O presente trabalho procurou verificar o comportamento de bovinos zebus, em crescimento e em regime de pasto, face a não administração do sal comun (NaCl comercial). Foi na Fazenda Experimental de Criação, localizado no município de Sertaozinho, São Paulo. O delineamento experimental foi o de blocos casualizados em número de 4, com 2 tratamentos e duas repetições dentro dos blocos, perfazendo 8 repeticoes por tratamento. O lote A, que recebeu NaCl a vontade, ganhou no fim de 851 dias de experimento, 2.226kg e o lote B, sem NaCl, 2.245kg. A análise estastística revelou que não houve efeito significativo entre os tratamentos e blocos ao nível de 5% de probabilidade. Mas houve efeito significativo a 1% de probabilidade entre raças. Admitiu-se como provável que os animais teriam recebido quantidade de NaCl suficiente através da ingestão de capim, água e terra, pois a falta do sal não alterou o crescimento de bovinos zebus, durante o período de 2 anos, quando, em pastoreio, nas terras roxas de Sertaozinho. |

Inbreeding has been associated with the impairment of reproductive performance in many cattle breeds. Although the usage of reproductive biotechnologies has been increasing in bovine populations, not much attention has been given to the impact of inbreeding over cow?s performance on artificial reproduction. The objective of this study was to estimate the impact of inbreeding on in vitro embryo production in a Guzerá breed population. The inbreeding coefficient (F), calculated as half of the co-ancestry of the individual?s parents, was used as an estimate of inbreeding. The inbreeding coefficients of the donor, sire (used on in vitro fertilization) and of the embryos were included, separately, in the proposed models either as classificatory or continuous variables (linear and quadratic effects). The percentage of non-inbred individuals (or embryos) and mean F of donors, embryos and sires were 29.38%; 35.76%; 42.86% and 1.98±2.68; 1.32±3.13; 2.08±2.79, respectively. Two different models were considered, one for oocyte production traits and other for embryo production traits. The increase of F of the donor significantly (P<0.05) impaired the number of viable oocytes (N OV), number of grade I oocytes (N GI) and number of cleaved embryos (N CLV). Moreover, the donor?s F influenced the percentage of grade I oocytes (P GI), percentage of viable embryos (P EMB) and percentage of cleaved embryos that turned into embryos (P CXE). No significant (P>0.05) effects were observed for the sire (father of the embryos) inbreeding coefficient over the traits analysed. Embryo?s F influenced (P<0.05) the number of viable embryos (N EMB), percentage of viable embryos (P EMB) and percentage of cleaved embryos that turn into embryos (P CXE). Results suggested that an increase in the inbreeding coefficient might impair the embryos ability to survive through challenges imposed by the in vitro environment. Submitting highly inbred Guzerá female donors to in vitro embryo production may, in the long-term, have negative implications on the number of embryos obtained per cow and increase the relative costs of the improvement programmes based on this technology. High levels of inbreeding should be avoided when selecting Guzerá female donors and planning in vitro fertilization mating.
