Carcass characteristics of Santa Ines sheep with different biotypes and slaughtering weights

Abstract

SUMMARY This study evaluated the characteristics of carcass and commercial cuts of Santa Ines lambs of different biotypes (traditional and modern) slaughtered at 32 kg and 34 kg. The thirty-six Santa Ines sheep used, of which 18 traditional and 18 modern biotypes were on average 180 days old and weighed 16 kg initially. The animals were kept in individual stalls (0.80 × 1.20 m) until they reached the slaughtering weight. The experimental design was completely randomized, factorial 2×2 (two biotypes x two slaughtering weights). The traditional biotype influenced significantly (P<0.05) the carcass yields, conformation, and marbling, compared to the modern biotype. The biotype did not influence (P> 0.05) carcass morphometric measurements and commercial cuts. On the other hand, the 34-kg slaughtering weight affected most of carcass characteristics. The traditional biotype displayed higher yield, better conformation and greater amount of intramuscular fat in the carcass. The higher slaughtering weight influenced carcass characteristics and the amount of fat. Generally, the carcasses presented high muscle proportion and fat amount appropriate to the consumer.

Replacement of corn silage with spineless cactus in sheep diet: carcass and meat sensory characteristics

“…The average CCW value of the animals evaluated in this experiment was 15.49 kg, similar to the 14.85 kg reported by Pinto et al (2011), who analyzed the inclusion of spineless cactus in the Santa Inês sheep diet. Carcasses with higher CCW were also the better conformed (p < 0.05), these findings corroborate data of Oliveira et al (2018) in Santa Inês lambs at two slaughter ages.…”

Grape pomace silage on growth performance, carcass, and meat quality attributes of lambs

“…The average finish rate may be due to animal age and the method used for skinning. Fat coverage may have favored higher cooling loss values than the values observed by Oliveira et al (2018) for Santa Inês lambs, since fat deposition reflects cooling loss, higher fat content leads to less water loss during cooling, due to its protective function, preventing losses and improving meat tenderness (Sañudo et al, 2000). The animals in our study were homogeneous, that is, with same ages, weights, and sex and were supplied with rations of similar nutritional value, which may have contributed to the similarity in biometric evaluations and bone, muscle and fat composition, and the compactness index.…”

Performance, eating behavior and carcass characteristics of feedlot lambs fed diets without forage containing sodium bicarbonate

“…The higher ADG of 20SB resulted in higher slaughter weight and, consequentily, higher hot and cold carcass weight for the animals of this group, since carcass weight is directly related to slaughter weight (Oliveira et al, 2018). The weights of neck, shoulder, rib and leg were directly related with the carcass weights, being higher for animals that received 20SB, which in turn produced heavier carcasses.…”
