Concentrate Level

The objectives of this experiment with Hereford (Hf) and Charolais (Ch) bulls offered grass silage-based diets were to determine the effects on performance, carcass traits and meat quality of the proportion of concentrate in the diet, and the inclusion of rapeseed meal (RSM) in the barley-based concentrate. The two concentrate proportions were 200 and 500 g kg-1 dry matter, fed without or with RSM. The Ch bulls tended to achieve higher gain, produced less fat, had a higher percentage of meat from high-priced joints and had a lower degree of marbling in their meat compared to the Hf bulls. Dry matter and energy intakes, growth performance and carcass conformation improved with increasing concentrate level. Intake parameters and conformation improved more with the Ch bulls than with the Hf bulls as a consequence of increased concentrate allowance. RSM had only limited effects on the performance, carcass traits or meat quality.

<p>The objective of this study was to evaluate the effect of rearing system (confinement, C <em>vs </em>semi-confinement, SC) and sex (barrows <em>vs </em>females) on growth performance, carcass traits and meat quality of “Criollo negro de la costa ecuatoriana” pigs. A total of 32 pigs, 16 barrows and 16 gilts were used. The average daily gain (0.30 kg/day <em>vs </em>0.22 kg/day), slaughter weight (51.4 kg <em>vs </em>43.1 kg), morphometric parameters and weights for the most valuable meat cuts were higher in C pigs than in SC pigs, whereas hot and cold carcass yields were higher in SC pigs than in C pigs. The loin and sirloin percentages from C pigs were lower and higher compared with those SC pigs, respectively. Carcass of C pigs showed higher percentage of fat and lower percentage of lean and bone that SC pigs. The rearing system had scarce effects on meat quality traits and mineral composition. Meat from C pigs showed lower scores for color, brightness, and unctuousness, and higher for metallist taste, juiciness and persistence of flavor than SC pigs. Few sensory attributes of cooking chops were affected by sex. Metallist taste was higher in barrows, while brightness and lard flavor were higher in females. It can be concluded that the rearing system had a significant effect on most of the productive and carcass traits, whereas its effect was limited on the meat traits. Sex had little influence on most of the traits studied.</p>

Abstract The objective of this study was to evaluate the effects of supplementing low-protein diets with sodium dichloroacetate (DCA) and glucose on growth performance, carcass traits, and meat quality of growing-finishing pigs. A total of 80 crossbred (Duroc × Landrace × Large White) growing barrows (27 ± 0.4 kg body weight) were allocated randomly to one of the five treatments during three successive 4-week periods. There were five diets in each phase. Diet 1 was the control diet with normal protein levels (CON) where protein levels in the three phases were 18%, 16.5%, and 15.5%, respectively. The dietary protein levels of Diets 2, 3, 4, and 5 (the low-protein diets, LP) were decreased by 4.5% compared to Diet 1. Additionally, Diets 3 and 4 were supplemented with an extra 120 mg/kg DCA (LP + DCA) or 1.8% glucose (LP + GLUC), respectively. Diet 5 was further supplemented with an extra 120 mg/kg DCA and 1.8% glucose (LP + DCA + GLUC). The LP + DCA diet increased the average daily weight gain of pigs compared to the CON and LP diet in phase 3 and the overall experimental period (P &lt; 0.001). The LP diet reduced the gain:feed ratios of the pigs compared to the CON, LP + DCA, and LP + DCA + GLUC diets in phase 1 and the overall experimental period (P &lt; 0.001). Furthermore, gain:feed ratios in LP + DCA and LP + DCA + GLUC groups did not differ from that of the CON group (P &gt; 0.10). Pigs fed the LP + DCA diet had higher pH values of meat at 24 h post-mortem than the CON group (P &lt; 0.05). The LP + DCA + GLUC diet increased the total protein content in the longissimus dorsi (LD) muscle of pigs, compared to the other dietary treatments (P &lt; 0.05), and increased the Arg and Leu contents in the LD muscle compared to the LP + DCA diet (P &lt; 0.05). Moreover, the LP + DCA diet induced a higher C18:1n9t percentage in the LD muscle of pigs compared to other groups (P &lt; 0.05). In conclusion, an LP diet reduced the feed efficiency in pigs and barely affected meat quality, whereas 120 mg/kg DCA supplementation in an LP diet improved the growth performance of growing-finishing pigs, showed modest effects on carcass traits, and improved the muscle protein content with the addition of glucose.

Nutritional Restriction

The objective of the present study was to investigate the effect of nutritional restriction during the suckling period on growth performance, carcass traits and meat quality of fattening pigs. A one-way experimental design was used. In total, 24 male pigs of normal birthweight (1.54 ± 0.05 kg) were randomly allocated at 7 days of age to three groups: control, fed ad libitum; 30% nutritional restriction (Re30%); and 60% nutritional restriction (Re60%). The Re30% and Re60% groups showed decreased average daily gain, average daily feed intake and feed conversion ratio from Day 7 to Day 28. After Day 28, differences in these parameters were observed only in the Re60% group relative to the control. With regard to hormone levels, the Re60% group showed decreased serum concentration of insulin-like growth factor-1 at Day 28 and increased serum concentration of growth hormone at Day 147. Furthermore, the Re60% group had decreased carcass weight, ham weight and dressing percentage, and increased carcass lean percentage relative to the control, as well as lower cross-sectional area and myofibre diameter of muscle. The Re60% group had lower levels of myosin heavy chain (MyHC) IIx and MyHC IIb mRNA and a higher percentage of MyHC I and MyHC IIa mRNA in longissimus dorsi muscle than the Re30% group. In conclusion, nutritional restriction during the suckling period decreased weaning weight, with post-weaning growth performance, carcass traits and myofibre type affected in the Re60% group rather than Re30% group.
