“…Greater protein deposition was detected in the body of pigs previously restricted with protein (lysine) intake and the site of this deposition was mostly in the carcass (Skiba, 2005), which was in agreement with the findings of our study. Moreover, the lipid content in lysine-restricted pigs was lower compared with continuously well-fed pigs.…”

The effects of lysine restriction during grower phase and realimentation during finisher phase on growth performance, nutrient digestibility, blood metabolites, carcass traits and pork quality were studied. Sixty-four pigs (two castrated males and two females per pen) weighing 34.3495.22 kg were assigned to four dietary treatments. During grower (35Á55 kg), pigs were fed isoenergetic lysine-restricted diets. The different lysine content of diets were 0.950 (NRC recommendation), 0.760, 0.665 and 0.570%, corresponding to lysine restriction of 20, 30 and 40%. Then all pigs were fed with common finisher 1 (55Á85 kg) and 2 (85Á115 kg) diets. Lysine restriction during the grower phase resulted in poor performance and lower concentration of blood metabolites but improved the nutrient digestibility and efficiency of lysine utilization. Compensatory growth response in terms of improved weight gain and feed efficiency was observed in pigs previously fed lysine-restricted diets during finisher 1, but the concentration of blood urea nitrogen and total protein were lower. No differences in growth performance, digestibility of nutrients and blood metabolites were noted during finisher 2. Lysine restriction of grower diets decreased the dressing percentage (quadratic, P 00.024), and protein content of longissimus muscle (linear P 00.034, and quadratic P 00.009). Thus, it could be concluded that pigs subjected to lysine restriction during grower phase exhibited compensatory growth responses in weight gain and improved efficiency of feed and lysine utilization for weight gain and lean accretion during finisher phase.

“…This is in agreement with similar rate of protein deposition in the muscle. It also confirms that compensatory growth is a complex phenomenon, and that other mechanisms also strongly contribute to compensatory protein deposition (Skiba 2005). Moreover, tendency to lower RNA concentration at 80 kg BW can indicate that transcriptional activity was reduced during the realimentation period.…”

The study was conducted to determine the changes in growth rate, protein deposition, concentration of nucleic acids, and activity of calpain enzymes in the longissimus dorsi muscle of pigs, which received a low protein and low energy diet from 25-50 kg bodyweight (BW) followed by adequate feeding to 105 kg BW in comparison with pigs fed adequately throughout the study. The muscle of pigs subjected to limitation tended to grow slower and deposit less protein daily (by 25%, p < 0.10), but have a significantly lower DNA concentration (by 13%, p < 0.01). The activity of micro- and m-calpain was also significantly lower compared with control pigs (0.942 vs. 1.92 and 0.246 vs. 0.403 U/g, respectively). After resumption of adequate feeding, the daily gain of muscle and protein deposition did not differ from control pigs. Moreover, at 80 kg and 105 kg BW the DNA and RNA concentration as well as the activity of m-calpain and micro-calpain did not differ between groups.

“…The response of animals varies according to the body weight at which feed restriction was started, the duration of restricted feeding and realimentation, and the extent to which feeding is restricted (SKIBA 2005, BEE et al 2006a, 2006b, DAZA et al 2006, HEYER and LEBRET 2007.…”

In an experiment with 56 pigs, the effects of feeding level and linseed oil supplement on fattening and slaughter parameters, the weight of internal organs, the concentration of hormones and indicators of protein and lipid metabolism, and the fatty acid profile of m. semimembranosus and backfat were investigated. During the growing period, all animals received a feed supplemented with 4 % linseed oil. At the end of the growing period (23-61 kg body weight), compared to semi-ad libitum fed animals, animals that were fed restrictively (25 % less feed) during this period were characterized by lower daily gains (P≤0.001), greater meatiness (P≤0.01), lower weight of internal organs, higher level of growth hormone (P≤0.05), lower levels of thyroid-stimulating hormone and blood urea nitrogen (P≤0.05), and dietetically more beneficial profile of fatty acids (more polyunsaturated fatty acids [PUFA]). During realimentation (61-104 kg body weight), when all animals were fed semi-ad libitum diets with 0 or 4 % linseed oil, daily feed intake and daily weight gains of the pigs that had previously been restrictively fed, were greater than in animals fed semi-ad libitum throughout fattening. Compensatory growth was found for the internal organs. Animals that received linseed oil diets throughout fattening were characterized during the finishing period by a higher rate of growth (P≤0.001), higher concentrations of triiodothyronine (T3) and insulin (P≤0.05), and a greater proportion of n-3 PUFA in the fatty acid profile of m. semimembranosus and backfat (P≤0.001).
