This epidemiological study was carried out by distribution of questionnaire among veterinary practitioners managing some dairy farms in Eastern Algeria. The frequency of endometritis according to other pathological entities, the epidemiological analysis according to the race, the season and the rank of the calving, the complications, the therapeutic protocols applied by the veterinarians as well as the prophylactic measures were the object of our study. The results of the survey showed that the per centage of endometritis in relation to other health problems is between 10 and 15 per cent. According to the degree of intensity of the symptoms, it was noted that the first degree endometritis represented 29.54 per cent of the cases surveyed while the second and the third degree endometritis represented 27.87 per cent and 20.45 per cent respectively. Most of the clinical cases were treated with prostaglandin F2α, with a frequency of 72.72 per cent, while 22.72 per cent of the cases did not undergo any hormonal treatment. The systematization of the epidemiological study of endometritis in cows should guide the therapeutic approach to better control infertility in intensive dairy farms.
Background: This study was performed to evaluate the performance of low soybean meal diets in broiler chicks. Methods: A total of 330 broiler chicks were divided into three groups. Each group was treated with one type of diet (group 1=control [soybean], group 2=crushed peas, and group 3=faba bean). The proportion of crude protein (CP) for the control group was 20.45% as a starter and 19.75% to 17.66% as a grower and finisher. The CP values for group 2 were 17.45% as a starter and 16.95% to 15.46% as a grower and finisher. While chicks of group 3 received 17.75% CP as a starter and 17.23% to 15.68% CP as grower and finisher. Data obtained were expressed as mean±SEM. The results obtained were analyzed using the ANOVA Test, by Minitab 2015 statistical analysis software. P-value < 0.05 was considered as significant. Results: Significantly (p<0.05) higher weight gain was obtained in the faba bean group (2744.72 g ±217) than control (2430.50 g ±593.8). No significant difference was noticed in the consumption of different diets. The carcass yield of control (70.10%) and faba beans (70.32%) groups were comparable. Concerning the biochemical parameters, we found that the partial change of soybean did not affect the biochemical profile, except for the significant variation of blood sugar, cholesterol, and triglycerides between the control and group 2 (p<0.05). Conclusion: Faba beans as a locally available source of protein could be a potential alternative to substitute soybean meal in the broiler diet.
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.
