Effects Of Mastitis On Milk Yield And Composition, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

EVERY DAIRY farmer knows how much he spends on the treatment of cows affected with mastitis, but the actual loss in production is more difficult to estimate.

As part of the current mastitis research programme the Department of Agriculture's Animal and Dairying Divisions surveyed 37 dairy herds with a believed high incidence of mastitis.

Once Daily Calf Feeding Lowers Rearing Costs, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

The usual method of hand rearing dairy calves involves twice daily feeding of milk or milk substitutes.

This routine adds considerably to the labour necessary at milking time and may have prevented many farmers from putting much effort into dairy beef production.

The report below comes from a 1969 trial carried out at Bramley Research Station to see if once-daily calf feeding was as effective as twice daily feeding.

The trial's results should be considered as early findings from a series of trials being conducted into calf rearing regimes by both the Animal and Dairying Divisions of the Department of …

Dry Supplements Reduce Labour And Cost Of Calf Rearing, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

The conventional method of hand rearing dairy calves in Western Australia calls for the feeding of whole milk, skim milk and/or milk substitutes for periods of up to 16 weeks.

This requirement for milk and labour has often prevented beef production from becoming a major sideline on many wholemilk and butterfat farms.

The two trials reported below* were carried out at Bramley Research Station to see if milk consumption and time to weaning could be reduced by free-feeding hay and cereal based supplements.

Tallow As A Substitute For Butterfat In The Diet Of A Young Calf, R. Sprivulis

Journal of the Department of Agriculture, Western Australia, Series 4

WHILE cow's milk is the best food for a young calf it is also very expensive.

The normal substitute for whole milk is skim milk, but removing the butterfat from cow's milk reduces the dry matter content by 30 per cent and the digestible energy by 50 per cent.

Good Management For The Springers Pays Dividends, J Y. Langdon

Journal of the Department of Agriculture, Western Australia, Series 4

This article gives a striking example of the advantages of calving cows in good and rising condition—and explains why condition around calving time is so important.

ALTHOUGH most farmers know that cows calving in good and improving condition will give higher yields than those calving in poor condition, few use this knowledge to improve the production from their cows.

Mastitis : Prevention And Control. 2. Principles Of Mastitis Control, F C. Wilkinson

Journal of the Department of Agriculture, Western Australia, Series 4

MASTITIS is a major cause of financial loss in over half our dairy herds.

Losses result from treatment costs, milk discarded, permanent loss of milk production, culling, lowering of solids-not-fat content and loss of butter-fat production.

Mastitis CAN be controlled. This article outlines the basic principles of mastitis control in the milking shed.

Skim Milk : The Cheapest Pig Feed, P C. Beck

Journal of the Department of Agriculture, Western Australia, Series 4

BUTTERFAT production has started on most South-West dairy farms, and although pig prices are not high at present, many dairy farmers have either purchased young stock or bred pigs to utilise their surplus skim milk.

Skim milk is the best feed for pigs on the dairy farm. Properly used in conjunction with other feeds it produces high quality carcasses at minimum cost.

Cull Your Dairy Cows On Production, R A. Bettenay

Journal of the Department of Agriculture, Western Australia, Series 4

Good production and breeding records are essential to allow effective culling of dairy cows, says Busselton Agricultural Adviser R. A. Bettenay, B.Sc. (Agric.) in this article, in which he outlines points to take into account when culling the herd.

Pigs On The Dairy Farm : Cutting Costs To Meet Low Prices, R A. Bettenay

Journal of the Department of Agriculture, Western Australia, Series 4

As all dairy farmers know, the market prices of pigs tends to fluctuate, depending on supply and demand, in a manner which is very hard to predict.

At a time when prices are low there are several things which the dairy farmer can do to continue operating, although at a reduced margin.

Some Economic Aspects Of The Fluid Milk Industry Of Nebraska, Kenneth E. Anderson

Department of Agricultural Economics: Dissertations, Theses, and Student Research

Most citizens of Nebraska, especially the dairy farmers who produced milk for city consumption, are currently concerned with the problem of marketing fluid milk.In Nebraska and all over the United States, sales of wholesale milk farmers have been increasing for the past 15 years, while cream sales to creameries have been decreasing.

Production of milk in Nebraska is greatest in the eastern part of the state.Likewise, consumption is concentrated in Eastern Nebraska. This is most likely due to Eastern Nebraska’s highly concentrated population as well as the most favorable farm conditions for dairy cows.

Most of the bottled milk in …

Cooling, Storage, And Transporation Of Milk And Cream, P. A. Downs, F. D. Yung

Nebraska Agricultural Experiment Station: Historical Circulars

The care given milk and milk products should be such that they will be relished by young and old alike. Greater use of milk can be encouraged by serving fresh milk cold. Cooling of milk also insures a fine product several hours after production. This is important not only for milk that is to be used, but for milk or cream that is to be sold.

Economic Aspects Of Contagious Abortion In A Dairy Herd, Department Of Animal Husbandry

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The object of this study is to present the measurable losses due to abortion in a dairy herd of high-producing ability over a period of approximately one-third of a century. The records available provide a rather complete history of what has taken place.

Selection, Breeding, Methods Means More Milk, H. P. Davis

Nebraska Agricultural Experiment Station: Historical Circulars

Milk good cows. It pays if you know how. Good dairy cows will always make money. Scrub, poor, or common cows never bring a good profit and usually cause a loss. Why waste feed and labor on inefficient producers, the kind that never make a satisfactory profit? Join a cow testing association. Let the tester keep books on your cows and let the milk scale and the milk sheet point out the money makers. Improvement comes only from selection and breeding.

Feeding The Dairy Cow, H. P. Davis

Nebraska Agricultural Experiment Station: Historical Circulars

Cows produce milk from feed and water only. Therefore feed in proper quantity and quality is usually the limiting factor governing a cow's production up to the limit of her capacity.

Dairy Calf Care And Management, H. P. Davis, R. F. Morgan

Nebraska Agricultural Experiment Station: Historical Circulars

Calf raising begins before the calf is born. A cow that is healthy and in good physical condition will, in all probability, drop a strong, vigorous calf. The feeding and care of the cow before calving is therefore of the greatest importance for the future development of the calf.

Better Sires -- Better Stock: Build Better By Breeding, H. P. Davis

Nebraska Agricultural Experiment Station: Historical Circulars

Economy and logic indicate that the most satisfactory method of obtaining higher-yielding dairy cattle is to breed them. Nebraska raises the feeds - corn, oats and alfalfa - that will grow dairy cattle and can raise them as cheaply as any region. The method is simple. Use purebred dairy sires on the present cows. By the use of good purebred dairy sires great improvement can be obtained in a single generation.

Purebred Sires Effect Herd Improvement, M. N. Lawritson, J. W. Hendrickson, W. B. Nevens

Nebraska Agricultural Experiment Station: Historical Circulars

The real worth of a sire for the dairy herd can be established only when production records of the progeny are available for comparison with those of the preceding generation. A study of the following three sires which have been in service in the University of Nebraska dairy herd should be of interest to the Nebraska dairyman wishing to improve his own herd. This experiment indicates that the apparently high cost of a good herd sire is more than outweighed by the increase in the value of the progeny.
