Embodiment 1

[0015] In May 2017, the experiment was carried out in the practical teaching base of Jinshan College of Fujian Agriculture and Forestry University. Test material is white-feathered broiler chicken, feeds the feed that contains curcumin [purity 93.5%] and bamboo powder carbon powder, namely the feed formula of the present invention (table 1 and 2), and white-feather broiler 25 days old begins to feed the formula of the present invention, feed The addition is concentrated in the big chicken stage, and the big chicken stage time is from 27-42 days old. During the period of 26-35 days, feed 5 times a day, the first feeding time is 5:00 am, and the interval is 4 hours. During this period, 21:00-22:00 is the dark time when the lights are turned off, and the fifth time is fed after turning on the lights. 36-42 days old are fed 5 times a day, the first feeding time is 5:00am, and the interval is 4.5 hours. The white-feathered broilers were weighed at the age of 35 days, and weighed c...

Embodiment 2

[0023] To study the effect of curcumin [purity 93.5%] and bamboo powder carbon powder on the body weight of broilers; broiler chickens in group A were fed without curcumin and bamboo powder carbon powder (control group); broiler chickens in group B were fed with curcumin [purity 93.5% %] (0.2wt%) and bamboo dust carbon powder (0.3wt%) formula; group C broilers were fed with curcumin [purity 93.5%] (0.5wt%) and bamboo dust carbon powder (0.5wt%) formula, table 1 shows; Group D broiler chickens are fed with a formula containing curcumin [purity 93.5%] (1.0wt%) and bamboo powder carbon powder (1.0wt%); wherein the feeding methods of each group are the same as in Example 1.

Abstract

The invention belongs to the technical field of chicken feed, and in particular to a feed formula for increasing the weight of broiler chickens in the large chicken stage and reducing the fat contentof the broiler chickens and a feeding method. The feed formula comprises the following raw materials according to mass fractions: domestic corn with the protein content of 7.8%, 3-grade soybean meal,curcumin with the purity of 93.5%, bamboo chip charcoal powder, yellow flour, 2-grade rice bran, stone powder, calcium hydrogen phosphate, L-lysine hydrochloride, premix, feather meal, corn gluten meal with the protein content of greater than or equal to 60%, lard oil and salt, wherein the sum of the mass fractions is 100%. The feed formula disclosed by the invention has the advantages that that 0.5wt% of bamboo chip charcoal powder and 0.5wt% of curcumin are added in the feed and the feed formula mainly concentrates on the large chicken stage; and therefore, the fat content of the broiler chickens can be effectively changed, the feed conversion ratio is increased and the marketing weight of the broiler chickens is increased.

Description

technical field [0001] The invention belongs to the technical field of chicken feed, and in particular relates to a feed formula and a feeding method for increasing the weight of broiler chickens at the big chicken stage and reducing the fat content of broiler chickens. Background technique [0002] With the rapid development of China's fast food industry, the consumption of chicken is increasing year by year, and chicken is delicious and nutritious. Chicken is one of people's favorite foods. It is loved by people for its low price and delicious taste. As the main source of chicken, broiler chickens are raised in large quantities. Broiler chickens are different from laying hens. Broiler chickens are mainly measured by body weight. The same feeding time and Feed amount, the greater the body weight, the higher the benefit. At present, the feed for broiler chickens is mostly supplemented with components containing various nutrients to provide nutrition. At present, in broiler c...
