ANS 41L Long Report about Sheep Industry The sheep facility we visited was started in 1880. It is a commercial sheep farm, which only has no purebred sheep. There are about 1300 ewes and 37 rams. Most of the sheep are crossbred with Rambouillet and Dorset genetic. All of them are white face sheep. The crossbred they have is to improve meat quality. Also, the way to choose ram is according to EPD value. Comparing the data we collect from the producer to the America Sheep Industry Association Survey 2010 data, we can find that some values are quit similar. For example, ASI 2010 survey shows that percentage of lamb born per ewe is 158.65%，and percentage of lamb wean is 145.80%. This sheep farm we visited have a 140% lambing and weaning percentage. There are still many differences. The breed this sheep farm has are only white face breeds. According to ASI 2010 survey, it show that producer on average keep 13.3% Suffolk and 9.5% Rambouillet in their flock. Suffolk is black face sheep. However, this producer keeps none of black face sheep. The producer gives reasons for why they have white face sheep instead of black face sheep. White face breed have longer longevity and better wool. They have relative less problems. So it is easier for them to keep white face sheep on the farm. The farm also does better in some aspects compare to the average data collect by ASI (ASI, 2010). For example, their culling percentage is 10%, which is much lower than 19.42% from the ASI survey. Their lambing season is different from common sheep industry. They have spring and fall two lambing seasons. The breeding times matched to these two laming time are May and October. The advantage for having these two lambing seasons is that there will be more and better forage after the lamb coming out. Most of the sheep are fall lambing. According to Cruces’s article, there are three different seasonal breeding: spring, fall and winter (Cruces, 2001). However, spring may be a better season for lambing than fall because it follows the sheep’s breeding and lambing time. Higher lamb crop will be expected in spring than fall (Cruces, 2001). Also, fall lambing will have more heat stress to deal with. However, this producer did not mention how he solves this problem. This farm did not use AI for breeding. AI is not common used by sheep industry. Although, AI can use frozen ram semen, which may benefic in reproduction, it is still too costly because the producer said that AI in sheep needs surgical procedure (Cruces, 2001). Castration and tail docking time are similar to common sheep industry. This farm does these procures early on one to two days age. Cruces stated that these procedures should be done by 7 to 10 day of age, the early the better (Cruces, 2001). The producer sated that it is less painful and faster recovery if the procedures are done at very early age. There are two aspects impressing me very much: grain-growing work with sheep rising and electrical recording system. One third of the total area is used to grow grain, depending on the seasons. The rest of the acres are pastures for sheep. The producer use sheep to clean up the field after the grain harvest. Sheep can clean up the left over, as well as the weeds. It is a very clever system because the sheep and grain production benefit each other. They can spend less time, money and energy. Also, the electronic microchip recording system amazed me. The ear tagging not only contains the number to show the identification of the sheep but also records the data of the sheep. When the producer scans the ear tagging, it will show the information of that sheep. It is a very convenient way to track each sheep, and the data is very easy to assess. However, the operation is still facing many challenging. As the…

Title:Lab report of the constant of elasticity
Elasticity experiment report
In physics, elasticity is the tendency of solid elastomeric material, while after deformation recovering to the original shape. And spring is one of the elastic objects which can return to the original size when forces…
dv and what the differences are between them were, also that there are other factors that contribute to an experiments that could have and effect on a experiment/ results. During the duration of this particular module py0005 I have learnt what a lab report entails, memory and the different types such as chunking, levels of processing etc. Many aspects of work learnt during the duration of this particular module I had to learn independently, this meant doing further reading as suggested by lecturers…
Lab Report: pH Solutions
September 26, 2014
In this lab we measured pH using a variety of methods and materials. After the solutions we tested them with an indicator. By using the indicator we developed a concept of how each solution differed in relation to the pH scale.
Water: We used indicator paper to determine its pH. When tested by placing the indicator paper in the water, we found out that water has a neutral pH because it turned the indicator…
Date: April 1, 2014
Purpose: The purpose of this experiment was to introduce the chemistry student to basic laboratory procedures, demonstrate a working knowledge of the equipment and all safety features, and to perform simple lab procedures and compose a lab report at the conclusion of the exercise.
Observations: The glass tubing was heated over an open flame for 28 seconds before it was able to bend into a 90 degree angle. The beaker of water was initially 22 degrees Celsius, however, after…
Stoichiometry Lab Report
Karla WadeChoza, Jonathan Guerrero, Luis Martinez
March 11, 2013
In this lab, we mixed together the reactants, 0.05 moles of baking soda and some vinegar into a flask. The
products were the carbon dioxide, water, and sodium acetate. After mixing these chemicals together, we
boiled the flask until all the liquid in the solution was gone.
The purpose of doing this experiment was to practice using stoichiometry in a real lab…
ANATOMY & PHYSIOLOGY CLASS: WRITING LAB REPORTS
The following is an explanation of the format that is to be used for writing lab
reports. There will be lab activities for each Chapter in the textbook.
1. Lab Report grades are given the same value as a test grade. It is very
important that they be done correctly and thoroughly.
2. All lab reports should be typed using Times New Roman and only 12 font.
3. In the upper left hand corner include your name, high school, and A & P…

How Sound Levels Attenuate with Distance
For our lab we had to how distance affects the loudness of saxophone used. A decibel is a unit used to measure the intensity of a sound. Researchers would be interested in this information. Especially doctors dealing with patients who have a loss of hearing. The way we had done this experiment is by setting 10 meters of tape, each person stands on a meter with their cellphone.…
CHM1032L pre/post lab instructions
Preparation is a key to success in this lab. For this reason, you are required to thoroughly read through the experiment information presented in the lab manual, and complete a pre-lab for each experiment you do. The prelab must be completed prior to the day of the experiment. Each Friday I will ask to see your completed prelab before I allow you to enter the lab. If you have not finished the pre-lab, I will not allow you to enter the lab and you will receive…
