Embodiment 1

[0024] Embodiment 1: A kind of diet with low phosphorus concentration, its composition and weight are listed in Table 1.

[0025] Table 1. Feed components and their weight (unit: % dry matter)

[0026]

[0027] Each kilogram of premix (without phosphorus) contains vitamin A 240000IU, vitamin D 60000IU, vitamin E 1200IU, zinc 2940mg, selenium 21mg, iodine 38mg, cobalt 8mg, manganese 630mg, copper 630mg, nicotinamide 400mg, and the rest are carrier Zeolite powder.

[0028] Animal experiment: test animal is healthy 8 to 10 month old Holstein back-up milk cows 15, feeds the ration of embodiment 1, and test cow adopts tethered feeding, drinks water ad libitum, feeds 3 times every day (each feed The dosage is the diet containing "2.4 kg (fresh weight) concentrate feed" above). The test period was 9 weeks (including a one-week pre-feeding period), in which feed samples, feces and urine samples, blood samples, etc. were collected in the 1st, 4th, and 8th weeks, and stored in a re...

Abstract

The invention discloses a reserve cow feed with low-phosphorous emission. The reserve cow feed comprises the following components in parts by weight: 25-26 parts of silo corn, 39-40 parts of chinese wildrye, 13.5-14.5 parts of corn, 6.0-6.5 parts of barley, 1.5-2 parts of bean meal, 4.5-5 parts of rapeseed dreg meal, 4.5-5 parts of DDGS, 0.5-1 part of phaseolin polypeptide and 2.3-2.8 parts of a non-phosphorus premix. The non-phosphorus premix per kilogram contains vitamin A, vitamin D, vitamin E, zinc, selenium, iodine, cobalt, manganese, copper, nicotinamide, and the balance being zeolite powder. At the premise of not affecting the growth performance of reserve cow, the feed can be used for reducing the concentration of dietary phosphorus, and reducing the emission of excrement and urea phosphorous, so that the pollution of a phosphorus element to the environment is reduced.

Description

technical field [0001] The invention relates to the field of dairy cow feed, in particular to a low-phosphorus-emission back-up cow feed, in particular to a feed for reducing back-up cow manure and urine phosphorus emissions by reducing the phosphorus concentration in the diet. Background technique [0002] With the rapid development of large-scale and standardized breeding, the waste produced by livestock and poultry has an increasing impact on the environment, among which the pollution caused by nitrogen and phosphorus discharge is particularly prominent. Studies have shown that ruminant phosphorus discharge accounts for 60% of total excretion. At present, due to the long cycle of producing benefits for heifers and low attention, there are relatively few studies on the dietary phosphorus requirements of heifers. In production, in order to ensure the normal growth and development of back-up dairy cows, excessive phosphorus is often fed. Studies have shown that excessive f...
