Behavioural and health status assessment of cattle in a semi-intensive system
摘要
The productivity of ruminants is largely hinged on nutrition and management systems. Hence, a 2-month study was conducted to assess the behaviour, welfare, and health status of White Fulani (WF) and Sokoto Gudali (SG) cattle breeds raised under a semi-intensive farming system. A total of 60 cattle were evaluated using Qualitative Behavioral Assessment (QBA) parameters such as activeness, friendliness, and agitation; assessed skin condition (e.g., cleanliness, hair loss, ocular and nasal discharge, diarrhea, and lameness). Data/observations were taken twice weekly. 10 mL of blood samples were collected from all the animals for haematological and serum biochemical studies. All data collected were subjected to appropriate statistical analyses. Results from QBA revealed marked differences in activity levels and sociability. WF cattle showed greater calmness (90.91%) and more frequent cud-chewing (92.31%), while SG cattle displayed greater sociability (68.75%). Skin condition assessment revealed a higher proportion of WF cattle (96.00%) has cleaner skin when compared to SG cattle (83.00%). Neither breed had diarrhea nor lameness, while minor ocular and nasal discharges were observed. Haematological and serum analyses revealed no significant (P > 0.05) differences, although WF cattle had higher values across most parameters except the mean corpuscular haemoglobin concentration (33.26 g/dL), granulocyte (42.17%), and monocyte (2.50%) count. SG cattle had higher total protein (81.63 g/L), albumin (30.53 g/L), aspartate aminotransferase (78.05 IU/L), alanine transaminase (67.10 IU/L), and cholesterol (3.81 mmol/L) concentrations, while WF cattle had higher globulin (52.22 g/L) and glucose (46.00 mg/dl) concentrations. Thus, findings highlight breed-specific behavioral differences in cattle raised under semi-intensive systems, while haematological and serum indices were indifferent.
