Responses of Nili-Ravi buffalo to aflatoxin B1 with and without toxin adsorbents
Journal Title: Journal of Animal and Feed Sciences - Year 2014, Vol 23, Issue 4
Abstract
The objective of the study was to determine the responses of Nili-Ravi buffalo to aflatoxin B1 (AFB1) in terms of feed intake, haematological and serum biochemical parameters and to compare the efficacy of three different toxin adsorbents against AFB1. Twenty-five Nili-Ravi buffaloes were selected from a herd and were divided into five groups for a period of 21 days to receive: no aflatoxin B1 (AFB1) in the diet, a diet contaminated with AFB1, a diet contaminated with AFB1 with the addition of one of three different toxin adsorbents: glucomannan, hydrated sodium calcium aluminosilicate (HSCAS), or activated charcoal at an inclusion level of 0.2% of feed. AFB1 was incorporated into feed at an inclusion level of 500 µg · kg–1 per animal per day. The results indicate that the average daily feed intake of AFB1-treated buffaloes significantly declined (P < 0.05) compared with the control. Serum levels of total bilirubin, alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST) and creatinine were significantly increased (P < 0.05) in response to AFB1, but the change in blood urea nitrogen (BUN) levels was nonsignificant (P > 0.05). In haematology, the total erythrocyte count (TEC), total leukocyte count (TLC), haemoglobin concentration (HGB), haematocrit levels (HCT), mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC) decreased significantly (P < 0.05) in the AFB1 group on days 14 and 21 of the experiment. From among the three toxin adsorbents, 0.2% glucomannan significantly (P < 0.05) improved the feed intake levels of buffaloes and also significantly (P < 0.05) minimized the AFB1-induced adverse effects on haematology and serum biochemistry, but was unable to totally ameliorate its effect, while HSCAS was less effective, and activated charcoal, the least.

Polymorphism of the pig LMX1A gene, localized within the FAT1 region, is not associated with growth and fatness
The LMX1A gene, located within the 3.3 cM FAT1 QTL on porcine chromosome 4, was tested as a positional and functional candidate for fatness traits. A gene fragment consisting of the partial promoter, 5’UTR, exon 1, and p...
