Goat/sheep housing




Site Selection for a Sheep and Goat Farm 
 
Due consideration should be given to the following points in site selection for a sheep and goat farm.  Drainage: The area should be slightly sloped for effective drainage.
Wind direction: Animal houses should be partially or totally protected from the direction of strong winds depending on the wind intensity of the area.
Climatic factors: Such as temperature and rainfall. 

Sheep and Goat Facilities

Essential sheep and goat facilities differ according to the system of management and climatic conditions. In modern production systems, where large flocks of sheep or goats are raised and managed, facilities to handle sheep and goats are essential for efficient management.
Some of these facilities are:
Fences, Handling pens, Housing (house/barn – different kinds of buildings) Dipping vats/spraying area Isolation ward for sick animals Manure disposal pit (away from the house), and Equipment (feeding and watering troughs, etc.)
Fences are important not only to protect animals against predators or theft but also to isolate them from other animals. Fences could be constructed from locally available materials with considerations for cost and durability. Materials resistant against termites are most durable. Alternatively, wooden posts of treated eucalyptus could be used. Barbed wire is commonly used but can damage the skin when animals try to squeeze through an opening. Fences require regular supervision and maintenance. In some instances trees or brush may be grown and fashioned into a live fence
Handling pens Sheep and goats need to be handled, either in groups or individually, for vaccination, treatment, mating, weighing, etc. Handling
Facilities Design
In simple terms, handling facilities comprise the following: low density holding areas, high density holding areas, forcing (or crowding) area, drafting (sorting) race, and handling (working) race.
Most producers can use nearby pastures and laneways as their low density holding areas. These areas need to be secure enough to prevent escapes (particularly lambs) from one area to the next. Consider using net wire fencing with openings no larger than 15 cm by 15 cm, secured to closely spaced posts.
High-density holding areas need to be built with medium to strong fencing materials. Densities of 2 sheep in full fleece per square meter allows enough room to drive the group into the yards, while leaving space for gates to swing, and dogs to work where they are used. It is particularly important that these areas are long and narrow so that groups are easily controlled while being driven up into the forcing (crowding) race. Recommendations in Australia and New Zealand are that these high-density holding areas be no wider than 10 m. If greater capacity is needed, it is better to lengthen them, rather than making them wider.
Features of the pen

Footbath 
  • A footbath made of galvanized steel sheets or brick in cement mortar shall be provided at the entrance to the yard to protect the animals from foot-rot disease.
  • These baths may be embedded in the soil suitably.

Floor /Floor plan
  • The flooring may be either of moorum or of strong wooden battens and, where the rainfall is quite heavy; the latter type of flooring may be preferred.
  • In the case of wooden-batten flooring, the width of each plank shall vary from 7.5 to 10.0 cm and the thickness between 2.5 cm and 4.0 cm.
  • The sides of the planks shall be well rounded and the clearance between two planks shall range between 1.0 cm and 1.5 cm to facilitate the disposal of dung and urine.
  • The wooden-batten flooring shall be constructed at a height of at least one metre above the ground level.
  • In this case, a suitable ramp or steps of wooden planks shall be provided.
  • In the case of moorum flooring, a plinth wall between 15 cm and 30 cm in height shall be provided.
  • For the shearing and store room and shepherd's house, the flooring may be of moorum or brick in cement mortar, and the floor shall be levelled properly.
Roof

·        The roof is important as it protects animals against the sun and rain. The under-surface of the roof should remain cool and watertight.
·        To ensure adequate ventilation, the height of the roof and the design should be considered. A high roof encourages air movement but is more likely to be damaged by strong winds.  In some cases a design with a chimney or roof vent could be useful to assist ventilation and remove ammonia that could easily accumulate.
·         The following materials are used for roof construction in different locations: Iron sheet  Grass/bushes Wood  Stone/brick  Earth  .The majority of houses have roofing made of grass/bushes.

Gate
  • Each shed may be provided with one or more gates either on the long or broad sides of the sheds depending upon the dimensions of the shed.
  • The dimensions of each gate may be 0.8 m broad and one metre high. The gate leaf and frame may be made of wooden battens. It shall fit the entrance closely.
Elevated floor
  • Its initial investment is high.
  • In the wooden floor sheds, in a distance of 3m from the floor, the animals are reared.
  • This requires less labour and more irrigation land for the fodder production.
  • The elevated sheds will be clean and urine and dung will be collected in the floor and periodical removing is required once in six months.

Walls
·        In warm climates walls are partially open to allow movement of air through the house. In some cases, however, complete walling is needed to keep out predators.  Ventilation is important to remove heat, moisture and pollutants so that animals stay cool, dry and clean.
·        Outer walls protect the animals from external influences while separation walls within the house prevent mixing among the animals.
·        Attention needs to be given to construction of pens within the house. Pens serve as a means of controlling animals and for management purposes, such as controlling breeding. Areas for lambing/kidding and isolation of sick animals should be included.
·         It is always wise to keep in mind the possibility of expansion when building houses for sheep and goats.
·        An appropriate flock development plan has to be made to anticipate future construction needs.


Different sheds in an organized sheep and goat farm
The sheds of the following types are required for housing the animals,
  • General flock shed (Ewe / Doe shed) 
  • Ram or buck shed 
  • Lambing or kidding shed 
  • Lamb or kid shed
  • Sick animal shed
  • Shearing and storeroom
  • Attendant's room
 
General flock shed (Ewe / Doe shed) 
  • The flock shed shall be used for housing ewes or does kept for breeding purpose.
  • The shed shall be 15m (l) x 4m (w) x 3 m (h) and can accommodate not more than 60 ewes or does.
  • The shed should be three metre high and should have brick-on-edge floor.
  • In low lying and heavy rainfall areas, the floors should preferably be elevated and in temperate regions they may be made of strong wood.
Ram / buck shed
  • Rams or bucks kept for breeding purpose are housed individually in these sheds. Alternatively, wooden partitions can be raised in bigger shed to partition in to stalls.
  • The dimension is of 4m (l) ×2.5m (w) ×3m (h) and can accommodate about 3 rams/ bucks.
  • The shed shall be partitioned lengthwise to form three equal compartments.
  • The partition between each shed should not exceed one metre.
  • The partitions may be either of wooden planks or half-cut ballis.
  • The partition shall be not more than one metre high from the floor.
Lambing / kidding shed
  • These sheds shall be used as maternity rooms for pregnant ewe or doe and are housed individually in these sheds.
  • The shed shall be 1.5m(l)×1.2m(w)×3.0m(h), a manger for holding feed and hay and a bucket for keeping water shall be provided in the shed.
  • These sheds shall be made draught free.
  • In cold climates some warming device, like a room heater shall be fixed in maternity pens, so that new borns are protected from cold during winter.

Additional facilities 

Dipping vat

Mobile dip vats have replaced the conventional dip vats made of concrete. Several years of effort to introduce dipping vats into tropical countries have had limited success, the major problem being maintaining the vats. Mobile dip vats made of plastic are meant to overcome the shortcomings of conventional, permanently placed dip vats. The size of plastic, mobile dip vats could vary according to flock sizes.
Feeding trough and hay racks -Feed troughs for concentrate and hay racks for forage feeding are required where these practices are conducted. The size of racks and troughs is determined by the body size of sheep and goats and by animal numbers. Approximately 30 to 40 cm per animal space is the minimum. Movable troughs are usually 2 to 4 m long. Fodder should not be put on the ground for sheep and goats. A feeding rack can be made from wood or other locally available material such as bamboo. The rack should be high enough to prevent adult sheep and goats from putting their heads in it and from jumping into the rack. The bottom should be above normal head height. It should be noted that the feeding behavior of goats is different from that of sheep and a barrier is needed to prevent animals from jumping into the trough. In a system called ‘tombstone or keyhole barrier’, each animal puts its head through an individual wooden barrier to eat without being able to push its body into the trough. Suggested dimensions for a concentrate trough are a width of 30 cm with a depth of 15 cm, with the trough standing on 15 cm legs. In general, troughs placed directly on the ground are not desirable because mud or soil can get into the trough, and sheep and goats are tempted to put their feet in. When only a limited amount of supplementary feed is given, it is essential that the trough is long enough to allow all animals to eat at once. Some troughs are fitted with a yoke to restrain animals during the short period of supplementary feeding. Such structures allow individual recording of the amount of concentrate consumed by each animal.

Farmstead Planning

The farmstead forms the nucleus of the farm operation where a wide range of farming activities take place. It normally includes the dwelling, animal shelters, storage structures, equipment shed, workshop and other structures. A carefully organised farmstead plan should provide an arrangement of buildings and facilities that allows adequate space for convenient and efficient operation of all activities, while at the same time protecting the environment from such undersirable effects as odours, dust, noise, dies and heavy traffic. A wide range of factors, should be considered when planning the arrangement of buildings and services at the farmstead.
Although the immediate objective of these plans may be the inclusion of a new building in an existing farmstead, provision should be made for future expansion and replacement of buildings. In this way a poorly laid out farmstead can be improved over the long term.
Factors to consider in farmstead planning
In planning a farmstead one has to consider number of factors; such as:
Good drainage, both surface and sub-surface, provides a dry farm courtyard and a stable foundation for buildings. A gentle slope across the site facilitates drainage, but a pronounced slope may make it difficult to site larger structures without undertaking extensive earth-moving work. Adequate space should be provided to allow for maneuvering vehicles around the buildings and for future expansion of the farm operation.
Air movement is essential for cross ventilation, but excessive wind can damage buildings. Since wind will carry odours and noise, livestock buildings should be placed downwind from the family living area and neighbouring homes. Undesirable winds can be diverted and reduced by hedges and trees or fences with open construction. Solar radiation may adversely affect the environment within buildings. An orientation close to an east-west axis is generally recommended in the tropics.
An adequate supply of clean water is essential on any farm. When planning buildings for an expanded livestock/crop production, the volume of the water supply both for present and future needs must be assessed. The water source can be a well, river, dam or spring. Ponds can be used but must be located where they can collect enough runoff.  Where applicable, the supply of pipe in a good building layout should be as short as possible. Similarly, the length of electric, gas and telephone lines should be kept to a minimum.
The safety of people and animals from fire and accident hazards should be part of the planning considerations. Children especially, must be protected from the many dangers at a farmstead. It is often desirable to arrange for some privacy in the family living area by screening off the garden, outdoor meeting-resting places, verandah and play area.
Measures should be taken for security from theft and vandalism. This includes an arrangement of buildings so that the farm court and the access driveway can be observed at all times, especially from the house. A neat and attractive farmstead is desirable and much can be achieved toward this end, at low cost, if the appearance is considered in the planning, and effective landscaping is utilized.
Services
Road Access — Ready access to roads and highways is important. Don't locate the farmstead too far from a public road, or you'll have to build and maintain an all-weather road. The house should be the first building seen (orapproached) when entering the farmstead for both appearance and traffic control. Regardless of where the farmstead is situated, choose the site for the house first and locate all other buildings in relation to it.
You might consider having two entrances to the farmstead, one to the house and another to the main activity area. Such an arrangement reduces traffic, dust and noise around the house, but uninvited visitors are more difficult to detect.
If you install a gate at the entrance, place it at least 12 to 18 m from the road so vehicles have room to stop while the gate is being opened. Build the drive about 5 m wide with at least 2 m of additional clearance on each side; the extra width the extra width allows for large overhanging equipment and snow storage. Drains along the drive can be within this 2 m.
Avoid blind exits
Plan parking area to avoid traffic congestion and road blocks
Electricity
Electricity and gas — Electricity is an important source of power. Plan installation carefully to ensure adequate supplies are available when and where you need them.
Telephones — The telephone is an important tool for most farm businesses. Mobile phones could also save you valuable time in your operation.
Fire prevention
Prevent fires, by having adequate wiring, efficient lightning protection, and proper storage of fuels. Also, avoid causes of spontaneous combustion and practice good housekeeping.
To reduce the risk of fire:
Use fire-resistant building materials.
Install water hydrants near to building areas.
chemical fire extinguishers
adequate space between buildings
Security can be difficult. Farms are vulnerable to theft, arson and trespassing. A clear view from the house of the farm discourages prowlers. Yard lights will help keep away thieves. Strategically placed gates which can be locked can stop vehicular access at night or when you are away and may discourage unwanted intrusions.

Zone Planning
Zone planning can be a useful tool, but it is most effective when planning a new farmstead. The farmstead is divided into zones 10 to 30 metres wide by concentric circles as shown in Figure.



 Zone planning in four zones.
Zone 1 at the centre of the farmstead is for family living, and should be protected from odour, dust, flies, etc. In Zone 2 clean, dry and quiet activities, such as implement sheds and small storage structures can be placed. In Zone 3 larger grain stores, feed stores and small animal units are placed, whereas large-scale animal production is in Zone 4 and beyond.
The advantage of zone planning is that it provides space for present farm operations, future expansion and a good living environment. However, in many cultures the livestock has traditionally been placed at the centre of the farmstead. Thus the zone concept runs counter to tradition and may not be desirable.
The layouts below are another form of farmstead planning that can be useful.
Zone 1 family house/ administrative building.
Zone 2 machinery/tools implements
Zone 3 harvest storage (pack house/ storage)
Zone 4 livestock buildings
