Resumo: The effects of pre-delivery administration of bovine somatotropin (bST) on first lactation performance were evaluated in this study, which involved eighteen Holstein pregnant heifers. Nine animals were supplemented with subcutaneous injections of 500 mg of bST, on days 21 and 9 prior expected delivery, and 9 were not supplemented (control group). Animals were fed total mixed ration, twice daily. Data evaluated in this experiment were related to sanitary, reproductive and productive parameters during first lactation. Administration of bST did not affect parameters related to sanity (retained placenta, metritis, displacement abomasum, milk fever, ketosis), reproduction (follicular cysts). However, heifers supplemented with bST showed changes of body condition score 65% greater, anticipated milk production peak in 9.7 days and decreased number of days in lactation in 21,8 days, compared to the non-supplemented ones (p < 0.05). Milk production peak and milk production corrected for 305 days were not affected by bST administration.

Os animais foram alimentados com dieta total, 2 vezes ao dia, e os dados coletados foram relativos a parâmetros sanitários, produtivos e reprodutivos na primeira lactação. A administração de bST não afetou os parâmetros sanitários (retenção de placenta, metrite, deslocamento de abomaso, febre do leite e cetose) e reprodutivo (cisto folicular). Entretanto, o uso de bST no pré-parto levou à variação de escore de condição corporal (ECC) 65% maior, adiantou o pico de produção de leite em 9,7 dias e diminuiu os dias em lactação em 21,8 dias em relação ao controle (P < 0,05). O pico de produção de leite e a produção de leite corrigida para 305 dias não foram afetados pela administração de bST.Editora da Universidade Estadual de Maringá2008-04-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/252410.4025/actascianimsci.v24i0.2524Acta Scientiarum.
