Induced Molting of Layer Birds Essay

Never being able to stretch their wings or walk around again. Standing on wire floors which lead to serious health issues. Dropping there faeces to a tray below them which would rarely get cleaned. Until around 2 years later when they stop laying. No, they are not let out into open fields for the next 10 years of their life that they are capable to live. Instead, they are trucked to slaughterhouses. Many birds die within these 2 years, and survivors are often forced to live with their dead and dying cage mates. Hens can suffer in pain and agony caused by these appalling conditions, caged eggs should be completely

The business plan with such high gross margin seems quite favorable. However, the company’s concept has some potential problems. The company did not mention how to minimize the risk of hurting women’s health when they proceeded to collect their eggs. Furthermore, the business plan did not include the best use time of the storage eggs. If the eggs were expected to keep in years, the quality of eggs could not be ensured. Finally, they did not offer a strong report to state the potential issues of using freezing eggs. Would the technique influence the health of babies?

The primary purpose of the lab was to test and observe the effects of the process of osmosis on decalcified eggs. Before the process, the initial weights of the eggs were taken and noted. Two eggs were then immersed in a deionized water solution. The same was repeated to the other two solutions of 20% and 40% sucrose. The weights of the eggs were measured after 15 minutes to note the change in mass due to osmosis and again after 60 minutes to take the final measurement. Overall, while some human error might arise in the weighing process, care was taken in handling the eggs and during the weighing process. As such, it was found that the eggs behaved as predicted. It was found that the eggs placed in the hypertonic solution lost

The production of eggs through battery hens should be banned as conditions in factory farms inflict pain and stress on the animals. The lifestyle that 12 million hens in Australia are forced and trapped into is merely inhumane and unjust. Factory farms confine these birds into cages, often containing up to two or three other hens. , which allow them a space of approximately the size of an A4 sheet of paper. In these conditions, there merely isn't enough space for a hen to function independently and rightfully. They are compelled to eat, sleep and defecate in this small space – standing on a wire mesh floor day and night. Hens in cages suffer intensely and continuously throughout their lives as they are unable to stretch, flap their wings,

Ontario egg producers is less than the minimum efficient size while the average flock size in the

The purpose to this experiment was to study the effect of osmosis in de-shelled chicken eggs in different percentages of sucrose solutions. Osmosis is the process, in which, water moves across a differentially permeable membrane. The eggs were soaked in vinegar to remove the outside hard shell but still leave the egg in its membrane. By placing the six de-shelled in different sucrose solutions, we tested the rate of osmosis. The eggs were placed in the solutions for an hour and weighed in fifteen minute intervals. Then, each weight was recorded and graphed. The results showed that the egg in the water solution gained the most weigh and the only other egg that gained a little weight was the one in the 10% solution. All the other eggs in the different solutions lost weight, even the unknown solution. According to the results the egg that was in the distilled water solution gained weight because it is the hypertonic solution. All the other eggs lost weight because they were placed in hypotonic solutions with different concentrations of sucrose. The egg that was placed in the higher concentration of sucrose lost the most weight. So, the higher the concentration of sucrose, the more water the egg lost.

The Hawaiian Duck is blessed with one of the best habitats in the world. It resides in the beautiful islands and the epitome of all beautiful islands known as Hawaii. They are mostly found in lowland wetlands, river valleys, and mountain streams. This works to this bird’s advantages. They mostly try to stay away from the more urban parts of Hawaii and stick to their usual wetland setting. However, there not much of these habitats around on the virtually miniature island of Hawaii, which makes this bird’s effort of trying to stick around, just that much harder. Its endangerment has a large part to do with the fact that you cannot find all of these elements in many places on the island of Hawaii. The Hawaiian duck’s habitat is a huge part of what this bird is and how it functions through its

Chickens used for egg production typically live in one of many battery cages crammed into a long windowless shed. Ten or more of these hens are packed together in a cage that is about the size of a drawer in a filing cabinet. This causes frustration and fighting between the hens. To keep this from happening, farmers often cut or burn part of their beaks off without medicine to dull the pain. Hens who become sick are usually not given proper veterinary care and are left to die slowly and painfully. Some of the eggs laid by the hens are hatched by another industry to supply more chickens for egg production. Since the hatched male chicks cannot lay eggs, they are often killed by grinding or suffocation. When the hens grow old and stop producing as many eggs, many farmers will deny them proper nutrition to try and “shock” their bodies into laying eggs one last time. Then they are slaughtered and their bodies are used for food scraps.

An egg has a semi-permeable membrane, thus processes like osmosis could occur. Osmosis is the movement of water molecules from an area of higher water concentration to an area of a lower water concentration. Osmosis is important, especially for living organisms, as they help distribute nutrients in the body. An egg’s mass would change when it is soaked in different substances. The goal of this experiment was to investigate how an egg changes through osmosis. This experiment was done to show how substances affect the mass of an egg. To start off, an egg’s mass was measured by putting the egg in a beaker then placing it on a mass scale. The beaker was then filled with vinegar and left alone for twenty-four hours. After a day, the egg was taken

Layers practically spent their youth to maturity confined in cages no bigger than their bodies. The cages are densely packed next and on top of one another. Laying hens are frequently starved to maximize their eggs production. The goal is to maximize production with amount of effort. The way I see it: It is like life in prison for those hens. They cannot move and even flap their wings. Living in overcrowded area, it is a natural tendency for the birds to peck at each other. To solve that problem, new born chicks will get part of their top beaks cut off without any painkillers. Many chicks experience pain and unable eat for days. When hens can no longer produce eggs, they are killed and sent elsewhere. Why would one kill those hens? Can we still use them for

This is the final step of the experiment. The shell-less egg was now placed into a new cup, but very carefully, as the egg was more fragile than when it was soaked in vinegar. The egg in the new cup was then covered with water. The egg sat in the water for a 24 hour time period once again. During this 24 hour time period the eggs appearance and size were once again recorded. After the time period had completed, the egg was removed from the water and was very carefully patted dry. Since the egg was now swollen, extra care was needed when holding the egg. The swollen egg was placed on the scale on last time and its mass was recorded as M3.

Severely restricted inside the barren cages, the birds are unable to engage in nearly any of their natural habits, including nesting, perching, walking, dust bathing, foraging, or even spreading their wings” (HSUS, 2009).

When the 4 eggs were weighed it was found that out of the 4 solutions, 2 were hypotonic and 2 were hypertonic. The mass of 2 of the eggs increased and the other 2 decreased after 60 minutes in the various solutions. Out of the 4, the most hypotonic solution was the distilled water; and the most hypertonic solution was the solution with 2.0M glucose. The

The eggs will increase and decrease in mass when placed solutions with different amount of solutes. This

4.14. The accuracy of the data is dependent on the correct controls being in place, Ensuring temperate stays the same throughout all solutions, making sure that the solutions are correct that the weight and size of the eggs are the measured correctly and that when the eggs are removed they are removed at the same time. Some of the eggs were not completely submerged in the solution this may cause some errors in the experiment and may have caused varying results. The eggs were of different sizes this also will cause the results to vary, Gathering eggs of exact size and weight would have ensured the results were correct. The eggs may not have been dried enough also causing results to vary; this can be fixed by ensuring that the eggs are thoroughly dried. The eggs were taken out at a time around about 24 hours, having an exact time to remove the eggs would have eliminated errors.
