Gestão da qualidade total: introdução dos conceitos e a sua utilização em um curso para abordar o comportamento individual do aluno/profissional/cidadão

A introdução do assunto qualidade, segundo as necessidades de mercado abre espaço para a discussão da qualidade como necessidade pessoal, e também para a formação do cidadão/profissional, além de introduzir assuntos específicos de administração de empresas. Dessa forma, foi oferecida uma disciplina optativa para os alunos do Instituto de Química do Campus de Araraquara, abordando o tema Qualidade e foi denominada Gestão da Qualidade por três anos seguidos. da avaliação geral do curso extraiu-se que ele deveria ser realizado sempre, que o tema é atual e relevante e contribui para a formação profissional/pessoal. Com relação ao comprometimento com o curso de graduação, cerca de metade dos alunos assume o seu comprometimento com os estudos e os restantes dizem estarem somente envolvidos. Conclui-se, portanto que o curso atingiu os seus objetivos propostos, introduziu os principais conceitos de qualidade segundo as normas da qualidade da série ISO 9000 e suscitou a discussão da formação do aluno/profissional/cidadão.

Reduction in incidence of experimental fowl typhoid by incorporation of a commercial formic acid preparation (Bio-Add™) into poultry feed

The experiment described evaluated the effect of a commercial in-feed preparation (Bio-Add™) involving a mixture of formic acid and propionic acid on the incidence of experimental fowl typhoid in groups of 41 and 42 1-wk-old Rhode Island Red chickens. The chickens were infected through contact with 12 identical chickens that had been inoculated orally with 10 8 cfu of Salmonella gallinarum strain 9. The incidence of mortality and morbidity due to fowl typhoid was 31/41 (76%) in birds given untreated feed and 14/42 (33%) in birds given feed treated with Bio-Add™.

Evaluation of the hypothalamus-pituitary axis response to exogenous GnRH, estradiol benzoate, And LH during the postpartum period in Nellore cows

The objective was to evaluate when the LH reserve was re-established in postpartum Nellore (Bos indicus) cows by evaluating the response of the hypothalamic-pituitary axis responsiveness to exogenous GnRH or estradiol benzoate (EB). Additionally, we tested the influence of dietary supplementation (SUPL) and calf removal (CR) on the duration of postpartum anestrus. Ninety multiparous lactating Nellore cows were randomly assigned to eight groups. The EB and GnRH groups received 1.0 mg EB (N = 7), and 50 μg lecireline (N = 16), respectively. Additional cows were given the same hormones, and subjected to either nutritional supplementation (EB-SUPL, N = 9; GnRH-SUPL, N = 16), or calf removal at 72 hours after calving (EB-CR, N = 4; GnRH-CR, N = 13). The remaining two groups were the LH (12.5 mg, N = 14) and control groups (saline, N = 11). Hormones were administered weekly from 7 (±5) days postpartum to first ovulation (detection of a CL during a weekly ultrasonographic examination). Blood samples were collected just before and 2 hours (GnRH, LH, and control groups) or 18 hours (EB groups) after hormone or saline (control) administration. Ovulation occurred as early as 15 days postpartum in the GnRH group. The mean ± SEM intervals (days) from calving to first ovulation were EB, 87.7 ± 4.2; EB-CR, 20.3 ± 1.2; EB-SUPL, 60.3 ± 3.2; GnRH, 40.4 ± 2.1; GnRH-CR, 21.0 ± 1.1; GnRH-SUPL, 26.4 ± 1.1; LH, 35.6 ± 1.1; and control, 60.9 ± 2.1. We concluded that there was sufficient LH in the pituitary gland (of Nellore cows) from the second week postpartum to induce ovulation in response to exogenous GnRH. Additionally, calf removal and nutritional supplementation reduced, by 2 to 4 weeks, the interval from calving to an LH increase and ovulation induced by GnRH or EB. © 2013.
