Influência da suplementação concentrada e da categoria animal no hemograma de ovinos da raça Morada Nova

Abstract: RESUMOObjetivou-se avaliar a influência do nível de suplementação com concentrado sobre o perfil hematológico de ovelhas Morada Nova no terço final da gestação e puerpério, bem como comparar os valores obtidos em diferentes categorias (fêmeas em gestação, puerpério e cordeiros). Utilizaram-se 11 ovelhas, aos 75 últimos dias de gestação e nos primeiros 75 dias de lactação, e oito cordeiros progênie das ovelhas, distribuídas em delineamento inteiramente casualizado em arranjo de parcelas subdivididas no tempo.

“…As for the other parameters of the complete blood count, it is worth pointing out the results related to hemoglobin (HGB), red blood cell count (RBC) and hematocrit (HCT), were all higher in the group with a high BCS and multiple births. For Morada Nova ewes during the postpartum period, Bezerra et al (2013) reported values close to those observed in this study; on average 7.6 ± 1.3 and 9.4 ± 1.2 respectively for HGB and RBC. According to El-Sherif and Assad (2001), in a semiarid environment, erythrocytic parameters increase significantly, reaching maximum values at lambing and decreasing after this period, corresponding to the time with a greater metabolic demand (BEZERRA et al, 2013).…”

Brito et al (2006) in Lacaune ewes and Marino et al (2014) in crossbred ewes did not find variation in the hematological pattern at 7 and 30 days postpartum, and from parturition to 16 days postpartum, respectively.…”

“…Changes in hemoglobin concentrations did not promote drastic changes in the values found for this blood variable, remaining in all reproductive phases within the normality for the specie (Weiss & Wardrop, 2010), probably due to the supplementation offered. According to Bezerra et al (2013), diets deficient in energy are related to low hemoglobin concentrations. However, increased hemoglobin concentrations in the final third of pregnancy in Holstein cows were also reported by Oliveira, Barbosa, Pfeifer, and Cardoso (2003) and Saut and Birgel Junior (2012) in a study with buffaloes.…”

“…Em 1978, Fan e Schons (5) estabeleceram valores para os parâmetros hematológicos de 100 ovinos adultos saudáveis criados a pasto no município de Santa Maria/RS. Desde então, apenas nos últimos 15 anos houve interesse dos pesquisadores na busca pelo estabelecimento de valores de referência em função da idade e fases do ciclo reprodutivo do rebanho ovino brasileiro (6)(7)(8)(9)(10)(11)(12)(13)(14)(15) . Apesar disso, estudos específicos sobre a dinâmica dos parâmetros hematológicos na fase neonatal ainda são raros e muitas vezes os intervalos de referência utilizados na avaliação de cordeiros recém-nascidos ainda são baseados em valores determinados para animais adultos.…”
