Resumo: | We aimed to characterize the energetic profile of hair sheep (Ovis aries) raised on pasture in a tropical climate country and verify it is influence on productive and reproductive parameters. A total of 68 non-pregnant adult ewes were randomly distributed into four genetic groups (GGs) according to coat color (Red-coated Santa Inês GG – 17, Black-coated Santa Inês GG – 13, White-coated Morada Nova GG – 28 and Red-coated Morada Nova GG – 10). We collected blood samples at the beginning and at the end of the breeding season. The reproductive efficiency of the ewes was evaluated by fertility, prolificacy, lamb survival rate, and lamb body weight at birth and weaning. We performed statistical analyses using the package PROC GLM and the chi-square (χ2) test from SAS software. The genetic group influenced serum glucose and β-hydroxybutyrate concentrations, prolificacy, and lamb body weight. Male lambs were heavier than female lambs at birth and weaning. Twin lambs were lighter at birth and at weaning than were single lambs. The genetic group, lamb birth rank, and sex influenced the lamb body weight at birth and weaning. This study presents important information on the reproductive efficiency of these hair sheep that are relevant to tropical climate countries. The blood parameters found in this research show that there are important metabolic differences between hair sheep in the semi-arid region of Northeast Brazil. Morada Nova sheep with independent white coat color, higher reproductive performance in tropical conditions. |

Un total de 68 ovejas adultas no gestantes se distribuyeron aleatoriamente en cuatro grupos genéticos (GG) según el color del pelaje (Santa Inês GG - 17 con recubrimiento rojo, Santa Inês GG - 13 con recubrimiento negro, Morada Nova GG - 28 con recubrimiento blanco y Morada Nova GG - 10 con revestimiento rojo). Se recogieron muestras de sangre al principio y al final de la temporada reproductiva. La eficiencia reproductiva de las ovejas fue evaluada por fertilidad, prolificidad, tasa de supervivencia y peso corporal del cordero al nacer y al destete. Los análisis estadísticos se realizaron utilizando el paquete PROC GLM y la prueba de chi-cuadrado (χ2) del software SAS. El grupo genético de las ovejas influyó en las concentraciones séricas de glucosa y β-hidroxibutirato, la prolificidad y el peso corporal del cordero. Los corderos machos eran más pesados que las hembras al nacer y al destete. Los corderos gemelos eran más ligeros al nacer y al destete que los corderos solos. El grupo genético, el rango de nacimiento del cordero y el sexo influyeron en el peso corporal del cordero al nacer y al destete. Este estudio presenta información importante sobre la eficiencia reproductiva de estas ovejas de pelo que son relevante para los países de clima tropical. Los parámetros sanguíneos encontrados en esta investigación muestran que existen importantes diferencias metabólicas entre ovejas de pelo en la región semiárida del noreste de Brasil. Oveja Morada Nova con pelaje blanco independiente, mayor rendimiento reproductivo en condiciones tropicales.O objetivo foi caracterizar o perfil energético de ovinos deslanados (Ovis aries), criados em pastagens em país de clima tropical, e verificar a possível influência sobre parâmetros produtivos e reprodutivos. Um total de 68 ovelhas adultas, não prenhes foram distribuídas aleatoriamente em quatro grupos genéticos (GGs), de acordo com a cor da pelagem (Santa Inês - 17 pelagem vermelha, Santa Inês - 13 pelagem preta, Morada Nova - 28 pelagem branca e Morada Nova - 10 pelagem vermelha). As amostras de sangue foram coletadas no início e no final da época de reprodução. A eficiência reprodutiva das ovelhas foi avaliada por fertilidade, prolificidade, taxa de sobrevivência e peso corporal dos cordeiros ao nascer e ao desmame. As análises estatísticas foram realizadas utilizando o pacote PROC GLM e o teste qui-quadrado (χ2) do software SAS. O grupo genético influenciou as concentrações séricas de glicose, β-hidroxibutirato, prolificidade e peso corporal de cordeiros ao nascimento e ao desmame. Os cordeiros machos foram mais pesados que as fêmeas, ao nascimento e ao desmame. Os cordeiros gêmeos foram mais leves ao nascer e ao desmame, em comparação aos cordeiros únicos. O GG, classificação de nascimento e sexo influenciaram o peso corporal do cordeiro ao nascer e ao desmame. Os parâmetros sanguíneos encontrados neste estudo sugerem que existem diferenças metabólicas importantes entre ovelhas deslanadas criadas na região semi-árida do Nordeste do Brasil.
