Objective To investigate the safety of umbilical cord milking on both the mother and neonate among very preterm deliveries of less than 33 weeks of gestation. Methods Pregnant women who were expected to deliver at between 24 0/7 and 32 6/7 weeks of gestation were randomized to either the umbilical cord milking or immediate cord clamping group. Maternal and neonatal data associated with delive...

M i l k i n g cows three times a day ( 3 x 1 to increase production is not a new idea. The practice has been confined mainly to purebred herds, but with rising costs for facility expansion, increases in labor efficiency through mechanization, and higher herd average production levels, 3X milking may be worth considering as a long-term strategy for many commercial herds. While it may seem inappr...

The introduction of new technology, management practices, and alternative production systems has resulted in rapid structural change in the US dairy industry. This paper examines adoption rates and adopter characteristics for the following dairy technologies, practices, and systems: holding pen with an udder washer, milking units with automatic take-offs, genetic selection technologies, recombi...

A basic principle of animal production is that individual performance is determined by genetic makeup and environmental conditions. Accordingly, individuals with above average phenotypes can result from superior genotypes, favourable environments, or both. Prior to weaning, it is the prenatal and then milking and mothering ability of the dam that provides an important component of a young anima...

We investigated the effects of omitting one or two milkings weekly on milk yield and milk composition in dairy sheep. Ninety Spanish Assaf ewes were allocated to three experimental treatments: T0 (no milking omission; 14 milkings/week), T1 (omission of one evening milking per week; 13 milkings/week) and T2 (omission of two evening milkings per week; 12 milkings/week). The experiment was extende...

The milk production of dairy goats under various regimes of mother-young contact from day 4 post partum were studied during the first 2 months of lactation, together with the prolactin (PRL) and growth hormone (GH) responses to udder stimulation. In the control group, 13 goats and their kids were left in permanent contact and did not undergo milking. In two additional groups, goats were machine...

It is a requirement as part of the safety evaluation of novel compounds, which are intended to be administered to pregnant women or women with young children, that the potential for the compound or its metabolites to be transferred from a dam to its litter during lactation is measured. The data obtained from the rat milking studies are also used to support the rat peri- and post-natal studies. ...

The aim of this review is to better understand the regulation of milk yield in response to once-daily milking and feed restriction. Glucose is the principal precursor for the synthesis of lactose (a major osmotic agent in milk), and participates in determining the milk volume produced. When applying these two breeding factors, reductions in milk yield are associated with a reduction in milk lac...

Colostrum formation and lactogenesis in the mammary gland and the timing of parturition are regulated by endocrine signals. Changes in progesterone (P4) and prolactin (PRL) are considered key events that inhibit colostrum formation, trigger parturition, and signal the onset of lactation. The goal of our study was to determine if colostrum yield and composition and immunoglobulin transfer are af...

BACKGROUND Animal-derived allergens include lipocalins which play an increasing role in occupational respiratory sensitizations. The prevention of sensitization in stock farming is often difficult due to intense exposure, with traditional milking still requiring close animal contact. Complete avoidance of allergen exposure is only possible if stock farming is abandoned. This is, however, often ...
