Environmental factors such as stocking density can cause stress and negatively affect the physiological status and meat quality of broiler chickens. In the current study, we evaluated the effects of increased rearing density on the growth performance, stress, fear levels, meat quality and liver histopathology of broilers as well as suggesting a use of different supplementations that may be helpful to reverse such adverse effects. Three hundred sixty one day-old cobb broilers (44.0 ± 5.24 g live-weights) were randomly distributed to 24 replicate pens to create two different stocking densities (D10 and D15 bird/m2) with the different supplementation treatments: 1) 10 birds/m2/pen (without any treatment, control, "CD10"), 2) 10 birds/m2/pen (moringa aqueous extract treatment "MAED10"), 3) 10 birds/m2/pen (synbiotic "SynD10"), 4)15 birds/m2/pen (without any treatment control SD15 "CD15"), 5) 15 birds/m2/pen (moringa aqueous extract treatment "MAED15"), 6) 15 birds/m2/pen (synbiotic "SynD15").  Results of the current study revealed that there was a significant increase in the overall experimental period body weight gain (P<0.01) with increasing density without affecting feed intake, body weight and feed conversion ratio. High stocking density resulted in significantly increased corticosterone (P>0.001), altered brain monoamines, deteriorated some carcass quality parameters and declined liver health. Additionally, it was concluded that moringa aqueous extract (MAE) and synbiotic (Syn) supplementation have a significant effect in reversing the catastrophic effect of high stocking density (SD) with minimal effect at the lower density groups.

The prevalence of Babesia infection was studied in newly purchased Tellicherry goats from Thalasserry, Kerala State to a private goat farm at Chennai. A total number of 168 goats were examined for the presence of Babesia. The study revealed that 58 (34.5%) goats were infected with Babesia ovis. The prevalence of Babesia infection between males and females and different age groups of goats was non-significant. Infected goats showed varying clinical signs of inappetence, depression, increased respiratory rate, weakness, coughing, nasal discharge, ocular discharge, diarrhea,&nbsp;&nbsp; body temperature ranging 39.5- 41.2oC and abortion. Blood parameters revealed decrease in total red blood cells (RBC) count, haemoglobin concentration (Hb), Volume of packed red cells (VPRC), platelets counts and increase in lymphocyte and neutrophil count.
