“…It is presently unknown to which extent the alkalinizing or acidifying properties of food influence the incidence or severity of DOD in mammals. In poultry, dietary induced metabolic acidosis is associated with an increase in the incidence of tibial dyschondroplasia, and metabolic alkalosis with a decrease [74].…”

“…The incidence of developmental orthopedic disease (DOD) in several animal species is related to rapid growth which is influenced by nutritional factors [71][72][73][74]. For example, one of the major factors associated with a high incidence of DOD in giant dogs is a high dietary intake of calcium [75][76][77][78].…”

In domestic animals, acid-base balance may be influenced by nutrition. The major research effort in this area has been made on the prevention of hypocalcemic postparturient paresis in dairy cows. This disorder is caused by the sudden increase of calcium secretion into the colostrum. The manipulation of the dietary cation-anion difference makes it possible to maintain the cows in metabolic acidosis during the critical period that precedes calving, presumably via a mechanism that involves the strong ion difference in the extracellular fluid. As a consequence the mobilization of calcium is enhanced and the incidence of the disorder is decreased. Conversely, a dietary induced metabolic alkalosis leads to a more severe degree of hypocalcemia and the incidence of the disease is increased. The underlying mechanisms of the prevention are only partially understood. Nevertheless, this preventive method is already widely applied in practice. Nutrition effects on acid-base balance also influence growth and food intake in higher vertebrates and fish. As a consequence, the incidence of developmental orthopedic diseases in fast-growing domestic animal species may be affected. Also, the bone mineral content of athletic horses may be influenced by dietary induced modification of the acid-base status. The mineral loss due to metabolic acidosis may lead to an increase in the incidence of stress fractures. This overview should give insight into relevant aspects of nutrition and acid-base balance in domestic animal species.

“…Rapid growth has been described as one of the main contributing factors predisposing to the development of osteochondrosis (Ekman & Carlson 1998 ; Olsson & Reiland 1977 ; Reiland 1977 ). Osteochondrosis has been described in pigs (Grøndalen 1974 ), dogs (Trostel, McLaughlin & Pool 2002 ), newborn lambs (Corbellini et al 1991 ), poultry (Whitehead 1997 ), turkeys (Poulos 1977 ), horses (Jeffcott 1991 ), cattle (Trostle et al 1998 ), cats (Ralphs 2005 ) and rats (Kato & Onodera 1984 ).…”

Since 1982, farmers in the North West province and other parts of South Africa have noticed an increase in the incidence of lameness in cattle. Macro- and microscopical lesions of joints resembled osteochondrosis. Pre-trial data indicated that cattle with osteochondrotic lesions recovered almost completely when fed a supplement containing bio-available micro- and macrominerals of high quality. In the present trial, 43 clinically affected cattle of varying ages (1–5 years) and sexes were randomly divided into three groups. Each group was fed the same commercial supplement base with differing micro- and macromineral concentrations to determine the effect of mineral concentrations on the recovery from osteochondrosis. Both supplements 1 and 2 contained 25% of the recommended National Research Council (NRC) mineral values. Additional phosphate was added to supplement 2. Supplement 3, containing 80% of the NRC mineral values, was used as the control. Results from all three groups indicated no recovery from osteochondrosis. Urine pH of a small sample of the test cattle showed aciduria (pH < 6). Supplement analysis revealed addition of ammonium sulphate that contributed sulphate and nitrogen to the supplement. Supplementary dietary cation anion difference (DCAD) values were negative at -411 mEq/kg, -466 mEq/kg and -467 mEq/kg for supplements 1, 2 and 3, respectively, whereas the pre-trial supplement was calculated at +19.87 mEq/kg. It was hypothesised that feeding a low (negative) DCAD diet will predispose growing cattle to the development of osteochondrosis or exacerbate subclinical or clinical osteochondrosis in cattle.

“…Le pH et les concentrations en bicarbonates sanguins augmentent très rapidement pour des BE compris entre -200 et + 100 mEq/kg MS, atteignent un maximum pour des BE de la ration proches de 350 mEq/kg MS pour ensuite peu varier pour des BE compris entre 300 et 500 mEq/kg MS. De tels effets ont déjà été décrits chez le cheval (Mueller et al 1999), le poulet (Mongin 1981, Whitehead 1997, Murakami et al 2001 et le chat (Ching et al 1989), mais les données sur ces espèces étaient trop rares pour réaliser une approche quantitative.…”

Effet du bilan électrolytique de la ration sur l’équilibre acido-basique et les performances zootechniques des animaux domestiques à fort niveau de production

La maîtrise de l’alimentation des animaux à fort niveau de production est nécessaire pour éviter des pertes économiques importantes. Parmi les pistes explorées, le bilan électrolytique, défini comme [sodium] + [potassium]-[chlore], est une voie intéressante pour limiter la production d’acides à l’origine de troubles métaboliques. A partir de trois bases de données (vaches en lactation, porcs en croissance et ruminants en croissance), cette synthèse étudie par analyse de covariance, les réponses zootechniques et celles de l’homéostasie acido-basique en fonction de la valeur du bilan électrolytique de la ration. Les quantités ingérées, la production de lait à 4% et le gain moyen quotidien augmentent avec l’augmentation du bilan électrolytique. Dans le même temps, le pH et les concentrations en bicarbonates du sang suivent la même évolution. La chlorémie diminue fortement avec l’augmentation du bilan électrolytique : le chlore est l’ion le plus impliqué dans la régulation de l’homéostasie acido-basique. Enfin, le pH urinaire augmente avec l’accroissement du bilan électrolytique de la ration, la corrélation obtenue est très forte. La voie urinaire est donc la principale voie d’excrétions des ions, et le pH urinaire pourrait être un bon indicateur de la valeur du bilan électrolytique des rations distribuées. L’augmentation du bilan électrolytique de la ration est donc un moyen efficace de lutter contre la production d’acides liée au métabolisme intense des animaux à fort potentiel de production. L’homogénéité des résultats entre les différents modèles suggère un effet du bilan électrolytique à un niveau systémique, même si quelques différences entre ruminants et monogastriques laissent à penser un effet au niveau du rumen.
