Abstract: the acquired immunity by newborns calves is dependent of ingestion and absorption of adequate quantity of colostral immunoglobulins. supplemental pooled colostrum can be an important procedure to correct miscarried management. this study was performed to evaluate the effect of additional colostrum of super immunological quality at 12 hours of live on total serum protein and immunoglobulin g concentration in newborn calves. fourty five newborn calves, separated in two treatments: treatment 1 - additional colostrum 12 hours after birth (10% body weight) and treatment 2 - control, were evaluated. according to the initial level of passive immunity, the animals were allocated to the groups described as follows: group 1 (low level supplemented) igg<20 mg/ml); group 2 (high level suplemented) igg> 20 mg/ml; group 3 (low level control) igg<20 mg/ml); and group 4 (high level control) igg> 20 mg/ml. the average concentration of pooled colostrum was 68,49 ± 4,21 mg/ml. in the animals with adequate levels of antibodies, despite of the additional colostrum, the concentrations were similar at all ages, without significant differences. however, in the group with low level of passive immunity the additional colostrum promoted a compensation effect with animals reaching the levels comparable with the ones with normal initial concentration of serum antibodies

Abstract: the objective of this study was to evaluate the effect of storage temperature and sample age on the total bacterial count (tbc) of milk samples preserved with azidiol to verify whether a single sample could be used to perform regulatory milk analysis under the normative instruction 51 (in-51). three hundred and twenty milk aliquots were used collected from an expansion tank to assess three storage temperatures (0 oc - frozen: 7 oc - refrigerated, and 24 oc - room temperature), three types of conservation (bronopol, azidiol and no preservative) and four sample ages (1, 3, 5, and 7 days). for the total bacteria count, refrigerated control samples, with azidiol and one day old samples, and for composition and somatic cell count (scc), the controls were defined as one day old refrigerated samples containing bronopol. samples conserved with bronopol presented lower total bacteria count than the control regardless of storage temperature and sample age. milk samples conserved with azidiol and stored refrigerated presented lower scc, regardless of age, compared to refrigerated samples conserved with bronopol. the fat and lactose contents decreased after the fifth day. two samples had to be collected: one for scc determination and composition containing bronopol and another for the total bacteria count containing azidiol. milk samples used for total bacteria count can be tested up to 7 days if they are kept at 7 oc with the addition of azidiol.

Abstract: the mda (master dairy administration) system was created as a result of management practices developed by and effectively utilized in the industrial sector since the early 1990's. it was designed by applying the five basic management principles to reach success in business. these principles, along with survival principles in the activity, delineated the features of the mda system. it can be characterized as a strategic system which targets the ends from start, that is, the definition, a prior, of targets and deadlines is a primary condition to carry out any task. therefore, there is a need to measure and follow up procedures. if results are not reached, questions must be placed on the training offered to employees or on the methods utilized, but never on the people. moreover, all people interested in the business must have their expectations met - shareholders, customers, employees and the society.

Abstract: The aim of this study was to use the statistical process control (SPC) as a tool of recognition and rating for farms with larger probabilities of infraction of milk quality standards used by industry. Data of somatic cell count (SCC) and total bacterial count (TBC) from 452 farms were used. Proportion of infractions of quality standard was calculated considering limits of SCC = 400,000 cells/mL and TBC = 100,000 CFU/mL. Indices Cpk were calculated and farms were rated according to four categories of Cpk means and indices. The farms which presented larger means and standard deviation had larger frequencies of violation. Farms with means lower than limits proposed to SCC and TBC represented, respectively, 25.05 % and 97.78 % of farms. However, proportion of farms that provided milk consistently within the quality standards evaluated (Cpk ≥ 1) represented 4.65 % and 35.17 % of farms for SCC and TBC, respectively. Therefore, the Cpk index can be used by the industry associated with the current models to characterize milk quality from farms, since it identifies more consistent herds in producing quality-standard milk.

Abstract: data comprising 39,578 test-day records of 3,766 first lactation holstein cows calving from 1994 to 2002 was used to estimate genetic parameters for test-day yields (tdy) and 305-day milk yield (my305) and to compare two selection criteria. variance components were estimated by restricted maximum likelihood using univariate and bivariate animal models. the tdy models included the additive genetic random effect and the fixed effects of contemporary groups and the regressions of calving age (linear and quadratic effects) and days in milk (linear effect). the model used to analyse my305 included lactation length in place of days in milk effect. contemporary groups were defined by herd, and year and month of test for tdy, and by herd and calving season for my305. heritability estimates for my305 from one-trait and two-trait analyses were 0.27 and 0.25, respectively. heritabilities for tdy estimated by univariate and bivariate (my305 and tdy) analyses ranged from 0.11 to 0.31 and from 0.08 to 0.25, respectively. highest heritability estimates were obtained for 4th and 5th tdy, corresponding to the 2nd and 3rd months of lactation. genetic correlations between my305 and tdy were positive and high, ranging between 0.83 and 1.00. the results suggest that traditional direct selection for my305 would result in larger genetic gains in most of tdy across lactation. direct selection for tdy would result in genetic gains for my305, but they would be smaller than those achieved by direct selection.

Abstract: O objetivo deste trabalho foi validar modelos de predi o de nitrogênio uréico no leite (NUL), visando contribuir para avalia o nutricional de dietas de vacas. Foram utilizadas 8.833 observa es de vacas holandesas de um rebanho comercial. A produ o de leite, o pesovivo, o número de dias em lacta o e o número de lacta es foram coletados no dia da amostragem do leite. Amostras de leite foram coletadas mensalmente para determina o da sua composi o. Para a avalia o dos 3 modelos, foram medidas acurácia, precis o e robustez. O modelo 3, apesar de mais acurado (viés=-0,21 mg/dL), foi menos preciso (erro residual=5,24 mg/dL) que o modelo 2 (viés=-1,72 e erro residual=4,90 mg/dL), enquanto o modelo 1 foi o menos acurado (viés=2,93 mg/dL) e o menos preciso (erro residual=5,99 mg/dL). Houve falta de robustez para os 3 modelos. Os três modelos de predi o de NUL diferiram entre si quanto à acurácia, precis o e robustez. The objective of this study was to validate prediction models for milk urea nitrogen (MUN), aiming at evaluating utilization efficiency of diets for dairy cows. Data (8,833 observations) from Holstein cows were used. Milk production, body weight, days in milk and lactation number were collected on the milk sampling days. Milk samples were collected monthly for composition analysis. In order to evaluate the three models, accuracy, precision and robustness were tested. Despite being more accurate (mean bias=-0.21 mg/dL), model 3 was less precise (residual error=5.24 mg/dL) than model 2 (mean bias=-1.72 and residual error=4.90 mg/dL), while model 1 was the least accurate (mean bias=2.93 mg/dL) and the least precise (residual error=5.99 mg/dL). There was lack of robustness for the three models. Models for predicting MUN differ among themselves with regard to accuracy, precision and robustness.

Abstract: This correlational study investigated the effects of the peripartum health disorders and your respective risk factors about the milk production, in the peak and to the 305 days in lactation. Holsteins cows (n = 522) of a commercial herd of the State of S o Paulo, had your health and nutritional status accompanied since the beginning of the period pre-calving to the end of the lactation. Occurrence of diseases, score of body condition (at the dry off and calving), daily milk productions and milk compositions, were recorded. For statistical analysis of the data, the logistics regression and the analysis of multiple regression were used. The obtained results demonstrated that the diseases of the peripartum and your risk factors affected the milk production with different effects in function of the lactation numbers, demanding this way, larger care with the prophylactic measures to avoid the diseases, and to maximize the production of milk and the reproduction of the animals. Este estudo correlacional investigou os efeitos das ocorrências sanitárias do periparto e seus respectivos fatores de risco sobre a produ o de leite, no pico e aos 305 dias em lacta o. Vacas Holandesas (n = 522) de um rebanho comercial do Estado de S o Paulo tiveram seu desempenho sanitário e nutricional acompanhados desde o início do período pré-parto até o final da lacta o. A ocorrência de doen as, os escores de condi o corporal (no pré-parto e parto), as produ es de leite e as composi es do leite foram registradas. Para análise estatística dos dados, foram utilizadas a regress o logística e a análise de regress o múltipla. Os resultados obtidos demonstraram que as doen as do periparto e seus fatores de risco afetaram a produ o de leite com efeitos diferentes em fun o do número de lacta es, exigindo desta maneira maior cuidado com ado o de medidas profiláticas para se evitar as doen as e maximizar a produ o de leite dos animais.
