“…The latency of a bird to right itself during the TI test was 5.50 min (G-C), 4.07 min (G-0.5), and 3.55 min (G-1.0). Previously published results have reported a latency of bird to right itself in the TI test of 2 min for broilers reared in thermalneutral conditions [62]. Similar to our results, Ghareeb et al [62] reported no effect on TI test in broilers fed with a dietary supplement of Lactobacillus sp.…”

The aim of this study was to evaluate the effect of a synbiotic containing a probiotic (Enterococcus faecium, Pediococcus acidilactici, Bifidobacterium animalis, and Lactobacillus reuteri) and a prebiotic (fructooligosaccharides) on fear response, memory assessment, and selected stress indicators in broilers subjected to heat stress. A total of 360 1-day-old Ross 708 chicks were evenly divided among three treatments: a basal diet mixed with a synbiotic at 0 (G-C), 0.5 (G-0.5X), and 1.0 (G-1.0X) g/kg. After 15 d, the broilers were exposed to 32 °C for 9 h daily until 42 d. The object memory test was conducted at 15 day; touch, novel object, and isolation tests were conducted at 35 day; tonic immobility (TI) took place at 41 day. At 42 day, plasma corticosterone and tryptophan concentrations and heterophile/lymphocyte (H/L) ratios were measured. Compared to controls, synbiotic-fed broilers, regardless of concentration, had a shorter latency to make the first vocalization, with higher vocalization rates during the isolation test (p = 0.001). the G-1.0 group had the lowest H/L ratio (p = 0.001), but higher plasma tryptophan concentrations and a greater number of birds could reach the observer during the touch test (p = 0.001 and 0.043, respectively). The current results indicate that the synbiotic can be used as a growth promoter to reduce the fear response and stress state of heat-stressed broilers.

“…The duodenum and jejunum villus height, crypt depth, and villus height-to-crypt depth ratio were not significantly affected by additive supplementation. These results differ from those reported by Garcia et al [6], Awad et al [4], and Baurhoo et al [29], who reported that supplementation with organic acids, a probiotic, and a prebiotic, respectively, significantly influenced intestinal villus height. In some studies, longer villi resulted in better performance [4].…”

“…Inconsistent results have been reported regarding the effects of these additives on broiler growth performance. Although some researchers have shown positive effects on performance of adding probiotics and prebiotics [4,5], others [27,28] have not found positive effects. Numerous factors, such as the environment, manage-ment practices, nutrition, additive type and dosage, and bird characteristics (age, species, stage of production) can affect the response of broilers to feed additives [9].…”

An experiment was conducted to determine the effects of different feed additives on performance, nutrient retention, gut pH, and intestinal morphology of broilers fed different levels of energy. This study was a 4 × 2 factorial arrangement of 4 feed additive programs (a basal diet without any feed additive as the control, the basal diet with added organic acid, the basal diet with added prebiotic, and the basal diet with added probiotic) with recommended levels (3,150 and 3,200 kcal of ME/kg of diet for the starter and finisher diets, respectively) or low levels (90% of recommended) of energy. A total of 640 one-day-old male and female broiler chicks were randomly assigned to 8 treatments. Each treatment consisted of 4 replicate floor pens of 20 birds each. Starter and finisher diets were fed from 1 to 21 d and 21 to 42 d of age, respectively. Dietary levels of other nutrients, housing, and general management practices were similar for all treatments. Dietary inclusion of additives had no significant effects on broiler performance, intestinal villus height, crypt depth, gut pH, and dietary AME. Birds fed the low-energy diets were heavier but had inferior FCR compared with those fed the recommended-energy diets. Prebiotic and organic acid significantly (P < 0.05) improved protein digestibility. The recommended-energy diets significantly (P < 0.05) increased AME and protein digestibility. No interactions were observed for the measured parameters.

“…Numerous studies have demonstrated an improvement in the stress response and overall health of poultry following dietary supplementation with probiotics and synbiotics (Ghareeb et al, 2008 ; Sohail et al, 2010 ; 2011 ; Ashraf et al, 2013 ). Probiotics are live microorganisms that benefit the host by maintaining or restoring the balance of the intestinal bacterial populations (Fuller, 1989 ).…”

Effect of synbiotics on thyroid hormones, intestinal histomorphology, and heat shock protein 70 expression in broiler chickens reared under cyclic heat stress

et al. 2020

This study examined effect of a dietary synbiotic supplement on the concentrations of plasma thyroid hormones, expressions of heat shock protein 70 (HSP70), and intestinal histomorphology in broiler chickens exposed to cyclic heat stress (HS). Three hundred and sixty day old male Ross 708 broiler chicks were randomly distributed among 3 dietary treatments containing a synbiotic (PoultryStar me US ) at 0 (control), 0.5 (0.5×), and 1.0 (1.0×) g/kg. Each treatment contained 8 replicates of 15 birds each housed in floor pens in a temperature and lighting controlled room. Heat stimulation was established from days 15 to 42 at 32°C for 9 h daily. The results indicated that under the HS condition, both synbiotic fed groups had lower liver and hypothalamus HSP70 levels ( P < 0.001) compared to control group; however, HSP70 mRNA expression was not different among treatments ( P > 0.05). There were no treatment effects on the levels of triiodothyronine (T 3 ) and thyroxine (T 4 ) as well as T 3 /T 4 ratio ( P > 0.05). Compared to controls, 1.0× HS broilers had greater villus height in the duodenum ( P < 0.01), and greater villus height and villus height:crypt depth ratios in the ileum ( P < 0.01). There were no differences among treatments on the measured intestinal parameters in the jejunum ( P > 0.05). The results suggest that the synbiotic may ameliorate the negative effects of HS on chicken health as indicated by the changes in the intestinal architecture and the levels of HSP70. Dietary synbiotic supplement could be a feasible nutritive strategy for the poultry industry to improve the health and welfare of chickens when exposed to hot environmental temperature.
