“…In research done by Jaeger et al (2004) and Garcia et al (2010), evaluating diets with or without protected fat, the authors found no significant difference in hot carcass weight and carcass yield. Homem Junior (2008) noted that the hot carcass yield was higher in the carcass of lambs consuming the protected fat diet (48.5%) compared with the control diet (46.5%); however, the cold carcass yield did not differ between treatments.…”

“…Except for chest depth, the inclusion of fat source in the diet resulted in the same for Garcia et al (2010) and Manso et al (2009), who included fat sources in lambs diet and found no differences for these characteristics. Awawdeh et al (2009) also found no differences for carcass measures, except for subcutaneous fat thickness, which increased with the use of fat source in the diet.…”

-This experiment aimed to determine the influence of diets with inclusion of protected fat and vitamin E on performance, yield and carcass characteristics of feedlot lambs with different weights. Thirty-two non-castrated Santa Ines lambs were fed diets with a ratio of 40% forage and 60% concentrate ad libitum, with presence or absence of protected fat and/or vitamin E, in a total of four diets. Two weights of early containment were also considered: between 20 and 25 kg and between 30 and 35 kg. All animals were slaughtered at 84 days of confinement. Animals fed diets without addition of protected fat, regardless of the use of vitamin E, had the highest intakes of dry matter, crude protein, neutral detergent fiber and ash, and decreased intake of ether extract. The variables investigated did not affect daily weight gain and total gain. Feed conversion was better for the lighter confined animals not fed protected fat. The heavier feedlot lambs fed diets with vitamin E showed higher cold carcass. The warm carcass for the lighter animals confined fed with vitamin E, and the heavier ones, fed with protected fat and vitamin E, showed the best yields of cold carcass. Objective measures of the carcass cold had the highest mean for heavier feedlot lambs. The addition of fat in the diet reduces the intake of dry matter and increases the ether extract.Although the inclusion of vitamin has no effect on intake of nutrients, it protects the carcasses from losses during cooling, and weight differences at containment directly reflect the measures of the carcasses.

“…The effect of feed regime on rack weight was not significant. Overall mean of neck weight was lower than Kermani male lambs (1.69±0.244 kg, Shahrbabak et al, 2009), Santa Inês lambs (1.59 kg, Garcia et al, 2012) and Ossimi (1.08±0.05 kg, Abdel-Moneim, 2009). Effects of feed on neck weight were not significant.…”

Feeding on white or black whole barley grain and fattening period's effect on the body weight and measurements, as well as carcass quality of Karadi male lambs was investigated in this study. A total of sixty Karadi male lambs aged six month-old was randomly allocated to two feeding systems (white or black barley grain) for four periods of experimental fattening trial (each period was one month). Body weights as well as total body gain for lambs fed white barley were significantly (P<0.05) higher than lambs fed black barley during experimental periods. Feeding white barley significantly (P<0.05) increased body length at eight-month (second period), nine month (third period) and final weight (fourth period) compared to black barley. Moreover, height at withers and heart girth showed significant differences at the final period (age of 10 th months). Result showed a high interaction between fattening periods and feeding regimes on the length of body, wither height and the girth of heart. This may indicate that lambs at different experimental periods responded differently to type of barley. It is concluded that body weights, total body gain and body measurements for lambs fed white barley were significantly higher than lambs fed black barley.
