“…A bone yield similar to that found here (18%), though associated with a lower muscle yield (50.9%) and a much higher fat yield (30%) was found by Carvalho & Medeiros (2010) for a lower-quality carcass than was observed in this research.…”

Tissue composition of the leg and meat quality of sheep fed castor bean hulls in replacement of tifton hay

et al. 2013

-The effects of replacing Tifton hay with castor bean hulls (0, 33, 66 and 100%) on the leg tissue composition, chemical composition, physicochemical parameters and sensorial traits of sheep meat were studied. A total of 28 non-castrated sheep averaging seven months in age with an average initial weight of 19.5±4.3 kg were assigned to a randomized block design with four treatments and seven replicates and were slaughtered after 70 days of confinement. At slaughter, body weight and leg, muscle and bone weights decreased linearly, whereas the muscle-to-bone ratio increased linearly according to the treatments. There was a quadratic effect on yellow intensity (maximum of 8.05 with replacement of 54.5%) and the percentage of cooking losses (minimum of 33.8% with replacement of 45.17%). The treatment employed did not affect either the chemical composition or sensorial traits of the lamb meat. Although replacing Tifton hay with castor bean hulls alters the tissue composition of the leg as well as some physicochemical parameters of the meat, the sensory analysis indicated good acceptability of the meat, regardless of the inclusion of this byproduct.

“…The average HCY (49.4 kg/100 kg SBW) found for non-castrated male lambs (¾ Texel + ¼ Pantaneiro) in our study was higher than that reported by Carvalho and Medeiros (2010) for non-castrated male lambs (½ Texel + ½ undefined; 47.4 kg/100 kg SBW). Lima et al (2013) also published HCY (48.7 kg/100 kg SBW) and CCY (47.2 kg/100 kg SBW) for male Texel lambs that were lower than those found in the present work.…”

“…Therefore, the higher ADG of efficient animals may have resulted from lower maintenance energy expenditure in fat tissue synthesis. Lamb internal fat has no use for human consumption; thus, fat deposition directs energy away from the production of components with commercial value (Carvalho and Medeiros, 2010;Moreno et al, 2014).…”

Residual intake and gain for the evaluation of performance, non-carcass components, and carcass characteristics of confined crossbred Texel lambs

et al. 2019

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.

“…There were no significant differences in heart and respiratory organ weights between the four treatments, because these organs maintain its integrity due to the priority of nutrient utilization, independently of feeding. This effect was also observed by Carvalho and Medeiros (2010) who used diets with different energy levels the authors found no difference between treatments for organ weights. These results corroborate with those found by Cutrim et al (2012), this may likely be due to the similar age and initial and slaughter weights of animals.…”

The byproducts of agricultural processes have great potential as a source of low cost animal feed. In this paper we assess the potential of açaí palm (Euterpe oleracea Mart.) seed as a food source for sheep. Sixteen non-castrated male sheep with average initial body weight of 22 kg were randomly assigned to one of four diet treatments, using initial body weight as a covariate. The diets consisted of coastcross hay and a variable proportion of açaí seed meal (0, 5, 10 and 15% -DM basis) added to feed concentrate at a ratio 60:40 (roughage:concentrate). The animals were slaughtered at the end of the experiment to measure carcass and commercial cuts dressing of each animal. No treatment effect on carcass, commercial cuts and non-carcass components dressing was detected, but significant effect on daily weight gain and shoulder dressing was observed. Açaí seed meal added to the diet up to 15% in replacement with forage during dry seasons does not seem to compromise carcass and non-carcass components and is therefore a potentially valuable and low cost component of sheep feed.
