Abstract

The present study was conducted to determine the effects of replacing alfalfa hay with different proportions of fresh alfalfa on performance and serum biochemical parameters of dairy cows. Eighteen healthy Holstein cows at mid-lactation with similar parity, body weight and milk yield were randomly divided into 3 groups with 6 cows per group. Different proportions[0 (control group), 50% (trial group Ⅰ) and 75% (trial group Ⅱ)] of alfalfa hay in a basal diet were replaced with fresh alfalfa, and those diets were used to feed cows in different groups. The pretrial lasted for 15 d, and the trial lasted for 30 d. The results showed as follows:1) dry matter intake and milk yield were not significantly affected by replacing alfalfa hay with different proportions of fresh alfalfa (P>0.05), but milk somatic cell count of trial groups was significantly lower than that of control group (P<0.05). 2) Apparent nutrient digestibility was not significantly affected by replacing alfalfa hay with different proportions of fresh alfalfa (P>0.05). 3) Serum total protein, albumin, globulin, cholesterol, glucose, triglyceride, high-density lipoprotein and low density lipoprotein contents, and alanine transaminase, aspartate aminotransferase and alkaline phosphatase activities were not significantly affected by replacing alfalfa hay with different proportions of fresh alfalfa (P>0.05). Serum urinary nitrogen content of trial group Ⅰ was significantly higher than that of control group and trial group Ⅱ (P<0.05), but no significant difference was found in control group and trial group Ⅱ (P>0.05). 4) Compared with the control group, the economic benefit of trial groups Ⅰ and Ⅱ was increased, especially trial group Ⅱ and it had the highest added profit which was 9.05 yuan/(head·d). Therefore, alfalfa hay can be partially replaced with fresh alfalfa in dairy cow diet without effects on performance, digestion metabolism, serum biochemical parameters and improve the economic benefits.
