2023 layer chicken industry boom recovery, unstoppable

2023 layer chicken industry boom recovery, unstoppable

In 2023, the total number of laying hens will be slightly higher than the 2022 forecast, the stock structure is expected to be the opposite of 2022, the proportion of young and middle-aged high-yield laying hens has increased, the proportion of old chickens has decreased.

The Ministry of Agriculture and Rural Affairs issued the "Technical Guidance for Animal Husbandry to Deal with Cold Wave and Blizzard Weather"

The cold wave in many places has arrived. From November 27, the temperature in most parts of northern and central and eastern China will drop by 10 ℃ to 16 ℃, and the temperature drop in some areas can reach more than 18 ℃. In order to cope with the possible impact of large-scale and large-scale cooling on animal husbandry, on November 30, the Ministry of Agriculture and Rural Affairs issued the "Technical Guidance for Animal Husbandry to Deal with Cold Wave and Blizzard Weather", the full text is as follows.

2030 feed grain consumption demand will also increase soybean meal reduction into a breakthrough in agricultural efficiency

2030 feed grain consumption demand will also increase soybean meal reduction into a breakthrough in agricultural efficiency

Soybean meal reduction substitution is of great significance for farmers to save costs, feed producers to save materials, industry-wide efficiency and national food security. It is necessary to make use of the achievements of modern animal nutrition, take the reduction and substitution of soybean meal as a breakthrough, fully tap agricultural resources, and improve the quality and efficiency of agriculture. To promote the reduction and substitution of soybean meal, we should not only change the traditional concept, but also bring it into the category of ecological product value compensation mechanism.

Break through the 5200 yuan/ton mark! Soybean meal prices hit nearly a decade high, crazy rally to when?

Break through the 5200 yuan/ton mark! Soybean meal prices hit nearly a decade high, crazy rally to when?

This year, spot soybean meal prices have risen 23.7 percent year-on-year. Since mid-August, the domestic downstream industry's National Day stocking market has started, and the spot price of soybean meal has continued to rise. The price in some areas has exceeded the 5200 yuan/ton mark, setting a new high in the past 10 years.

Effects of early intervention of Clostridium butyricum on intestinal flora and short chain fatty acids in broilers

Effects of early intervention of Clostridium butyricum on intestinal flora and short chain fatty acids in broilers

This experiment was conducted to study the effects of early intervention of Clostridium butyricum (Clostridium butyricum) on intestinal short-chain fatty acids (SFAs) and flora structure of Enterotoxigenic Escherichia coli (ETEC) in broilers. 200 1-day-old ROSS broilers were selected and divided into two groups, 100 in each group. Three days before the experiment, one group was fed with 1mL of Clostridium butyricum with a concentration of 109 CFU/mL every day, and the other group was fed with 1mL of normal saline. At 7 days of age, broilers fed with saline were divided into control group (Control) and E. coli group (EC). Broilers fed with Clostridium butyricum were divided into Clostridium butyricum group (CB) and Clostridium butyricum E. coli group (CB EC). From the age of 7 days to the end of the experiment, EC group and CB EC group were fed with 1mL(108 CFU/mL) enterotoxigenic E. coli solution for challenge, while Control group and CB group were fed with 1mL normal saline. Slaughter sampling at 3d and 7d after ETEC challenge. The results showed that: ① In the caecum of broilers, at the age of 10 days, compared with the Control group, the acetic acid content in CB group was significantly increased (P<0.01), and the acetic acid content in EC group was significantly decreased (P<0.05). The content of butyric acid in CB group and CB EC group is relatively similar, and is significantly higher than that in Control group and EC group (P<0.01). At 14 days of age, compared with Control group, the contents of acetic acid, propionic acid, butyric acid and isobutyric acid in CB group were significantly increased (P<0.05), while those in EC group were significantly decreased (P<0.05). ②At the age of 10 days, in the CB group, the relative abundance of rumen cocci was the highest, which was significantly higher than that of the other experimental groups (P<0.05). It can be seen that the early intervention of Clostridium butyricum in broilers can promote the production of intestinal short-chain fatty acids and improve the structure of cecal flora to a certain extent. The full text has been published in the 11th issue of Feed Industry in 2021.

One article to take you to quickly understand the poultry heat stress!

One article to take you to quickly understand the poultry heat stress!

Heat stress is the sum of non-specific responses of humans or animals to stimuli that exceed their own thermoregulatory capacity. The chicken is a warm-blooded animal with its own isothermal zone. The comfort zone of laying hens is 13 ℃ ~ 27 ℃, and the ambient temperature of maximum feed efficiency is 24 ℃ ~ 27 ℃. The maximum growth rate of broilers is 10 ℃ ~ 22 ℃, and the best feed efficiency is 27 ℃.
