Resumo: | This work aimed to evaluate the milk production rate and the chemical and physical composition of milk of pure and crossbred Saanen goats in a confinement system raised in tropical climate and to determine the influence on milk production and composition of the genetic group, type of kidding and parturition order. To evaluate the milk production were studied a total of 46 pure and crossbred Saanen with without a defined racial pattern animals - SPRD, being 25 pure Saanen goats, 17 crossed 7/8 Saanen x SPRD and nine 15/16 Saanen x SPRD during the period of november of 2007 to october of 2008. Milk was collected twice a day for the manual method, with a total of 4,362 controls. Data of daily milk production (PDL) was analyzed by the minimum squares method and the total milk production (PTL) and lactation length (DL) was estimated by regression analysis. The PDL was 1.79 Â kg/day, with significant effect (P<0.05) of the genetic group, type of kidding and parturition order. For PTL there was not significant effect of none of the variable study. Crossbred Saanen goats were more production with increase of the degree of blood however, to achieve the degree of blood 15/16, the values of production are similar to pure Saanen goats. The goat milk production increases with the parturition order decreased after the fifth lactation. To evaluate the chemical and physical composition of milk were studied a total of 35 Saanen goats and crossbred Saanen with goats without a defined racial pattern - SPRD, being 16 pure Saanen goats, 12 crossed 7/8 Saanen x SPRD and seven 15/16 Saanen x SPRD. Milk samples were collected twice a day for the manual method, with a total of 1,208 samples. The data of milk composition was estimated by minimum squares method. The means of chemical and physical milk composition was 3.03% for protein, 2.97% for fat, 8.05% for solids non fat, 11.01% for total solids, 1.028g/cm3 for density and 15.25ÂD for acidity with significant effect (P<0.05) of all variables study. ItÂs concluded that the Saanen daily milk production observed in this study was between the average found for this breed and their crossed in Brazil. The milk composition is in accordance with what it determines by the current legislation for chemical and physical composition of goat milk in Brazil being highly variable, influenced by genetic group, type of kidding and parturition order in which the fat content and acidity show the greater variation among the goat milk components in the different genetics groups studied |

Na avaliaÃÃo da produÃÃo de leite foram utilizadas 46 cabras da raÃa Saanen e seus mestiÃos com animais Sem PadrÃo Racial Definido (SPRD), sendo 25 animais puros por cruza, 17 cabras 7/8 Saanen x SPRD e nove cabras 15/16 Saanen x SPRD no perÃodo de novembro de 2007 a outubro de 2008. O leite foi coletado em duas ordenhas diÃrias, pelo mÃtodo manual, perfazendo um total de 4.362 controles. A produÃÃo mÃdia diÃria de leite (PDL) foi estimada pelo mÃtodo dos quadrados mÃnimos e a produÃÃo total de leite (PTL) e duraÃÃo da lactaÃÃo (DL) foram estimadas mediante anÃlise de regressÃo. A PDL geral das cabras foi de 1,79  0,67 kg/dia, havendo efeito significativo (P<0,05) do grupo genÃtico, tipo de parto e ordem de parto. Para PTL nÃo houve efeito significativo de nenhuma das variÃveis estudadas. Cabras mestiÃas Saanen produzem mais à medida que aumenta o grau de sangue sendo que, ao atingirem o grau de sangue 15/16, os valores de produÃÃo sÃo similares aos animais puros por cruza. As cabras aumentam a produÃÃo de leite à medida que se aumenta a ordem de parto decaindo apÃs a quinta lactaÃÃo. Para a avaliaÃÃo da composiÃÃo fÃsico-quÃmica do leite foram utilizadas 35 cabras da raÃa Saanen e seus mestiÃos com animais Sem PadrÃo Racial Definido - SPRD, sendo 16 animais puros por cruza, 12 cabras 7/8 Saanen x SPRD e sete cabras 15/16 Saanen x SPRD no perÃodo de dezembro de 2007 a outubro de 2008. As amostras de leite foram coletadas em duas ordenhas diÃrias pelo mÃtodo manual, perfazendo um total de 1.208 amostras. Os dados da composiÃÃo fÃsico-quÃmica foram analisados pelo mÃtodo dos quadrados mÃnimos. A composiÃÃo mÃdia do leite das cabras foi de 3,03% para proteÃna, 2,97% para gordura, 8,05% para sÃlidos nÃo gordurosos, 11,01% para sÃlidos totais, 1,028g/cm3 para densidade e 15,25ÂD para acidez havendo efeito significativo (P<0,05) de todas as variÃveis estudadas. Conclui-se que a produÃÃo mÃdia de leite diÃria observada neste estudo se apresenta dentro dos padrÃes encontrados para esta raÃa e seus mestiÃos no Brasil. A composiÃÃo fÃsico-quÃmica do leite està de acordo com o que preconiza a legislaÃÃo vigente para o leite de cabra no Brasil, sendo bastante variÃvel e influenciada pelo grupo genÃtico, tipo de parto e ordem de parto, com os teores de gordura e de acidez apresentando a maior variaÃÃo dentre os componentes do leite nos diferentes grupos genÃticos estudadosFundaÃÃo Cearense de Apoio ao Desenvolvimento Cientifico e TecnolÃgicohttp://www.teses.ufc.br/tde_busca/arquivo.php?codArquivo=4385application/pdfinfo:eu-repo/semantics/openAccessporreponame:Biblioteca Digital de Teses e Dissertações da UFCinstname:Universidade Federal do Cearáinstacron:UFC2019-01-21T11:17:27Zmail@mail.com - |
