Embodiment 2

[0050] Example 2 Effect of Cotton Straw Compound Pellet Feed on Production Performance and Reproductive Performance of Ewes

[0051] In the experiment, 120 small-tailed Han sheep ewes who were 7 months old, first born, weighed close to (42.29±6.11) kg, and in good body condition were selected for feeding experiment with cotton stalk and pellet feed. 6 groups, 20 rats in each group (n=20). Among them, control group 1 (CK1 group) did not contain cotton source feed (does not contain cotton stalks and cottonseed meal), and control group 2 (CK2 group) contained cottonseed meal and did not contain cotton stalks. 20%, 30%, 40% and 50% cotton stalks were added to the diets of other sub-test groups. The experiment lasted 240 days from the beginning of the pre-trial period to the end of delivery. The experimental sheep were kept in the breeding pen in the same environment, and they were divided into groups to eat and drink freely. They were fed twice a day at 09:00 and 19:30, and kept...

Abstract

The invention provides a sheep series pellet feed, and a preparation method and application thereof, and belongs to the technical field of animal production feed processing. The sheep series pellet feed includes individually-packed backup sheep feed, fattening period sheep feed, sheep feed in the first half period of gestation, and sheep feed in the latter half of gestation. According to the nutritional requirements of sheep at different physiological stages, cotton straw is combined with energy feed, protein feed, vitamins, trace elements and other feeds respectively and prepared into the pellet feed. The sheep series pellet feed is good in palatability, the free gossypol content is low, homogeneity is good, the sheep can be prevented from being picky eaters, feed intake is increased, feed loss and waste are effectively reduced, and digestibility and utilization of the feed are improved. According to the sheep series pellet feed, the unit cost of the daily ration the sheep can be significantly lowered, and the normal functioning of the production performance of the sheep and meat quality of mutton are guaranteed.

Description

technical field [0001] The invention relates to the technical field of animal husbandry feed processing, in particular to a series of sheep pellet feed and its preparation method and application. Background technique [0002] Cotton is one of the economic crops grown in my country's agricultural production areas. The mass fractions of crude protein, cellulose, hemicellulose and lignin in cotton straw are 6.5%, 44.0%, 10.7% and 15.2%, respectively. As one of the crop straws with huge reserves, it has the potential to be used as roughage for ruminants. However, the current methods of cotton straw utilization are mainly returning to the field, grazing in the field, and direct burning, and the feed utilization rate is less than one-third of that of other crop straws. If the utilization rate of cotton stalks increases by 1 percentage point, it can meet the annual forage demand of 202,600 sheep units, and the feed utilization of cotton stalks can provide a huge source of roughage...
