Environmental impacts of 15 European pig farming systems were evaluated in the Union Q-PorkChains project using life cycle assessment. One conventional and two non-conventional from each five countries: Denmark, The Netherlands, Spain, France Germany. data needed for calculations obtained surveys 5 to 10 farms system. studied categorised into (C), adapted (AC), traditional (T) organic (O). Compared with C systems, AC differed little, only minor changes improve meat quality, animal welfare or...
Knowledge about the amino acid requirements and response of pigs to supply is essential in feed formulation. A deficient AA results a reduction performance while an oversupply costly leads excessive nitrogen excretion with potentially negative environmental impact. Amino are determined large extent by protein deposition body and, for lactating sows, exported milk. The concept ideal was developed more than 50 years ago refers profile that exactly meets animal's requirement so all acids...
Two groups of three multiparous Large White × Landrace sows were used to investigate the direct effect ambient temperature on mammary gland metabolism. Sows from first group exposed temperatures 28°C between d 8 and 14 lactation, 20°C 15 21; treatments reversed in second group. Four six after farrowing, an ultrasonic blood flow probe was implanted around right external pudic artery catheters fitted anterior vein carotid artery. After surgery all fed 3.8 kg/d a lactation diet. The...
This study was conducted to investigate the effects of feeding sows a bulky diet during gestation on their physiological and metabolic adaptations peripartum period, determine how these may relate sow piglet performances. From d 26 until farrowing, gilts were fed diets that contained 2.8 or 11.0% crude fiber (control high-fiber diets, respectively, n = 9/group). Daily feed allowance provided same amount DE daily (33 MJ DE/d). Throughout lactation, allowed consume standard lactating ad...
Residual feed intake (RFI) is defined as the difference between observed ADFI and predicted from production maintenance requirements. The objectives of this study were to evaluate RFI a selection criterion improve efficiency its potential reduce N P excretion in 4 pig breeds. Data collected 2000 2009 French central test stations for 2 dam breeds [French Landrace (LR) Large White (LWD)], sire [Large (LWS) Piétrain (PP)]. Numbers recorded pigs 6407, 10,694, 2342, 2448 LR, LWD, LWS, PP breeds,...
The incorporation of feed-use (FU) amino acids (AAs) in diets results a reduced use protein-rich ingredients such as soybean meal, recognized to have elevated contributions environmental impacts. This study investigated whether the L-lysine.HCl, L-threonine and FU-methionine reduces impacts pig broiler feeds using Life Cycle Assessment. following impact categories were considered: climate change, eutrophication, acidification, terrestrial ecotoxicity, cumulative energy demand land...
Twelve pregnant, multiparous sows were assigned during gestation to three dietary treatments in a 3 × Latin square design evaluate the effect of increasing levels crude fiber (CF): conventional diet low CF (L, 15.8 MJ DE/kg DM, 3.3% CF), with medium level (M, 14.4 10.6% and high-fiber (H, 12.9 18.1% CF). The daily feed supply was adjusted provide same 33.4 digestible energy (2.4, 2.7, 3.0 kg/d for diets L, M, H, respectively). Over day, shorter time standing spent when received H (291 min/d)...
Using 73 Large White gilts, we studied the lysine requirement during lactation. Sow and pig performance nitrogen balance of sows were measured total 21-d lactation period. Variation in body composition between farrowing weaning was determined by comparative slaughter technique. Two levels crude protein (15.5 17.1%) combined with two L-lysine HCl supplementation (0 .16%), resulting four diets termed P1L1, P1L2, P2L2, P2L3, containing .66, .77, .87% lysine, 15.5, 17.1, 17.1% protein,...
Abstract Between 45 and 100 kg body weight, Large White castrated males (cLW), crossbred Pietrain × fcPP×) boars (bPP×) were either given food ad libitum in experiment 1 or allocated to four energy levels (0·70, 0·80, 0·90, 1·00 ) 2. Daily protein amino acid supplies calculated be non-limiting for growth. Protein (PD) lipid (LD) deposition rates measured according the comparative slaughter technique over whole experimental period (experiments 2) nitrogen balance at stages of growth: 48, 64,...
A total of 120 crossbred [synthetic line x (Large White Landrace)] pigs (castrated males and females) were used to evaluate the influence rearing conditions for growing-finishing on growth performance, carcass, stress reactions at slaughter, meat eating quality. At approximately 35 kg live weight (LW), littermates allocated either a conventional (fully slatted floor, 0.65 m2/pig, considered as control, CON) or an alternative (sawdust bedding with free access outdoor area, 2.4 OUT) system,...
A model has been developed to predict pig manure evolution (mass, dry and organic matter, N, P, K, Cu Zn contents) related gaseous emissions (methane (CH4), nitrous oxide (N2O) ammonia (NH3)) from excreta up stored before spreading. This forms part of a more comprehensive including the prediction excretion. The simulates contrasted management systems, different options for housing (slatted floor or deep litter), outside storage treatment (anaerobic digestion, biological N removal processes,...
Considerable progress has been made in the nutritional modelling of growth. Most models typically predict (or analyse) response a single animal. However, to nutrients single, representative animal is likely be different from herd. To address variation between animals, stochastic approach towards required. In present study, an analysis method presented describe growth and feed intake curves individual pigs within population 192 pigs. This was developed allow end-users InraPorc (a model...
