Resumo: This study aimed to verify the existence of genotype–environment interaction and performance of Santa Inês sheep in confinement and on pasture.  Eighty-two Santa Ines lambs at 75-135 days of age were used. The adaptation period lasted 22 days. Animals were from five different farms, 30 animals were kept on pasture for 112 days and 52 animals were kept in confinement for 85 days. Animals were evaluated on weight gain (WG), body length (BL), thoracic perimeter (TP), hip height (HH), breast height (BH), rib-eye area (REA) and fat thickness (FD) using ultrasound, and scrotal circumference (SC), worm load (FEC) and body condition score (CS). An index (FI) was calculated using the measures taken.  The SAS® software was used for statistical analysis. There was a statistical difference among animals for type of test (confinement or pasture) for WG, REA, FD, SP as well as FI. Measures for animals in confinement were generally higher than for animals on pasture, except for FI and SP. The age at the start of the test did not influence the expression of characteristics. There was no evidence found of a genotype–environment interaction for Santa Ines breed animals in weight gain on pasture and in confinement for the evaluated characteristics.KEYWORDS: fat thickness; index; rib eye area; subjective evaluation; ultrasound.

Foram utilizados oitenta e dois borregos da raça Santa Inês de 75 a 135 dias de idade. O período de adaptação foi 22 dias. Oriundos de cinco fazendas diferentes, 30 animais permaneceram 112 dias a pasto e 52 animais permaneceram 85 dias sob regime de confinamento. As características mensuradas nos animais foram ganho em peso(GP), comprimento do corpo (CC), perímetro torácico (PT), altura da anca (AA), altura do peito (AP), área de olho de lombo (AOL) e espessura de gordura por ultrassom (EG), perímetro escrotal (PE), número ovos/grama de fezes (OPG) e escore corporal (EC).  Um índice (IPGP) foi criado incorporando as características medidas. O software SAS® foi utilizado para as análises estatísticas. Houve diferença entre os animais para o tipo de teste (confinamento ou pasto) para as características GP, AOL, EG, PE e IPGP. Os animais em confinamento apresentaram resultados superiores aos do pasto para as características de ganho em pesoe inferiores para o IPGP e PE.  A idade dos animais no início do teste não mostrou influencia sobre a expressão das características. Não houve evidência de interação genótipo x ambiente para animais da raça Santa Inês nas provas de ganho em pesoa pasto e em confinamento para as características avaliadas.PALAVRAS-CHAVE: área de lombo; avaliação subjetiva; espessura de gordura; índice; ultrassom.Universidade Federal de Goiás2012-06-26info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionResearchAvaliado por paresPesquisa Científicaapplication/pdftext/htmlapplication/downloadhttps://revistas.ufg.br/vet/article/view/565810.5216/cab.v13i2.5658Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 13 No. 2 (2012); 213-220Ciência Animal Brasileira / Brazilian Animal Science; v. 13 n. 2 (2012); 213-2201809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/5658/11152https://revistas.ufg.br/vet/article/view/5658/11153https://revistas.ufg.br/vet/article/view/5658/12494McManus, Concepta MargaretBranquinho, Rosana de PaulaLouvandini, HelderPaiva, Samuel RezendeDallago, Bruno StefanoBertoli, Claúdia Damoinfo:eu-repo/semantics/openAccess2012-06-29T11:47:53Zoai:ojs.revistas.ufg.br:article/5658Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:55:22.536511Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true
