Biochemical alteration of some serum constituents in laying hens supplemented by high fat rations

For performing this study, 40 pullets were divided classified into four equal group, one given basal diet only, 2[nd] group kept on basal diet plus beef tallow, 3[rd] group given basal diet plus linseed oil and the last group was supplemented with basal diet and olive oil. Blood samples were collected 4 and 8 weeks post-treatment and the obtained results revealed that the total serum lipids, cholesterol and triacylglycerol, were significantly increased at eight weeks in beef tallow and linseed oil treated group while, they were greatly decreased in olive oil treated group. On the other hand, the serum proteins values were significantly decreased in all treated birds after 8 weeks. The present work provides evidence that all types of lipids used in this work significantly decreased the concentration of serum calcium, phosphorus, magnesium, iron while, most of them increased the serum copper concentration

electrophoretic pattern of serum proteins in chickens vaccinated with newcastle [different strains and gumboro vaccines

The present work was planned to study the effect of vaccination with different strains of Newcastle disease virus vaccine [NDVV] as well as vaccination with Gumboro vaccine on the electrophoretic pattern of serum proteins in our local breed [Baladi]. One hundred and fifty three one day old chicks were used. Our results revealed that there was a significant increase in the levels of total serum proteins, albumin, total globulins and gamma-globulin in the sera of chickens vaccinated with NDVV whereas there was no significant difference between Gumboro vaccinated chickens and control group in the total serum proteins and its fractions. The chickens vaccinated with komarov strain of NDVV showed the highest mean values of total serum proteins, albumin, total globulins and gamma-globulin whereas the lowest values were observed in the chickens vaccinated with Gumboro and Lasota strain of NDVV. Concerning the type of vaccine and weeks post-vaccination. The mean values of total serum proteins, albumin, total globulins and beta-globulins were significantly increased in chickens vaccinated with NDVV either with komarov or Lasota strains at the 1st week post-vaccination. In the 2nd week post-vaccination, the mean values of beta-globulin fraction in group vaccinated with NDVV and chickens vaccinated with NDVV [without last dose] and Gumboro vaccine was significantly decreased. Furthermore, the total serum proteins were significantly decreased in chickens vaccinated with Gumboro and NDVV [K]. In the 3rd week post-vaccinated with Gumboro [L]. It was concluded that the vaccination of chicks with Gumboro vaccine at 14 day of age delay the response of immune system for vaccination with Newcastle disease virus vaccine [NDVV]

Alterations in serum triacylglycerol, cholesterol and lipoproteins fractions in rabbits suffering from chronic hepatic coccidiosis

The effects of chronic hepatic coccidiosis on serum triacylglycerol, cholesterol, high density lipoproteins [HDL], low density lipoproteins [LDL] and very low density lipoproteins [VLDL] were studied in rabbits experimentally infected with Eimeria stiedae. Twenty coccidia-free New Zeal and males 2-3 months of age were used. The animals were divided into two equal groups. The animals in group I [control group] were not infected. Group II was infected by 6000 sporulated oocysts of Eimeria stiedae per rabbit through oral route. Blood samples were collected at 45 days post infection. The statistical analysis revealed that the triacylglycerol, cholesterol, HDL, LDL, and VLDL were highly significantly decreased in rabbits infected with Eimeria stiedae

Effect of dietary cholesterol and olive oil on serum lipids and yolk cholesterol of laying hens

Effect of dietary cholesterol and olive oil on serum lipids and egg yolk cholesterol were investigated. Thirty Hisex brown hens at 25 weeks of age were used in two trials by feeding two basal diets containing 1% cholesterol with or without 10% olive oil. The feeding of cholesterol alone resulted in a significant decrease in serum phospholipids, while cholesterol-olive diet increased its level. In contrast. feeding of cholesterol alone caused an increase in the serum levels of triacylglycerol, total lipids and cholesterol. The previous results were adversed by adding olive oil to cholesterol in the diet. Although, adding of olive oil to diet containing cholesterol leads to a decease in the serum cholesterol level, yet it fails to make the same effect in the egg yolk cholesterol content
