Dividing fattening cattle into several stages for scientific rearing is one of the key technologies for beef fattening quickly. Now this technology is introduced as follows.
1. Observation period (10 to 15 days)
1) When cattle are purchased, they should be weighed, numbered, weighted and grouped, and weighed once a month and recorded.
(2) The day of purchase of cattle (12-24 hours) only drinking water (fresh water + salt), no fodder.
(3) Oral or injection of insects with insect killers 3 to 4 days after purchase.
(4) The zearalenol weight-increasing agent is injected 5 to 6 days after the purchase, and the cattle up to 3 months old are not injected.
5) In the first week of the purchase, no concentrate is given to the grass. The concentrate is given in the second week of purchase. However, if the feed is not given to the cake, the amount of feed should be gradually increased. The daily increase of the concentrate should not exceed 0.5 kg, gradually increasing. To 2 kg. Feed 2 times a day, feed 1 hour at a time, feed again at 8 hours intervals, drink 2 times a day, and drink water 1 hour after each feeding.
2. Adaptation period (10 to 20 days) In this period, concentrates are added to 3 kg in one week on the basis of 2 kg of cornmeal per head. The bean cake is given 0.25 kg per head per day. The ratio of refined material to coarse material is 40:60. In this period, the concentrate feed amount is 1 kg for each 100 kg of body weight. Feeding and drinking time, frequency and interval were the same as the observation period.
3. Pre-fattening (30 days)
After adjusting for the amount of feed, gradually increase the amount of forage, cornmeal, and cakes. This time, the amount of concentrate feed was increased by 10% on the basis of 1 kg of fine material per 100 kg of body weight. The ratio is 60:40. Each feeding time is 2 hours, the other with the adaptation period.
4. Late fattening (30-40 days)
On the basis of the previous period of fattening, we should gradually reduce the amount of roughage feed and increase the amount of concentrate feed, and add 15% on the basis of 100 kg of body weight to 1 kg of concentrate. The ratio of refined to coarse material is 70:30. Each feeding time is 2.5 hours, and other pre-fattening periods.
The garden pansy is a type of large-flowered hybrid plant cultivated as a garden flower. It is derived by hybridization from several species in the section Melanium ("the pansies") of the genusViola, particularly Viola tricolor, a wildflower of Europe and western Asia known as heartsease. Some of these hybrids are referred to as Viola wittrockiana Gams ex Nauenb. & Buttler. For simplicity, the older name Viola tricolor var. hortensis is often used.
The garden pansy flower is 5 to 8 centimetres (2 to 3 in) in diameter and has two slightly overlapping upper petals, two side petals, and a single bottom petal with a slight beard emanating from the flower's center. These petals are usually white or yellow, purplish, or blue. The plant may grow to 23 cm (9 in) in height, and prefers sun to varying degrees and well-draining soils.
