“…Yet, in the research carried out by Feckinghaus (2009), NEFA contents were kept around 280 µmol L -1 (levels close to those found in this research) until the time of the dramatic decrease in temperature (0 °C) when the study was conducted, the changes observed in bloodstream triglycerides contents during the lactation curve are physiological.…”

“…However, considering buffaloes between 65-85 and 95-175 days of lactation, the contents were equal to 3.42 and 3.25 mmol L -1 , respectively (GRASSO et al, 2004), and for buffaloes between 100 and 200 days of lactation, the contents were 3.76 and 3.63 mmol L -1 , submitted or not to treatment with recombinant bovine somatrotopin (rBST) (FECKINGHAUS, 2009). Buffaloes in period equivalent to 91-200 days of lactation recorded glucose contents between 4.0-4.5 mmol L -1 (CAMPANILE et al, 1998).…”

“…The scant information found in the Brazilian literature regarding lipid metabolism in buffaloes (MARQUES et al, 2004;FECKINGHAUS, 2009;VERDURICO, 2010) and, mainly, the lack, in Brazil, of research appropriately planned to assess the influence of inducing factors in the variation of blood profile in these animals, have motivated the elaboration of the present research, which aims to analyze the influence of lactation and dry period in the serum contents of cholesterol, triglycerides, beta-hydroxybutyrate (β-HBO), non-esterified fatty acids (NEFA) and plasma glucose in buffaloes.…”

KEYWORDS Metabolism Lipids Serum Glucose Plasma PALAVRAS-CHAVE Metabolismo Lipídios Soro Glicose Plasma ABSTRACT:The purpose of this study was to analyze the influence of lactation and dry period in the constituents of lipid and glucose metabolism of buffaloes. One hundred fortyseven samples of serum and plasma were collected between November 2009 and July 2010, from properties raising Murrah, Mediterranean and crossbred buffaloes, located in the State of Sao Paulo, Brazil. Biochemical analysis was obtained by determining the contents of serum cholesterol, triglycerides, beta-hydroxybutyrate (β-HBO), non-esterified fatty acids (NEFA) and plasma glucose. Values for arithmetic mean and standard error mean were calculated using the SAS procedure, version 9.2. Tests for normality of residuals and homogeneity of variances were performed using the SAS Guide Data Analysis. Data were analyzed by ANOVA using the SAS procedure Glimmix. The group information (Lactation), Farm and Age were used in the statistical models. Means of groups were compared using Least Square Means (LSMeans) of SAS, where significant difference was observed at P ≤ 0.05. It was possible to conclude that buffaloes during peak lactation need to metabolize body reserves to supplement the lower amounts of bloodstream lipids, when they remain in negative energy balance. In the dry period, there were significant changes in the lipid profile, characterized by decrease of nutritional requirements, with consequent improvement in the general conditions of the animals. RESUMO: Com o objetivo de se analisar a influência da lactação e do período seco nos constituintes do metabolismo lipídico e na glicemia de búfalas leiteiras, foram coletadas amostras de soro e plasma de 147 animais, entre novembro de 2009 e julho de 2010, sendo estes oriundos de propriedades criadoras de búfalos das raças Murrah, Mediterrâneo e Mestiços, localizadas no Estado de São Paulo. A análise bioquímica foi obtida por meio da determinação dos teores séricos de colesterol, triglicérides, ß-hidroxibutirato (ß-HBO), ácidos graxos não esterificados (NEFA) e teores plasmáticos de glicose. Os valores da média aritmética e o erro padrão da média foram calculados utilizando-se o procedimento

“…In our investigation, higher degree of lipolysis in control group of buffaloes may be due to maintain energy supply under climatic stress (lower ambient temperature in winter during experiment). Many researchers also observed cold weather stress may have caused inconstant levels of lipolysis (alike nutritional deficits), and consequently increase in NEFA contents (Feckinghaus, ; Marai and Habeeb, ).…”

Comprehensive information on the role of β-casein and plasminogen-plasmin (PG-PL) system in milk secretion of Murrah buffaloes during winter season is lacking, although effects of cold stress can be ameliorated to an extent by altering microclimate at farm level. Hence, this study was aimed to determine the changes in productivity along with PG-PL system of milk, plasma hormones and metabolites of buffaloes during winter (December-January) season under two different management systems. Average minimum temperature and wind chill index during this season were 7.02 and 12.74 °C respectively. Buffaloes were divided in two groups of six animals each: control and treatment, where treatment group animals were placed in-house with floor bedding of paddy straw and the control group animals in loose housing system without straw bedding. Physiological responses were recorded, and milk and blood samples were collected at weekly intervals for six-week experimental period. Under in-house management system, buffaloes experienced better comfort by alleviating environmental stress as their physiological responses such as respiration rate and pulse rate were significantly reduced (p < 0.01) as compared to the control, which subsequently resulted higher milk yield by 9.92% (p < 0.05). Analysis of milk samples revealed higher concentration of plasminogen (10.6 vs. 8.05 μg/ml; p < 0.01) and β-casein (p < 0.05), and lower plasmin level (0.299 vs. 0.321 μg/ml; p < 0.05) in buffaloes under treatment group. It was also found that plasma cortisol, glucose and non-esterified fatty acids levels were higher (p < 0.01) in control group as compared to the treatment animals by 13.6%, 8.14% and 12.6% respectively. However, milk composition, growth hormone, epinephrine and norepinephrine level in plasma were similar in both the groups. Hence, it may be concluded that provision of in-house shelter management with floor bedding of paddy straw during winter was effective to minimize environmental stress and improved milk production through manipulation of PG-PL system in buffaloes.

RESUMO-Objetivou-se avaliar a produção e composição do leite de búfalas leiteiras tratadas com somatotropina recombinante bovina (rbST) no pico da lactação. Foram utilizadas 18 búfalas adultas distribuídas em dois grupos experimentais. Grupo tratado (rbST): composto por 9 animais que receberam a aplicação de 500 mg de rbST a cada 14 dias, por via subcutânea, totalizando três aplicações. Grupo não tratado (controle): 9 búfalas que não receberam aplicação de rbST. Semanalmente, foi colhida uma amostra de leite para análise e mensurada a produção leiteira de todas as búfalas. As variáveis produtivas e as análises laboratoriais foram avaliadas como medidas repetidas no tempo, referentes aos tempos de colheita dos dados (tempo) de acordo com cada tratamento (rbST e controle). Quando a premissa de esfericidade não foi respeitada (P<0,05), as probabilidades de tempo (P tempo) e das interações dos tratamentos com o tempo (P trat*tempo) foram corrigidas pelo teste de Greenhouse-Geisse Epsilon. A média dos parâmetros estudados, segundo o grupo experimental (tratamento e controle) foi: produção de leite (7,51 e 7,37 kg), gordura (6,12 e 5,94%), proteína (3,82 e 3,66 %), lactose (4,98 e 5,03%), sólidos totais (15,87 e 15,61%), extrato seco desengordurado (7,35 e 7,37%), contagem de células somáticas (411,38 e 237,74 cél/mil/mL), respectivamente. A administração da rbST não influenciou os índices de produção e composição do leite de búfalas tratadas por 28 dias.
