Luteinizing hormone pulsatile release and the length of lactational amenorrhoea.

Human reproduction (Oxford, England), 1996
The pattern of luteinizing hormone (LH) pulsatile release and the mean concentrations of follicle-stimulating hormone, oestradiol and progesterone were studied in nursing and non-nursing women. Blood samples were drawn at 5 min intervals between 10:00 and 14:00 h and between 22:00 and 02:00 h at months 3-4, 5-6, 7-8 and 9-10 postpartum in nursing women

Endocrinology: Luteinizing hormone pulsatile release and the length of lactational amenorrhoea

Human Reproduction, 1995
The pattern of luteinizing hormone (LH) pulsatile release and the mean concentrations of follicle-stimulating hormone, oestradiol and progesterone were studied in nursing and non-nursing women. Blood samples were drawn at 5 min intervals between 10 :00 and 14 :00 h and between 22 :00 and 02 :00 h at months 3-4, 5-6, 7-8 and 9-10 post-partum in nursing ...

Stage length, spline function and lactate minimum swimming speed.

The Journal of sports medicine and physical fitness, 2004
Lactate minimum test (LMT) has become popular in running evaluation. This study analysed the influence of different stage lengths and determination methods on lactate minimum swimming speed (LMS) and its validity for maximal lactate steady-state speed (MLSS-S) assessment.Twelve male swimmers (19.7+/-1.6 years, 70.3+/-8.7 kg, 181.4+/-7.9 cm) randomly ...

The effect of the foaling season on lactation length and milk production of jennets

2011
The effects of the foaling season and the lactation phase on the milk productive variables were investigated on 34 pluriparous jennets fed with hay, concentrate and pasture. From the 21st post-foaling day, the jennets were manually milked without the foal, one time a day, after 5 hours from the foal' separation.

Effect of length of lactation on the annual milk yield of cows

The study main objective was to explore how lactation length and service period affect milk yield in dairy cows. It explained that measuring the duration a cow produces milk (lactation length) and the gap before a new pregnancy period after calving (service period) helps determine overall productivity of the cow.
