The purpose of this research was to know the relationship between age with calving inteval (CI), days open (DO), and service per conception (S/C) in Friesian Holstein dairy cattle (FH). The research was started on Desember 2017 to January 2018 in PT. Greenfields Indonesia partnerships, KecamatanWagir Kabupaten Malang. The materials of the search used were 100 heads of dairy cattle which had at least two times of parturition. The method used in this research was a survey and data collection. The data were obtained from the records of reproduction. Data analysis was multiple linear regression using SPSS software 21.0 version. The results showed that the values of CI (434,9±58,9 days, 449,4±66,2 days, and 431,8±59,2 days), DO (218,9±58,7 days, 218,9±58,7 days, dan 217,6±54,1 days), dan S/C (3,2±1,8 times, 4,3±1,9 times, 2,6±1,1 times) for the ages of 4, 5, 6. The relationship between age with CI and DO were not significant (P>0,05), but the relationship between age with S/C was significant (P<0,05). The value of S/C increased on dairy cattle at age of 4 to 5 years and started to decreased at the age of 6 years.
High temperatures lead to oxidative stress which can decrease the quality of spermatozoa. Watermelon’s rind have an ability for antioxidants effect that can reduce sperm’s damages that results by role explanation of free radicals. This study aimed to determine the effect of extract of watermelon’s rind on the motility and viability of sperm on male rat exposed to heat. This experiments use rat as animals experiment with five treatments and four repetitions. Five treatments are: P0: without exposured to 40˚C of temperature and without treatment by extract watermelon’s rind, P1: was exposured to 40˚C of temperature and without treatment by extract watermelon’s rind, P2: was exposured to 40˚C of temperature and treatments by extract watermelon’s rind dosage 20 mg/rat/day, P3: was exposured to 40˚C of temperature and treatments by extract watermelon’s rind dosage 40 mg/rat/day, and P4: was exposured to 40˚C of temperature and treatments by extract watermelon’s rind dosage 80 mg/rat/day. The treatment was done for 52 days. The results, P4 have the best effect that can be increase the motility and viability of rat’s sperm (Rattus norvegicus) exposed to heat.
Background: Making silage added with additives can improve the quality of silage nutrition and speed up the fermentation process. Molasses are widely used by farmers as additives for making silage. The use of molasses can be replaced with Fermented Mother Liquor (FML) in making silage. Purpose: to determine the effect of molasses addition on physical and chemical quality of corn plant silage given Fermented Mother Liquor (FML). Method: Observative data collection by making direct observations on making silage with two treatments consist of P0 (Corn Plant + 2% Fermented Mother Liquor (FML)) and P1 (Corn Plant + 2% Fermented Mother Liquor (FML) + 2% Molasses). The silage storage time was one week and on the seventh day observations were made on the physical and chemical quality of silage in each treatment. Result: The corn plant silage given fermented mother liquor (FML) without the addition of molasses produced better physical and chemical quality compared to corn plant silage given Fermented Mother Liquor (FML) with the addition of molasses. Conclusion: the corn plant silage given Fermented Mother Liquor (FML) only had better physical and chemical quality
The aim of this research was to know whether pineapple peel juice can be used as an ovicidal of in vitro A galli. This study used eggs of A. galli worms obtained by collecting adult A. galli worms from the small intestines of fresh local chickens purchased from traditional markets in Surabaya. The research design used was a completely randomized design (CRD) with four treatments , the concentration of pineapple peel juice was 0% (Control), 5%, 10%, and 20%. Each treatment consisted of six replications, with observations on days 5, 10, 15 and 20. Developed eggs were identified with the presence of larvae within egg and the movement of larvae. The data obtained will be analyzed with the ANOVA Statistical Test with the SPSS device and then followed by the Duncan test. The results of statistical analysis showed that pineapple peel juice had a significant effect on the development of A. galli worm eggs In Vitro. The number of damaged A.galli eggs increased as they were given higher pineapple juice concentration. This proves that pineapple peel juice has higher anthelmintic effect with increasing concentration given. Pineapple peel juice 20% is the best juice concentration.
This research was conducted to observe the effect of polypropylene plastic residue on heated palm oil against the histopathological changes on rat’s kidney. There were 18 male rats (Rattus norvegicus) that used as the examination animal and were divided into three groups and were given the mixture of heated palm oil and polypropylene plastic per oral with intubation needle. The treatment was done for five weeks. The treatment for P0 group was 84 g of palm oil, for P1 was 84 g of palm oil with 2.3 g of plastic, and for the P2 was 84 g of palm oil with 6.8 g of plastic. The histopathological changes of the kidney were observed using microscope with 400x magnification and the data was analysed using Kruskal-Wallis and continued with Mann Whitney U test. The result showed that there were significant differences between three groups of treatment (P<0.05). There were effects of polypropylene plastic residue on heated palm oil against the histopathological changes of kidney in this research such as cast, epithelial sloughing and necrosis in the mild scale.
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.
