Embodiment 1

[0041] Embodiment 1 feeding pattern

[0042] In actual production, the limited feeding mode is usually used to ensure the best fertility of reproductive sows. However, excessive feed restriction makes sows feel unsatisfied during gestation, frequent stereotyped behaviors, insufficient nutritional supply, and intrauterine growth retardation, resulting in reduced reproductive performance of sows. Therefore, an appropriate feeding mode is the premise to ensure the high reproductive efficiency of sows. Previous studies divided the gestation period into early, middle and late stages and determined the feeding amount for each stage separately. However, recent research suggests that it is more necessary to determine the nutritional needs of the fetus and its contents in terms of their developmental window. Therefore, according to the developmental characteristics of the fetus and its uterine content, the present invention divides the gestation period of Guangdong Microtia sows into...

Embodiment 2

[0051] Example 2 Effect of feeding mode on farrowing performance of Guangdong small-eared piglets

[0052] In order to verify the effect of the present invention, the reproductive performance of Guangdong Microtia sows was compared between the stepped feeding pattern group and the concave pattern feeding pattern group.

[0053] 1. Experimental animals

[0054] The experimental animals were Guangdong small-eared pigs, and the experimental site was the Lemin core breeding pig farm of No. 1 Food Co., Ltd., Zhanjiang City, Guangdong Province.

[0055] 2. Test treatment and grouping

[0056] Select 80 Guangdong small-eared pigs with the same body weight and backfat, and divide them into 2 groups randomly, with 40 repetitions in each group, and 1 pig in each repetition. The first group adopts the ladder feeding mode in Example 1, the second Two groups adopt the concave feeding pattern among the embodiment 1. The daily feeding amount of the two groups was different from 1st to 85t...

Embodiment 3

[0072] Example 3 Effects of Feeding Patterns on the Muscle Weight of Guangdong Small-eared Pigs

[0073] 1. Test material

[0074] (1) Test animals

[0075] First-mated piglets born after crossing the female parent of Guangdong miniature pig with Duroc boar.

[0076] (2) Sample collection

[0077] On the day of sow farrowing, select 7 sows in the stepped feeding pattern group (the specific feeding method is the same as in Example 2), and 5 sows in the concave feeding pattern group (the specific feeding method is the same as in Example 2) (choose All sows were healthy sows with normal litter size, well-developed mammary glands), and 1 newborn piglet with average body weight and low body weight was selected for each sow in each group, totaling 24 piglets. The animals were weighed before feeding on colostrum, and then slaughtered on-site to collect samples. After slaughtering, the heart, liver, spleen, lung, kidney, small intestine, supraspinatus, infraspinatus, triceps brach...

Abstract

The invention belongs to the technical field of livestock breeding, and particularly relates to a Guangdong small-ear spotted pig gestation period feeding method for promoting development of offspringmuscle. According to the development characteristics of pig fetuses and uterus contents thereof, the Guangdong small-ear spotted sow gestation period is divided into six specific periods, and the feeding amounts of the six periods are determined respectively; meanwhile, two gestation materials in the early gestation period and the later gestation period are combined to replace a previous North America and domestic step-by-step mode and a European low-high-low-high feeding mode, and accurate feeding is implemented, so that the reproductive performance of sows is optimized. Related data supportand theoretical guidance are provided for establishing reasonable feeding amounts at different stages of the local pig gestation period in China.

Description

technical field [0001] The invention belongs to the technical field of livestock and poultry breeding, and in particular relates to a feeding method for Guangdong small-eared piglets during pregnancy for promoting the muscle development of offspring. Background technique [0002] In recent years, with the improvement of consumers' living standards, people's requirements for the quality of pork are also increasing. At present, the main group of domestic commercial pig breeding is the high-lean pig breeds imported from abroad and their hybrid offspring. Its advantages are fast growth, high carcass lean meat rate and feed conversion rate, but compared with local varieties in my country, the meat quality and stress resistance ability are significantly reduced. As a result, the pork of local pig breeds in China occupies an important position in the high-end brand pork in the international pork market. [0003] Guangdong small-eared pig is an excellent local pig breed in South C...
