The growth of rabbits in the suckling period and their further development in many respects depend on the milk yield of rabbits and biological value of milk.
DOE allocates the milk for 40-45 daysand , when compacted kindling 27-28 days. For 2-5 days prior to kindling the secretion of milk usually stops. During lactation, the DOE allocates up to 5 kg of milk, and the first four days is colostrum, which contains dry matter and 26.5%, protein — 11,5, fat — 11,9, ash — 1,5%.
Milk rabbit white, odorless, cream-looking consistency. Depending on the period of lactation, season of year and other factors the chemical composition of rabbit's milk varies, but on average, it contains (%), protein — 12,9, fat — 15, ash — 2.4 GHz, including calcium and 0.64, phosphorus — 0,44.
The secretion of milk during lactation is uneven. In the first two decades of DOE allocates up to 60% of the milk, and for the next two — 39-40%. After the 4th decade 70% of rabbit milk is practically absent, and the rest spend up to 20 g of milk per day, or 2-3 g per rabbit.
The average daily secretion of milk also varies during different periods of lactation. So, in the first week it is on average 129,6 g, the second — 176,9, in the third — 147,9 and fourth — 47,9 g.
Milking rabbits depends on many factors:
- the conditions of feeding,
- the season of the year,
- the period of lactation,
- of the breed of,
- age and number of breeding.
Peak milk yield of different rabbit 3rd and 4th kindling. Determination of the milk yield of rabbits, despite the complexity of accounting has important practical significance.
Maslomolochny and dairy rabbit differ from each other on the exterior. For dairy characterized by an elongated body, well-developed, strong bones, deep chest, thick, thin and elastic skin. Maslomolochny same inherent high live weight, compact, relatively shortened body, shallow chest and a strong development of the subcutaneous tissue.
On milk yield of rabbits are judged on appearance rabbitsthey as in the nest — liquor. Rabbits in dairy-rabbits are well developed, the skin is stretched, without wrinkles, hair shiny
Milking rabbits is determined, and the calculation method of based on the fact that rabbits until the 20th day consume only milk. In addition, it is established that the increase of 1 g of live weight consumed 2 g of milk.
Therefore, the amount of milk in 20 days can be determined by the formula:
M20 = (W2 – W1)*K
Where
M20 – milk rabbit in 20 days
W1 – the mass of the litter of newborn rabbits,
W2 – the live weight of litter at 21 days,
To – conversion factor live weight of young rabbits to rabbit milk.
Milk rabbit in 20 days of lactation is isolated from 3.2 to 3.5 g of milk.
