Mareks disease in Chickens

Marek's disease

The virus responsible for Marek's disease is thought to be responsible for greater mortality in chickens than any other disease. Every flock, except for those maintained under strict pathogen-free conditions, can be assumed to be infected. Flocks that do not show any symptoms may still be infected. Stress may weaken the immune systems and result in an outbreak of this disease. Although symptoms may not be apparent, there may be a reduced growth rate and a decrease in egg production.

The virus is concentrated in the feather follicles and shed in sloughed skin and feather cells. It has a long survival time and viable virus can be isolated from houses that have not been occupied for many months. Transmission is by aerosols containing infected dust. Younger birds are most susceptible to infection.

There is no treatment for Marek's disease. The main method of control is by vaccination of day-old chickens as a subcutaneous injection. Results are improved by strict sanitation to reduce or delay exposure and also by breeding for genetic resistance.

Marek's disease may produce a variety of clinical responses: visceral, neural, ocular, skin or combinations of these.

VisceralMarek's of the visceral type is characterized by widespread involvement with lesions commonly seen in gonads, liver, spleen, kidney and occasionally heart, lungs and muscles. The disease is often acute, with apparently healthy birds dying very rapidly with massive internal tumours.
NeuralThe neural type is characterised by progressive paralysis of the wings, legs and neck. Loss of body weight, anaemia, laboured breathing and diarrhoea are common symptoms.
Ocular

Ocular leukosis (gray-eye) is usually seen in early maturity. Morbidity and mortality are usually low but may approach twenty-five percent in some flocks. It is characterized by the spotty depigmentation or diffuse graying of the iris in the eye. The pupil develops an irregular shape and fails to react to light. Emaciation diarrhoea and death follow.

SkinSkin leukosis produces the most severe losses in intensively reared broilers, as a result of carcasses being condemned at the processing stage. Enlargement of the feather follicles due to accumulations of lymphocytes is the typical lesion. This is potentially the most infective version of Marek's because it is produced around the feather follicles and is shed with the skin particles and with feathers.

Wax

Wax
Two sauspans - tea strainers - one to other while melting. Alum Or ss
pans
Layer of rain water - help settle detritus heat gently stir
Powder wax dye
Pour into moulds / tubs with tapered sides. Water again to grab waste
& then tip out.
Dust , pollen, propolis, other debris.
Be patient!
Solar wax extractor - base sheet aluminum/wooden frame plus double
glazed top. Wax runs down to collect at bottom of slope. Angled
towards sun.

Wax discolueres with constant heat - choc colour. Have drip tray in
shade!

Candle moulds.

Latex from modle shop painted on - use for up to 10 then deteriate.

Glass mould - very hot tea towelk wrap round mould - should come out.

Beware purchased moulds - may have bee made for parafin wax . Bee's
wax needs thicket wick. Red: zinc wick from Thornes.

Silicon spray in mould or Pyrex bowl & washing up liquid. Check bowl
is totally smooth & fault free. One drop of inscrnted wu liquid - rub
with finger around surface until dry.

Or stainless steel bowl - no lubrication needed.

Silicon white moulds best. Rubberbnd around split but needs surround
cut from plastic bottle thereby making stand for bottim of wick to
stand free. Top - use peg to hold wick square.

Use model putti or blutac to seal bottom of wick hole.

Use pet food tin - form spout with pliers and fix handle to interior

Flatten wick at bottom of mould to reduce leakage.

Candle wick is plaited not twisted like string so burns better.

Or dip candle wick in hot was before placing in roll or candle mould.
Stifness helps formation.

Leave 20 mind plus in mould before unwrap.

Reminder regarding the rules about pruning trees within a CONSERVATION AREA - Langford and Ulting Parish's

Reminder 
regarding the rules about pruning trees within a CONSERVATION AREA 
Langford and Ulting Parish's

In a Conservation Area, any works to trees measuring 75mm or over diameter at 1.5m from the ground require 6 weeks prior notification to us before they are carried out, we would then consult the Parish/Town council concerned for their comments.

Rules regarding trees and development depend largely on what conditions have been applied to the planning permission.  If there are trees on site to be retained we always refer developers to BS5837:2005 'Trees in Relation to Construction - Recommendations' which is the current British standard they are required to follow.  In addition to this, you should know that Planning permission over-rides tree protection by TPO or conservation area.  Developers are allowed to remove or prune any tree that is in the way of them carrying out works that have planning permission.

Woodland at a 250 Year peak due to tax breaks

British woodland has returned to the levels of the 1750s with tree cover having more than doubled since the end of the First World War, a United Nations report has shown.

 

Woodland in Britain now stands at 11,200 square miles, 11.8% of the total land area.

 

The growth, attributed in part to the boom because of tax breaks, could even reach the 15% of woodland recorded in England by the Doomsday Book in 1086!
