Forecasting annual milk yields

Agricultural Meteorology, 1968
Abstract Forecasts of the annual (April–March) milk yield of recorded herds in England and Wales can be made nine months ahead, at the end of June, using April–June milk production data and the June rainfall, with a mean percentage error of 0.31. Eleven months ahead, forecasts can be made, using the April production data, with a mean percentage ...

The cell count of milk in relation to milk yield

Journal of Dairy Research, 1978
SummaryQuarter-milk cell counts and milk yields from 1000 cows in the province of Noord-Brabant were obtained over a 12-month period. The data from 933 animals, mainly heifers, were used to examine statistically the relationship between cell counts, as a criterion for sub-clinical forms of mastitis, and milk yield.

Milk Yield and Disease

The Bovine Practitioner, 2019
The purpose of our research is to develop a comprehensive economic model to assist dairy producers when making treatment and culling decisions. To make profitable decisions, the producer must account for factors including age, production level, stage of lactation, pregnancy status, and disease history. Establishing the interrelationships among disease,

Relationship between Milk Acetone and Milk Yield in Individual Cows

Journal of Veterinary Medicine Series A, 1994
SummaryCorrelations between acetone in milk and milk production during the first nine weeks postpartum were calculated in ten individual cows and for a whole herd. The decrease in milk production due to ke***tonaemia was evaluated using a mathematical model of the KaleidaGraph™ intergrate area program.

Some factors affecting milk yield

The Journal of Agricultural Science, 1923
(1) The variation of the total yields according to the month of calving is given, and causes for this variation are suggested from the mean lactation curves of cows calving in each month.(2) A curve showing the effect of pregnancy on the lactation yield has been prepared and corrections are given for different lengths of service periods after calving ...
