In Egypt, during the last ten years, rabbits play crucial role in animal production sector. But, they facing many obstacles including heat stress, diet quality, management skills and recent techniqulaties. In Egypt, rabbits are reared purposely to achieve family needs of protein and save some family cash income. Unfortunately, this led to a reduction in rabbit’s economic value, because more than 80% of rabbit production are in the hand of small-scale producers and some of them may not well qualified to breed rabbits. The current situation (increasing population census with increasing animal protein demand), is calling for expanding rabbit production efficiency and shifting it to large or industrial scale. This lofty step will require those small breeders to shift and expand their objectives of rabbit farming. So, this review will evaluate the current situation of rabbit production in Egypt, with references to the obstacles facing rabbit production. The role of researchers in guiding and training smallholders on rabbit farming and what are those breeders need to be well qualified in rabbit production. Trying to maximize rabbit production and lifting it up into industrial level.

: Twenty four healthy V-Line growing rabbits, 5 weeks of age and initial live body weight (LBW) of 722 ± 27 g, were selected and randomly assigned to one of four dietary experimental groups of 6 rabbits in each. The four groups of rabbits received basal diet ad libitum (Control group; T1) and basal diet plus 0.5, 0.75 or 1.0 g Biogen / Kg diet in the other three treated groups (T2, T3 and T4, respectively). Growth performance traits till 14 weeks of age in terms of live body weight, daily weight gain, feed conversion ratio, carcass characteristics, blood traits and the economic impact of adding Biogen to growing rabbit diets were tested. The obtained results indicated that LBW improved by about 4.29, 4.75 and 11.68%, respectively in T2, T3 and T4 groups supplemented with Biogen than the control (T1).

The experimental material involved 218 New Zealand White (NZW) rabbits, the progeny of 24 bucks and 93 adult does.

As compared with their unrestricted forms, the restricted indices I 8(HLM) and I 9(HLM) would entail an only a slight reduction in accuracy of selection (r TI = 0.76 and 0.72, respectively) with acceptable improvement in WW (+104.7 and 108.2gm, respectively) and SW (+119.8 and 108.1gm, respectively) with an unfavorable increase in HLB by 0.37 and 0.07%, respectively. Conclusively , Use of weaning weight (WW) and slaughter weight (SW) as sources of information (I 2 ) in the following index: (r TI = 0.83) would be recommended to maximize the post-weaning growth traits regardless of the deterioration in carcass tissue weight distribution. However, the following restricted index: would be a preferred choice to the breeder, taking into consideration the expected deterioration in carcass tissue weight distribution, for biological and rabbit meat consumer desires reasons.

-------------------------------------------------------------------------------------------ABSTRACT : This study was intended to evaluate the effect of Moringa Oleifera leaf meal (MOLM) on reproductive hormones and semen quality traits in male rabbits. A total number of 24 New Zealand White (NZW) rabbits at 42 weeks of age, having an average body weight 3.00 ± 0.15 kg, were randomly divided into four equal treatment groups of six rabbits each. The 1 st group (control) was fed a basal diet. The 2 nd , 3 rd and 4 th treatments were fed on diets at 2.5, 5 and 7.5% MOLM inclusion levels of the total diet, respectively. Blood samples were collected through the marginal ear vein from each rabbit for biochemical and hormonal assay using standard procedures. In addition to, semen samples were collected weekly for 8 weeks and were analyzed for semen quality traits. Results of this experiment showed that, the use of moringa leaves in the diets of male rabbits led to a significant (P≤0.05) improvement in ejaculate volume, sperm concentration, live sperm, normal sperm and sperm motility compared to the control group. The results also showed a higher level of gonadotropic hormones (FSH, LH) and testosterone in rabbits fed on moringa compared to control group rabbits, decrease in total cholesterol and LDL-cholesterol in the groups fed diets containing moringa. It was also noted that there was an increase in the levels of total protein and HDL-cholesterol in the same groups, compared to the control group. Plasma ALT and AST decreased with all treatments of MOLM and this indicates that it has a role in improving liver health. In conclusion , this study showed that replacement of 2.5, 5 and 7.5% of MOLM inclusion levels of the total diet seems to have a positive effect on blood biochemical, physiological hormonal changes and semen quality on male rabbits, and it could be used as a sexual promoter.

The aim of this work is to investigate the consequences of selection for post-weaning growth performance on carcass composition and carcass meatiness traits. Seven selection indices were applied using estimates of genetic and phenotypic parameters on 218 New Zealand White (NZW) rabbits, progeny of 24 bucks and 93 does, via a multi-trait animal model. Slaughter weight (SW) and daily gain between them (DG) were used as sources of information. The breeding objective was to enhance the profitability of NZW rabbit breeders by maximizing and The carcass composition was represented as the percentage of dissected side weight deposited as muscle (MP), Fat (FP), and bone while carcass meatiness traits were represented as carcass muscle: bone ratio (MB), and muscle: fat ratio (MF). The heritability estimates (h 2 ) were 0.69, 0.44 and 0.54 for WW, SW and DG, respectively. Carcass composition traits showed moderate estimates of h 2 for MP (0.31) and FP (0.35) and a very high value for BP (0.91). The h 2 values for carcass meatiness traits were 0.42, 0.43, 0.89, and 0.75 for CW, DP, and from -0.43 to -0.31 unit). Carcass meatiness traits are expected to be more favorable in terms of higher DP (ranged from 0.14 to 0.38 unit) and MB ratio (ranged from 0.28 to 0.36 unit) and less favorable in terms of MF (ranged from -0.23 to -1.60 unit). Conclusively, the results obtained in the present study suggested that selection based on the single trait index I 5 including the weaning weight trait would be recommended to improve the given aggregate genotype traits for being an early, single, and easy-to-measure.

Seven selection indices were applied using estimates of genetic and phenotypic parameters on 218 New Zealand White (NZW) rabbits, progeny of 24 bucks and 93 does, via a multi-trait animal model. Slaughter weight (SW) and daily gain between them (DG) were used as sources of information. The breeding objective was to enhance the profitability of NZW rabbit breeders by maximizing and The carcass composition was represented as the percentage of dissected side weight deposited as muscle (MP), Fat (FP), and bone while carcass meatiness traits were represented as carcass muscle: bone ratio (MB), and muscle: fat ratio (MF).
