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.

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.

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.

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.

Lupins In Western Australia. 4. Composition And Feeding Value Of The Seeds, John Sylvester Gladstones

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

PREVIOUS articles in this series have discussed the varieties of lupin available in Western Australia, and their cultivation.

This article deals with the composition and feeding value of the seeds.

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.

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.

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.

Choosing Your Lambing Time, T Marshall

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

SHEEP, pastures and labour are the major resources of the sheep enterprise but their productivity is greatly affected by the timing of operations associated with them.

This article discusses how the lambing time can be chosen to get maximum use from each resource.

Emergency Chlorination Of Farm Water Supplies, H C. Hughes

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

TOWARDS the end of summer (and especially in a drought) the risk of water in dams, soaks, wells or tanks becoming polluted is increased.

Bore water is much less likely to be affected unless the bore is poorly sited near a farm building, such as a shearing or milking shed, a pig pen, or a septic tank system.

Lupins In Western Australia. 5. The Grazing Value Of Green And Mature Lupins, John Sylvester Gladstones

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

WHETHER or not lupins are grown primarily as a grain crop, grazing of standing crops and harvested stubbles will continue to be an important use. This article examines the uses of sweet lupins for forage, and the main problem of lupin grazing, lupinosis.

Look After The Tail Enders, B R. Beetson

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

IN Department of Agriculture drought feeding trials last summer, shy feeders lost weight and died while the bigger sheep grew fat. When drafted off and fed separately the shy feeders ate their share and survived the summer.

Urea Or Grain Supplements For Stubble?, H E. Fels

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

Three methods of supplementing sheep grazing stubble were compared at Merredin Research Station in 1970. The stubble used in the experiment was left after harvesting a nine-bushel crop of Gamenya wheat which was a weed-free second crop on new land. The land had never been sown to legumes.

Effects Of Diet And Stress On Gastric Lesions In Albino Rats And Guinea Pigs, Naomi Mckenzie

Loma Linda University Electronic Theses, Dissertations & Projects

Studies were conducted to (1) investigate whether any protective factor is present in fresh water-cured olives or fresh cabbage as compared with the heated supplements against stress-induced gastric lesions in rats maintained on a nutritionally adequate diet for six weeks, (2) determine the relative protective factor in water-cured olives as compared with cabbage, (3) study the effect of black pepper in combination with fresh cabbage and olives and heated cabbage and olives in rats that were fed the same nutritionally adequate diet, and (4) investigate the effects of the same dietary components—cabbage and olives--on histamine- induced gastric lesions in guinea …

Three Beef Raising Systems For Butterfat Producing Properties, Department Of Agriculture, Western Australia

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

THREE-QUARTERS of the calves born in autumn on butterfat farms are not required as milking replacements and are thus available for beef production or immediate sale, at about $20 a head.

The profit from selling beef must be compared with that from selling excess calves off their mothers.

Such a comparison is being made by Department of Agriculture Beef Research Officer D. J. Barker in a series of trials at Bramley Research Station, Margaret River.

Sheep : Experimental Basis For Urea Feeding Recommendations, Department Of Agriculture, Western Australia

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

Recent scientific reviews have concluded that in spite of the great number of experimental observations recorded throughout the world there is no evidence yet to prove that urea can be used profitably for sheep on low quality roughages in genuine grazing conditions.

An experiment is in progress at Merredin Research Station this season, especially designed to demonstrate a response to urea by sheep grazing wheat stubbles, if such a response is possible.

Experiments With Urea On Private Farms, R J. Parkin, G. Palmer, A. Haagensen, L. D. White, R. J. Suiter, H. E. Fels

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

Many District Advisers have carried out trials on private farms to test the response to a variety of types of supplementary feeds. This report gives brief details of five such experiments carried out with urea supplements over the last five years. Table 1 summarises the details and results of these trials.

Thirteenth Random Sample Laying Test : 1969-70, Department Of Agriculture, Western Australia

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

Urea Mixture Formulations, H E. Fels

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

This experiment was done once the experiment above (Urea or Grain Supplements for Stubble) had shown definite but uneconomic responses to a particular mixture of urea, molasses and minerals. The aim was to find whether the response depended on the content of various portions of the mixture, and whether the response to the "shotgun" lick could be explained by the presence of salt, sulphate or cobalt.

The Effect Of Exercise On Metabolic Rate With Time In Overweight And Normal Weight Subjects, Roberta Jewell Keswick

Loma Linda University Electronic Theses, Dissertations & Projects

Previous studies in the Lome Linda University laboratory showed that obese subjects on an exercise program lost approximately one pound more per week as compared to a non-exercise group. Energy expenditure calculations of the exercise did not account for the total caloric deficit required to lose the additional pound. The present study was designed to investigate changes in BMR and metabolic rate with time for normal weight and overweight subjects involved in a practical exercise program. The relationship of changes in BMR and metabolic rate in coping with the problems of obesity were also studied.

Fifteen subjects, eight overweight and …

Quantitative Evaluation Of Saponin Content In Du Puits Alfalfa Foliage (Medicago Sativa L.) With Trichoderma, Wang Li-Chun

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Selections in Du Puits alfalfa (Medicago sativa L. ) were evaluated for saponin content. The data obtained from the Trichoderma bioassay were converted to saponin values by regressions and standard curves. It was necessary to adjust the concentration of alfalfa extract in the bioassay so that the saponin content in alfalfa was estimated in that portion of the curve showing a marked response to saponin. A different regression was established for each group of low and high saponin plants of Du Puits alfalfa. The standard curve prepared with extract of Du Puits alfalfa used on the basis of its …

Nutritive Values Of Russian Wildrye, Crested Wheatgrass, And Intermediate Wheatgrass Grazed By Cattle On Utah Foothill Ranges, George W. Mitchell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A comparative index to digestible nutrients was established for Russian wildrye, crested wheatgrass, and intermediate wheatgrass seeded on foothill areas of Utah. The nutritive values of these grasses were compared by the lignin ratio method, the chlorophyllan ratio method, and the in vivo rumen bag process.

Average digestion coefficients computed by the lignin ratio method for dry matter, ether extract, cellulose, and gross energy were highest for intermediate wheatgrass. Protein was more digestible for Russian wildrye. Digestible energy was adequate in all species to meet requirements for late lactation.

Results from the chlorophyllan ratio method were excessively high and were …

Home Mixing Or Purchased Feeds?, P Mcnamara

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

FEED is the largest single cost in pig production, so any saving which can be made will be of major importance.

Hay And Pasture Digestibility Measured In The Laboratory, D N. Tulloch

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

A recently developed " i n vitro" (laboratory) method of determining the digestibility of hay and pastures is giving good results in the Department of Agriculture's Dairy Laboratory.

The Pig's Need For Minerals, N W. Godfrey

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

Only 16 of the one hundred odd chemical elements known are considered to be essential mineral elements for pigs.

As some of these are required in much smaller quantities than others, they are referred to as trace or minor elements, while the remainder are called major elements.

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.

A Comparison Of Methods Of Urea Application At Ajana, M G. Mason, R. J. Parkin, H. Patrick

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

Compared with urea application separate from the seed, urea mixed with wheat seed delayed and reduced wheat germination, and reduced wheat yields, especially at high rates of urea.

Yields were higher where the urea was topdressed immediately before seeding than where it was top-dressed either immediately after, or two weeks after seeding.

Fertiliser Recommendations For Apple Trees, N H. Shorter, J. E. L. Cripps
