Resumo: We evaluated a new criterion for behavior or reactivity estimation for Saanen dairy goats, based on a ranking of attitude of goats submitted to social isolation from their herd mates. We also evaluated the influence of their behavior on milk production and composition during the whole lactation period and on reproductive characteristics. Twenty-three dairy Saanen goats, aged from 2 to 9 years old, fourteen primiparous and nine multiparous, were divided into two groups according to their reactivity. Non-reactive and reactive animals were allocated in groups one and two, respectively. Milk samples were collected at an interval of 15 days and a ruffian was used to identify the first post-calving estrus. Approximation time showed a mean of 21.42+/-32.70 seconds, which was significantly related to the attitude of the animals. Daily mean of individual milk production was 1.30+/- 0.26 kg, varying from 0.25 to 3.50 kg. Milk yield and composition, besides reproductive attributes, were not significantly affected by reactivity. Reactivity was not affected by parturition. Attitude allowed classification of dairy goats according to their reactivity; however, reactivity did not affect physiological, productive and reproductive attributes of dairy goats.KEYWORDS: behavior; milk production; reproduction; Saanen goats.

Foram utilizadas 23 cabras Saanen, com idade variando de 2 a 9 anos, sendo 14 primíparas e 9 pluríparas, divididas em dois grupos de acordo com a reatividade medida através de escores. No grupo I foram alocados os animais reativos e no grupo II os animais não reativos. Foram realizadas coletas de leite quinzenais e rufiação para identificação do primeiro cio pós-parto. O tempo de aproximação apresentou média de 21,42 ± 32,70 segundos e foi significativamente relacionado com a atitude dos animais. A produção média diária de leite foi de 1,30 ± 0,26 kg de leite/cabra, variando de 0,25 a 3,50 kg. A produção e a composição química do leite e as variáveis reprodutivas não foram afetadas significativamente pela reatividade. Não houve diferença entre primíparas e pluríparas quanto à sua reatividade. O critério de atitude permitiu classificar as cabras conforme a sua reatividade. A reatividade não influenciou as variáveis fisiológicas, produtivas e reprodutivas das cabras leiteiras.Universidade Federal de Goiás2011-09-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionResearchAvaliado por paresPesquisa científicaapplication/force-downloadtext/htmlapplication/pdfhttps://revistas.ufg.br/vet/article/view/459910.5216/cab.v12i3.4599Brazilian Animal Science/ Ciência Animal Brasileira; Vol. 12 No. 3 (2011); 420-426Ciência Animal Brasileira / Brazilian Animal Science; v. 12 n. 3 (2011); 420-4261809-68911518-2797reponame:Ciência animal brasileira (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/vet/article/view/4599/9663https://revistas.ufg.br/vet/article/view/4599/9665https://revistas.ufg.br/vet/article/view/4599/14124Leite, Tisa EchevarriaFischer, Vivianinfo:eu-repo/semantics/openAccess2012-07-01T14:38:07Zoai:ojs.revistas.ufg.br:article/4599Revistahttps://revistas.ufg.br/vetPUBhttps://revistas.ufg.br/vet/oai||revistacab@gmail.com1809-68911518-2797opendoar:2024-05-21T19:55:16.408917Ciência animal brasileira (Online) - Universidade Federal de Goiás (UFG)true
