“…Triglycerides remained high during the prepartum period, but showed a sudden drop on the parturition day, maintaining lower values after parturition in both groups (Figure 1e). A similar behavior in the values of this biochemical variable was also observed in the study of Cupertino et al (2011). Unlike our study, Avci and Kizil (2013) verified that the use of an injectable solution of selenium, copper, zinc, and manganese in dairy cows in the transition period decreased the contents of triglycerides.…”

The aim of this study was to assess the metaphylactic effect of subcutaneous doses of trace minerals (copper, zinc, selenium, and manganese) and vitamins A and E on biochemical (NEFA, BHBA, fructosamine, urea, triglycerides, HDL, and calcium) and hormonal parameters (cortisol, insulin, and IGF-1) of Holstein cows in the transition period. Sixty animals kept in a semi-confinement system, with an average production of 22 liters of milk per day (Farm 1) and 24 liters of milk per day (Farm 2) and a diet according to NRC (2001) with a low metabolic challenge, were divided into two groups: a treatment group, supplemented with trace minerals and vitamins (MTVG) (n=30), and a control group (CG) (n=30). The collection of blood samples was performed at the moments M1 (21 days prepartum), M2 (14 days prepartum), M3 (7 days prepartum), M4 (parturition day), M5 (7 days postpartum), M6 (14 days postpartum), and M7 (21 days postpartum). The experimental design was a randomized block design and the data were submitted to analysis of variance with repeated measures in time within the random variable cow. Differences were considered significant at 5% significance level and trend at 10% level. No difference was observed between treatment and the interaction treatment × day in the assessed parameters. However, some variables showed a significant difference of day. NEFA levels (P < 0.0001) were higher on the parturition day. BHBA concentrations were higher after parturition (P=0.0031), with a peak at the third week of lactation. Fructosamine showed increasing values until the parturition day (P=0.0373), in which higher concentrations were observed. Average values of HDL were higher at 21 days postpartum (P < 0.0001). Triglycerides levels remained high during the prepartum period but showed a sudden drop on the parturition day (P < 0.0001), with lower values postpartum. Regarding serum calcium and IGF-1, lower values were observed on the parturition day (P < 0.001) for both parameters. Cortisol presented a difference regarding day, with higher values on the parturition day (P=0.0151). Thus, the use of trace minerals and vitamins A and E in animals with an adequate body score and low metabolic challenge presents a low response to biochemical and hormonal parameters.

“…High-production animals have greater nutritional requirements, and consequently require a balanced and continuous mineral supplement, since problems with these basics can compromise mineral serum levels in the animal's organism. This is confirmed by Cupertino et al (2011), who found a decrease in Mg concentrations, both when the mineral supplement was no longer offered to the cows and when the animals were in a period of greater milk production. As such, it is necessary to emphasise the importance of the current production scenario on the correct management of mineral supplement.…”

“…In this study, the reproductive period of cows has no influence on serum magnesium levels ( Figure 2). These results can be compared to those of Cupertino et al (2011), who evaluated Mg concentrations during the transition period (30 days before and 30 days after calving) and found there to be no significant difference, both in relation to the period of the cows or in relation to the season. The prevention of subclinical hypomagnesemia should be directed at two main objectives: the continuous supply of adequate levels of Mg in the diet and maximising the absorption of this essential mineral, with salt supplements being the most common choice due to the cost and taste (Odette, 2005).…”

In dairy farming, cows display important metabolic changes during the transition period, particularly high-production cows, which need nutrients in greater quantity to meet the required demand. The aim of this study was to determine the prevalence of subclinical hypomagnesemia in pre- and post-partum dairy cows inserted in milk-production systems in the Sousa microregion and the district of São João do Rio do Peixe, both in the State of Paraíba, Brazil. As such, visits were made every two weeks to 34 rural properties, where the team collected 357 blood samples by venepuncture, 106 from pre-partum lactating cows and 251 from lactating cows in the post-partum period. It was found that the properties supplied three types of mineral supplement: a single supplement of NaCl, a supplement of NaCl + mineral base, and a commercial supplement. The cows receiving the commercial mineral supplement had the highest prevalence (10.53%) of the disorder, even showing a significant difference (P < .05) between the other types of supplement. In relation to reproductive period, it was found that the post-partum cows had a higher prevalence of subclinical hypomagnesemia (9.96%) than did the pre-partem cows (8.49%); there was, however, no significant difference (P > .05) between the two. Studies such as this are fundamental for alerting rural and technical producers to the occurrence of subclinical hypomagnesemia in the region, in addition to the damage caused by metabolic disorders.

“…As baixas concentrações plasmáticas de glicose registradas no terço final da gestação, fazem com que organismo da vaca desencadeie alterações metabólicas, como um aumento na secreção de GH (responsável por distribuir a glicose para os órgãos e suas funções) na corrente sanguínea, que irá desenvolver uma resistência insulínica (tecido adiposo, fígado e músculos), além disso, haverá também uma redução nas concentrações de IGF-1 (fator de crescimento como insulina), que desencadeará uma queda brusca na lipogênese (síntese de ácidos graxos e triglicérides), o que predispõe a lipólise do tecido adiposo (degradação de lipídios em ácidos graxos e glicerol) e a gliconeogênese hepática, com desvio da glicose para o desenvolvimento fetal e para a glândula mamária com síntese de lactose (CUPERTINO et al, 2011;GRUMMER, 1995;LEIVA, 2014).…”

A cetose, conhecida também como acetonemia, é um distúrbio metabólico que afeta principalmente vacas leiteiras de alta produção. A elevação anormal de corpos cetônicos nos tecidos e fluidos corporais do animal ocorre devido a um déficit de energia. A quantidade de alimento/nutrientes ingeridos não é suficiente para suprir a demanda corporal do mesmo, assim como a eficiência reprodutiva que está diretamente ligada à saúde, condição corporal e sua capacidade de produção. Animais de alta produção possuem um desafio muito grande de aumentar a produção a cada lactação, com isso, estão susceptíveis a mudanças metabólicas, entre elas a cetose, clínica ou subclínica. Tal enfermidade ocorre devido a uma má adaptação metabólica do animal a sua nova condição de lactante. A elevada incidência de doenças uterinas no pós-parto de vacas leiteiras é responsável por inúmeros prejuízos para a atividade, principalmente pela redução da eficiência reprodutiva das vacas acometidas por infecções. Contudo, visto que a cetose subclínica prevalece nos rebanhos leiteiros de alta produção, o objetivo desta revisão de literatura é apresentar a patogenia e os efeitos que esse distúrbio metabólico têm sobre a reprodução das vacas de aptidão leiteira no após o parto, utilizando de indicadores como taxa de prenhez, taxa de concepção, retorno a ciclicidade, intervalo entre partos e intervalo entre parto e estro.
