Impact of total substitution of corn for soybean hulls in diets for lambs

Abstract

-The experiment was conducted to assess the effect of substituting corn for soybean hulls on the apparent digestibility of nutrients, carcass performance and characteristics, and yield of cuts of 25 non-castrated male Santa Ines lambs with an initial body weight of 20±2 kg, at approximately 6 months of age, sheltered individually in stalls (1.10 × 1.0 m), considering a totally randomized design, fed 600 g/kg of forage and 400 g/kg of concentrate. Soybean hulls replaced corn at 0, 250, 500, 750, and 1,000 g/kg of dry matter. The intake of dry matter (DM), organic matter (OM), neutral detergent fiber (NDF), acid detergent fiber (ADF), NDF corrected for ash and protein (NDFap), total carbohydrates (TC), non-fibrous carbohydrates (NFC) and total digestible nutrients (TDN) in g/day, and the digestibility of NFC increased linearly with the soybean hull replacement. Crude protein intake displayed a quadratic response, whereas the intake of EE in g/day, the apparent digestibility coefficients of DM, OM, CP, EE, NDF, ADF, NDFap and TC, TDN, average daily gain, carcass characteristics, and yield of cuts were not affected by the soybean hull levels. Soybean hull substitution increased the intake of DM and nutrients, making it possible to replace up to 1,000 g/kg of dry matter in the diets for confined sheep, as it does not compromise performance, digestibility, carcass characteristics, or yield of cuts when used in sheep nutrition.

Soybean hulls inclusion on silage of wet brewery waste

“…Each feedstuff used to produce the silage in this study presented an individual chemical composition similar to those observed in previous studies (Aliyu & Bala, 2011;Bastos et al, 2015;Chanie & FieVez, 2017), where wet brewery waste presented a low dry matter content, and soybean hulls a high dry matter content.…”

“…The use of soybean hulls may cause an effective increasing in the nutrients content of wet brewery waste silage, especially due to soybean hulls may provide an increase in the dry matter. It is important to mention that soybean hulls are a natural energy source for ruminants, replacing the corn, and acting on passage rate and ruminant fermentation (Bastos et al, 2015). For ruminants, soybean hulls have an energy value of 74 to 80% of corn for feedlot animals.…”

“…The soybean hulls present a low lignin content and large proportion of potentially digestible fiber, being very used as primary ingredient in ruminant diets. Many studies have demonstrated the advantages of using soybean hulls as an energy source for ruminants in replacement of corn, as long as it is supplied together with effective fiber sources to reduce the rate of passage and enable ruminant fermentation (Bastos et al, 2015;José Neto et al, 2017;José Neto et al, 2019). Replaces the corn of the ruminant diet with soybean hulls, without changing the quality of animal performance, requires an order of 75%, better digestibility and energy value of the diet, maintaining in certain occasions the economic viability (Alcalde et al, 2009;Gentil et al, 2011).…”

Grape pomace silage on growth performance, carcass, and meat quality attributes of lambs

“…The average LEA value was 13.9 cm 2 , close to the average values of 11.40 and 13.07 cm 2 obtained by Souza Júnior et al ( 2013) in lambs of large and medium frame size kept in feedlot. According to Bastos et al (2015), the average LEA values for Santa Inês lambs are between 9.6 and 14.8 cm 2 . The addition of GPS to the diets showed no significant difference on LEA; thus, carcasses possibly showed similarity of muscularity (Table 6) due to the nonsignificance of diets on the yield and carcass, cuts, and the compactness index (Table 5).…”

Avaliação do efeito da umidade da massa expandida, temperatura e adição de ésteres etílicos como cossolvente do etanol no processo de extração de óleo de soja

“…O farelo de soja pode ser utilizado tanto para ração animal quanto para a alimentação humana, visto que possui alto valor nutricional em proteínas e vitaminas, além de ser um produto hipocolesterolêmico (BASTOS et al, 2015;BITTNER et al, 2013;JOOYANDEH, 2011) As cascas da soja são subprodutos do processo de extração do óleo de soja e representam aproximadamente 7-8% da massa total dos grãos no processo (HAMMOND et al, 2005). Podem ser utilizadas para composição de ração animal, juntamente com o farelo de soja, já que são ricas em fibras (cerca de 83%) (MEDIC;…”
