“…Although no direct effects were observed for villus height and crypt depth separately, a lower VH:CD was observed for the BEM diet when compared with the BXS diet. The BXS diet led to a desirable VH:CD, as longer villi and shallower crypts represent greater nutrient absorption capacity and lower energy expenditure with cell renewal in the intestine, respectively (Souza et al, 2021). This finding may be associated with the mechanisms of action of prebiotics, glucans, β-glucans, and MOS, and constituents of yeast cell wall since both BX and BXM diets did not affect the jejunal epithelium.…”

Non-ruminantsFull-length research article Energy-reduced diets supplemented with xylanase, Bacillus sp., and yeast wall maintain bone parameters, gut morphometry, economic indices, and performance of pigs ABSTRACT -This study aimed to investigate the effects of xylanase (Xyl) individually or in combination with B. subtilis and B. licheniformis associated or not with yeast cell wall in pig diets with a reduction of 100 kcal/kg of metabolizable energy (ME) content. Pig performance, bone parameters, intestinal morphometry, and bioeconomic indices were evaluated. A total of 75 pigs (25 females and 50 barrows; 25.02±3.21 kg) obtained from crossing Large White × Landrace were used. The experimental design consisted of randomized blocks, with five treatments and five blocks, totaling 25 experimental units subjected to treatments: basal diet (B); basal diet with reduction of 100 kcal/kg of ME (BEM); BEM with supplementation of xylanase (0.01%; BX); BX with supplementation of direct-fed microbials (composed of B. subtilis and B. licheniformis; 0.02%; BXM); and BX supplemented with 0.10% of symbiotic (which includes B. subtilis, B. licheniformis, and yeast cell wall; BXS). There were no differences in bone parameters. The BEM diet resulted in a lower villus height:crypt depth ratio in the jejunum than that seen upon using the BXS diet as feed. In the first period, pigs fed BEM diet had a 12% higher average daily feed intake than those fed the BXM diet. There were no differences in the pig performance during the second period. Over the total period, pigs fed BEM diet had greater FCR compared with pigs fed BXM diet. The inclusion of feed additives in diets with reduced ME content contributes to the maintenance of performance and characteristics of the metacarpus and jejunum of growing pigs and provides better bioeconomic indices.

“…The broilers supplied with lemon or orange peel essential oil, either alone or in combination, had signi cantly greater (P < 0.01) body weight and weight gain than the control group [4/]. Souza et al [52] revealed that birds who received the highest dose (400 mg/kg) of orange essential oil had higher bone density and body weight at day 21. The observed effects were due to improved digestion and nutrition absorption physiological mechanisms, as evidenced by an increase in villus height [52].…”

Essential oil with 91.88% limonene extracted from waste Nagpur orange peels using indigenously designed and patented extraction mechanism was used to investigate effect of its supplementation on performance, immune response and gut health in broilers. 300 chicks (VenCobb-430) were distributed in 5 groups having 15 chicks per replicate using completely randomized design. The diet was formulated as per BIS (2007) standards for control, while antibiotic was added in T @ 500g/ton and orange peel essential oil (OPEO) @ 50, 100, 150g/ton were added in T 2 , T 3 and T 4 respectively. The cumulative feed intake, body weights and FCR for overall period was signi cant (P < 0.05). The percent nutrient metabolisability improved numerically and NFE metabolisability was signi cantly higher (P < 0.05) in treatment groups. Carcass characteristics and sensory attributes were not affected (P > 0.05) except gizzard weight. The hematological parameters remained comparable (P > 0.05); while LPO improved signi cantly (P < 0.05) in OPEO supplemented groups. The total protein, albumin, A:G ratio and uric acid remained comparable (P > 0.05); while globulin improved signi cantly (P < 0.05) in OPEO supplemented groups. The serum antibody titre against RD virus, bursa and spleen weight was signi cantly higher (P < 0.05) in T 3 . Morphometry of intestine and liver remained comparable; however, lung morphometry altered signi cantly (P < 0.05). Hence, it is concluded that dietary supplementation of OPEO at 100g/ton improved performance, gut health and immune response of broilers. To the best of our knowledge, this is the rst attempt to evaluate the effect of essential oil extracted from Nagpur orange peels in broilers.
