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.

Abstract Moringa oleifera (MO) is a widely used as the nutritious and non-traditional feed supplementation containing kinds of bioactive substances. However, the enhancement effect of Moringa oleifera leaf Polysaccharide (MOLP) as a feed additive in broilers growth performance and immunity remains unclear. In this study, MOLP was obtained by water extraction and alcohol precipitation method, then purified with Trichloroacetic acid (TCA) assay. Chickens were randomly divided into 4 groups, to receive different doses of MOLP (0, 0.1, 0.2, 0.4g/kg) in feed for 3 weeks. The body weight gain (BWG) and feed consumption were recorded for feed conversion ratio (FCR) and average daily feed intake (ADFI) calculation. Broiler chickens were sacrificed and sampled on day 14, 21, 28 (D 14, D 21, and D 28) respectively. Serological indicators, including total protein (TP), albumin (ALB), globulin (GLO), and creatinine (CREA) were detected. ELISA kits were applied for detecting the levels of immunoglobulin A (IgA), immunoglobulin G (IgG), interleukin-2 (IL-2), and tumor necrosis factor (TNF-α). From D 21 to D 28, the results showed that middle dose of MOLP significantly increased BWG and ADFI as well as liver and bursa indexes when compared with the control group. In addition, TP and GLO were also increased (P<0.05). All MOLP treatments enhanced the serum concentrations of IgG and IL-2 (P<0.01). Furthermore, results of quantitative RT-PCR showed that high dose of MOLP treatment significantly increased (P<0.001) the mRNA expression levels of IL-2 and TNF-α of chickens relative to the control group. In conclusion, the results showed that MOLP supplementation contributed to improve growth performance and immune response in broiler chickens, and MOLP could be considered as a promising feed additive.

Abstract Antibiotics have revolutionized the intensive poultry production system as a feed additive by promoting growth, production and meat quality through improving gut health and reduction of sub-clinical infections during last five decades. However, currently, the usage of antibiotics in poultry production is under severe scientific and public scrutiny, because antibiotic growth promoter (AGP) has been linked to the possible development of antibiotic-resistant pathogens, which may pose a threat to human health. After European Union ban on in feed antibiotics as growth promoter in poultry, since 2006, prebiotics offer a potential substitute to in feed antibiotics. In this effort, the objective of this present study was to investigate the potentiality of prebiotics (mannan oligosaccharides-MOS and fructo-oligosaccharides-FOS) in replacement of antibiotic growth promoter and their relationship with physio-biochemical indices, antioxidant and oxidative stability and carcass traits of broiler chickens meat. 240 day-old broiler chicks (1 d) of uniform body weight were divided into 30 replicate groups having 8 birds in each. Six corn based dietary treatments were formulated viz. T1 (control diet), T2 (T1 + Bacitracin methylene di-salicylate @ 20 mg/kg diet), T3 (T1 + 0.1% MOS), T4 (T1 + 0.2% MOS), T5 (T1 + 0.1% FOS), and T6 (T1 + 0.2% FOS). Significant (P<0.05) increase in cut up part yields (%) and reduction in cholesterol and fat content in T4 (0.2 % MOS) group. The water holding capacity (WHC) and extract release volume (ERV) were increase (P<0.05) in 0.1 or 0.2 % MOS supplemented group. DPPH (1, 1-diphenyl-2-picrylhydrazy) was higher (P<0.05) and lipid oxidation (free fatty acid and thio-barbituric acid reactive substances) was lower (P<0.05) in T4 group. The standard plate count (SPC), staphylococcus and coliform counts were decreased (P<0.05) in T3 or T4 group. Thus, it can be concluded that mannan oligosaccharides (MOS) may be incorporated at 0.2% level in diet for improved physio-biochemical indices, antioxidant and oxidative stability and carcass characteristics of broiler chickens meat and it may be suitable replacer of antibiotic growth promoter.

The study determined the effect of three different levels of Boswellia serrata tree resin (BSR) supplementation in diets for broiler chickens on the growth performance, selected slaughter analysis, nutrient digestibility, as well as haematology, biochemical and some humoral immunity blood parameters. In total, 200 1-day-old broiler chickens were assigned randomly to four treatments. The broiler chickens were fed diets containing 0 (C), 1.5 (BSR1.5), 2 (BSR2), or 2.5% Boswellia serrata resin (BSR2.5). The BSR treatments improved (P < 0.05) the feed intake and feed conversion ratio at breeding Days 22–35, but did not differentiate the nutrient digestibility in the diets. The best-quality carcass with a high proportion of muscles and low fat content (Control versus BSR diets, linear, P < 0.05) was obtained in broiler chickens fed diets supplemented with 2% and 2.5% BSR. The blood profile was affected by the BSR treatments. The lymphocyte count increased linearly in blood (P < 0.05) along the increasing amounts of BSR. The content of uric acid and aspartate aminotransferase activity in blood plasma decreased upon the BSR supplementation (Control vs BSR diets, linear, P < 0.05; and Control vs BSR diets, linear, P < 0.01, respectively). The resin of Boswellia serrata can be considered as a good botanical feed additive, which can have positive effects on the performance and health of broiler chickens.

Digestive Organs

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.

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.
