Effect of Lactobacillus Species Probiotics on Growth Performance of Dual-Purpose Chicken

Abstract

Introduction In-feed probiotics are becoming attractive alternatives to antibiotics in the poultry industry due to the ever-growing strict prohibitions on antibiotic growth promoters (AGP) in animal production. Methods The study was conducted to investigate the effects of Lactobacillus paracaseis sparacasei and Lactobacillus rhamnosus on the growth performance of 120 day-olds randomly selected Sasso dual-purpose chicken. They were divided into four groups with two replicates per group and 15 chicks per replicate. The treatments were T 1 (control), T 2 (supplement diet with 4g probiotic), T 3 (supplement diet with 2g probiotic), T 4 (supplement diet with 1g probiotic). The experimental feeding trials were conducted after two weeks adaptation period. Results The present findings revealed that the chickens supplemented with Lactobacillus species probiotics during the first week of age have shown higher body weight than control ( p < 0.05). The feed intake of week one of T 2 and T 3 were significantly higher ( p < 0.05) than the T 1 (control). However, there was no significant difference ( p > 0.05) in feed intake in the 2 nd , 3 rd , 4 th , and 5 t h weeks of all treatment groups. The present result showed that there was a significant body weight gain ( p < 0.05) in all probiotic fed groups than the control group. The highest body weight gain was observed in chickens found in the T4 treatment group. Whereas the body weight gains significantly higher and improved the feed conversion ( p <0.05) in the T 2 and T 4 than the T 1 (control). However, the feed conversion ratio was significantly influenced by probiotic inclusion in T 3 as compared to the control group. Conclusion Overall, the results suggest that Lactobacillus paracaseis sparacasei and Lactobacillus rhamnosus have a positive effect on the growth performance of broilers.

Novel mono‐ and multi‐strain probiotics supplementation modulates growth, intestinal microflora composition and haemato‐biochemical parameters in broiler chickens

“…In a recent study, dietary supplementation with multi-strains probiotic consisting of Lactobacillus fermentum, L. plantarum, Enterococcus faecium, Pediococcus acidilactici and Saccharomyces cerevisiae significantly improved growth performance, some haemato-biochemical parameters as well as beneficially modulating gut microflora and also ameliorating Pasteurella multocida infection in broilers (Reuben et al, 2021). Similarly, Fesseha et al (2021), Ramlucken et al (2020), Kazemi et al (2019) and Olnood et al (2015a) separately reported the effects of multi-strain probiotics supplementation on growth performance, gut microbiome development and diversity, intestinal morphology, lipid oxidation and pathogens control in broiler chickens.…”

Combating Bovine Mastitis in the Dairy Sector in an Era of Antimicrobial Resistance: Ethno-veterinary Medicinal Option as a Viable Alternative Approach

“…Several studies from around the world have estimated the yearly occurrence of clinical mastitis as 25 to 30 cases per 100 cows ( https://www.fortunebusinessinsights.com/bovine-mastitis-market-103482 ). In an Ethiopian study, the overall mastitis occurrence was reported to be 73.7% (283/384), of which 28.9% (82/283) was of clinical importance and 71.02% (201/283) was of subclinical significance ( 52 ). A Japanese research study stated the prevalent rates of CM and SCM to be 28 and 13%, respectively, while a closely-related margin of 23.6% was reported from an American study ( 53 ).…”

Effect of novel Lactobacillus paracaesi microcapsule on growth performance, gut health and microbiome community of broiler chickens

“…In this study L. paracasei was used as a probiotic strain to encapsulate with polyacrylate resin. L. paracasei is a rod-shaped (bacillus shape) lactic acid bacteria with a width of 2.0 to 4.0 μm and a length of 0.8 to 1.0 μm ( Fesseha et al., 2021 ). It has been found to stimulate the immune system, suppress harmful pathogens ( Zagato et al., 2014 ), and have anti-inflammatory properties ( Nutten et al., 2012 ); thus, it is included in the feed to improve gut health.…”

“…Limited studies on gut health have been carried out in broiler chickens with this species. Moreover, this species has improved growth performance, intestinal microflora, and overall intestinal health in chicken ( Xu et al., 2019 ; Fesseha et al., 2021 ). In this study, we observed encapsulation of L. paracasei with polyacrylate resin improved the health performance of broilers.…”
