Growth Intensity of Lambs during Artificial Milk Rearing Depending on Chosen Non Genetic Factors
The aim of the research was to evaluate the influence of sex, breeding group, litter size and age of lambs when placed in lambing pens for their growth rate during rearing. The average daily gain of lambs was evaluated based on their weighing data each week after their placement into lambing pens. Lambs of Improved Valachian, Tsigai and Lacaune breed (n=26) had been gradually integrated to the ...
متن کاملLife Time Milk Amount Prediction in Dairy Cows using Artificial Neural Networks
This research paper has the use of artificial neural networks for life time milk amount prediction in dairy cows. The study is based on back propagation neural network which has trained and tested based on dataset provided. In modelling the artificial neural networks based predictive model, two-hidden layer network has been constructed. Suitable milk amount predictions can provide farmers and p...
متن کاملApproximating the sheep milk production curve through the use of artificial neural networks and genetic algorithms
This paper examines the potential of a neural network coupled with genetic algorithms to recognize the parameters that define the production curve of sheep milk, in which production is time-dependent, using solely the data registered in the animals’ first controls. This enables the productive capacity of the animal to be identified more rapidly and leads to a faster selection process in determi...
متن کامل"Humanizing" milk: the formulation of artificial feeds for infants (1850-1910).
INTRODUCTION By the middle of the nineteenth century, rates of infant mortality and morbidity in the industrial towns of Britain were a cause of increasing official concern. An article entitled 'The murder of the innocents' in the Lancet of 3 April 1858, encapsulated the problem and its perceived solution. Mortality rates among young children in London, Manchester, Leeds and Birmingham were rep...
متن کاملShort communication: artificial ultraviolet B light exposure increases vitamin D levels in cow plasma and milk.
The number of dairy cows without access to pasture or sunlight is increasing; therefore, the content of vitamin D in dairy products is decreasing. Ultimately, declining vitamin D levels in dairy products will mean that dairy products are a negligible source of natural vitamin D for humans. We tested the ability of a specially designed UVB lamp to enhance the vitamin D3 content in milk from dair...
