Interrelationships among ambient temperature, day length, and milk yield in dairy cows under a Mediterranean climate.
We examined the effect of calving month (CM) on the production of milk and milk protein by Israeli Holstein dairy cows located in the main climatic zone of Israel during their third and fourth lactations, and found it to be significant. Cows that calved in December produced the highest milk and milk protein yields, and those that calved in June produced the lowest, 92.8% of the maximum. The com...
متن کاملOn Predicting Milk Yield and Detection of Ill Cows
The fully automated milking system VMS has different functions which complements the actual milking of cows. This master thesis presents a method to improve the calculation of milk yield in dairy cows for the VMS. This report also investigates if it is possible to improve the algorithm for finding cows with mastitis (udder inflammation). The correctness of the prediction of milk yield is import...
متن کاملPrediction of breeding values for the milk production trait in Iranian Holstein cows applying artificial neural networks
The artificial neural networks, the learning algorithms and mathematical models mimicking the information processing ability of human brain can be used non-linear and complex data. The aim of this study was to predict the breeding values for milk production trait in Iranian Holstein cows applying artificial neural networks. Data on 35167 Iranian Holstein cows recorded between 1998 to 2009 were ...
متن کاملPrediction of 305-day milk yield in Brown Swiss cattle using artificial neural networks
________________________________________________________________________________ Abstract Artificial neural networks (ANNs) have been shown to be a powerful tool for system modelling in a wide range of applications. In this paper, we focus on the capability of ANNs to predict 305-d milk yield in early lactation of Brown Swiss cattle, based on a few test-day records, and some environmental facto...
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...
