Benefits of technology

This patented technology helps prevent or reduce problems caused from excessive use of antimicrobic agents like amoxycin during animal husbandry operations due to their ability to kill harmful microorganisms that may be causing diseases on fishes' eggs. By incorporating certain ingredients into this feeds containing these specific strains, it becomes possible to increase the efficiency at raising flockers while reducing negative side reactions associated therewith. These added components are also beneficial because they help maintain good fertilization rates when fed onto seafood crops without affecting them negatively impacted upon human consumption.

Problems solved by technology

The technical problem addressed in this patented text relates to finding ways to enhance animal health through use of beneficial substances like probiostats or other bioplasms (prokiting bacteria) which help maintain gut floral equilibrium while promoting egg-quality improvement over current methods.

Embodiment 1

[0020] 120 Hailan brown layer hens (middle and late stage of egg production peak period) were randomly divided into control group and three lactobacillus feeding groups (Lactobacillus salivarius group, Lactobacillus agility group, saliva + Lactobacillus agility mixed group), each 30 feathers in the group were fed with conventional feed and corresponding Lactobacillus (10 8 CFU / chicken / day), continuous feed for 30 days. During the feeding experiment, the number of eggs laid in each test group was counted every day.

[0021] Statistical results on egg production rate ( figure 1 ) showed that the daily egg production rate of the saliva+Lactobacillus agili mixed group was higher than that of the control group on 19 days within 30 days (3.57%-16.67% higher). The analysis results of the egg production rate of the month (Table 1) showed that the egg production rate of the mixed group of saliva+Lactobacillus facilis was 2.96% higher than that of the control group.

Embodiment 2

[0025] 120 Hailan brown layer hens (middle and late stage of egg production peak period) were randomly divided into control group and three lactobacillus feeding groups (Lactobacillus salivarius group, Lactobacillus agility group, saliva + Lactobacillus agility mixed group), each 30 feathers in the group were fed with conventional feed and corresponding Lactobacillus (10 8 CFU / chicken / day), continuous feed for 30 days. During the feeding trial, the eggs of each test group were weighed daily.

[0026] The analysis results of single egg weight ( figure 2 ) showed that the daily average single egg weight of the saliva + Lactobacillus agili mixed group was higher than that of the control group on 21 days within 30 days (0.05%-6.65% higher). The analysis results of the average single egg weight and total egg weight of the current month (Table 2) show that the average single egg weight of the mixed group of saliva + Lactobacillus agili is 1.34% higher than that of the control gro...

Embodiment 3

[0030] 120 Hailan brown layer hens (middle and late stage of egg production peak period) were randomly divided into control group and three lactobacillus feeding groups (Lactobacillus salivarius group, Lactobacillus agility group, saliva + Lactobacillus agility mixed group), each 30 feathers in the group were fed with conventional feed and corresponding Lactobacillus (10 8 CFU / chicken / day), continuous feed for 30 days. On the 30th day of the feeding experiment, 20 eggs were randomly collected from each group, and the eggshell thickness was measured at the tip, equator and blunt end of the eggs.

[0031] The statistical results of eggshell thickness ( image 3 ) showed that, compared with the control group, the eggshell thickness of the saliva+Lactobacillus agility mixed group increased by 27.3%, 20.7% and 16.9% at the tip, equator and blunt end, respectively.

Abstract

The invention discloses an additive for improving the laying rate and the egg quality of laying hens as well as preparation and application. The additive is a lactobacillus combination, and the lactobacillus combination is formed by combining lactobacillus salivarius and lactobacillus agilis in a volume ratio of 1:1. According to the additive, the lactobacillus salivarius and lactobacillus agiliscombination in a proper proportion is added into conventional laying hen feed, so that the laying rate and the egg quality of the laying hens are improved. The feed additive provided by the inventionhas the characteristics of safety, no toxicity, no harm and no residue, ensures the laying rate and the egg quality of the laying hens, can effectively alleviate the problem of abuse of antibiotics inthe breeding industry, provides a healthy green food for people, and has a wide market application prospect.
