The sensitivity of the organism of broiler chickens artificially infested with a mixture of three types of eimeria to anti-eimeria drugs used in the Belgorod region was determined. For the experiment, synthetic coccidiostatics (decoquinate, maduramycin, nicarbazine, robenidin), ionophore antibiotics (lasalocid, monensin, narazine) and a complex phytobiotic “AdiCox AR” were taken. The smallest loss of live body weight of chickens was observed when feeding them in the diet of lasalocid, then decoquinate. Feeding the specialized feed additive “AdiCox AR” ensured the preservation of gains in live weight of chickens by 19.0% less than the most effective ionophore antibiotic lasalocid in our experiments. Then, in descending order, followed: narazine 10%, monensin 20%, nicarbazine 25%, maduramycin 1%, robenidin 6.6%. In connection with the obtained results, we consider it expedient to use lasalocid 15% at a dose of 500 g / t feed, decoquinate 6% at a dose of 500 g / t feed and AdiCox AR at a dose of 300 g / tons of feed. The use of narazine 10%, monensin 20%, nicarbazine 25%, maduramycin 1% should be carried out under constant monitoring of the sensitivity of the pathogen to the listed drugs. We consider the use of robinidin 6.6% inappropriate.

The aim of the study was to determine the effect of supplementing broiler chickens’ diets with halloysite on daily body weight gain (BWG), feed conversion ratio (FCR), daily water consumption (DWC), and some broiler house hygiene parameters. The trial was conducted on 18,000 broiler chickens divided into two groups throughout the 42-day (D) rearing period. The birds were fed complete diets without (group C) or with halloysite addition (1%, group E) from D8 of rearing. No difference in the mortality rate was observed between groups C and E. Birds from group E had a tendency (0.05 < p < 0.10) towards a higher body weight at D32 and D42, a higher BWG, and a lower FCR compared to group C during the entire rearing period. Average DWC differed only in the finisher period, with a tendency towards lower overall DWC in group E. The concentration of ammonia in the air from D21 to D35 was increased more than 5-fold in group C but only 1.5-fold in group E. In conclusion, the use of halloysite as a feed additive in the diet of broiler chickens resulted in a reduction in feed consumption per unit of BWG and higher utilisation of crude protein, which led to improved environmental conditions.

The present study was conducted to determine the early sex in turkeys by observation of the differences in body weight between male and female birds. A total of 30-day old black color unsexed poults having almost similar body weight at hatching were considered for the experimentation and housed at the Poultry Farm of Bangladesh Agricultural University, Mymensingh-2202, Bangladesh. All birds were reared up to 12 weeks of age under intensive management with supplementation of commercial broiler starter and grower feeds. Birds were reared under similar management conditions. Significantly higher (p<0.01) body weight was attained in male poults (104g/bird) than the female (90g/bird) at the end of 1st week of age. Similarly, at the end of 2nd week of age higher (p<0.01) body weight attained by male poults (198.31g/bird) than the female (162.13g/bird). At the end of 3rd weeks of age male poults attained higher (p<0.01) body weight (307.23g/bird) than the female (251.33g/bird). After 4 weeks of rearing, male turkeys attained significantly higher (p<0.01) live body weight (424.46g/bird) than the female turkeys (347.87g/bird). The weekly average body weight gains of male and female birds were 94.18g/bird and 76.5g/bird, respectively. Thus, the male and female birds were successfully identified on the basis of differences in their body weight. Weekly feed intake for both the male and female birds was also increased with their age. Up to 4 weeks of age, both the male and female poults consumed same amount of feed (753.46g/bird). The FCR of male and female poults differed non-significantly in 1st, 3rd and 4th week. On the contrary, in 2nd week of age the FCR of male poults (1.60) was significantly lower (p<0.01) than female (2.11). Survivability was 100% up to 4th week of age irrespective of sex of the poults. The birds were reared up to 12 weeks of age until to confirm their sex by observation of the phenotypic appearance. Results of the phenotypic observation of male and female birds correspondence hundred percent accuracy with the results obtained in body weight based differences between male and female birds. It is therefore concluded that farmers can identify male or female poults as early as first week of age on the basis of body weight differences. Progressive Agriculture 31 (3): 218-226, 2020

Poultry farming holds a special place in ensuring the products that the consumers demand, it provides the population with essential food products,such as eggs and meat,that contain vital micro and macronutrients, proteins, lipids, and vitamins. Therefore, the issues of rational, economically feasible feeding of meat poultry, namely broiler chickens, are an urgent task. It is also essential to find effective methods of their application in order to correct the natural resistance and immune and biological reactivity of birds. The purpose of this research is to study the effect of the biological stimulant-Nucleostim on the growth and development of chickens, hematological, and immunological parameters of the blood of birds.This Biostimulant is a purified bovine spleen extract containing at least 1 mg / ml of low molecular weight peptides (nucleotides and nucleosides) formed as a result of autolysis, using dry whey and diatomite as fillers. Onthe application ofNucleostim, the gain in live weight of chickens was increased by 9.7%. At the end of the experiment, the livability of the chicks of the experimental group treated with Nucleostimcame up to 88%, compared with the 72% of the control group. The use of biostimulant had a stimulating effect on the liver of chickens confirmed by the research results presented in the article, as well as contributed to the development of the thymus in the setting of general dystrophy. Thus, it improved chicklivability and increased body weight gain. The biological stimulant-Nucleostim as an adaptogenic, anabolic, and immunostimulatory agent is promising for finding new drugs that improve the health and productivity of poultry.

Наведені результати випробування на 537 курчатах-бройлерах (635 контрольних) в умовах господарства препарату, виготовленого на основі розчину  полтавського бішофіту. У  курчат, яким давали препарат внутрішньо з водою,  порівняно з контролем, була більшою середня жива масса тіла у  43-добовому віці на 50 г, 73-добовому  – на 128 г і 111-добовому – на  103 г. До 43-добового віку загинуло із розрахунку від  початкової загальної кількості 16 (2,9 %) курчат-бройлерів  у дослідній групі і 30 (4,72 %) у контрольній. На контрольних  курчатах-бройлерах, порівняно із дослідними, мали економію на препараті, який не застосовували, і меншій кількості  використаних  кормів, але одержано значно більше збитків   через нижчі прирости живої маси тіла та більшу кількість загиблих. Економічна  вигода  від застосування препарату лише  до 43-добового віку курчат становить 5,8 гривень на  вкладену 1 гривню. Given results of test on 537 chickens-broilers (635 of control) in terms of economy drug produced on the basis of the solution of Poltava bishofit (SPB). Drug was given chickens-broilers of 5-day age group method internally with water in 3 cycles of 24-hour intervals over 7 times in each cycle and 7-day interval between cycles. The chicks, which were given the drug, compared with the control, had a greater average live weight of the body in 43-day age of 50 g, 73-day – 128 g and 111-day – 103 g it shows its positive effect on organisms of chicks up to 2,5 months (time of observations) after the last application in 38-th days of their lives. The drugs based on the SPB will have greater efficiency in the application of the repair chicks and adult hens, i.e. those who live more than 2,5 months. The 43-day age 16 broiler died of the calculation of the initial total number (2,9 %) in experimental group and 30 (4,72 %) in the control. On control broilers, compared with research, savings on the drug, which is not used, and smaller amounts of used feed, but we received much more losses due to lower increases in live body weight and more fatalities. The total value of the economic benefits of the drug only to 43-day age of chicks is 5,8 UAH on each invested 1 UAH.

The authors studied the growth characteristics (morphophysiological indicators) of broilers’ digestive organs when using Pharmatan in the diet at doses of 0.025; 0.05 and 0.075%. For the study, three medium-weight broiler chickens were selected – on a daily basis for the first three days, then on a weekly basis. The mass of the stomach, individual intestines, the mass of internal organs, and the coefficient of growth rate were determined according to Brody. To study the relative growth rate, the simple allometry formula y = axb was used. It has been established that the most intensive growth of the digestive organs is observed in the first week of broiler life and consists in the stimulated growth of the intestine, especially the cecum. Later on, the growth of the digestive organs in birds of the control group increases and becomes equal to or higher than in broilers of the experimental group. In general, for 42 days of the experiment, the growth rate of the organs of the gastrointestinal tract is practically the same in the birds of the experimental and control groups. The parameters of the regression equations indicate significant differences in the growth of individual organs of the digestive tube during the individual development of broilers. In the experimental groups of broilers, almost all intestinal organs grow quite intensively (b = 1.325–1.783) during the first week of raising, with relatively low values of determination coefficients (cecum – R2 = 0.355; jejunum – R2 = 0.745). High morphological values of 7-day-old birds treated with Pharmatan form the basis for growing broilers with a higher live weight.

In order to increase the meat productivity of broiler chickens, increase production volumes and reduce the prime-cost of poultry products, it is necessary not only to ensure balanced feeding and compliance with production technology but also to include in the poultry diet non-traditional additives, biologically active substances that contribute to the normalization of metabolic processes and improve the digestibility of feed nutrients. One of these dietary additives is Betulin extracted from birch bark, which has antioxidant and immunomodulatory properties. In this regard, the purpose of the research was to study the influence of compound feed with the introduction of 2 % feed additive based on a synthetic microspherical nanoporous carbon carrier containing biologically active Betulin in its composition on the productivity of broilers. The results of studies on broiler chickens using compound feed with 2 % feed additive have been presented in the article. It has been found that the feed consumption per 1 kg of live weight gain in poultry of the experimental group have been lower by 9,5 % due to better absorption of nutrients, the live weight of broiler chickens of the experimental group at the age of 42 days was 2625,6 g and it was higher than the control group by 3,68 %. The digestibility of crude protein and fat reached 92,73 and 88,03 %, which exceeded the control group by 1,03 and 3,03 abs.%, respectively. It has been found that the use of compound feed with 2 % of the feed additive with the biologically active substance is of practical importance in connection with the increase in the productivity of broilers and the level of profitability of meat production by 8,2 abs.%.

A total of sixty, 14-day old broiler chickens (Cobb-500) of either sex were used in this study to assess the effects of processed cassava tuber meals (0, 15, 30, and 45 gkg-1) on growth responses, meat yield, and profitability of boilers; rearing from day 14 to day 33 of ages. The experimental diets were iso-caloric and iso-nitrogenous in nature, and were supplied the broilers ad libitum throughout the trial period. Broilers fed on control diet (i.e. exclusion of CTM) achieved higher (P<0.01) body weight, while the broilers offered diets with the highest amount (45 gkg-1) of CTM had the lowest body weight. Increased (P<0.01) feed intake was observed in the treatments of 21 d and 28 days of age when broilers fed diets with the supplementation of CTM, but no significant differences was found among the dietary treatments in the feed consumption of the broilers during 33 day of age. FCR differed significantly (P<.01) throughout the trial period, broilers fed diets without supplementation of CTM had the superior FCR than the others. Mortality was unaffected by all the dietary treatment groups. Moreover, different body parts (feather, head, neck, wing, viscera) and meat yields (thigh, drumstick, breast, back, giblet, dressing) were not influenced by treatments. Live weights were unaffected by all the dietary groups with/without incorporation of cassava tuber meals (CTM) up to day 21 and day 28 of  ages. Statistically significant (P<0.01) decreased live weight was observed among the treatments in 33-day old birds DOI: http://dx.doi.org/10.3329/jesnr.v5i1.11552 J. Environ.

Twenty four Osmanabadi weaned male kids with average live weight of 10.80 kg were divided into four equal groups and fed with WWNSC and salt sprinkled neem leaves for 182 days to study the effect on growth performance and nutrient digestibility. The daily gain in body weight was significantly (Pis less than 0.05) higher in kids fed with salt sprinkled neem leaves individually than kids fed with WWNSC individually and in combination with salt sprinkled neem leaves. The DM, DCP and TDN intake in terms of per cent live body weight was significantly (Pis less than 0.05) higher in kids fed with salt sprinkled neem leaves individually than kids fed with WWNSC individually. Moreover, digestibility (%) of DM, CF and NFE was significantly (P is less than 0.05) higher in kids fed with salt sprinkled neem leaves individually over kids fed with WWNSC individually except CP which was comparable in all treatments groups.

Whole canola/pea (WCP, 1:1 wt/wt) or whole canola/canola meal (WCC, 3:1 wt/wt) were heat-processed using a commercial pellet mill prior to incorporation in broiler starter (0–20 d) and finisher diets (20–40 d). The pelleted blends readily disintegrated in the preparation of the mash diets. Body weight gain of broilers (0–40 d) fed WCP (0, 10, 20, or 30%) or WCC (0, 5, 10, or 15%) declined linearly with level of dietary inclusion (P < 0.01). Feed intake declined curvilinearly (P < 0.01) with both blends, with lower intake most apparent at the higher inclusion levels. Feed/gain increased for broilers fed WCP or WCC (P < 0.01). Overall broiler mortality declined incrementally with inclusion of WCP (P < 0.07) or WCC (P < 0.03) in the diet. Although there was no distinct limitation on the dietary inclusion levels of either blend, the low feed intake with broilers fed 15% WCC indicated that its level should not exceed 10% of the diet.
