The milk somatic cell count (MSCC) forms the basis of abnormal milk control programs world wide for goats, cows and sheep. To better understand factors that contribute to elevations in MSCC, the effects of stage of lactation, parity, breed and state/area in the United States (US) on MSCC were examined. Least squares means were calculated on composite milk somatic cell scores from 26,607 goats, ...

Epidemiological findings suggest that the consequences of a given oncogenic stimulus vary depending upon the developmental state of the target tissue at the time of exposure. This is particularly evident in the mammary gland, where both age at exposure to a carcinogenic stimulus and the timing of a first full-term pregnancy can markedly alter the risk of developing breast cancer. Analogous to t...

The objective of the current study was to evaluate the effect of bovine somatotropin (bST) on milk yield and composition of Holstein cows in early and very early lactations. Twenty-two lactating Holstein cows averaging 62 days in milk (DIM:25-115), 28.5 kg/d milk, a body condition score (BCS) of 2.87, and 648.2 kg of body weight (BW), were assigned to one of the four treatments in a completely ...

Background: In Nigeria decoctions and aqueous extract of Azadirachta indica A. juss (AI), are commonly used in the treatment of malaria. Some women have been observed consuming aqueous extract of AI during pregnancy and lactation because of the folkloric belief that it is potentially harmless. Objectives: There is a paucity of data on the effects of consumption of AI during pregnancy and lactat...

The aim of this study was to investigate the effect herd management practices on milk quality according somatic cell count, standard plate count and electrical conductivity. experimental work carried out at El-Bayoumi dairy farms in Gamasa, Dakahlia Governorate 2016. Managing cows parity, cleanliness score, stocking rate, feeding regime, stage lactation, daily level milking shift had a higher s...

characteristic of the udder, milk traits and their relationship were investigated in 32 awassi ewes raised in a commercial flock. commencing one month after lambing milk yield was recorded at monthly intervals until the ewes were dried. also, the udder traits were measured, including udder width, udder circumference, udder length, distance between teats and length and diameter of both teats. re...

This study approaches the interrelation patterns between composition of milk and whey, curd yield, chromaticity, syneresis, technological quality Manchega sheep using multivariate factor analysis. In addition, effect main husbandry components (flock, prolificacy, season year, stage lactation, parity) on common latent factors that define pattern variation was assessed. For this purpose, 1,200 in...

The effect of milking stimulus on the plasma prolactin concentration of lactating cows and goats was investigated by a radioimmunologic procedure. Plasma prolactin level in seven cows was increased abruptly 1 to 2mins. after the start of milking. On the other hand, the level of the hormone was increased shortly before the onset of milking in two cows at early lactation stage. In the goats at mi...
