Resumo: Abstract: The aim was to assess the effect of the production system on the yield of non-carcass components of Dorper x Santa Inês crossbred lambs. The study was carried out at the teaching and research unit of sheep and goats of the Universidade Tecnológica Federal do Paraná, Campus Dois Vizinhos - PR using 24 uncastrated Dorper x Santa Inês crossbreed lambs (8 animals per treatment). The experimental design was completely randomized using three treatments with eight replicates. The treatments were: Panicum maximum cv. Aruana pasture, no shade, and no concentrate supplementation (PAss); Panicum maximum cv. Aruana pasture in the shade of Louro-Pardo Nativo trees (Cordia trichotoma) and with concentrate supplementation (PAcs); feedlot pens (COp). Carcass weight did not differ between treatments (p > 0.05). However, sheep in feedlot pens showed higher average daily weight gain. The non-carcass components differed significantly (p < 0.05), apart from the empty gastrointestinal tract, respiratory tract, and reproductive organs. Blood and external body components (head, skin, and limbs) showed higher weight in COp animals. The full gastrointestinal tract showed a significant difference between the treatments with the highest weight in sheep in the two pasture systems. Blood yield and weight of liver, kidneys, spleen, and heart were higher in COp animals. The production systems thus affected the total mass of non-carcass components in Dorper x Santa Inês crossbred lambs.

O trabalho foi conduzido na Unidade de Ensino e Pesquisa (UNEPE) de ovinos e caprinos da Universidade Tecnológica Federal do Paraná (UTFPR), Campus Dois Vizinhos – PR. Foram utilizados 24 cordeiros não castrados (8 animais em cada tratamento) provenientes de cruzamento das raças Dorper x Santa Inês. O delineamento experimental foi o inteiramente casualizado, com 3 tratamentos e 8 repetições. Os tratamentos foram: pastagem de Panicum maximum cv. Aruana, sem sombreamento + suplementação alimentar (PAss); pastagem de Panicum maximum cv. Aruana, com sombreamento natural proporcionado pela espécie arbórea Louro-Pardo Nativo (Cordia trichotoma) + suplementação alimentar (PAcs) e confinamento em aprisco (COp). O peso ao abate não apresentou diferença significativa (P < 0,05) entre os tratamentos, já o ganho de peso médio diário teve resultado superior para o confinamento. Os componentes não-carcaça, com exceção do trato gastrointestinal vazio, aparelho respiratório e reprodutor; apresentaram diferenças significativas (P < 0,05) entre os tratamentos. Sangue e os componentes corporais externos (cabeça, pele e extremidade dos membros locomotores) tiveram melhor rendimento nos animais terminados em confinamento. O trato gastrintestinal cheio apresentou diferença significativa (P < 0,05) entre os tratamentos, com valores superiores observados na pastagem de aruana sem sombreamento e com sombreamento (silvipastoril). O rendimento do sangue, fígado, rins, baço e coração foram maiores nos animais terminados em confinamento. Os sistemas de produção estudados influenciaram no rendimento dos componentes não carcaça de cordeiros mestiços Dorper x Santa Inês.UEL2019-05-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3327010.5433/1679-0359.2019v40n3p1215Semina: Ciências Agrárias; Vol. 40 No. 3 (2019); 1215-1224Semina: Ciências Agrárias; v. 40 n. 3 (2019); 1215-12241679-03591676-546Xreponame:Semina.
