Macroscopic & microscopic survey of native goat kids livers and kidneys feed with seaweeds of Bushehr province

To evaluate the effect of feeding seaweed Sargassum Angustifolium on the liver and kidneys, the 24 heads of native goats kid Bushehr province, with an average live weight of 15/64 ± 3/2 and the average age of 5-6 months in a completely randomized experimental design with 3 levels of edible algae in the diet (0, 10 and 20%) and 8 replicates (animals) per treatment, was 75 days. Experimental groups of 10 and 20% algae (n = 24) for 75 days with Sargassum seaweed off the coast of Bushehr and control group (zero percent algae) in this period were fed with normal diet. To investigate the possibility of macroscopic and microscopic lesions in the liver and kidney, respectively, in the four experiments at day 15, day 30 of the experiment, day 45 day trial and 75 days of the end of the experiment at any stage of the vertices of two kids as well randomly selected from each treatment were slaughtered. After killing them all, kidney and liver was transferred to a laboratory animal with complete specifications. Macroscopic results of all kidney and liver treatments, showing no signs of liver damage and kidney involvement is revealed. Microscopic examination of congestion and in some cases only limited and small foci of necrosis in experimental treatments (fed with Sargassum algae than 10 and 20%) and control in liver and kidney was observed. In order to complete this study, Examined Interactions and simple during the finishing period And the percentage of algae on the carcass of 55 fattening lambsAnd the average percentage of the effect of algae on the characteristics of feedlot fattening lambs. Results showed no significant differences between the effects of fattening period and the percentage of algae is found on goat carcass (P 0/05). But during the finishing period had a significant effect on the goat carcass (P 0/05). The percentage of algae also has a significant effect on animal carcass (P 0/05). So that the treatment of 20 percent compared to 10 percent better carcass algae and algae control is. And between 10 and 20 percent algae control treatment there was a significant difference (P 0/05). The effects of different percentages of algae out of the features of fattening lambs fattened results are significant differences between the final weight (kg) and daily weight gain (g) in different treatments showed (P 0/05) so that Algae 20% treatment, final weight and daily weight gain better than 10% of the treated and control algae were And between 10 and 20 percent algae treatments were significantly different from the control (P 0/05). But the initial weight, feed intake and FCR kids were not influenced by different percentages of algae and no significant difference was observed between them (P0/05). As was seen in this study, the use of seaweed Sargassum Angustifolium doses used (10 and 20%), Due to the presence of heavy elements in it, Has not harmful effects on the kidneys and liver tissues of kid goats . But due to the positive effects of the algae on carcass and higher weight than animals treated with 20% in algae, it can be concluded that the alga Sargassum up to 20 percent of the diet is good kids. And the food can be in drought conditions, high prices and scarcity of forage in the diet of animals can be used as a very convenient option. Keywords: seaweed, Sargassum, liver, kidney, Bushehr
