RESEARCH BRIEFS


Performance and amino acid utilization of early lactation cows fed NovaMeal

Mjoun et al., 2010. Journal of Dairy Science. 93:3176-3191.

A lactation study was conducted to evaluate milk production, milk composition, plasma metabolites and the mammary uptake of amino acids in cows fed distillers grains as the primary protein supplement in early lactation. Distillers grains were fed as DDGS (10.8% fat, 31.3% CP) or NovaMeal (3.5% fat1, 34.0% CP).

Key Study Results

  • Cows fed NovaMeal had similar dry matter intake and milk yield, and increased milk protein percentage and yield (P = 0.03 and P = 0.05, respectively) compared with those fed soybean-based diets.
  • Cows fed NovaMeal have a greater plasma methionine concentration (P < 0.001) and a tendency for greater mammary uptake of methionine (P = 0.07) vs. cows fed soybean-based diets.
  • While cows fed NovaMeal have a lower plasma lysine concentration (P < 0.01), the mammary uptake of lysine was similar to cows fed soybean-based diets, which is due to greater extraction efficiency of lysine in cows fed NovaMeal (P < 0.001).


Performance and amino acid utilization of mid-lactation cows fed increasing amounts of NovaMeal

Mjoun et al., 2010. Journal of Dairy Science. 93:288-303.

A lactation study was conducted to evaluate the effects of feeding increasing amounts of NovaMeal1 (3.5% fat, 34.5% CP) at the expense of soybean products to mid-lactation dairy cows on milk production, milk composition, plasma metabolites and the mammary uptake of amino acids.

Key Study Results

  • Milk fat increased as the level of NovaMeal in the diet increased (P < 0.05), while milk protein increased up to 20% inclusion of NovaMeal (P < 0.05; Table 1). Dry matter intake and milk yield were similar for all diets.
  • Plasma methionine concentration increased as the level of NovaMeal in the diet increased (P < 0.05), and plasma lysine decreased as level of NovaMeal in the diet increased (P < 0.05).
  • The mammary uptake of both methionine and lysine was similar for all diets, demonstrating that the high demand for metabolizable amino acids to synthesize milk and milk protein was not limited when NovaMeal was fed as the primary protein source, up to 30% inclusion.


Ruminal degradability and intestinal digestibility of protein and amino acids in NovaMeal and other common soybean and corn protein sources

A study was conducted to compare ruminal degradation and intestinal digestibility of protein and amino acids of different protein sources (NovaMeal, as well as common soybean and corn protein sources), using in situ and in vitro techniques.

Mjoun et al., 2010. Journal of Dairy Science 93:4144-4154.

Key Study Results

  • NovaMeal had the greatest RUP and lowest RDP of the protein sources evaluated.
  • NovaMeal had the greatest RUPD (RUP digestibility) of the protein sources evaluated.
  • NovaMeal had the lowest ruminal degradation of methionine. Intestinal digestibility of methionine did not differ by source, suggesting greater intestinal absorption of methionine from NovaMeal.
  • Lysine content both after rumen incubation and intestinal digestibility of lysine were greatest for soybean sources vs. corn sources. However, the amount of lysine absorbed intestinally did not differ between NovaMeal and soybean meal.
  • These results suggest that methionine and lysine availability can be comparable between soybean and corn sources, and one must look further than amino acid composition of the feedstuff when evaluating feeds for a diet.
