Bridging Gaps in the Agricultural Phosphorus Cycle from an Animal Husbandry Perspective—The Case of Pigs and Poultry

Since phosphorus (P) is an essential element for life, its usage and application across agricultural production systems requires great attention. Monogastric species such as pigs and poultry can significantly contribute to global food security but these animals remain highly dependent on the supply of mineral inorganic P in their feeds. Pig and poultry, which represent 70% of the global meat production, are also major P excretors and thus represent important sources of environmental P inputs. Balancing the P cycle within farming systems is crucial to achieve P sustainable and resilient livestock production. Therefore, the interconnection of animal feed, livestock farming, manure, and soil/aquatic ecosystems requires multidisciplinary approaches to improve P management. With regard to a sustainable agricultural P cycle, this study addresses aspects of feeding strategies and animal physiology (e.g., phase feeding, P conditioning, liquid feeding, phytase supplementation, genetics), soil agroecosystems (e.g., P cycling, P losses, P gains), reuse and recycling (e.g., manure, slaughter waste), measures of farmers' economic performance (e.g., bio-economic models), and P governance/policy instruments (e.g., P quota, P tax). To reconcile the economic and ecological sustainability of animal husbandry, the strategic objective of future research will be to provide solutions for a sufficient supply of high-quality animal products from resource-efficient and economically competitive agro-systems which are valued by society and preserve soil and aquatic ecosystems.

“…Empirically, the aforementioned FI responses have a considerable literature support. While a decrease in FI, accompanied by reductions in the growth performance, was reported in piglets and growing-finishing pigs (79)(80)(81)(82) , other researchers found no changes in FI in the context of pigs of all stages of production (83)(84)(85) , broilers (86)(87)(88) and laying hens (89) . In laboratory animals, provision of P-deficient feeds was reported to lead to an increase in the overall FI (90,91) ; this could be an attempt to satisfy maintenance and growth requirements of the most limiting nutrient (63,92,93) , which would be consistent with FI responses in pigs given energy (94) and protein-deficient feeds (41,(95)(96)(97) .…”

Feeding strategies for growing monogastric livestock (particularly pigs) must focus on maximising animal performance, while attempting to reduce environmental P load. Achieving these goals requires a comprehensive understanding of how different P feeding strategies affect animal responses and an ability to predict P retention. Although along with Ca, P is the most researched macromineral in pig nutrition, knowledge gaps still exist in relation to: (1) the effects of P feed content on feed intake (FI); (2) the impact of P intake on body composition; (3) the distribution of absorbed P to pools within the body. Here, we address these knowledge gaps by gathering empirical evidence on the effects of P-deficient feeds and by developing a predictive, mechanistic model of P utilisation and retention incorporating this evidence. Based on our statistical analyses of published literature data, we found: (1) no change in FI response in pigs given lower P feed contents; (2) the body ash–protein relationship to be dependent upon feed composition, with the isometric relationship only holding for pigs given balanced feeds and (3) the priority to be given towards P retention in soft tissue over P retention in bones. Subsequent results of the mechanistic model of P retention indicated that a potential reduction in P feeding recommendations could be possible without compromising average daily gain; however, such a reduction would impact P deposition in bones. Our study enhances our current knowledge of P utilisation and by extension excretion and could contribute towards developing more accurate P feeding guidelines.

Perfil físico do fêmur de frangos de corte alimentados com níveis crescentes de quirera de soja. Physical profile of the femur of broilers fed with increasing levels of broken soybean. ________________________________________________________________________________ ResumoObjetivou-se avaliar o perfil físico do fêmur de frangos de corte alimentados com níveis crescentes (0, 3, 6, 9 e 12%) de quirera de soja crua nos períodos de sete, 14, 21 e 42 dias de vida. Foram utilizados 250 frangos de um dia de idade, machos, da linhagem Cobb®, o delineamento experimental inteiramente ao acaso, sendo cinco tratamentos com cinco repetições contendo 10 aves em cada. Houve efeito linear significativo dos níveis de inclusão da quirera de soja em todos os períodos avaliados. Conclui-se que a inclusão de níveis quirera de soja influência de forma negativa o fêmur de frangos de corte nos períodos de um a 42 dias. Palavras-chave: biometria óssea, coproduto da soja, osso AbstractThe objective of this study was to evaluate the physical profile of the broiler females fed with increasing levels (0, 3, 6, 9 and 12%) of raw soybean meal in the seven, 14, 21 and 42 days of life. A total of 250 one -day -old male broilers of the Cobb ® lineage were used, the experimental design being entirely random, with five treatments with five replicates containing 10 birds each. There was a significant linear effect of soybean inclusion levels in all evaluated periods. It was concluded that the inclusion of soybean yield levels negatively influences the broiler femur from one to 42 days.
