What effect does dry matter of liquid feed have on FCR and growth rate?
Wednesday, 16 February 2011
Further to your query on the FCR of liquid feeding there are not a lot of published data on this and most of the conclusions stem from anecdotal evidence.
I am trying to develop a mix of yoghurt, glucose and acidifier to give my piglets as a scour reducer?
Tuesday, 15 February 2011
These products are available commercially (eg pigletsart, colostar etc) and seem to be unit, or even stockman, specific - some people swear by them, some hate them.
Does glucose break up colostrum?
Tuesday, 15 February 2011
In calves you don’t give glucose alongside milk as it clots in the abomasums therefore reducing absorption. It is not as critical in the piglet, as often, if you don’t rehydrate, the piglets will die anyway.
Can you clarify whether or not you can feed raw potatoes to pigs please, I thought that the tryptophan they contain harms them?

Tryptophan can never really harm them – it might help them sleep though! Solanin – the alkaloid poison - could reduce their growth and immunity if at high levels from green spuds however.
Young growers are also known to sometimes choke on whole potatoes so they are best chopped – but the starch source is good and so potatoes can be a good source of DE if cheap.
My water meter is giving a very high reading for water output; averaging well over 10 gallons per day per sow. I believe I have a water leak but just to make sure how much should sows be drinking per day?

The water flow through a nipple drinker for the lactating sow should approximate 1.5 to 2 litres per minute. Water intake in the dry sow varies from 9-18 litres per day and in lactation from 18 to 36 litres. Source:
I run a small pig enterprise alongside beef and sheep enterprises. Can I feed maize silage, crimped maize or crimped field beans to growing and finishing pigs? If yes, what other ingredients should I be including in the diet, to provide protein and minerals? The pigs are purebred Middle Whites.

In short you can feed any of these materials, though the feeding value of maize silage for pigs is low and it would only meet a proportion of their energy requirements, but represents an opportunity as explained below.

The feeding of purebreds and rare breed pigs is a bit experimental initially as there is uncertainty over their protein and energy requirements.
A suitable diet would contain a milled mix of field beans and cereals supplemented with minerals and vitamins. As the protein requirement of Middle Whites is likely to be lower than commercial pigs, you may find that there is no additional need to add a good quality protein source such as soya bean meal. Your nutritional advisor should be able to formulate a suitable diet, and we could help if required.

The challenge with purebreds is to control fat deposition, whilst meeting their healthy appetite for food! This can be achieved by offering some foraging material in addition to their daily concentrate allowance. Maize silage would serve this purpose, but root vegetables, such as carrots, turnips, beet etc are ideal. Not parsnips.
I have very little experience of pig production and would like some information on the possibility of finishing pigs on potatoes. I have approximately 4 acres of potatoes that have not been harvested and I am considering the possibility of letting some pigs into the field to make use of the crop. I would appreciate any advice you could give me regarding additional nutritional requirements, batch sizes, breeds, shelters and any other practical and husbandry issues.

Raw potatoes can be fed to pigs and they would happily uproot them from the field, as well as making a mess in the process!

The potatoes should not have been exposed to sunlight as the glycoalkaloids in green tubers may be toxic to pigs, though there is little research on this subject.
