Feeding And Care Of The Farm Dog, J B. White

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

Most farmers acknowledge the value of a well trained dog when handling sheep, but few appreciate that without correct care and feeding such a dog may reduce their profits and constitute a hazard to the health of themselves and their families.

The New Stock Diseases Regulations : A Summary Of Major Regulations Under The New Stock Diseases (Regulations) Act, M R. Gardiner

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

THE new Stock Diseases (Regulations) Act proclaimed on August 1, 1970, introduces some new regulations and makes many changes to existing regulations, which could affect most farmers at some time or another.

This article summarises the regulations most likely to affect farmers, with emphasis on new or changed regulations.

Cysticercus Ovis : Sheep Measles, G C De Chaneet

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

CYSTICERCUS OVIS, commonly known as sheep "measles", has come into prominence in the last few years because of the rejection of affected carcasses by overseas markets. Recently it was one of the causes of a complete ban on imports of Australian mutton by-the.iJnited States and Canada.

Phosphate Applications Affect The Coumestrol Level Of Medics, T Marshall, R. J. Parkin

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

Western Australia has a million acres of medics including various cultivars of barrel medic, Medicago truncatula, and strand medic, M. littoralis. Both species contain coumestrol, a chemical thought to have caused delayed conception and reduced twinning rates among grazing ewes in New Zealand.

No infertility has been reported among ewes grazing medic pastures in Western Australia, but coumestrol levels in both species have often been high enough to suggest the possibility of oestrogenic responses among sheep grazing them.

A Control Programme For Cheesy Gland In Sheep, M R. Gardiner

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

CASEOUS LYMPHADENITIS, or "cheesy gland" as it is usually known in Australia, is a common disease of sheep which is very important in the economics of the lamb and mutton industry.

White-Tailed Deer In Southeastern Minnesota: Winter Observations, Robert D. Dorn

Journal of the Minnesota Academy of Science

Food habits, movements, vegetation type use, and bedding of white-tailed deer (Odocoileus virginianus borealis) were observed while snow-tracking in southeastern Minnesota. Waste corn (Zea Mays) was the most important food item. Three dogwoods (Cornus racemosa, C. rugosa, C. alternifolia), all non-commercial forest species, were the most important for browse. Acorns were unavailable due to crop failure. Six trails made in less than 24 hours covered more than 1 mile each, straight line distance. The longest was 31/s miles. Snow did not appear to affect movements. About two-thirds of the beds were on wooded uplands. Browsing areas appeared dependent on bedding …

Looking At Wolves As Scientific Subjects Rather Than As Storybook Villains, John Mcclung

Journal of the Minnesota Academy of Science

Minnesota researchers, attempting to separate objective data about timber wolves from emotional attitudes, are compiling information gathered over a period of several years in the state's north woods. Findings suggest that laws to protect and preserve this animal may be as necessary as programs to control predations on deer or domestic livestock.

Survival Of Hand-Reared Mallards (Anas Platyrhynchos) On Artificial Farm Ponds, Lawrence L. Thomforde

Journal of the Minnesota Academy of Science

The survival of hand-reared, game-farm mallards released on artificial farm ponds was studied in Goodhue County, Minnesota. Of the 300 ducklings released each year from 1965 through 1967, an average of 45 per cent survived until most were capable of flying. More ducklings survived when released on ponds fenced from livestock than on unfenced ponds. Grazing livestock severely reduce cover vegetation around unfenced ponds. A total of 3.7 per cent of the bands were recovered. The first year recoveries represent 64 per cent of all the bands reported. Thirty-nine per cent of the band recoveries occurred within 15 miles of …

Movement Of Franklin's Ground Squirrel Into Northeastern Minnesota, Jerome D. Robins

Journal of the Minnesota Academy of Science

Specimens of Franklin's ground squirrel have been obtained in several localities in St. Louis County, Minnesota. The movement of this prairie-dwelling rodent into the montane coniferous forest region of northeastern Minnesota may be related to recent man-made changes in the habitat.

Rationing Standing Crops To Sheep, H E. Fels

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

This experiment was done at Merredin Research Station to develop and test a method of rationing standing crops to sheep, and also to find whether rationing would reduce the sheep's water consumption.

The experiment involved 60 sheep on 12 one-acre plots of drought affected Gamenya wheat.

Hydatid Disease In Western Australia, G C De Chaneet

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

BECAUSE hydatid disease is a disease of humans as well as animals, every dog owner should be aware of the conditions that perpetuate hydatids and the methods of control.

The incidence of hydatids in Western Australia in the past has not been high.

However, the increase in sheep numbers over recent years, together with the intensification of farming methods, may lead to a rise in incidence unless stock owners, particularly sheep farmers, take steps to control the disease.

Surplus Cereal Crops For Sheep Feed, H E. Fels

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

SINCE the introduction of wheat quotas many farmers have considered feeding unsaleable grain to sheep.

The three alternative methods of feeding this grain to sheep are

• as standing crops

• as grain supplements, fed in the paddock

• as grain plus hay, in a feedlot.

Influence Of Urea On The Fermentation Pattern & Nutritive Value Of Corn Silage, John Shirley

Masters Theses & Specialist Projects

The effects of chemical additives on the fermentation pattern and subsequent feeding value of corn silage was investigated over a two year period. Corn plants harvested in August 1967 (Experiment I) were ensiled with no additive, 3.50 per cent area, or urea-mineral mix supplying an equal amount of urea. Those harvested in August 1968 (Experiment II) were ensiled with no additive, 0.50 per cent urea, or 0.75 per cent urea. The nutritive value of these silages was evaluated chemically and by lactation trials.

:he addition of urea alone, or in combination with minerals elevated the initial pH and buffered against …

Crop Rationing : A Useful Drought Feeding Technique, H E. Fels

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

A TRIAL carried out during the 1969 drought demonstrated that rationing standing crop is a practical method of feeding it to sheep when feed is scarce.

Rationing will be mainly a drought feeding technique for that part of the crop which will definitely be used as sheep feed. Crop that may or may not be needed for sheep would normally be harvested and the grain kept as a contingency allowance.

Bats Of The Genus Myotis From Western Mexico, With A Key To Species, J. Knox Jones Jr., Hugh H. Genoways, Larry C. Watkins

University of Nebraska State Museum: Mammalogy Papers

Distribution and variation in Mexican representatives of the vespertilionid bat genus Myotis have not been well documented. The most complete modern systematic treatment of these bats is that of Miller and Allen (1928), although these authors examined relatively few specimens and some of their taxonomic conclusions have been modified by more recent studies (see especially Findley, 1960; Findley and Jones, 1967; Genoways and Jones, 1969). In the past two decades, field representatives of the Museum of Natural History at The University of Kansas have obtained large collections of mammals in western Mexico, principally in the states of Jalisco and Sinaloa. …

Influence Of Dietary Supplements Of Cholesterol And Vitamin D On Certain Components Of The Blood And Body Of Growing-Finishing Swine, M. H. Jurgens, E. R. Peo, Jr.

Department of Animal Science: Faculty Publications

The American public has been made extremely conscious of the concept that saturated fat and cholesterol may be involved in atherosclerosis in man. Likewise, because of their content of cholesterol and saturated fatty acids, animal products have become engrossed in a controversy concerning their role in the atherogenic process. No definite conclusions have been made in this area and until further research advances in the field of atherosclerosis, the animal scientist may have to concern himself with modifying the animal product in such a way that it will be more acceptable to the American public. The degree to which this …

A Summary Of Intergeneric New World Quail Hybrids, And A New Intergeneric Hybrid Combination, Paul A. Johnsgard

Papers in Ornithology

The exceedingly close affinities of the quail genera Colinus, Callipepla, and Lophortyx have been recognized for some time and have recently been emphasized by additional morphological (Holman 1961; Hudson et al. 1966), biochemical (Sibley 1960), and pterylographic (Ohmart 1967) evidence. Indeed, Holman has suggested that these three taxa might best be regarded as subgenera. Phillips et al. (1964) pragmatically merged Lophortyx with Callipepla; and Delacour (1961-1962) synonymized not only Lophortyx, but also Oreortyx and Philortyx, with Callipepla, yet retained Colinus as a separate genus. Although Ohmart (1967) questioned the validity of generically separating Lophortyx and …

Control Of Hide Beetles, Department Of Agriculture, Western Australia

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

SKIN and hide beetles, members of the Dermestid beetle family, can cause serious damage to hides and skins.

British authorities are particularly concerned with the incidence of hide beetle infestation in sheepskins imported from Australia.

Local graziers and country abattoirs should pay attention to this problem as damage by hide beetles can greatly reduce the value of all types of skins.

High Pre-Mating Liveweights Improve The Lambing Performance Of Merino Ewes, R J. Suiter

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

Analysis of lambing trials with Merino ewes has shown a highly significant association between pre-mating liveweight and lambing performance.

With May-June lambing ewes there was a 2.9 per cent, lambing increase for every extra 10 lb. liveweight; for July-August- September lambing ewes there was a 6.9 per cent, increase for every 10 lb. liveweight increase.

With the May-June lambing there was a critical weight below which twinning was negligible.

Maintaining Ewe Bodyweight For A Late Mating, T Marshall

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

DEPARTMENT OF AGRICULTURE experiments have indicated that the bodyweight of ewes at mating can have a large bearing on lambing performance.

It appears that for every 10 lb. increase in pre-mating bodyweight, an increase of some 3 to 6 per cent, lambs born could be expected, depending on the lambing time.

Supplementing Calves With Tallow : Results Of A Trial At Wokalup Research Station, Department Of Agriculture, Western Australia

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

THE removal of butterfat from milk by separation, reduces the energy content of the milk by about 50 per cent., and must slow the growth of calves unless extra energy is provided from some other source.

In the dairying districts of Western Australia, there has been considerable interest in recent years in the addition of homogenised tallow to skim milk to provide extra energy.

Good calves have been produced by this means.

Prime Lamb Production In Western Australia : A Review Of The Development Of The Prime Lamb Industry In Western Australia, R J. Suiter

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

PRIME LAMB production in Western Australia has evolved into an industry based almost entirely on the local market.

This has not always been the case. In the 1930-40 era a substantial proportion of the State's prime lamb production was exported to the United Kingdom.

During this era the industry was equally dependent on exports and local market.

Carrying Prime Lambs Through Summer, R J. Suiter

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

The annual lamb glut in September- October has caused many farmers to show interest in feed lotting and other methods of carrying over prime lambs for a higher priced market.

Unfortunately however, little information has been available on the necessary techniques under Western Australian conditions.

This report presents the results of the first year of a trial being conducted at Chapman Research Station to examine some of the problems associated with carrying lambs through the summer for later marketing.

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.

Urea Block Supplements For Stubble, H E. Fels, R. J. Parkin

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

THERE was a great deal of controversy throughout the summer of Western Australia's 1969-70 drought over the feeding of supplements other than grain to grazing sheep.

This report summarises some of the experiments carried out by this Department to investigate various artificial means of supplementing sheep grazing stubbles and dry summer pastures.

Further details of the experiments can be obtained by contacting the authors.

The results failed to demonstrate economic responses to urea supplements for grazing sheep.

The Feed Year Approach To Dairying, P T. Arkell

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

Dairy cows have different food requirements at different times of the year.

Cows in peak production require much more food per day than dry cows. It is a waste of money to feed a dry cow more than it actually needs for maintenance.

Equally, it is uneconomic NOT to feed a producing cow enough to give maximum production.

1970 Nebraska Beef Cattle Report, J. L. Adams, E. F. Frolik, H. W. Ottoson, F. E. Eldridge

Nebraska Beef Cattle Reports

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 …

Effect Of Feeding-Fasting Interval On Finishing Pigs: Weight Gain, Feed Utilization And Physical And Chemical Carcass Measurements, T. L. Veum, W. G. Pond, L. Dale Van Vleck, E. F. Walker Jr., L. Krook

Department of Animal Science: Faculty Publications

Thirty-two Yorkshire pigs (49 kg body weight, 108 days of age) were used to determine the effect of feeding-fasting interval on rate of body weight gain, feed utilization and carcass and organ measurements at a slaughter weight of approximately 90 kilograms. Treatments were: (1) Continuous ad libitum feeding,(2) ad libitum 1 day, fasted on alternate days, (3) ad libitum 1 day, fasted 2 days, (4) ad libitum 1 day, fasted 3 days. Average daily gain was reduced progressively as severity of the fasting-feeding interval was increased. Efficiency of feed utilization, likewise, was reduced as the severity of feed restriction increased, …
