“…This could be a reason for the differences regarding energy content per kg diet between LC and MYC in the finisher phase. In contrast to the results from the present study, Kraler et al (2015) and Slama et al (2020) reported no effect on performance in their studies with piglets where fibre-rich but nutrient-balanced diets were fed. Furthermore, Schedle et al (2008) demonstrated that moderately increasing TDF contents can lead to increased ADG and ADFI with no difference in G : F. Gutierrez et al (2013) showed that increasing fibre contents and a balanced energy level in the diet did not affect ADFI and ADG; however, there was an improved G : F ratio in growing pigs.…”

“…This can be related to all diets having a physiologically low SDF content in the finisher phase, indicating very low substrate amounts for microbial fermentation. The studies of Kraler et al (2015) and Slama et al (2020) found similar results regarding SCFA concentration when applying nutrient-balanced diets in piglets. Furthermore, the concentration of BCFA increased in a distal direction, irrespective of the diets fed, which is in accordance with Macfarlane et al (1992).…”

The aim of this study was to determine the effect of different sources of fibre in the diets of fattening pigs on performance, feeding behaviour and intestinal physiology. A total of 60 barrows and gilts (initial body weight 28.4 ± 0.4 kg) were allotted to four dietary treatments: control (CON), lignocellulose (LC), mycelium (MYC) and corn gluten feed (CGF). Diets were calculated to provide balanced available nutrient contents. Including MYC in the diet resulted in an increased average daily gain (P < 0.05) compared to CON and CGF, and improved gain to feed ratio (P < 0.05) compared to LC. Pigs in CON (P < 0.05) ate the fewest but largest meals, whereas treatment CGF (P < 0.05) showed the opposite effect, resulting in the same daily feeder occupation time. Regarding intestinal physiology, in ileum, no differences were observed between the contents of short chain fatty acids (SCFA), lactic acid and biogenic amines. In the colon, MYC showed an increased concentration of acetic acid (P < 0.05) as well as the total content of SCFA (P < 0.05), compared to LC and CGF. Distinct fermentation profiles of ammonia were recorded in ileal and colonic digesta, although contents remained below harmful concentrations. Morphometrical measurements showed differences between the fibre sources LC and MYC, as well as LC and the CON in all investigated gut sections. These results provide evidence that the inclusion of specific dietary fibre sources/contents can positively influence the gut morphology and performance of pigs. However, further studies are needed regarding the mode of action and physico-chemical characteristics of the different fibre sources as a precondition for their successful application in pig diets.

“…Lignocellulose, a constituent of plant cell walls, is mainly composed of insoluble NSP cellulose and hemicellulose as well as phenolic lignin ( Liu et al., 2014 ). In the last decade, few studies examined the use of dietary lignocellulose for different farm and companion animals revealing potential effects on digestive physiology and function ( Abad et al., 2013 ; Kröger et al., 2017 ; Slama et al., 2020 ). With respect to poultry nutrition, the feeding of lignocellulose at inclusion levels below 1% could improve broiler performance ( Sarikhan et al., 2010 ; Makivic et al., 2019 ).…”

Effect of feeding different levels of lignocellulose on performance, nutrient digestibility, excreta dry matter, and intestinal microbiota in slow growing broilers

Lignocellulose is a constituent of plant cell walls and might be used as a fiber source in poultry nutrition. The current study investigated the impact of increasing dietary levels of lignocellulose on performance, nutrient digestibility, excreta DM, intestinal microbiota, and bacterial metabolites in slow growing broilers. At an age of 10 wk, 60 male broilers of an intercross line (New Hampshire × White Leghorn) were allocated to cages and fed isoenergetic and isonitrogenous diets containing 0.8% ( LC1 ), 5% ( LC2 ), or 10% ( LC3 ) lignocellulose. After 23 D of feeding, broilers were killed and digesta samples of ileum and excreta analyzed for nutrient digestibility and DM. Cecal contents were analyzed for microbial composition and metabolites. Broiler performance was not affected by feeding dietary lignocellulose. LC3 fed broilers showed reduced ileal digestibility of protein compared to chickens fed LC1 ( P = 0.003). Moreover, increasing levels of dietary lignocellulose reduced apparent digestibility of organic matter and gross energy ( P < 0.001). Feeding of lignocellulose had no impact on the excreta DM of broilers. Increasing levels of dietary lignocellulose lowered cecal counts of Escherichia / Hafnia / Shigella ( P = 0.029) and reduced the total concentration of short-chain fatty acids ( P < 0.001), lactate ( P < 0.05), and ammonia ( P = 0.009). The molar ratio of cecal acetic acid was higher in LC3 fed broilers ( P < 0.001), while the proportions of cecal propionic acid and n-butyric acid were higher in LC1 and LC2 fed chickens ( P < 0.001). Correlation analyses indicated that dietary lignocellulose was negatively related to the total concentration of cecal bacterial metabolites ( P < 0.001). In conclusion, the feeding of lignocellulose did not affect growth performance, but impaired nutrient digestibility of slow growing broilers. While minor changes in cecal microbial composition were detected, cecal bacterial metabolite concentrations were significantly reduced with increasing levels of dietary lignocellulose. These findings suggest that lignocellulose is not extensively degraded by bacteria residing in the large intestine of broilers.

“…The inclusion of 10% WB and pea fiber resulted in increased diamine oxidase activity and expression of transforming growth factor-alpha (TGF-α), trefoil factors and major histocompatibility complex (MHC)-II in the ileum tissues (Chen et al, 2013). The use of 1.5% lignocellulose reduced the cadaverine concentrations in the digesta, but no effects on the expression of immune-relevant genes were found in ileum, spleen, liver, or mesenteric lymph node tissues (Slama et al, 2020). In another study using 5% grape pomace, the expression of some cytokines in the intestinal tissue was down-regulated (IL-1β, IL-8, IL-6, and tumor necrosis factor-alpha (TNF-α)).…”

Dietary fiber (DF) is receiving increasing attention, and its importance in pig nutrition is now acknowledged. Although DF for pigs was frowned upon for a long time because of reductions in energy intake and digestibility of other nutrients, it has become clear that feeding DF to pigs can affect their well-being and health. This review aims to summarize the state of knowledge of studies on DF in pigs, with an emphasis on the underlying mode of action, by considering research using DF in sows as well as suckling and weaned piglets, and fattening pigs. These studies indicate that DF can benefit the digestive tracts and the health of pigs, if certain conditions or restrictions are considered, such as concentration in the feed and fermentability. Besides the chemical composition and the impact on energy and nutrient digestibility, it is also necessary to evaluate the possible physical and physiologic effects on intestinal function and intestinal microbiota, to better understand the relation of DF to animal health and welfare. Future research should be designed to provide a better mechanistic understanding of the physiologic effects of DF in pigs.
