Feeding of Camelina sativa Seeds to Light-Type Gentile di Puglia Lambs: Effect on Productive Performance and Muscle Fatty Acid Composition

The effect of different amounts of camelina (CAM; Camelina sativa) seeds in lambs of the Gentile di Puglia breed on growth, carcass characteristics, and meat quality was investigated. Up to 70 days of age, twenty-four male lambs (13.0 +/- 0.35 kg) were randomly assigned to three isocaloric and isonitrogenous diets. Pelleted total mixed rations (TMR) were created to provide: (1) a control diet (CON), (2) an experimental corn-based diet including 5% camelina (CAM5) seeds, and (3) an experimental corn-based diet containing 10% camelina (CAM10) seeds. The presence of CAM in the diet impacted lamb performance (p < 0.05), according to the results of a growth study. Lambs were slaughtered at the conclusion of the feeding period, and none of the carcass characteristics investigated were significantly affected by dietary treatment, with the exception of brisket and rib weight and carcass lean, which were improved (p < 0.05) in lambs fed the CAM diet. The color of lamb flesh from the Longissimus lumborum muscle was affected by CAM diets (p < 0.05), but the chemical content and physical characteristics did not differ across treatments (p > 0.05). The fatty acid composition of lamb meat in muscle was somewhat regulated by the experimental diets, with CAM feeding improving (p < 0.05) the level of linolenic acid and MUFA while reducing SFA and PUFA. As a result of the current data, it can be stated that camelina seed supplementation may be included in the lamb diet because no negative impacts on productivity, as well as an enhancement in meat quality, have been found.
