“…The current study found that the addition of PC to the diet significantly increased the spleen index of AA+ broilers compared to the control group, and that the increase in thymus and bursa indices did not reach significant levels. This was also similar to the findings of Sjofjan et al ( 24 ) and Gao et al ( 25 ). The main reason might be that the beneficial flora in the probiotic complex multiply in the intestine and constantly synthesized vitamins, amino acids and other beneficial substances, which are indispensable for the growth and development of the animal's immune organs.…”

The aim of the experiment was to investigate the effects of a probiotic complex (PC) consisting of Bacillus subtilis, Clostridium butyricum and Enterococcus faecalis on productive performance, carcass traits, immune organ indices, fecal microbiota counts and noxious gas emissions in AA+ male broilers. Three hundred and sixty 1-day-old AA+ male broilers with similar body weight (44.77 ± 0.25) were randomly divided into 3 treatment groups of 6 replicates each, with 20 broilers in each replicate. The experimental groups consisted of a group fed a basal diet and groups fed basal diet supplemented with 0.1 and 0.2% PC. The results showed that the addition of PC had no significant effect (P > 0.05) on growth performance, and carcass traits of AA+ broilers during the experimental period (1–42 days of age). Dietary addition of PC significantly increased the thymus index of AA+ broilers (P < 0.05), reduced the number of E. coli and Salmonella in feces (P < 0.01) and reduced the concentrations of fecal NH3 and H2S emissions (P < 0.01). Furthermore, birds fed 0.2% PC diet had the highest number of fecal Lactobacillus counts. Results indicate that probiotic complex consisting of Bacillus subtilis, Clostridium butyricum and Enterococcus faecalis enhances immune organ development, reduces the number of E. coli and Salmonella in feces, increases the number of Lactobacillus and reduces NH3 and H2S emissions in feces. This trial provides a theoretical basis for the use of probiotic complexes in broiler production.

“…They are the main components of the micro ora in the gastrointestinal tracts of many animals. Many studies have shown that lactic acid bacteria can stably add value to a variety of animals by improving their immunity (Sjofjan et al 2021), reducing their pathogenic bacteria (Cisneros et al 2021), promoting their feed conversion rates (Yeh et al 2018), improving their growth rates, and reducing their feed:meat ratios. To reduce or eliminate the harm posed by antibiotics to food safety, many experts and scholars have studied lactic acid bacterial preparations to look for alternatives to antibiotics, and have used then in animal feed and for disease prevention, with good results (Gao et al 2022).…”

Purpose The development and utilization of probiotics have many environmental benefits when they are used to replace antibiotics in animal production. In this study, intestinal lactic acid bacteria were isolated from the intestines of Cherry Valley ducks. Probiotic lactic acid bacterial strains were screened for antibacterial activity and tolerance to produce a Lactobacillus spp. mixture. The effects of the compound on the growth performance and intestinal flora of Cherry Valley ducks were studied. Method In this experiment, we isolated and screened lactic acid bacteria from healthy cherry intestine. The dominant lactic acid bacteria were screened by antibacterial test and tolerance test, and then the new probiotic preparation of lactic acid bacteria mixture was prepared by compound culture of lactic acid bacteria. One day old healthy Cherry Valley ducks were divided into two groups. One group was used as the experimental control, and the other group was used to evaluate the new probiotic preparation feeding group of lactic acid bacteria mixture. The 16S rDNA high-throughput sequencing technique was used to analyze the diversity of intestinal microorganisms in Cherry Valley ducks. Result Based on the results of the antibacterial activity and tolerance tests, the highly active strains Lactobacillus casei 1.2435, L. salivarius L621, and L. salivarius L4 from the intestines of Cherry Valley ducks were selected. The optimum ratio of L. casei 1.2435, L. salivarius L621, and L. salivarius L4 was 1:1:2, the amount of inoculum used was 1%, and the fermentation time was 14 h. In vivo experiments showed that compared with the control group, the relative abundances of intestinal Lactobacillus and Blautia were significantly increased in the experimental group fed the lactobacillus compound (P < 0.05); the relative abundances of Parabacteroides, [Ruminococcus]_torques_group, and Enterococcus were significantly reduced (P < 0.05), and the growth and development of the dominant intestinal flora were promoted in the Cherry Valley ducks. Conclusion The optimal proportion of the new probiotic preparation of lactic acid bacteria mixture is L. casei 1.2435, L. salivarius L621, and L. salivarius L4 was 1:1:2. It can promote the growth and development of the dominant intestinal flora of Cherry Valley ducks, and has made an important contribution to the healthy breeding of Cherry Valley ducks.

There are variable results on the effect of cassava on the performance characteristics of broiler chickens. As a result, this meta-analysis was performed to determine the effect of cassava on feed intake, feed conversion ratio (FCR), and average daily gain (ADG) in broiler chickens. A methodical search performed on Google Scholar, Scopus, Web of Science, and PubMed databases as well as individual journals yielded 365 published articles. Out of 365 studies, 23 that met the inclusion criteria were used for the meta-analysis. Outcome measures were pooled using a random-effects model. Results were expressed as standardized mean differences (SMD) at 95% confidence intervals (CIs). Subgroup and meta-regression analyses were used to explore the effects of studied covariates (broiler strain, inclusion level of cassava, number of broilers per replicate, cassava processing methods, and cassava form) on measured outcomes. Results indicated that cassava had a small positive effect on feed intake (SMD = −0.07, 95% CI −0.26, 0.12) and FCR (SMD = 0.14; 95% CI 0.82, 1.746), but a large negative effect on ADG (SMD = −1.67; 95% CI −1.99, −1.35) compared to the controls. Subgroup analysis by cassava form showed that wet fermented cassava peel meal (WFCPM) had a moderate impact on feed intake (SMD = 0.62, 95% CI 0.47, 0.77) and ADG (SMD = 0.66, 95% CI 0.37, 0.95) in broiler chickens compared with the controls. Our results also found improved growth performance in broiler chickens fed cassava at 4–10%. There is evidence of between-study variance, and studied covariates explain most of the sources of heterogeneity. This study concluded that the replacement of maize with 4–10% WFCPM improved growth performance traits in broiler chickens.
