The omasum has many folds of tissue, similar to a partially open book, and contains from 6 to 8 percent of the total digestive tract capacity. After sufficient time in the reticulo-rumen, digesta flows into the omasum. The reticulo-rumen contains more than 30 percent of the total digestive tract capacity and most of the microbial activity takes place here. Digesta can flow freely between the first two compartments, the rumen and reticulum. The ruminant stomach is divided into four compartments: the rumen, reticulum, omasum and abomasum. The ruminant digestive tract and the ruminant stomach are shown in Figure 1. The cow has the stomach volume and properties necessary to assist with the microbial digestion. In cattle and sheep, rumen microbes supply the digestive enzymes necessary for the breakdown of plant cellulose and hemicellulose. Forage consuming species, such as cattle and sheep, have intestinal differences which enable them to digest large amounts of fiberous material. Monogastric animals do not produce enzymes capable of breaking down cellulose, the main source of energy in forages. The monogastric stomach is a pouch-like structure containing glands which secrete hydrochloric acid and digestive enzymes. Man, dogs, poultry and swine have simple or monogastric stomachs (see Figure 1). The relationship of the microbes wiht the host cow is mutually beneficial. The microorganisms also pass from the rumen to the lower digestive tract, where the are digested and their constituent protein, vitamins and other nutrients are absorbed and utilized by the animal. These by-products are absorbed into the blood and are used as sources of nutrients by the animal. In this process, various microbial by-products of no value to the microbe, such as volatile fatty acids and B vitamins, are produced. Microorganisms in the rumen have the unique ability to break down fiberous feedstuffs to obtain the simple nutrients required for their growth. Cattle can utilize roughages and other fiberous feedstuffs only through the action of microorganisms which are normally ingested on feed or obtained from other animals.

Have one sausage and one bacon rasher, instead of two of each, in your full English breakfast – add another egg and extra beans if you're hungry.Whitney Rounds and Dennis B. If you love bacon, fry one rasher until crisp, chop into pieces and add to a salad, omelette or pasta dish.ġ0. In sandwiches, swap salami, ham or other processed meats with canned tuna, sardines or mackerel, or use roast chicken.ĩ. Add cheese! Simple roasted vegetables taste amazing sprinkled with a strong cheese, such as mature cheddar, towards the end of the cooking time.Ĩ. Opt for Indian, Middle Eastern or South-East Asian veg dishes that use loads of spices and herbs – you're less likely to notice the absence of meat.ħ. Buy meat less frequently but make it the best quality you can afford.Ħ. For example, consider eating meat only on weekends, or restricting meat to one meal per day.ĥ. After soaking dried mushrooms (such as porcini and shiitake) in hot water, save the soaking liquid to use in stocks to add a ‘meaty’ flavour.Ĥ. Devise a way of curbing your meat intake that works for you. Use vegetables with a ‘meaty’ quality, such as mushrooms and aubergines.ģ. For example, reduce the amount of meat in stews and curries, and bulk up with extra vegetables, pulses and grains.Ģ. Build meals around vegetables and add a little meat in, rather than the other way around. A healthy, balanced diet can include protein from meat, as well as from non-animal sources such as beans and pulses. Moderation is the key.

If you eat a bacon sandwich once a month, then there's no need to worry. Aim to have oily fish such as mackerel, herring, sardines and salmon once a week. These are great sources of healthy omega-3 oils. Making small swaps to your diet can help without making radical changes. Aim to have red meat just once or twice a week and swap processed meats for lentils, chickpeas, kidney beans, peas, butter beans, baked beans or haricot beans. These are less expensive, high in fibre and lower in fat. Swap lamb or beef mince for turkey or vegetarian mince in spaghetti Bolognese, lasagne and chilli con carne. Introduce more white fish such as cod, coley and haddock. If you’re eating more than this, cutting down isn’t as hard as you may think. It's also best to reduce your intake of processed meats where possible.

The NHS recommends that those who regularly eat more than 90g of red or processed meat each day should reduce this in light of the possible associations with colon cancer risk.
