Abstract Background: The present study aimed to explore the effects of dietary chitosan oligosaccharides (COs) on the growth performance and immunity of broiler chickens.Methods: Four test diets were supplemented with different doses of COs (0, 50, 100 and 150 mg/kg) and formulated. Triplicate groups of broiler chickens were fed with one of the diets ad libitum for 6 weeks. Results: After the end of the feeding trials, oral CO administration improved average daily gain; the activities of digestive amylase, lipase and protease; the activities of serum superoxide dismutase and glutathione peroxidase; serum tumor necrosis factor-α, interleukin (IL)-1, IL-2, IgG, IgM and IgA levels; and reduced feed conversion ratio and malondialdehyde level compared with those of the control group. However, a high dose of CO (150 g/kg) did not further increase its efficiency compared with the moderate dose of CO (100 g/kg). Conclusions: Oral CO administration improved the growth performance and immunity of juvenile broiler chickens and could be used as a feed supplement.

The research was conducted to study the effect of feeding broiler chickens on diets containing isomaltooligosaccharides on the growth performance, carcass traits and immune response. 90-one day old broiler chicks were used according to completely randomized two treatment groups and one control, 30 birds each. Birds fed ad-libitum on basal starter and grower-finisher diets for 35 day. Diets of treatment`s groups contained 0.5 g/Kg and 1 g/Kg of Isomaltooligosaccharides, while the control group fed on the basal diets without Isomaltooligosaccharides supplementation. Dietary supplementation of broiler chickens with Isomaltooligosaccharides improved body weight, feed conversion, carcass traits, two lymphoid organs weight and log antibody titer against avian flu vaccine. Most of the highest values were for birds fed low levels of Isomaltooligosaccharides. Feed intake decreases as Isomaltooligosaccharides level increases. Dietary supplementation with Isomaltooligosaccharides did not affect the lipids profile (triglycerides, total cholesterol, LDL and HDL), however the blood VLDL levels decreased with increased levels of Malondialdehyde and Glutathione reductase. Collectively, Dietary supplementation of broiler chickens with 0.5 g/Kg diet of Isomaltooligosaccharides improved growth performance, carcass traits and immune status.

Abstract The effect of Enterococcus faecium CCM7420 (EF) - enterocin-producing and probiotic strain of rabbit origin, Eleutherococcus senticosus extract (ES) and their combination (ES+EF) was determined on selected bacteria in faeces and caecum content, leukocytes phagocytosis, blood biochemistry and growth performance. Ninety-six weaned rabbits were divided into 3 experimental (ES, EF, ES+EF) and control group (CG). The rabbits in the groups ES and EF+ES were fed commercial diet enriched with E. senticosus extract (30 g/100 kg feed), rabbits in groups EF and CG were fed untreated diet. The rabbits in the EF and ES+EF groups were administered with an overnight culture of E. faecium CCM7420 strain (500 μl/animal/day into water, 109 CFU/ml). The treatment period lasted 21 days. The microbiological examinations in faecal samples confirmed the presence of E. faecium CCM7420 strain. In groups EF and ES+EF, the reduction of faecal coliforms, Pseudomonas-like sp., Clostridium-like sp. and S. aureus was recorded. Leucocyte phagocytosis significantly increased in all experimental groups (P<0.0001) compared to CG. The lowest GPx values were measured in the ES+EF group. Higher total protein, triglycerides and calcium concentrations were detected in experimental groups compared to CG. The cholesterol concentration decreased in the ES group. The highest average daily gain was recorded in EF group; in ES+EF the better feed conversion ratio and no mortality was recorded. These results indicated that the dietary supplementation with the E. faecium CCM7420 and E. senticosus extract stimulate the leukocytes phagocytosis and reduces the potential pathogens in rabbits digestive tract without oxidative stress and improve the growth performance.

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.

This study aimed to investigate the effects of Bacillus amyloliquefaciens LFB112 on the growth performance, carcass traits, immune response, and serum biochemical parameters of broiler chickens. A total of 396 1 day old, mixed-sex commercial Ross 308 broilers with similar body weights were allotted into six treatment groups. The assigned groups were the CON group (basal diet with no supplement), AB (antibiotics) group (basal diet + 150 mg of aureomycin/kg), C+M group (basal diet + 5 × 108 CFU/kg B. amyloliquefaciens LFB112 powder with vegetative cells + metabolites), C group (basal diet + 5 × 108 CFU/kg B. amyloliquefaciens LFB112 vegetative cell powder with removed metabolites), M group (basal diet + 5 × 108 CFU/kg B. amyloliquefaciens LFB112 metabolite powder with removed vegetative cells), and CICC group (basal diet + 5 × 108 CFU/kg Bacillus subtilis CICC 20179). Results indicated that chickens in the C+M, C, and M groups had higher body weight (BW) and average daily gain (ADG) (p < 0.05) and lower feed conversion ratio (FCR) (p = 0.02) compared to the CON group. The C+M group showed the lowest abdominal fat rate compared to those in the CON, AB, and CICC groups (p < 0.05). Compared to the CON group, serum IgA and IgG levels in the C+M, C, and M groups significantly increased while declining in the AB group (p < 0.05). B. amyloliquefaciens LFB112 supplementation significantly reduced the serum triglyceride, cholesterol, urea, and creatinine levels, while increasing the serum glucose and total protein (p < 0.05). In conclusion, B. amyloliquefaciens LFB112 significantly improved the growth performance, carcass traits, immunity, and blood chemical indices of broiler chickens and may be used as an efficient broiler feed supplement.

Background and Aim: The rearing of quails can have a stronger attraction for the breeders if we lower the cost prices by introducing by-products in their feed formulas. The aim of this study was to evaluate the effects of the partial substitution of soybean meal by apricot kernel cake (AKC) in the diet of quails, applied either sequentially or during all phases of rearing, on their growth performances, carcass characteristics, and meat physicochemical composition. Materials and Methods: A total of 600 one-day-old quails (Coturnix coturnix japonica), with equal sex ratio and weighing on average 7±0.2 g, were randomly distributed in one control group and three experimental groups, the latter being designed according to the rate of application of AKC in either sequential or non-sequential mode in different rearing phases. Each group was divided into five replicates of 30 quails, randomly distributed according to either substitution rate of soybean meal by the AKC (0%, 10%, 20%, or 30%) or farming phase. Results: The average daily gain from the 1st to 45th days (average daily gain1–45d) was found to be the highest (4.24 g/d/subject, p=0.021) for the 30% AKC-supplemented feed lot in either starter or finish incorporation (DFTAA), having an optimum final live weight of 193.4 g (p=0.028), a lowest feed conversion ratio of 3.08 (p=0.001), and a daily feed intake of 860 g (p=0.01). Carcass yield was recorded the highest (74.4%, p=0.02) with an optimum meat protein level (30.6%, p=0.024) and the lowest fat content (2.26%, p=0.001) for the same group as well. Conclusion: The partial substitution of soybean meal by AKC in the quails' fattening feeding, during the finishing phase and for all rearing phases, led to a better growth performance, a better carcass yield, and an improved chemical composition of meat.

Cecal Microbiota

Probiotics can promote the health and growth performance of animals through modulation of intestinal microbiota. When used as a feed additive, they have the potential to minimize or abolish the use of antibiotics. In this study, we investigated the effect of the probiotic strain Bacillus amyloliquefaciens TL on the growth performance and cecum microflora composition in Cobb 500 broiler chickens. In total, 180 broilers were randomly divided into three groups—each group comprised 4 pens, and each pen contained 15 chickens. The three groups were fed either a control diet, or a diet supplemented with either the antibiotic chlortetracycline or B. amyloliquefaciens TL. Broilers were weighed, and cecum contents were collected on days 7, 14, 21, and 35, respectively. The broilers in both the antibiotic and probiotic groups exhibited significant weight gain compared with controls, exhibiting increases of 16.02% and 13.40%, respectively, after 35 days (P<0.01). Similarly, the feed conversion ratio (FCR, 1–35 days) of broilers in the chlortetracycline and B. amyloliquefaciens TL groups was lower than that of the controls. HiSeq high-throughput sequencing of 16S rRNA of the cecal microbiota was performed on days 7, 14, 21, and 35, respectively. The Firmicutes/Bacteroidetes ratio was higher in the chlortetracycline and B. amyloliquefaciens TL groups than in the control group on days 14, 21, and 35, and especially on day 21. The prevalence of genera Oscillospira, Ruminococcus, Butyricicoccus, and Faecalibacterium (Firmicutes) was higher in the antibiotic and probiotic groups, while that of Bacteroides, Parabacteroides (Bacteroidetes), and Lactobacillus was higher in the control group. In this study, the changes in the microbiota of the probiotic group were similar to those in the antibiotic group. These results suggest that the probiotic strain B. amyloliquefaciens TL can modulate the cecal microbiota of broilers similar to chlortetracycline.

To investigate the effect of lipopolysaccharides (LPS) on the growth performance, nitrogen metabolism and immunity in preruminant calves, forty Chinese Holstein male calves were randomly divided into two groups and injected intraperitoneally with 2.5 mg/kg BW of sterile saline or E. coli LPS (Escherichia coli O55:b55) on day 24, 26, and 28. The LPS challenge decreased average daily gain and feed conversion efficiency compared with control group (p less than0.05). The urinary concentration of nitrogen (pless than0.05) increased, whereas the nitrogen retention decreased (pless than0.05) after LPS-challenge. Injection of LPS increased body temperature, serum concentration of IL-1, TNF-a, IL-2 and IgG of calves. In conclusion, LPS-challenge activated immune responses, decreased utilization efficiency of nitrogen, and negatively impacted growth performance of preruminant calves.

Hepatic Histopathology

Mycotoxins are toxic secondary metabolites produced by different strains of fungi, such as aspergillus, fusarium, and penicillium that can contaminate feed ingredients or the entire feed of poultry and animals. Mycotoxins can cause many serious complications to both humans and animals due to carcinogenic, mutagenic, and immunosuppressive disorders. Therefore, the present experiment aims to investigate the effect of broiler chickens’ diets supplemented with different levels of nanosilica (NS) as an adsorbent agent of mycotoxins on their growth performance and hepatic histopathology. Detectable levels of toxins were present in the feed before feeding, and all levels of mycotoxins were above the normal limit. A total of 180 one-day-old male Arbor Acres broiler chickens were allocated randomly to six treatment groups with three replicates per group, including ten chickens per replicate. The experiment lasted for five weeks, and dietary treatments included control diet and diets with four levels of nanosilica as 0.05%, 0.10%, 0.15%, and 0.20% as well as 0.50% bentonite (fixfin® Dry) diet. Bodyweight, body weight gain, average daily feed intake, and feed conversion ratio were measured weekly. At the end of the fifth week, six chickens per treatment were sacrificed to investigate the effects of NS and bentonite on carcass characteristics and hepatic histopathology. The results showed that providing broiler chickens’ diets with an adsorbent agent, such as NS or bentonite, can reduce the side effects of mycotoxins and enhance their growth performance. The best record was achieved with NS at 0.20%, compared with the control group and other dietary treatment groups. Accordingly, 0.20% of NS could be used in broiler chickens’ diets to minimize the harmful effects of mycotoxins.

A study of the effectiveness of the use of feed additive Liaform in relation to its effect on the growth and development of broiler chickens. For research, 2 groups of broiler chickens of 55 heads (control and experimental) from 8 days of age were formed on the principle of analogues. Feeding of the control group was carried out with standard complete feed. Feeding of the experimental group was carried out with standard complete feed, in which the feed additive Liaform was added at the rate of 2 g / kg. During the experiment, the general condition of the bird, the safety of the bird, zootechnical and hematological parameters were monitored. It is established that the studied feed additive has a positive effect on the productivity of broiler chickens, improves feed absorption. As a result of the use of feed additive Liaform live weight of broiler chickens in the experimental group was 4.3 % higher compared to the control. The average daily gain of chickens in the experimental group exceeded this figure of chickens in the control group by 4,1 %. The use of feed additives helped to increase feed conversion. The use of Liaform feed increased the protein level in poultry meat

Background: This study was conducted to evaluate the effect of dietary LJP supplementation on growth performance, heat stress resistance and immune status of weaned piglets raised in a high-temperature environment (34 ± 3°C).Methods: A total of 72 Barkshire × Licha Black crossbred piglets were weaned at 30 days of age (BW, 5.88 ± 0.16 kg) and fed either without or with 100, 200 or 400 mg/kg LJP in a completely randomized design, with 3 pens per diet (6 pigs per pen). On day 21, a total of 12 piglets were selected to collect blood samples.Result: The results showed that 200 and 400 mg/kg LJP supplementation decreased the feed conversion ratio (FCR) of piglets compared to the control group (P = 0.037) and dietary LJP linearly increased average daily gain and decreased FCR of piglets (P = 0.037 and 0.011, respectively). In addition, adding 100, 200 and 400 mg/kg LJP reduced the serum HSP70 content compared to the control group (P = 0.019) and dietary LJP linearly and quadratically decreased the serum HSP70 content of piglets (P = 0.030 and 0.011, respectively). Moreover, supplementation of 200 mg/kg and 400 mg/kg LJP increased the serum (NO) and nitric oxide acid phosphatase (ACP) content compared to the control group (P = 0.019; P = 0.003) and dietary LJP linearly increased the serum lysozyme, NO and ACP contents (P = 0.039; P = 0.005; P = 0.001). In conclusion, dietary LJP has potential to regulate systemic defence property of weaned piglets raised in a high temperature condition, accompanied by increased growth performance.
