(a) A farmer fed some lambs wih eight different feed composition
Assuming the feed conversion Ratio (FCR) = Feed in take (g)
weight gain (g)
complete the table below
| feed | feed intake (g) | weight gain (g) | feed conversion ratio (FCR) |
| A | 252 | 42 | (i) |
| B | 500 | 100 | (ii) |
| C | (iii) | 36 | 6.2 |
| D | 840 | (iv) | 20 |
| E | 526 | (v) | 20 |
| F | (iv) | 124 | 5.8 |
| G | 1276 | (vii) | 20 |
| H | 1026 | 45.2 | (viii) |
(bi) Deduce from the table the feed with the
highest feed conversion ratio:
(bii) Deduce from the table the feed with the
lowest feed conversion ratio
(c) Name five product that could be obtained from farm animals
(d) list three chemical process involved in rock weathering
(a)
| feed | feed intake (g) | weight gain (g) | feed conversion ratio (FCR) |
| A | 252 | 42 | (i) 6 |
| B | 500 | 100 | (ii) 5 |
| C | (iii) 22.3 | 36 | 6.2 |
| D | 840 | (iv) 51.2 | 20 |
| E | 526 | (v) 26.3 | 20 |
| F | (iv) 719.2 | 124 | 5.8 |
| G | 1276 | (vii) 58 | 20 |
| H | 1026 | 45.2 | (viii) 22.7 |
(bi) Feed with lower value of feed conversion ratio(FCR) is an indication of faster rate of growth and efficient conversion of
feed to flesh, and vice versa.
Feed H has the poorest and highest FCR of 22.7 while feed B has the best FCR and lowest FCR of 5.
