Digestible And Metabolizable Energy In Ground Yellow Corn, Rice Bran, And Copra Meal Fed To 10 To 15 Kg Philippine Native Pigs (Benguet Strain), Mary Arnel D. Garcia

The Philippine Agricultural Scientist

The experiment was conducted to determine the digestible energy (DE), metabolizable energy (ME), and apparent total tract digestibility (ATTD) of gross energy in ground yellow corn, rice bran, and copra meal when fed to Philippine native pigs. Nine barrows with an average initial bodyweight of 10 kg and ages ranging from 60 to 75 d old were housed individually in metabolism crates and randomly allotted to a triplicated incomplete 3 × 2 Latin square design with three diets and two periods. A corn-based diet containing 94.89% yellow corn and two diets containing 66.42% yellow corn and 30% rice bran or …

A Decision Tool To Identify Population Management Strategies For Common Ravens And Other Avian Predators, Andrea F. Currylow, Brenda J. Hanley, Kerry L. Holcomb, Timothy Shields, Stephen Boland, William I. Boarman, Mercy Vaughn

Human–Wildlife Interactions

Some avian species have developed the capacity to leverage resource subsidies associated with human manipulated landscapes to increase population densities in habitats with naturally low carrying capacities. Elevated corvid densities and new territory establishment have led to an unsustainable increase in depredation pressure on sympatric native wildlife prey populations as well as in crop damage. Yet, subsidized predator removal programs aimed at reducing densities are likely most effective longer-term when conducted in tandem with subsidy control, habitat management, and robust assessment monitoring programs. We developed decision support software that leverages stage structured Lefkovitch population matrices to compare and identify treatment …

Genetic Polymorphisms Of The Glucocorticoid Receptor And Interleulin-8 Receptor Genes And Their Relationship To Production Traits And Hair Coat Scores In Crossbred Cattle, Avery B. Deaton, Laura Meyer, Jeremy Powell, Charles F. Rosenkrans Jr.

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

Little is understood about how the diversity of genes, specifically the glucocorticoid receptor (GR) and interleukin-8 receptor (CXCR2), are related to reproductive health and how this affects physical traits in cattle. Glucocorticoid receptors have been positively associated with higher milk yields, lactose content, feed intake, and feed conversion rates. Interleukin-8 genes are part of the innate immune response and help with many aspects of female reproductive health, such as protecting the embryo from the maternal immune system during pregnancy. The objective of this research was to identify polymorphisms in the GR and CXCR2 genes and to associate genotypes between the …

How Rabbit Poisoning Methods Work, S H. Wheeler

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

While the "rabbit plauges" of the past are a distant memory for most farmers, rabbit numbers must still be controlled in many parts of Western Australia. Rabit control techniques rely heavily on poisoning, which given the right conditions can kill a high percentage of rabbits at risk.

Recent research by the Agricultural Protection Board has been aimed at determining how different poisons, baits and poisoning methods work. By knowing in detail how each method works and what influences its results, we can choose the best control method for a particular place and time, avoid costly failures, and increase the effectiveness …

Feral Donkeys : An Assessment Of Control In The Kimberley, S H. Wheeler

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

Feral donkeys are one of the major limitations to increased pastoral production in many parts of the Kimberley area of Western Australia, where they compete with cattle for food. In addition donkeys are aggressive animals, driving cattle from watering points and better grazing areas. They eliminate perenial plants by overgrazing and therefore reduce the carrying capacity of the range.

Originally introduced as draught animals, donkeys were released when cars arrived; since then they have bred up to large numbers in many areas.

For several years the Agricultural Protection Board has undertaken a programme of donkey shooting from helicopters. Since this …

Breeding And Use Of Nonhuman Primates In The Usa, Joe R. Held

International Journal for the Study of Animal Problems

Several species of nonhuman primates, each possessing specific characteristics of particular value, are used by the United States biomedical community in various health-related activities. These animals are man's closest relatives and are indispensable in understanding and controlling human health problems. The destruction of primate habitats and embargoes on the export of primates from source countries have decreased the supply of these animals. The inadequate and erratic supply of these resources threatens the continuation of many ongoing and new activities contributing to improving human health. In the U.S., a program has been developed to meet the health needs of primates:

The Medina Pig Research Station, Department Of Agriculture, Western Australia

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

Before the Department of Agriculture's Medina Pig Research Station was established in 1964, pig production research had been carried out on Denmark Research Station, Muresk Agricultural College and in some commercial herds.

However, with increasing specialisation in the pig industry better facilities were needed. Medina Research Station provides such facilities, allowing it to carry out research to provide detailed information of immediate practical value for both extensive and intensive pig production enterprises.

Super Spreader Distributes Snail Baits, G D. Rimes, W. M. O'Donnell

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

THE problem of distributing snail bait on broad acres has been overcome by simple modifications to a conventional super spreader.

Pig Husbandry Research In Western Australia, N W. Godfrey

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

IN the past it has not been possible to undertake research work with pigs on any appreciable scale in Western Australia.

A small herd has been maintained at Denmark Research Station for some years as a demonstration side-line unit, run in conjunction with the dairy herd.

A number of very useful trials have been carried out with the Denmark herd, but its size has limited the comprehensiveness of the type of research work that could be undertaken.

Poisoning Rabbits From The Air, C D. Gooding

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

AERIAL baiting gives spectacular kills of rabbits in country which cannot be effectively treated by conventional means, and has been widely adopted in New Zealand and other States in Australia.

Here Mr. Gooding reports on developments in aerial baiting in Victoria, and suggests practical applications in Western Australia.

The Success Of The Rabbit 'Killer' Trials, A R. Tomlinson

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

SUCCESS well beyond what was anticipated has been achieved in a two year trial of a modified version of the rabbit "killer" method.

In the "killer" method, trained officers are employed to kill rabbits instead of to inspect and supervise the activities of farmers and, in fact, these officers do all the actual work of destruction.

This system was advocated by the W.A. Royal Commission which reported on Vermin Control in this State in 1944, and it was used successfully in New Zealand.

These trials were applied only to poisoning and not to overall destruction measures. The main object was …

Vermin Control In W.A, A R. Tomlinson

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

THE annual report of the Agriculture Protection Board of W.A. for 1958-1959 indicated that while vermin control had continued at a relatively high standard throughout the State, most of the animal and bird pests were at the lowest level within the memory of most people.

However, there were ample warnings that any relaxation in control work could have rapid and serious consequences.

Free Feeding For The Control Of Rabbits, C Marshall

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

IN common with most other farm work, the control of rabbits calls for a high degree of skill, patience and perseverance.

There is no short cut to success, and if results are required we must be prepared to give of our best.

Failures of control works are experienced at various times, and the reasons can generally be traced back to something we have failed to do or some short cut we have tried to take.

However, we should not lose heart from one failure. During normal farming procedure, if a farmer's crop fails he does not give up planting in …
