“…Quadratic effect (P<0.05) was observed on the variables nitrogen excreted in urine, nitrogen retention, percentage of nitrogen retained and percentage of retained/absorbed nitrogen, with greater retention and absorption of nitrogen until the level of 1.00% of digestible lysine; similar to the results found by Bolduan et al (1992) and Zangeronimo et al (2009), in the initial phase, and Oliveira (2006a) in the growth phase of pigs. According to Coma et al (1995), the highest rate of nitrogen retention represents greater protein deposition, and the highest lysine level results in efficient weight gain, i.e., lean meat.…”

“…The capacity to accumulate lean tissue in growing pigs is dependent on the fulfillment of the requirements of amino acids, especially lysine, considered the first limiting amino acid in most diets (Zangeronimo et al, 2009). Another important consideration about the protein deposition, determining the efficiency of utilization of dietary nutrients in the process of protein anabolism and pig growth is the corresponding intake of dietary energy.…”

-This study evaluated the relationship between digestible lysine and metabolizable energy for barrow and gilts from 24 to 50 kg. Performance, digestibility and blood profile were studied. The experimental design was of randomized blocks, with five treatments, eight replicates and two animals per experimental unit in the performance assay and four replicates and one animal per experimental unit in the digestibility assay. The blood profile was chosen at 20 random animals of each sex, with four replicates per treatment and the animal as experimental unit. The treatments were 0.80, 0.90, 1.00, 1.10 and 1.20% digestible lysine. There was a linear effect of lysine levels on weight gain and feed conversion in females and crude protein in both sexes, gross energy excreted in the urine (kcal) and digestible energy (kcal). A quadratic effect of the amino acid studied in the daily consumption of crude protein (g) in both sexes, weight gain and feed conversion of barrows, as well as the nitrogen excreted in the urine (g) and nitrogen retained, and absorbed and retained. The relationship between neutrophils and lymphocytes had quadratic responses with increasing levels of lysine. The maximum performance for the studied genotype was obtained with 0.88 and 0.91% of digestible lysine or 2.60 and 2.67 g of digestible lysine/Mcal of metabolizable energy for females and barrows, respectively, corrected for digestibility trial.

“…Carcass characteristics are very important in the pig industry, especially those related to a higher yield of meat and the smallest fat deposition, to meet the growing and demanding consumer market (Rosa et al, 2008;Zangeronimo et al, 2009). A larger quantity of carcass P meat of pigs has been the goal not only in the industry, because it improves profitability and decreases production costs.…”

The aim of this work was to evaluate the effects of different levels of metabolic energy (ME) in diets with a reduced level of crude protein (CP) on the performance and carcass characteristics of growing swine. Thirty-two high-performance barrows (initial weight of 22.5 ± 1.43 kg and final weight of 50.81 ± 2.54 kg) were distributed in a randomized block design with four treatments (three levels of ME - 3,060, 3,230 and 3,400 kcal/kg - in diets with 14% CP, and one control treatment with 3,230 kcal ME/kg and 18% CP) and four replicates. The diets were formulated with a true digestible basis of amino acids present in the feed, with methionine and threonine concentrations corrected as a function of lysine levels. The animals were slaughtered and their carcasses were studied. The ME levels did not affect the average weight gain, the feed:gain ratio, the backfat thickness or the loin eye area. A higher carcass yield and a higher carcass meat:fat ratio were observed in the animals that received the 3,230 and 3,060 kcal/kg ME levels. Compared to the control treatment, only the 3,400 kcal/kg ME level had a lower average daily feed intake. It is concluded that the CP level in diet should be reduced from 18% to 14% and the metabolizable energy level should be increased, thus reducing the feed intake and increasing the carcass meat:fat ratio without affecting the animal weight gain.
