...PROCESSED & PACKAGED MILK INDUSTRY IN PAKISTAN (IN THE CONTEXT OF ENGRO FOODS) Introduction Pakistan is the fourth largest milk producer in the world. Pakistan produces 45 billion liters of milk annually. However, only 36.2 billion liters of milk are usable, as 20 % of this milk goes waste owing to inappropriate methods of storage and lack of timely transportation. Engro Foods is asubsidiaryof Engro Corporation.In 2005,Engro decided to diversify their business by venturing into the food business by establishing Engro Foods Limited. Engro Foods offers a number of products namely, Olpers, Tarang, Olwell, Omore, Owsum, Olfrute, etc., with representative market share of 33% in Pakistan. Engro Foods has two production plants situated at Sukkur and Sahiwal with different combination of products manufactured at each plant. Dairy Milk Industry in Pakistan Milk is amongst the most important consumable and marketable commodities of the world with enormous demand in domestic and international markets. Buffalo is the main source of milk in domestic dairy industry, whereas cow is the main source of milk in international market. Pakistan is the fourth largest milk producing country in the world. 80% percent of milk is produced by farming families from small herds of buffaloes using locally produced feed. They account for 11 % share in the Gross Domestic Product, employ 30-35 million rural people, and constitute 30-40 % of their income. Almost all rural families, especially...

The cattle was often fed in grains, the animal we ate have been evolution by roamed free and ate grass. Many studies that had shown the nutrients in beef can be varying depending on how cow eat. It not only important how we eat, it is important the food we eat. What the different between grass-fed and grain-fed cow? All cow starting live similar life. Once calves were born, they start drink milk from their mother. Calves starting to roam and eat grass, shrub or whatever edible plants they find in their environment. This continues for about six to eighth month, and then the farmer will conventionally raise cows to feedlots. Large feedlot are called Concentrated Animal Feeding Operations ( CAFOs). That where the crowing cow is and their dung on their feet. The farmer has feeding grain-based to the cow to rapidly fatty up. The grain-based was base of soy or corn. The conventionally of cow grow faster by given drugs and hormones to grow faster, and antibiotic to survive the unsanitary living condition. The cow will be staying there for few month then move into factory for slaughtering. Grain-fed beef does not contain appreciable levels of carotenoids, for the simple reason that grains don’t contain them. Compare that to grass-feeding cow, which the cow may continue to live...

Even today Western medicine is indebted to indigenous medicine for the most commonly used anaesthetic derived from Coca .A plant that South American Indian doctors have used for this purpose since pre-Colombian times. Indeed there are numerous plants of both south and North American Native origin that have enriched modern western herbalist and medicine. However, in Native traditions it is not just the plant that makes the medicine, but foremost the power of the spirit that governs the plant. A plant as such would be considered useless unless it were gathered and prepared with due respect, prayer and rituals with which the healer seeks the support of the plant spirit to help him affect a cure. Native American Medicines: Even though, Native American Medicines have no real threat to our bodies. Are Native American Medicines better for us than Traditional medicines with no side affects because Native American Medicines have been around for years and are still being used today and Native American Medicines have no real side affects like traditional medicines do. The most important reason are Native American Medicines better for us than traditional medicines, like pain killers, or others is because Native American Medicines have been around for years and are made from plants and roots from their region. In conclusion, although Native American Medicines have not real threat to our Bodies. Are Native American...

(see chapter 3) *What is the optimum strategy? = Energy maximization or time minimization Max En/T Assumptions about the predator (forager): -Eating and searching for the next food (prey) item are mutually exclusive activities. -Items are found sequentially, items are found one at a time. Energetic Value of prey: EACH PREY ITEM HAS AN ENERGENTIC VALUE (ei) Handling time: A HANDLING TIME (hi) Profitability: : e/h= profitability of each prey item (such that prey can be ranked) Rule: optimal foraging rule (prediction) – always eat the most profitable prey and eat the next most profitable prey if the gain is greater than the gain from rejecting it and searching for a more profitable prey. Predictions of Optimal Foraging Theory: The highest ranked prey type should always be eaten when encountered. 1) Predators with small handling times and long search times should be GENERALISTS. 2) Diets should be broad in pre-poor (unproductivr) environments. 3) The abundance of low ranking prey types is unaffected by the a abundance of the low-ranking prey is irrelevant.

...Water pollution Water pollution is the contamination of water bodies (e.g. lakes, rivers, oceans, aquifers and groundwater). Water pollution occurs when pollutants are discharged directly or indirectly into water bodies without adequate treatment to remove harmful compounds. Water pollution affects plants and organisms living in these bodies of water. In almost all cases the effect is damaging not only to individual species and populations, but also to the natural biological communities. Introduction Water pollution is a major global problem which requires ongoing evaluation and revision of water resource policy at all levels (international down to individual aquifers and wells). It has been suggested that it is the leading worldwide cause of deaths and diseases, and that it accounts for the deaths of more than 14,000 people daily. An estimated 700 million Indians have no access to a proper toilet, and 1,000 Indian children die of diarrheal sickness every day. Some 90% of China's cities suffer from some degree of water pollution, and nearly 500 million people lack access to safe drinking water. In addition to the acute problems of water pollution in developing countries, developed countries continue to struggle with pollution problems as well. In the most recent national report on water quality in the United States, 45 percent of assessed stream miles, 47 percent of assessed lake acres, and 32 percent of assessed bays and estuarine square miles were classified as polluted...

...their actual business practices are contrary to those standards. Chipotle, one of the fastest growing chain restaurants, is no stranger to this controversy. The company has made great strides in offering “Food with Integrity” yet it still lacks in credibility. This paper will analyze Chipotle’s CSR and how its standards have led many to question the company’s core values. Chipotle's CSR: Mission or Marketing? The heightened media attention on CSR is at least partially in response to society’s interest in socially conscious businesses. Consumers are willing to pay a premium price for environmentally-friendly brands. At the same time, there is much skepticism as to whether companies are intentionally or accidently misleading consumers. Chipotle, one of the fastest growing fast-casual restaurant chains in the world, declares it serves “Food with Integrity”. What does that mean? The company’s reputation has taken some hits in recent years due to lack of transparency. Lessons have been learned along the way yet there is still a credibility gap. Many wonder if Chipotle is telling the public a feel-good story or the truth. This paper will take a look at the company’s CSR: intent vs. execution vs. depiction.

...Chapter 1: • Name four properties that all life forms have. Order, Regulation, Growth and Development, and Energy Processing 2. Briefly discuss Darwin’s theory of Natural Selection. The process of descent with modification is Darwin’s take on evolution. The mechanism he proposed for this was called natural selection, which is another way of saying unequalled reproductive success. First, he observed overproduction and competition. Next, he observed individual variation. Finally Darwin concluded unequalled reproductive success, or those best suited for the surroundings survived. 3. What is the difference between a hypothesis and a theory? A hypothesis is an uncertain answer to a question, therefore untrue, and able to be tested. Another way to look at it is a judged explanation. A theory has a much broader scope than a hypothesis.
