“…Cardoso et al [ 40 ] found that the dietary supplementation of broilers with 60 mg/kg of piperine increased the absorption surface of the duodenum and the ileum, but higher doses (120 and 180 mg/kg of piperine) caused negative effects, because they decreased absorption surfaces. In the same species, Kanduri et al [ 41 ], Khalaji et al [ 62 ] and Amad et al [ 77 ] reported that a blend of essentials oils, a blend of phytochemicals and a blend of thymol, anethole and cinnamaldehyde, showed the best results in the intestinal micrometry, such as improved villus/crypt ratios. In pigs, Diao et al [ 63 ] reported improvements in intestinal lumen morphology.…”

“…In terms of these characteristics, the use of antibiotic growth promoters (poultry and swine) and animal metabolism modifiers (pigs and cattle) results in an increase in the size of the breast muscle (broilers), an increase in the ribeye area and a decrease in the deposition of subcutaneous fat (mainly pigs and cattle) [ 1 – 3 ]. However, there are few studies with phytochemicals that assess carcass quality characteristics, and based on the literature reviewed, dietary supplementation of broilers with phytochemicals (Biostrong® 505 and 510, Delacon Biotechnik, Steyregg, Austria; thyme and cinnamon extract, clove powder, agronomy extract and lemon balm, essential oil blend) improved quality parameters, including carcass weight, breast weight, and carcass dressing percentage and reduced abdominal fat and relative abdominal fat [ 29 , 41 , 90 , 104 , 122 ]. Other studies reported no changes in these parameters [ 62 , 98 , 102 ], and only two studies analyzed the impact of dietary phytochemicals on carcass parameters in pigs.…”

Dietary inclusion effects of phytochemicals as growth promoters in animal production

et al. 2017

Growth promoters have been widely used as a strategy to improve productivity, and great benefits have been observed throughout the meat production chain. However, the prohibition of growth promoters in several countries, as well as consumer rejection, has led industry and the academy to search for alternatives. For decades, the inclusion of phytochemicals in animal feed has been proposed as a replacement for traditional growth promoters. However, there are many concerns about the application of phytochemicals and their impact on the various links in the meat production chain (productive performance, carcass and meat quality). Therefore, the effects of these feed additives are reviewed in this article, along with their potential safety and consumer benefits, to understand the current state of their use. In summary, the replacement of traditional growth promoters in experiments with broilers yielded benefits in all aspects of the meat production chain, such as improvements in productive performance and carcass and meat quality. Although the effects in pigs have been similar to those observed in broilers, fewer studies have been carried out in pigs, and there is a need to define the types of phytochemicals to be used and the appropriate stages for adding such compounds. In regard to ruminant diets, few studies have been conducted, and their results have been inconclusive. Therefore, it is necessary to propose more in vivo studies to determine other strategies for phytochemical inclusion in the production phases and to select the appropriate types of compounds. It is also necessary to define the variables that will best elucidate the mechanism(s) of action that will enable the future replacement of synthetic growth promoters with phytochemical feed additives.

This study assessed the impact of varying levels of Tectona grandis leafmeal (TGLM) dietary supplementation on the performance of broiler chickens. A basal diet divided into four portions designated diet 1 (the control) and diets 2, 3 and 4 supplemented with 0.2, 0.4 and 0.6%, respectively. One hundred and forty four broiler chicks were randomly assigned to the four experimental diets (36 birds per diet; 9 birds per replicate) using a Completely Randomized Design. At the finisher phase the body weight gain and feed conversion ratio of the birds fed 0.2 and 0.6% TGLM supplemented diets was better (P<0.05) than those fed control diet and 0.4% TGLM supplemented diets. Serum cholesterol concentration was significantly (P<0.05) lower in the birds fed 0.4 and 0.6% TGLM supplemented diets compared to control diet. The catalase concentration in the birds fed 0.4 and 0.6% TGLM supplemented diets were (P<0.05) higher than those birds fed control diet and 0.2% TGLM supplemented diets while the glutathione peroxidase concentration in the birds fed 0.4% TGLM supplemented diets was higher (P<0.05) than those fed control diet, 0.2 and 0.6% TGLM supplemented diet. The lipid peroxidation in the birds fed 0.6% TGLM supplemented diets was (P<0.05) significantly lower compared to the control diet, 0.2% and 0.4% TGLM supplemented diets. The live-weight of the birds fed 0.4 and 0.6% TGLM supplemented diet was higher (P<0.05) than those fed control diet and 0.2% TGLM supplemented diets. The colour score of birds fed 0.4% TGLM supplemented diets was higher (P<0.05) than those fed other diets. The overall acceptability score thigh meat of birds fed 0.4% TGLM supplemented diet was significantly (P<0.05) higher compared to other experimental diets. It was concluded that TGLM supplementation in this study has phytochemicals of health benefits and possess antioxidant properties.

The intestinal gut health is one of the primary determinants of broiler growth and performance. Among the various enteric diseases, necrotic enteritis (NE) is an enterotoxemic disease caused by Clostridium perfringens, which can result in severe economic losses in poultry farming. Antibiotics like bacitracin methylene disalicylate (BMD) and avilamycin (AVL) are commonly used antibiotic growth promoters (AGP) in poultry feed to control necrotic enteritis in birds. Bacillus subtilis PB6 was reported to prevent necrotic enteritis and improve performance in birds. This paper investigated the influence of Bacillus subtilis PB6 in improving the performance of broiler birds in comparison with BMD and avilamycin. A 35 day trial was conducted with 240 day-old commercial broiler chicks (VenCobb 400), which were divided into four treatment groups, where each treatment group was composed of 6 replicates each containing 10 birds, for a total of 60 birds per treatment. The treatment groups included a negative control (no AGP), Bacillus subtilis PB6, BMD, and avilamycin. The parameters analyzed included body weight, feed conversion ratio (FCR), mortality, villus histomorphometry, and European efficiency factor (EEF). Bacillus subtilis PB6 significantly (P < 0.05) improved body weight and FCR (8 points) compared to the control. The group supplemented with B. subtilis PB6 or BMD had higher (P < 0.05) body weight compared to all other treatment groups. The supplementation of B. subtilis PB6 significantly improved the villus height (P < 0.05) compared to control and other AGP groups. The EEF was found to be the highest in the B. subtilis PB6 supplemented group at 35th day as compared to other treatment groups. The combined data from this study indicate that supplementation of B. subtilis PB6 improves overall performance of broilers compared to BMD and avilamycin, and can be used as potential AGP replacement in poultry farming.
