Effect of Feeding Pomegranate Byproduct on Fatty Acid Composition of Ruminal Digesta, Liver, and Muscle in Lambs

Abstract

This work investigated the effects of feeding whole pomegranate byproduct (WPB) to lambs on ruminal, liver, and intramuscular fatty acids (FA). Seventeen lambs, divided into two groups, were fed for 36 days with a cereal-based concentrate diet (CON) or with a concentrate diet containing 200 g/kg DM of WPB to partially replace barley and corn (WPB). The dietary treatment did not affect the final body and carcass weight, the dry matter intake, or the average daily gain. However, total polyunsaturated FA (PUFA), linolenic, rumenic (RA), and vaccenic (VA) acid were increased in liver (+15%, +32%, +344%, and +118%, respectively) and muscle (+46%, +38%, +169%, and +89%, respectively) of WPB lambs (P < 0.05). Punicic acid and three isomers of conjugated linolenic acid were detected exclusively in the rumen and tissues of WPB-lambs. The C18:1 t10/t11 ratio in rumen digesta or in tissues was reduced by feeding WPB (−791%, −690%, and −456%, respectively, in rumen, liver and muscle; P < 0.001), suggesting that the WPB prevented the t10-shift rumen biohydrogenation pathway. In conclusion, the inclusion of WPB into a concentrate-based diet can be a strategy to improve the FA composition of meat, without effects on the animal performances.

Effect of Feeding Hazelnut Skin on Animal Performance, Milk Quality, and Rumen Fatty Acids in Lactating Ewes

“…Immediately after the collection, the rumen content was frozen at −80 • C, freeze-dried, and stored at -30 • C pending analysis. Freeze-dried rumen content was trans-esterified, as described by Natalello et al [3]. Briefly, a freeze-dried rumen sample (250 mg) was added in a centrifuge tube containing C19:0 (Sigma-Aldrch, St. Louis, MO, USA) as an internal standard.…”

“…However, only during the last decades, the research has been focusing on the valorization of agro-industrial wastes as replacers of traditional feedstuffs [1] in order to reduce the environmental impact of livestock productions, especially for ruminants [2]. Including the by-products originating from the agro-industries in animal diets may also enrich their products with biologically active compounds, thus improving the nutritive value and the quality of meat and milk [3,4]. Finally, the use of agro-industrial by-products in animal feeding may be economically advantageous for the industries that could reduce the costs for disposing of the waste biomasses and for the farmers that could attenuate the cost of animal feeding.…”

“…In the literature, some agro-industrial by-products have been recently tested as replacers of human-edible feedstuffs (such as cereals) in the diet of farm animals [3,13,14]. However, it could be reasonable to test a by-product to replace another by-product traditionally used in animal nutrition, especially when its production is more environmentally friendly.…”

“…; film thickness 0.25 µm). Chromatographic conditions were as reported by Natalello et al [37] and fatty acids were expressed as mg/100 g of meat. Atherogenic index (AI) and the Thrombogenic index (TI) were also calculated according to Ulbricht and Southgate [38], in order to evaluate the risk of atherosclerosis and the potential aggregation of blood platelets, respectively.…”
