Note the swollen cheeks and drooling of saliva in this Cheviot ewe. The mandibular canine is incisiform and is followed by a long diastema. In many herbivore species, the forces of almost continuous grazing or rumination leads to dental attrition.

The dental formula is incisors 3/3, canine 1/1, premolars 4/4, molars 2/3. Samples collected at necropsy from the rumen of normal sheep have much shorter fibre length than samples from sheep with molar dentition problems illustrating the problems caused by poor mastication of fibrous feeds.

NADIS hopes that you have found the information in the article useful. 19 months All sheep showing as 2-tooth, one rising 4-tooth. Excessive premolar and molar teeth wear, leading to malocclusion and poor mastication of fibrous food, is a major cause of weight loss and poor condition in older sheep. Dentition pertains to the development of teeth and their arrangement in the mouth.In particular, it is the characteristic arrangement, kind, and number of teeth in a given species at a given age. Examination of incisor teeth alignment is performed by running an index finger along the dental pad, with the sheep's mouth closed and the head held in the normal resting position. I - 0/4 C - 0/0 P - 3/3 M - 0/0 = 10 x 2 = 32. b) Permanent teeth. The maxillary arcade or upper jaw is listed over the mandibular arcadeor lower jaw. a) Temporary teeth. The temporary incisor teeth erupt sequentially at approximately weekly intervals from birth. A dog generally has full dentition by six to seven months of age. Premature loss of incisor teeth is a major problem that leads to early culling because affected sheep are unable to bite short pasture leading to malnutrition, poor production and weight loss particularly on marginal grazing and hill pastures. Thus the dental formula for the sheep is: It indicates that in the upper right (or left) half of the jaw there are no incisors or canines (i.e. The first number in each formula represents how many sets of teeth are on the upper jaw; the second number indicates how many sets of teeth are on the lower jaw.

Fig 1: Correct dentition is essential for sheep grazing rough pasture. Sheep with severe teeth lesions often drop pelleted feed when eating and may raise their head while masticating to assist movement of food over the dorsum of the tongue and into the pharynx. Premature loss of incisor teeth (broken mouth) is a major problem leading to early involuntary culling because affected sheep are unable to bite off short and/or rough pasture leading to malnutrition, poor production and weight loss.

The permanent central pair of incisors erupt at 15 months and are in wear by 18 months; the other permanent incisors follow sequentially at six months' intervals. Note the swollen cheeks and drooling of saliva in this Cheviot ewe. The mandibular canine is incisiform and is followed by a long diastema. In many herbivore species, the forces of almost continuous grazing or rumination leads to dental attrition.

The dental formula is incisors 3/3, canine 1/1, premolars 4/4, molars 2/3. Samples collected at necropsy from the rumen of normal sheep have much shorter fibre length than samples from sheep with molar dentition problems illustrating the problems caused by poor mastication of fibrous feeds.

There are no recognised control measures for this sporadic condition. There is no treatment and affected sheep should be culled although their body condition can be improved by 1.5 to 2 units of condition score following generous concentrate feeding (up to 1.5 kg daily) over a 10 to 12 week period which would command a much better slaughter price. . The lower incisors project forward and are joined by modified canines that emulate the incisors. Unopposed wear has resulted in overgrowth and a stepped mouth in this sheep.

For example, the 0/4 means that sheep… Sheep with such incisor teeth mal-alignment with the dental pad should be culled as fat lambs but it is surprising how many sheep are kept as breeding stock despite such teeth problems. Cheek teeth problems tend to be of greater significance than incisor teeth loss due to loss of their grinding function of fibrous feedstuffs. The three temporary premolars erupt within two to six weeks. All Rights Reserved. Almost all mammals have four kinds of teeth: incisors; canines; premolars; molars; Teeth numbers and form have adapted to different feeding methods.
