The price index of veterinary APIs was 63.17-63.26-63.43-63.53 respectively for the four weeks of this month, from August 7th to 28th. It indicates that the overall veterinary drug raw material market was stable this month, with some varieties fluctuating and adjusting. In the first half of the month, most categories, such as doxycycline hydrochloride and neomycin sulfate, showed oscillating adjustments; categories, such as florfenicol, amoxicillin, and doxycycline hydrochloride,...

Coccidiosis is a widespread parasitic disease that can seriously harm the livestock industry, especially affecting poultry and swine. This disease causes inflammation of the intestines, slower growth rates, and in severe cases, high mortality. In this article, we will discuss the causes, symptoms, and treatment options for...

1. Introduction Gut microbiota, represented by bacteria, archaea, viruses, and eukaryotes, take part in regulating several functions in both humans and animals [1]. It has been estimated that the chicken gut can be colonized by at least 1000 different microbial strains that are involved in maintaining the intestinal health of hens while sustaining productivity and growth [2,3]. This microbiota takes part in various metabolic pathways related to nutrient digestion and absorption,...

What many nutritionists do in LCF, is to create 2 nutrients for calcium. One might simply have the name calcium and would include the total amount of calcium in the ingredients plus the value assigned in the phytase matrix. To this nutrient it would be assigned the min and max restrictions and it would be used to calculate the Ca.avP ratio (which could receive the restrictions instead of calcium). The other nutrient is usually called something like analyzable calcium (or calcium lab) and would...

When building a new house or retrofitting an older one, tunnel fan selection is one of the most, if not the most important decision a producer has to make. A house’s fans are essentially the engine of the ventilation system and as a result have a significant effect on a producer’s ability to maintain the proper environmental conditions throughout the year. Furthermore, with rising electricity prices, selecting the right energy-efficient fan can save a producer thousands of...

1. Introduction The laying hen industry in the United States consists of approximately 330–340 million laying hens [1] that must first go through the growing phase known as the pullet phase. The pullet phase accounts for approximately 25% of a laying hen’s lifetime [2] and encompasses approximately 0–16 weeks of age (WOA). During this time, the pullet reaches sexual maturity and grows to its full skeletal capacity. Early experiences during the pullet phase,...

1. Introduction The increase in food demand driven by population growth, coupled with the reduction in the supply of raw materials owing to factors such as climate change, poses a significant challenge for the agricultural and livestock sectors. Among the different processes associated with egg production, the feeding of hens represents the largest source of environmental impact [1]. Nonetheless, the revaluation of agrifood by-products through their incorporation into animal diets...

1. Introduction Poultry refers to avian species (e.g., Gallus gallus domesticus—chicken; Anas platyrhynchos domesticus—duck) housed in a diversity of production systems (e.g., organic, free-range and conventional structures) that are dedicated to the production of poultry products, specifically chicken meat and table eggs for human consumption and eggs hatching for reproduction [1,2]. Bacterial contamination in poultry can be initiated by ingestion of contaminated feed or...

1. Introduction Avian metapneumovirus (aMPV) is a highly infective virus that affects turkeys and chickens, causing turkey rhinotracheitis (TRT) and swollen head syndrome (SHS), respectively. aMPV also has the capacity to infect other avian species [1–3]. The virus is primarily associated with upper respiratory infections, predisposing birds to opportunistic bacterial pathogens, which can result in severe respiratory disease, high morbidity, and mortality rates....

1. Introduction The Newcastle disease virus (NDV), a member of the Paramyxoviridae family, poses a global threat to poultry and wild birds due to its worldwide distribution and ability to infect various avian species [1]. Infection of birds with highly virulent strains of NDV results in immunosuppression, which at least in part results from profound depletion of lymphoid tissues [2,3]. NDV has also been extensively studied in human tumour cells for its potential role as...

1. Introduction S. Infantis currently ranks among the top 10 serovars associated with human infections, standing as the fourth leading cause of salmonellosis cases in the EU [1]. Recent data from the European Food Safety Authority (EFSA) indicated that 95.6% of the Salmonella isolates in broiler flocks belong to the Infantis serovar, demonstrating a close association with poultry production [2]. In recent years, the increasing incidence of S. Infantis infections in both humans...

Using evaporative cooling to keep birds cool during hot weather is relatively simple. Water is circulated over paper pads. Tunnel fans pull hot outside air through the pads and into the house. As the air moves through the wetted pads, its temperature decreases. Fairly straightforward. On the other hand, understanding how evaporative...

When designing a tunnel-ventilated house, it is important to install the proper amount of evaporative cooling pad. Too little pad will result in excessive static pressure, which will reduce air speed, and therefore bird cooling. Too much pad will result in increased initial cost, more pads to maintain/replace, and a larger area of reduced air movement near the tunnel inlet end wall. Pad area is based not on the size of a house but rather on the air-moving capacity of a house's...
