“…Total proteins pattern is the same in both breeds: this parameter shows a mean value of 5.47g/dl and of 5.42g/dl, respectively, in Thoroughbred and Arabian foals on the first day of life and reaches 6.25g/dl in Thoroughbred and 6.47g/dl in Arabian foals at the 30 th day of life. The contemporary decrease of urea, which falls from the mean value of 18.7mg/dl in Thoroughbred and 18.8mg/dl in Arabian foals after birth to 12.98mg/dl in Thoroughbred and to 13.1mg/dl in Arabian foals on the 30 th day of life, confirms the growth requirements of the foal, as suggested by the high protein retention/protein intake ratio observed during this period (Doreau et al, 1986). It could be associated with an increased demand for amino acids necessary for structural and enzymatic protein synthesis, according to previous studies (Bauer et al, 1984).…”

The maturation of nitrogen metabolism was studied in six Thoroughbred and six Arabian foals. Rectal temperature, heart and respiratory rates and serum concentration of several hematochemical parameters (total protein, urea, uric acid, creatinine, and albumine) were monitored from birth to 5 months of age. In both breeds, all the parameters except albumine showed significant differences over time (P<0.05). The two breeds did not differ from each other at any time point. Statistically significant decreases in urea and creatinine concentrations were related to the growth needs of foals during this critical period of development.

“…They were fed 100% of their requirement for milk yield. Individual milk yield was estimated weekly from the 2nd week after foaling, using the average daily gain (ADG) achieved by the foal the previous week [5]. The milk yield for the following week was estimated postulating that milk yield increases by 1 kg per day until it reaches the maximum of milk production, which is known to be achieved at 2 months of lactation [7].…”

Effect of fast vs. moderate growth rate related to nutrient intake on developmental orthopaedic disease in the horse

et al. 2006

-Osteochondrosis and other developmental orthopaedic diseases (DOD) constitute major problems in the horse industry. High food allowances and fast growth might be contributory factors. The aim of this experiment was to test the effect of high balanced nutrient allowances and associated fast growth, on the prevalence of several DOD. This study was carried out from birth to one year of age. Foals of a high feeding group (HL, n = 20) were fed 130% (0 to 2 months) and 150% (2 to 12 months) of the moderate level group (ML, n = 19, 100% of INRA recommendations). All foals were radiographed at 5.5 and 11 months, and 8 foals from each group were necropsied at 12 months of age for gross inspection of joints. Body weight, height at withers and cannon width were higher at 12 months in the HL group (+88.4 kg, +4.6 cm, and +2.1 mm respectively). The gains in body weight were 1254 and 873 g per day in the HL and ML respectively during the 0-6 month period, and 668 and 528 g per day in the HL and ML respectively during the 7-12 months period. The occurrence and severity of limb DOD were not statistically different in the HL and ML groups. Fast growth was positively correlated to the occurrence of some DOD lesions, but the body weight was more weakly correlated to the prevalence of DOD than cannon width or height at withers. The power of correlation varied for different types or localisations of lesion. In conclusion, high balanced feeding level was not a sufficient factor in our study, but fast development was a factor of risk for DOD. The lower correlations obtained with body weight do not support the theory that biomechanical limb loading due to increased bodyweight alone increases risk for osteochondrosis. High endomembranous or endochondral ossification rate would be more critical in causing DOD. La présence et la gravité des AOAJ des membres n'ont pas été statistiquement différentes dans les deux groupes. Une croissance rapide a été associée à la présence de certaines AOAJ, mais le poids vif a été moins fortement corrélé à la prévalence des AOAJ que la largeur du canon ou la hauteur au garrot. La puissance des corrélations dépendait de la localisation des lésions. En conclusion, des apports nutritionnels élevés et équilibrés n'ont pas suffi à induire des AOAJ, alors que le format et/ou la croissance ont été des facteurs de risque. L'hypothèse du seul effet mécanique lié à la surcharge pondérale pour justifier l'apparition des AOAJ n'est pas vérifiée par cette étude. En revanche, une intense ossification intramembraneuse ou endochondrale induite pourrait constituer un facteur déterminant de l'apparition des AOAJ.cheval / nutrition / croissance / développement / ostéochondrose

-The trends of the physicochemical properties, chemical constituents and main nitrogen fractions of Haflinger mare milk were studied. Milk samples were collected at d 4,20,40, 60, 80, 120, 150 and 180 post-partum, by hand-milking from 5 mares, 7-14 years old (4-11 parities) and 400-490 kg live weight. Density, pH, titratable acidity, fat, protein, lactose and ash varied significantly during the first lactation period, while the freezing point showed statistically no significant modifications. The contents of fat, protein and ash diminished. In addition, the gross energy value tended to decrease and the lactose content increased. Total N content decreased significantly (P < 0.0001), especially between d 4 (515 mg) and d 40 (286 mg) and, to a lesser degree, until d 180 of lactation (255 mg . 100 g -1 milk). The casein number varied significantly (P < 0.001), particularly between the beginning (56.32%) and the end (45.40%) of lactation. The trend of non-protein N and globulin N fractions was different; both the 2nd and 3rd month showed the lowest values of the entire lactation (P < 0.05). The non-protein N proportion (NPN × 100 / total N) increased significantly (P < 0.001) from the beginning (7.74% at d 4) to the end (12.37% at d 180) of lactation. The globulin N proportion increased from the end of the 4th lactation month, reaching in the final period an average value of about 10% of total N, but with an irregular trend (P > 0.05).Haflinger horse / nursing mare / lactation stage / milk properties / milk composition / nitrogen fractions Résumé -Propriétés physico-chimiques, composition chimique, valeur énergétique et fractions azotées du lait de jument de race Haflinger pendant 6 mois de lactation.
