Feeding habits and trophic level of Himantura gerrardi (Elasmobranchii; Dasyatidae) in northern Oman Sea: effects of sex and size class
The feeding habits and trophic level of Himantura gerrardi were studied according to sex and size classes of 80 individuals obtained using bottom trawl between May and December 2014 from the Oman Sea. Collected specimens were divided into three size classes (small<38 cm, medium 38-58 cm and large>58 cm) based on disk width. Prey was identified in seven main zoological categories, where crustace...
متن کاملFeeding to Minimize Nutrient Requirements for Maintenance and Increase Milk Production
Feed costs represent greater than 50% of the costs of producing milk. Several practical strategies have been applied to help minimize costs, including reduced feed losses during storage, reduced shrink at feed out, and determining favorable pricing for commodity feeds. Much less attention has been directed towards improving feed efficiency in dairy cattle. Although recognized as an important co...
متن کاملEffect of Natural-Feeding Education on Successful Exclusive Breast-Feeding and Breast-Feeding Self-Efficacy of Low-Birth-Weight Infants
OBJECTIVE The ideal nourishment for newborns with low birth-weight is breast milk. The purpose of the study was to determine the effect of natural-feeding education given to mothers of low-birth-weight infants, on the mothers' breast-feeding self-efficacy level, breast-feeding success, and the growth of the infants. METHODS The study was conducted in a quasi-experimental way. The study group ...
متن کاملCruciferous vegetable feeding alters UGT1A1 activity: diet- and genotype-dependent changes in serum bilirubin in a controlled feeding trial.
Chemoprevention by isothiocyanates from cruciferous vegetables occurs partly through up-regulation of phase II conjugating enzymes, such as UDP-glucuronosyltransferases (UGT). UGT1A1 glucuronidates bilirubin, estrogens, and several dietary carcinogens. The UGT1A1*28 polymorphism reduces transcription compared with the wild-type, resulting in decreased enzyme activity. Isothiocyanates are metabo...
متن کاملAssociation of breast-feeding and feeding on demand with child weight status up to 4 years.
OBJECTIVES The mechanisms underlying the protective effect of breast-feeding on the development of childhood overweight are unclear. This study examines the association of breast-feeding with weight gain in the first year, and body mass index (BMI) and overweight up to 4 years. In addition, we examine possible mechanisms of this effect (i.e., feeding pattern, eating style, unhealthy snacking be...
