The relationship between milk yield and somatic cell score (log-transformed somatic cell count) in dairy goats may involve complex pathways with recursive or simultaneous effects. Structural equation models were fitted to longitudinal data on milk yield and on somatic cell scores. Data consisted of 4 repeated records of milk production and of somatic cell score from left and right halves of the...

The objective of this study was to investigate the influence meteorological and other factors on quality quantity milk Spanish Churra sheep breed, based an analysis 359,808 controls from 9,904 ewes 15 farms in 8 years. Daily yield (DMY), fat, protein, lactose (%), somatic cell count (SCC) data were obtained monthly alternating controls. Mean, maximum, minimum temperatures (T) (°C), mean relati...

Milk production under grazing conditions is carried out in the intertropical region of hot climates due to its low cost. The Tropical Milking criollo breed (LT) characterized by hardiness this region, and high milk quality cheese yield. Grazing supplementation can increase production; however, it also change chemical composition. effect with commercial feed LT cows was evaluated concerning quan...

Daily milk, fat and protein yield and amount of somatic cells in cow milk are very important factors that influence milk performance traits. An association between polymorphisms in the kappa casein (CSN3) gene and milk production, composition and technical properties has been previously reported; however, this type of information is not available for the bovine β-carotene oxygenase 2 (BCO2) gen...

: world population has been continuously raised and therefore due to this fact new source of foods, particularly proteins, are in demand. in recent years, single cell protein has been considered as an accepted substitute for animal and plant proteins. in this study, single cell protein production was studied in a batch submerged culture using aspergillus niger ptcc5012. experimental design was ...

OBJECTIVE To evaluate factors affecting peripheral blood hematopoietic stem cell yield in patients undergoing large-volume leukapheresis for autologous peripheral blood stem cell collection. METHODS Data from 304 consecutive autologous peripheral blood stem cell donors mobilized with hematopoietic growth factor (usually G-CSF), associated or not with chemotherapy, at Hospital Israelita Albert...

The objective of the present study was to estimate genetic trends for lactation milk yield, persistency of milk yield, somatic cell count and interval between first and second calving in Holstein dairy cows of Iran. The dataset consisted of 210,625 test day and 25,883 first parity cows with milk yield recorded from July 2002 to September 2007 comprising 97 herds in Iran. Breeding values of anim...
