The lactating tammar wallaby progressively alters the rate of secretion and composition of its milk to provide appropriate nutrition for the developing offspring, whose needs are signalled by changes in the pattern and efficiency of its sucking. Tammars are also capable of asynchronous concurrent lactation, when the mother provides a dilute milk for a newborn young permanently attached to the t...

BACKGROUND Milk ejection is a transient episode critical to milk removal and women typically have multiple milk ejections during breastfeeding and pumping. Recently it was found that milk ejection characteristics such as number of milk ejections and periodicity were consistent throughout 12 months of lactation in women who expressed their milk with an electric breast pump. It is not known wheth...

The objectives were to determine the effect of administering recombinant bovine ST (bST) every 14 d on milk yield and milk composition in dairy ewes and to assess the possible effects of treatment on milk yield loss that occurs at lamb weaning. Seventy-two lactating dairy ewes were separated into 4 groups at lambing, and each group received no bST (control) or 40, 80, or 120 mg of bST every 14 ...

The effects of fat supplementation and weaning system on commercial milk yield and milk composition were determined on 129 East Friesian crossbred ewes. Prior to lambing, ewes were randomly assigned to one of two weaning systems. The DY1 system involved weaning of ewes from their lambs within 24 to 36 hr post-partum and then twice-daily machine milking. In the MIX system, ewes had access to the...

Cow milk, a highly nutritious food item, is amenable to quality degradation due to lipolysis and proteolysis, as a sequel to the growth of spoilage microorganisms, particularly under ambient condition in tropical countries, with consequential loss of aesthetic appeal and product output. Prescription antibiotics used for milk preservation have many undesirable side effects on the health of consu...

AIM The present investigation was conducted to study the association between udder morphology and in vitro activity of milk leukocytes in high yielding crossbred cows. MATERIALS AND METHODS A total of 48 healthy high yielding crossbred cows were selected for the study. The udder configuration and teat/udder morphology were recorded before milking. Milk samples (100 ml/cow) were collected asep...

background: lactoperoxidase (lpo) is one of the most heat-stable enzymes in milk and its inactivation has been proposed for monitoring thermal processes. the aim of this study was to provide information on activity and thermal inactivation behavior of lpo in iranian cow and buffalo milk and whey. methods: sixty cow and buffalo milk samples were collected. the lpo activity was measured using spe...

The influence of milk yield and milk composition on the diagnosis of Mycobacterium avium ssp. paratuberculosis (MAP) by milk ELISA in the context of the total IgG secretion patterns in milk throughout lactation and serum concentrations were investigated. A 2-yr trial was performed in which 1,410 dairy cows were sampled monthly and MAP milk ELISA status and milk yield and composition were determ...

introduction: there are a lot of fungi in the air and our environment that grow and reproduce if the temperature and humidity are suitable. aspergillus flavus and parasilicus are among the most important food contaminants which have a role in food poisoning. these fungi secrete poisons which contaminate animal feed as well as the milk we get from the animals fed with these foods. methods: in th...
