Economicidade E Desempenho Produtivo De Cordeiros Confinados Submetidos a Dietas Com Resíduos Agroindustriais

Abstract

ResumoAvaliou-se o aproveitamento de resíduos agroindustriais na terminação de cordeiros em sistema de confinamento. Utilizaram-se 12 cordeiros, machos, não castrados, da raça Texel, distribuídos aleatoriamente nos tratamentos compostos por diferentes resíduos incluídos na proporção de 30% da matéria seca da dieta total, sendo: casca de soja, quirera de arroz ou pó de malte de cervejaria. Os cordeiros foram confinados por 70 dias e abatidos com aproximadamente 40 kg de peso corporal. Para a análise econômica da alimentação fornecida, foram considerados os preços de mercado obtidos na região do estudo para os ingredientes das rações e peso vivo dos cordeiros. O consumo de carboidratos não fibrosos foi superior (P<0,01) nos cordeiros que receberam quirera de arroz. Não foi verificada diferença em relação ao consumo de matéria seca entre os tratamentos. O ganho de peso diário e o ganho de peso total foram superiores (P<0,05) nos cordeiros que receberam quirera de arroz. O lucro obtido foi superior (P<0,01) quando se utilizou pó de malte de cervejaria (R$ 1,89/kg de ganho de peso vivo) comparado com casca de soja (R$ 0,96/kg de ganho de peso vivo) e quirera de arroz (R$ 1,15/ kg de ganho de peso vivo). A utilização de pó de malte de cervejaria proporciona menor custo de alimentação quando comparada com a utilização de casca de soja ou quirera de arroz, mostrando ser uma boa alternativa para terminação de cordeiros em sistema de confinamento.Palavras-chave: consumo; ganho de peso; ovino; produção animal. AbstractWe evaluated the use of agroindustry residues in finishing lambs in feedlot. Twelve non-castrated male Texel lambs were randomly distributed in the treatments composed of different residues at 30% of dry matter of the total diet, as follows: soybean hulls, broken rice or malt powder from a brewery. The lambs were confined for 70 days and slaughtered at approximately 40 kg body weight. In the economic analysis of the diet, we considered the market prices in the study region for the diet ingredients and weight of lambs. The intake of non-structural carbohydrate was higher (P<0.01) in lambs on the treatment with broken rice. There was no difference between treatments in dry matter consumption. Daily weight gain and total weight gain were higher (P<0.05) in lambs receiving broken rice. Profit was higher (P<0.01) when malt powder from a brewery was used (R$ 1.89/kg of live weight gain) compared with soybean hulls (R$ 0.96/kg of live weight gain) or broken rice (R$ 1.15/kg of live weight gain). The use of malt powder from a brewery provides lower cost of the diet when compared to use of soybean hulls or broken rice, proving to be a good alternative for finishing lambs in feedlot.

Performance and carcass characteristics of Santa Inês lambs fed different protein sources

“…For the variables total weight gain, daily weight gain and feed conversion, no significant differences were observed (Table 3), but the daily weight gains obtained were higher than those recommended by the NRC (2007), of 0.15 kg day -1 , demonstrating that the feed provided enough nutrients to meet the needs of the animals. High values of weight gain in sheep consuming diets containing alternative foods have been reported in research such as rice chirera diets and brewery malt powder (Carvalho et al, 2016), by-products of guava (Silva et al, 2016b), maize grain (Ferreira et al, 2016), ryegrass and legumes (Pellegrin et al, 2018), and orange pomace (Rego et al, 2019), which attribute such results to the high nutritional value of the diets used and the good acceptance by the animals.…”

“…The similarity in feed conversion between diets is related to the better use of nutrients contained in the feed, due to the reduction in the rate of passage of food through the gastrointestinal tract, reinforcing the technical viability of replacing the DSM with FPE. Good feed conversion of sheep consuming peanut pie was reported by Carvalho et al (2016). Sheep may have good carcass characteristics when consuming alternative foods such as soy cake (Grandis et al, 2016), maize residue (Oliveira et al, 2017), orange pomace (Rego et al, 2019), legumes and concentrate (Pellegrin et al, 2018), and grain maize (Ferreira et al, 2016).…”

“…Research carried out using agroindustrial residues in the feeding of small ruminants showed excellent results in animal performance and carcass characteristics, such as soy residue (Grandis et al, 2016), broken rice and brewery malt (Carvalho et al, 2016), guava by-products (Silva et al, 2016b), mazoferm (Oliveira et al, 2017) and orange bagasse (Rego et al, 2019).…”

Análise da gestão do resíduo bagaço de malte em cervejarias da região oeste e extremo oeste do estado de Santa Catarina

“…Quanto à destinação dada ao bagaço de malte, 100% responderam "Alimentação animal". Diversos estudos já demonstraram o potencial de utilização do bagaço de malte para alimentação animal, como cordeiros (BROCHIER; CARVALHO, 2009, GILAVERTE et al, 2011CARVALHO et al, 2016), cabras (SILVA et al, 2010, suínos (ALBUQUERQUE et al, 2011), bovinos (GERON et al, 2008 e frangos (SILVA; FERREIRA, 2017). Reutilizar o bagaço de malte é uma forma de tornar os processos produtivos mais verdes e circulares buscando o perfil sustentável dos novos consumidores (TURCHETTO, 2017).…”

Fruit quality of a traditional pineapple cultivar (Turiaçu) compared to the most popular cultivar (Pérola) in Brazil

“…According to Leonel et al (2014), flours from pineapple residues can be used as sources of insoluble fibers. Moreover, pineapple residues can generate other products, which can have high added values (Carvalho et al, 2016;Lima et al, 2016), such as the use of pineapple peel and crown residues to produce vinegar (Roda et al, 2017) or biofuel (Khedkar et al, 2017).…”
