Yearling fed cattle spent 116 days on feed for both the CON and NOT groups. Cattle were weighed on day zero and on day 116 to calculate the information. In the CON group, cattle had an ADG of 3.76 lb/day. This was a higher ADG than the NOT group, who averaged a substantially lower rate of gain at 2.9 lb/day. In the end, this made a difference of 103 pounds in the finished body weight of cattle since the CON group finished at an average weight of 1260 pounds and the NOT group finished at a weight of 1157 pounds. To get the same body weight in the NOT group as the CON group, one would have to feed an extra 35.5 days. This research shows the importance of GETs in the beef industry. By looking at the increased productivity of the CON cattle over …show more content…
Hess, T. Hubbell, D. Hufstedler, G. D. Fieser, and B. Caldwel set out on their research to analyze the additive effects of growth promoting technologies on performance of grazing steers and economics of the wheat pasture enterprise. The objective of this research was designed to evaluate the effect of monensin (Elanco Animal Health, Greenfield, IN) supplementation via mineral or pressed protein block with or without a growth promoting implant on the performance of steers grazing wheat pasture. Through this study they were able to look at the effects of these two mineral supplements, with or without steroid implants, on ADG. To do this, they set up three treatment groups: one on a non medicated mineral, which was the control (CNTRL); another on a medicated mineral of 1.78 g monensin/kg, which was group RMIN; and the third group on a protein packed mineral with 0.33 g monensin/kg, which was group RBLCK. Each of these groups were divided in half and implants were put in one-half. There was a total of 360 animals used in the experiment over the course of two years, 120 each spring, and 60 each fall. These were then split equally into the three groups, CNTRL, RMIN, and RBLCK. These groups were each split again with implants put in half of the animals in each group. These groups were then left on pasture for the duration of the test with free access to the mineral supplement of their group. Weights were collected before and after the designated time spent on pasture. From this, they could calculate the ADG of the different groups. They then compared the difference in ADG between CNTRL, RMIN, and RBLCK as seen in table

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 National Cattlemen’s Beef Association is a trade association and policy group that represents all segments of the cattle industry: producers, feeders, and breeders. The association has over 28,000 individual members and represents over 230,000 people in the industry. The current president of NCBA, Scott George, is a cow/calf producer from Wyoming with a long history in the dairy industry and policy groups as a member of the Farm Bureau. In addition to its role in U.S. policy, the NCBA conducts research, marketing, and promotional work for cattle ranchers. The NCBA’s vision is “an industry united around a common goal of being the world’s most trusted and preferred source of beef and beef products.” The economic interests of the cattle
Cows who are on grass tend to not produce nearly as much but it is proven that the less milk a cow produces, the more vitamins in her milk. This is because a cow has a set amount of vitamins to transfer to her milk, and if she’s bred, fed, and injected to be a Super Producer, her milk has fewer vitamins per glass. It is a watered down version of the real thing. (Super Natural 1)
f. The student is conducting a nutrition experiment using lab rats. One group (control group) is fed a normal diet, while the other group (experimental group) is fed a diet high in protein. There were 30 rats total used in the experiment. At the end of the experiment, the average mass (weight) of a rat in the control group was 60.4 g while the average mass (weight) of a rat in the experimental group was 0.0689 kg. What is the average difference in weight between the two groups in grams?
A Brief History of Agricultural in the 21st Century and how it applies to grass fed Beef
To minimize the N.E.B the cow should be in the correct body condition before calving down, a score of 3.0 is appropriate. If the cow is too fat the she will not have the appetite to eat in early lactation which will affect the peak milk yield. It is key that the food intake is maximized post calving therefore the cow should have ad libitum access to forage at all time, the forage should also be of a high quality in early lactation, this is not as important when you move down the cycle. To overcome any limitations of forage concentrates like Molasses and Maize should also be used. A good concentrate mix for a dairy cow should contain starch sources of varying degradabilites, Molasses is rapidly degradable source while maize is a slowly degradable source of starch. There are two methods for feeding concentrates, in parlour and out of parlour. In parlour feeding systems the parlours are fitted with concentrate dispensing hoppers which dispense into the feed manger. A cow will receive 5kg per milking while a heifer will receive 4kg per milking. Out of parlour feeding is where feed is given out by transponders, in small amounts very often. Picture 1 shows an in parlour feeder system.
Statistical analysis for the animal studies. Our selection of 10 animals per time point is based on the group variance observed in our preliminary studies employing diet models. For example, an n = 10 provides 95% power (alpha of 0.05) to detect differences in ALT values of at least 30 U/L between two means with a standard deviation of 10 (two-tailed t-test). For endpoints such as ALT values, caspase positive cells, etc., in different animal populations, parametric analysis will be performed. ANOVA will be employed given the presence of multiple groups, and a Bonferroni test will be used to correct for multiple comparisons. If the distribution of values is unsuitable for a parametric analysis, we will perform a Kruskal-Wallis test for nonparametric data. If the data show a strong trend towards significance (e.g., p < 0.1) with reproducible data except for a rare outlier, we can consider increasing the number of animals per group. The number added will be calculated using the mean and standard deviation (SD) from the existing data
In conclusion, the amount of stress on cattle can reduce production in all aspects and ultimately leave the farmer empty handed and the consumer can be left with rotten, tasteless food. Stress must be reduced to a minimum to bring forth the best most profitable product. Perhaps all farmers should shoot for having cattle be that stereotype of easily soaking up the sunshine and lying on a side hill chewing cud. What is the cost of stress? Can the reduction of stress bring a better life to all aspects of the beef industry? Will the reduction of stress create a better product for consumers? What is the real cost of

The owners of the farm have found a correlation between the weight of a cow, and the cost of feeding it, in
The cattle industry produces vast amounts of strain in the environment. It is energy inefficient, pollutes water, occupies many acres of land, and deteriorates the health of the people who abuse its consumption. The government subsidizes this industry. Therefore, the price paid for meat doesn’t reflect the environmental hazards involved in the process. In order to protect our health and the health of the environment we should pay close attention to our food choices and make sure we don’t support industries that degrade it.
For the modern dairy farmer, the perception that the public has regarding the industry has a significant impact on their overall wellbeing as a company. However, most people in modern society have little personal experience with farming, and their opinions are often based on second-hand information (Boogaard et al. 2010). In general people are more concerned with the welfare of the animals and want them to be able to display natural behaviours like grazing on pasture for most of the day (Cardoso et al. 2016). This however, can prove very problematic for dairy producers as it results in lower control over feed intake and body condition score of the cows. Body Condition Score (BCS) is a management tool used to assess body fat stores in dairy cows (Ferguson et al. 1994). It has been correlated with overall reproduction, health and productivity of dairy cows at it is considered one of the most practical methods of assessing changes in energy stores (Berry et al. 2007; Bewley et al. 2008). However, due to its subjectivity and time consumption it is not a widely used management tool in the industry. There are many studies that try to use technology as a way of making an automatic system for BCS. This paper aims to identify the perspectives on the BCS from the public and the producer, benefits of using an automated BCS and current technologies available.
Result: a more consolidated meat industry comprising of companies with sophisticated manufacturing and marketing skills, stronger financial positions, and a focus on building value added brands and market share. The race was thus on for new ideas and promotional support to achieve industry leadership. If Om was to remain on top as one of the leading brands, then investments would be needed on promotion and advertisement as well as in research and development. There was a dire need to align the products with consumer trends and satisfy the target audience’s want for products that were faster and easier to use.
