“…Thus, as a fodder plant, /. crithmoides appears to have a satisfactory composition for mineral nutrition, better than salicornia hay, and above the minimum (9%) recommended for ruminants (Annenkov, 1982). Salinity had no significant effect on crude protein content.…”

“…Cette controverse scientifique internationale a maintenant pris fin et, à quelques exceptions près, les bases de calcul de l'ARC ont été abandonnées. Il en résulte un meilleur accord international, notamment entre les apports recommandés américains (NRC 1988), soviétiques (Annenkov 1979) et français (INRA 1978(INRA , 1988). Les valeurs de l'ARC (1980) sont indiquées dans le tableau 1 comme références de besoin minimum, sachant qu'il ne s'agit pas d'apports recommandés (avec une marge de sécurité) et qu'elles n'ont jamais été appliquées sur le terrain.…”

Il existe un bon accord international pour les recommandations d’apport en magnésium, sodium, potassium, soufre et oligo-éléments chez la vache laitière ; il subsiste néanmoins quelques différences en ce qui concerne le phosphore et le calcium. L’essentiel de ces divergences concerne le besoin d’entretien en P et l’absorption réelle de Ca. Le faible besoin d’entretien des normes américaines (NRC 1988) correspond à des régimes pauvres en fourrages pour lesquels le recyclage salivaire de P est faible. L’absorption réelle de Ca se situe entre 35 et 38 % pour l’ensemble des systèmes, à l’exception du SCA australien (60 %) ; cette valeur résulte probablement de l’adaptation parfaite d’un organisme animal soumis à un apport calcique très insuffisant, par conséquent peu compatible avec les conditions pratiques. Les valeurs retenues pour la croissance, la gestation et la lactation sont par ailleurs très proches dans les différents systèmes. Le système français (INRA 78 et INRA 88) représente en fait de véritables recommandations pratiques d’apport visant à la satisfaction des besoins phosphocalciques de tous les animaux, incluant par conséquent une marge de sécurité et prenant en compte le cycle mobilisation-restauration des réserves minérales osseuses chez la femelle laitière. Ces recommandations sont nécessairement supérieures à celles correspondant au strict besoin minimum.

“…Nutritional demands of the cow increase during the last third of gestation due to exponential fetal growth and during lactation due to demands for milk production ( NASEM, 2016 ). Both of these physiological states disrupt trace mineral homeostasis of the dam to partition trace minerals from the diet or storage (primarily liver) to the placenta ( Mills and Davies, 1979 ) or the mammary gland ( Annenkov, 1982 ). Because essential trace minerals Cu, Zn, and Mn are constituents of metalloenzymes and cofactors in many enzyme systems ( McDowell, 1992 ), they are important in almost all normal biochemical processes ( Spears, 1999 ).…”

To determine effects of Cu, Zn, and Mn source and inclusion during late gestation, multiparous beef cows [n = 48; 649 ± 80 kg body weight (BW); 5.3 ± 0.5 body condition score (BCS)] were individually-fed hay and supplement to meet or exceed all nutrient recommendations except Cu, Zn, and Mn. From 91.2 ± 6.2 d pre-calving to 11.0 ± 3.2 d post-calving, cows received: no additional Cu, Zn, or Mn (control, CON), sulfate-based Cu, Zn, and Mn (inorganic, ITM) or metal methionine hydroxy analogue chelates of Cu, Zn, and Mn (MMHAC) at 133% recommendations, or a combination of inorganic and chelated Cu, Zn, and Mn (reduce and replace, RR) to meet 100% of recommendations. Data were analyzed with treatment and breeding group (and calf sex if P < 0.25 for offspring measures) as fixed effects, animal as experimental unit, and sampling time as a repeated effect for serum, plasma, and milk measures over time. Post-calving cow liver Cu was greater (P ≤ 0.07) in MMHAC compared with all other treatments. Calves born to RR had greater (P ≤ 0.05) liver Cu than ITM and CON, and MMHAC had greater (P = 0.06) liver Cu than CON. Liver Mn was less (P ≤ 0.08) for RR calves than all other treatments. Calf plasma Zn was maintained (P ≥ 0.15) from 0 to 48 h of age in ITM and MMHAC but decreased (P ≤ 0.03) in CON and RR. Gestational cow BW, BCS, and metabolites were not affected (P ≥ 0.13) by treatment, but gestational serum thiobarbituric acid reactive substances (TBARS) were greater (P = 0.01) for CON than MMHAC. Treatment did not affect (P ≥ 0.13) calf birth size, vigor, placental size and minerals, or transfer of passive immunity. Neonatal calf serum Ca was greater (P ≤ 0.05) for MMHAC than all other treatments; other calf serum chemistry and plasma cortisol were not affected (P ≥ 0.12). Pre-suckling colostrum yield, and lactose concentration and content, were greater (P ≤ 0.06) for MMHAC compared with ITM and RR. Colostral triglyceride and protein concentrations were greater (P ≤ 0.08) for RR than MMHAC and CON. Cow lactational BW and BCS, milk yield and composition, and pre-weaning calf BW and metabolism were not affected (P ≥ 0.13) by treatment. Lactational serum TBARS were greater (P = 0.04) for RR than CON at d 35 and greater (P ≤ 0.09) for MMHAC at d 60 than all other treatments. Source and inclusion of Cu, Zn, and Mn altered maternal and neonatal calf mineral status, but calf size and vigor at birth, passive transfer, and pre-weaning growth were not affected in this study.
