“…A second reason is to provide a safety factor in diet formulation to assure that P requirements are met. A review paper reported that surveys in the United States in the 1990 s found that diet P levels were often 25% above requirements [72].…”

The dairy industry is under pressure to reduce its environmental impact while producing more milk to meet society’s needs. Precision feed management (PFM) is one tool that can be used to meet this challenge. A simple definition of PFM is to provide adequate, but not excessive, nutrients to meet animal requirements. There has been an industry trend to decrease diet nitrogen (N) and phosphorus (P) in the last 20 years. New York herds lowered diet N by 10.8% between 1999 and 2019. Milk per cow increased by 40% during this time, while total manure N excretion decreased by 8.1%. Research results from on-farm trials have consistently indicated that lowering diet crude protein (CP) decreases manure N excretion while improving profitability; in a 3-year study with 8 herds, diet CP was decreased by 9.7%, while manure N excretion was 14% lower. Income over purchased feed cost increased by $137/cow/year. Carbon footprint (CF) has also decreased. A decrease of 19% between 2007 and 2017 was reported for the United States dairy industry. The dairy industry has already made significant strides in improving milk production while lowering its impact on the environment; however, there are additional opportunities to further reduce nutrient excretion and emissions into the environment and increase the efficiency of nutrient use.

“…Caballero et al, (1996) determined the Mn content of common vetch as 50.3 ppm. Phosphorus (P), a required nutrient for all livestock, has numerous essential physiological functions in the body that include energy transfer (ATP), structure of bone, teeth, and membranes, and buffering pH changes in the rumen (Satter et al, 2005). Phosphorus content of common vetch accessions varied between 0.84 and 3.65 % (Table 5).…”

The objective of this study was to determine chemical composition of 24 common vetch (Vicia sativa L.) accessions, collected from natural flora in European part of Turkey. The field experiment was carried out in the 2015-2016 growing season at field experimental area of Tekirdag Namık Kemal University, Agricultural Faculty, Field Crops Department in Tekirdag/Turkey. In this study, chemical structure (nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), copper (Cu), zinc (Zn), iron (Fe), and manganese (Mn) content) of common vetch accessions were determined on hay. Chemical composition content were statistically significantly different (P≤0.01) between accessions. According to the results obtained from field experiments, N, P, K, Ca, Mg, Cu, Zn, Fe, and Mn content of common vetch accessions varied between 0.95–3.14 %, 0.84–3.65 %, 0.22–2.44 %, 0.89–2.85 %, 0.23–0.74 %, 0.15–7.80 ppm, 0.10–5.30 ppm, 43.00–2295.20 ppm, 3.08–17.50 ppm, respectively. A wide variation was observed among common vetch accessions used in the study for N, P, K, Ca, Mg, Cu, Zn, Fe, and Mn content. Tetany and Ca/P rates of accessions changed from 0.13 - 1.54 and 0.28 - 2.19, respectively. The tetany and Ca/P rates of common vetch accessions are within suitable values for animal feeding. Ca/P ratio is above the limit value only in accessions 15-2 and 14O04. According to the correlation analysis, N was positively and significantly correlated with P, K, Mg, Cu and Fe. Similarly, P was positively and significantly correlated with N, K and Fe. Magnesium was positively and significantly correlated with N, Ca, Cu, Fe and Mn. Iron was positively and significantly correlated with N, P, Ca, Mg and Cu. As a result, accession 15K17 and 33 were identified as common vetch accessions with high mineral nutrition content.

“…Phosphorus (P) performs several functions in animals that are related to the transfer of energy, composition of bones, teeth, cell membranes and nucleic acids. It is also considered a growth factor for the ruminal microbiota, participating in the control of ruminal pH and acid-base balance (Breves & Schroder 1991, Underwood & Suttle 1999, Satter et al 2005.…”

Evaluation of phosphorus levels in bones and serum of buffaloes (Bubalus bubalis) before and after supplementation with a selective mineral mixture

et al. 2023

This study aimed to evaluate phosphorus (P) concentration in serum and bone, the percentage of ash and the specific bone density of buffaloes on Ilha de Marajó before and after mineral supplementation. For this study, 14 crossbred buffaloes of Murrah and Mediterranean descent aged between 18 and 36 months were used. The average values of P before supplementation in serum and bone, the percentage of bone ash and the specific bone density were 5.68mg/dL±1.18, 16.53%±0.53, 59.95%±1.96 and 1.52g/cm3±0.32, respectively, which demonstrated P deficiency in animals raised on Ilha de Marajó. After supplementation with P for a period of seven months, the values were 6.61mg/dL±0.87, 16.90%±0.56 and 60.30%±0.95 and 1.71g/cm3±0.21, respectively. These results showed a significant increase in P concentration in blood serum, specific bone density and percentage of P in ash (P<0.05), but there was no significant increase in the percentage of ash. The average increase in P in the serum and ash did not reach normal levels in all animals; however, 28.6% of the animals had normal values of P in serum and 50% in the ash, and 64.3% had normal specific bone density values. The nonre-establishment, in some of the animals, of the variables of P serum and bone after supplementation for seven months may have occurred as a result of the low intake of the mineral mixture and by the low concentration of P in the Brachiaria brizantha cv. Marandu used for feeding animals during the experiment.
