The Effect Of Natural Antioxidants On Conjugated Linoleic Acid Yield During The Photoisomerization Of Soy Oil Linoleic Acid, Camille Schaffner, Andy Proctor

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Dietary conjugated linoleic acid (CLA) is known to be effective in avoiding many obesity related diseases. Conjugated linoleic acid is a product of ruminant fermentation and 3.4 g/day are needed to obtain the clinical benefits. However, it is difficult to obtain sufficient CLA to realize these benefits from a healthy diet containing dairy and beef products, without increasing levels of dietary cholesterol and saturated fat. A 20% CLA soy oil with low saturated fat and no cholesterol has been produced by photoisomerization of linoleic acid in the triacylglyceride oil. Further increasing the CLA yields has been possible by addition of …

Caring For Compromised Cattle: Assessing Animals At Risk

Nebraska Beef Quality Assurance Program

Cattlemen have long recognized the need to properly care for their livestock. Sound animal husbandry practices – based on research and decades of practical experience – are known to impact the well-being of cattle, individual animal health and herd productivity. There is no doubt that producers work hard to ensure that their cattle are properly cared for throughout all stages of production. Unfortunately, it’s a fact of raising cattle that some animals will become injured to the extent that they are unable to stand or walk without assistance.

Two grazing trials were conducted to determine i/protein or energy was first limiting in the spring-and fall-born nursing calf grazing native sandhills range. Spring-born calves supplemented with escape protein gained more rapidly than calves supplemented with energy or nonsupplemented controls. Fall-born calves supplemented with escape protein gained more rapidly than those supplemented with rumen degradable protein or energy and nonsupplemented controls early in the trial, but gained at a similar rate to the energy controls by the end of the trial. Milk intake was similar across treatments for both trials. Escape protein is more limiting in the young nursing calf …

Economic efficiency of beef production to weaning and to slaughter was estimated in three groups, different in milk available (low, medium, and high) to the calves but the same in growth potential. Efficiency was the ratio of income to expenses. Income was derived from cull cows and calves at weaning or carcasses of calves fed to slaughter. Feed and non-feed expenses for the cowherd and for calves to weaning or to slaughter were included. Efficiencies were estimated assuming observed reproductive rates and energy requirements for maintenance, as well as for equal reproductive rates and equal requirements for maintenance in the …

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 …

Production From Heifers And First Calvers, G J. Sawyer

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

Heifers and first calvers present the major problems of the beef breeding herd. Reproduction rates, calf growth and survival of first calvers are generally much poorer than those of adult breeders.

Early successful reproductive performance is important in beef herds because of the high overhead cost of keeping breeding beef heifers or cows, Where possible, beef producers should aim to join heifers at 14 to 15 months of age. To achieve this goal, producers should set production targets for those animals. These targets will differ from farm to farm depending on when calves are turned off and the seasonal feed …

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.

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'

There are four major regions of beef production in Western Australia, each suited to its own type of husbandry. In such a large area, climate plays an important part in limiting production off pasture and this is reflected in the different patterns of production that have emerged from the accumulated experience of working in these areas.

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.
