The objective of this study was to determine the effect of live weight (LW) on libido, sperm quality, testosterone, luteinizing hormone (LH) in Ongole grade (OG) bull. This study used 32 heads of OG bull with a completely randomized design that were divided to four different LW groups, i.e. group I was 170 to <210kg, group II was 210 to <250kg, group III was 250 to <290kg and group IV was 290 to 330kg. Parameters: observed were libido, testosterone hormone, LH, and semen quality. Data were analyzed by ANOVA. Libido of OG bull in group II and III higher than those in group IV. The testosterone hormone and LH showed that group II, III and IV were better than group I. The highest LH was in group IV, but low levels of testosterone were observed in these respective groups. Live sperm was the lowest in group I (21.25±13,20%) than II (66.00±11.17%), III (59.80±22.20%) and IV (75,67±9.46%). It can be concluded that the libido, sperm quality, testosterone, LH of OG bull in group II, III and IV were better than those in the group I, therefore standard LW of OG bulls had at least 250 kg.
Background and Aim: Among several factors, the sperm quality of poultry is affected by the rooster's body size and the availability of antioxidants like vitamin E. This study aimed to determine the effect of dietary vitamin E supplementation on rooster sperm quality through a meta-analysis. Materials and Methods: After verification and evaluation, a total of 19 articles were included in this study. Data, including dietary vitamin E, semen volume, concentration, total sperm cells, pH, motility, viability, percentage of dead and abnormal sperm, vitamin E sperm content, malondialdehyde (MDA) content, and testosterone levels, were tabulated in a database; these were subsequently analyzed using mixed modeling with vitamin E dose as a fixed effect and study identity as a random effect. Results: Dietary supplementation level of vitamin E significantly (p<0.001) affected sperm concentration, significantly affected motility (p<0.001), significantly affected sperm vitamin E (p<0.001), significantly affected viability (p<0.001), and significantly affected chicken sperm fertility (p=0.001). Vitamin E administration also significantly reduced the number of sperm cell deaths (p<0.001); however, increased dietary levels of vitamin E did not affect semen volume (p=0.853), pH (p=0.951), MDA (p=0.542), the percentage of abnormal sperm cells (p=0.343), nor testosterone levels (p=0.063). Conclusion: Dietary vitamin E supplementation is recommended for male chickens since it generally enhances the quality of their sperm.
Hormonal fluctuations in livestock will affect vaginal cytology good overview on the condition of estrous until pregnancy. The purpose of this study was to determine the physiological condition of Ongole crossbred (PO) cow during estrous and determine pregnancy by the description of vaginal epithelial cells, progesterone, and estrogen hormone profiles. The materials were used 35 cows with physiological status (estrous, 5th pregnancy period, 16th pregnancy period, 22nd pregnancy period, and 60th pregnancy period). Samples of Vaginal smear were stained with Giemsa, then it was observed using a microscope, with 40 times magnification. The progesterone and estrogen were analyzed by the ELISA method. The parameters measured were the percentage of vaginal epithelial cells, such as (parabasal, intermediate, and superficial) started estrous phase until the time of pregnancy in cows (5, 16, 22, and 60 days), hormone concentration, as well as the presence or absence of leukocytes. The result showed the Ongole crossbred cow estrous phase percentage of superficial cells 56.27%±6.49 higher than 26.23%±7.98 intermediate cells, followed by parabasal cells 17.50%±4.74. While in Ongole crossbred that were 5th pregnancy period until the 60th predominantly intermediate cell 80.43%±1.31, then the superficial cells 18.09%±1.30 and 1.48%±0.04 parabasal cells. Progesterone concentration was 63.74±1.07 ng.mL-1 in estrus cows, and steadily increased 93.71±0.94 ng.mL-1 to 149.5±0.71 ng.mL-1 in pregnant cows (5-60 days). The concentration of high estrogen levels were 122.38 ± 0.63 ng.mL-1 in the estrous phase, then decreased 81.54±0.44 ng.mL-1 in the pregnancy phase. In conclusion, the concentration of hormone showed a diagnosis of pregnancy, which done by looking at changes in vaginal epithelial cells at the Ongole crossbred cow, and the cow estrous phase showed greater superficial cells compared by pregnant cows (5-60 days).
This study aims to provide information on cases of reproductive disorders in beef cattle which maintenance systems group in the Beef Cattle Research Station of the year 2013-2016. The material used was 130 Bali and Madura cattle. The parameters observed dystocia, abortion, retained scundinae, uterine prolapse. Data were analyzed descriptively. The results showed reproductive disorders in Bali cows 2 years old dystocia highest cases (3.08%) and abortion (0.77%), at the age of 5 years in case of the highest retention (4.62%), then in the Madura cows at age 3 cases of uterine prolapse and retained scundinae each (1.54%), the age of 4 years in case of the highest retention scundinae (2.31%), aged 5 years scundinae retained the highest cases (3.86%). The incidence of reproductive disorders in Bali cows body weight poor level (≤250 kg) cases that present the highest retention scundinae (3.08%), body weights moderate level (251-300 kg), dystocia (0.77%) and retention scundinae (0.77%), the body weight fat level (≥301 kg) retained scundinae cases (0.77%); Madura cows body weight poor level scundinae retained the highest cases (3.08%), the weight being retained scundinae cases (1.54%) and body weighted fat level retention scundinae cases (0.77%). Reproductive disorders in Bali cows low birth weight (≤15 kg) retained the highest case scundinae (4.62%), moderate birth weight (16-20 kg) and height dystocia cases arising each (1.54%); for Madura cows at a lower weight retention scundinae highest cases (3.08%), medium and high weight retention scundinae each (2.31%). The conclusion is that the highest incidence rates in reproductive disorders based on age, weight of the cows birth and birth weight in Bali and Madura cows is retained scundinae case. Therefore, prevention can be done by paying attention to the feed, houses, sanitation, health and cows because reproduction capabilities of each cows is different.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
