“…First, Ca concentrations obtained immediately postpartum do not represent a baseline value from which subsequent postpartum concentrations have fallen. Rather, they are already substantially lower than samples taken ≥1 day prepartum and reflect the drain of colostrogenesis [ 23 , 29 , 30 ]. Second, if samples are obtained several days postpartum, Ca concentrations return to prepartum baseline levels [ 16 , 23 , 29 ].…”

“…Milk production responses to supplemental oral Ca include an interaction whereby production numerically increased in high producing cows but numerically decreased in low producing cows [ 19 , 20 ] or no effect [ 21 ]. When the Ca is in the form of CaCl 2 or CaSO 4 (i.e., acidogenic salts), the associated acidogenic effect [ 16 , 22 , 23 ] may be additionally beneficial. All of the above studies employed reduced DCAD; responses to supplemental oral Ca were observed while feeding acidogenic salts.…”

Postpartum hypocalcemia is a problem in dairy cows. Both the Jersey vs. Holstein breed and increasing parity are known risk factors. Our objectives were: (1) to evaluate a simple approach to provide dietary acidogenic salts suitable for application on small dairies and (2) to evaluate the combined effects of degree of acidification and oral Ca supplementation along with breed and parity group on periparturient Ca status of Holstein and Jersey cows. Cows were moved weekly from the far-off dry pen at 260 days pregnant to the close-up pen, where all cows received the acidogenic diets. The diet was offered as a total mixed ration and CaCl2, and our source of acidogenic salts was top-dressed in liquid form and mixed in by hand. Thirty-six cows were blocked by parity group (parity = 2 vs. parity ≥ 3) and breed (Holstein vs. Jersey) and assigned to one of two treatments (no intervention or postpartum oral Ca bolus supplementation) in an alternating fashion, based on expected date of parturition. Urinary acidification appeared complete within 3–4 days. Increased urinary Ca excretion was >93% of maximum from 7–21 days before falling to <5% of maximum by 28 days. Serum Ca concentrations 12–24 h postpartum were lower for Jerseys vs. Holsteins and for parity ≥ 3 vs. parity = 2 cows. Serum Ca over 6–48 h postpartum decreased and increased, respectively, with oral Ca supplementation for parity = 2 and parity ≥ 3 cows. Decreased prepartum urinary Ca excretion and increased colostrum yield appear to be independent risk factors of hypocalcemia for parity ≥ 3 Jerseys.

“…De acordo com Oetzel (2013), Goff et al (2014) e Farnia et al (2018), a profilaxia da enfermidade engloba um correto manejo nutricional durante o período seco e de transição pré-parto, como a manipulação mineral na dieta, emprego de dietas aniônicas, monitoramento de Ca, Mg e K nas dietas pré-parto, suplementação de fontes de vitamina D e a suplementação de cálcio por via oral, podendo tais medidas ser empregadas de forma associada ou isolada. Além disso, a realização de ordenha no préparto, controle do escore de condição corporal das vacas e controle da ingestão de carboidratos em vacas periparturientes também são medidas adicionais louváveis na prevenção da enfermidade.…”

A hipocalcemia é uma doença metabólica relativamente comum em vacas leiteiras durante o período de transição, momento em que ocorrem profundas modificações hormonais, anatômicas e fisiológicas no organismo animal visando preparar a fêmea para o parto e posterior produção de leite. A referida pode ocorrer de duas formas: a forma subclínica, quando os valores de cálcio sérico se situam abaixo de 8,5 mg/dL e a forma clínica quando dos valores de cálcio abaixo de 5,5 mg/dL. Os prejuízos causados à bovinocultura de leite são consideráveis, sobretudo na forma subclínica de ocorrência, em que a ausência de demonstração de sintomatologia clínica dificulta o diagnóstico. A doença geralmente ocorre em torno de 24 a 48 horas após o parto, onde se há um decréscimo nos níveis séricos do cálcio circulantes, uma vez que se tem uma grande demanda para produção do colostro e para o parto. O diagnóstico clínico baseia-se no histórico e nos sinais clínicos do animal, e através da mensuração do mineral no sangue. A terapêutica clínica com soluções à base de cálcio demonstra bons resultados a campo quando do diagnóstico rápido e preciso. Entretanto, vale ressaltar que a profilaxia é a melhor opção, melhorada por um bom manejo nutricional no período seco e de transição, pelo acompanhamento do ECC, emprego de dietas aniônicas concomitantemente ao monitoramento da acidificação do pH urinário. Ademais, tem sido citada como uma alternativa para prevenção da hipocalcemia, o fornecimento de drench para vacas periparturientes como uma das alternativas de profilaxia à doença. A presente revisão objetiva elencar a etiologia, sintomatologia clínica, diagnóstico, tratamento e profilaxia da hipocalcemia em bovinos leiteiros.
