“…On the other hand, to our knowledge, very limited data are available on comparison of N balance between pigs fed CSM and SBM diets until now. We found that CSM diets did not alter body protein deposition, SUN, Nd, and N efficiency in finishing gilts, even though daily N intake was slightly increased by 5.6 %, which is consistent with a previous study [ 32 ].…”

BackgroundThe current study was carried out to determine effects of dietary protein source and crude protein (CP) level on carcass characteristics, meat quality, and muscle amino acid (AA) profile in finishing gilts. The experiment was designed as a 2 × 2 factorial arrangement with two sources of dietary proteins (cottonseed meal, CSM vs. soybean meal, SBM) and two levels of CP (12 % vs. 14 %, as-fed basis). Seventy-two crossbred gilts (89.5 ± 0.9 kg) were allotted to one of four dietary treatments in a randomized complete block design for a period of 28 d. All diets were formulated to be isoenergetic and similar concentrations of standardized ileal digestible essential AA covering the nutrient requirements of pigs.ResultsGrowth, carcass characteristics and meat quality were not affected by dietary protein source nor crude protein level (P > 0.10) except that average daily feed intake was increased by CSM diets (P = 0.03). Gilts offered reduced protein diets had lower muscle pH45min (P < 0.05). Neither dietary protein source nor crude protein level influenced N deposition. However, reduced protein diets decreased N intake, N excretion, and serum urea nitrogen content, whilst improved N efficiency (P < 0.01). CSM diets increased N intake (P = 0.04), but did not depress N efficiency. The concentrations of phenylalanine, tryptophan, cysteine and tyrosine (P < 0.05) of the longissimus muscle were decreased when gilts offered CSM diets, while muscle intracellular free valine concentration was increased (P = 0.03). The gilts offered reduced protein diets had greater intracellular concentrations of free methionine, lysine, and total AA in muscle (P < 0.05).ConclusionThese results suggest that CSM could replace SBM as a primary protein source in finishing pig diets in terms of performance, N efficiency, carcass characteristics, and meat quality, but decrease the concentrations of muscle specific AA. Furthermore, the reduced protein diet played an important role in increasing muscle intracellular concentrations of specific free amino acids (FAA), and in reducing the relative ratios of specific FAA to lysine in longissimus dorsi muscle of pig, whose biological meaning needs further studies.Electronic supplementary materialThe online version of this article (doi:10.1186/s40104-015-0052-x) contains supplementary material, which is available to authorized users.

“…Our urine, feces and total nitrogen excretion values are similar to those found in the literature for the 20-40 kg [7], 40-50 kg [10] or 60-110 kg live weight categories [11]. In agreement with others, only small differences exist between the N-digestion of different genotypes and age categories [11,12].…”

Impacts of Age, Genotype and Feeding Low-Protein Diets on the N-Balance Parameters of Fattening Pigs

et al. 2022

The effects of feeding low-protein (LP) diets and the age and genotype of fattening pigs were evaluated in an N-balance trial. Sixty weaned piglets of two genotypes were allotted to three different diets. Besides the control diets for the crossbred Topigs 20 × DanBred Duroc (TD) and Hungarian Large White (HLW) pigs, two LP diets were fed containing 1.5 (T1.5) and 3% (T3) less dietary protein than the control. The LP diets were supplemented with crystalline lysine, threonine, tryptophan, and methionine to equalize their digestible amino acid contents. Starter diets were fed between 20–30, grower I between 30–40, grower II between 40–80 and finisher between 80–110 kg live weights. Pigs were kept in floor pens, with 10 animals per pen. In all phases, six pigs with similar live weight were placed into individual balance cages and in the frame of a seven-day long balance trial, the daily N-intake, fecal and urinary N-excretion were measured. From the data N-digestibility, the total ammoniacal nitrogen (TAN) and N-retention were calculated. All the investigated main factors, the genotype and age of pigs and the protein content of the diets had significant effects on the N-balance of fattening pigs. The determinacy of the factors depended on the investigated parameter. Fecal N-excretion and N-digestibility were steadier compared with the urinary N-exertion and TAN percentage. N-digestibility increased and the urinary N-excretion decreased when LP diets were fed. The urinary N-decreasing effect of LP diets was not linear. Compared with the control (19.6 gN/day), T1.5 treatment resulted in 14.5, treatment T3 in 12.4 g daily urinary N-excretion. The TAN and the N-retention of HLW pigs were more favorable than those of TD pigs. Based on our results, it can be concluded that the accuracy of the nitrogen and TAN excretion values of pigs, used in the calculation of the national NH3 inventories, could be improved if the genotype, the more detailed age categories and the different protein levels of feeds are considered.

“…For this purpose, producers make One of the nutritional alternatives investigated today is the use of cotton by-products, which, due to their relatively chemical composition and low cost, are a financially viable option for diet formulation. However, the presence of gossypol limits their use at high proportions, as gossypol can be toxic at high levels (Prawirodigdo et al, 1997).…”

The aim of the study was to evaluate the intestinal morphometry of broilers at 42 days of age fed diets containing different levels of cottonseed oil, with and without addition of ferrous sulfate. A total of 560 male Ross chickens were used in a completely randomized design with a 4×2 factorial arrangement and five replications with 14 birds. The cottonseed oil levels tested were 0%, 2%, 4%, and 6%. At 42 days of age, one bird per replicate was collected for morphometric. Analyzed variables were villus height, crypt length and muscle wall thickness. The statistical analysis was performed using SAS, P=0.05. In the duodenum and ileum, there was no significant effect of interaction between the treatments. In the jejunum, only the length of the crypt, the treatment with cottonseed oil 2%, more ferrous sulfate resulted in lower values; however, the same oil content without ferrous sulfate led to a greater length, which was also observed in the treatment with 4% oil plus ferrous sulfate. Inclusion of cottonseed oil in broiler diets at 42 days of age does not impair their intestinal morphology. Supplementation with ferrous sulfate at these levels is unnecessary, since no improvement was observed in the intestinal morphometric.
