Weaning lamb whole fat fast fattening
2021-07-06 13:06:12
Fast fattening of lambs for weaning lambs is divided into two categories: common feeding troughs and automatic feeding troughs. The former uses separate concentrates and coarse feeds, while the latter mixes fine and coarse feeds. . In order to reduce feed wastage, it is recommended that large and medium-sized intensive mutton farms use automatic feeders and use coarse-grained rations. Therefore, only automatic feeder rations are introduced here.
Diet formulation now introduces four feed formulations. The first two are medium energy levels and the last two are low energy levels. For production reference:
Formula 1 corn 58.75%, hay 40%, soybean cake 1.25%, plus antibiotic 1%. The formula dry food contained 11.37% of crude protein, 67.1% of total digestive nutrients, 0.46% of calcium, 0.26% of phosphorus, and an aspect ratio of 60:40.
Formula 2 Whole plant corn 65%, hay 20%, protein supplement 10%, molasses 5%. In this formula, protein supplements consist of 50% soybean cake, 33% bran, 5% thin molasses, 3% urea, 3% limestone powder, 5% calcium hydrogen phosphate, and 1% trace elements plus salt. In addition, add 33,000 international units of vitamin A, 300 units of vitamin D3, and vitamin E330 international units per kilogram of supplements. The dried feed of the formula contains 11.12% of crude protein, 66.9% of total digestive nutrients, 0.61% of calcium, and 0.36% of phosphorus, and the ratio of crude to crude is 67:33.
Formula 3 corn grain 53%, hay 47%, plus antibiotic 0.75%. The dry diet of this formula contained 11.29% of crude protein, 64.9% of total digestive nutrients, 0.61% of calcium, and 0.36% of phosphorus. The ratio of crude to crude was 53:47.
Formula 4 Whole plant corn 58.75%, hay 28.75%, protein supplement 7.5%, molasses 5%. Among them, the protein supplement composition is the same as Formulation II. The dried feed of this formula contains 11% of crude protein, 64% of total digestive nutrients, 6.4% of calcium, 0.32% of phosphorus, and a crude/crude ratio of 59:41.
The key points for management should be that legume-grass should be dominated by hay, and its crude protein content should be no less than 14%. The formulated diet should be consistent in color, especially the eared corn must be crushed, and it is difficult for the lamb to pick out from it. Corn kernels prevail. In accordance with the principle of gradual change, let the lamb gradually transferred to the full amount of fattening diet, the daily amount of each lamb lambs calculated according to 1.5 kg. Using the characteristics of labor-saving and labor-saving automatic feeders, feed once a day, that is, put a full-day dosage in the automatic feeding tank. It should be noted that the number of feeders should be appropriate.
The self-made method uses a suitable iron barrel (such as a gasoline barrel), removes the bottom of the upper cover, and welds four fine steel circular ring brackets on the bottom. The iron barrel is perforated on the upper 1/3 and a 1.5 meter long iron pipe is inserted. With two pieces of wood board fixed at the bottom of the trough on both sides, the upper end slot, groove diameter and iron pipe thickness consistent; then iron bucket on the trough on the chassis, feed poured into the iron bucket, will automatically fall, overflow.

RFID UHF Handheld Readers are the perfect, economical choice for when it's more practical to bring the read/write device to the tagged object rather than moving objects past a fixed reader. Handheld RFID is also ideal for use in the field for asset tracking, field service applications, and use by mobile workers.
