Lactate dehydrogenase (LDH) has been used extensively as a marker for cell death both in vitro and in vivo. The release of LDH into tissue culture medium accurately reflects cell viability in vitro. We have investigated the relationship between cell concentration and total LDH activity in samples of cell lysate.

Effects of Number of Lambs Suckled and Supplemental Protein Source on Lactating Ewe Performance
Journal of Animal Science, 1985Effects of number of lambs suckled and supplemental protein source on ewe performance were determined. Lactation performance of ewes nursing twin or triplet lambs was compared in Exp. 1 and 2. In Exp. 1, ewes giving birth to and nursing triplets produced 21% (P less than .05) more milk/unit metabolic body weight, were 10% more efficient in the ...

The Effect of lactation number and lactation stage on cows milking parameters
2019The aim of the research was to evaluate the influence of lactation number and lactation stage on cows milking parameters and to determine their influence on cows productivity. Cows were milked by GEA systrem „Mlone“ milking robots. We analyzed: milk yield (kg), average milk flow rates during first two minutes at 0-15, 15-30, 30-60, 60-120 s (kg/min ...

Effect of Lactation Stage and Number on Milk Albumin (BSA) and Somatic Cell Count
Zentralblatt für Veterinärmedizin Reihe A, 1981SummaryUnselected material consisting of composite milk samples from 1,029 Ayrshire cows was analyzed for somatic cell count (Fossomatic method) and serum albumin (BSA) concentration (radial immunodiffusion).The effect of lactation stage and number on the somatic cell count and milk BSA and their interrelationship was analyzed by computer programmes ...

Changes in the composition of mare's milk through the ordinal number of lactation
2022Mare's milk was traditionally used by nomadic peoples in the regions of Central Asia, where its use goes back a long way in history. In recent decades, the mare's milk has been researched as a functional food throughout Europe. The production of the mare's milk is technologically demanding. Changes in the composition of the mare's milk have been poorly

Effects of genotype and lactation number on health and reproductive problems in dairy cows
Proceedings of the British Society of Animal Science, 1997High producing dairy cows have been found to be more susceptible to disease (Jones et al., 1994; Göhn et al., 1995) raising concerns about the welfare of the modern dairy cow. Genotype and number of lactations may affect various health problems differently, and their relative importance may vary.

The aim of the present study was to study the effect of the season, period and number of lactation on mastitis incidence and milk yields in dairy cows. The climate in Bulgaria implies the presence of seasonal variations in mastitis prevalence in dairy cows, reared in free-stall barns all the year round: spring – 5.33%, summer – 4.9%, autumn – 4.2% and ...

The weight of the rat liver increased during pregnancy and lactation due solely to an increase in hepatocyte size. Insulin receptors were identified using 125I-labelled insulin and isolated hepatocytes in vitro. Scatchard analysis was interpreted in terms of high affinity (KD 4 nM) and low affinity (KD 80 nM) receptors for insulin.
