Estimation of genetic and phenotypic parameters for bacteriological status of the udder,somatic cell score,and milk yield in dairy sheep using a thre…
2013
Abstract The objective of this study was to estimate the genetic parameters for infection status (INF), as indicator of mastitis, SCS (i.e., log-transformed SCC), and milk yield (MY), by using a Gibbs sampling algorithm. The data comprised 17,843 test-day records of 2040 ewes. The pedigree file included 2948 animals. A bivariate variance component analysis was performed using the TM software. Fixed effects considered in the analysis were litter size, parity, flock by test-day interaction, year by season of lambing interaction, and stage of lactation; whereas the animal, and the permanent environmental effect within and across lactations were considered as random as well as the error. Flat p…
Iron deficiency risk factors in infants at one year: A cross-sectional study
1985
A cross-sectional study was performed to assess the relative importance of well-known risk factors for iron deficiency in one-year-old children and to detect new ones. Serum ferritin, erythrocyte protoporphyrin and haemoglobin were used as diagnostic tools to screen for iron deficiency. Epidemiologic analysis of data included measures of association, potential impact and a log-linear model to obtain adjusted measures. Socioeconomic variables show a strong association with iron deficiency (low income, odds ratio = 5.07, UCL = 16.08, LCL = 1.60; unemployed father, odds ratio = 4.16, UCL = 14.94, LCL = 1.16; emigration, odds ratio = 9.14, UCL = 54.56, LCL = 1.53). Some errors in feeding practi…
Effects of mountain grassland maturity stage and grazing management on carotenoids in sward and cow's milk
2006
Carotenoids are involved in the sensorial and nutritional values of dairy products. In grazing systems, both herbage maturity stage and grazing management may affect the amount of carotenoid ingested, thus these factors may affect carotenoid concentrations in milk. Two homogenous plots of mountain grassland (1.4 and 2.0 ha) were grazed during two cycles of growth by 6 dairy cows in mid lactation, in strip (SG) and rotational grazing (RG), respectively. We monitored the changes in carotenoid concentrations in sward and milk, measured by HPLC twice a week. Seven carotenoids were identified in the sward: violaxanthin, antheraxanthin, epilutein, lutein, zeaxanthin, ß-carotene and 13-cis ß-carot…
Mammary odor cues and pheromones: mammalian infant-directed communication about maternal state, mammae, and milk
2010
International audience; Neonatal mammals are exposed to an outstandingly powerful selective pressure at birth, and any mean to alleviate their localization effort and accelerate acceptance to orally grasp a nipple and ingest milk should have had advantageous consequences over evolutionary time. Thus, it is essential for females to display a biological interface structure that is sensorily conspicuous and executively easy for their newborns. Females' strategy to increase the conspicuousness of nipples could only exploit the newborns' most advanced and conserved sensory systems, touch and olfaction, and selection has accordingly shaped tactilely and olfactorily conspicuous mammary structures.…
Screening of lactic acid bacteria for reducing power using a tetrazolium salt reduction method on milk agar.
2013
WOS:000315703100020 ; www.elsevier.com/locate/jbiosc; International audience; Reducing activity is a physiological property of lactic acid bacteria (LAB) of technological importance. We developed a solid medium with tetrazolium dyes enabling weakly and strongly reducing LAB to be discriminated. It was used to quantify populations in a mixed culture (spreading method) and screen strains (spot method).
Milk and Dairy Products Intake Is Related to Cognitive Impairment at Baseline in Predimed Plus Trial
2021
Scope: To examine the association between milk and dairy products intake and the prevalence of cognitive decline among Spanish individuals at high cardiovascular risk. Methods and results: Cross-sectional analyses are performed on baseline data from 6744 adults (aged 55-75 years old). Intake of milk and dairy products is estimated using a food frequency questionnaire grouped into quartiles. The risk of developing cognitive impairment is based on the Mini-Mental State Examination (MMSE). A higher prevalence of cognitive decline was found in subjects who consumed more grams. Patients with worse MMSE score (10-24) consumed a mean of 395.14 ± 12.21 g, while patients with better MMSE score (27-3…
Impact of Donor Human Milk in the Preterm Very Low Birth Weight Gut Transcriptome Profile by Use of Exfoliated Intestinal Cells
2019
[Background] Own mother’s milk (OMM) is the optimal nutrition for preterm infants. However, pasteurized donor human milk (DHM) is a valid alternative. We explored the differences of the transcriptome in exfoliated epithelial intestinal cells (EEIC) of preterm infants receiving full feed with OMM or DHM.
Anti-obesity properties of the strain Bifidobacterium animalis subsp. lactis CECT 8145 in Zücker fatty rats
2018
We evaluated the effect of oral administration of Bifidobacterium animalis subsp. lactis CECT 8145 strain in Zücker fatty rats. The Zücker fatty rats were randomly divided into two groups (n=10 each) and administered either B. animalis subsp. lactis CECT 8145 (1010 cfu/day) suspended in skim milk, or skim milk alone (control group). Each treatment was administered in drinking bottles from week 5 until week 17 of age. A lean Zücker rat group (standard group) was included to provide normal values for the Zücker strain. This group was administered skim milk in the drinking bottle for the same experimental period as Zücker fatty rats. Body weight gain was greater in the fatty control group tha…
Blood cell transcript levels in 5-year-old children as potential markers of breastfeeding effects in those small for gestational age at birth
2019
BackgroundNutrition of the newborn during the early postnatal period seems to be of capital importance and there is clinical evidence showing the protective effect of breastfeeding compared with formula feeding on childhood obesity and its comorbidities. Infants born small for gestation age may be more sensitive to the type of feeding during lactation. Here, we aimed to analyze the impact of birth weight and the type of infant feeding on the expression levels in peripheral blood cells of selected candidate genes involved in energy homeostasis in 5-year-old children, to find out potential early biomarkers of metabolic programming effects during this period of metabolic plasticity.MethodsFort…
The diagnostic significance of IgG cow's milk protein antibodies re-evaluated
1996
The effect of different feeding regimens, notably the use of hydrolysed cow's milk formulas, on the development of allergic reactions and the development of cow's milk protein-IgG antibodies is still disputed. We prospectively compared the development of allergic manifestations and cow's milk protein-IgG antibodies in a total of 702 infants who were divided into six groups: Cow's milk protein antibodies were determined by an indirect immuno-fluorescent test. Antibody titres rose slowly in groups 1, 3 and 6. Children in group 5 showed two high peaks. There were no significant differences in the frequency and type of allergic manifestations between the groups. Introduction of cow's milk formu…
