a)(i) Explain the term monogastric.
(ii) Give two examples of monogastric animals.
(b) Explain each of the following terms as used in animal nutrition: (i) concentrate: (ii) additive.
(c) State four ways in which roughage is important in the diet of farm animals.
(d) List four materials which could be used in milking cow.
(e) Mention two animals each which could be fed on each of the following forms of prepared feed: (i) pellets: (ii) mash.
(a)
(i) Monogastric refers to animals with a single-chambered stomach that lacks the ability to break down cellulose, a complex carbohydrate found in plant materials. This means that these animals rely on other digestive mechanisms to break down their food.
(ii) Examples of monogastric animals include humans, dogs, and pigs.
(b)
(i) Concentrate refers to a type of animal feed that is high in energy and low in fiber, typically made from grains and oilseeds. This type of feed is often used to supplement the diets of animals that do not consume enough energy or protein from roughage alone.
(ii) An additive refers to any substance added to animal feed to improve its nutritional value, flavor, or appearance. Common examples include vitamins, minerals, and flavorings.
(c)
Four ways in which roughage is important in the diet of farm animals are:
- Provides fiber: Roughage contains high levels of fiber, which helps to promote healthy digestion and prevent digestive disorders.
- Encourages rumination: Chewing roughage stimulates saliva production, which aids in digestion and helps to prevent acidosis.
- Maintains gut health: Roughage provides essential nutrients that help to support the growth of beneficial bacteria in the gut.
- Promotes satiety: Roughage takes longer to digest than concentrate feeds, helping animals to feel full and satisfied for longer periods of time.
(d)
Four materials that could be used in milking cows include:
- Milk machine: a device that automatically milks cows by attaching suction cups to their udders.
- Milk bucket: a container used to collect milk by hand-milking.
- Teat dip: a disinfectant solution used to clean cows' teats before and after milking.
- Towels: used to clean the udder and teats before milking.
(e)
(i) Pellets are a type of prepared feed that is compressed into small, uniform pellets for easy feeding. Two animals that could be fed on pellets are rabbits and horses. Pellets are convenient to store and transport, and they provide a balanced source of nutrients for these animals.
(ii) Mash is a type of prepared feed that is ground into a fine, granular consistency. Two animals that could be fed on mash are chickens and pigs. Mash is easily digestible and provides a good source of energy and protein for these animals.
