A recent article published using data from Tunisian dairy herds provided this information on milk productivity for an individual dairy cow: Item ? (mean) ? (std. dev.) Minimum Maximum Milk, kg/cow/year 4500 850 1900 7500 The study noted that annual milk production per cow follows a normal distribution. a) What is the amount of milk produced by a cow just at the first quartile (25%) of milk production? (keep 1 decimal) kg/cow/year. b. What are the lower and upper values of milk production that would be associated with the middle 68 percent of the distribution? (no decimal) lower: kg/cow/year. upper: kg/cow/year. c. Bagra is a wildly popular mobile cellphone game. The game involves trying to steal cows from other competitors, while keeping your herd intact. Last year, the BBC reported from Tunisia about a Tunisian couple who had triumphed at the game and were rewarded with Pamela the cow. After a few months, the couple claimed Pamela was producing a whopping 6,500 kg of milk per year. What percentage of Tunisian cows produce less milk than Pamela? (keep 1 decimal, in %, i.e. 1.1%)

The problem provides information about the milk production of dairy cows in Tunisia, which follows a normal distribution. We need to find: a) The amount of milk produced by a cow at the first quartile (25%) of milk production. b) The lower and upper values of milk Show more…

In 1983 the Department of Dairy Science at the Virginia Polytechnic Institute and State University conducted an experiment to study the effect of feed rations, differing by source of protein, on the average daily milk production of cows. There were 5 rations used in the experiment. A $5 \times 5$ Latin square was used in which the rows represented different cows and the columns were different lactation periods. The following data, recorded in kilograms, were analyzed by the Statistical Consulting Center at Virginia Tech. At the 0.01 level of significance can we conclude that rations with different sources of protein have an effect on the average daily milk production of cows?

Case Study
4-31 Dairy cows in most countries calve on a regular annual basis. Their milk output varies over the year accordingly, with a peak reached a few months after calving followed by a decline to almost zero in the tenth month. Knowing these facts, farmers in an agricultural cooperative are trying to plan calving months c = 1, . . . , 12 to make it easier to meet seasonal milk demands rd pounds in months d = 1, . . . , 12. Any milk produced beyond these demands must be sold on the bulk market at b per pound below the regular price. The annual cost mc of maintaining a cow calving in month c varies significantly over the year because low-cost grazing is available only in certain seasons. From scientific studies the farmers can estimate the yield pd,c pounds in demand month d per cow calving in month c. Formulate an LP model to determine a minimum total cost calving schedule using the decision variables (c, d = 1, . . . , 12) xc ≜ number of cows calving in month c yd ≜ pounds of excess milk produced in demand month d

Milk is flowing like never before in the U.S., where dairies have expanded output enough to send wholesale prices plunging from an all-time high in September. Production in the 12 months through October reached 17.08 billion pounds a month on average, up 1.8 percent from the same period a year earlier, as farmers took advantage of high milk prices and low livestock-feed costs, government data show. Two years of record corn harvests in the U.S. sent grain prices to a five-year low. Grains are mainly used as feed for cow farmers. Imports of milk to the US has also increased during the period as countries such as New Zealand are also benefiting from good market conditions During this time however, demand for the good has not been able to keep up with the supply. Notably, the current market conditions are not expected to last with impending drought conditions that would impact the harvest of corn and result in an increase in its price. With higher prices for grains some farmers may no longer be able to afford to keep their current livestock and they may resort to selling their cows to be butchered for beef. With the impending drought conditions illustrate and explain what will happen to (i) the market for milk and (ii) the market for beef. Explain how revenue for both milk producers and beef producers will be impacted by the drought conditions.
