“…Differences in BMD are also physiologically related to muscular activity in humans (Taaffe et al., 1994; Tsuji et al., 1995), dogs (Puustjarvi et al., 1991) and horses (Cornelissen et al., 1999; Shea Porr et al., 2000). Likewise, variations in bone mineralization have been reported in relation to diet in dogs (Lauten et al., 2002), horses (Hoffman et al., 1999;Shea Porr et al., 2000) and beef cattle (Shupe et al., 1988; Williams et al., 1990; Beighle et al., 1995, 1997; Motsei and Beighle, 2006). Lastly, the stages of lactation and parity have been reported to affect BMD in both mares (Glade, 1993) and dairy cows (Beighle, 1999; Keene et al., 2004).…”

The metacarpal bone mineral density of 136 healthy feedlot beef cattle of four different breeds (Charolaise, Limousine, Irish Crossbreed and Slovakian Crossbreed) raised and fed on standard conditions was measured by means of a dual-energy X-ray absorptiometry technique in an ex vivo study design. The average reference values (mean ± SD) of bone mineral density (BMD) for animals aged between 12 and 22 months and weighing between 236 and 546 kg have been reported and the effects of (i) breed, (ii) gender, (iii) age and (iv) body weight on bone mineral density have been considered. A significant difference (i) among different breeds and (ii) between genders resulted, whereas a high correlation between bone density and (iii) age and (iv) body weight was detected within the same breed and gender, with body weight being the most important factor affecting BMD. A modern new technological insight into the study of bovine bone physio-pathology is proposed.

“…A alta concentração de cálcio verificada em algumas rações pode ter participação no aumento da incidência de doenças osteoarticulares do desenvolvimento, como osteocondrose, osteocondrites, displasias de cotovelo e coxofemoral, constatadas na rotina clínica no Brasil por Pinto (2002). Schoenmakers et al (1999) e Lauten et al (2002), ao trabalharem respectivamente, com teores de cálcio de 3,1% e 2,7% na matéria seca, inferiores aos encontrados em alguns produtos na presente amostragem, reproduziram distúrbios osteoarticulares relacionados ao crescimento em cães de raças grandes. Hazewinkel et al (1991) constataram que dietas com 3,3% de Ca, independentemente de sua relação com o P, promoveram maior taxa de retenção do Ca em cães de raças grandes em fase de crescimento.…”

“…Hazewinkel et al (1991) constataram que dietas com 3,3% de Ca, independentemente de sua relação com o P, promoveram maior taxa de retenção do Ca em cães de raças grandes em fase de crescimento. As concentrações de Ca e P nas dietas de filhotes até seis meses de idade refletem-se rápida e diretamente sobre o seu conteúdo mineral ósseo, motivo pelo qual as doenças esqueléticas do desenvolvimento manifestam-se com maior freqüência no início do crescimento dos cães (Lauten et al, 2002).…”

Avaliaram-se 49 marcas de rações para cães adultos e filhotes comercializadas em Jaboticabal-SP. Os alimentos foram divididos em três segmentos: econômico, standard e super-premium. Nessa ordem, as rações para cães adultos apresentaram, em média, 16,9%, 20,9% e 27,8% de proteína, 9,7%, 10,5% e 15% de gordura, 6,4%, 2,9% e 1,1% de fibra e 1,9%, 1,9% e 1,4% de Ca. Para filhotes, os produtos standard e super-premium apresentaram, respectivamente, 26,1% e 31,0% de proteína, 10,8% e 15,2% de gordura, 2,6% e 2,4% de fibra, 2,1% e 1,7% de Ca e 1,6% e 1,3% de P. A porcentagem de rações cujos teores nutricionais declarados no rótulo não estavam de acordo com os encontrados nas análises de laboratório foi, para os produtos super-premium para filhotes, 80,0% para o Ca e 60,0% para a gordura; para os produtos standard para filhotes, 28,6% para proteína e 57,2% para o cálcio; para os produtos econômicos para cães adultos, 44,0% para a fibra e 33,0% para a proteína; para os produtos standard para cães adultos de 33,0% para a gordura e 50,0% para o Ca; e para os produtos super-premium para cães adultos, 50,0% para o cálcio e 33,0% para a gordura. Foram encontradas inadequações nutricionais em produtos, como teores insuficientes de proteína e altas concentrações de fibra, cálcio e fósforo.

“…When Foxhound crossbreeds were fed a P supply above the previously published recommended allowance (18) , the animals developed no clinical or subclinical symptoms (2) . Lauten et al did not state their clinical findings clearly enough to evaluate their results in this context (8) . The hypothesis that DOD in growing dogs is related to the co-factor P supply was reinforced by the results of a study of P deficiency in growing Beagles and Foxhound crossbreeds (19) .…”

Factors that modify the effect of excess calcium on skeletal development in puppies

Developmental skeletal problems are often connected to mistakes in feeding, i.e. a deficiency or excess supply of nutrients, especially minerals. The energy consumption, the resulting growth intensity and the breed of animals are also known as factors that influence developmental orthopaedic diseases. In most clinical trials, excess Ca was connected to alterations in normal, healthy skeletal development, which led to severe clinical symptoms in some dogs, subclinical changes in the radiographic or histological examinations in other animals, or even no observable symptoms. These results correspond to practical experience in the field of clinical nutrition consultation, since excess Ca has been shown to have various impacts in growing dogs. The present review of results published in the literature and from my own trials led to the hypothesis that P is an important co-factor that can alleviate or aggravate the development of skeletal problems in growing dogs.
