“…The result conformed to the result of the previous study conducted by Yousefi and Karkoodi (2007) that the body weight changes were not significantly different among treatment groups or was not affected by the dietary probiotic supplementation. Arslan et al (2004) reported too that probiotics had no significant (P≤ 0.05) effect on growth in broilers.…”

Health risk issues caused by antibiotics as growth promoters as well as a change in meat preference to chickens led the exploration for alternatives. The study determined the best kind and level of probiotics to colored chicken in terms of growth performance, carcass quality and economic analysis. One Hundred Sixty Five (165) day-old chicks were randomly distributed into eleven treatments replicated thrice employing RCBD. Comparable performance were observed on colored birds given different probiotics from 10 to 30% levels in terms of growth performance and carcass quality. However, giving the colored birds probiotics at 30% level resulted to a higher cost of feeds to produce a kilogram gain in weight.

“…The Bacillus subtilis DSM17299 bacterial strain used in our experiment was described by Reis et al (2017) as improving performance and reducing production costs [31]. As was demonstrated in our experiment as well, probiotic (Bacillus licheniformis and Bacillus subtilis [32]) or synbiotic (inactivated and live Saccharomyces cerevisiae [33]) treatments do not always improve the performance parameters of broilers significantly. In a recent study, Bacillus subtilis was used in ovo, either in the feed or in the drinking water.…”

In this research, the effects of early post-hatch inoculation of a competitive exclusion product (Br) and the continuous feeding of a synbiotic supplement (Sy) containing probiotic bacteria, yeast, and inulin on the production traits and composition of ileal chymus (IC), ileal mucosa (IM), and caecal chymus (CC) microbiota of broiler chickens were evaluated. The dietary treatments had no significant effects on the pattern of intestinal microbiota or production traits. The digestive tract bacteriota composition was affected mostly by the sampling place and age of birds. The dominant family of IC was Lactobacillaceae, without change with the age. The abundance of the two other major families, Enterococcaceae and Lachnospiraceae decreased with the age of birds. In the IM, Clostridiaceae was the main family in the first three weeks. Its ratio decreased later and Lactobacillaceae became the dominant family. In the CC, Ruminococcaceae and Lachnospiraceae were the main families with decreasing tendency in the age. In IC, Br treatment decreased the abundance of genus Lactobacillus, and both Br and Sy increased the ratio of Enterococcus at day 7. In all gut segments, a negative correlation was found between the IBD antibody titer levels and the ratio of genus Leuconostoc in the first three weeks, and a positive correlation was found in the case of Bifidobacterium, Rombutsia, and Turicibacter between day 21 and 40.

“…Others have shown that adding probiotics to a broiler's diet does not effect on feed conversion rate (FCR) [50]. Furthermore, it was shown that taking probiotic supplements did not affect on weight growth [51].…”

Antibiotic-resistant bacteria have emerged as a result of the sharp rise in the usage of antibiotics as a necessary component of poultry and cattle production. Green tea, which has antioxidant properties, and probiotics, which are living microbial substances, are thought to be suitable alternatives to antibiotics in chicken diets since they have been linked to improved bird development and health. Aims: This study was conducted to investigate the effects of tea extracts and probiotics on the growth performance and carcass yield of broiler chickens. Place and Duration of Study:The experiment was performed at Department of Physiology, Faculty of Veterinary, Animal and Biomedical Sciences,Khulna Agricultural University, Khulna-9100, Bangladesh during the period from January 2023 and April 2023. Methodology: A total of 200 one day old Cobb 500 broiler chicks were randomly allotted to 5 groups (40 chicks in each group). All were kept in cages for a period of 5 weeks. Dietary treatments used in this experiment were antibiotic free group (basal diet as a control), antibiotic-added group, tea extract group, probiotic group and a combination of tea extract and probiotic group. A starter diet from day 1 to 21 and a grower diet from day 22 to 35 were fed. Weekly assessments of growth performance parameters were documented, and on the 35th day, carcass yield were measured. Results:The highest body weight gain was observed significantly (P<0.05) in Group E which was 2200gm in comparison to other groups. Total feed consumed by birds was highest in group D (3360gm) whereas the lowest feed consumed in group B treated by antibiotics (3198gm). Significant differences (P<0.05) were observed among feed consumption of different groups. However, the best feed conversion ratio (FCR) was observed in Group E (1.48) followed by Group D (1.58), Group C (1.60), Group A (1.61) and the worst FCR was recorded in group B (1.64) at 35th days. Among the groups; group E obtained the highest dressed weight followed by D, C and A whereas the lowest dressed weight was reported in B group. Conclusion: Hence, the results suggested that better growth performance could be achieved in broilers supplemented with probiotics and tea extract and these can be used as herbal growth promoter.
