Objective: This study was conducted to evaluate the pathological effects of experimental trypanosomosis on the semen collection reaction time and spermatozoa morphology of Yankasa rams. Materials and Methods: Twelve apparently healthy Yankasa rams aging 24-30 months and weighing 22-25 Kg were randomly selected and were distributed into four (4) groups. Groups I and II were challenged with exper...

The effects of trypanosomosis on the scrotal circumferences and semen characteristics of Yankasa rams were studied for ninety eight days (14 weeks). Sixteen Yankasa rams aged between 24 to 30 months and weighed between 22 to 25 kg were acclimatized for a period of two months in a clean flyproof house and were adequately fed and given water ad libitum. Of the sixteen rams, twelve that were clini...

AIM The study was conducted to evaluate the pathological effects of trypanosomosis on the testes, gonadal, and epididymal sperm reserves of Yankasa rams for 98 days. MATERIALS AND METHODS A total of 16 Yankasa rams, aged between 24 and 30 months and weighed between 22 and 25 kg, were acclimatized for a period of 2-months in a clean fly proof house and were adequately fed and given water ad-li...

The effects of feeding different levels of dried layer litter as a protein source on live weight, testicular weight, gonadal and epididymal sperm reserves of Yankasa rams was investigated in a 98day study. Twenty healthy Yankasa rams with clinically normal genitalia were divided randomly into 4 groups (A, B, C and D) of 5 rams each. Diets containing 12.11% CP, 14.96% CP and 17.94% CP were formu...

Effect of dietary treatment levels on body linear measurements of growing Yankasa rams (Ovis aries) fed sorghum (Sorghum bicolor)Moench stover supplemented with graded levels of dried poultry dropping based diets was assessed using thirty growing Yankasa rams (Ovis aries) consisting of five treatments (T1-T5). Each treatment consisted of three replicates with two animals per replicate. T1: were...

Dexamethasone is widely used in both veterinary and human medical practices. However, it seems to cause some deleterious effects on pregnancy probably by causing changes in the reproductive hormone levels and their corresponding receptor concentrations. This study investigated the effects of dexamethasone on these parameters. Twenty healthy adult Yankasa sheep comprising 18 ewes and 2 rams were...

A feeding trial was conducted to assess the effect of inclusion of ensiled sugarcane waste (ESCW) with poultry litter on performance of Yankasa rams in a completely randomized design (CRD) for twelve weeks (84 days). Sugarcane waste was mixed with poultry litter in 3:1 and ensiled for 21 days. The ESCW was used as partial replacement in complete diet. Sixteen Yankasa rams (mean body weigh 28.94...
