digestible nutrient and in situ and estimated intestinal CP
digestibility was presented in Table 5. From the data in Table
5, we can find that protein secondary structure has no correlation
with protein chemical profiles and protein subfractions.
For truly digestible nutrients correlation, alpha-helix and
beta-sheet ratio has positive correlation (p ¼ 0.044) with tdCP
with R ¼ 0.55. For in situ rumen CP degradability and intestinal
CP digestibility, the a-helix to b-sheet ratio was found to be a
negative correlated (p ¼ 0.038) with total CP digestibility
(T_DCP) with R ¼ 0.56. The result in present study was in
good agreement with previous study [22,34]. The negative
correlation may imply that a higher a-helix to b-sheet ratio
could lead to lower total CP digestibility in the rumen and
intestinal of ruminants.
From the above correlation analyses, we found that,
although some parameters of protein molecular structure has
correlation with protein nutrient profiles, it showed weakly
relationship between them. The result was differed from
previous studies [2,36,37], which found that protein molecular
spectroscopic data are highly related to protein nutrient parameters
in various kinds of feedstuff. This phenomenon in
our study could be explained by different drying and
fermentation process. Therefore, it needs to do further
research with large sample size and to know how processing
methods affect the correlation between protein molecular
structure and protein nutrient values. Then we can do
multiple-regression analysis to develop potential prediction
equations protein nutrient supply to dairy cattle based on
protein molecular structure parameters.
