Nitrogen Cycle steps

It is one of the most important cycles as it represent the majority of elements in the atmosphere. Nitrogen is used by living organisms to produce organic molecules like amino acids, proteins or nucleic acids. plants receive nitrogen from soil as an inorganic nitrate. animals receive the required amount of nitrogen they need for metabolism, growth and reproduction consuming living or dead organisms containing the composed nitrogen molecules. Nitrogen is being then implemented into soil from where it is being carried out by different bacteria and other organisms and reintroduced into the atmosphere.

Describe the estrus cycle.

The estrous cycle can be divided into four stages: proestrus, estrus, metestrus, and diestrus. During proestrus the CL regresses (progesterone declines) and a preovulatory follicle undergoes its final growth phase (estradiol increases). Ovulation usually occurs during estrus (cows ovulate during metestrus). Proestrus and estrus comprise the follicular phase. Corpora lutea develop during metestrus and function at optimum during diestrus. Metestrus and diestrus make up the luteal phase.

Biomagnification

What is the difference between ruminant and non ruminant animals?

The main difference between ruminant and non-ruminant animals is that ruminant animals are herbivores whereas non-ruminant animals are omnivores or carnivores. Thus, ruminant animals have a complex rumen to digest plant material while non-ruminant animals have a simple stomach since their food is easy to digest.

abiotic factors

The non-living parts of an organism's habitat.

phosphorus cycle steps

The phosphorus cycle is the biogeochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere. Initially, phosphate weathers from rocks. The small losses caused by leaching through the action of rain are balanced in the gains from weathering rocks. In soil, phosphate is absorbed on clay surfaces and organic matter particles and becomes incorporated (immobilized). Plants dissolve ionized forms of phosphate. Herbivores obtain phosphorus by eating plants, and carnivores by eating herbivores. Herbivores and carnivores excrete phosphorus as a waste product in urine and feces. Phosphorus is released back to the soil when plants or animal matter decomposes and the cycle repeats.

How do vaccines work?

The vaccine inserts dead or weakened pathogen to produce a primary immune response. This stimulated immune system with 'remember' the response should a real disease threat occur in the future.

water cycle steps

The water cycle is the only way that Earth can be continually supplied with fresh water. The heat from the sun is the most important part of renewing our water supply. This heat soaks up water from the oceans, lakes, rivers, trees and plants in process called evaporation. As the water mixes with the air it forms water vapor. As the air cools, the water vapor forms clouds. This is called condensation. Most of the water is immediately returned to the seas by rain (precipitation). The rest of the water vapor is carried inside clouds by wind over land where it rains or snows. Rain and melted snow is brought back to the oceans by rivers, streams, and run-off from glaciers and water underground.

Sulphur Cycle Steps

When sulphur is released from the rock and comes in contact with air, it is converted into sulfate (SO4), which is taken up by plants and microorganisms and converted into organic forms. Animals acquire these organic forms of sulfur from their foods. When organisms die and decompose, some of the sulfur enters the tissues of microorganisms and some is released again as sulfate. Additional sulphur enters the ocean through fallout from the atmosphere. Once in the ocean, some of the sulphur cycles through marine communities as it moves through food chains, some reenters the atmosphere, and some is lost to the ocean depths as it combines with iron to form ferrous sulfide (FeS). Sulphur reenters the atmosphere naturally in three major ways: sea spray releases large amounts of the element from the ocean into the atmosphere; anaerobic respiration by sulfate-reducing bacteria causes the release of hydrogen sulfide (H2S) gas especially from marshes, tidal flats, and similar environments in which anaerobic microorganisms thrive; and volcanic activity releases additional but much smaller amounts of sulfur gas into the atmosphere.

Animal handling techniques

-Animals should be approached in a calm and confident manner, avoiding exaggerated or sudden movements, such as waving of the hands and arms -Using soft tones and a quiet voice when talking to animals may help alert them to a non-threatening approach and reinforce a caring attitude in the handler -Choose an appropriate handling method using sufficient force to immobilize the animal but not hinder breathing or cause bruising. -Observe the animals response after handling. If animal shies away or hides, it could have been too much force. An animal with a positive handling experience often will voluntarily return to the handler. Remain still for a moment and observe the animal for signs of fear or injury. -Skill should be sufficient to capture animals quickly, confidently and securely on first approach without any chasing. Failed attempts to catch an animal can increase its anxiety and lead to further evasive response, resulting in frustration and sometimes impatience in the handler -Attempt to gain voluntary cooperation of animals using positive reinforcement (i.e. treats) for procedures that would normally need restraint

Monogastric digestive system

-Chewed food mixes with saliva, goes down the esophagus into the stomach. -motility of the stomach mixes the digesta with the gastric juices and to move the digesta into the small intestine. -The small intestine (duodenum, jejunum and the ileum) is the site where the majority of digestion takes place and most, if not all, nutrient absorption occurs. -The duodenum is the site for the mixing of digesta with intestinal, liver and pancreatic secretions to buffer the contents as they leave the stomach, and to lubricate the bolus for ease of movement through the intestines. -The caecum and colon (hind gut) retrieve any nutrients, primarily water and electrolytes, remaining in the digesta as it leaves the small intestine. The caecum is a blind sac arising at the junction of the ileum and colon. -Anaerobic fermentation of fiber in the caecum and colon produces some utilizable energy in the form of volatile fatty acids. -The amount of energy produced is small in relation to the pig's total requirement but hind gut fermentation liberates substantial nutrients in horses and rabbits.

Heat Detection

-In most natural mating situations, the male is the best possible detector. In artificial breeding or hand mating, the need to pick cows that are in heat is of paramount importance. Techniques include use of infertile teasers combined with heat mount detectors, tail paint, or chin ball or sire-sine marking harnesses. In dairy herds it is usual practice to dispense with the teasers and depend on other cows to pick out and mount the cows that are in heat. -looking for the changes in animal behavior that are associated with a female standing to be mounted by a male or another female.

Criteria for Culling animals

-Low fertility:In females this may be based on pregnancy testing or wet/dry status at mustering.In males this is usually based on combined examination of the teeth, feet and testicles a few months prior to joining. Bulls may also undergo a Veterinary Bull Breeding Soundness Evaluation. -Ability to deliver a calf or lamb or kid unassisted. -Ability to rear a calf or lamb or kid to weaning. -Age - often the best way to do this is based on the animal's teeth (animals with worn teeth or broken mouth usually do poorly). -Temperament. -Physical problems, including udder, foot and other structural problems such as excessive breech wrinkle/cover in Merinos. -Production targets, including performance of offspring (there is no point in keeping animals that fail to produce themselves or that produce low value offspring). -Disease susceptibility.

Nonruminant Herbivore Digestion

-horse, rabbit and guinea pig -combines features of both the ruminant and monogastric systems. -digestion of non-structural carbohydrates such as starch, proteins, minerals and vitamins takes place in the stomach and small intestine. -The more fibrous part of the feed, which in some situations is the majority of the diet, is passed through the small intestine to the hindgut (caecum and colon) where it undergoes bacterial fermentation. -since hind-gut fermentation is distal to the small intestine the non-ruminant herbivore may not be as efficient in using fibrous foodstuffs as is the ruminant. -There is absorption from the hind-gut of by-products of bacterial fermentation such as volatile fatty acids, free amino acids, B-vitamins and minerals released from plant sources, but losses of these nutrients in the feces is greater in the horse than in the cow.

Basic handling procedures for animal vaccines

-purchase from a reputable source who will deliver a high quality vaccine -store in a refrigerator: Heat can make the vaccines ineffective, so they should not be allowed to warm up to room temperature at any time. Do not allow to freeze -use only the rehydrating solution packaged with the vaccine if it needs to be reconstituted. -Determine how many animals you need to vaccinate and only mix enough to vaccinate that number. Any leftover vaccine should be thrown away as it loses its effectiveness during storage (as little as 2 hours) -only mix what you will use in a very short period of time -Follow label directions for how to give the injection

Using a Pearson's square with supplement mixes

1) Grain mix A is 40% corn and 60% soybean hulls (SBH), whereas grain mix B is 50% dried distillers grains (DDG) and 50% cottonseed hulls (CSH). The energy requirement being balanced for is 1.44 Mcal/d. (Energy Concentrations as follows: Corn 2.01 Soybean hulls 1.37 Dried distillers grains 1.97 Cottonseed hulls 0.48) 2)First, treat grain mixes A and B as the two feeds to use in the Pearson's Square. This means you must calculate the amount of energy (Mcal/kg) available in each mix. These are the steps: --1. Grain mix A a. 40% corn at 2.01 Mcal/kg, so 2.01 * (40 ÷ 100) = 0.80 Mcal/kg b. 60% SBH at 1.37 Mcal/kg, so 1.37 * (60 ÷ 100) = 0.82 Mcal/kg c. 0.80 + 0.82 = 1.62 Mcal/kg --2. Grain mix B a. 50% DDG at 1.97 Mcal/kg, so 1.97 * (50 ÷ 100) = 0.98 b. 50% CSH at 0.48 Mcal/kg, so 0.48 * (50 ÷ 100) = 0.24 c. 0.98 + 0.24 = 1.22 Mcal/kg 3) make sure the energy requirement (1.44 Mcal/d) falls within the range of the energy content of each grain mix (1.22 to 1.62 Mcal/kg); otherwise, the Pearson's Square method will not work. 4) Pearson's Square calculations: ----1. Subtract across the diagonal: a. 1.44 - 1.22 = 0.22 parts grain mix A b. 1.44 - 1.62 = 0.18 parts grain mix B ----2. Sum the parts: a. 0.22 parts grain mix A + 0.18 parts grain mix B = 0.40 total parts ----3. Divide each part by the total to calculate the percent of each feed to include. This step varies from the first example, because more than two ingredients are being used. Before dividing, multiply the parts of each grain mix by the proportions of each ingredient in the mix (this should sum to the total parts). The total ration will be 55% grain mix A (40% corn and 60% SBH) and 45% grain mix B (50% DDG and 50% CSH).: -----a. 0.22 * (40 ÷ 100) = 0.09 parts corn -----b. 0.22 * (60 ÷ 100) = 0.13 parts SBH -----c. 0.18 * (50 ÷ 100) = 0.09 parts DDG -----d. 0.18 * (50 ÷ 100) = 0.09 parts CSH For grain mix A: 0.09 parts corn ÷ 0.4 total parts = 0.225 0.13 parts SBH ÷ 0.4 total parts = 0.325 For grain mix B: 0.09 parts DDG ÷ 0.4 total parts = 0.225 0.09 parts CSH ÷ 0.4 total parts = 0.225 5) Finally, go back and check the math as follows: 0.225% corn * 2.01 Mcal/kg = 0.45 Mcal/d 0.325% SBH * 1.37 Mcal/kg = 0.44 Mcal/d 0.225% DDG * 1.97 Mcal/kg = 0.44 Mcal/d 0.225% CSH * 0.48 Mcal/kg = 0.11 Mcal/d 0.45 + 0.44 + 0.44 + 0.11 = 1.44 Mcal/d = Orig. req. 6) Now, calculate how much of each feed ingredient to use in a 1,000-pound batch. Because the energy concentration is in Mcal/kg, first convert 1,000 pounds to kilograms (see conversion section below for directions). So, 1,000 lb = 454 kg 454 kg * 0.225% corn = 102.2 kg corn 454 kg * 0.325% SBH = 147.6 kg SBH 454 kg * 0.225% DDG = 102.2 kg DDG 454kg * 0.225% CSH = 102.2 kg CSH 102.2 + 147.6 + 102.2 + 102.2 = 454.2 kg (1,000 lb of mix)

Using a Pearson's Square

1)The value in the middle of the square must be intermediate between the two values that are used on the left side of the square. For example, the 14 percent crude protein requirement has to be intermediate between the soybean meal that has 45 percent crude protein or the corn that has 10 percent crude protein. If barley is used that has 12 percent crude protein and corn that has 10 percent crude protein, the square calculation method will not work because the 14 percent is outside the range of the values on the left side of the square. 2)Disregard any negative numbers that are generated on the right side of the square. Be concerned only with the numerical differences between the nutrient requirement and the ingredient nutrient values. 3)Subtract the nutrient value from the nutritional requirement on the diagonal and arrive at a numerical value entitled parts. By summing those parts and dividing by the total, you can determine the percent of the ration that each ingredient should represent in order to provide a specific nutrient level. Always subtract on the diagonal within the square in order to determine parts. Always double check calculations to make sure that you did not have a mathematical error. It also is very important to work on a uniform basis. Use a 100-percent dry-matter basis for nutrient composition of ingredients and requirements and then convert to an as-fed basis after the formulation is calculated.

Livestock producers use visual observations to

1. Select breeding cattle or swine based on conformation, breed character, structural soundness of feet and legs, and body capacity. 2. Select market animals based on muscle, frame size, body capacity, finish and structural soundness.

To use a Pearson's square

1. Subtract the nutrient requirement (middle of square) from the nutrient concentration (on left of square) in the feed across the diagonal (top left - middle = bottom right; bottom left - middle = top right). Repeat this for both feeds. Make any negative numbers on the right side of the square positive. The answers on the right side of the square are the parts of each feed to include in the ration. 2. After subtracting across the diagonal, sum the parts of the two feeds to get the total. 3. Then, divide each part by the sum of the parts to calculate the percent of each feed in the ration.

Considerations for livestock rations

1.) It should be palatable (taste good)... without mold, insect damage, and/or weather damage. 2.) it should be economically feasible because about 75% of production costs are related to feed. 3.) ingredients cannot be harmful to the animal or lower the quality of the product. 4.) balance intake of roughage's and concentrates for a specific animal.

The fire leaves behind empty, but not destroyed soil.5. Grasses and other herbaceous plants grow back first.6. Small bushes and trees begin to colonize the public area.7. Fast-growing evergreen trees and bamboo trees develop to their fullest, while shade-tolerant trees develop in the understory.8. The short-lived and shade-intolerant evergreen trees die as the larger deciduous trees overtop them. The ecosystem is now back to a similar state to where it began.

Restraining animals properly

Securing animals safely can help you to avoid sprains, strains, slip and fall accidents, and other physical injuries. Large animals, such as cattle and horses, should be placed in stocks or stalls. Halters, hobbles or other restraints can also be utilized. Dogs can be muzzled and cats can be wrapped gently in towels. In extreme cases, a tranquilizer should be administered by a veterinarian.

Pearson's Square example

Subtract across the diagonal: a. 15% - 10% = 5 parts soybean meal b. 15% - 45% = 30 parts corn 2. Sum the parts: a. 5 parts soybean meal + 30 parts corn = 35 total parts 3. Divide each part by the total to calculate the percent of each feed to include: a. 5 parts soybean meal ÷ 35 total parts = 0.143 * 100 = 14.3% soybean meal b. 30 parts corn ÷ 35 total parts = 0.857 * 100 = 85.7% corn So, in a half-ton (1,000-pound) batch of this corn and soybean meal mix, 143 pounds of soybean meal and 857 pounds of corn are needed to achieve 15% CP in the mix (calculations shown below). Soybean meal: 1,000 lb * (14.3 ÷ 100) = 143 lb SBM Corn: 1,000 lb * (85.7 ÷ 100) = 857 lb corn

T/F : Any carcass in need of further diagnosis or disposition is segregated and the veterinarian summoned.

T

T/F : Standards and grades can lower costs in the supply chain, by creating uniform products that flow through the system, regardless of the channel.

T

T/F : The establishment must ensure that the retained carcasses do not enter the food supply until it is released by FSIS inspection program personnel.

T

T/F : Without grades and standards, costly inspections are needed because the biological nature and perishability of these commodities make product consistency difficult to specify on an ad hoc basis.
