Influence of Strain and Feed Restriction on Haematological Parameters of Commercial Cocks | Asian Jo

Feed restriction strategy has been introduced as a way of restricting bird access to feeds during the day without sacrificing the quality of poultry products due to the high cost of feed ingredients and its negative impact on production cost in the livestock subsector. The aim of this analysis was to see how two commercial cock strains responded to different feed restriction regimens. To analyse and compare their blood parameters, 180 day-old cockerels of two strains with Black and White plumage (90 chicks each) were obtained. The birds were divided into four treatments with three replicates for each strain at the 6th week of life.T1: monitor (ad libitum), T2: feed restricted (6th -7th week), T3: feed restricted (8th -9th week), and T4: feed restricted (8th -9th week) are the therapies (10th -11th week). At the end of the 16th week, one bird from each duplicate was selected at random for blood collection into labelled sample bottles treated with anti-coagulant and transported to the lab for examination. The results showed that, with the exception of Basophil, there was no important (P>.05) impact of strain on any of the parameters measured.Furthermore, except for white blood cell, lymphocyte, and heterocyte, there was no important (P>.05) impact of feed restriction on packed cell length, haemoglobin, red blood cell, platelets, monocyte, eosinophil, and basophil. It's worth remembering, however, that the obtained mean values for all parameters were comparable and within the ranges previously stated for chickens.
