“…Other behavioural studies carried out with the same pigs indicated that the behaviour of Nn and NN may differ when subjected to a novel stimuli, but was quite similar in a social context (E. Fàbrega et al, 2001, unpublished results). Feeding behaviour has been said to differ considerably when pigs are housed in groups as opposed to individually (de Haer and Merks, 1992;Bornett et al, 2000) due to social facilitation, competition or group cohesion. Our results indicate that social influences surpass the effect of halothane genotype in heterozygous pigs, and further research would be required to determine whether differences in feeding patterns between NN and Nn pigs occur when animals are kept individually.…”

“…Overall, it seems that there is a general agreement with the fact that terminal sire line does have an effect on feeding patterns (de Haers and de Vries, 1993;Labroue et al, 1994 and1999;Quiniou et al, 1999;Augspurger et al, 2002) but its influence may be mediated through other factors such as social context. If flexibility of feeding behaviour is assumed (Nielsen, 1999;Bornett et al, 2000), then there may be certain feeding patterns (such as daily food intake) that are more consistent and easier to define for each breed, while other parameters (such as feeding rate) are more flexible, being a response to social or environmental challenges.…”

The effects of terminal sire line, halothane genotype and age on feeding patterns and growth performance were studied in 208 castrated growing-finishing pigs distributed in two batches. In batch 1 (no. = 130), pigs came from crosses of NN Landrace × Large White sows with a Pietrain Nn (Pi-Nn) or a Large White ✕ Pietrain Nn terminal sire line (LwPi-Nn). In batch 2 (no. = 78), the same sows were used but crossed with three different terminal sire lines : a Pietrain nn (Pi-nn), and two Pietrain NN (Pi-NNa and Pi-NNb). Growth performance and feeding patterns of the progeny (Nn or NN for the halothane gene) were measured from 67 to 166 days of age. Pigs were housed in groups of 10 and 13 individuals in Batch 1 and 2, respectively, with a random mixed-breed and halothane genotype sample in each group (space allowance 1·3 m 2 per pig and 1·1 m 2 per pig, respectively). Feeding patterns were monitored with a computerized food intake recording system (IVOG ® -station) and every 3 weeks pigs were weighed and backfat and loin-muscle depth were ultrasonically recorded (PIGLOG ® ). Carcass quality was assessed with the Fat-o-Meater grading probe. In batch 1, halothane genotype did not have a significant effect on any of the feeding patterns recorded, but Nn individuals had a significantly higher body weight ( P < 0·05), loin-muscle depth ( P < 0·05) and lower backfat thickness ( P < 0·01) in the last measurement taken, 3/4 carcass loin depth ( P < 0·05) and lower carcass last rib backfat ( P < 0·05) than NN pigs. Terminal sire line had a significant effect on all feeding patterns recorded except for feeding rate, Pi-Nn sired pigs showing a significantly higher food intake per visit ( P < 0·05) and feeder occupation time per visit ( P < 0·05) and lower number of visits ( P < 0·001) compared with LwPi-Nn sired pigs which, in turn, showed significantly higher food intake per day ( P < 0·001) and feeder occupation time per day ( P < 0·01). Terminal sire also affected growth performance and body composition, Pi-Nn sired pigs having a significantly lower body weight ( P < 0·001) and backfat thickness ( P < 0·001) but higher killingout proportion and 3/4 loin depth ( P < 0·01) than LwPi-Nn sired pigs. In batch 2, Pi-NNb sired pigs showed a significantly lower food intake per day compared with the progeny of the other two terminal sires lines at some of the age measurements taken ( P < 0·05). The rest of the feeding patterns was not affected by terminal sire line. Body and carcass weights were also significantly lower ( P < 0·01) for Pi-NNb sired pigs, but their killing-out proportion was higher than Pi-NNa sired pigs. With regard to these variables, Pi-nn sired pigs held an intermediate position between the two NN terminal sire lines. In both batches, age was associated with a significant increase in food intake per visit and per day and feeding rate ( P < 0·001) and a decrease in feeder occupation time per visit and per day and frequency of visits to the feeder ( P < 0·001). Overall, the present results suggest differences between...

“…Differences in ADFI are demonstrated to be associated with important differences in feeding behaviors. Regardless of the feeder design, when feeding spaces do not seem to be limiting, growing-fi nishing pigs in groups fed for ad libitum intake have demonstrated a diurnal pattern of feeding similar to that observed for individually housed pigs (de Haer and Merks, 1992;Nielsen et al, 1995a;Bornett et al, 2000). Others also have reported that 2 peak periods of feeding activity may occur during the day, a morning period and an afternoon period (Walker, 1991;de Haer and Merks, 1992;Nielsen et al, 1995a).…”

Our objectives were to compare a conventional dry (5-space, 152.4-cm-wide) and a wet-dry (double-sided, each side = 38.1-cm-wide single space) feeder and to determine if changing the source of water to a location separate from a wet-dry feeder would result in improved G:F and carcass characteristics. Water supply to the wet-dry feeder was shut off and the cup waterer was turned on in 8 pens at 8 (d 69) or 4 (d 97) wk prior to harvest. For the remaining 8 wet-dry feeder pens, the feeder provided the sole water source for the entire experiment. A total of 1,296 pigs (PIC, 337 × 1050; initially 19.4 kg BW) were used, with 27 pigs/pen (14 barrows and 13 gilts) and 24 pens/feeder design. From d 0 to 69, pigs fed with the wet-dry feeder had increased (P < 0.05) ADG, ADFI, G:F, and d 69 BW compared with those using the conventional dry feeder. Overall (d 0 to 124), pigs using fed with the water source in the wet-dry feeder the entire time had greater (P < 0.05) ADG, ADFI, final BW, and HCW the other treatments. The overall G:F was not different (P > 0.05) among pigs fed with the different feeder treatments. Pigs fed with the wet-dry feeder where water source was changed at 4 wk before harvest had greater (P < 0.05) ADG than pigs that used a conventional dry feeder. Pigs where the water source was changed at 4 wk had greater (P < 0.05) ADFI than those were the water source was changed 8 wk prior to harvest, and for pigs fed with the conventional dry feeder ADFI was intermediate. Back fat depth of pigs where the water source was changed at 8 wk before harvest was reduced (P < 0.05) compared with all other treatments and LM depth was greater (P < 0.05) than that of pigs using a conventional dry feeder and where the water source was changed at 4 week before harvest. Pigs fed using the wet-dry feeder visited the feeder less frequently (P < 0.05) and spent less total time at the feeder (P < 0.05) than those fed with the conventional dry feeder. The differences in feeding patterns remained even after the access to water was removed from the wet-dry feeder, with no change in the amount of aggressive behavior observed at the feeder. Pigs fed with a wet-dry feeder had an increased growth rate compared with those fed with a conventional dry feeder. Although measures of carcass leanness were improved by changing the location of the water, removing the water from the feeder also eliminated any net improvement in BW from using a wet-dry feeder.

“…A verekedések száma a csoportban lévő egyedek számával arányosan nő (MORRISON et al 2007). A nagyobb sűrűség pedig hatással van a testtömeg alakulására, illetve a reprodukciós paraméterekre is (BORNETT et al 2000, TURNER et al 2000. A TUR- NER et al (2001) által végzett vizsgálatokból is látszik, hogy már néhány egyeddel való eltérés is jelentősen befolyásolhatja az agresszió mértékét.…”

Összefoglalás.A vaddisznó a vadgazdálkodás számára jelentős bevételt jelent, szabadterületen állo-mánya folyamatosan nő; a vaddisznós kerti vadászat iránti igényeket mégis egyre nehezebb teljesíte-ni, habár a kertben lévő állományok nagy része befogásból származik. Ahhoz, hogy a pár napos vadá-szat során a kertet üzemeltetők biztosítani tudják a vendégek által "elvárt" nagy terítékű vadászatokat, nagy létszámban kell tartaniuk a vaddisznókat. Ez pedig sokszor nagy állománysűrűséggel is párosul, aminek oka a kis, általában 200 és 500 hektár közötti kiterjedésű terület. Zárt tartásban, legyen az vadászati célú kert, vagy hústermelést szolgáló farm, a speciális életkörülmények miatt az egyedek viselkedése meg fog változni a szabadterületi társaikhoz képest. A vizsgálat során szabadterületi és kerti állományok, kondák viselkedésbeli különbségeit vizsgáltuk egy táplálék-kompetíciós helyzetben, rá-világítva így azokra a lehetséges okokra, amelyek miatt a kertek többsége nem önfenntartó, az ottani szaporulat jelentős része elhullik. Az eredményeink alapján elmondható, hogy a vaddisznóskertben megnőtt az egyedek szociális interakciókkal töltött ideje, míg a táplálkozásra fordított idejük pedig jelentősen kevesebb volt. A kerti kocákat tekintve, jelentősen megnőtt agressziót figyelhettünk meg. Összességében elmondható, hogy a nagyobb állománysűrűség okozta stressz a malacokra volt jelentős hatással, mely negatív hatások azonban eddigi vizsgálataink eredményei és javaslataink alapján csökkenthetőek lennének.Kulcsszavak: szociális viselkedés, táplálék kompetíció, állatjólét, agresszió, vaddisznós kert. BevezetésA társas életet élő állatok körében a csoporton belül a fajra jellemző szociális rendnek kell kialakulnia, különben a közösség a legrövidebb időn belül felbomlana (MEYNHARDT 1986). A hierarchia a csoportban előre meghatározza az egyedek számára a források hasznosíthatóságát (HAGELSÖ GIERSING & STUDNITZ 1996) a rangsorban elfoglalt helyükhöz kötődő viselkedéselemek által (például fenyegetés, behódolás, elkerülés). Egy zárt kertben azonban a források végesek, ami pedig növeli az egyedek közötti kompetíciót (táplálék -a helytelen takarmányozásnak és nagy állománysűrűségnek köszönhetően a terület eltartóképessége folyamatosan csökken; búvóhely stb.), ez pedig szociális stresszt, agreszsziót válthat ki (HUGHES et al. 1997;MCGLONE 1985). Egy zárt helyen, ahol rangsoron kí-vüli, egymásnak idegen egyedeket társítanak, azok a hierarchia hiányában addig fognak 65
