Dropping moisture (DM) refers to the water content in feces. High DM negatively affects poultry production, environment, production costs, and animal health. Heredity, nutrition, environment, and disease may affect DM level. DM has medium inheritability and is related to cage height in henhouses. We examined the relationship among DM level, production performance, and environmental factors at different locations at the same henhouse height and effects of three types of additives. We measured the correlation between environmental factors including temperature, humidity, CO2 concentration, absolute pressure, and DM levels and laying performance of 934 Rhode Island Red hens. DM level was not significantly associated with environmental factors or production performance. We divided 64 persistently high DM hens into control and treatment groups supplied with different additives (probiotics, anisodamine, and antibiotics). DM levels, laying performance, egg quality, and serum biochemical indices were determined. Compared with the control and antibiotics, probiotics significantly reduced DM levels and eggshell strength while improving yolk color but did not significantly affect production performance. The additives reduced the b value of eggshell color; compared with probiotics, anisodamine decreased serum globulin levels. Exogenous active yeast supplementation can significantly reduce DM levels.

Inflammatory Processes

In the course of the study permeability of intestinal mucosa of chickens suffering from eimeriosis while treating them with various veterinary drugs, including probiotics, was evaluated. The simulation of a typical clinical picture of eimeriosis was carried out by oral administration of suspension with coccidial oocysts (1.6 × 105/head) using a probe. To create different forms and different intensity of inflammatory processes, chickens that received various anticoccidial preparations and probiotic strain Bacillus subtilis were infected with eimeria. According to the data from an autopsy, it was found that the use of a spore probiotic based on Bacillus subtilis and anticoccidial drugs containing robenidine hydrochloride and salinomycin had a positive protective effect when treating chickens from eimeriosis. A similar picture was observed when assessing permeability of intestinal mucosa as affected by bacteriophage, whereby permeability decreased with the use of probiotics and the above-mentioned active agents. In general, the decrease in productivity was significant in all groups. However, the effect of spore-based probiotics was quite pronounced against the background of eimeria polyresistance. In the situation where anticoccidial drugs are less effective, the use of a spore-based probiotic can have a noticeable protective effect. The effect of all anticoccidial drugs under study on the concentration of oocysts and the state of the mucosa was insignificant, which indicated polyresistance of different types of eimeria isolated from biological material to these drugs. The analysis of the intestinal mucosa integrity, based on the study of mucosa permeability to bacteriophages and a Johnson and Reid scoring procedure showed that a spore probiotic based on B. subtilis and anticoccidial drugs containing robenidine and salinomycin had the best protective effect against eimeriosis caused by field isolates of eimeria. When treating chickens suffering from eimeriosis caused by polyresistant forms of E. acervulina and E. tenella, it is advisable to use probiotics alongside with drugs based on robenidine and salinomycin.
