Unconventional diet, Haematological parameters, Blood, PigAbstract
The study aimed to evaluate the effect of chicken and fish viscera used as feed supplement in pigs on fattening. Ninety crossbreed (Local x Large White) weaned pigs of 12 weeks old, weighing on average 9.5kg were divided into five groups of eighteen. Each group was assigned to one of the five diets contained 0% (control), 0, 1.5, 3.5 and 5% of chicken viscera and respectively 0% (control), 5, 3.5, 1.5 and 0% of fish viscera for 90 days. Haematological parameters like Packed cell volume (PCV), Haemoglobin (Hb), Red blood cell (RBC), White blood cell (WBC), Mean corpuscular haemoglobin (MCH), Mean corpuscular haemoglobin concentration (MCHC) and Mean corpuscular volume (MCV) were studied. After 90 days of rearing, four pigs from each group were slaughtered for carcass trait analysis. Offal and carcass weights and carcass length were recorded. Results showed that the haematological parameters weren’t different (P>0.05) among treatments. The RBC and WBC of the control group A0 was higher than those of dietary treatments and the standard value. In addition some value of platelets were lower than the minimum value adapted from Coronado 2014.
