Numerous studies in animal husbandry are aimed at substantiating the feasibility of using waste from technical industries in animal feeding. Recently, dry post-alcohol bard can be found in compound feed recipes. It is a good source of protein, but its amount in the feed is limited due to the presence of anti-nutrients. Experimental studies of the dynamics of productivity of laying quails for the consumption of complete feed with different proportions of dry post-alcoholic bard were conducted. For this purpose 5 groups of quails of an egg direction of productivity on 30 animals aged 42 days everyone were formed. Quails of the control group consumed complete feed, which did not contain dry post-alcoholic bard. Instead, animals of the 2nd, 3rd, 4th and 5th experimental groups during the main period of the experiment were fed, respectively, 5%, 10, 15 and 20% of dry post-alcoholic bard. The nutritional value of compound feeds of all groups was the same. During 120 days of the main period of the experiment, the most prevalent control animals were quails of the 3rd experimental group, which consumed 10% of dry post-alcoholic bard as part of the feed. Slightly smaller (5.0%) was the predominance of animals of the 2nd experimental group, the content of bards in the diet of which was 5%. The least different from the control indicators were the quails of the 4th experimental group, which only 0.3% outperformed the latter, consuming 15% of dry bard in the compound feed. The share of dry post-alcoholic bard 20% in the complete feed of quails of the 5th experimental group had a negative effect on their productivity, as the gross collection of eggs in this group was less than the control by 1.6%. In addition to differences in the number of collected eggs, the results of the experiment showed a statistically significant difference in the weight of laid eggs between animals of the control and experimental groups. During the main period of the experiment on the average weight of eggs the most control was dominated by birds of the 3rd experimental group - by 1.1%. Slightly smaller (0.7%) was the predominance of animals of the 2nd experimental group. Quails of the 4th experimental group were little different from the control in terms of egg weight - only 0.4% outweighed it. The birds of the 5th experimental group also slightly differed from the control in terms of egg weight - only 0.2% inferior to it. Thus, the inclusion of 5–10% of dry post-alcoholic bard in the feed has a positive effect on the productivity of quails. Key words: dry post-alcoholic bard, eggs, quails, laying, egg weight, compound feed, feeding.

Изучение влияния пробиотического препарата ЭМ-курунга на приросты, анализы крови и помёта птиц проведено на примере цыплят техасских белых перепелов. В качестве объекта исследований использовались цыплята перепелов, начиная с суточного возраста. Средняя масса цыплят на начало эксперимента составила 9,2±0,12 г. Цыплят забивали в возрасте 90 суток. Установлено, что введение в рацион цыплят пробиотического препарата ЭМ-курунга в количестве 0,2 мл на 1 кг живого веса увеличивает сохранность молодняка на 14,8% и приросты птенцов – на 10%. Сравнительный анализ биохимических данных опытной и контрольной групп птицы показал, что введение в рацион опытной группы пробиотика практически не повлияло на белковый обмен. Общий белок у опытной птицы был недостоверно меньше, по сравнению с контролем, на 1,25%, та же картина наблюдалась по уровню альбуминов – меньше на 1,9%, глобулинов – на 1%. Сравнительный анализ показателя кислотности кала птиц опытной и контрольной групп показал достоверное различие. Так, у контрольной группы рН кала имел среднее значение 6,5, у перепелов опытной группы – 7,5. Таким образом, у опытной птицы, в сравнении с контрольной, активная кислотность кишечного содержимого достоверно сдвинулась в слабощелочную сторону, что свидетельствует о благоприятном воздействии пробиотика на микрофлору желудочно-кишечного тракта перепелов, снижая уровень патогенной микрофлоры, активно развивающейся в кислой среде. The study of the effect of the probiotic preparation EM-Kurunga on gains, blood tests and poultry litter was carried out using the example of White Texas quail chickens. Quail chickens starting at daily age were used as the subject of research. The average weight of chickens at the beginning of the experiment was 9.2±0.12 g. Chickens were slaughtered at the age of 90 days. It was established that the introduction of the probiotic preparation EM-Kurunga into the diet of chickens in the amount of 0.2 ml per 1 kg of live weight increases the safety of young animals by 14.8% and the gains of poults – by 10%. A comparative analysis of the biochemical data of the experimental and control groups of poultry showed that the introduction of the probiotic into the diet of the experimental group had practically no effect on protein metabolism. The total protein in the experimental poultry was insignificantly less than in the control by 1.25%, the same pattern was observed in the level of albumin – less by 1.9%, globulins – by 1%. Comparative analysis of the acidity index of poultry feces from the experimental and control groups showed a significant difference. So, in the control group the pH of feces had an average value of 6.5, in the quails of the experimental group – 7.5. Thus, in the experimental poultry in comparison with the control one the active acidity of the intestinal contents significantly shifted to the slightly alkaline side, which indicates a favorable effect of the probiotic on the microbiota of the quail gastrointestinal tract, reducing the level of pathogenic microflora actively developing in an acidic condition.

Effect Of Feeding

The results of the effect of feeding the chelated form of Zinc on the safety, productivity and slaughter parameters of broiler chickens are presented. The aim of this study was to determine the safety, productivity and slaughter parameters of broilers on the background of feeding chelated form of Zinc. Materials and methods. Experimental studies were conducted during 2020 on broiler chickens cross Cobb-500 in the vivarium of the Veterinary Faculty of Sumy National Agrarian University (Ukraine), divided into two groups on the principle of analogues (control and experimental) of 50 broilers each. The source of zinc for chickens in the control group was their sulfates. Chelated forms of Zinc were used for broiler chickens of the experimental group. All groups of broiler chickens were administered the compound with compound feed in a dose that corresponded to the daily requirement of the bird in this trace element. The duration of the experiment is 42 days. The growth and development of broilers were evaluated on the basis of determining the relevant zootechnical indicators. Live weight of birds was determined by individual weighing on scales of the VNC type with an accuracy of ±1 g at the age of 7, 14, 21, 28, 35 and 42 days. Both scientific and economic experiments also determined the preservation of livestock - daily by the number of culled and dead birds. Feed consumption was recorded daily, for each week of cultivation and for the entire period of the experiment. At the end of the experiment, the cost of feed per 1 kg of live gained weight was calculated. Results. According to the results of the conducted researches, it was established that feeding of the chelated form of Zinc probably increased both the average daily gain and the total live weight of broiler chickens at different age periods of rearing. The live weight of chickens at the beginning of the experiment was almost the same, but at 7 days of age it tended to increase in chickens of the experimental group, although a significant difference between groups in this indicator was not found. It was found that the weight of uneviscerated, semi-eviscerated and eviscerated chicken in poultry of the experimental group was greater than similar indicators in the young animals of the control group by 9.3, 9.2, and 9.8 %, and this difference was significant (p<0.01). The yield of semi-eviscerated carcasses was higher in ones of the experimental group (84.19 %), and the difference was significant (p<0.05). Conclusions. It was found that the live weight of chickens of the experimental group (consumption of feed with a chelated form of Zinc) prevailed at 7 days of age by 1.1 g; on the 14th day – on 22.1 g (p<0.01); at 21 days – 35.4 g (p<0.01); at 28 days – 94.5 g (p<0.05); at 35 days – 133.6 g (p<0.01); at 42 days – at 218.9 g (p<0.05). Preservation of young animals in the experimental group, which used chelated compounds of Zinc, was higher and amounted to 96 %, compared with the control – 92 %. By age, feed costs per unit weight gain were lower in the experiment, respectively: 0.05; 0.08; 0.12; 0.06; 0.07 and 0.05 kg, compared to the control group. Growing broiler chickens on compound feed with a chelated form of Zinc by 9.8 % (p<0.01) increases the weight of the eviscerated carcass.

A 12-week study was conducted at the Teaching and Research Farm of the Obafemi Awolowo University, Ile-Ife to evaluate the effect of dietary inclusion of LAYPLUS® (LP) on fertility and egg parameters of female Japanese quails, Coturnix coturnix japonica. Two hundred and ten birds of average weight of 167.75±3.94g were used for this study, and they were allocated randomly into seven treatment groups and replicated thrice. Group 1 served as control without inclusion of LAYPLUS®, while groups 2, 3, 4 and 5 had 250 mg/kg, 500 mg/kg, 750mg/kg and 1000mg/kg inclusion of LP and group 6 had 240mg/kg of vitamin E, respectively, and group 7 clomiphene citrate. Eggs were collected daily and egg production was calculated on a bird-day basis. The data obtained were analyzed using one-way ANOVA. There was significant increase (p<0.05) in the egg production parameters namely egg weight, egg laid per hen and percentage laying rate of LP500mg/kg compared with other groups. The highest percentage egg production was by the LP500mg/kg at 57% while the lowest was by the LP250mg/kg at 41%. There was no significant difference in the egg weight and Haugh unit among the supplemented birds and the control group. There was significant difference among the treatments in the percentage hatchability of the eggs with LP500mg/kg eggs recording the highest value of 95.68%. It can be concluded from this experiment that supplementation of the feed with LP at 500mg/kg had beneficial effect on quail production through improved effect on egg production and hatchability.

The positive effect that innovative techniques have has been a broad debate in recent years especially in the matter of teaching reading comprehension. Semantic map is one of the latest techniques used to develop reading comprehension. The current study attempts to provide a more detailed investigation regarding the effects of using semantic map on students' reading comprehension achievement. To investigate the objective of this paper, a null hypothesis is used claiming that there is no statistically significant difference between the mean scores of the experimental group, which is used semantic map technique in teaching reading comprehension and those of the control group which is taught by traditional techniques. A sample of 60 students has been chosen randomly to be divided into equal groups. After 10 weeks of experiment, a posttest is applied for both groups. Then the T-test is used to collect and analyze the data. The findings from this investigation proved that there is a statistically significant difference between the mean scores of the experimental group and those of the control group in the reading comprehension achievement posttest for the benefit of the experimental group.

Abstract. In the domestic fur farming there is an urgent need to introduce an alternative type of feeding for young minks. The purpose of the work is to study possible of feeding commercial young minks with complete feed, consisting of animal and plant components. Methods. In a scientific and economic experiment on young sapphire minks intended for slaughter, 2 groups were formed according to the principle of analogues, 32 heads each (16 males and 16 females): I – control, II – experimental. The animals of the control group received from 2015 August 5 to September 15 a typical general economic ration in the form of a wet mash, an experimental one – a loose, complete feed (made according to a recipe developed by us, taking into account the current norms), mixed with water in a ratio of 1:2. All experimental studies were carried out using classical zootechnical, pathomorphological, histological, veterinary-sanitary and statistical methods. Results and scope. The dynamics of the live weight of the experimental minks showed that by the beginning of the main period, the males and females of the experimental group lagged behind the control animals, after switching to the main diet for slaughter, the males lag remained and the females caught up with the control animals. But the control and experimental animals did not differ in the length of the carcass. The safety of the livestock was higher in the experimental group: males – 100 %, females – 93.75 %; in control – 93.75 % and 87.5 %, respectively. According to the main productive indicator – the quality test – the skins of the control and experimental animals did not have significant differences. Thus, the development of an alternative type of feeding is quite possible, but it requires improvement in the direction of increasing the coefficient of digestibility of nutrients and adaptation of males to an uncharacteristic type of feeding. Scientific novelty. The prospects and the need to introduce an alternative type of feeding the commercial young stock of minks with full-feed compound feeds into the domestic fur farming are outlined.

Playing in general has a positive effect on child development; yet with the advancement of technology, the way children play has changed, and the effects of their play have changed as well. Some studies have shown an overall negative effect of electronic games, while others have reported the opposite. This study aims to investigate the effects of tablet-based electronic games on the child’s self-concept. Twenty-six children between the ages of 4 and 6 years from low-income backgrounds participated. They were divided into two groups; in the experimental group, children were given a tablet device with 10 educational electronic games on it, and the mothers were instructed to let them play the games for less than three hours a day in a normal home situation. The control group was not given any electronic devices. A pre- and post-pictorial measure of self-concept was used. The overall results showed no gains in self-concept for the experimental group and no differences between the groups, except in the domain of curiosity, where the control group children experienced a pre- to post-test increase.

The main aim of the study was to assess the effect of a diet supplemented with L-carnitine on egg weight and laying rate in hens of pheasant (<I>Phasianus colchicus</I>). The experiment lasted 14 weeks and was performed with 210 experimental and 210 control laying hens. The birds were kept in cages; one cock and seven hens per cage. Both control and experimental hens were administered the complete feed mixture, with the only difference that the feed mixture administered to experimental hens was supplemented with L-carnitine at a level of 0.01%. During the experimental period, eggs were collected and weight of individual eggs was determined. Control and experimental groups provided 8 039 and 8 499 eggs, respectively. The results showed that L-carnitine increased egg weight (<I>P</I> < 0.01) and laying rate. The effect of L-carnitine on egg weight and laying rate manifested itself until weeks 11 and 13, respectively. The average weight of eggs laid during the experimental period was (mean ± SD) 32.22 ± 3.03 g in the control group and 32.51 ± 2.83 g in the experimental group, with the overall laying rate being 44.29% in the control group and 47.30% in the experimental group.
