Abstract

This study was designed to determine the effect of tamarind leaves aqueous extract on semen quality, testicular morphometry and immune traits of Noiler cocks in a hot dry environment. Twenty-four (24) Noiler cocks of thirty-two (32) weeks of age were used for the experiment. The birds were reared on deep litter and were fed ad libitum with a commercial feed (14% CP) throughout the twelve weeks’ experimental period. The tamarind leaves aqueous extract (TLE), were obtained by boiling a known quantity of the leaves with tap water for ten minutes and allowed to cool and then filtered. The filtrate (extract) was given to the cocks as drinking water throughout the experimental period. Fresh extracts were prepared every day. The cocks were divided into four treatment groups, each replicated three times in a Completely Randomized Design and offered the tamarind leaves extract as follows; T1 = Control (No tamarind leaves extract), T2 = 5g tamarind leaves in 1litre of water, T3 = 10g tamarind leaves in 1litre of water, T4 = 15g tamarind leaves in 1litre of water. Data was collected on semen volume, colour, motility, concentration, testicular morphometry.  Semen volume (0.43 ml) was highest (p<0.05) in cocks given 10g TLE/l. Aqueous tamarind leaves extract had no effect on pH, mass motility and percentage abnormal sperm cells. Individual motility was low (p<0.05) at 15gTLE/l. Sperm concentration and percentage dead sperm were highest (p<0.05) in the group given 10g/l TLE. Cocks given 10g/l TLE had heavier (p<0.05) left and paired testicular weights. There was significant influence of TLE on eosinophils, total protein, albumin and globulin, while means for white blood cells, neutrophils and lymphocytes were similar for all treatments. It was concluded that 10g/L aqueous tamarind leaves extract (TLE) positively influenced semen quality, testicular morphometry and immune response of Noiler cocks in a hot dry environment.
