Veterinary Consultancy Boosts Piggery Profits, Ashley Mercy

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

A pilot Pig Herd Health Management Scheme co-ordinated by the Department of Agriculture has stimulated much increased involvement of veterinarians in the Western Australian pig industry. Co-ordinated by Ashley Mercy, principal veterinary officer (epidemiology) horn 1985 to 1989, the scheme demonstrated the value of having regular visits from veterinary consultants and in implementing programs to prevent disease and production problems occurring in herds.

A two-year study tested the hypothesis that growth rate interacts with bull exposure to influence age at puberty in heifers. Heifers exposed to sterile bulls and fed to achieve a high growth rate (1.8 lb/day) attained puberty 73 days earlier than heifers not exposed to bulls and fed to a moderate growth rate (1.3 lb/day). Heifers exposed to bulls and fed to achieve a moderate growth rate attained puberty at ages similar to heifers not exposed to bulls and fed to a high growth rate. Furthermore. heifers receiving these two treatments attained puberty 23 days earlier than heifers not exposed …

Weighing steers three consecutive days at the beginning and end of the trial reduced variation and increased the probability of detecting a difference in daily gain and gain/protein ratios between treatments when compared to a standard weighing method (once at the beginning and once at the end of the trial). Regressing 1 initial, 1 final and 11 weekly weights also decreased variation and increased the probability of detecting treatment differences compared to the standard method, but was more variable than using three weights at the beginning and end of the trial.

Young, growing steers and lambs supplemented with natural protein …

Retail value of wholesale meat cuts is influenced by quality and the proportion of lean, fat and bone. Wholesale cuts vary widely in value; for example, loins and ribs sell for more than rounds, rounds more than chucks, and chucks more than flanks, plates, or briskets. This value difference has prompted many attempts to find breeding and feeding systems that will increase the proportion of high-priced cuts.

Results shown here characterize the composition of carcass wholesale cuts from 14 breed combinations that were part of a cattle germ plasm evaluation program at the U.S. Meat Animal Research Center, Clay Center, …

Ryegrass Disease Could Spread, Department Of Agriculture, Western Australia

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

The disease annual ryegrass toxicity kills sheep and cattle grazing pastures which contain infected annual ryegrass. In Western Australia the first confirmed outbreak was in 1968 in the Gnowangerup area.

The disease has noe spread over a range of 450 kilometres and with a total area of perhaps 100 000 hectares. because annual ryegrass is the major sown pasture grass in W.A. the disease could spread throughout the South-West.

There are some precautions that can be taken.

Calcium And Phosphorus Requirements In Lupin Seed Rations For Pigs, N W. Godfrey, A. R. Mercy

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

Seed of lupin varieties now available can be combined with wheat or barley to produce a balanced diet for growing/finishing pigs, and lupin seed has become a popular ingredient of pig rations.

As a protein concentrate, lupin seed is a satisfactory alternative to meatmeal, provided adequate amounts of calcium and phosphorus are added as supplements. Without the addition of these elements to rations of lupin seed and grain, a number of problems are likely to arise.

Trials at the Medina Pig Research Station have shown that Christmas Island rock phosphate is the cheapest and most convenient source of supplementary calcium …

The Sheep Measles Control Programme, J B. White

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

In the first seven months of 1968 Australia exported to the United States 17 747 tons of boned mutton; of this 2 198 tons, or 12.4 per cent, was condemned on arrival in that country.

The main cause of rejection was the presence of Cystkercus ovis cysts, the intermediate stage of the tapeworm Taenia ovis, of which the definitive host is the dog.

In 1969 the Western Australian Department of Agriculture decided to study the epidemiology of this disease.

This was the beginning of the work which would evolve into the 'Three Shire Control Programme'

The use of high concentrate rations in finishing cattle has led to a rather high loss of livers due to abscesses.

The 1967 Statistical Summary of the Federal Meat Inspection Service of the USDA indicated the total number of cattle inspected was 27,859,980. Of these, 9.6% were condemned because of liver abscess. Considering the value of a liver to be about $3, the estimated loss to the industry because of condemnatIon due to abscess would be over $8 million annually.

The incidence of liver abscesses increases as the roughage level in a finishing ration decreases below 5% (Table I). The …

Oral feeding of stilbestrol or implanting with stilbestrol or Synovex has resulted in increased weight gain and efficiency of gain for cattle fed finishing rations.

Combining oral feeding or stilbestrol with implanting did not give increased performance above that obtained from oral stilbestrol alone in two tests. Implanting cattle fed oral stilbestrol at the start of the feeding program with either stilbestrol or Synovex gave a similar pattern of performance to that obtained from oral stilbestrol alone.

Many beef cattle breeders in the United States and other countries are following the progress of the selection experiment at the Fort Robinson Beef Cattle Research Station, Crawford, Nebraska. Three lines of Hereford cattle from the same genetic foundation are under selection. Line 21 is selected for 200-day weight. Line 22 is selected for yearling weight. Line 23 is selected for an index combining yearling weight and a score for muscling and fat thickness.

Each line is operated as a closed herd so it will be possible to determine how much improvement in economic traits can be made by selecting …

Beef carcass evaluation work is designed to obtain production and carcass data on bulls, steers and heifers. One objective is to evaluate sex effects on growth and carcass traits. Another is to determine if sires rank the same in growth and carcass traits on their bull, steer and heifer progeny.

Preliminary results from the 1963 slaughter groups were reported in the 1964 Beef Cattle Progress Report. This report covers averages of 1963 and 1964 results. Results both years were similar.

Efficiency of sugar beet farming can be improved by feeding beet top silage to livestock.

In two recent trials at the Scotts Bluff Experiment Station lambs fed unwilted beet top silage as the only roughage gained significantly faster than lambs fed corn silage.

Amounts of concentrates were comparable (Nebraska Experiment Station Quarterly, Fall, 1962).

This experiment compared the feeding value of a complete mixture of unwilted beet tops and concentrate added at the time of ensiling, with beet top silage and concentrate handled separately. A conventional corn silage and concentrate ration was used as a control.

Results showed that a …

Shipping fever is a respiratory disease "complex" of cattle. The disease causes extensive economic losses from death, loss of physical condition, inefficient feed utilization and treatment expense. The annual loss from this disease in the United States has been estimated to be $25,000,000.

In many respects shipping fever is similar to respiratory diseases of humans. It may occur in any season of the year, but is most common in the fall and early winter. Although any age animal may be infected recently weaned calves and feeder cattle which have just been moved from the range to feedlot are most susceptible.

Feeding pastured calves protein supplements weekly instead of daily during the winter made little difference in either winter or summer gains, according to research results to date.

Two sources of protein were used in the trial. (I) Second cutting alfalfa hay was fed at the rate of four pounds per head daily. One group of calves was fed four pounds per head daily and one group was fed 28 pounds per head once each week. (2) Forty percent protein, pellets or cake, was fed at the rate of one pound per head daily. One group was fed one pound per …

The science of nutrition has come into its own in the last few years. Greater recognition of the value of protein, the identification of new nutrients and the awareness of the importance of nutrition to health have been part of this trend.

In this new era in nutrition, beef has been found to be one of our most nutritious foods. Not only does it contain a generous amount of protein, but its protein is of high quality, too. In addition, beef supplies important minerals such as iron and phosphorus, which contribute to healthy blood and sturdy bones. The essential B …

Swine Brucellosis: How You Can Eradicate It

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Swine brucellosis is a bacterial disease that affects swine, other domestic animals, and humans. Severe exposure causes the disease in cattle, dogs, cats, and poultry. The disease can spread from one species of animal to another, and from animals to humans. However, it does not normally spread from one human to another, or from humans to animals. The disease costs the swine industry about $10 million a year. Losses due to human infection cannot be estimated. Although human brucellosis, or undulant fever, is difficult to diagnose-especially in mild cases-a total of 892 cases were documented in the United States in …

48th Annual Feeders Day Progress Report: Improving Beef Production Through Nutrition And Management, W. V. Lamber, E. F. Frolik

Nebraska Beef Cattle Reports

As we start a new decade it is appropriate to ponder for a moment on where we have been and where we go from here.

The past ten years have seen significant changes in all phases of animal agriculture. Probably the most spectacular changes came in the area of nutrition. During the past ten years significant advances were made in our knowledge on mineral and vitamin nutrition. Additional facts on the old problem of the ratio of concentrates to roughage have been added. Ways of supplementing poor quality roughage to obtain optimum production were learned.

Leaflet No 1002 - Swine Paratyphoid (Salmonellosis Necrotic Enteritis), C R. Toop

Bulletins 1 - 2999

Paratyphoid is an infectious disease of pigs which is likely to make it appearance wherever pig raising is practised.

It may occur in an acute septicaemic form which is often rapidly fatal and accompanied by serious mortality and in a sub-acute or chronic form known as necrotic enteritis which is characterised by unthriftiness and scouring. The out breaks occurring in Western Australia are principally of the acute type and they are usually associated with the introduction of pigs from saleyards.
