Composition of the Non-Protein Nitrogen fraction of goat whole milk powder and goat milk-based infant and follow-on formulae
International Journal of Food Sciences and Nutrition, 2008Co-Authors: Colin G. Prosser, R.d. Mclaren, D.a. Frost, M.p. Agnew, Dianne LowryAbstract:The Non-Protein Nitrogen fraction of goat whole milk powder and of infant and follow-on formulae made from goat milk was characterized and compared with cow milk powder and formulae. Goat milk infant formula contained 10% Non-Protein Nitrogen, expressed as a proportion of total Nitrogen, compared with 7.1% for cow milk formula. Goat follow-on formula contained 9.3% and cow 7.4% Non-Protein Nitrogen. Urea, at 30%, was quantitatively the most abundant component of the Non-Protein Nitrogen fraction of goat milk and formulae, followed by free amino acids at 7%. Taurine, glycine and glutamic acid were the most abundant free amino acids in goat milk powders. Goat milk infant formula contained 4 mg/100 ml total nucleotide monophosphates, all derived from the goat milk itself. Goat milk has a very different profile of the Non-Protein Nitrogen fraction to cow milk, with several constituents such as nucleotides at concentrations approaching those in human breast milk.

Nitrogenous components of human milk: Non-Protein Nitrogen, true protein and free amino acids
Food Chemistry, 2003Co-Authors: Brunella Carratù, C. Boniglia, Francesco Scalise, Amalia Maria Ambruzzi, Elisabetta SanziniAbstract:Abstract This study reports the Nitrogen distribution as total Nitrogen, protein Nitrogen, Non-Protein Nitrogen and free amino acids in milk, from 195 healthy nursing mothers, of 1 month of lactation. The purpose was to provide data on mature breast milk with the aim of increasing the knowledge of the physiological and nutritional role of human milk. Human milk samples were collected on the 30th day of lactation from well-nourished mothers of term infants in seven pediatric centres in northern, central and southern Italy. The protein and total Nitrogen levels were 12.6 g/l±2.0 and 2350 mg/l±390 respectively. The percentage of non protein Nitrogen was 15% and the absolute value was 341 mg/l±76. The amount of Nitrogen derived from each amino acid varied widely; the cumulative amino acid Nitrogen presented a minimum of 13 mg/l and a maximum of 82 mg/l. Taurine, serine, glutamic acid and glutamine were the only free amino acids, accounting for a large proportion of the FAA in the Non-Protein Nitrogen fraction. The sum of glutamic acid and glutamine (1430 μmol/l±489) in human milk samples represented 49% of total free amino acids.

Effects of different compound Non-Protein Nitrogen feed on the performance of milking goats
1997Co-Authors: Zhiyun Wang, Tiefeng SongAbstract:Three different compound Non-Protein Nitrogen feeds (A,B and C) were tested in this study. The contents of iron, copper, cobalt, iodine, Zinc and chilli powder were different in A,B and C, while the contents of other nutrients were the same. The milk yield, feed efficiency and net income of feed B were increased 10.82% (P

Research on influence of different Non-Protein Nitrogen (NPN) compounds in beef cattle feeding
Journal of Central European Agriculture, 2019Co-Authors: Zvonimir Steiner, Ivana Klarić, Josip Novoselec, Željka Klir, Boris Antunović, Ivan Babić, Mario RontaAbstract:The aim of the study was to investigate the activity of slow-release Non-Protein Nitrogen compound with the enzymatic activity (SENPN) and to compare it with the activity of slow-releasing Non-Protein Nitrogen compound (SNPN) in beef cattle feeding. The following indicators were monitored: body weight (BW), average weight gain (AWG), feed conversion ratio (FCR), trunk weight at slaughter (TWS) and dressing percentage (DP). Beef cattle were divided into two groups of uniform body weights ; control group (CG) and experimental group (EG). The feed ration of the CG contained SNPN, while the feed ration of the EG contained SENPN. During the trial, three weights were performed to measure BW. The trial consisted of two parts: (i) the first part of the trial refers to the period between the first and second weighing, in which the feed ration of the EG contained 4.81% less starch per kg of dry matter (DM) compared to the feed ration of the CG, and (ii) the second part of the trial was conducted in the period between the second and third weighing, in which the feed ration contained equal starch levels. After the third weighing, the beef cattle were transported to the slaughterhouse, where they were sacrificed, and subsequently the values of TWS and DP were measured. There were no statistically significant differences found for each of the measured parameters. In conclusion, the usage of SENPN positively affects the utilisation of nutrients in the mixture, e.g. feed ration.
