Food for mums and babies: nutrition at lambing

Lambs double in size in the last month in the ewe, which is a real challenge to the ewe to keep up with this as well as the additional situation of less room inside! So feeding more frequently, twice or even three times a day, will regulate intake better and make it more effective. Insufficient food can lead to dead lambs, or ewes, or twin lamb disease, poor quality colostrum and lower milk production. Too much concentrated food can reduce the pH in the rumen, so quality is as important as quantity, and forage is key, with concentrates as a supplement. Added yeast has been shown to be useful in improving colostrum quality and reduces the build-up of lactic acid in the rumen, which helps increase milk yield and quality.

Is it all in the soil?

We know that the correct minerals and trace elements are essential for good health of sheep, goats and alpacas – but how do we know what to do about this?

Firstly we need soil tests. These are easier than you might think – you should take about 30 samples diagonally across the field, mix in a bucket to get a representative sample of the whole field then put some in a bag to post off for a soil test. Ideally, soil testing should be done every two years, as rain, grazing and hay or silage cutting will all affect the soil balance.

The Post Truth Conference Season – good ideas and random thoughts …

There is a fashion in business and politics at present to look for strong leaders, perhaps always and not just at present …. I am a very strong leader when I wish to influence my sheep and am carrying a bucket of food – although at some times of the year my rams are less keen to follow me than to seek the ewes. Elsewhere, I am less influential!

There is also a need for innovation, which seems to be a very human trait. Necessity may be the parent of invention, and of course we have some of that at present. Also of course, the cross-country and Telemark skiing mantra, “Free the heels, free the mind” is interesting – putting things into a different context will lead to new thinking.

A difficult year?

We all also know that each year brings its own challenges, particularly the weather – too hot, too cold, too wet, too dry, or mainly too much of these at a time! My own experience this year has not been easy and I will share some of it … firstly the lambing was good, with two live lambs per ewe. Some were rejected, so we ended up with two bottle-fed babies, which survived, even the ewe born weighing 0.5kg. They were born in March-April and all went on well to weaning and then to first shear in early July, when the shearer remarked how well they looked. However, we had problems with a couple of ewes, two with mastitis and one sudden death, for no apparent reason, so it is probably that some of the apparently healthy lambs were not getting all the nourishment they needed. So fairly early weaning and shearing were additional stresses.

Sheep are proverbial amongst the farming community for having a strong death-wish! Indeed it is even said that no Blue-faced Leicester should be sold without an accompanying spade with which to bury it …

(We should point out that it is illegal to bury dead stock mostly, but this saying pre-dates current requirements!)

The main issue for sheep is that, although they have relatively few predators once past being tiny lambs, apart from out-of-control dogs, they are quite inclined to get both diseases and parasites, particularly if intensively farmed on land which has had sheep for many years. This is of course exacerbated by their flocking instinct, so it’s a bit like primary schools as great incubators of infection. Older animals can carry a level of parasites without problems if they are otherwise healthy, and have also been observed to self medicate from suitable herbs or ivy, whenever they get the chance, and to avoid plants poisonous to them, such as bracken or ragwort.

Sue's lambs had their first hair-cut this week

The lambs grow wool quite quickly and it is the finest and softest they will produce (even from Nathalie!).

So here they are last week:

Sheep and Copper

In my (Sue's) experience, the biggest single factor in health of sheep is the correct balance of minerals, which permits their immune systems to function optimally. Thus for example, most sheep should not have much copper, though all need some, with downland and Texel sheep being particularly susceptible to copper poisoning, fine-woolled sheep intermediate, while Gotlands and Finnsheep are more tolerant than other breeds and indeed need a greater amount.

This is why it is important never to feed sheep with pig or poultry feed, which contains too much copper. My sheep broke into the feed store and gorged themselves on pig food once and the greediest had the worst hangovers – luckily a vitamin injection was sufficient to get them back into a state of normality (as far as Gotlands are ever normal …).

Sheepskins

Though not everyone keeps sheep for meat, those who do will be aware that there are by-products from the abattoir which in most cases do not come back to the producer. The most obvious are the skins, along with horns and offal usually. Abattoirs sell these products elsewhere into the relevant trade but is possible to get skins back for tanning.

There are a few areas of red tape that have to be considered when sending sheepskins to the tannery. This is mainly due to the foot-and-mouth outbreak in 2001, along with strict rules regarding movement, skins were no longer permitted back on the holding that the animal came from. However, since then the Animal By-Product Regulations came into effect which allows individuals to collect fresh skins from the abattoir. In most cases an AB117 form needs to be complete to ensure that your skins are returned to be tanned.

Mules and Mashams

Mules and Half Breds are the most common type of sheep in the country and make up a large majority of our commercial flocks. They are good mothers and can carry twins, triplets or even quads! They produce fast-growing, lively lambs which makes them perfect for the commercial meat market. As well as this, some types of Mule also produce high-quality fleeces due to the rams that have been used as sires.

Fly strike

The thought of flystrike can send a chill through any shepherd; though no illness or disease in sheep is pleasant, this is one of the worst. After a mild, very wet winter, the numbers of fly larvae around will be greater than usual, so it will be doubly important to watch out for strike and deal with it without risking compromise to the health of the sheep or the potential to use the wool.

The economic cost of flies is estimated to reduce milk yields by 0.5 litres per cow per day and growth rates by 0.3kg per head per day in cattle, which can easily be extrapolated to sheep - it's not just the damage to an animal which has been struck, but the irritation which distracts the whole flock from getting on with eating and growing.
