The aim of this thesis was to evaluate the effects of diet (fibre diet vs. starch diet), age at first mating (19 vs. 21 weeks), litter size (standardized to 10 or 11 kits), and group size (does housed individually or in pairs) on the reproductive performance of young rabbit does and the growth of their kits. In particular, group housing (applied before kindling) and diet (administered until 5 days before kindling) were considered as residual effects. From 23 days of lactation until weaning, the two experimental diets were reintroduced. To this end, 144 nulliparous does (Grimaud) were assigned to 16 experimental groups, resulting from the factorial combination of the following factors: diet (F vs. S), age at first mating (E vs. L), litter size (N10 vs. N11), and group size (1 vs. 2).
La presente tesi ha avuto l’obiettivo di valutare l’effetto della dieta (una più fibrosa e una più amilacea), dell’età al primo accoppiamento (19 vs. 21 settimane), della numerosità della nidiata (pareggiata a 10 o 11 coniglietti) e della numerosità del gruppo (allevamento individuale o in coppia delle fattrici) sulle prestazioni riproduttive di giovani coniglie e sull’accrescimento dei coniglietti. In particolare, l’allevamento in coppia, effettuato prima del parto, e la dieta, somministrata fino a 5 giorni prima del parto, sono stati considerati come effetti residui. A partire da 23 giorni di lattazione, i due mangimi sperimentali sono stati nuovamente somministrati fino allo svezzamento. A tal fine, 144 coniglie nullipare (Grimaud) sono state suddivise in 16 gruppi sperimentali, risultanti dalla combinazione fattoriale dei seguenti fattori: dieta (F vs. S), età al primo accoppiamento (E vs. L), numerosità della nidiata (N10 vs. N11) e numerosità del gruppo (1 vs. 2).

Abstract
The aim of this thesis was to evaluate the effects of diet (fibre diet vs. starch diet), age at first mating (19 vs. 21 weeks), litter size (standardized to 10 or 11 kits), and group size (does housed individually or in pairs) on the reproductive performance of young rabbit does and the growth of their kits. In particular, group housing (applied before kindling) and diet (administered until 5 days before kindling) were considered as residual effects. From 23 days of lactation until weaning, the two experimental diets were reintroduced. To this end, 144 nulliparous does (Grimaud) were assigned to 16 experimental groups, resulting from the factorial combination of the following factors: diet (F vs. S), age at first mating (E vs. L), litter size (N10 vs. N11), and group size (1 vs. 2).| File | Dimensione | Formato | |
