Human Milk Analysis Using Mid-Infrared Spectroscopy.
BACKGROUND The composition of human milk is known to vary with length of gestation, stage of lactation, and other factors. Human milk contains all nutrients required for infant health but requires fortification to meet the needs of low-birth-weight infants. Without a known nutrient profile of the mother's milk or donor milk fed to a baby, the composition of the fortified product is only an esti...
متن کاملPotential use of milk mid-infrared spectra to predict individual methane emission of dairy cows.
This study investigates the feasibility to predict individual methane (CH(4)) emissions from dairy cows using milk mid-infrared (MIR) spectra. To have a large variability of milk composition, two experiments were conducted on 11 lactating Holstein cows (two primiparous and nine multiparous). The first experiment aimed to induce a large variation in CH(4) emission by feeding two different diets:...

پژوهش حاضر با هدف بررسی اثر جیره حاوی کربوهیدراتهای غیرالیافی زیاد و بروز التهاب در گاوهای شیرده در دو آزمایش جداگانه انجام شد. در آزمایش اول 20 رأس گاو مبتلا به ورم پستان از دو گروه کم تولید و پرتولید (هر کدام 10 رأس) و 20 رأس گاو سالم از دو گروه کم تولید و پرتولید (هر کدام 10 رأس) انتخاب شدند. همه گاوها در دوره دوم و یا سوم شیردهی و در روزهای 80-120 پس از زایش بودند. میانگین تولید شیر در گروه...
Assessing fertility and welfare of dairy cows through novel mid-infrared milk- based biomarkers
<1 line> Although herd management and, more recently, selection have mitigated partially the deterioration of functional traits, these efforts are still hampered by the difficulties in direct recording of sufficient relevant phenotypes. Recent advances in the use of mid-infrared (MIR) spectroscopy, as the standardization of apparatuses, has led to the highly portable deployment...
متن کاملHow to use mid-infrared spectral information from milk recording system to detect the pregnancy status of dairy cows.
Ensuring that a cow is effectively pregnant after an insemination is a key element in the management of dairy farms. Currently, the most common pregnancy diagnosis methods are echography and transrectal palpation which have to be done by a veterinarian or another qualified person between 30 and 90 days after the insemination date. Those methods present a certain cost, might be risky and have a ...
