These quantities are based on the assumption that the essential amino42 Nutrition of non-ruminants
acids will supply at least 45% of the total amino acids and that the
essential amino acids will be balanced according to the recommendations
of Wang and Fuller (1989) (Table 3.1).
The fact that the regression coefficients linking protein supply with
liveweight gain were almost the same for cassava root meal and sugar
cane juice (Figure 3.1) indicates that probably other low-protein,
low-fibre energy feeds will respond in a similar manner.Support for this
hypothesis is found in the results with oil-press fibre (30% oil; zero
protein) fed as the basal diet to fattening pigs (Ocampo et al.,1990b).In
an experiment with levels of from 500 to 1,000 g/day of a fortified soya
bean supplement (soya bean meal with added minerals and vitamins)
(200 to 400 g/day protein),there was no biological advantage from
giving more than 200 protein g/day throughout the growing-fattening
(20-90 kg) period.
It is interesting,in the light of the above recommendations,to refer
to an experiment carried out over 30 years ago (1957/58) in Louisiana
State University by Thrasher et al.(1958).These researchers offered
growing- fattening pigs (from 24 to 90 kg) mixed diets with either 0,20,
30,40 or 50% raw sugar (replacing maize meal),balanced with soya
bean meal,meat meal and alfalfa meal to provide 16 declining to 14%
protein; a 6th group of pigs had free access to raw sugar,maize meal and
a protein supplement (36% protein from soya bean,meat meal and
alfalfa meal).Growth and feed conversion on all treatments were similar
(785 to 872 g/day; 3.1 to 3.4 conversion,air dry feed basis) but the pigs
on the free choice system only consumed 258 g protein/day,of which 95
g came from the maize and only 163 g from the protein supplement.
These same pigs consumed 45% of their diet as sugar.The pigs on the
mixed feeds consuming this same level of sugar (average of 4th and 5th
groups) consumed 400 g protein daily yet they performed no better than
the free choice group which consumed 36% less protein.
It is unlikely that,on all occasions,it will be possible to prepare an
"ideal" protein supplement with the perfect complement of amino acids.
For all practical purposes,the protein of soya bean is sufficiently close
to the ideal protein (see Figure 3.3) as to be the supplement of choice
where it is available or can be grown.
In fact,on small farms in remote areas,the availability of protein
sources may well be restricted to what can be grown on the farm or atTropical animal feeding:a manual for research workers 43
