“…Because of that, only older calves (≈ 21 days) may be fed liquid diet formula with non-lacteal protein source (NRC, 2001) or vegetable sources without adequate processing as to increase its utilization. However, Raeth et al (2016) have shown that partial replacement of milk protein for alternative protein sources (wheat gluten, soy protein concentrate, spray dried animal plasma and plant peptide powder) in MR formula may decrease ADG during preweaning phase, but still results in adequate performance, with calves doubling their birth weight by weaning.…”

SUMMARY Other than crude protein (CP), crude energy (CE) and crude fiber (CF) content, the adequate supply of essential amino acids (EAA) is an important factor in milk replacer evaluation. The aim of this study was to analyze milk replacer samples as regard to nutrients, especially EAA, composition and simulate the attainability of calves' requirements in different feeding systems. Forty-one milk replacer samples were collected from 14 brands and analyzed for nutrient composition. The near infrared spectroscopy technique was used for AA content estimation. Samples presented adequate levels of CP (21.2±2.90%) and ether extract (14.5±3.41%) for calves fed according to the conventional (4L/d), but not for intensive milk feeding system (>6L/d). High values of CF were observed in the samples (1.6±0.86%). The EAA composition of milk replacer samples was lower than expected for a liquid feed supposed to replace whole milk. None of the analyzed samples presented adequate lysine (5.72±1.09% CP) or methionine (1.65±0.38% CP) to meet calves' daily requirements, regardless of feeding system. Higher crude protein milk replacers are needed. Alternatively, supplementation of milk replacers with EAA is recommended.

“…Higher preweaning milk supply resulted in higher levels of numerous dipeptides and AA in plasma. This response can largely be attributed to CP intake, which was 7% higher at d 49 in the ELE group, and to the greater digestibility of milk proteins compared with vegetable proteins in the calf starter (Raeth et al, 2016). Although most EAA were elevated in the ELE group, the branched-chain AA were not different at d 49.…”

“…The fluctuating costs of MR have increased interest in cheaper alternatives. Other plant and animal protein options include modified wheat such as hydrolyzed wheat gluten protein, blood plasma proteins (PL), egg, and peptide protein powder (PP), although antinutritional factors and lower AA profiles plus decreased digestibility are a concern (Raeth et al, 2016). The NC-2042 group has evaluated many alternative proteins in MR. Thornsberry et al (2016) (Raeth et al, 2016).…”

Multistate dairy management research project NC-2042, which is part of the National Institute of Food and Agriculture, has devoted an ongoing objective to calf and heifer nutrition and management. Within this objective, colostrum research has been a priority due to continued opportunities to improve this area on US dairy farms. Research has focused on heating colostrum to reduce bacterial populations and pathogens while increasing IgG absorption. Research also identified other proteins that are reduced when heating colostrum. Studies indicated an apparent upper limit to IgG absorption from colostrum fed to calves. Additional studies have shed light on absorption of IgG from colostrum replacers and evaluated the use of lactoferrin and sodium bicarbonate in both maternal colostrum and colostrum replacers. Milk replacer formulation, feeding strategies, and the effect of calfhood nutrition on future performance have also been researched. Finally, water quality and its effect on calves and heifers have been studied. This review focuses on research done by multistate research project NC-2042 member states in the area of colostrum and calf nutrition and management.
