Abstract
A poultry feedstuff contains a minor but effective amount of sorbitol, preferably 0.01 to 5% wt. The sorbitol is believed to act as an emulsifier for lipids in the feedstuff, and preferred feedstuffs have higher than normal lipid contents (e.g. 2.5-20% wt.).
Description
SPECIFICATION
Poultry feedstuff
This invention relates to a poultry feedstuff.
According to the present invention a poultry feedstuff contains a minor but effective amount of sorbitol.
The feedstuff may be used for any poultry (including turkeys and ducks) but is particularly suitable for broiler chickens (i.e. birds raised rapidly from day old chicks to birds of a weight suitable for consumption). It has been found that the addition of as little as 0.1% wt of sorbitol in the feed increases the growth rate (as measured by the average live weight gain per unit of time) and reduces the Feed
Conversion Ratio (FCR).
Sorbitol is a hexahydric alcohol CeH,406 which is available commercially and which may be produced from glucose by high pressure hydrogenation or electrolytic reduction.
The amount of sorbitol may conveniently be from 0.01 to 5% wt, by weight of feed with, as indicated above, an effect being noted at a level as low as 0.1%. A preferred range is 0.01 to 1% wt.
The other components of the feed may be the normal components for poultry feed and include sources of carbohydrate, protein, lipids (i.e. fats and oils), fibre, vitamins, amino-acids, and minerals. The principles of poultry feeding are well understood in the industry and the term "poultry feedstuff" would be understood as differentiating the feedstuff from feedstuff for other livestock such as cattle or pigs.
Without being bound by any theory, it is believed that the beneficial effect of sorbitol results from the fact that it acts as an emulsifier for lipids and, thus, improves lipid digestibility. The use of sorbitol is particularly preferred with poultry feeds of higher than normal lipid content, e.g. feeds with from 2.5 to 20% wt of lipid.
The invention includes a method of feeding poultry comprising feeding to the poultry a feedstuff containing a minor but effective amount of sorbitol.
Other features of the feedstuff used may be as set out above.
The feeding pattern may follow standard practice. Thus, feeding will normally be ad lib with, for broiler birds, feeds being adjusted as the birds grow. For example starter and finisher feeds may be used with one or more intermediate feeds if required.
The invention is illustrated by the following comparative examples.
EXAMPLE 1
Three poultry feeds were made up from the following constituents: maize, wheat, soya meal, full fat soya, fish meal, fat, minerals, vitamins and amino acids.
The proportions were varied slightly to give Super Starter, Starter and Rearer Feeds with the following compositions:
Super Starter Starter Rearer
Lipid 6.5% wt 8.3% wt 8.0% wt
Protein 22.7% wt 20.7% wt 18.0% wt
Fibre 2.9% wt 2.9% wt 2.8% wt
Lysine 1.4% wt 0.26% wt 1.04% wt
Methionine and Cysteine 0.91% wt 0.87%wt 0.76% wt Metabolisable Energy 1390 KCals/lb 1420 KCals/lb 1450 KCals/lb
0.1 % wt of sorbitol was added to half of these feeds by adding it to the vitamin-mineral premix, which was then added to the mix in the normal way.
The feeds were used in an eight-house broiler chicken unit. Houses 1 to 4 (38,600 birds) were supplied with the feeds containing 0.1% wt sorbitol; houses 5 to 8 (38,529 birds) were used as control, being supplied with the same feed but with the sorbitol omitted.
All other features of the houses were the same (e.g. temperature and lighting for houses, quantity of feed supplied and water supply).
The birds were in the houses from day old chicks until they were removed for slaughter.
The data obtained on the birds was as follows.
Houses 1-4 Houses 5-8 Feed with sorbitol Feed without sorbitol Mortality(%) 4.42 3.93
Average live weight gain (Ib) 4.356 4.281
Age (days) 49.196 50.267
Feed Conversion Ratio 2.093 2.12
It will be seen that birds with sorbitol in their feed had a higher average live weight gain over a shorter period than the birds without sorbitol in their feed. In economic terms the cost of the sorbitol was returned six-fold.
EXAMPLE2 Trials were carried out to assess the effect of sorbitol on the Metabolisable Energy content of tallow when included in broiler chicken feed. The chicks were fed a starter mash from 0-7 days and the experimental diets from 8-21 days. Droppings were collected, weighed and sampled on days 1 7 to 21 to determine the influence of sorbitol on Metaboiisable Energy. Chicks were weighed at days 8, 15 and 21.
Diets were as follows:
1. Basal diet containing no added fat.
2. Basal diet containing 4% added tallow.
3. As Treatment 2, but including 500 g sorbitol (0.05% wt)
4. As Treatment 2, but including 1000 g sorbitol (0.10% wt)
Composition of basal diet is shown below.
g/kg
Ground wheat 619.69
Ground maize 52.08
White fish 26.04
Soyabean meal (50 CP) 219.79
Microbial Protein 52.08
Vitamin/Mineral Supplement 13.02
Dicalcium phosphate 9.38
limestone 5.21
Salt 0.73
DL-Methionine 0.94
Lysine 1.04
1000.00
When 4% wt of tallow was added to this basal diet, a corresponding proportional reduction was made to the content of wheat, maize, fish, soyabean meal and microbial protein. The microbial protein was that sold by ICI Limited under the Registered Trade Mark "Pruteen".
The results are shown below

The results show an improved live weight gain per bird when going from Diet 1 to Diet 4 and a corresponding lower feed conversion ratio. The metabolisable energy of the tallow was increased by the addition of sorbitol to the diet.
