The Impact Of Heat Stress, Nutritional Restrictions, And The Effect On The Growth And Reproductive Performance Of Malpura Rams

Marsupials living in Australia’s hot arid environment must deal with exposure to extreme conditions such as high temperatures, solar radiation and limited food and water supply. More than 50% of the world’s marsupial species occur only in Australia (Steffen et al 2009), which indicates their ability to adapt to Australian

When it comes to feeding show cattle many raisers have certain feeding strategies that they follow, ensuring they can maintain their goal on winning. Along with feeding it takes exercise so that one’s show calf will not become stout nor stubborn. Certain aspects are necessary to show an animal

The Animal Science discourse community is community that dedicates their studies in having an immense knowledge on animal health, animal behavior, farm management, and livestock production. For the reason that people keep animals in captivity for recreational, educational, experimental, production or breeding, people within the animal science discourse community believe it is important come to understand the well-being of the animals we depend on. The common goal within the people in this field is to get involved in the care of animals. In order to achieve this, individuals within the field put major emphasis on the data collected from their research, which they expect to share with other individuals such as people within the field and the outer world.

According to Ohio State University, Brangus cows originated from Brahman and Angus cattle. Brangus cattle come in different colors such as red and black. The Brangus breed is actually a very muscular breed. Brangus have ears that are similar to Brahman, a little droopy. They have an appealing look, they have a smaller hump-like figure on their backs similar to a Brahman. Brangus cows can be a mix of one to three-quarters brahman, the rest Angus.

There is little evidence of how horses were managed within the first years of domestication (Dierendonc). However, in most horse husbandry systems today horses are kept confined and solitary with very little social contact. This can be seen as optimal to ensure physical health, to prevent injury or to allow exact individual monitoring (Dierendonc, 2006). However, these systems often ignore the basic needs of the horse, e.g. social contact, foraging and locomotion needs, often resulting in abnormal behaviours. The start of stereotypic behaviour usually is related to chronic stress due to mal-adaptations to cope with the environment (Hausberger et al., 2009).

The main idea of Road salt can change sex ratios in frog populations was that road salt put down on roads to melt snow, can impact the sex ratios of frogs. The researchers found that the proportions of female in tadpoles were reduced down 10 percent when exposed to road salts. This suggest that road salt may have a masculinizing effect of frogs. For the experiment researchers used a 500 litter tank containing various levels of road salt to leaf litters from maple and oak trees. The scientist observed the sex ratio for the oak leaf litter without salt was female-biased 63 percent. But, when the salt was added the female portion of frogs decrease by 10 percent. The scientist also noticed that the oak leaf litter female tadpoles were larger

This study design is an observational study. The research was carried out using examination and analysis of disease models and special and temporal scales between the species involved. In this study, Lyme incidents are the dependent variable and the animal abundance being looked at it the independent variable. Species were placed into groups and parameters were set up in order to facilitate examination. Lyme disease rates and information were taken from county records. Once the data was collected, mathematical formulas were used for further analysis and to get results. During the study, some proxy variables had to be used. One of these was using buck harvest to account for deer density. This was done in Virginia. This type of proxy weakens the arguments made in this study because it is only accounting for male deer and also, the number of buck harvest may not necessarily be equivalent to the entire density of deer, including those

Black more and Delaney explained mechanical stunning of animals. According to them it is achieved by using Penetrative Captive Bolt or Non-penetrative Percussion Stunning. Neuronal dysfunction and/or destruction, and subsequent insensibility result due to transference of kinetic energy from a moving object to the brain so, the basic principles are the same. Initial observations found that mechanical stunning is humane, except in very large bulls, provided the captive bolt penetrates the skull of the animal at the correct site. The correct site in hornless sheep is at the highest point of the head when held horizontally and aimed towards the throat; for horned sheep, the site is just behind the ridge that runs between the horns and aimed towards

Extreme Weather – The weather can affect beef cattle during all stages of life. When extreme heat of extreme cold set in, animals will experience different reactions. In hot weather, there may be a decrease in appetite due to the heat. On the opposite end, there will be an increased desire for food in cold weather to

To start off, the passalidae is comparable to many other beetles in terms of strength. For example, the dung beetle is the world’s strongest animal according to Dr. Keen (Daily Mail). This beetle can pull six filled double decker busses in proportion to humans, equivalent to 1,141 times their body weight. What might cause the beetle to have such strength? Researches say that this beetle’s sex life is to be responsible (University of London). Because of fierce rivalry, competing with other males for who gets to mate with the females, the beetle has developed strength over time and this may result in the beetle’s incredible strength. To compare, the betsy bug (horned passalus beetle) in particular can lift near a hundred times the bug’s own body

Animal science is a very broad topic. Form General Animal Science class I have learned that animal science is concerned with the science and also with the business to produce livestock such as cattle, horses, sheep, swine and poultry. In this course I have also learned that the scientists apply various genetic modifications on animal to increase production and management of livestock. To supply for the demand of animal in worldwide the industries of livestock are responsible for maintaining the well-being of the animals. The three concepts that I learned after taking this class are choosing the right breed of animal is necessary for mass production, genetic selection, and food safety.

This breed consists of Charolais, Maine-Anjou, Limousin, Simmental, and Chinana. These animals are the largest in statute compared to the American and British Breeds. Comparing to the British Breeds, the European Breeds are larger in-built and reach maturity later in life. This breed’s carcass tends to have less fat and high saleable meat cut products at market, but with a lower grade of meat. Also, this breed is known to have high fertility problems, larger birthing weights, and difficult calving. The exhibitor may experience a more difficult time training this breed because of the high-headed

Tracey Koester of Beef Magazine did an excellent job writing the article titled, "Is your herd health protocol as good as everyone elses?" This article explains a study done by the Red Angus Association of America and Kansas State University. This study interviewed cow-calf veterinarians about herd health practices.

Inbreeding depression occurs when species inbreed to a point where the overall fitness of the species decreases significantly. Slate and Pemberton studied how reduced heterozygosity affected the sperm and gonads of wild rabbits (Oryctolagus cuniculus) across the United Kingdom; they considered 112 individuals as well as populations (2006). The study found an important relationship: with a reduced heterozygosity, the production of normal sperm was also reduced (Slate and Pemberton, 2006). It is important to note; the relationship’s effect was found amongst individuals not entire populations (Slate and Pemberton, 2006). To compile this data, the scientists measured degrees of inbreeding with a molecular measure, using 29 microsatellite loci for each individual male rabbit (Slate and Pemberton, 2006). This loci region is known to have a relationship with the genes coding for inbreeding depression, although why is not completely understood (Slate and Pemberton, 2006).

Argali sheep, or the Ovis ammon, are calm, social, non-aggressive animals that are related to the common domestic sheep. They inhabit the mountainous areas of Central and Southern Asia and have a lifespan of 10-13 years. Argali are approximately the same length as the domestic sheep but are much taller and heavier, as their weight ranges from 65-180 kilograms, their shoulder height from 90-120 centimeters, and their length from 120-200 centimeters. The coats of these sheep are light yellow to a darker grey-brown in color, and they have lighter faces, abdomens, and inner legs. Ewes have grey hooves while rams have black hooves. Argali (rams) are also the fastest sheep, as they can run for up to an hour straight at 50 kilometers per hour with their long, thin legs and compact bodies. Known for their famous horns, a ram’s corkscrew horn can be up to 13 percent of the males’ body mass and are usually the prized possession of hunters. While a ram’s horns can reach over 150 centimeters, female argali ewes are only 60% to 70% the size of rams, and their horns rarely reach over 50 centimeter in length.
