OBJECTIVE The objective of the study was to evaluate whether lactation duration is associated with lower prevalence of metabolic syndrome (MetSyn) in midlife, parous women. STUDY DESIGN This was a cross-sectional cohort analysis of 2516 parous, midlife women using multivariable logistic regression to determine the independent association of lactation and lactation duration on prevalence of Me...

The aim of the present research was to determine hematological and biochemical parameters Travnik pramenka ewes during lactation. Thirty‐six in average age 3-5 years were included research. They monitored three stages lactation: early, medium, late stage. WBC RBC, HGB concentration, HCT MCH values increased significantly as lactation progressed, while significant decrease MCV MCHC determined bl...

Long-chain fatty acids mobilized during early lactation of dairy cows are increasingly used as energy substrate at the expense of acetate. As the synthesis of acetate in the rumen is closely linked to methane (CH4) production, we hypothesized that decreased acetate utilization would result in lower ruminal acetate levels and thus CH4 production. Twenty heifers were sampled for blood, rumen flui...

Lactating, primiparous Landrace x Yorkshire sows were used to characterize LH secretion during lactation in sows that experienced an early (less than 9 d; n = 14) or late (greater than 15 d; n = 9) return to estrous postweaning and to evaluate the relationship between LH secretion and blood metabolites. Twenty-three sows were fed one of nine corn-soybean meal diets to achieve a matrix of lysine...

Staphylococcus aureus is among the main etiologic agents of bovine mastitis. A total of 83 isolates of S. aureus from mammary glands of primiparous heifers were collected in the prepartum, calving and during lactation. For lactating cows, a total of 27 isolates of S. aureus from mammary glands were collected during lactation. The samples were taken in two dairy farms located in Sao Paulo State...

Captive wapiti hinds were observed during seven periods between June 1996 and November 1997. We investigated their activity and foraging behaviour on two pastures, heavily and lightly grazed, during four phases of the reproductive cycle (early gestation, late gestation, peak lactation, and late lactation). Within season, differences in forage availability between pastures had little apparent ef...

The present study was conducted to evaluate the effects of using raw or microwave irradiated safflower seed on dry matter intake, milk production and composition, milk fatty acid profile, blood parameters, and nutrient apparent digestibility in early lactation cows. Nine multiparous Holstein cows at early lactation were randomly assigned to one of three treatments based on 3 × 3 balanced latin ...

Dairy cattle experience a remarkable shift in metabolism after calving, after which milk production typically increases so rapidly that feed intake alone cannot meet energy requirements (Bauman and Currie, 1980; Baird, 1982). Cows with a poor adaptive response to negative energy balance may develop hyperketonemia (ketosis) in early lactation. Cows that develop ketosis in early lactation lose mi...

Each stage (early, middle and late) of lactation is a critical period during which maternalmalnutritional can negatively effects on the offspring's body development. We investigatedthe maternal high fat diet (HF) different stages bodyweight male offspring at weaning. Female Wistar rats were fed either HF only duringthe first week (HF1-7 group), second (HF7-14 third (HF14-21 group) andth...
