“…Wool and skin represent the most valuable non-carcass components, making up 10 to 20% of total animal value (Camilo et al, 2012;Pompeu et al, 2013). This important source of revenue leads producers to improve herd sanitary conditions, thus increasing product quality (Santos et al, 2015).…”

We evaluated performance, non-carcass components, and carcass characteristics of crossbred Texel lambs in different categories of residual intake and gain (RIG). We assessed 77 crossbred (¼ Pantaneira and ¾ Texel) non-castrated animals in two study phases. The first phase included 47 lambs with an initial average weight of 29.9±5.5 kg, and the second phase included 30 lambs with initial average weight of 22.4±3.3 kg. Dry matter intake (DMI) and average daily gain (ADG) were evaluated for 70 days. Animals were divided into three groups in terms of efficiency: efficient (high RIG), intermediate (medium RIG), or inefficient (low RIG), based on the standard deviation of the mean for the RIG variable. We measured the yield of noncarcass components, carcass characteristics, and yield of meat cuts. Efficiency group had no association with DMI, nor with initial and final body weights of the animals. The ADG of efficient (0.310 kg day −1 ) and intermediate (0.290 kg day −1 ) animals was greater than observed in inefficient (0.260 kg day −1 ) animals. Lambs in the efficient and intermediate groups had significantly higher levels of all efficiency indicators evaluated. Efficient and intermediate animals yielded significantly more wool/skin in comparison with lambs in the inefficient group. Animals with high RIG also had lower relative weight of testicles/scrotal sac in comparison with inefficient animals. Fat deposition in the omentum and mesentery as well as total fat were decreased in efficient animals. No significant differences occurred among groups regarding carcass characteristics and yield of meat cuts. The RIG index allows for the identification of lambs with higher growth rates and greater wool/skin yield and lower proportion of visceral fat.

In addition to influencing performance, the use of new ingredients in the diet of production animals can influence meat quality. Were used 15 lambs, crossbred from Dorper x Santa Inês, divided into three experimental groups. Group 1 (Control) fed with Tifton hay and concentrate, in the proportion of 40:60; Group 2- animals fed a 100% high grain diet; Group 3- lambs fed with Tifton hay and concentrated with the inclusion of 6% residual frying oil. After 40 days of confinement, the animals were slaughtered and the Longissimus dorsi muscle was removed from the carcasses for analysis of meat quality attributes. There was no effect of the test diets (P > 0.05) on the physical parameters of the meat. The protein and lipid values were higher in the meat of the animals on the diet with residual oil. The moisture content of meat from animals on the high-grain diet showed higher values (P < 0.05) than that of other diets. This fact is attributed to the lower muscle development in animals on this diet, which may also have contributed to the levels of meat protein and lipids in this treatment. It was concluded that the diet with the inclusion of frying oil was the best among the test diets because it did not negatively impact the meat quality.
