“…Similarly, no difference was noted in these parameters between the treated groups. Partially similar results were reported by Carrasco et al (2009) and Jacques et al (2011) in the fat tissue of animals raised on pasture. Fat deposition in the animal body is affected by feeding system (Jacques et al, 2011).…”

“…Fat deposition in the animal body is affected by feeding system (Jacques et al, 2011). The colour variations in meat may be the consequence of the amount of green carotenoids stored in the meat (Carrasco et al, 2009). The results of the present study are important from the point of view of consumers satisfaction, as they are more interested in purchasing lean meat.…”

-Forty male Naemi lambs were used to evaluate the effect of total mixed rations (TMR) alone or in combination with supplementation of alfalfa hay offered at different schedules on growth, carcass characteristics, and meat quality. Lambs at the age of three months, with an average weight of 28.85±1.09 kg, were randomly selected and distributed into four different feeding systems, 10 lambs each, as follows: TMR diet (control); TMR plus 100 g alfalfa hay; TMR plus 200 g alfalfa hay every two days; and TMR plus 300 g alfalfa hay every three days. The TMR and fresh drinking water were offered ad libitum. Lambs in the treated groups (with alfalfa hay) had significantly higher body weight, body weight change, dry matter intake, and feed conversion ratio compared with the control. Similarly, slaughter weight, carcass weight (hot and cold), and internal organs weight significantly increased in the treated groups, except for dressing weight percentage, which improved only in the treatment with TMR plus 300 g alfalfa hay. By contrast, mesentery fat, back fat, and body wall fat decreased in treated groups. Meat quality characteristics indicated that cooking loss and pH values did not differ between the control and treated groups; however, meat colour (lightness, yellowness, and redness) and pH (1 and 24 h) improved in postslaughter treated groups. Furthermore, no difference was found in texture profile analysis (hardness, springiness, cohesiveness, and chewiness), although the shear force decreased significantly in treated groups. Addition of alfalfa hay offered at the present plan may not only improve the growth and carcass characteristics, but also enhance the meat quality of Naemi lambs. From the labour and economic point of view, TMR plus 300 g alfalfa hay every three days may be adopted while taking into account the management decision.

“…However, alfalfa-fed lambs (which can be considered as a positive control for animal health and welfare) had lower growth rates and higher feed-to-gain ratios than animals in the other groups. These differences are on account of the higher fibre and lower protein and energy intakes in alfalfa-fed lambs as compared with concentrate-fed animals, in agreement with Carrasco et al (2009a and2009b), Papi et al (2011) and Tufarelli et al (2011).…”

“…As a result, using pelleted diets may have no positive effects on rumen physiology, the consequences for animal health being even more detrimental than those from the traditional feeding system due to a decrease in physically effective fibre contents (Zhao et al, 2011). So far, the best strategy to promote optimal rumen fermentation is the use of forage-based rations, although it is known that the feed-togain ratio and average daily gain may be worsened as compared with concentrate-based rations (Carrasco et al, 2009b;Tufarelli et al, 2011). In a previous work, Blanco et al (2014) showed that it is possible to fatten light lambs on a TMR pellet including ground barley straw and enhance animal performance without modifying meat characteristics compared with the traditional feeding system for these animals in Mediterranean countries, based on concentrate and long-form barley supplied separately.…”

Fifty male Merino lambs (6 to 8 weeks, 14.1 kg; n = 10 per group) were used to study the effect of feeding system: barley straw in long form and concentrate pellets in separate troughs (Control), ad libitum alfalfa supplemented with concentrate in separate troughs (Alfalfa) or including various levels of ground barley straw in concentrate pellets (B05, B15 and B25 for 50, 150 and 250 g barley straw/kg), on rumen characteristics, acid-base status, blood cell counts and lymphocyte stimulation. Alfalfa lambs had the heaviest digestive tract contents, highest rumen pH values, lowest volatile fatty acid concentration, highest papillae counts and best mucosa colour and the greatest blood pCO 2 values, lowest sodium and chloride and highest potassium concentrations (P < 0.05). Including ground barley straw in the concentrate pellet or providing straw in long form separately from the concentrate reduces rumen pH and darkens ruminal mucosa as compared with alfalfa-fed lambs, thus affecting acid-base status.

“…Previous studies that predominantly compared pasture vs. grain feeding indicated that growth performance and carcass characteristics (Carrasco et al, 2009b;Ripoll et al, 2008), meat quality traits, such as color (Priolo et al, 2001;Ripoll et al, 2008), water-holding capacity (WHC) (Santos-Silva et al, 2002b), sensory characteristics (Duckett et al, 2013;Fisher et al, 2000), fatty acid (FA) profile (Karaca and Kor, 2015;Nuernberg et al, 2008), and oxidative stability (Popova, 2007), can also be affected by feeding systems. In general, pasture-fed lambs have leaner carcasses, lower dressing percentage, and more Pastures plays a very important role in small ruminant breeding and in extensive animal feeding, which is common practice in Turkey, where supplementation of lambs with commercial concentrate is limited.…”

The effect of feeding system on slaughter-carcass characteristics, meat quality, and fatty acid composition of lambs

Abstract. In this study, we aimed to determine the slaughter-carcass characteristics, meat quality, and fatty acid composition in lambs raised under intensive and extensive conditions. The animal material consisted of 30 Norduz male lambs, with an average age of 171 days. The lambs were divided into two groups: concentrate-fed lambs (CO) and pasture-fed lambs (PS). The results showed that the CO lambs had heavier carcasses (p< 0.001), a higher dressing percentage (p< 0.001), and higher intramuscular fat (p< 0.01) than the PS lambs. It was determined that the longissimus thoracis muscle of the CO lambs had a lower ultimate pH and higher L * and water-holding capacity than the PS lambs. In this study, intramuscular fat (longissimus thoracis, semimembranosus, triceps brachii), subcutaneous and tail fat samples were used to evaluate the effect of feeding system on fatty acid composition. The polyunsaturated fatty acid to saturated fatty acid ratio (PUFA / SFA) of intramuscular fat was found to be significantly higher in the CO group than in the PS lambs, while similar subcutaneous and tail fat results were found in both groups. Moreover, the PS lambs had a lower n6 / n3 ratio and higher percentage of omega-3 than the CO lambs in all tissues studied (p< 0.05). Overall, the CO lambs have heavier and fattier carcasses with better meat quality traits than the PS lambs. However, the effects of feeding system have varying results based on the fatty acid composition of different types of fat deposits.
