Formula feed for enhancing immunity of laying hens

Abstract

The invention discloses a formula feed for enhancing the immunity of laying hens. The formula feed is prepared from the following raw materials in parts by weight: 70-100 parts of corn, 10-20 parts ofsoybean, 5-8 parts of soluble calcium agent, 4-8 parts of Bupleurum tenue, 3-7 parts of radix isatidis, 3-7 parts of radix puerariae, 8-12 parts of houttuynia cordata, 3-7 parts of gynostemma pentaphyllum, and 4-6 parts of orange peel. The preparation method comprises the following steps: (1) weighing the raw materials according to the above weight part number, crushing the corn, soybean and soluble calcium agent, conducting sieving by a 150-200 mesh sieve to obtain a powder I; (2) mixing the Bupleurum tenue, radix isatidis, radix puerariae, houttuynia cordata, gynostemma pentaphyllum and orange peel weighed according to the weight part number, then adding water for decocting for 1 to 3 hours for 2 to 3 times, conducting filtration, concentrating the filtrate under reduced pressure to form an extractum, conducting freeze drying on the extractum and residue obtained after the filtration, then conducting pulverizing, and conducting sieving by a 150-200 mesh sieve, so as to obtain a powder II; and (3) uniformly mixing the powder I in the step (1) and the powder II in the step (2) under stirring. The feed can enhance the disease resistance and antibacterial ability of the laying hensand improve the immunity of the laying hens.

Description

technical field [0001] The invention relates to the field of livestock and poultry feed, in particular to a formula feed for enhancing the immunity of laying hens. Background technique [0002] Chicken is a common and important ingredient in daily life. Whether it is steamed, stewed, stewed, marinated or stir-fried, it has unique delicacy and excellent therapeutic and health value. Due to the large market demand, the current supply of chicken meat mainly depends on chicken farms. Chicken farms have mature breeding technology, and laying hens grow fast and benefit significantly. [0003] However, due to the high degree of intensification of the breeding process, there are problems such as high morbidity in chicken flocks. Especially in recent years, the prevalence of bird flu and chicken plague has brought huge challenges to the breeding industry. The main reason is that in the normal breeding process, we blindly pay attention to the weight gain rate and adopt duck-feeding ...

AI Technical Summary

Problems solved by technology

The main reason is that in the normal breeding process, we blindly pay attention to the weight gain rate and adopt duck-feeding feeding, do not pay attention to the physical condition of the chicken flock, and do not pay much attention to the immune resistance of the chicken flock, which leads to the resistance of the raised layer hens. In the face of bird flu or chicken plague outbreaks, chickens have no resistance, resulting in serious economic losses

[0004] In addition, in the process of modern livestock and poultry farming, in order to prevent and treat livestock and poultry diseases, excessive antibiotic products are often used to ensure the health of livestock and poultry, but the excessive use of antibiotics often leads to the decline in the quality of animal meat products and their products and the enhancement of antibiotic resistance. Transmission through the food chain leading to human health is also severely affected by the antibiotic problem
