Numerous non-antibiotic feed additives (alternatives to antibiotics, ATAs) have been marketed, but few have been evaluated under uniform testing conditions modelling commercial flocks. We compared 24 ATA treatments and the ionophorous coccidiostat narasin against a diet without any feed additives. Feed conversion ratio and body weight gain were registered from day 0 to 28 in Ross 308 chickens housed on litter floor. The chickens were challenged with Eimeria spp., and cecal Clostridium perfringens (CP) counts were investigated. Active components from all ATA classes had a positive impact on intestinal health or production performance. Whereas narasin had a strong CP-reducing effect in combination with performance-promoting impact, only two ATA treatments achieved significantly beneficial effects on CP counts as well as feed conversion during the time span following Eimeria challenge. Active components present in these two treatments include a Bacillus subtilis probiotic strain, short- and medium-chain fatty acids and Saccharomyces cerevisiae components. Different ATA classes had beneficial impact during distinct rearing phases and on specific performance targets, suggesting that optimizing combinations and use of active components can make ATAs even more useful tools in broiler rearing without the use of in-feed antimicrobials. Further studies of promising ATAs and ATA combinations are required.

Intestinal Lesion

Necrotic enteritis (NE) caused by Clostridium perfringens (C. perfringens) results in impaired bird growth performance and increased production costs. Nanotechnology application in the poultry industry to control NE outbreaks is still not completely clarified. Therefore, the efficacy of dietary garlic nano-hydrogel (G-NHG) on broilers growth performance, intestinal integrity, economic returns and its potency to alleviate C. perfringens levels using NE challenge model were addressed. A total of 1200 male broiler chicks (Ross 308) were assigned into six groups; four supplemented with 100, 200, 300 or 400 mg of G-NHG/kg diet and co-challenged with C. perfringens at 21, 22 and 23 d of age and two control groups fed basal diet with or without C. perfringens challenge. Over the total growing period, the 400 mg/kg G-NHG group had the most improved body weight gain and feed conversion efficiency regardless of challenge. Parallel with these results, the mRNA expression of genes encoding digestive enzymes (alpha 2A amylase (AMY2A), pancreatic lipase (PNLIP) and cholecystokinin (CCK)) and intestinal barriers (junctional adhesion molecule-2 (JAM-2), occludin and mucin-2 (Muc-2)) were increased in groups fed G-NHG at higher levels to be nearly similar to those in the unchallenged group. At 14 d post challenge, real-time PCR results revealed that inclusion of G-NHG led to a dose-dependently decrease in the C. perfringens population, thereby decreasing the birds’ intestinal lesion score and mortality rates. Using 400 mg/kg of G-NHG remarkably ameliorated the adverse effects of NE caused by C. perfringens challenge, which contributed to better growth performance of challenged birds with rational economic benefits.

The objective of this study was to evaluate the effects of the dietary supplementation of Bacillus subtilis DSM 32315 (probiotic) on the performance and intestinal microbiota of broiler chickens infected with Clostridium perfringens (CP). One-day-old broiler chickens were assigned to 3 treatments with 8 replicate pens (50 birds/pen). The treatments were: non-infected control; infected control; and infected supplemented with probiotic (1 × 106 CFU/g of feed). On day of hatch, all birds were sprayed with a coccidia vaccine based on the manufacturer recommended dosage. On d 18–20 the infected birds were inoculated with CP via feed. Necrotic enteritis (NE) lesion score was performed on d 21. Digestive tract of 2 birds/pen was collected on d 21 to analyze the ileal and cecal microbiota by 16S rRNA sequencing. Performance was evaluated on d 28 and 42. On d 21, probiotic supplementation reduced (p < 0.001) the severity of NE related lesion versus infected control birds. On d 28, feed efficiency was improved (p < 0.001) in birds supplemented with probiotic versus infected control birds. On d 42, body weight gain (BW gain) and feed conversion ratio (FCR) were improved (p < 0.001) in probiotic supplemented birds versus infected control birds. The diversity, composition and predictive function of the intestinal microbial digesta changed with the infection but the supplementation of probiotic reduced these variations. Therefore, dietary supplementation of Bacillus subtilis DSM 32315 was beneficial in attenuating the negative effects of CP challenge on the performance and intestinal microbiota of broilers chickens.

Backgrounds: Broiler chickens are high productivity livestock. To achieve this productivity, many farmers provide feed additives. Fermented milk is one of the feed additives given through drinking water. Providing feed additives, regularly, will affect the performance of these broilers. Purpose: To investigate the potential of providing fermented milk through drinking water on the performance of broiler chickens. Method: Direct observations and perform calculations on several aspects that support the research. Result: After making observations, it was known that there are differences in the starter phase and the finisher phase. The observation was carried out from the age of 0-27 days. Broiler performance determined by the parameters of feed consumption, chicken body weight, and feed conversion. Conclusion: The observation shows an increase in feed consumption. However, in feed conversion and body weight gain instability is caused by physical conditions, temperature, and palatability in each phase of the broiler chickens.

An immunomodulator is a natural body defence mechanism due to the stimulation of objects/ environments, both specific and non-specific by means of cellular and humoraldefence. The objective of the study was to prove the immunomodulation ability of broiler chickens up to age 35 days that dietary fed various wheat pollard based rations. The design used in the study was a complete randomized design with six treatments and three replications. The treatment of broiler rats consisted of BR-IAJ (T0), control feed with wheat pollard base (T1), control feed with wheat pollard base plus probiotic (T2), wheat pollard based feed steamed (T3), fermented wheat pollard based feed 40% (T4 ) and fermented wheat pollard based feed 60% (T5). The rations used contained 20,5-22,5% protein with 2900-3100 Kcal metabolic energy. Lohman MB 202 Platinum from PT. Japfa Comfeed used in research with average day old chick (DOC) weight of 36,39 + 2,45 g. Parameters observed included body weight, feed intake, feed conversion ratio (FCR), relative weights of liver organ, thymus, lymph and bursa fabricius. The results showed that wheat pollard-based rations had a significant effect (p <0,05) on the relative weight of liver organ, body weight, FCR and ration consumption, but did not affect the relative weights of spleen organ, thymus and bursa fabricius. The mean relative weight of consecutive liver as follows: 2,47 g (T0), 2,83 g (T1), 3,40 g (T2), 2,99 g (T3), 3,15 g (T4) and 3,06 g (T5). The average body weight, consumption and FCR rations were as follows: 1415,24 g; 136,45 g/day; 2,03 (T0), 775,04 g; 125,19 g/day; 3,40 (T1), 813,17 g; 129,86 g / day; 3,36 (T2), 792,89 g; 128,14 g /day; 3,54 (T3), 892,91 g; 138,33 g /day; 3,27 (T4), 969,56 g; 155,52 g/day; 3,37 (T5). The conclusion of the study was that the ration with the addition of wheat pollard 60% was able to provide an increase in body weight gain and the best immunomodulation seen from the aspect of the proportion of immunomodulating organs to the growth of broiler chickens.

The objective of this study was to evaluate the effects of Pediococcus acidilactici (P. acidilactici) and Saccharomyces cerevisiae (S. cerevisiae) on the growth performance, intestinal lesions and ileal Clostridium perfringens (C. perfringens) count of broiler chickens challenged with C. perfringens induced sub-clinical necrotic enteritis (NE). A total of 150 broiler chicks, allocated into five treatment groups (6 replicates of 5 chicks/cage), were reared in cages for 29 days: T0 (control group, not infected, not supplemented); T1 (infected with C. perfringens, not supplemented); T2 (infected with C. perfringens and coccidia, not supplemented); T3 (infected with C. perfringens and coccidia, supplemented with P. acidilactici); T4 (infected with C. perfringens and coccidia, supplemented with S. cerevisiae). The parameters analyzed were: body weight gain, feed intake, feed conversion ratio, mortality, intestinal lesion score and ileal C. perfringens enumeration by quantitative real-time PCR. The challenge resulted in impairment of growth performance, increased lesion score (≤ 2) and overgrowth of the C. perfringens population. However, the dietary inclusion of P. acidilactici or S. cerevisiae caused a significant improvement in feed conversion, net reduction of gut lesions, as well as a decrease in the intestinal C. perfringens population. In conclusion, these results suggest that dietary supplementation with probiotics (P. acidilactici or S. cerevisiae) could be beneficial to alleviate the negative effects of subclinical NE in broiler chickens.

Abstract: The objective of this work was to evaluate the effect of thermal challenge at different intensities and durations on the production responses of 3 to 21-day-old broiler chickens. Two hundred and ten Cobb chicks were subjected to dry-bulb temperatures (tdb) of 27, 30, 33, or 36°C for the duration of 0, 1, 2, 3, or 4 days from the second day of life onwards. The experiment was carried out in four identical environmentally-controlled wind tunnels. Data on body mass (BM), feed intake (FI), and water intake (WI), all in grams, were monitored daily; and body weight gain (BWG), in grams, and feed conversion (FC) were also calculated. The effect of duration was not statistically significant. Empirical models were adjusted to relate BM, FI, and WI with tdb and bird age. The performance of chicks at 21 days of age was analyzed using the BM, FI, WI, BWG, and FC values. Overall, the development of chicks at 33 and 36°C was better than that of those subjected to the lower tdb of 30 and 27°C. The exposure of chicks to cold thermal challenge in early life can have a carry-over negative effect on their production performance up to 21 days of age.

Effective Components

This study was aimed at determining the effective ingredients of yeast culture (YC) for animal breeding. First, the contents of YCs obtained from various fermentation times were detected using gas-chromatography. A total of 85 compounds were identified. Next, 336 Arbor Acres (AA) broilers were randomly divided into seven experimental groups and fed a basal diet, diets supplemented with YCs obtained at various fermentation times, or SZ1 (a commercial YC product). A significant increase in body weight gain (BWG) and a significant decrease in feed conversion ratio (FCR) of AA broiler chicks were observed with YC supplementation. Additionally, most of blood and immunological indices were improved with YC supplementation. According to the production performance and the results of multivariate analysis, glycine, fructose, inositol, galactose, and sucrose were found as the potential effective compounds of YC and were involved in metabolic pathways including glycine, serine, and threonine metabolism. Supplementation with diets based on combinations of effective compounds improved weight gain, feed efficiency, serum immunoglobulin A, and immunoglobulin G, but decreased blood urea concentration. These findings suggest YCs as effective and harmless feed additives with improved nutritional properties for broiler chicks.

This study was carried out to evaluate the production performance, immune response and carcass traits in broiler chickens (0 to 6 weeks) fed diets incorporated with probiotics (Lactobacillus acidophilus and Bifidobacterium bifidi). One-day-old chicks (192) were randomly selected and divided into 24 groups with 8 chicks in each group (6 dietary treatments x4 replicates). Six experimental diets T1, T2, T3, T4, T5 and T6 were formulated to contain an additional 0, BMD @20mg, Lactobacillus acidophilus (106 and 107 cfu/g feed) and Bifidobacterium bifidi (106 and 107 cfu/g feed), respectively. Body weight gain, feed intake, feed conversion ratio and mortality were not (P>0.05) affected by dietary supplementation of probiotics. On 28d of age, antibody responses to inoculated sheep red blood cells were determined. Antibody titres were higher (P less than 0.05) after feeding probiotics (L. acidophilus) supplemented diets (T3 and T4). During 4th week of age, the response to intra-dermally injected phytohaemagglutinin, an index of the in vivo cell-mediated immune response, increased in the groups fed on probiotic (L. acidophilus) supplemented diets. After 6 weeks, the three birds from each treatment group were sacrificed. Relative weights of the bursa of Fabricius and thymus were greater in broiler chickens given the probiotic supplemented diets but there was no effect on carcass traits, cut up parts and relative weights of organs among the dietary treatments. It was concluded that supplementing the diet with probiotic i.e., L. acidophilus (106 cfu/g feed) had a beneficial effect on immune responses but did not affect production performance and carcass traits in broiler chickens.

It is known that necessary to replace the components of organic acids, which are part of acidifiers when drinking water to poultry in order to prevent the adaptation of microbes in the gastrointestinal tract. In the poultry industry organic acids are widely used, which are used as acidifiers to preserve the properties of water consumed. The purpose of this work was to evaluate the efficiency of broiler meat production when using acidifying agents of drinking water Aquasafe and Veleguard. The experimental part of the work has been performed in JSC “Kurinoe Tsarstvo-Bryansk” broiler area “Roshcha” in the Pochepsky district. The object of research was the livestock of broiler chickens cross Cobb 500 at floor housing. The effect of water acidifiers on meat productivity has been studied. Groups of chickens have been formed on the principle of pairs-analogues. Broiler chickens of experimental groups have been separated from the main livestock by a grid in the corner of the room for 100 heads in each group. It has been found by a result of research to be optimal dose usage of acidifying agents water Aquasafe and Veleguard to drink to broiler chickens. The positive effect of these acidifiers on the digestion of crude protein, crude fat, crude fiber, contributing to the effective use of nitrogen, which led to an increase in the intensity of growth, young animals’ livability and improved feed conversion. Slaughter yield in the control group was 55,1 %, and in the experimental group 57,2 and 58,4 %, which was by 2,1 and 3,3 % higher with the same level of metabolic energy and nutrients. In chickens that consumed acidifi ers more intensively used nutrients feed for deposition in the body of the components of the carcass, which affected the production. A positive impact of acidifying agents Aquasafe and Veleguard on meat quality in broiler chickens has been found.
