“…However, enzyme addition increased the relative weight of the lymphoid organs (thymus, bursa Fabricius, and spleen) (p<0.05). This finding is in line with other research that showed enzyme supplementation could increase the level of immune defense cells (Montanhini et al, 2013;Cowieson et al, 2016). Additionally, enzymes were found to enhance the immune system by increasing the relative weight of the spleen, thymus, and bursa Fabricius (Attia et al, 2020).…”

Cassava leaves are a potential alternative feed ingredient due to their high levels of crude protein and energy. However, their utilization in poultry feed is constrained by factors such as cyanic acid, fiber content, and nutrient digestibility. This study aimed to investigate the impact of including cassava leaf meal (CLM) as a rice bran substitute and enzyme supplementation on lymphoid organ development and metabolizable energy parameters in broiler chickens. A 2x3 completely randomized factorial design was conducted using 48 Cobb-strain broilers unsexing at 35 days old. The treatments included different levels of CLM and enzyme (NSP and protease) supplementation at a dose of 250 g/ton of feed. The treatments consisted of R0E0: 0% CLM without enzyme, R0E1: 0% CLM with enzyme, R1E0: 1.5% CLM without enzyme, R1E1: 1.5% CLM with enzyme, R2E0: 3% CLM without enzyme, and R2E1: 3% CLM with enzyme. The variables assessed were lymphoid organ development (thymus, bursa Fabricius, and spleen) and metabolizable energy parameters (Apparent Metabolizable Energy (AME), True Metabolizable Energy (TME), Apparent Metabolizable Energy Corrected to Nitrogen (AMEn), and True Metabolizable Energy Corrected to Nitrogen (TMEn)). The data were subjected to analysis of variance (ANOVA) with post-hoc tests conducted for significant differences. Results indicated no interaction between CLM and enzymes in lymphoid organ development and energy metabolizable. The inclusion of CLM led to a reduction in AME and TME (p<0.05). However, enzyme supplementation significantly increased the relative weight of lymphoid organs (thymus, bursa Fabricius, spleen) and metabolizable energy parameters (AME, TME, AMEn, and TMEn) (p<0.05). Importantly, the inclusion of CLM up to a level of 3.0% did not negatively impact the health of broiler chickens. Furthermore, the addition of enzymes effectively mitigated the negative effects associated with CLM inclusion in the feed, suggesting their potential as a strategy to improve feed utilization in broiler production systems.

“…The results of the combination treatment of cassava peel and lactic acid bacteria did not affect the relative weight of the bursa Fabricius. This is under Montanhini et al (2013), giving synbiotics does not always affect, depending on how it is used on livestock. Different strains of probiotic bacteria, a dose of use, and the type of chicken used can give different results.…”

This study aims to evaluate the use of cassava peels added with lactic acid bacteria on the immune organ weight of super native chickens. The material used in this study was 144 Day Old Chick (DOC) super unsex native chicken with an average body weight of 34 ± 3,14 gram. The research design used was a completely randomized design (CRD) with a dose of liquid feed additive in the form of a combination of cassava peel flour and lactic acid bacteria mixed with rations. The treatments in this study included T0: basal ration, T1 (basal ration + 10% feed additive ml/kg), T2 (basal ration + 15% feed additive ml/kg) and T3 (basal ration + 20% feed additive ml/kg). The parameters observed were body weight, the relative weight of lymph, thymus, and bursa Fabricius superficial chicken stock exchange. The result showed that the combination of cassava peel and lactic acid bacteria had no significant effect (P>0.05) on body weight, the relative weight of the lymph organs, thymus, and bursa Fabricius of super native chickens. This research concludes that the combination of cassava peel and lactic acid bacteria as a feed additive can maintain chickens' health by not increasing the relative weight of the super native chicken immune organs to the level of 200 ml/kg.

This study was conducted to evaluate the effects of supplementation of exogenous enzymes in broiler diets that includes fermented canola meal on performance, nutrient digestibility, biochemical indication, antioxidative capacity, digestive enzyme activity, immune responses, and gut health. Five hundred 1-day-old Ross 308 broiler chicks were randomly allocated into five experimental groups (5 replicate/group), the first group: a control (CON) contained a basal diet, and the second to the fifth groups were fed diets as follows: containing 20% canola meal (CM), contains 20% fermented canola meal (FCM), contains 20% canola meal and exogenous enzymes at 0.02%/kg feed (ECM), and contains 20% fermented canola meal and exogenous enzymes at 0.02%/kg feed (EFC), respectively. At the finisher phase, the best body weight gain, feed conversion ratio, and nutrient utilization were associated with chickens fed EFC compared to other groups (P < 0.05). Total protein, albumin, alanine aminotransferase, and superoxide dismutase levels increased (P < 0.05), while cholesterol and malondialdehyde levels decreased in chickens fed on EFC. Likewise, there was a significant increase in the relative weight of the bursa of Fabricius and antibody titer against Newcastle disease, whereas the weight of abdominal fat decreased in the EFC group compared to other groups. Furthermore, there was a significant improvement in the activity of lipase and amylase enzymes (P < 0.05) in the EFC group. Fermented canola meal addition improved gut health (decreased Escherichia coli, increased Lactobacillus, and the highest values of villus height). Overall, these results confirmed that supplementing a fermented canola meal diet with exogenous enzymes improved growth performance through enhancing nutrient digestibility, immunity, antioxidant capacity, and gut health. Thus, adding enzymes to a diet containing fermented canola meal can be recommended as an alternative protein source that could be safely used to replace up to 20% soybean meal in broiler diets.
