Abstract/ Executive Summary:

The present study was conducted to evaluate the effect of different levels of methionine supplementation on feed intake, nutrient digestibility and growth performance of growing rabbit. Sixteen weaned crossbred New Zealand White (NZW) growing rabbits (30-35 d) were distributed into four treatment groups having four replications in each group using a Completely Randomized Design (CRD). Basal diet composed of green grass (dhal grass) and concentrate mixture which was offered ad libitum basis for 56 days period. Four levels of methionine such as 0.0% (control), 0.15%, 0.25%, and 0.35% were supplemented randomly to rabbits. Results showed that supplementation of methionine did not affect green grass intake. Cumulative as well as daily concentrate and DM intake were significantly (p<0.05) higher for all methionine groups than control group. Final body weight gain as well as daily, weekly and cumulative body weight gains were improved significantly with increasing level of methionine. It was found that methionine had significant (p

Objectives:

To evaluate the different levels of methionine supplementation with concentrate mixture on feed intake, nutrient digestibility and growth performance of rabbit.

Methodology:

The experiment was carried out at the- Shahjalal Animal Nutrition Field Laboratory, Bangladesh Agricultural University, Mymensingh for a period of 56 days. All of the experimental animals were housed individually in all steel, Quonset style cages (Harris, 1983), measuring 1.95mx1.80mx 1.27m in dimension. A J-shaped screened metal feeder and 250ml bottle waterer with steel straw were provided in each cage. Fifteen weaned crossbred New Zealand White (NZW) growing rabbits aged about 30-35 days and the average initial live weight of the rabbits ranging from 285 to 295 gm, were randomly assigned to four dietary treatment in a Completely Randomized Design (CRD) each having four replications. The dietary treatments were: To = Green grass + (Concentrate mixture containing 0.0% methionine); T, = Green grass + (Concentrate mixture containing 0.15% methionine); T2 = Green grass + (Concentrate mixture containing 0.25% methionine); T3 = Green grass + (Concentrate mixture containing 0.35% methionine). The data were analyzed using the "MSTAT" statistical program to compute analysis of variance (ANOVA) for a Completely Randomized Design (CRD). Duncan's Multiple Range Test (DMRT) was also done for different parameter to compare the treatment means for different Parameter.

Achievement/Findings:

Under present experimental condition, it may be concluded that 0.25% of supplementation of methionine in the diet of growing rabbit might be suggested for rabbit rearing.
