Effects of by-product from biscuit industry on performance and carcass traits of fattening Morada Nova lambs

This research evaluated the effects of using by-product from biscuit industry (BBI) in the diet of fattening lambs of Morada Nova breed. Lamb growth performances and carcass traits were investigated. Twenty Morada Nova breed male lambs body weight (BW) 17.1 ± 3.74 kg, single born, and age 141 ± 7 da...

Description
Summary:This research evaluated the effects of using by-product from biscuit industry (BBI) in the diet of fattening lambs of Morada Nova breed. Lamb growth performances and carcass traits were investigated. Twenty Morada Nova breed male lambs body weight (BW) 17.1 ± 3.74 kg, single born, and age 141 ± 7 days were divided into four homogeneous groups ( n  = 5) fed for 8.5 weeks with four experimental diets replacing corn with BBI at 0, 150, 300, and 450 g/kg. Experimental diets were consisted of 30% Tifton-85 hay and 70% concentrate on dry matter (DM) basis. Diets were formulated to be isonitrogenous and isoenergetic in order to supply nutrient requirements of growing lambs with an average daily gain of 200 g/day. Increased feeding levels of BBI partially replacing corn did not affect dry matter intake, organic matter, and crude protein intake ( P  > 0.05). Animal performance was not affected by the dietary treatments ( P  > 0.05). BBI addition to the concentrate did not influence carcass traits, carcass measurements, quali-quantitative of Longissimus lumborum muscle, and meat cuts ( P  > 0.05). Partially replacing corn with a by-product from biscuit industry does not affect performance and carcass traits of fattening lambs. The BBI can partially replace up to 450 g/kg DM of corn on lambs’ diets as a suitable agro-industrial by-product.
