Problems solved by technology

[0004] At present, there is still no research on the use of vegetable oil, especially hemp oil, a specialty of Bama, Guangxi, to regulate the activity of hydrogenating bacteria in the rumen of buffalo, and then increase the content of unsaturated fatty acids, especially conjugated linoleic acid (CLA) in milk buffalo milk fat.

Embodiment 1

[0023] Embodiment 1: Feed of the present invention

[0024] Add 100g / d and 200g / d hemp oil respectively to the concentrated material of the basic diet of the present invention, and mix with coarse material to obtain the feed described in the present invention.

[0025] The hemp oil used in the present invention is made by pressing the hemp seeds purchased from Bama, Guangxi, and the obtained hemp oil fatty acid contains the following components in mass percentage: 10.226% of saturated fatty acid and 89.774% of unsaturated fatty acid.

[0026] The hemp oil fatty acid contains the following mass percentage components: fatty acid C14:0 0.012%, fatty acid C16:0 6.301%, fatty acid C16:1n7 0.094%, fatty acid C18:0 2.918%, fatty acid C18:1n9t0.001%, fatty acid C18 :1n11t 0.021%, fatty acid C18:1n9c 10.238%, fatty acid C18:2n6c 58.321%, fatty acid C18:3n6 0.476%, fatty acid C20:0 0.769%, fatty acid C18:3n3 20.243%, fatty acid C18:2n9c 0.365%, fatty acid C22 :0 0.226%, fatty acid C20:...

Embodiment 2

[0031] Embodiment 2 adopts feed described in the present invention to carry out comparative feeding experiment to milk buffalo

[0032] 1. Test process

[0033] 1.1 Test material

[0034] Hemp oil is obtained by squeezing the hemp seeds purchased in Bama, Guangxi. According to Zhang Chunmei (2008) to the determination method of vegetable oil, the fatty acid composition of hemp oil is as shown in Table 1.

[0035] Table 1 hemp oil fatty acid composition (%)

[0036]

[0037]

[0038] 1.2 Experimental animals and feeding management

[0039] Test location: Cowhouse 1, Cattle Farm, Breeding Demonstration Research Base, Guangxi Buffalo Research Institute, Chinese Academy of Agricultural Sciences

[0040] Experimental animals: 18 buffaloes with three-grade mixed milk (local buffalo x Niri-Rafi buffalo x Mora buffalo)

[0041] Test time: May 18, 2014 - June 28, 2014

[0042] Feeding management: Cattle are under the responsibility of a special person, fed in a single trough ...

Abstract

The present invention provides a milk buffalo feed which is manufactured by adding 100 g / d-200 g / d of cannabis sativa oil into the refined grain of the basic daily ration. The present invention also provides a method for improving milk buffalo breeding, which uses the feed to feed the milk buffalos. The provided feed and breeding method can effectively improve the polyunsaturated fatty acid content of the buffalo milk produced by the milk buffalos without affecting the growth performance of the milk buffalos.

Description

【Technical field】 [0001] The invention belongs to the technical field of breeding, and in particular relates to a feed and a feeding method for milk buffaloes. 【Background technique】 [0002] Hemp oil is known as "the most valuable vegetable oil". Its unsaturated fatty acid content is the highest among all vegetable oils, and it is the only oil in nature that can dissolve in water. Freshly extracted hemp oil has a special fragrance of hemp seeds, and it is a yellow-green translucent oily liquid at room temperature, and it turns yellow-brown after a long time. Refractive index (1.48) and relative density (0.92) of hemp oil are lower than other vegetable oils, acid value (KOH) is less than 3mg / g, peroxide value is less than 6mmol / kg, iodine value is 140-170 (usually 150-160), It is a drying oil. [0003] At present, a total of 29 compounds have been identified in hemp oil, of which fatty acids account for 99.12% of the total content, and 18 compounds have been identified. I...
