    有關(guān)長毛兔飼養(yǎng)管理的四個要點

    發(fā)布日期:2023-02-25 來源:http://www.whxfy.cn 發(fā)布人:admin

    有關(guān)長毛兔飼養(yǎng)管理的問題,必須加以高度關(guān)注,這也是為了讓您更好的飼養(yǎng)長毛兔,達到好的效果。下面來分析一下吧。
    We must pay close attention to the issue of raising and management of long-haired rabbits, which is also to make you better raise long-haired rabbits and achieve good results. Let's analyze it.
    一、飼料要富含蛋白質(zhì)
    1、 Feed should be rich in protein
    長毛兔的飼料組成上一定要有較高的蛋白水平。據(jù)估算,毛兔每產(chǎn)毛1千克,相當(dāng)于肉兔產(chǎn)肉7千克消耗的蛋白質(zhì)。同時,其他營養(yǎng)如能量、纖維素、礦物質(zhì)和維生素等,必須保持平衡。在蛋白質(zhì)中,要有促進兔毛生長的含硫氨基酸——蛋氨酸和骯氨酸。
    The feed composition of long-haired rabbits must have a high protein level. It is estimated that each kilogram of wool produced by wool rabbits is equivalent to 7kg of protein consumed by meat rabbits. At the same time, other nutrients such as energy, fiber, minerals and vitamins must be balanced. In the protein, there should be sulfur-containing amino acids, methionine and arginine, which promote the growth of rabbit hair.
    為了提高產(chǎn)毛量和兔毛質(zhì)量,可在飼料中添加含硫物質(zhì)和促進兔毛生長的生理活性物質(zhì),如稀土添加劑、松針粉、蠶砂、硫磺、膽堿和甜菜堿等。
    In order to improve the wool yield and the quality of rabbit hair, sulfur substances and physiological active substances that promote the growth of rabbit hair can be added to the feed, such as rare earth additives, pine needle powder, silkworm excrement, sulfur, choline and betaine.
    二、營養(yǎng)供應(yīng)要有階段性
    2、 Nutrition supply should be phased
    營養(yǎng)的階段性是指毛兔剪毛前后環(huán)境發(fā)生了很大變化,因而營養(yǎng)要求適應(yīng)這種變化的需要。尤其是在較寒冷的季節(jié),剪毛后突然失去了厚厚的保溫層,維持體溫要求較多的能量。同時,剪毛可刺激兔毛生長,需要大量的蛋白質(zhì)。
    The stage of nutrition refers to the great changes in the environment of wool rabbits before and after shearing, so the nutrition requirements adapt to the needs of this change. Especially in the colder season, the thick insulation layer is suddenly lost after shearing, which requires more energy to maintain body temperature. At the same time, shearing can stimulate the growth of rabbit hair, which requires a lot of excellent protein.
    因此,在剪毛后3周內(nèi),飼料中的能量和蛋白質(zhì)水平需要適當(dāng)?shù)靥岣撸曃沽恳矐?yīng)有所增加,或者采取自由來食的方式,以促進兔毛的生長。
    Therefore, within 3 weeks after shearing, the level of energy and protein in the feed should be appropriately increased, and the feeding amount should also be increased, or the way of free feeding should be adopted to promote the growth of rabbit hair.

    三、抓早期增重
    3、 Grasp early weight gain
    加強早期營養(yǎng)可以促進毛囊的分化,提高被毛密度,同時增加體重和皮表面積,這是養(yǎng)好毛兔的關(guān)鍵措施。一般掌握從斷乳到3月齡階段應(yīng)以較高營養(yǎng)水平的飼料飼喂。
    Strengthening early nutrition can promote the differentiation of hair follicles, improve the density of hair, and increase body weight and skin surface area, which is the key measure to raise wool rabbits. It is generally understood that from weaning to the age of 3 months, it should be fed with feed with higher nutritional level.
    四、注意控制體重
    4、 Pay attention to weight control
    盡管體重越大產(chǎn)毛面積越大,產(chǎn)毛也越多,但是,體重并非越大越好,過大的體重產(chǎn)毛效率低,即用于產(chǎn)毛的營養(yǎng)與維持營養(yǎng)的比例小,利用時間短,所以體重一般應(yīng)控制在4~4.5千克為好。營養(yǎng)水平采取前促后控的原則:一般掌握能量降低5%,蛋白質(zhì)降低1個百分點,保持氨基鼓水平不變;也可以采取控制采食量的辦法,即提供自由采食量的85%~90%,而營養(yǎng)水平保持不變。
    Although the larger the weight is, the larger the area of wool production is, the more wool production is. However, the larger the weight is, the lower the efficiency of wool production is. That is, the proportion of nutrition used for wool production and maintenance is small, and the utilization time is short. Therefore, the weight should be controlled at 4~4.5 kg generally. The principle of promoting the nutrition level before and controlling the nutrition level after: generally, reduce energy by 5%, protein by 1 percentage point, and keep the amino drum level unchanged; It is also possible to control the intake, that is, to provide 85% - 90% of the free intake, while the nutrition level remains unchanged.
