For a farmer, the weight of rabbits is the main indicator of production efficiency. Among other pets, they are the fastest growing. On average, by 4-5 months, pets grow by 65%, and after about 8-10 months the eared ones gain the maximum mass characteristic of a particular species. What are the rates of development in different breeds, how many rabbits should weigh at certain periods of life and what weight is considered the norm for adults - you will learn from this article.
New-born eared animals of different breeds can weigh a rabbit depending on age. Being born blind and hairless, thanks to mother's milk, for the first 25-28 days of life (about 4 weeks), the weight of the rabbit increases about 10 times. Then the growth rate decreases slightly. But for the next three to four months, intensive weight gain is observed.
By 4-5 months, animals reach sexual maturity, gaining about 65-70% of the adult average rabbit weight. At this age, individuals weigh about 3.5 kg.
The maximum number of kilos eared give 9-10 months of life. There are minor differences depending on the breed. They need to be studied in order to achieve the goal for which the farmer organizes a rabbit farm.
What determines the quality set of body weight
Farm productivity is directly related to the rate at which animals gain weight. This component of success can be influenced by considering the following parameters:
- natural features of the breed;
- hereditary qualities of livestock;
- maternal qualities of the female;
- living conditions created for animals;
- quality and diet;
- correctly conducted perinatal and infant periods.
When planning a farm, the owner must decide for what purpose rabbits will be raised. If the direction of the economy is only meat - you need meat species of animals.
If the farmer plans meat-skin direction, then the livestock for breeding must choose the appropriate. Rabbit giant breeds show the best results of weight gain at minimum cost.
What are the largest rabbits
The giant rabbits grow faster than others: flandr, white giant, French ram, Californian and New Zealand white. Breeding these species is cost-effective for several reasons. The first is the precocity of these breeds and rapid, in comparison with others, growth rates.
In addition, the giants can easily adapt to any conditions of detention, tolerate even adverse cold weather. Having a strong immunity to a wide range of diseases, these rabbits can breed well. In one area the giant female usually has from 10 babies.
By the 3rd month of life, giant rabbits have a mass of more than 2.5 kg. The adult rabbit of giant breeds weighs 5-7 kg.
Of course, each eared species has its own development features by months. Below is a table with detailed information on how much a rabbit weighs depending on age:
Characteristics of different breeds
Certain eared species can be used for different results in production. There is only meat - their weight is large, they gain it quickly and easily. If the rabbits are downy, then the weight gain indicators are not so important. But there are also combined breeds. They are well manifested in the meat direction, while successfully producing fluff or good skin.
The minimum mass of adults of the meat direction is 4.5-5 kg. The maximum weight of representatives of this species is 10-12 kg. On average, adult animals raised for meat grow to 6-7 kg. At the same time, at the age of three months, the live weight of the rabbit is approximately 40-45% of the weight of an adult individual, which is 2.5-2.7 kg.
Adult representatives of meat and downy breeds weigh on average 5 kg, reaching by three months approximately the same indicators as meat breeds - 2.5-2.7 kg.
Downy rocks are the easiest. Adults hardly reach 3.5-4 kg, in 3-4 months they barely reach 2 kg.
What can influence the mass growth rate?
There is a relationship between the time of year and the mass of animals. Rabbit leaders agreed that the time of birth influences the growth rate of the rabbit. It was noted that individuals born in the winter or at the beginning of spring develop much faster than those born in the summer-autumn period.
Different types of rabbit develop differently. But on average, from about 80 days of life, feed costs begin to increase significantly.
Therefore, it is recommended in most cases to complete the fattening process at about 3 months.
Representatives of absolutely all species of the hare family cease to grow, gaining maximum weight after 10 months. As a rule, only fertile females and males are kept up to that age. The rest of individuals cease to exist by 4 months.
How does rabbit milk growth affect
The growth rate of rabbits is affected by the milkiness of the female. If the rabbit has a high-quality milk in sufficient quantity, if it responsibly approaches the process of raising the offspring, then the intensity of the mass of the rabbits will be very high. And not only in the lactation period, but also after separation from the mother.
Summer okrol gives more complete milk to the rabbit than spring milk. In the first birth, the milkiness of the female will be lower than in the subsequent ones. The highest rates can be manifested only in the third lactation.
The best indicators of milkiness - in California breed and Soviet chinchilla. The worst - in New Zealand whites.
Dairy rabbits can be determined in comparison with other individuals of the species. Visually, females with better chest girth are larger by about 7%. And the torso is longer by 2% with a reduced body mass of 700-800 g.
The relationship between health and weight gain
An important factor for rapid weight gain is the health of rabbits. Physical data of eared differ from other types of agricultural animals. Normal harescent body temperature can vary from 37 to 41 degrees, falling in the winter and rising in the summer heat.
Pets of rabbit farms feel comfortable at an ambient temperature of 15 to 22 degrees. But they can withstand frosts up to -30, and heat +30 degrees.
Dampness and drafts can provoke diseases that adversely affect the growth of livestock. Therefore, provide your pet with acceptable living conditions, a balanced full-fledged diet, cleanliness in the cells and a calm psychological environment.
If all these conditions are met, eared health will be in order. They will quickly gain weight, and the cost of care and quality food will quickly meet your expectations. In the article "How many rabbits live" you will find all the details about the life expectancy of eared animals.
