Evaluation of the Effect of Bacillus Subtilis and Pediococcus Acidilactici Mix on Serum Biochemistry, Growth Promotation of Body and Visceral Organs in Lohmann Brown Chicks

Abstract

Recently the use of antibiotic growth promoter (AGPs) in poultry feed is banned in China, leading to the increasing demand for AGPs substitutes. Probiotics have been considered as a potential substitute. The purpose of this study was to evaluate the effects of probiotic on serum biochemistry, and growth promotion of body weight and visceral organs and in Lohmann Brown chicks aged 0 to 9 weeks. Five hundred and forty 1-day-old male chicks were randomly divided into three groups, with six replicates and 30 chicks in each replicate. The experiment was carried out over 70 days. Dietary treatments were: (1) basal diet alone (control group); (2) basal diet containing 0.1% probiotics (probiotic group); and (3) basal diet containing 0.01% zinc bacitracin in the feed (antibiotic group). The body weight (BW) of probiotic group was significantly higher than that of the control group during the whole trial period (p<0.05). ADG (0~70 d) in the probiotic group and the antibiotic group was higher than that in the control group (p<0.05). The Oliver weight and serum total protein (TP) in the probiotic group was higher than that in the control group on the 63rd day (p<0.05). The length of the duodenum, the weight of the spleen, duodenum and Jejunum in both the probiotic and antibiotic groups were higher than those in the control group (p<0.05). The ileum weight in the probiotic group was significantly higher than those in the control group (p<0.05). The ileum length in the probiotic group was significantly longer than that in both the antibiotic and control groups (p<0.05). Probiotic mix with Bacillus subtilis and Pediococcus acidilactici play a similar role in promoting growth of body and visceral organs, and it is a promising growth promoter for Lohmann Brown chicks (0 to 9 weeks).

“…Experimental reports have supported that there are no significant adverse effects caused by probiotic strains of B. subtilis in acute toxicity tests [19,20] or in organs [21], such as the heart and liver, indicating that B. subtilis is safe and non-toxic to mammals [22]. It has also been reported that specific oral serum IgG and intestinal mucosal SIgA, in mice, can be induced by the administration of recombinant B. subtilis spores [23].…”

Probiotic mixture (Bacillus subtilis and Bacillus licheniformis) a potential in‐feed additive to improve broiler production efficiency, nutrient digestibility, caecal microflora, meat quality and to diminish hazardous odour emission

“…Probiotics are new feed additive that could be used instead of antibiotics. Probiotics exert beneficial effects on the body via a range of complicated and interconnected pathways (Yu et al, 2020).…”

“…Probiotics are new feed additive that could be used instead of antibiotics. Probiotics exert beneficial effects on the body via a range of complicated and interconnected pathways (Yu et al, 2020). Production efficiency comprising BWG, FI and FCR are the major parameters used to analyse the economic benefits of poultry production (S. Zhang et al, 2021).…”

Isolamento e caracterização de bactérias com potencial de promoção de crescimento vegetal a partir de cama de aviário

“…O gênero Bacillus também achado em grande abundancia, parece ter origem nos dejetos das aves, uma vez que a administração de probióticos com B. subtillis é amplamente recomendado pelos pesquisadores, substituindo antibióticos e promovendo maior desempenho de crescimento corpóreo e visceral (Ciurescu et al, 2019;Yu et al, 2020).…”
