The laying hens received treatments for six weeks (42 d). The encapsulated probiotic was used to improve probiotic durability from intestinal damage. The health status consisted of blood and immunity profiles, including leukocytes, erythrocytes, haemoglobin, and haematocrit, CD8+, CD4+, malondialdehyde, and B cells. The water quality was improved by the use of magnetic technology. Magnetic technology effectively decreased the CD8+ , CD4+ , malondialdehyde, and B cells in the blood of laying hens compared to treatments without magnetic technology.

The levels of neutral detergent insoluble nitrogen and acid detergent insoluble nitrogen exceeded the upper limit of 311 g/kg of N. Of the studied silages, an NDF content of 734 g/kg was obtained in Maxisilo, which was higher than the other silages (average: 547 g/kg). Silage production can be achieved with the four materials; however, the Maxisilo sorghum provides silages of lower quality, with a DM content of less than 30%.

In the first year of the study, a total of 45 animals were used to determine the milk yield characteristics of the three genotypes. In the second year, a total of 56 does and 62 goat kids were used to determine the characteristics of the animals. The ICAR AT method was used to calculate the lactation milk yield of the goats. The average lactation lengths, the average lactation milk yields, and the daily average milk yields of Alpine × Hair-crossbred, Saanen × Hair-crossbred, and Hair goats were 242, 232, and 229 days; 182, 201, and 164 kg; and 0.754, 0.873, and 0.716 kg, respectively. The effect of genotype on lactation milk yield and daily average milk yield was statistically significant. Live weights of the kids were recorded at monthly intervals and live weights of the kids for days 30, 60, 90, and 120 were calculated by linear interpolation. The effect of genotype on the 90- and 120-day weights were similar. Measurements of udder characteristics were determined twice, at the beginning (30 d) and at the end (180 d) of the lactation period. It was determined that crossbreeding had no effect on udder characteristics except the distance between teats and udder depth. The main result of this study is that crossbreeding substantially increased milk yield in goats, even at the F1 level, under extensive conditions.
