Body condition score (BCS) is a useful tool in assessing the energy status of dairy cattle. Previous research has shown that it is heritable and genetically correlated to reproductive performance. Currently, interest exists in developing selection indexes for fertility that include BCS information. Before such indexes are developed, it is important to assess the genetic covariance between BCS a...

Maternal adipose tissue is a major contributor to breast milk long-chain fatty acids, probably through the pool of plasma NEFA. The fatty acid composition of the erythrocyte membrane (EM) is a biochemical index of the intake of fatty acids not synthesized endogenously and of PUFA and long-chain PUFA fatty acid status. The present study investigated the associations between breast milk fatty aci...

BACKGROUND The Nutrient Rich Foods (NRF) Index is a formal scoring system that ranks foods on the basis of their nutrient content. When used in conjunction with a food prices database, it can help identify foods that are both nutritious and affordable. OBJECTIVE Our aim was to identify healthy, affordable foods and food groups by using the NRF index and US Department of Agriculture (USDA) nut...

This study analyzes the linear relationship between climate variables and milk components in Iran by applying bootstrapping to include and assess the uncertainty. The climate parameters, Temperature Humidity Index (THI) and Equivalent Temperature Index (ETI) are computed from the NASA-Modern Era Retrospective-Analysis for Research and Applications (NASA-MERRA) reanalysis (2002-2010). Milk data ...

BACKGROUND Sweet drinks early in life could predispose to lifelong consumption, and the beverage industry does not clearly define fruit drinks as part of the sweet drink category. OBJECTIVES To ascertain the relationship between beverage selection and dietary quality of the lunches packed for preschool-aged children evaluated using the Healthy Eating Index-2010. METHODS Foods packed by pare...

Background: The Nutrient Rich Foods (NRF) Index is a formal scoring system that ranks foods on the basis of their nutrient content. When used in conjunction with a food prices database, it can help identify foods that are both nutritious and affordable. Objective: Our aim was to identify healthy, affordable foods and food groups by using the NRF index and US Department of Agriculture (USDA) nut...

AIMS The excretion of low molecular weight heparin (LMWH) in breast milk was investigated in 15 lactating mothers after Caesarean section. METHODS Blood and milk samples were collected before and 3-4 h after once daily routine subcutaneous injection of 2500 IU dalteparin. Anti-Xa activity was measured by an assay utilizing prolonged clotting times in plasma or breast milk as an index of LMWH ...

Performance, carcass and meat quality were assessed in 3 groups of Brown Swiss male calves, all of them suckled by their dams: groups M200 and M250 were exclusively milk-fed and slaughtered at 200 or 250 kg, respectively, and G400 group was supplemented with grain and slaughtered at 400 kg after a short finishing period. Increasing weight in milk-fed animals led to an increase in dressing perce...

We first sought to clarify the effects of discounted rate, survival rate, and lactation persistency as a component trait of the selection index on net merit, defined as the first five lactation milks and herd life (HL) weighted by 1 and 0.389 (currently used in Japan), respectively, in units of genetic standard deviation. Survival rate increased the relative economic importance of later lactati...

this study was carried out to investigate the possibility of prediction the occurrence of heat stress in dairy cows and determination of climate critical periods. the most common indexes for estimation the degree of thermal stress istemperature humidity index (thi). in this study yousef’s thi index (1985)was used to analyze the yearly and monthly effects of temperature and humidity. meteorologi...
