Comparative analysis of body weight and serum biochemistry in broilers supplemented with some selected probiotics and antibiotic growth promoters

Abstract

Objective: The present work was conducted on Cobb-500 broilers fed with either probiotics (Yogurt, Promax ® ) or antibiotic growth promoters (Ciproflox ® , Renamycin ® ) to assess the effects on body weight and biochemical parameters. Materials and methods: A total of 30 day-old broiler chicks were purchased and acclimatized for 7 days in the experimental shed. After initial acclimatization, the broilers were allotted into five equal groups (n=6). Group A was considered as control and was fed commercial ration and fresh drinking water. Groups B and C were fed commercial ration and probiotics (Yogurt, Promax ® ) respectively mixed in water. Groups D and E received commercial ration and antibiotic growth promoters (Ciproflox ® , Renamycin ® ) respectively with water. Body weight of each bird was recorded on day 7, 14, 21, 28 and 35. At the end of trial period, the birds were sacrificed to collect blood in order to prepare serum samples for biochemical analyses considering total cholesterol, triglyceride, high density lipids (HDL), creatinine, alanine aminotransferase (ALT) and aspartate aminotransferase (AST). Results: Body weight in all treatment groups (B, C, D and E) was significantly (P<0.05) higher as compared to control (A) group. Total cholesterol and triglyceride levels significantly (P<0.05) decreased in probiotics treated groups as compared to control and antibiotic growth promoters treated groups. AST and ALT values increased significantly (P<0.05) in antibiotic growth promoters treated groups as compared to control whereas, these values decreased in probiotics treated groups. Creatinine levels were significantly (P<0.05) higher in antibiotic growth promoters treated groups as compared to all others groups. Conclusion: Significantly increased body weight is observed in probiotics and antibiotic growth promoters supplemented broilers. Probiotics also improve the lipid profile and other biochemical parameters as compared to growth promoter. Probiotics (like Yogurt and Promax ® ) seem to be better choice than antibiotic growth promoters as feed supplements.

Dietary probiotics as a strategy for improving growth performance, intestinal efficacy, immunity, and antioxidant capacity of white Pekin ducks fed with different levels of CP

“…However, the elevation of the TP level by increasing the CP level or probiotic addition may indicate an amelioration in duck health ( Hatab et al., 2016 ; Kim et al., 2017 ). Similar results were reported for probiotic addition on blood serum parameters of broilers ( Ashayerizadeh et al., 2011 ; Haque et al., 2017 ; Yazhini et al., 2018 ) and Japanese quails ( Siadati et al., 2017 ).…”

Intestinal Morphologic and Microbiota Responses to Dietary Bacillus spp. in a Broiler Chicken Model

“…In addition, probiotics have positive impacts on colonized beneficial bacterial and growth performance in broilers and pigs (Jeong and Kim, 2014; Valeriano et al, 2017). Noticeably, probiotics, as the alternatives for antibiotics used to prevent poultry diseases and improve production performance, have been demonstrated to be beneficial to chickens’ growth performance and health, such as the increases of body weight (BW), feed conversion efficiency, immune response, resistance to bacterial infection, and regulation of intestinal microflora (Xu et al, 2012; Cao et al, 2013; Song et al, 2014; Clavijo and Flórez, 2017; Haque et al, 2017; Hussain et al, 2017a; Azad et al, 2018; Mashayekhi et al, 2018).…”

“…including Bacillus subtilis, B. coagulans , and B. licheniformis etc. have been widely used as commercialized probiotic products for humans and animals (Barbosa et al, 2005; Zhang et al, 2013; Park and Kim, 2014; Haque et al, 2017; Xu et al, 2017). Bacillus spp.…”

Studies on Serum Mineral Profile and Kidney Function of Broiler Chickens Fed Diets Containing Different Supplements

“…The results of the present experiment with respect to kidney function parameters were in accordance with the findings of Hajati et al (2009) who noted significant decrease (P<0.05) in uric acid level in broilers fed diet supplemented with enzymes. Salim et al (2011), Okuneye et al (2016) and Haque et al (2017) Probiotic microorganisms have the ability to use creatinine, urea, uric acid, BUN and other toxic chemicals as their nutrients for growth. This might be the reason for low creatinine, urea, and uric acid and BUN levels in the present experiment.…”
