“…That could reflect discomfort when the sows put their weight on an affected leg. The same phenomenon was observed in cows by Pastell et al (2008), using a scale system during milking. On the other hand, Chapinal et al (2010) found less steps per hour in lame cows over 24 h. However, these measurements were taken independently of the posture of the cow and may have been influenced by the greater time spent lying.…”

Lameness in sows has an economic impact on pig production and is a major welfare concern. The aim of the present project was to develop methods to evaluate and quantify lameness in breeding sows. Five methods to study lameness were compared between themselves and with visual gait scoring used as a reference: footprint analysis, kinematics, accelerometers, lying-tostanding transition and foot lesion observation. Fifty sows of various parities and stages of gestation were selected using visual gait scoring and distributed into three groups: lame (L), mildly lame (ML) and non-lame (NL). They were then tested using each method. Kinematics showed that L sows had a lower walking speed than NL sows (L: 0.83 6 0.04, NL: 0.96 6 0.03 m/s; P , 0.05), a shorter stride length than ML sows (L: 93.0 6 2.6, ML: 101.2 6 1.5 cm; P , 0.05) and a longer stance time than ML and NL sows (L: 0.83 6 0.03, ML: 0.70 6 0.03, NL: 0.69 6 0.02 s; P , 0.01). Accelerometer measurements revealed that L sows spent less time standing over a 24-h period (L: 6.3 6 1.3, ML: 13.7 6 2.4, NL: 14.5 6 2.4%; P , 0.01), lay down earlier after feeding (L: 33.4 6 4.6, ML: 41.7 6 3.1, NL: 48.6 6 2.9 min; P , 0.05) and tended to step more often during the hour following feeding (L: 10.1 6 2.0, ML: 6.1 6 0.5, NL: 5.4 6 0.4 step/min standing; P 5 0.06) than NL sows, with the ML sows having intermediate values. Visual observation of back posture showed that 64% of L sows had an arched back, compared with only 14% in NL sows (P 5 0.02). Finally, footprint analysis and observation of lying-to-standing transition and foot lesions were not successful in detecting significant differences between L, ML and NL sows. In conclusion, several quantitative variables obtained from kinematics and accelerometers proved to be successful in identifying reliable indicators of lameness in sows. Further work is needed to relate these indicators with causes of lameness and to develop methods that can be implemented on the farm.

“…The cows with an affected limb would transfer the load on the other three legs for a longer period, thus reducing the load on the affected limb. Pastell et al (2008) studied step force applied on a scale by sound and lame cows. The lame leg had a lower step force and a longer stance time.…”

Streszczenie. Choroby racic u krów mlecznych utrzymywanych w intensywnych systemach produkcji występują równie często jak zapalenie wymion (mastitis), choroby układu rozrodczego i zaburzenia metaboliczne. Istotne jest stałe kontrolowanie zachowań i aktywności ruchowej krów oraz opracowanie obiektywnych metod oceny ich lokomocji i wczesnego wykrywania kulawizn. Kulawizny charakteryzują się wieloczynnikową etiologią obejmującą aspekty genetyczne i technologiczne, warunki utrzymania, a także, w znacznym stopniu, żywienie, pielęgnację i higienę zwierząt. Znajomość przyczyn powstawania chorób racic i metod profilaktyki oraz umiejętność szybkiej diagnostyki i leczenia kulawizn mogą przyczynić się do skrócenia procesu chorobowego i poprawy wyników produkcyjnych stada.

“…5. In the impulse calculations, the integral was approximated to a triangle, where the value of the impulse was derived from the horse kick maximum multiplied by half its duration (Pastell et al, 2008). With a maximum force of 3115 N, the value of the integral is thus 31 ms/2 x 3115 N = 48 Ns.…”

Fittings and fixtures in horse stables may cause injuries to horses when trapped and there is a high risk of an accident to animal and handler when releasing a horse. The risk of injuries to horses and handlers must be minimised by correct structural design and appropriate choice of building material. The physical load of unprovoked and provoked horse kicks were measured in order to obtain data for the design of safe horse fittings and fixtures.To record the forces exerted by horse kicks a measuring wall and a computerised measuring system were constructed and used in single horse boxes. For reference, the characteristics of the measuring system were determined by a drop hammer test. Through regression analysis a linear relation was found between the field recorded impact values from horse kicks obtained by the measuring system and drop hammer impact values. The drop hammer method can thus be used to test fittings.Impacts recorded in the field tests were rapid, often shorter than 0.03 s and 90% had a maximum value below 1924 N. The greatest impact force and impulse caused by a horse kick were 8722 N and 131 Ns respectively, with no statistical difference between provoked and unprovoked kicks. Considering the data obtained and allowing a certain safety margin, the impact resistance of horse fixtures and fittings in single horse boxes, to be used for horses of up to 700 kg mass, should be at least equivalent to 150 Ns exerted by a horse shoe at 45°.
