Battery Eggs Sale and Production in the ACT

On 31 July 1998 the Commission received a request from the Treasurer to undertake, on behalf of the Government of the Australian Capital Territory, a study into whether it is in the public interest for the ACT to: * ban the sale of eggs from battery caged hens in the ACT (whether produced in the ACT or not); * ban the production of eggs from battery caged hens in the ACT; and * introduce a labelling requirement for all eggs displayed, or sold, in the ACT to indicate the conditions under which the hens produced the eggs.

Regulating the market for human eggs.

This essay provides a rationale for a regulated market for human oocytes. Although the commodification of human oocytes raises important moral concerns, these concerns do not justify laws banning commerce in human eggs. Given the burgeoning ART industry and the growing oocyte market, the most prudent course of action is to develop regulations for the human oocyte market that are designed to protect and promote important social values, such as health, safety, liberty, and respect for human life. Other responses, such as banning the sale of eggs altogether or allowing donors to be compensated only for their services, would either create a black market or would lead to corruption and abuse. Society still needs to debate specific rules and policies that should govern the human egg market, but further discussion of that important task is best left to legislative bodies and other commentators.

Broodstock replacement policies for rainbow trout under photoperiod control and uncertainty

The economics of broodstock replacement for rainbow trout under production conditions of photoperiod control and uncertainty is analyzed by stochastic simulation using a systems model to represent the nature of egg production as the broodstock matures. Probability distributions for number, size and quality of eggs produced as well as growth and mortality of the fish are incorporated into the systems model. These distributions are conditioned on the age of the fish. Management policies of retaining broodstock for one through four spawns are evaluated in terms of net contribution to the firm's profit. Revenues are received from sale of eggs and broodstock, while variable costs are incurred for labor, feed and replacement fish. The data, obtained from a commercial egg-producing firm, reflect increased numbers and size of eggs as the fish grow as well as reduced feed efficiency and higher mortality with age. Given a 10-month spawning cycle, induced by photoperiod control, a two-spawn policy offers the greatest expected net contribution to net income followed by three-, one- and four-spawn policies.

Les politiques de l'élevage au Canada et leurs effets géo-économiques

In Canada, the marketing of the products of cattle-breeding is done in several different ways. Whereas the cattle market enjoys a large amount of freedom, the sales of milk, eggs, poultry and pork are controlled by the marketing boards. Their powers, however, vary considerably. As regards milk and poultry farming planning is very strict and production is adjusted to consumption. The quotas allotted to each province do not allow great geographical changes in the areas of production and their boundaries remain permanent.

EFFECTS OF AGE AT PHOTOPERIOD CHANGE AND DIETARY PROTEIN ON PERFORMANCES OF FOUR DWARF MATERNAL MEAT PARENT GENOTYPES AND THEIR BROILER CHICKEN PROGENY

A factorial experiment was conducted with 3030 chickens of four maternal dwarf genotypes mated with normal males to estimate the effects of age at a photoperiod change from 8 to 12 h (daily) at 140 or 154 days, and two levels of dietary protein (15 or 17%) on general performance, incidence of Fatty Liver Syndrome and monetary returns. Three of the four maternal genotypes performed similarly for most traits measured but one genotype exhibited better feed efficency of egg production, produced more eggs and, although the eggs were smaller resulted in the highest monetary returns. Delaying the increase in photoperiod change retarded sexual maturity and reduced egg weight at 203 days and egg specific gravity at 406 days. The 17% protein diet improved egg production (including hatching eggs), feed efficiency of egg production, egg weights; and female body weights at 154 and 446 days of age were also heavier. Dietary protein levels had no effect on mortality (P > 0.05). Mean monetary returns from the sale of table eggs, hatching eggs and salvage meat in excess of the costs of day-old breeder stock and feed, averaged $1.07 more per bird fed the 17% diet. The progeny test revealed significant differences among genotypes for male mortality, male and female body weights, and feed conversion; however, monetary returns over feed and chick cost were similar. The time of change in photoperiod and dietary treatments had no significant effect on the overall performance of broiler progeny but there was a genotype × parental diet interaction for 43 day female body weights.

Retail Sales of Eggs Priced by the Dozen and Pound—A Controlled Experiment

In a matched-lot controlled experiment, eggs priced by the pound outsold those priced by the dozen. Consumers were given the choice of buying eggs priced by the dozen or by the pound; the egg lots were displayed side by side on a shelf. Each dozen carton sold by the pound had a label showing net weight in pounds (to two decimal places), selling price per pound, and total price per dozen. An electronic scale was used for weighing, pricing, and labeling. Eggs were priced at 46 cents a pound, comparable to 25.5 ounce-per-dozen large eggs selling for 73 cents a dozen. Medium eggs were 68 cents, and small eggs 55 cents a dozen. Results were based on a one-month test (October, 1974) in which 19,562 dozen cartons of eggs were purchased. The test market was the Main Commissary, a large supermarket, at Fort Riley, Kansas. Sixty-three percent of the consumers buying eggs during the test purchased eggs priced by the pound.

The Economics of Egg Production

Poultry raising on scientific and commercial lines is relatively new to Pakistan, indeed, to this whole of the Sub-continent. In undivided India village farmers used to keep some fowls which were produced on primitive methods of natural hatching under the broody hen and reared on garbage dumps, left¬over meals, and mixed grain, which involved almost no financial investment. No special care was taken to prepare poultry feed or arrange for poultry health and hygiene. The basic idea of such part-time farming was to augment one's income from the sale of eggs and birds. This part-time farming still accounts for about 85 percent; of Pakistan's total egg production.1 To match the tremendous rise in demand for meat growth in poultry farming will have to take place on more modern and capital-intensive chicken farms. Such enterprises are the subject of this study.

Comparative Returns From Sales of Graded and Breaker Eggs

Total returns and prices received by a commercial egg producer in northeastern Kansas from eggs sold on a graded basis or as breaker eggs (either on a liquid-yield or a minimum-gross-weight-per-case basis) were compared in relation to the market price situation, season of year, age of layers, and time (March or September) pullets began laying. Cage layers were housed when 20 weeks old and heid for a 65-week laying period. Returns and prices were those of six different market price periods, 1965–66 through 1970–71.Selling eggs on a graded basis resulted in significantly higher gross returns in each price period than did selling them as breaker eggs. Breaker eggs sold on a liquid-yield basis brought higher returns than did those sold on the traditional, minimum-gross-weight-per-case basis. Gross returns for layers beginning to lay in March or September, with eggs sold either as graded or breaker eggs, did not differ significantly.

The Selection and Management of Turkey Breeders

THE principal financial return from a flock of turkeys is from the sale of the carcasses rather than the sale of market eggs. As a result the basis of selection of turkey breeders has been different from the methods employed with chickens. In the past the selection has been based almost entirely upon trueness to standard type and color as described by the American Standard of Perfection or else trueness to the market type preferred by the breeder.Both trueness to standard and to an ideal market type are important but will not be discussed in this paper. However, in addition to the above mentioned considerations, the successful turkey breeder should consider those factors which will give him poults at the lowest possible cost. In the final analysis the most ideal turkey breeder is that bird which will produce the largest number of healthy, vigorous poults bred to develop the .
