A Grey Rabbit That Could Be Your Perfect Pet

The Carmagnola Grey Rabbit is a medium-sized breed that can weigh from three to four kilograms. Its ears are up to 14 cm long. They can be rosolare (pot-grown) or trimmed to a desired size. The adult Carmagnola Grey Rabbit weighs between three and four kilograms but can weigh up to five kilograms.

One study showed that the year of kindling significantly influences the LSB and LSW of the Carmagnola Grey Rabbit Breed. The productivity of the breed improved after the first delivery, at a higher kid-weaning age, and decreased during the summer. This difference in productivity does not mean that one year is better than another.
Reproductive traits were highly influenced by the year of kindling and parity. LWW increased from the first to the second parity and stayed in the same range after the second. The amount of WM was significantly greater during the rainy season, spring, and winter seasons, suggesting that the prevailing environmental conditions may have contributed to better reproductive performance.
The weight of the doe before mating was also important in determining the litter size. This could be improved with better nutrition for the doe. Poigner et al.(2000) also examined the effect of birth weight and litter size on the growth rate of the Carmagnola Grey Rabbit Breed.
In general, the breed is affected by the type of season in which it was kindled, the year of kindling, and the parity of the litter. In the winter, temperatures can drop to 0degC.
The use of maize cobs as a complete and balanced food source can improve the growth performance of Carmagnola grey rabbits. According to a study published in the Nigerian Journal of Animal Science, the addition of maize cobs to the diet of this breed can improve growth and productivity. In addition, it is beneficial for the rabbits’ health and well-being.
Maize cobs were heated for 15 minutes at 65 C to evaluate their nutritional value and proximate composition. After the heating, the proximate composition was analyzed using the AOAC 2000 methods, and the gross energy content of the cob was determined using a bomb calorimeter. The bomb calorimeter is a device that measures energy from food using diabatic oxygen.
The study was conducted on forty-five weaner rabbits obtained from the Moor Plantation, Ibadan, Oyo State, Nigeria. These rabbits were randomly assigned to one of five dietary treatments, with three replications of each treatment. They were housed in wire mesh cages with wooden floors and a drinking and feeding trough. The rabbits were fed the experimental diets ad libitum.
Cross-breeding of rabbit breeds is an effective technique for improving performance traits. This process involves crossing males and females. It is an economical way to increase the number of rabbits in a particular region. However, there are few studies focusing on reciprocal crossbreeding in south-south Nigeria.
The weaning performance of the Carmagnola Grey Rabbit breed was evaluated by researchers over eight years. They looked at the effect of environmental factors on the performance of the rabbits during the early months of life. The trial was conducted at the breeding rabbitry of the University of Turin. The rabbits were born from a pure nucleus of the local breed and reared under semi-controlled conditions.
The year of kindling had a significant effect on the LSW and LSB. LSB was significantly higher in 2004-05 than in 2002-03, while LSW was significantly lower. The effect of the year on the LSW was less pronounced.
The percentage of litters that were weaned was lower than in the control group. For the VW, BH, and EN, the percentage was much lower. The gap between the control group and the other three groups increased as the number of kits was reduced.
Breed and parity are important factors in determining weaning performance. Early-parity animals are likely to grow faster and mature until adulthood, whereas older-parity animals grow more slowly. Higher parity also results in higher birth weight. This is attributed to the fact that older dams use the feed more effectively than younger ones.
The weaning performance of the Carmagnola Grey Rabbit breed was assessed by many researchers. Some authors examined the performance of doe rabbits under a tropical climate. Other researchers looked at rabbits under Egyptian conditions and studied reproductive performance. They also studied the effects of non-genetic factors on litter performance.
The Carmagnola Grey Rabbit is a reputable breed of rabbits known for its high productivity. Using an intensive production system, breeding can be done throughout the year. In addition, a high-quality litter can be produced in less than three months. Genetic evaluation of some economic traits in a mother line of this breed reveals the presence of multiple genetic variants.
The carcass traits included dressed weight, dressing percentage, and weight of organs. The data was subjected to analysis of variance with Duncan’s new multiple range test to separate significant means. The study identified several genetic groups with significant differences in growth, reproduction, and carcass traits. The NZW x CHA genetic group significantly influenced body weight and post-weaning weight.
The estimated rank correlations for weaning weight and slaughter weight were low, while those for daily weight gain were moderate. The genetic trend for daily weight gain was calculated as the regression coefficient of trait breeding values for the year of birth and generation number. This value increased by 1.08 g/d during the fattening period.
IRAQI, M. M., et al., evaluated some of these economic traits in Gabali rabbits. Their research was published in the American-Eurasian Journal of Sustainable Agriculture.
