Relationship between forage neutral detergent fiber and non-fibrous carbohydrates on ruminal fermentation products and neutral detergent fiber digestibility in goats

Abstract: Background: There is a comprehensive understanding of the role of dietary fiber as a nutrient and its function during digestion in cattle. On the other hand, the role of fiber digestion in goats has not received similar attention. Objective: To evaluate the effects of different ratios of forage neutral detergent fiber (fNDF) and non-fibrous carbohydrates (NFC) on ruminal fermentation products, and in vitro neutral detergent fiber (NDF) digestibility in goats. Methods: A 3 × 5 factorial arrangement in a complet… Show more

“…The NDF content of JA silage (43.9% DM) is lower compared with other silages, such as yellow corn silage (45.0% DM), barley silage (56.3% DM), and oats silage (60.6% DM) ( Table 3 ). High levels of NDF in diets can decrease the consumption of the nonfibrous carbohydrates and the synchronization of energy and nitrogen ( Pinho et al., 2019 ). As shown in Table 4 , the digestible energy and metabolizable energy of JA silage for lactating cows (11.9 and 9.20 MJ/kg DM, respectively) are comparable to those of corn silage (12.5 and 9.75 MJ/kg DM, respectively).…”

“…Moreover, the moisture content of diets, which contained 25 and 30% of spineless cactus, also contributed to the low DMI. Goats prefer less moist and more nutrient-rich feedstuffs, such as grasses, shrub and tree plants, due to their intrinsic selective capacity (Costa et al, 2015;Pinho et al, 2019). The literature reports that in ruminant animals the DMI could also have been physically limited by rumen filling, which is regulated by the proportion of total dietary NDF (Mertens, 1997, Alves et al, 2016.…”

“…According to Pessoa et al (2013), the carbohydrates present in the spineless cactus have high degradation rates, which may favor diet digestibility. The increase in NFC concentration in the diet causes changes in microbial standard in goats gastrointestinal tract, creating an environment favorable for bacterial growth and increased the amount of energy vailable to the rumen microoganisms for multiplication (Ma et al, 2014;Ma et al, 2015;Pinho et al, 2019). This behavior can advantage the digestibility of nutrients.…”

“…La calidad de un forraje está en relación inversa con el contenido de FDN. Un alto nivel de FDN es un indicador negativo de la calidad del forraje (Pinho et al, 2019). La determinación del contenido de fibra en detergente neutro (FDN) en pastos y forrajes involucra el uso de un detergente neutro, lauril sulfato de sodio, que solubiliza pectinas, proteínas, azúcares y lípidos, dejando como residuo las partes fibrosas conformadas por celulosa, hemicelulosas y lignina.…”
