Define an ideal protein. Explain the concept of using dietary proteins to provide the "ideal protein" in the diet. Choose 2 or 3 feed ingredients to give an example of using the concept.

An ideal protein is when an amino acid meets the requirements an animal has for the amount they need. When using dietary proteins in a diet, it helps give an animal the required amount of amino acids they need. Generally with pigs, the most common feed ingredients for ideal proteins is soybean meal and and another, not so common one is fish meal. These are both put in diets of pigs to make sure they get what they need, and nothing extra. Another word for that is they get the required amount for their bodies.

Describe in detail a potential health complication that could affect grazing animals. Include cause, symptoms, and possible prevention/treatment strategies

Bloat is one of the potential health complications that can affect grazing animals, generally ruminants which can be fetal. (But not horses due to how they're built). A cause could be from feed being too dry and being hard to digest. But this is when gas gets completely trapped in the stomach and cannot get out. Symptoms can be like wrenching - they look like they want to vomit or are acting like they're trying to get something up, laying down - not wanting to get up, and sometimes foamy mouth. It's a hard one to prevent because it isn't the most common to occur, but treatment plan is getting the veterinarian out and possibly surgery

You have the following information on energy values for wheat bran fed to pigs. Digestible energy, 2.42 kcal/g; and Metabolizable energy, 2.28 kcal/g. The Gross energy is 4.1 kcal/g. Explain what each of these values is and why the values differ.

DE=2.42 - DE is the intake energy minus the energy loss by feces ME=2.28 - ME is the DE minus the UE (Urine loss) + GasE, which means that it's generally more accurate than DE. This includes urine and gas loss compared to just feces loss. GE=4.1 Gross Energy is the amount of energy loss These values differ because they do include different substances to get their specific type of energy. Some animals might defecate more than urinate and vise versa, which can cause the numbers to differ as well. Also how some animals can't be used for these values... examples of this is how the chicken cannot give us a DE because they tend to drop feces and urine together, and we are unable to separate them. Also how the horse cannot give us an ME value because not enough trials have been done for any true value.

Cow

Dry off - 60 days colostrum - contains antibodies that are important for passive immunity Heifer diet - dry matter intake, protein intake, and energy intake shows that as the calf grows in body weight her intake increases dramatically. more protein young to mature, then declines Mixed ration benefits - all feed ingredients are included in one mix and nutrient requirements are met bypass protein - less likely to be digested by rumen microbes and goes directly to the abomasum for digestion fresh cows can get - milk fever, retained placenta, ketosis, fatty liver fibrous feed - silage, hay, cottonseed hulls, corn cobs 65% dietary protein goes towards digestion fats provided by - grease, tallow, oils, oilseeds

Nursery site = many housing in group pens and they stay for stay about 6 to 7 weeks all in all out - control disease by breaking the reoccurring pattern of disease transmission. pigs are moved all in a room together and all out together. No contact with other groups phase feeding - continuously different diets depending on their age and nutritional/physiological status feed acidifier - to keep the health of nursery pigs after weaning split sex feeding - reduce fat gain and enhance lean gain feed intake restricted for sows - bc they will have difficulties with farrowing and producing enough milk for the piglets

List and identify one ruminant and one simple stomached animal. Give 2 specific examples of differences in carbohydrate digestion (not including the mouth) between your 2 animals. Specify the location in the GI tract for each example.

One ruminant is a cattle and one simple stomached animal is a pig. The cattle is able to use rumination to make sure carbohydrates do actually get dissolved in the rumen.
