(a) Mention two organs each in each of the following parts of rabbit: (i) head; (ii) thorax; (i) abdomen. (b) State one function of each of the following or...

(a) Organs in Parts of Rabbit:

(i) Head: Tongue, Eye, ear, lips, teeth, nose/nostril, Mouth/oral cavity/buccal cavity, Brain, Skin, Hair, Skull

(ii) Thorax: Lung, Heart, Oesophagus, Trachea, Diaphragm, Thymus.

(iii) Abdomen: -Small intestine - Large intestine -Pancreas -Spleen, Bladder, Uterus, Fallopian tube/oviduct, Ovaries, Kidney, Liver, Stomach, Caecum, Colon

(b) Functions of Organs:

(i) Caecum:

• It aids fermentation of fibre. 
• Absorption of fluid/salt/vitamins.
• Houses microbes which produce cellulase for microbial digestion.
• Site where digestion of forages take place in pseudoruminants.

(ii) Gizzard:

• Contains grit/stones for grinding feed in poultry/aids digestion.
• Stores feed in poultry/aids digestion
• Stores feed temporarily/regulation of feed flow.
• Mixes digestive enzymes with the feed/chemical degradation

(ii) Crop:

• Hunger sensation centre.
• Site for temporary storage of food feed/regulation of feed flow.
• Allows feed to be moistened for digestion/aids digestion.
• Acidification of feed.

(iv) Rumen:

• It facilitates rumination.
• Elimination of gases through eructation.
• Site for fermentation of fibrous feed.
• Houses microbes which facilitates digestion of fibre.
• Production of volatile fatty acids.
• Synthesis of vitamin B complex.
• Receives feed.
• It stores feed temporarily.
• Absorption of volatile fatty acids.
• Site of synthesis of microbial protein.

(v) Lung:

• Helps in intake of oxygen/breathing/respiration.
• Provide surface for gaseous exchange
• Helps in the elimination of carbon dioxide.

(c) Practical Way of Checking Malnutrition in Livestock Production :

• Deworming.
• Giving supplementary feed
• feeding weaker animals separately
• use of fortified feed
• adjusting stocking density
• feeding the animals adlibitum /without restriction
• Provision of quality feed.
• Avoid overfeeding/underfeeding
• Protecting animals from toxic plants.
• Provision of salt lick.
• Use of additives to stimulate feed intake. 
• Provision of good quality water
• Balanced ration/diet
