Lodge series nutritious licking bricks are rich in mineral trace elements such as "phosphorus, calcium, zinc, magnesium, iron, cobalt, iodine, manganese, selenium, sodium", etc., which are freely supplemented for individuals in the flock, and finally achieve the balance of microminerals in the flock, improve the feed conversion rate, solve pica, and bring sustainable health to the flock.
The determination of lamb weaning time is a problem that modern and large-scale sheep raising must face and pay attention. Early weaning, lamb stress response is obvious, the performance of disease resistance decreased, the incidence rate increased. Weaning is too late, so that the ewe fat is poor, the utilization rate is reduced, increasing the cost of breeding. Lamb weaning is mainly based on the milk yield of the ewe, the physiological development of the lamb and so on.
(1) After lambing, the ewe reached the peak of lactation in 2-4 weeks, and the lactation in 3 weeks was equivalent to 75% of the total lactation in the whole period. After that, the lactation decreased significantly. Therefore, the breast milk nutrients secreted by the ewe after 60 days of age could not meet the nutritional needs of the rapid growth and development of the lamb.
.....................................................
(2) the rumen development of lambs can be divided into: the non ruminant stage from birth to 3 weeks of age, the transitional stage of 3 to 8 weeks of age and the ruminant stage after 8 weeks of age.
Studies have shown that lambs can slowly digest plant feed after 3 weeks of age, and maltase activity is gradually shown at 7 weeks of age,
The highest level of pancreatic lipase activity at 8 weeks of age allows lambs to utilize whole milk, at which point the rumen is fully developed and able to feed and digest large amounts of plant-based feed.
Therefore, the theory that early weaning at 8 weeks of age is more reasonable. However, some tests have shown that the lamb 40 days of weaning does not affect its growth and development, and the effect is not significantly different from the regular 3-4 months of weaning. There are also 45-50d weaning after birth, feeding plant feed or grazing in high-quality artificial grassland after weaning.
(3) Lambs early intake of feed and other plant feed, can promote the lamb digestive organs, especially the development of the rumen, promote the lamb early forage ability, improve the lamb in the later cultivation of feed intake and roughage utilization rate, at the same time can establish the dynamic balance of digestion and metabolism in the rumen of lamb.Taking into account, it is considered that lambs are suitable for weaning at 48-56 days, or when the live weight of lambs increases to 2.5 times the newborn weight.
