12、ical Committee B/549. It supersedes BS 5502-40:1990 which is withdrawn. This revision takes into account the new regulations on the welfare of farmed animals and current advances in livestock handling research.BS 5502 has been structured into the following broad subject areas: Part 0: Introduction a
13、nd consolidated index; Parts 10 to 19: Reference information and legislation; Parts 20 to 39: General design; Parts 40 to 59: Livestock buildings; Parts 60 to 79: Crop buildings; Parts 80 to 99: Ancillary buildings.More specifically, reference information and legislation is covered in: Part 11: Guid
14、e to regulations and sources of information.A more detailed description of the structure of BS 5502 is given in Part 0.The object of the structure is to allow subject areas to be broadly characterized, and related subject matter, whether in the form of recommendations, guidance or supporting data, t
15、o be rationalized and brought together. It will also allow sufficient flexibility to enable BS 5502 to be expanded and developed in a logical way in the future.It has been assumed in the drafting of this British Standard that the execution of its provisions is entrusted to appropriately qualified an
16、d experienced people, for whose guidance it has been prepared.This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application.Compliance with a British Standard does not of itself confer immunity from legal obligations.Summar

25、nt Codes of recommendations applying in England, Scotland, Wales and Northern Ireland for the welfare of cattle, and the various statutory regulations, including the Welfare of Farmed Animals Regulations 1, 2, 3, 4 that apply in the various countries of the UK. BS 5502-11 provides guidance and furth
26、er information regarding legislative requirements.4.1 The welfare of cattle should be assessed in the context of the guidelines known as the “Five Freedoms” as follows.a) Freedom from hunger and thirst by ready access to fresh water and a diet to maintain full health and vigour.b) Freedom from disco
27、mfort by providing an appropriate environment including shelter and a comfortable resting area.c) Freedom from pain, injury or disease by prevention or rapid diagnosis and treatment.d) Freedom to express normal behaviour by providing sufficient space, proper facilities and company of the animals own
28、 kind.e) Freedom from fear and distress by ensuring conditions and treatment which avoid mental suffering.4.2 All buildings should be designed, constructed and maintained so as to avoid discomfort, distress or injury to cattle. All fittings and surfaces accessible to livestock should not be harmful
29、to livestock and should not have sharp edges or projections and fittings should be arranged so as to avoid injury. All buildings should be capable of being cleaned and disinfected.4.3 Cows, replacement heifers or calves should not be kept on a fully slatted, perforated or mesh floor. A solid floor a
30、rea incorporating straw or other suitable bedding should be provided to ensure comfort and to reduce the risk of injury to the udders and hocks of all cattle.4.4 In accommodation for cows, it is essential to provide separate solid floored bedded pens for use at calving time, and a solid floored cree
31、p area with bedding should be available for the calves, where cows with calves at foot are grouped together. Calves should have access to a well-bedded and dry-lying area.4.5 Cattle housed on slats with rubberized or cushioned surfaces should have access to adequate areas of hard surfacing to provid
32、e foot abrasion.4.6 All yards, pens and passageways should be kept in good condition.5 Design and construction5.1 DesignThe building or structure should be designed and constructed in accordance with the general principles and recommendations given in BS 5502-20, BS 5502-21, BS 5502-22, BS 5502-23 a
33、nd BS 5502-25.Pens, isolation boxes and other accommodation for the housing of fractious animals should be robust in construction and have safeguards for the protection and escape of stockpersons. Particular attention should be paid to the housing of bulls (see 10.5 and 10.6).5.2 OccupancyThe types
34、and ages of the cattle to be housed, and periods during which the various parts of the building or buildings are subject to human occupation should be taken into account in the design in accordance with BS 5502-22.BS 5502-40:2005 BSI 16 September 200535.3 General construction of buildingsAll surface
35、s and fittings that could come into contact with cattle should be free from projections, edges or perforations that could cause damage, pain or injury to cattle.5.4 Floors5.4.1 GeneralFloors, to which stock have access, should have a slip resistant surface. However, this should not be abrasive nor a
36、llow moisture to accumulate so creating a risk of ice patches.5.4.2 New concrete floorsTo provide slip resistance for cattle walking in all directions, and to eliminate the risk of high pressures on the hoof, new concrete floors should be designed with grooves either in a pattern of regular hexagons
37、 or in parallel lines.NOTE A pattern of regular hexagons on flooring is supported by research carried out by CIGR as reported in The design of dairy cow housing 5.The hexagonal pattern should consist of regular hexagons with (46 4) mm sides separated by grooves (10 1) mm wide and a minimum 6 mm deep
38、 as shown in Figure 1.The parallel lines should be spaced (40 4) mm between centres, with grooves (10 1) mm wide and a minimum 6 mm deep as shown in Figure 2. Where the direction of cattle movement is known, parallel grooves should be used at right angles to the movement of the cattle.Dimensions in

40、 centres, with grooves (10 1) mm wide and a minimum 6 mm deep as shown in Figure 2.The square pattern should consist of regular diamonds or squares with (40 4) mm sides separated by grooves (10 1) mm wide and a minimum 6 mm deep as shown in Figure 3. The use of diamond cutters is recommended to avoi
41、d aggregate becoming exposed and risking damage to feet.NOTE Square patterned grooves on concrete floors are less preferable as they are not as effective in preventing high pressure on the animals hoofs.Dimensions in millimetresKey1 Direction of cattle movementFigure 2 Concrete floor with parallel g

43、ned in accordance with BS 5502-51.5.5 Walls and roof5.5.1 Walls for certain types of cattle buildings (e.g. strawed yards) might not need a damp-proof membrane and consequently, their design should be influenced by: a) whether manure can accumulate against them (for further guidance on the design, s
44、ee BS 5502-22); andb) whether they will be subject to impact from stock or mechanical handling equipment. Walls should provide adequate draught protection at stock level.5.5.2 Cladding above the side-walls should be such as to exclude the worst effects of wind, rain and snow, whilst allowing for the
45、 optimum ventilation (see Table 1).Table 1 Optimum environmental conditions for cattleDimensions in millimetresFigure 3 Concrete floor with square patternStock Temperature range Maximum air speed at stock level in winterVentilation rate per kilogram liveweightC m/s m3/h/kgCalves 7 to 30 0.25 0.38 to

Housed stock, however, have less opportunity to choose a location suitable to their needs. Th
49、e overwhelming need is for good ventilation rather than warm conditions. However, draughts and wet conditions need to be avoided.The energy balance of the animal is affected by temperature, air speed, relative humidity, wetness of animal coat and of lying surfaces, feed intake, and the availability of dry bedding. Dairy cows have a thermoneutral zone (a comfort zone) within which they work best. At either end of this comfort zone are critical temperatures at which t
