Crude Protein Level

 Two experiments were conducted to investigate the effects of dietary crude protein level and degradability on milk urea nitrogen (MUN) content. In experiment 1, twelve multiparous lactating cows averaging 176 days in milk were divided according to DIM and milk production into three 4 × 4 Latin squares with four 2-week periods. Cows were fed four diets with different crude protein levels (13.0, 14.0, 15.0, and 16.0%, DM basis) with isocaloric, respectively. Crude protein levels had a low effect on milk yield and composition (P > 0.05), but a significant effect on MUN content. There were significant differences in the MUN content of cows fed either of the two diets (P < 0.01). In experiment 2, fifteen multiparous Holstein dairy cows averaging 91 days in milk were classified according to DIM and milk production into five 3 × 3 Latin squares with three 3-week periods. Cows were fed one of the three isocaloric and isonitrogenous diets with RUP being 30.8%, 36.2%, and 41.6% (CP basis), respectively. Milk yield, milk composition, and MUN content were not significantly affected by protein degradability, and there were no significant differences between any two dietary treatments (P > 0.05). These results indicated that MUN might be used as a parameter to monitor the change in dietary protein levels.

The Impact

The study aims to determine the impact of dietary crude protein levels on the hematological parameters of Japanese quail from growth to ovipositor. To this end, five feeds with different crude protein levels (18, 20, 22, 24 and 26%) were supplied to 700 quails of three weeks of age. These were subdivided into six batches, including three batches of females and three batches of males for each feed group. After subjecting the quails to diets containing the different protein levels, four samples were taken at the fourth, fifth, sixth and seventh week of age. The samples taken were analyzed using an SYSMEX XN 350 automated hematological analyzer. The results of this investigation indicated that non-significant differences (P > 0.05) were observed in hematological parameters in both female and male quails. This study showed that dietary crude protein levels had no impact on the health status of Japanese quails. Keywords: Japanese quails, Crude protein, Hematological parameters.
