PastureBase Ireland (PBI) is a web-based grassland management application incorporating dual function of decision support and centralized national database to collate commercial farm data. This facilitates the collection storage vast quantities data from farmers. The spans across ruminant enterprises – dairy, beef sheep. To help farmers determine appropriate actions around management, we have developed this informed tool at paddock level. Individual enter through completion regular pasture...
We compared two sorts of explanations for decisions made by an AI system: counterfactual about how outcome could have been different in the past, and prefactual it be future. examined effects these alternative explanation strategies on accuracy users' judgments app's predictions (inferred from information causes), to their diagnoses a cause outcome). The tasks were based simulated SmartAgriculture decision support system grass growth outcomes dairy farms Experiment 1, analogous alien planet...
Lameness in dairy cows is an area of concern from economic, environmental and animal welfare point view. While the potential risk factors associated with suboptimal mobility non-pasture-based systems are evident throughout literature, same information less abundant for pasture-based specifically those coupled seasonal calving, like Ireland. Therefore, objective this study was to determine specific scores (0 = good, 1 imperfect, 2 impaired, 3 severely impaired mobility) cows. Various cow...
Lameness in dairy cows can have significant effects on cow welfare, farm profitability, and the environment. To determine economic environmental consequences of lameness, we first need to quantify its effect performance. The objective this study, therefore, was associations various production reproductive performance measurements (including milk, fat, protein yield, somatic cell count, calving interval, death, or slaughter), mobility scores spring-calving, pasture-based cows. We collected (0...
Maximising herbage yield while reducing nitrogen (N) fertiliser input, particularly in spring, is essential to ensure environmental and economic sustainability on grassland farms. A plot experiment was conducted over 2 yr, comparing three different spring N application rates of 30 (30N), 60 (60N) 90 (90N) kg N/ha using strategies: 0:100 (S1), 50:50 (S2) or a 33:66 (S3) split across February March, respectively. Half the plots also received phosphorus (P) with first at rate 13 P/ha. Nitrogen...
To maximize efficiency, profitability, and societal acceptance of modern dairy production, it is important to minimize the production male calves with poor beef merit. One solution involves using sex-sorted sperm (SS) generate replacements breeding all other cows an easy-calving, short-gestation bull good We used Pasture Based Herd Dynamic Milk Model investigate effect herd fertility use SS on farm net profit in a 100 cows. This was completed by simulating herds differing performance (good,...
Moderate to severe forms of suboptimal mobility on dairy cows are associated with yield losses, whereas mild elevated somatic cell count and an increased risk be culled. Although the economic consequences (also referred as clinical lameness) have been studied extensively, generally ignored. Therefore, aim current study was determine varying prevalence within spring calving, pasture-based herds. A new submodel predicting scores developed integrated existing pastured-based herd dynamic model....
The herd dynamic milk (HDM) model is a capable of simulating the performance individual dairy animals (from birth to death), with daily time step. Within this study, HDM described and evaluated in relation production, body condition score (BCS) BCS change throughout lactation by comparing simulations against data from published experimental studies. model's response variation genetic potential, herbage allowance concentrate supplementation was tested sensitivity analysis.

Recently, Machine Learning (ML) has been heralded as a panacea for modelling problems across many domains, including Smart Agriculture (SmartAg), often in opposition to traditional mechanistic models arising on decades of scientific discovery. However, are successful "real world" problem-domains where ML encounter difficulties (e.g., the distribution test data is not same training data, violating so-called identical and independently distributed (i.i.d.) assumption). In this paper, we...
Abstract In pasture-based dairy production systems, identifying the appropriate stocking rate (SR; cows/ha) based on farm grass growth is a key strategic decision for driving overall business. This paper investigates number of scenarios examining effects SR (2–3 cows/ha (0.25 unit changes)), annual nitrogen (N) fertilizer application rates (0–300 kg N/ha (50 kg/ha soil type (heavy and free-draining soil) agroclimate location ((south northeast Ireland) across 16 years) pasture forage...
