Abstract
This study aimed to : A feeding experiment with V-line rabbits in wire batteries for eight weeks in a private farm was carried out during 2014 to study the possibility of substituting soya bean (SB) in rabbit’s diet by using another cheaper-proteinous ingredient, mainly ground sieving product of berseem (Egyptian clover) seeds (GSPB). Two diets (GSPB or SB-containing) were formulated (to be iso-caloric and iso-nitrogenous) and pelleted to be offered ad lib. At one meal daily to the rabbits (six rabbits per diet per battery), which were individually housed. Methods & Results Different observation were inspected daily besides daily measurements of individual live bodyweight, food intake and water consumption to calculate live bodyweight gain, food conversion ratio, and economic efficiency. At the last five days of the feeding experiment, feces were individually and quantitatively collected from three rabbits per diet, sampled, kept refrigerated and chemically analyzed (the diets also were chemically analyzed) to calculate digestibility coefficient of different nutrients. At the end of the experiment, three rabbits per diet were slaughtered (for carcass traits, weighing and calculating percentages of different carcass’ parts dressing and boneless meat besides chemical analysis of rabbits’ meat) and blood samples were collected and immediately sent to clinical laboratory for hematological and biochemical analyses. He obtained results could be summarized in the followings : Bloody urine was excreted by control rabbits (SB) but not by the treated ones (GSPB). Comparing with SB diet, the GSPB diet led to higher live bodyweight throughout all the feeding weeks. The GSPB diet led to higher total live bodyweight gain throughout most of the feeding weeks and during the entire feeding period.The GSPB diet led to higher daily live bodyweight gain for all the feeding weeks and during the entire feeding period.The GSPB diet led to lower food intake throughout most of the feeding weeks and during the entire feeding period. The GSPB diet led to lower drinking water consumption throughout most of the feeding weeks and during the entire feeding period. The GSPB diet led to better food conversion ratio throughout most of the feeding weeks and during the entire feeding period. The GSPB diet led to higher economic efficiency.The GSPB diet led to higher dressing and boneless meat percentages. Concerning blood analysis, GSPB diet positively affected the rabbits’ health. Conclusion : Consequently, GSPB is very economic in rabbits feeding and could result in improving the growth performance, food utilization, dressing and boneless meat percentages, and chemical composition of the rabbits meat without any negative effects on rabbit’s health.
