OBJECTIVE There is conflicting evidence as to whether duration of lactation may decrease the risk of subsequent development of an unfavorable maternal metabolic profile, including overweight and obesity. We hypothesized that duration of lactation is associated with a more favorable metabolic profile and healthier anthropometric measurements. SUBJECTS AND METHODS Ninety-eight parous women were...

Knowledge related to udder health in dairy practice is considerably limited. The aim of the experiment was to study the changes of somatic cell counts (SCC) in milk in relation to the month of year, stage of lactation and parity under the practical conditions. Also the frequency of incidence of high SCC during the year was observed. The effectiveness of dry therapy and calving process on SCC wa...

in this study a total of 171,360 monthly test day milk records obtained from first lactation of iranian holstein cattle (three times a day milking) distributed in 96 herds and calved from 1999 to 2008 were used to estimate genetic parameters and to predict breeding values of the animals. the data was analyzed using random regression test day model. the results showed that average of heritabilit...

to have an, idea about the relation between the length of birth interval and lactation, and birth control program this study have been done. the material for such analysis was nomad women's fertility history that was in their reproductive period (15-44). the material itself was gathered through a health survey. the main sample was composed of 2,165 qualified women, of whom 49 due to previous or...

UĞURLU, M., I. KAYA and M. SARAY, 2016. Effects of some environmental factors on calf birth weight and milk yield of Anatolian Water Buffalo (Bubalus bubalis). Bulg. J. Agric. Sci., 22: 995–998 This research was conducted to determine the effects of some environmental factors on calf birth weight, milk yield and lactation length in Anatolian Water Buffalo. The data on birth weight of 1006 buffa...

Data on 657 lactation from 163 Maltese goat, collected over a 5-year period were analyzed by a mixed model to estimate the variance components for heritability. The considered lactation traits were: milk yield (MY) and lactation length (LL). Year, parity and type of birth (single or twin) were significant sources of variation for lactation length; on the other hand milk yield was significantly ...

The study aimed to determine factors affecting the dry period length and effect of dry days on milk yield, milk composition and lactation length in the next lactation of dairy cows. Data used for analysis included 7264 lactation records collected from 2012 to 2016 on 4737 Holstein cows raised in 152 herds. The statistical model used to determine the factors influencing the dry period length sho...

OBJECTIVES Intact postural control is essential for safe performance of mountain sports, operation of machinery at altitude, and for piloting airplanes. We tested whether exposure to hypobaric hypoxia at moderate altitude impairs the static postural control of healthy subjects. METHODS In 51 healthy men, median age 24 y (quartiles 20;28), static control was evaluated on a balance platform in ...
