Effects of different acetylsalicylic acid doses on body organs, histopathology, and serum biochemical parameters in broiler birds

Abstract

The poultry industry suffers from various diseases or stresses. In poultry, apart from being antipyretic, acetylsalicylic acid (ASA) is widely used to cope with different issues including heat stress, and respiratory and digestive orders. This study evaluated the beneficial and toxic effects of ASA at different dose levels in broiler birds. To evaluate these toxic and beneficial effects it is necessary to examine the physical and serum biochemical parameters as well as the histopathological changes with tissue sections taken from broiler birds under experimental trial. This study was conducted on 60 one-day-old broiler chicks purchased from a local market in Faisalabad. Chicks were reared for the first 14 days under similar conditions. On the 15th day, birds were randomly divided into 4 groups (1-4) with 15 birds in each group. Group 4 was kept as control, while groups 1, 2, and 3 were treated with ASA at the dose of 300, 600, and 1200 mg/L of drinking water for 21 days. There were 3 samplings performed at 21, 28, and 35 days post-treatment. The live body weight and carcass weight were noted on each sampling. All the visceral organs were recorded for gross pathological changes. The serum samples were collected for biochemical evaluation. Histopathology of all the visceral organs was performed to observe the microscopic changes. A significant (P<0.05) increase in live body weight at a 300mg/L dose was noted after the first 2 samplings. A significant (P<0.05) increase in the relative organ weight was recorded at 1200 mg/L. The groups treated with ASA 600 and 1200 mg/L showed increased (P<0.05) AST, ALT, and creatinine levels from that of the control group. The group treated with 1200 mg/L of ASA showed increased (P<0.05) urea, serum total protein, and albumin level in all the samplings. Histopathological changes revealed swollen hepatocytes, increased sinusoidal spaces in the liver, congestion and abnormal glomerular spaces in the kidney, congestion and alveolar disruption in the lungs, and generation of villi and cellular degeneration in the intestine in a high-dose group. The study concluded that ASA at a low dose can be used for a long time in broilers and has a growth promontory role, while high-level doses cause hepatorenal toxicity.

Sodium Salicylate as Feed Additive in Broilers: Absence of Toxicopathological Findings

“…Concerning histopathological evaluations, although studies have shown that ASA promotes lesions in the small intestine [38,47], lungs, liver, and kidneys [38], in the present study, no significant alterations were detected in any of the tissues evaluated. This result agrees with those of previous studies [17,49].…”

“…A search in the literature to provide data about the beneficial use of ASA supplementation in the diets of birds under different stress conditions [30][31][32][33][34][35] or not [36][37][38] revealed inconsistent results between the different studies, and no clear conclusion could be reached [15]. It should be noted that, in all these studies, authors have incorporated ASA into drinking water or feed; however, no descriptions about the condition and storage time, as well as the replacement of the feed/drinking water after incorporation of the salicylate until their consumption, were provided.…”

Toxicity of different doses of Diclofenac in Black Kites

“…Kidney portions from the diclofenac group exhibited substantial congestion, intertubular brosis, lymphoid aggregation, and tubular architectural disturbance. Histopathological abnormalities in a high-dose group showed obstruction, wide sinusoidal gaps in the kidney, distortion of the kidney's glomerular ltrate area, disruption of the lungs at the alveolar level, necrosis, and villi formation in the gut [22].…”
