“…Currently, feed phosphate products mainly include dicalcium phosphate (DCP) [CaHPO 4 ·2H 2 O], monocalcium phosphate (MCP) [Ca(H 2 PO 4 )2·H 2 O], and mono-dicalcium phosphate (MDCP) [CaHPO 4 ·2H 2 O·Ca (H 2 PO 4 )2·H 2 O] [ 19 ]. DCP is the most widely used phosphate compound, but the phosphorus in DCP is barely soluble in water, and the absorption rate of its effective ingredients by poultry and swine is low (less than 60%) [ 20 ]. The remaining phosphorus and calcium elements are discharged in feces, causing pollution of groundwater resources, soil, etc.…”

Translucent egg consumption is low due to consumer acceptance and quality concerns, which is a problem that egg producers need to address. This study was performed to evaluate the reasons for the high occurrence of egg translucency in summer, as well as whether the addition of mono-dicalcium phosphate (MDCP) to the diet can relieve eggshell translucency and whether eggshell translucency is associated with the risk of bacterial invasion. A total of 72 laying hens that were 36 weeks old were randomly divided into control (CON) and MDCP groups and fed in the same environment. Results showed that the number of translucent eggs increases in July and August as the temperature and humidity increase. Compared with the CON group, in July, August, and October, the translucent egg grade (TEG) of the MDCP group was lower than that of the CON group (p < 0.05). TEG was correlated with mastoid space height (MSH), width (MSW), and area (MSA) (correlation coefficients 0.63, 0.59, and 0.68, respectively, p ≤ 0.05). There was no significant difference in the invasion rate of E. coli between translucent and non-translucent egg groups (47.2% vs. 39.33%), and translucent area and non-translucent area (13.49% vs. 15.08%). In conclusion, our results show that dietary MDCP may alleviate eggshell translucency and that eggshell translucency would not increase the probability of E. coli cross-shell penetration rate.

“…To achieve a 20% reduction in manure P content, taking account of the fact that over half of manure P comes from grass and silage consumption with an assumed P concentration of 0.33%, average supplementary animal feed P concentrations would have to drop to 0.25%. Given that minimum adequate dietary P levels in dairy cattle are around 0.35 to 0.42% ( Ferris et al., 2010 ), and opportunities to further reduce feed P in pigs and poultry beyond current phytase supplementation without welfare issues are limited ( Liu et al., 2019 ), such reductions in feed P content would not be sustainable. In 2005, the Northern Ireland Grain Trade Association entered into a voluntary agreement with the government to reduce the P content of animal feeds by 10% ( DAERA, 2019 ).…”

Current use and management of phosphorus (P) in our food systems is considered unsustainable and considerable improvements in the efficiency of P use are required to mitigate the environmental impact of poor P stewardship. The inherent low P use efficiency of food production from animals means food systems dominated by livestock agriculture can pose unique challenges for improving P management. This paper presents the results of a substance flow analysis for P in the Northern Ireland (NI) food system for the year 2017 as a case study for examining P stewardship in a livestock dominated agricultural system. Imported livestock feed was by far the largest flow of P into the NI food system in 2017 (11,700 t ± 1300 t) and P from livestock excreta the largest internal flow of P (20,400 ± 1900t). The P contained in livestock slurries and manures alone that were returned to agricultural land exceeded total crop and grass P requirement by 20% and were the largest contributor to an annual excess soil P accumulation of 8.5 ± 1.4 kg ha −1 . This current livestock driven P surplus also limits the opportunities for P circularity and reuse from other sectors within the food system, e.g. wastewater biosolids and products from food processing waste. Management of livestock P demand (livestock numbers, feed P content) or technological advancements that facilitate the processing and subsequent export of slurries and manures are therefore needed.

“…The result indicated that there was a massive animal manure production in HRB that was prone to pose a highly detrimental influence on water quality for HRB. Actually, the water quality in HRB was still a serious deteriorative status currently (Song et al, 2017;Xu et al, 2018;Liu et al, 2019;Yu et al, 2020). Based on the State of the Environment Report of China, 2.30 × 10 7 t COD and 2.40 × 10 6 t TN were discharged in 2013 (Lu et al, 2015).…”

“…The water quality from HRB has been observed worse than the Grade Ⅳ under the National Surface Water Quality Standards in China (Jiang et al, 2011), led to low drinking water security for approximately ten million local residents (Xu et al, 2018) as well as high cancer morbidity and mortality exceeding national average level (Lu et al, 2015;Han et al, 2016). The agricultural pollution, especially animal manure emissions, has outweighed municipal and industrial sources in HRB ( Zhang et al, 2015;Han et al, 2016;Liu et al, 2019 ). The intensive livestock and poultry farms have prevailed in HRB without an effective treatment pathway targeted at animal manure ( Zhou et al, 2013;Herrero et al, 2015;Hu et al, 2017;Song et al, 2018).…”

“…The intensive livestock and poultry farms have prevailed in HRB without an effective treatment pathway targeted at animal manure ( Zhou et al, 2013;Herrero et al, 2015;Hu et al, 2017;Song et al, 2018). Organic contaminants regarding to chemical oxygen demand (COD), biological oxygen demand (BOD), nitrate (NO 3 − -N), nitrite (NO 2 − -N) and ammonia (NH 4 + -N) and phosphorus (P) from the animal manure discharged into farmland directly, further affected water ecosystems through running off and leaching in HRB (Liu et al, 2019;Zhang et al, 2019). Relevant statistics showed that 2.10 × 10 6 t total nitrogen (TN) production from animal manure in HRB in 2015, approximately occupied 24.00% of the agricultural non-point sources (Song et al, 2017).…”

Effect and Risk Assessment of Animal Manure Pollution on Huaihe River Basin, China

Currently the deteriorated water quality for Huaihe River Basin (HRB) in China was still serious because of the negative influence multiple pollution sources including animal manure. However, little attention was paid to the potential risk of animal manure for farmland and water quality of HRB. This study was quantified and forecasted animal manure risk and its spatiotemporal variations in HRB from 2008 to 2018, through pollution discharge coefficient method and pollution load calculation, combined with kriging interpolation method of ArcGIS technology, based on statistics principle. All the data were originated from livestock and poultry breeding in HRB from 2008 to 2018. The future risk of farmland and water environment in HRB was further forecasted. The results indicated that the livestock and poultry manure has become a key pollution source causing a negative influence on farmland and water quality owing to a large amount of animal manure production without efficient recycle utilization. The chemical oxygen demand (COD) and total nitrogen (TN) discharge of animal manure in HRB almost accounted for 17.00% and 39.00% of the whole COD and TN discharge in China. The diffusion concentration of TN and TP in those regions of Shangqiu,
