ABSTRACT

The experiment was conducted to determine semen quality, fertility, egg hatchability and some biochemical parameters in Nigerian local turkey toms fed diets containing Moringa oleifera (MO), Gongronema latifolium (GL) leaf meals and their combinations. A total of 72 Nigerian local turkeys comprising of 54 males and 18 females were used for the study. The males were randomly divided into 9 treatment groups, each treatment was replicated 3 times with 2 toms per replicate. The treatment diets were given only to the toms, starting from three month of age through the experimental period. The experimental animals were fed and given water properly, twice a day without restriction. All the management practices were carried out to the best of ability. The males in all the treatment groups were weighed weekly to determine their daily and weekly body weight gain. At 26 weeks of age, toms were trained for semen collection, and 32 weeks of age, semen was collected using abdominal massages. Samples were analyzed for colour, volume, progressive motility, sperm concentration, viability and sperm morphology. Fresh semen sample were also collected per treatment in vials’ stored in ice block and analyzed for fructose, Na and K.  A total of 18 hens were randomly shared 2 per treatment corresponding to the 9 treatments. Pooled Semen from each treatment was used to inseminate the hens twice a week at the beginning of egg lay and once a week subsequently. A total of 225 eggs were collected and incubated in weekly batches, analyzed for fertility and hatchability. The result revealed that M. oleifera and G. latifolium leaf meals had significant (P<0.05) effects on the semen quality parameters measured. M. oleifera fed tom at 3kg yielded the best result: ejaculate volume 0.58ml, motility= 92.93%, Conc.= 4.82(x10/ml 9), live sperm= 94.13%, normal sperm 91.38% and corresponding lower values for percentage dead and abnormal sperm. While, G. latifolium treated toms had a lower value for their semen quality parameters when compared with the control group. Interaction effects of M. oleifera and G. latifolium leaf meals were significantly (P<0.05) different. Compared with control semen quality traits were higher at 3kgMO+1.5kgGL inclusion, lower at 1.5kgMO + 1.5kgGL, and significantly reduced semen quality of toms fed 1.5kgMO+ 3kgGL diets.  Similarly, the percent fertile eggs, and percent hatched eggs were greatly improved at 3kgMO diets with corresponding decrease in percent infertile eggs and dead in shell embryos than the control. However, toms fed diet at 1.5kgGL and 3kgGL had their values for these parameters being severely reduced. Hatchability values increased to 88.39%  and 83.33% at 3kg MO+1.5kgGL and 3kg MO+3kgGL respectively with a decrease in percent dead- in- shell embryos to 16.99% and 19.12% respectively. Seminal fructose concentration (mg/100ml) was significantly (P<0.05) increased (5.86+2.76) at 3kgGL when compared with the control, but M. oleifera had a negligible increase in fructose concentration. However, M. oleifera fed toms (3kg) had a significant(P<0.05) increase in concentration of Na and K (0.39 and  0.35) respectively. These result suggest that improved fertility, eggs hatchability and reduction in percent embryo mortality can be achieved using M. oleifera at 3kg/100kg diet  and combination of M. oleifera+G. latifolium at rate of 3kgMO+1.5kgGL, but treatment with G.latifolium at the rate of 1.5kg, 3kg and combination at rate of 1.5kgMO +3kgGL caused reduced fertility in local Nigerian turkey.

 

CHAPTER ONE

INTRODUCTION

  • Background of the study

In Nigeria, poultry industry is once again experiencing growth due to the current regime’s effort at encouraging investments in the industry through several economic and agricultural policies and reforms including removal of import duties on agricultural products (Fasina et al., 2007). Notwithstanding, the current trend in growth within the industry it is still experiencing challenges as some species of poultry are left out. For instance, turkey production has not been as successful as chicken production in Nigeria. Its production is largely at the small holder level. This has been attributed to high cost of feed, inconsistencies in feeding program as well as lack of information on its nutritional requirements (Ojewola et al., 2002). Also, reproductive problems experienced under natural mating conditions, low fertility and poor hatchability as a result of poor quality semen due to oxidative stress amongst other factors (Bucak et al., 2010) militate against turkey production in Nigeria.  This situation is also evident from the FAO report (FAOStat, 2011), which shows that the population of  local turkeys in Nigeria is only about 1.05 million, being the smallest when compared with other poultry species. It is important to come to terms with the fact that advancement in the industry depends on the use of birds with high reproductive rate, adoption of better mating methods, use of high quality semen in insemination as well as good nutrition.
