (pre–slaughtered mass, mass of non–cleaned carcass, mass of half–cleaned carcass, mass of cleaned carcass, mass of slaughtered carcass, mass of internals, and mass of internals in comparison with slaughtered outcome). The author determines that the broiler–chickens’ mass of the tested groups before being slaughtered as well as the mass of non–cleaned, half–cleaned and cleaned carcasses is definitely more than the same indicators of the controlled groups. Broiler–chickens’ slaughtered outcome has the biggest quantity in the tested groups in comparison with the controlled ones because the ration of the tested groups has been enriched by citrate of nanomolibden (CNM). For certain, the same indicator of broiler–chickens of the tested group, the ration of which has been enriched by food additive (FA) «Probics», does not differ from the controlled group but it is a little bit higher. Thus, the work highlights that the use of CNM in concentration 0.24 mg/dm³ has a positive influence on the indicators of slaughtered broiler–chickens in comparison with the controlled group as well as with the broiler–chickens’ group the ration of which has included FA «Probics». Having the aim to distinguish the functional load which is had on the viscera of the used nutraceuticals it has been set out that the mass ratio of edible organs such as liver, heart, muscular part of a stomach of broiler–chickens of the tested and controlled groups of pre–slaughtered outcome. The work proves that the mass of broiler–chickens’ viscera of the tested group such as liver, heart, muscular part of a stomach is relatively bigger in comparison to the control but their ratio to the slaughtered outcome has an opposite appropriateness.

Lipid Status

The aim of this study was to investigate the effect of dietary garlic powder addition on productive performance and blood lipid status of broiler chicken. At the beginning of experiment, three treatments of 150 one day old broiler chickens of hybrid line Hubbard per treatment, on a total of 450 chickens were formed. Every treatment was divided in four groups which represents four replicates of the experiment. Control treatment (T1) was fed with mixtures without addition of garlic powder, while experimental treatments were fed with addition of 0.5% (T2) and 1.0% (T3) of dietary garlic powder, respectively. Experiment lasted 42 days. After the completion of experimental period the highest achieved body weight of chicken was at treatment T2 (2371.1g) which was followed by treatment T3 (2336.1 g) with statistically significant differences (p<0.05) compared to control treatment. For the entire experimental period, feed conversion ratio was lowest in treatment T2 (1.8 kg/kg) and the highest in control treatment T1 (2.1 kg/kg), without statistically significant (p>0.05) differences. Addition of garlic powder led to a statistically significant (p<0.05) increase in values of EBI in compare to a control treatment T1. The highest mortality rate (5.1 %) and the lowest EBI (220.4 %) were recorded in control treatment. Addition of garlic powder in the amount of 1.0% (T3) significantly (p<0.05) decreased LDL concentrations in blood serum. The lowest concentration of total cholesterol was recorded at treatment T2 (p<0.05). The highest concentration of HDL (44.8 and 39.6 mg/dl) was recorded in treatments T3 and T2. It could be concluded that the addition of garlic has positive influence on chicken production and blood lipid status, but the further investigation of their mode of action is still necessary.

Label Statement

Antimicrobials premixes are the presentation of choice to administer drugs simultaneously to groups of animals in intensive husbandry systems that require treatment for pathologies of bacterial origin. Among the premixes available for use in poultry, florfenicol and oxytetracycline are commonly administered via food or water. However, their actual concentration in premixes must meet on-label statements to ensure plasma concentrations reach effective therapeutic levels. Hence, this work was designed for the purpose of verifying whether the concentration of antimicrobial present in five premixes matched their on-label statement. Three oxytetracycline premixes, and two of florfenicol, were analysed using a Xevo TQ-S micro UPLC-MS/MS, and an ABSciex API4000 HPLC-MS/MS, respectively. Analytical methodologies were implemented and validated, showing an R2 ≥ 0.99 for the calibration curves. Oxytetracycline was detected in these premixes at concentrations exceeding on-label statements by 13.28%, 21.54%, and 29.68%, whereas florfenicol concentrations detected in premixes were 13.06% and 14.75% lower than expected. Consequently, this work shows that the concentration of active ingredients that are present in commercial formulations effectively differ from those stated on premix labels, and it also highlights how unpredictable their range of variability might be. This must be addressed through solid and updated laws that guarantee an effective pharmaceutical product.

The cultivation of Chironomus larva under artificial conditions needs necessary conditions in the vivarium to provide the biological characteristics of its reproduction, growth and development. Chironomus larva is biologically valuable feed and source of protein for many young species of fish. Being the natural feed it is of great demand now days. The article presents the research results connected with the optimal water mass ratio and the nutrient medium for Chironomus larva. It has been prouved that the auxiliary agents have positive influence on Chironomus mosquitoes egg laying. The study has been conducted in the vivarium of Bila Tserkva NAU Research Institute of Food and Animal Products Processing Technologies. The observation methods and statistical techniques have been used to establish the optimal technological parameters. It has been scoped that Chironomus larva survives better in the nutrient medium, where the water mass ratio of silt is 1:5 and 1:6. There is a bigger amount of larva survival in these examples (in 5.6% times) in comparison with the control group (the ratio of water to silt is 1:2). There is the biggest amount of Chironomus larva deathratein the medium with the water mass ratio of silt 1:1. The use of auxiliary agents in the nutrient medium has a positive effect on Chironomus egg laying. After washing the nutrient medium, it was found that the optimal amount of auxiliary agents was 40 items bigger (20 floating and 20 immersed in sludge), but their use allows to increase the number of eggs laid in 1.2 times. Key words: silt, cultivation biotechnology, Chironomus, larvae, auxiliary agents, water to silt ratio, the survival of Chironomus larvae, water.

The Moment

At the moment, an important issue for medicine and veterinary sciences is the lack of iodine and selenium in human and animal bodies. The problem of I, Se, and S deficiency in livestock has not been solved yet, which motivates the development of new effective compounds of these elements. Particularly noteworthy are the citrates of minor nutrient elements included in mineral premixes and feed additives used to balance mineral nutrition in the diets of animals and poultry. The purpose of this paper is to study the efficacy of different doses of I, Se, S citrate on the intensity of metabolic processes in the body of chicken broilers before and after the intragastric introduction of E. coli. It was found that watering of chicken broilers with I, Se, S citrate has antibacterial action. As a result of the conducted studies, it was revealed that the applied doses of I, Se, S caused both prophylactic (E2) and therapeutic (E4) effect on the development of colibacillosis in broiler chickens. This effect is more pronounced with higher doses of Iodine (20 μg/dm3) in I, Se, S citrate for therapeutic purposes, which contributed to the 100% preservation of the chicken population. High metabolic activity of low doses of I, Se, S citrate with a content of 2.5 μg I dm3 was noted. It provided the highest weight gain of chickens and reaching 780 g on the 35th day of growing, or 121.5% versus control and 788.4 g (119.9% versus control) on 42nd day of growing in the vivarium. The obtained data indicate a positive influence of watering I, Se, S citrate with a content of 20 μg I/dm3, which was characterised by 100% preservation of chickens throughout the growing period

The aim of this study was to evaluate the effect of simvastatin (SIM) and L-carnitine (LC) additives and their interactions, on productive performance and carcass quality of broilers. For this purpose, a feeding trial was conducted, under 3×3 factorial design, using SIM at 0, 1 or 2 g/kg level and LC at 0, 150 or 300 mg/kg level in a basal-diet and originating a total of nine treatments: T1 (control-diet, 0/0), T2 (0/150), T3 (0/300), T4 (1/0), T5(1/150), T6 (1/300), T7 (2/0), T8 (2/150), and T9 (2/300). Feed intake was higher in T2 (4716 g), T7 (4722 g) and T9 (4698 g) than in T1 (4545 g; P<0.05) considering the last growing phase (35-42 days) or whole 42-day production cycle. An improvement of feed efficiency was also observed in T8 (1.64) and T9 (1.67) when compared to T1 (1.77; P<0.05), and these were mainly due to SIM × LC interactions (P<0.05). The LC influenced positively (P<0.05) the weight of eviscerated carcass, breast, drumsticks and abdominal fat, as well as plasma triglycerides level. This findings suggests that the combination of SIM and LC additives have a positive influence on growth performance and carcass traits of broiler chickens.

The objective of this study was to evaluate the performance of broiler chickens in different lighting programs. Broiler chickens were fed on feeders of different colours at different breeding phases. In total, 240 Cobb500™ chicks mixed at 1 d of age were used. They were distributed in a completely randomized design. The treatments followed a 2 × 4 factorial design: two lighting programs (continuous and intermittent), and four colours of feeders (white, green, blue, and red). The birds were evaluated for weekly productive performance and the data were submitted to analysis of variance and later Tukey’s test for comparison of means. In the periods 1–7, 1–21, and 1–42 d of age, lighting programs and feeder colours affected weight gain, feed intake, and feed conversion. Intermittent red feeders influenced positively the performance of birds. It is possible to replace conventional lighting programs for intermittent lighting programs. Red feeders exert a positive influence on the performance of broiler chickens.

Mutual Correlation

The use of betaine can influence the resistance, production performance and quality of broiler carcass, and potentially it can reduce the need for choline and methionine in food due to the mutual correlation of these three substances in the organism. Objective of the paper was to investigate the effect of full substitution of added DL-methionine with betaine in diets for broilers on production and slaughter parameters in conditions of optimal amount of choline in the feed. Study was carried out on 1725 one day old broiler chickens of Cobb 500 hybrid divided into 3 groups: Control group (C) fed complete forage mixtures with usual addition of DL methionine and two trial groups where methionine was substituted by 1g (B1group), and by 2g of betaine per kilogram of mixture (B2 group). Research results indicate that the full substitution of supplemented methionine with betaine in feed can have positive and negative impact in broiler fattening. Negative effects on final body mass, gain and feed conversion were determined in broilers fed mixtures where 1g of synthetic methionine was replaced with 1g of betaine preparation, and at the same time positive influence on mortality was observed, especially in broilers fed diets containing 2g of betaine. Production index showed no significant differences between trial groups, as well as studied broiler carcass quality parameters.
