Testicular Parameters and Sperm Morphology of Chinchilla Rabbit Fed With Different Planes of Soymeal

Abstract

The testicular parameters and sperm morphology were studied in twenty healthy Chinchilla breed bucks of rabbits fed with different planes of soybean meal. Their ages were between 6 to 10 months with their weights ranging from 1.4 to 1.9kg.The same quality of feeds was fed to each group throughout the study and at the rate of 0.5kg/head/day. The feeds contained graded percentage of soybean meal and growers mash.Semen used in this study was from the caudal epididymides while morphological aberrations were determined from a total count of 400 spermatozoa in smears obtained with Wells and Awa stain.Results of the spermiogram showed that the colour and consistency of the semen appreciated as the percentage of soybean meal increased. Group D with 90% soybean meal was significantly higher (P<0.05) over and above the values of other groups. Group D had a significant increase (P<0.05) over and above values of other groups in terms of percentage live spermatozoa. Semen concentration increased from 1.20 ± 1.56 x10 6 /ml in group B with 30% soymeal to 2.00±2.67 x10 6 /ml in group D with 90% soymeal. Testicular parameters also showed that there was more weights increase as the percentage of soymeal in the feed increased.It is therefore concluded and recommended that soymeal can be part of normal diet of Chinchilla Rabbit without any adverse effect on the reproductive potential of the male rabbit.

Effect of human menopausal gonadotropin on testicular morphometry, gonadal and extragonadal sperm reserves of rabbit bucks

“…However, other measured testicular parameters were consistent with the report of Oyeyemi and Okediran (2007) but higher than the mean values reported by Oguike and Archibong (2011). These differences in testicular parameters could be due to breed differences, or variation in age of bucks (Oyeyemi and Okediran, 2007).…”

“…The mean testis weight recorded in this study was higher than 3.1 g reported by Franca et al (2002) but lower than 6.7 g reported by Herbert et al, (2005). However, other measured testicular parameters were consistent with the report of Oyeyemi and Okediran (2007) but higher than the mean values reported by Oguike and Archibong (2011). These differences in testicular parameters could be due to breed differences, or variation in age of bucks (Oyeyemi and Okediran, 2007).…”

Morphological Characteristics and Haematological Studies in Wistar Rats Subjected to Prolonged Treatment of Chloramphenicol

“…It is now observed from this study that prolonged treatment of chloramphenicol will cause infertility when used at 25mg/kgbw for 20 to 25 days. This observation is similar to reports of Oyeyemi & Okediran (2007), Hughes & Varley (1980). The decrease noticed/observed as per the days of treatment in semen concentration indicated that prolonged treatment of chloramphenicol has adverse effect on fertility potential of the male animal.…”

Sperm quality and testicular morphometry of rabbits fed dietary levels of water spinach (Ipomoea aquatica) leaf meal

“…The values were within the range of 6.00 to 16.00% reported by Ajayi (2009). The percentage of abnormal sperm cells in this study were below the upper limit of 20% recommended as the minimum for good reproductive potential and fertility in either normal mating or in artificial insemination (Oyeyemi and Okediran, 2007). The result of the visceral organ weights of male rabbits fed water spinach is presented in Table 4.…”
