ECOALIM: a dataset of the environmental impacts of feed ingredients used for animal production in France

Consulter le resumé

Aurélie Wilfart et al., 10es International Conference on Life Cycle Assessment of Food 2016, Dublin, Irlande du Nord, Royaume-Uni, 19-21 octobre 2016, 7 pages

Feeds contribute highly to the environmental impacts of livestock products. Therefore formulating low-impact feeds necessitates data of the environmental impacts of feed ingredients with consistent perimeters and methodology for life cycle assessment (LCA). We built the ECOALIM dataset of life cycle inventories (LCI) and associated impacts for feed ingredients utilised in animal production in France. It provides several perimeters for LCI (field gate, storage organization gate, plant gate and harbour gate) with homogeneous data source from R&D French institutes covering the period 2005-2012. The dataset of 149 environmental impacts is available as an Excel spreadsheet on the ECOALIM website and provides ILCD and CML climate change and acidification, eutrophication, CED non-renewable energy, phosphorus consumption, and CML land occupation. Life cycle inventories of the ECOALIM dataset are available in the Agribalyse® database in SimaPro® software. The ECOALIM dataset can be utilized by the feed manufacturer and the LCA practitioner to investigate the formulation of low-impact feeds. It also provides data for environmental evaluation of feeds and environmental evaluation of animal production systems.

Incidences des conditions d'élevage et d'alimentation en post-sevrage sur les performances en engraissement

ESP
Este estudio compara los resultados zootécnicos y las características de la canal de cerdos sometidos a diferentes tratamientos experimentales en la etapa de transición. Dichos tratamientos son el origen de una variación del peso vivo a la entrada en el engorde cuyo interés económico siempre es difícil precisar.
En este caso, se estudiaron los resultados de cuatro lotes de cerdos de engorde, y los tratamientos experimentales diferían en el manejo o la composición de aminoácidos de los piensos. Se compararon los rendimientos en el engorde según el tratamiento experimental recibido durante la transición.
Parece que las características nutricionales del pienso distribuido en transición tienen una incidencia limitada sobre la velocidad de crecimiento de los cerdos durante el periodo de engorde. Así, los resultados llevan a considerar que una desviación en el peso obtenido al final de la transición tenderá a permanecer en la misma proporción durante el cebo. Estos resultados abren la puerta a prácticas nutricionales menos intensivas en transición, dada la importancia de las patologías digestivas que se dan en esta etapa. Los cerdos más ligeros al inicio del engorde presentan a veces un nivel de consumo menor, unido a la reducción de sus necesidades de mantenimiento. Ante un descenso de la calidad de las condiciones de producción en la transición, los rendimientos de los animales en el engorde pueden verse afectados positiva o negativamente, lo que refleja la complejidad de la interacción entre el estatus sanitario y nutricional de los animales. Finalmente, en general, la incidencia de las condiciones de producción y las dietas empleadas en la transición sobre la calidad de las canales en el matadero parece ser limitada.

This study compare animal performances and carcass characteristics in pigs run through different post-weaning management regimes. The different treatments led to a tangible liveweight differential when transitioned to finishing. The study used four batches of finisher pigs. Post-weaning experiments focused on livestock management system or diet amino acid composition. Finisher performances were cross-compared according to post-weaning treatment. It appears that the nutritional properties of the feed distributed post-weaning have a limited impact on the pace of weight gain during finishing. The results suggest that any liveweight differential recorded at the end of the post-weaning period will tend to reproduce a same-degree differential at finishing. This findings open perspectives for de-intensifying diet practices in the post-weaning period, which is typically when pigs at this stage of growth are most vulnerable to digestive disorders. However, pigs that are lighter at early finishing sometimes present a lower feed conversion ratio due to their lower dietary maintenance needs. A slide in the quality of livestock management conditions in the post-weaning period can have either positive or negative impacts, which reflects the complexity of the interactions between health status and nutritional status. Post-weaning diet and farm management conditions ultimately appear to have only a limited impact on carcass quality at slaughter.

Eff ets de l’incorporation de pulpes de betteraves dans l’aliment d’engraissement

Consulter le resumé

Didier Gaudré, bilan 2017, éditions IFIP, mai 2018, p. 111

Du fait de la fin des quotas appliqués à la production de sucre, la culture de la betterave est appelée à se développer fortement et, avec elle, la disponibilité en coproduits de la betterave pour l’alimentation des animaux. En alimentation porcine, les pulpes de betteraves constituent le principal coproduit utilisé ; il est notamment incorporé dans les aliments pour truies et se rencontre aussi parfois dans les aliments pour porcelets. Cette matière première représente de fait une source d’énergie intéressante, tout en apportant aux truies des fibres très digestibles ; elle permet à cet égard de satisfaire les besoins en fibres des truies voire de maintenir un niveau suffisant de fibres dans les aliments de gestation et de lactation. Son utilisation dans les aliments pour porcelets est liée à sa capacité de participer au développement des segments distaux de l’intestin et de contribuer ainsi à la santé digestive des animaux au moment du sevrage.
Dans un contexte prévisible de disponibilités croissantes de cette matière première, l’étude a consisté à évaluer l’intérêt de l’incorporation de cette matière première dans les aliments pour porcs à l’engrais.

Effect of dietary fat or starch supply during gestation and/or lactation on the performance of sows, piglets’ survival and on the performance of progeny after weaning

Consulter le resumé

Two trials were carried out to compare the effects of fat or starch inclusion in sow’s diet on sow and litter performance. In each trial, sows were assigned to one of two treatments. In trial 1, the sows were fed diets containing either soybean oil (5%, treatment GL5) or cornstarch (11.3%, GL0) from day 35 of gestation to weaning. Daily net energy and nutrient allowance were equalised during gestation. In trial 2, the same treatments were applied only after farrowing (treatments L5 and L0, respectively). Within each trial, a batch of piglets was studied until slaughter.

Effect of diurnally fluctuating high temperatures on performance and feeding behaviour of multiparous lactating sows

Consulter le resumé

Forty-two multiparous Large White sows were used to investigate the effect of diurnally fluctuating temperature (T) on lactation performance and feeding behaviour. The animals were allocated to one of the four thermic treatments: constant T at 25°C (25C) and 29°C (29C) or equal-mean diurnal cyclic T varying from 21 to 29°C (25V) and from 25 to 33°C (29V). Photoperiod was fixed to 14 h of light. The sows were given food ad libitum between the 7th and the 19th day post partum. Lactation performance was measured for all sows whereas the feeding behaviour was recorded only on 28 sows.

Effect of feed presentation on growth performance of entire male pig and boar taint risk

Consulter le resumé

The aim of the trial was to compare the performance and boar taint risk when entire male pigs (40 per treatment) wrer fed xwith diets presented as mash (M) or ground pellets (G) over the 22-109 BW range. A liquid feeding system that allows for a simultaneous feeding was usd to control the daily feed allowance per pen (5 pigs/ pen) that corresponded to 4.5% of the initial BW per pen on the first dazy, thereafter + 25 g/d/pig up to 2.60 kg/d. Dietary nutrient contents were calculated from chemical characteristics of ingredients and coressponding nutritional values assessed fro mwww.evapig.com. The growing (<65 kg BW) and the finishing diets were formulated to contain 159 and 152 g/kg of crude protein, 9.2 and 8.2 g/kg of digstible lysine, 157 and 145 g/kg of total dietary fiber. The calculated net energy content was fixed at 9.64 MJ/kg. The daily feed intake tended to be lower with pellets (G : 195, M: 1.98 kg/d, P=0,06). As the average daily gain averaged 882 g/d (P=0.99), the feed conversion ratio was lower with pellets (G: 2,20, M: 2.26, P=0.05). No differences were noticed in carcass characteristics. Proportion of pigs with a low androstenone lever (<1 µg/g pure fat) averaged 96% for both groups. Less pigs presented a skatole level above the minimum detectable concentration (MDC, 30 ng/g) with pellets (G: 78, M: 97%, P=0.01) and their skatole concentration tended to be reduced (G: 64, M: 94 ng/g, P=0.07). When both skatole (S) and indol (I) levels were above MDC, the ratio S/I+S was significantly lower with pellets (G: 51, M: 61%, P=0.01), bu(t the coefficient of correlation betwwen S and S/I+S was similar for both treatments (r=0.78). The improved feed conversion ratio associated with a stable carcass composition at slaughter would result from an increased digestibility of nutrients induced by the technologies used in the pelleting process, which would contribute to reduce boar taint risk in entire male pigs.

Effect of feed restriction on the performance and behaviour of pigs immunologically castrated with Improvac®

Consulter le resumé

For centuries, entire male pigs have been castrated to reduce the risk of boar taint. However, physical castration of pig is increasingly being questioned with regard to animal welfare considerations. Immunization against gonadotrophin releasing hormone (GnRH) provides an alternative to physical castration. Using the currently available commercial product (Improvac®; Pfizer Animal Health), a two-dose regimen of a GnRH vaccine is administered.

Effect of parity and number of suckling piglets on milk production of sows

Consulter le resumé

Different factors are known to affect milk production in sows, especially sow parity and litter size (LS). In practice, milk production can be estimated from litter growth rate and LS. This approach is generally used for the determination of nutrient requirements. But information on factors affecting litter performance is scarce. Data from about 3 500 litters from three experimental units were used to quantify the effect of LS and parity on milk production estimated from piglet growth rate. On average, milk production reached 10.7 kg/day which is higher than most published results.

Effect of the dietary net energy concentration on feed intake and performance of growing-finishing pigs housed individually

Consulter le resumé

The effect of dietary NE content on feed intake and performance of pigs was investigated using crossbred barrows with initial and final BW of approximately 35 and 110 kg, respectively. Pigs were housed individually and allowed ad libitum access to feed. Pigs were randomly allotted to 6 wheat and soybean meal-based diets (8.1, 8.7, 9.3, 9.9, 10.5, and 11.1 MJ NE/kg) with 16 pigs/diet. Ratios between standardized ileal digestible AA and NE were similar in all diets.

Effects of a short exposure period to deoxynivalenol (DON) contaminated wheat on health parameters and post weaning and fattening performances of pigs

Consulter le resumé

Poster. The contamination of feed with the Fusarium toxin deoxynivalenol (DON) decreases feed intake and daily gain of pigs but also affects their immune response. An experiment was conducted to evaluate the effects of a brief contamination of post-weaning feed with DON on performance and health condition during post-weaning and fattening periods.

Effects of glucosinolates and fibre resulting from rapeseed meal inclusion in phase 2 diet on piglet feeding behaviour and performance

Consulter le resumé

Poster. Glucosinolates (GSL) and fibre from rapeseed may play a key role in the palatability of rapeseed meal (RSM) for pigs. Therefore, a high RSM inclusion in pig diets could lead to a lower feed intake or modify feeding behaviour, especially when competition is high. Two experiments were conducted to evaluate the eff ects of GSL and fi bre resulting from RSM, and of the competition degree at feeding, on feed intake and performance of piglets during the post-weaning period from 12 to 30 kg (phase 2).

Effects of increasing the farm produced content in organic feeds on pig performances

Consulter le resumé

In three experimental facilities (Exp.1, 2 and 3), two organic diets, one complex including processed feedstuffs as wheat bran and heat-treated soya beans (control), the other simplified and containing over 80% of cereal and pulses (CP), were compared for growing-finishing pigs. The base components of the CP diets were moist maize grain, wheat and faba beans in Exp.1, triticale plus coloured-flowered peas in Exp.2, and triticale, oats, white-flowered peas and faba beans in Exp.3. The control and CP diets were formulated with 0.75 g ileal digestible lysine per MJ NE.

visuel de Eric Royer et al., présenté aux 66e EAAP, Varsovie, Pologne, le 31 août-04 septembre 2015, session 14 : customized nutrition taking into account the health status of farms and individual animals, 11 pages

Four experiments were carried out to study the effect of dietary presentation on pigs. In a postweaning study, meal and pellets were compared in either good or bad sanitary conditions (Exp. 1, 14 pens/treatment). Over 41 days after weaning, pigs were offered ad libitum a phase 1 then a phase 2 diet in a dry feeder. The meal form increased DF1 (+6%, P<0.01) but reduced ADG (-4%, P<0.05), then increased FCR (+10%, P<0.01). Meal improved the faecal consistency at d 20 (+8%, P<0.05), but no differences were observed between treatments at d 5, 12 and 26. No interaction between presentation and sanitary conditions was found. In the fattening periods, diet was presented either as meal or ground pellets and delivered restrictively using a liquid feeding system to gilts and barrows (Exp. 2, 16 pens/treatment) or boars (Exp. 3, 8 pens/treatment). In Exp. 2 DFI averaged 2.13 kg for both presentations , but FCR (-5%, P<0.05), carcass yield (+1%, P<0.01) and carcass leanness (+0.4%, P=0.09) were (or tended to be) improved with pellets. In Exp. 3, the tendency for a lower DFI with pellets (-2%, P=0.06) without any difference in ADG resulted in a reduction in FCR (-3%, P=0.05). With pellets, fewer pigs presented a skatole level above the minimum detectable concentration in liquid fat (P=0.01). In Exp. 4 (32 pens/treatment), meal and pellets supplied in dry feeders and meal mixed with water in the trough were given to fatteners, either under restricted or ad libitum feeding conditions. The DFI was higher with liquid meal than with the other forms (P<0.01). During the growing phase, the highest ADG was found with pellets and the lowest with liquid meal, whereas during the finishing period ADG was higher with liquid meal and pellets than with dry meal. The FCR was 4 and 7% lower with pellets than with dry and wet meal, respectively (P<0.01). The improved FCR observed in Exp. 1 to 4 with pellets, compared with dry or wet meal, could be attributed to the increased digestibility of nutrients induced by technology used for diet preparation.

Effects of the trypsin inhibitor concentration in pig fattening diets on performance, health and carcass parameters

Consulter le resumé

Poster.

Protease inhibitors form complexes with trypsin and chymotrypsin, leading to a lower protein digestibility. However, pig tolerance for moderate dietary levels needs more assessment. Raw soybeans of three varieties (Baya, Isidor and Ecudor) differing in trypsin inhibitor content were substituted to extruded soybeans on a weight basis, to compare increasing concentrations of trypsin inhibitors in fattening diets averaging 0.8, 1.4, 2.1, 3.2 and 3.4 trypsin inhibitor units (TIU)/mg in Exp.1, and 0.8, 1.7, 2.1, 2.6, 4.4 and 5.3 TIU/mg in Exp.2. A total of 310 (LWxLd)xPP pigs (29.4 ±2.5 kg) were fed ad libitum up to 2.65 kg/d for females and 2.85 kg/d for barrows. No diarrhoea was observed and individual faecal scoring was similar among treatments. However, pen scoring showed a tendency for higher consistency in droppings with the 0.8 TIU diet at d 23 (P=0.08) and 30 (P=0.11) in Exp.1. During the growing period, feed intake was unaffected by treatments in Exp.1 but was decreased by 4.4 and 5.3 TIU diets in Exp.2 (P=0.03). Pigs offered 3.2 and 3.4 TIU/mg in Exp.1 had a decrease in daily gain by 11 and 13%, respectively (P=0.04), and an 8% increase in feed/gain (P<0.001). Similarly, 4.4 and 5.3 TIU diets affected daily gain (-15% and -9%, P=0.01) and feed/gain (+6% and +5%, P=0.02) in Exp.2. Nevertheless, performances were not significantly modified during the finishing period of both Exp.1 and Exp.2. Therefore, fattening pigs should not received more than 3.0 TIU/mg, although some compensatory mechanisms may occur over a length of time.
