“…The reason of increase the fat tail act as the amino acids are used as intermediate components in the production of fatty acids, which can be used for acetyl-CoA production and then in synthesis biochemical of fatty acids (Kiounarsi et al, 2008). Our result has agree with the results of Kiounarsi et al (2008), but do not agree with Obeidat et al (2008) may be because they used only methionine but not a mixture of amino acids like present study. No significant (P<0.05) differences were presented in the weights of lion, heart, liver, lungs and kidney between groups.…”

“…However, the local sheep has dropped in wool characterizes performance less than other breeds sheep in the world, this due to the genotype factor which may affect on the capacity of wool growth by many pathways, for example the skin mass and the ability of follicle to use amino acids (Adams et al, 2000). Table (5) showed a significant (P<0.05) increased in carcass characterizes such as Slaughter weight, hot carcass weight, Shoulders, legs and fat tail in in lambs treated with 10g/ head of a mixture of amino acids compared with T2 and control groups, due to the provide amino acids for animals will alter the fermentation process in the paunch resulting a rise in the synthesis of microbial protein and fatty acids production, those alterations caused more improve in the amount of protein available and energy balance which led to a rise in body growth (Kabir, 2009;Khorshidi, 1996). So, when body growth improve absolutely will reflect positively on the carcass characterizes performance.…”

“…However, the effect of increased dietary energy levels on ADG has been less consistent. In some instances ( Craddock et al, 1974 ; Lu and Potchoiba, 1990 ; García et al, 2003 ), increasing the energy level had no effect on the ADG, whereas in others ( Kioumarzi et al, 2008 ; Adbel-Basset, 2009 ), an increase in energy level markedly increased the ADG. In most cases, when growth performance was compared among dietary energy concentrations below 2.6 Mcal/kg ME, the ADG and feed efficiency increased as energy increased.…”

“…The energy level did not influence ADG (p≥0.23), however, the lambs fed high-energy diets showed an increase in gain to feed (8.1%) as a consequence of differences in DM intake. Increases in feed efficiency have been a common response when comparing high-energy and low-energy diets ( NRC, 2007 ; Kioumarzi et al, 2008 ; Adbel-Basset, 2009 ). However, the effect of increased dietary energy levels on ADG has been less consistent.…”

Forty-eight Pelibuey×Katahdin male intact lambs (23.87±2.84 kg) were used in an 84-d feeding trial, with six pens per treatment in a 2×2 factorial design arrangement. The aim of the study was to evaluate the interaction of two dietary energy levels (3.05 and 2.83 Mcal/kg ME) and two dietary protein levels (17.5% and 14.5%) on growth performance, dietary energetics and carcass traits. The dietary treatments used were: i) High protein-high energy (HP-HE); ii) High protein-low energy (HP-LE); iii) Low protein-high energy (LP-HE), and iv) Low protein-low energy (LP-LE). With a high-energy level, dry matter intake (DMI) values were 6.1% lower in the low-protein diets, while with low-energy, the DMI values did not differ between the dietary protein levels. Energy levels did not influence the final weight and average daily gain (ADG), but resulted in lower DMI values and higher gain efficiencies. No effects of protein level were detected on growth performance. The observed dietary net energy (NE) ratio and observed DMI were closer than expected in all treatments and were not affected by the different treatments. There was an interaction (p<0.03) between energy and protein level for kidney-pelvic and heart fat (KPH), KPH was higher in lambs fed high energy and high protein diet but not in high energy and low protein diet. The KPH was increased (20.2%, p = 0.01) in high-energy diets, while fat thickness was increased (21.7%, p = 0.02) in high-protein diets. Therefore, it is concluded that dietary energy levels play a more important role in feed efficiency than protein levels in finishing lambs with a high-energy diet (>2.80 Mcal/kg ME). Providing a level of protein above 14.5% does not improves growth-performance, dietary energetics or carcass dressing percentage.

“…The higher energy value of diets containing 42% forage cactus resulted in more leg fat, the higher percentage of fat in the leg can be attributed to the higher energy intake, caused by the higher dry matter intake observed also in the higher slaughter weight provided by cactus silage. According to Kioumarsi et al [41], the simultaneous increase in dietary energy and protein levels in ruminants is related to an increase in amino acids used as pre-glycolytic components in the production of acetate, which can be used to produce acetyl-CoA and, in turn, for the biosynthesis of fatty acids.…”

Carcass traits and meat quality of lambs fed with cactus (Opuntia fícus-indica Mill) silage and subjected to an intermittent water supply

et al. 2020

The present study aimed to evaluate the effect of cactus silage and an intermittent water supply for lambs on carcass traits and meat quality. Thirty-six crossbreed lambs with an initial average weight of 19.8 ± 2.1 kg and average age of 6 months were randomly assigned to a 3 × 3 factorial design comprising three addition ratios of cactus silage to the diet (0, 21, and 42% based on dry matter) and three water supply intervals (0, 24, and 48 h) with four replicates. There was no interaction (P > 0.05) between the cactus silage ratio and intermittent water supply for any of the evaluated variables, with the exception of the yield of the half carcass commercial cuts. There was no significant effect of intermittent water supply (P > 0.05) on the carcass characteristics or meat quality. The addition of forage cactus silage as a substitute for Tifton hay affected the morphometric measurements (P < 0.05) and carcass compactness index (P < 0.05). The addition of 42% cactus silage to the diet increased (P < 0.05) the rib eye area (13.98 cm 2). The addition of cactus silage as a substitute for Tifton hay positively affected (P < 0.05) the carcass weight of commercial cuts of the lambs. To the physical and chemical parameters of the Longissimus lumborum, the addition of 42% cactus silage to the diet reduced the color meat parameters (P < 0.05) and pH 0 and 24h , cooking losses, and shear force were not affected (P > 0.05). The addition of forage cactus silage to the lambs' diet affected (P < 0.05) the composition of some saturated fatty acids in the meat. A water supply interval of up to 48 h does not influence carcass characteristics and meat quality. Therefore, the use of cactus silage can be recommended in situations of water scarcity without harming the production or meat quality of crossbreed lambs.
