The experiment was conducted on 2640 slow-growing (NL-JA-757) broiler chicks divided into three groups with eight replicates of 110 chicks each for period of 49 days. The control group was fed diets without any color additive, while experimental groups A and B were fed diets containing commercial color additive (0.05%) and sea buckthorn fruit residue 5% of feed respectively. Diets BR1 (starter) were fed from day 1 to 21; BR2 (grower) were fed from day 22 to 35, and BR3 (finisher) were fed from day 36 to 49. The chicks were weighed on days 21, 35 and 49. The final mean live weight of the birds (males and females) appeared lower in group B with sea buckthorn in comparison with the control group (1848.1 vs.1875.5g) and group A (1882.5g). Feed conversion at 49 days was poorer in group B (2182.6 g/kg) in comparison with group A (2102.4g/kg) and non-significantly poorer than the control group (2163.7 g/kg). Skin color was assessed by the DSM Broiler Fan expressed on a 101–110 scale. The skin of the birds was more yellowish in group A (104.4) in comparison with group B (103.0) and the control group (102.5). Neither the health of the birds nor their mortality was affected by the diets. © 2014, Indian Journal of Animal Research. All Rights Reserved. Source

Pathology, research and practice

Non-alcoholic-fatty-liver-disease (NAFLD) is a clinicopathologic entity characterized by a variety of hepatic injury patterns without significant alcohol use. It has a close association with obesity, so treatment includes weight loss, control of insulin sensitivity, interventions directed at inflammation and fibrosis. There is a certain relationship between the grade and duration of food restriction and hepatic function. The objective of this work was to describe the relationship between biochemistry, autoantibodies, insulin-like growth factor I (IGF-I), insulin-like growth factor binding protein 3 (IGFBP-3), and liver morphology in experimental rabbit groups with food restriction as compared to controls with ad libitum food (ADL) income. The experiment was performed on a total of 24 rabbits of a weaning age of 25-81 days. The first group (R1) was restricted between 32 and 39 days of age to 50 g of food per rabbit a day. The second group (R2) was also restricted between 32 and 39 days, but the rabbits received 65 g of food per rabbit a day. At the end of the experiment, the blood and liver samples were collected at necropsy. NAFLD has developed in all three groups. There was any autoantibody positivity in all three groups. IGF-I is moderately higher in R1 and R2 group, as compared to the control group (P > 0.05). IGFBP-3 is without statistical significance in all three groups. Alkaline phosphatase (ALP) is the only liver biochemical parameter that has significantly increased following food restriction (P > 0.039). Single one-week restriction has any protective effect on NAFLD development. Copyright © 2014 Elsevier GmbH. All rights reserved. Source
