To evaluate the effect of different rearing systems and sex on productive performance and carcass composition and quality, 80 rabbits (40 males and 40 females) of Carmagnola breed were reared from 9 to 16 weeks of age in individual California type cages (0.12m(2)) or in group ground pens (0.25m(2)/head). The animals were kept in standard and uniform environmental conditions and fed the same ad libitum pellet feed. Data on live weight and feed intake were recorded. At the end of the fattening period 10 animals per group were slaughtered and data provided in the World Rabbit Science Association (WRSA) standard method were collected, as well as pH and meat colour. Animals reared in ground pens showed lower productive performances, while, as to slaughtering performances, rabbits reared in cages showed the highest slaughtering weight and also the highest weights for most body parts. Gender slightly affected productive and slaughtering performances: females showed higher feed consumption and higher perirenal fat weight than males. Meat colour parameters showed significant differences in Longissimus lumborum and Biceps femoris due to housing systems and gender effects. In both muscle, rearing system affected pH only 24h after slaughter.

    • "The same tendency continued at 90 and 120 days old in males, as well as in female rabbits, and also in females at 150 days of age. According Lazzaroni et al. (2009) the gender affects less productive and slaughtering performance, as the females showed a higher feed consumption and better productive performance, similar trend was observed in the obtained from results in this study до outdoor reared rabbits. According Preziuso et al. (2008) meat of rabbits grown in the open less pale indicates significantly higher content of fat, which is likely positive, as it is associated with reduced loss during cooking and positive low saturated fatty acids and high mono saturated fatty acids.

    ABSTRACT: The purpose of this study is to trace the rabbit weight development from 30 to 150 days of age of newly bred Vesselina and most widely used in the country meat breeds - White New Zealand and Californian, under extensive farming conditions. The experiment was conducted in a rabbit farm at University of Forestry, in wooden cages. The results showed that with the highest live weight and weight gain are characterized animals from Vesselina and with the lowest - animals by the Californian breed. © 2015, National Centre for Agrarian Sciences.

    • "The proportions of both perirenal and total dissectible fat, which includes scapular, inguinal and perirenal fat, were significantly lower in rabbits reared at the lower stocking density than in rabbits reared at the higher stocking density. Similarly, Lazzaroni et al. (2009b) observed decreased fat deposition in pen-housed rabbits (higher disposable space) compared with rabbits reared in individual cages. Villalobos et al. (2008) observed that the proportion of scapular fat increased linearly with increasing levels of stocking density, but perirenal fat was unaffected. "

    • "Rabbit is used for many researches as an important livestock for production of meat in most Mediterranean countries, offering more than 30% of world production. Besides, rabbits reproductive capacity, a feature that is attractive for its use as lab animal too.(Lazzaroni et al., 2009). The protective effect of myrrh and/or vitamin C against DZN-induced oxidative stress in our rabbit model could be either direct by inhibiting lipid peroxidation and scavenging free radicals or indirect through the enhancement of the activity superoxide dismutase and CAT; the enzymatic free radicals' scavengers in the cells. Therefore,"

    ABSTRACT: Diazinon (DZN) is a widely used organophosphrus synthetic and acaricide widely used for agricultural and veterinary purposes. However, its human and animal exposure leads to hepatocardiotoxicity. Our experimental objective was to evaluate protective effects of Myrrh; Commiphora molmol or/ and ascorbic acid; vitamin C against DZN-induced hepatocardiotoxicity in healthy male white New Zealand rabbits (Oryctolagus cuniculus). DZN-treated animals revealed significant alterations in serum biochemical parameters related to hepatic and cardiac injuries. There was a significant increase in hepatic and cardiac lipid peroxidation and significant inhibition in tissue antioxidant biomarkers due to DZN intoxication. Both myrrh and vitamin C protect against DZN-induced serum as well as hepatic and cardiac tissue biochemical parameters when used alone or in combination along with DZN-intoxication. Furthermore, both myrrh and vitamin C produced synergetic hepatocardioprotective and antioxidant effects. Therefore, it could be concluded that myrrh and/or vitamin C administration able to minimize the toxic effects of DZN by its free radical-scavenging and potent antioxidant activity.
