OBJECTIVE To investigate the effect of umbilical cord milking on hematological parameters at 6 weeks of age in late preterm neonates. DESIGN Randomized controlled trial. SETTING A tertiary care center of Northern India during 2013-14. PARTICIPANTS 200 moderate to late preterm neonates randomly allocated to early cord clamping or umbilical cord milking group (100 in each). INTERVENTION I...
BACKGROUND Mastitis prevalence, milking procedures and management practices were investigated in 25 big dairy herds supplying milk to an Estonian dairy company. The aim of the study was to provide information for the company to be used in their new udder health improvement program to be set up after the completion of this study. METHODS Quarter milk samples were collected from 3,166 cows for ...
The cleaning and sanitation of milking equipment could be consider a critical point in the milking procedure because a cleaning failure could influence the level of bacteria contamination of bulk tank milk. Aim of the study is to monitor the cleaning procedures of milking systems in 7 dairy cows farms in Lombardy and to find a relation between efficacy of cleaning system and the bacterial quali...
The procedures and practices associated with milking are critically important and people now-a-days are switching over to machine milking to save time and money. Milking equipments if properly maintained have a positive impact on both milk production and milk quality. However, if the equipments are not used as per the recommended standard values it may have some untoward effects on udder health...
The aim of this study is a further characterization of the electrical conductivity (EC) signal of goat milk, acquired on-line by EC sensors, to identify new indexes representative of the EC variations that can be observed during milking, when considering not healthy (NH) glands. Two foremilk gland samples from 42 Saanen goats, were collected for three consecutive weeks and for three different l...
The aim of this study was to develop and test a new fuzzy logic model for monitoring the udder health status (HS) of goats. The model evaluated, as input variables, the milk electrical conductivity (EC) signal, acquired on-line for each gland by a dedicated sensor, the bandwidth length and the frequency and amplitude of the first main peak of the Fourier frequency spectrum of the recorded milk ...
In the past century, great strides have been made toward optimizing milk production efficiency of dairy cows. One of the key findings that has emerged is that the milk yield of dairy cows is responsive to demands of offspring or milk removal; hence, milk production can be increased by frequent milking. Early studies illustrated the galactopoietic effect of frequent milking during the entire lac...
The ability of ruminant mammary glands to produce milk is determined by the number of cells secreting milk and their level of activity. Changes in the number of cells in the udder occur during lactation. It has been shown that mammary cells proliferate during this process, while other cells die through apoptosis. The decline in milk production after peak lactation appears to be due to a gradual...
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...
