This study aimed to determine if the homeopathic formulation based on Natrum muriaticum, Matricaria, Chamomilla, and Ignatia amara was effective for stress control in dogs in order to prevent and/or reduce the frequency of unwanted behaviors. Ten male beagle dogs were divided into two groups, with five animals per group. The control group was animals receiving 0.5 mL/day of placebo via spray in the feed for 30 consecutive days as a preventive. The treated group received 0.5 mL/day of tested drug spray in the feed for 30 consecutive days as a preventive. Behavioral tests were performed at two time points, before and after receiving the tested drug. We performed the following behavioral tests: a) persons known and unknown in the internal and external environment; b) interaction with toys; c) interaction with an unknown dog, d) test with a leash; and e) firecracker test. There was more engagement in digging and scaling the fence in the control group than in the treatment group (P < 0.05). The animals that received homeopathic medicine sat 2.54 times longer than the control (P = 0.0269). Dogs that received homeopathic showed 4.49 times more interest in general at D30 than at D1 (P = 0.0214). Animals in the treated group showed an 83% less chance of urinating than the control group in the tests involving displacements. We conclude that the preventive addition of homeopathic medicine containing Natrum muriaticum, Chamomilla, and Ignatia amara reduced undesirable behaviors related to anxiety and increased the incidence of interest behavior.

The aim of this study was to determine whether a combination of seaweed flour (Lithothamnium calcareum) and a homeopathic added to broiler feed has a hepatoprotective effect capable of minimizing the negative impacts of aflatoxin B1 toxicosis. We used birds one day divided into four groups with six repetitions per group and 20 birds per repetition in a completely randomized design. The combination of seaweed flour + homeopathic product was identified as the test product (TP). The groups were identified as PC: intake of 300 µg/kg of AFB1 (positive control); PC+TP: intake of 300 µg/kg of AFB1 + 2 g/kg of TP; NC: birds that received control feed; and TP: supplemented with 2 g/kg TP. The birds in the PC+TP, NC and TP groups had the higher body weights on days 35 and 42 days than in the PC group. This same effect was also observed for daily weight gain and feed conversion for 1–42 days. A higher villus: crypt relationship was observed in PC + TP, NC and TP compared to PC. The seaweed flour combined with the TP minimizes the negative effects of AFB1 on the liver health of broilers and consequently avoids losses in zootechnical performance.
