OBJECTIVE: To describe growth and clinical evolution of very low birth weight infants fed during hospital stay with milk from a human milk bank according to the caloric-protein value. METHOD: Forty very low birth weight infants were included: 10 were fed milk from their own mothers (GI), and 30 were fed human milk bank > 700 cal/L and 2 g/dL of protein. Growth curves were adjusted using nonlinear regression to the measured growth parameters. RESULTS: full enteral diet was reached in 6.3 days by GI and in 10.8 by GII; a weight of 2 kg was reached in 7.3 weeks for GI and in 7.8 for GII. In GI, 3/10 (33.3%) and in GII, 7/30 (23.3%) developed sepsis. Necrotizing enterocolitis did not occur in GI, but in 3/30 (10.0%) in GII. GI presented with urinary calcium > 4 mg/L in 1/10 (10.0%), urinary phosphorus (Pu) <1 mg/L in 10/10 (100%), and Ca/Cr >0.6 ratio in 1/10 (10.0%) of the cases; in GII, no children presented alterations of the urinary calcium or the Ca and Cr ratio, and Pu was <1 mg/L in 19/30 (63.3%). In terms of growth the 50th percentile for GI was a weight gain of 12.1 g/day (GI) vs. 15.8 g/day (GII), a length gain of 0.75 cm/week (GI) vs. 1.02 cm/week (GII), and a head circumference gain of 0.74 cm/week (GI) vs. 0.76 cm/week (GII). CONCLUSIONS: Human milk bank allowed a satisfactory growth and good clinical evolution for very low birth weight infants.

This study evaluated the use of bulk milk as a diagnostic tool for estimation of herd-level Neospora caninum exposure in Atlantic Canada; it was used to estimate the prevalence of dairy farms with a within-herd N. caninum-seroprevalence $ 15% in Prince Edward Island (PEI). The variation over time of N. caninum antibodies in bulk milk is also reported. Skimmed bulk milk and individual serum samples were analyzed for N. Caninum antibodies by using an enzyme-linked immunosorbent assay (ELISA). Bulk milk samples were collected in May 2004 (n = 235), May 2005 (n = 189), and June 2005 (n = 235). The prevalence of dairy farms with a within-herd seroprevalence $ 15% on PEI was 6.4% in May 2004. In May and June 2005, respectively, 10.1% and 10.2% of farms had a $ 15% within-herd seroprevalence. In 11 farms that were considered positive based on bulk milk samples, blood samples were collected from all adult cows in September 2005, in conjunction with a 4th bulk milk sample on the same day. The correlation coefficient between serology and bulk milk ELISA was 0.87. The results of this study demonstrate that the prevalence of N. caninum in dairy farms can be estimated by using a bulk milk ELISA.; Wendela Wapenaar, Herman W. Barkema, Ryan M. O’Handley...

A criação de ovinos para produção de leite no Brasil tem chamado a atenção nos últimos anos, principalmente após o bom desempenho de produtores da Serra Gaúcha. Este trabalho teve como objetivo obter informações sobre a produção, composição e rendimento em queijos do leite de um rebanho de ovelhas Santa Inês, avaliando o efeito de ocitocina exógena sobre a produção e composição do leite. O experimento foi conduzido no Setor de Ovinocultura da Universidade Federal de Lavras e nas instalações do Laticínios Serrabella Ltda, Lavras, Minas Gerais. Os animais foram mantidos em regime de confinamento, recebendo uma dieta com 12% de PB e 65% de NDT, de modo a atender suas exigências nutricionais. As ovelhas foram divididas em dois tratamentos: ordenha manual com injeção endovenosa de três U.I. de ocitocina e ordenha manual sem injeção de ocitocina (grupo controle). Realizou-se uma ordenha diária, sendo que até a desmama as ovelhas permaneceram com os cordeiros por um período de 14 horas a cada dia. Os cordeiros foram desmamados aos 60 dias e as ovelhas continuaram sendo ordenhadas uma vez ao dia, até o final da lactação. Foram coletadas amostras de leite para análise dos teores de gordura, sólidos totais e sólidos desengordurados. A duração média da lactação foi de 218 dias e não foi significativamente diferente entre os tratamentos (P > 0...

This research aimed to evaluate the occurrence of Staphylococcus aureus isolates in milk and in the milking environment of 10 small-scale farms (<400 L/d) located in the regions of Franca and Ribeirao Preto, state of Sao Paulo, Brazil. Two-hundred twenty samples of milk were collected from individual cows, along with 120 samples from bulk tank milk, 389 samples from milking equipment and utensils (teat cups, buckets, and sieves), and 120 samples from milkers' hands. Fifty-six Staph. aureus strains were isolated from 849 analyzed samples (6.6%): 12 (5.5%) from milk samples of individual cows, 26 (21.7%) from samples of bulk tank milk, 14 (3.6%) from samples collected from equipment and utensils, and 4 (3.3%) from samples from milkers' hands. Pulsed-field gel electrophoresis typing of the 56 Staph. aureus isolates by SmaI restriction enzyme resulted in 31 profiles (pulsotypes) arranged in 12 major clusters. Results of this study indicate a low incidence, but wide distribution of Staph. aureus strains isolated from raw milk collected from individual cows and surfaces of milkers' hands and milking equipment in the small-scale dairy farms evaluated. However, the high percentage of bulk milk samples found with Staph. aureus is of public health concern because raw...

O Brasil produz, aproximadamente, 130 litros de leite/habitante/ano, índice abaixo do recomendado pela Organização das Nações Unidas de 215 litros de leite/habitante/ano. Nos Estados Unidos, o principal motivo de rejeição do consumidor pelo leite está associado à presença de defeitos de sabor no mesmo. Por isso, o Departamento de Agricultura daquele país foi responsável por desenvolver uma linguagem sobre os descritores de defeitos de sabor. Estes defeitos de sabor são associados às suas causas: por absorção, por bactéria ou por contaminação química. Assim sendo, no controle da qualidade do leite, avaliações microbiológicos e físico-químicos devem ser empregados, juntamente com os avaliações sensoriais. Existem ferramentas e técnicas de marketing que captam as percepções do consumidor e interpretam estas informações de forma a aplicá-las na gestão da qualidade. Dentre as quais, destaca-se o Desdobramento da Função Qualidade (DFQ) por possibilitar a integração das áreas de Marketing e de Ciência de Alimentos. Este trabalho teve como objetivo compor a Matriz de DFQ para o Produto leite fluido e desdobrá-la quanto às características de Matéria-Prima e de Processo baseado na hipótese que com a inserção da avaliação sensorial de defeitos de sabor na Matriz de Produto...

Elementos metálicos, como cádmio e chumbo, uma vez absorvidos pelo organismo, não são completamente eliminados, provocando alterações metabólicas com redução do tempo de vida e da capacidade de trabalho nos indivíduos expostos. Bebês e crianças pequenas constituem a parcela da população que inspira preocupação, do ponto de vista toxicológico, por apresentarem maior absorção que os adultos, em razão de seus organismos não estarem completamente desenvolvidos. Sabe-se que a maior fonte de exposição ao cádmio e ao chumbo, para indivíduos sem exposição ocupacional e não fumantes, é a dieta. Nos primeiros anos de vida, o ser humano possui uma dieta baseada principalmente no leite materno e em alimentos como formulações lácteas, formulações a base de soja, cereais e alimentos na forma de purê. Por esse motivo, levantamentos da contaminação por cádmio ou chumbo nestes alimentos destinados ao público infantil possuem grande importância. O presente trabalho visou obter dados sobre a incidência de cádmio e chumbo em leite humano em seis cidades do Estado de São Paulo (Bauru, Campinas, Presidente Prudente, Ribeirão Preto, São Paulo e Votuporanga), em alimentos infantis como formulações lácteas, formulações a base de soja...

As a consequence of contamination by effluents from local electronics manufacturing facilities, the New Bedford Harbor and estuary in southeastern Massachusetts is among the sites in the United States that are considered the most highly contaminated by polychlorinated biphenyls (PCBs). Since 1993, measures of intrauterine PCB exposure have been obtained for a sample of New Bedford area infants. Among 122 mother-infant pairs, we identified four milk samples with total PCB levels that were significantly higher than the rest, with estimated total PCBs ranging from 1,100 to 2,400 ng/g milk fat compared with an overall mean of 320 ng/g milk fat for the 122 women. The congener profile and history of one case was consistent with past occupational PCB exposures. Otherwise, the source of PCB exposures in these cases was difficult to specify. Environmental exposures including those from fish consumption were likely, whereas residence adjacent to a PCB-contaminated site was considered an unlikely exposure source. In all four cases, the infants were full-term, healthy newborns. Because the developing nervous system is believed to be particularly susceptible to PCBs (for example, prenatal PCB exposures have been associated with prematurity, decrements in birth weight and gestation time...

The production of ewe milk is seasonal and milk yield per animal is low, even in specialized animals. This study aimed to verify the possibility of preserving bulk tank milk for seven days under cooling (5°C) and freezing (-5°C), verify the influence of cooling treatments and of the months of the year on the physical and chemical characteristics of the product. The chemical composition of milk, including the fat, protein, lactose and total solids contents, was not altered by cooling and freezing. Protein and lactose contents varied according to the months of the year. The average percentage and standard deviation of fat, protein, lactose and total solids was 8.10±1.30, 5.22±0.37, 4.43±0.23 and 19.34±1.54, respectively. The density, pH, titratable acidity, as well as alcohol and heat stability tests were significantly influenced by the treatments used (P < 0.05), but no differences were found between fresh and frozen milk. Prolonged refrigeration caused an increase in acidity and decrease in pH, with a consequent reduction in the stability of milk. These results demonstrated that freezing does not affect the chemical composition and physical characteristics of milk in nature and it could be a solution for the producer and the sheep milk industry.

The objective of this study was to calculate economic values for milk (MY), protein (PY) and fat productions (FY) and somatic cell count (SCC) which could be used to compose an economic index to rank animals involved in an international genetic evaluation program of Holstein cattle used in the commercial dairy population in Brazil. The main milk production systems (MPS) prevailing in the South and Southeast were defined based on the feeding management and production level of herds. To calculate feeding costs, energy requirements for the production of one kg of milk with the respective average protein and fat contents of each MPS were calculated. Feeding costs were obtained based on the regional prices of the diets' components. To calculate revenues, milk prices were obtained from the payment tables practiced by seven milk industries. Economic values were calculated from the marginal differences between revenues and costs, for the interest of maximizing the profit, assuming a fixed number of animals in the herd. The average economic values (R$) for MY, PY and FY were 0.51, 6.41 and 1.94, respectively. The economic impact of increasing the original SCC values in the individual records of cows in the population by 1% was -R$ 1.40 per cow...

BACKGROUND: There is a consensus among many authors that the newborn (NB) is particularly prone to infections of the gastrointestinal tract for multiple factors, such as the hypoxia and the artificial milk. These factors facilitate the abnormal bacterial colonization and promote a drawback in the destruction of the toxins of such bacterias. AIM: To identify the microorganisms in the breast milk, after its storage in the refrigerator at 4°C, as well as after heating and to relate the eventual clinical NB signs with the microbiologic laboratory results of the breast milk which was offered. METHODS: The samples collected contemplated the three phases of post-natal breast milk. In 16 cases, the colostrum type was obtained as yellowish milky secretion, up to the beginning of the second week after the birth. In 14 cases, the transition type was obtained as intermediate product of the mother's milk, between colostrum and the mature milk, between the 7th and the 15th day after the birth. In 14 cases, the mature type was obtained as a white opaque liquid, of light smell and sweet taste, from the 15th day after birth. The milk types obtained in the three presentations were subdivided according to the period of conservation and heating in the group colostrums...

1 page.-- Contributed to: 13 Seminar of the FAO-CIHEAM Sub-Network on Sheep and Goat Nutrition: Challenging strategies to promote sheep and goat sector in the current global context (León, Spain, oct 14-16, 2009).; Feeding a source of long chain polyunsaturated fatty acids (PUFA), such as marine lipids, plus a linoleic-rich vegetable oil notably increases milk content of some potentially healthy fatty acids (FA), such as conjugated linoleic acid (CLA). In dairy cows, this nutritional strategy causes detrimental effects on animal performance, reducing milk fat content, but the situation in sheep might be substantially different, as this species seems to be less prone to milk fat depression than cows. This work was conducted to investigate the effect of supplementation with sunflower oil (SO) plus incremental levels of marine algae (MA) on dairy sheep performance and milk FA profile. Fifty Assaf ewes in mid-lactation, distributed in 10 lots of 5 animals each, were allocated to 5 treatments (feeding regimes; 2 lots/treatment). All animals received a total mixed ration (50:50 forage:concentrate ratio) without lipid supplementation (Control) or supplemented with 25 g SO/kg DM plus 0, 8, 16, or 24 g MA/kg (SO, SOMA1, SOMA2, and SOMA3...

The growth and activity of two Lactococcus strains and one Leuconostoc strain in CO2-acidified and non-acidified refrigerated milk were evaluated separately and as a mixed culture to determine their suitability for use as a starter in the manufacture of Afuega’l Pitu, an acid-coagulated Spanish cheese, from refrigerated CO2-acidified milk. The growth of the strains studied and their production of organic acids were similar in CO2-acidified and non-acidified refrigerated or fresh milk, indicating that CO2 treatment does not affect the metabolic activity of the strains. However, refrigeration enhanced the production of acetaldehyde, ethanol and diacetyl in CO2-acidified and non-acidified milk. The level of diacetyl was also greater in refrigerated CO2-acidified milk than in refrigerated non-acidified milk. It was concluded that refrigerated milk acidified with CO2 can be satisfactorily used in the manufacture of Afuega’l Pitu cheese, and that this technique can be also used in the production of other acid-coagulated cheeses.; This work was financially supported by the Comisión Interministerial de Ciencia y Tecnología of Spain (Grant ALI96-0406).

Samples of raw materials (powdered milk, sugar, starch, oatmeal, water and milk type c –a a low credit milk) commonly used in baby bottles as well as samples of milk bollles already prepared were collected from a milk nursery in the city of São José do Rio Preto – SP (Brazil), and submitted to the microbiological analysis. The results showed a significant contamination. It was ascertained the presence of Salmonella sp in 70% of the milk bottles analysed immediately after preparation (time = 0 hour) and in 90% of samples analysed after a 24 hour storage enough to classificate the milk bottles as “products potentially causing fooborne intoxication”, and therefore, “improper for consumption”. The hiht level of contamination is more likely to be related with some of the raw materials used, enviromment or even wrong handling.; Amostras de matérias-primas (leite em pó, açúcar, amido, aveia, água e leite C) comumente utilizadas na elaboração de mamadeiras, assim como amostras de mamadeiras já preparadas, obtidas de um lactário de São José do Rio Preto – SP, foram submetidas à análises microbiológicas.

The content of insulin-like growth factor 1 (IGF-1) in bovine milk in México is unknown, and high levels could increase the health risk for adult people who ingest milk. The aim of this study was to determine the level of IGF-1 and its relationship with fat content using liquid chromatography with ion trap as a mass detector in milk marketed in Durango, México. During 18 months we analyzed, three times, six lots chosen randomly of whole, reduced-fat, and low-fat milk of three brands. Each sample was pre-treated using cut-off membranes, digested with trypsin, and subjected to liquid chromatography-mass spectrometry. There was a significant difference in the mean concentration of IGF-1 between the brands and types of milk analyzed (Chi square=34.66; p≤0.005). The correlation analysis revealed a positive exponential association between IGF-1 concentration and the fat content of milk with determination coefficients of 0.950 for brand 1, 0.974 for brand 2, and 0.984 for recombinant bovine growth hormone-free. To the best of our knowledge, this is the first study documenting an association between IGF-1 levels and fat content in milk. The decision to consume a brand with or without fat depends on the milk taste and IGF-1 requirements.

OBJECTIVE: To understand the relative contributions of breast milk and the weaning diet to overall nutrient intake, with a view to designing and implementing appropriate programmes to improve complementary feeding in developing countries. METHODS: Complementary food intake was measured in a sample of 250 toddlers (mean baseline age: 13.9 ± 2.4 months) using 24-h dietary recall interviews administered once every 3 weeks over a 6-month period. Breast-milk intake over a 24-h period was measured using the test-weighing method in a subsample of 50 children. Regression effects of age and sex on observed milk intakes were estimated and imputed to the whole sample to estimate mean intake over the observation period. Total energy and nutrient intakes were evaluated for adequacy with reference to published estimates of toddler requirements. FINDINGS: Total energy intake (1029 kcal/day) was adequate, with breast milk supplying an average of 328 kcal/day (32%), but vitamin A, riboflavin, calcium, iron and zinc intakes were below current estimates of required intakes. Observed limitations in nutrient intake were consistent with the finding that almost half of the toddlers were stunted. The prevalence of wasting was 6% at baseline and 4% at final assessment. Although food consumption increased when breastfeeding stopped...
