“…De acordo com Varanis et al (2021) quanto ao metabolismo energético do sangue, os valores encontrados neste trabalho para as concentrações de colesterol e triglicerídeos encontram-se dentro da normalidade para ovinos. Sousa et al (2020) trabalhando com diferentes suplementações energéticas, também observaram valores de colesterol e triglicerídeos também dentro da referência proposta, com aumento na concentração de colesterol quando utilizado suplemento a base de gordura protegida de palma.…”

“…A concentração de ureia no sangue é proveniente da amônia gerada no ambiente ruminal, oriunda de compostos nitrogenados que não sofreram conversão em proteína microbiana. Quando se tem excesso de amônia no rúmen acarreta sua passagem pela parede ruminal, até a corrente sanguínea, sendo encaminhada para o fígado e transformada em ureia, pelo qual requer de grande aporte energético (SOUSA et al, 2020). Essa ureia pode retornar ao rúmen via saliva ou difusão na parede ruminal e ser eliminada na urina ou no leite, em caso de animais em lactação.…”

“…Essa ureia pode retornar ao rúmen via saliva ou difusão na parede ruminal e ser eliminada na urina ou no leite, em caso de animais em lactação. Além disso, pode representar a incapacidade da fermentação microbiana em relação as fontes de carboidratos em função dos efeitos deletérios do lipídeo (SOUSA et al, 2020). No entanto, à média geral da ureia apresentam-se dentro dos valores de referência, indicando que não houve problemas relacionados ao metabolismo da amônia no rúmen.…”

“…Essa é um metabólito originado a partir da quebra da creatina fosfato que é uma proteína muscular, e sua função é atuar no desempenho dos músculos. Além disso, quando os rins apresentam problemas em sua funcionalidade, os níveis de creatinina no sangue se elevam, então esse metabólico reflete insuficiência renal (SOUSA et al, 2020).…”

“…A proteína sérica total e suas frações são consideradas as informações mais sensíveis, para definir o estado nutricional proteico, de forma que valores baixos contínuos, sugerem consumo proteico inadequado. Como visto, pode-se inferir que o consumo de proteína nesse estudo foi adequado (SOUSA et al, 2020). Na avaliação da proteína total, albumina e ácido úrico não foram observadas diferenças significativas entre os tratamentos, estando à média geral dentro da normalidade.…”

The objective was to estimate the different levels of inclusion of an energetic supplement in the concentrate in relation to consumption and blood biochemistry. The experiment was carried out with lambs with about eight months of age and an average weight of 40Kg. They were distributed in 5x5 Latin square digestibility study cages with five different treatments: 0%, 5%, 10%, 15%, 20% inclusion in the concentrate. The ewes obtained the different levels of energetic supplement in the concentrate with a ten-day adaptation diet and another five days of collection for each animal receiving each treatment on a diet with a roughage concentrate ratio of 50:50. The animals received an average of 3.5% of the live weight of feed. Feces, leftovers of the offered, leftovers of water were collected and the volume and density of urine were measured during the five days of collections for each animal in each phase. Blood was collected three times during the collection days, alternating days, with the first blood collection, on the first day of data collection for each phase, to determine the concentrations of urea, uric acid, creatinine, albumin, total proteins, cholesterol, glucose and triglycerides. The different levels of inclusion of the product in the concentrate did not influence statistically in relation to consumption, there was a statistical difference in relation to the consumption of dry matter in relation to the live weight (DMF) and in relation to the consumption of dry matter in relation to the metabolic weight (DMF), with variation of polynomial regression. It is observed that as the product is included in the concentrate, the faeces tend to soften and, consequently, the amount of water in the faeces increases. Of the blood parameters, no statistical variation was found.

The aim of this study was to evaluate the effect of supplementation during different stages of pregnancy on the development and productive performance of Polwarth sheep. Fifty-three adult ewes under synchronised pregnancy were submitted to a supplement of 1.5% body weight with commercial feed during the different stages of pregnancy on natural pasture: NS - no supplementation, SIG - supplemented during the initial third of pregnancy, SMG - supplemented during the middle third of pregnancy, SFG - supplemented during the final third of pregnancy, and STG - supplemented throughout pregnancy. The ewes were weighed at the time of laparoscopic insemination, at every third stage of the pregnancy, and two days before the expected lambing date, at which time the body condition score and metabolic markers were evaluated. The pre-lambing weight of the STG ewes was greater than that of the SFG and SMG ewes, which were, in turn, greater than the SIG and NS ewes. Body condition was superior in the STG and SFG ewes. Lamb survival was greater in the STG and SFG ewes, and lower in the SMG, SIG and NS ewes. Beta-hydroxybutyrate was lower in the SFG and STG ewes. Supplementation during the final third and throughout pregnancy increases the rates of survival and production in the lambs, with supplementation only during the final third of gestation being less costly for the production system.
