“…Hence, the effective use of feed ingredients and additives is essential to enhance chicken production performance. Effective inclusions such as enzymes, probiotics, prebiotics, or unusual products enhance feed utilization (1)(2)(3)(4). After the COVID-19 crisis and dramatic changes in the feed supply, there was a trend to depend on local feed resources to formulate poultry diets to limit imports and overcome lockdown challenges that influenced the agriculture sector (2,(5)(6)(7)(8)(9).…”

This research aimed to study the impact of supplementation of three multi-enzyme levels (0, 0.1, and 0.2% of feed) and two levels of dietary treatments [standard diet (SD) and low-density diet (LDD)] on growth performance, carcass traits, digestibility, and meat quality of broilers from 1 to 38 days of age. A total of 216 1-day-old Arbor Acres broiler chicks were randomly assigned to a factorial experiment (2 × 3) comprising six dietary treatments, each with six replicates and each replicate with six chickens. The results showed that the LDD significantly reduced body weight gain by 5.0%, compared with the SD. Multi-enzymes significantly improved body weight gain and the production index (PI) relative to the SD. The feed conversion ratio was significantly enhanced with increased multi-enzymes from 1 to 21 days. A significant relation between the multi-enzyme concentration and type of dietary treatment was observed in body weight gain and feed conversion ratio from 1 to 21 days of age. Nitrogen-free extract digestibility was significantly increased by using the SD diet compared with using the LDD. Multi-enzyme supplementation improved the digestibility of dry matter, crude protein, crude fiber, and nitrogen-free extract in the LDD. A significant relationship was found between the multi-enzyme concentration and type of dietary treatment on the pancreas, liver, and intestinal length percentages. The meat dry matter concentration was significantly higher in the LDD group than in the SD group. The low-density diet significantly reduced the total revenue compared with the SD, whereas broilers fed the SD recorded significantly higher total revenue and economic efficiency than those fed the LDD. The low-density diet significantly increased economic efficiency compared with the SD. Multi-enzymes significantly increased the total revenue, net revenue, and economic efficiency than the standard set. In conclusion, using multi-enzymes in broiler diets improved body weight gain. The LDD with multi-enzymes showed enhanced body weight gain compared with the SD without multi-enzymes.

This study evaluated the effectiveness of a new probiotic product developed to reduce the effect of Salmonella infections and compared it to the efficacy of commercial probiotics in broiler chicken. Based on the in vitro assessment of the growth characteristics and safety to human health, four bacterial isolates were isolated, characterized, and identified as excellent candidates for the development of commercial probiotic feed additives for poultry. Compatibility and interactions among the four selected strains were investigated. After that, a preliminary study was conducted in which the selected isolates were evaluated individually in vivo with three different methods of application (water, feed, and oral gavage). The cycle included N = 312 chicks, which were divided into 13 groups, including control, distributed into four batteries, with 78 broiler chickens in each battery. There were eight replicates with 24 chicks in each replicate, and the analysis was randomly done in triplicate. The intentional parameters were growth performance, microbial analysis and humoral immune response. The results of the preliminary study assisted in formulating the new probiotic product. Then In vivo evaluations for the newly formulated product were performed with the comparison with two imported commercial products (Alterion and Galli pro fit) used in poultry farms in Kuwait. The second cycle included N = 96 chicks that were divided into four groups, including control. Each group has three replicates and each replicate has eight chicks, and the analysis was randomly done in triplicate. The results showed that although antibiotics were not used, all the growth parameters were similar and sometimes better than the control. The new product inhibited the growth of salmonella as a control and all chickens in different treatment gained a high mass of meat. The statistical analysis showed that no differences were observed in bird weight, weight gain, feed consumption, and feed efficiency between bacterial strains p>0.05. Also, the different probiotic treatments did not affect the total antibody IgM titers significantly in the broilers (P > 0.05). Thus, the newly formulated product was effective in reducing the salmonella.

In invertebrates, the innate immune system protects against a wide range of microbiological infections. Several immunological processes are involved in the interactive immune response between snails and their parasites, including phagocytosis, nitric oxide synthesis, phenol oxidase activity, lysozymes, and lectin formation. The immunological responses connected to the interaction between snails and parasites are discussed in detail in the current research. Understanding the nature of these interactive reactions will enable scientists to explore approaches to eliminate and cure parasitic infections.
