The experiment was to clarify the effects of different numbers of squabs on feeding preferences of breeding pigeons during lactation. A total of 54 pairs 14-month-old similar performance breeding pigeons were randomly divided into 3 groups with 18 pairs per group. The breeding pigeons in the 3 groups nursed 2 (2+2 group), 3 (2+3 group) and 4 (2+4 group) squabs, respectively. During lactation period, breeding pigeons were fed a compound diet wtih the form of "mixed raw grains+compound pellet feed", and the compound diet contained 44.70% of compound pellet feed, 20.70% of corn, 15.70% of pea, 10.50% of sorghum and 8.40% of wheat. Record the type and weight of surplus feed daily and the feeding period was 21 days. The results showed as follows:1) the actual feeding proportions of 4 raw grains of breeding pigeons in the 3 groups were higher than their proportions in the compound diet, while the actual feeding proportion of compound pellet feed was lower than its proportion in the compound diet. The feeding proportion of corn was 26.52% in the 2+2 group, which was extremely significantly higher than that in the 2+3 and 2+4 groups (P<0.01); the feeding proportion of pea was 20.12% in the 2+4 group, which was extremely significantly higher than that in the 2+3 and 2+2 groups (P<0.01); the feeding proportion of wheat was 11.14% in the 2+4 group, which was extremely significantly higher than that in the 2+3 and 2+2 groups (P<0.01); the feeding proportion of compound pellet feed was 35.35% in the 2+3 group, which was significantly higher than that in the 2+2 and 2+4 groups (P<0.05). 2) The actual intakes of crude protein (CP), ether extract (EE), calcium (Ca) and total phosphorus (TP) of breeding pigeons in the 3 groups were lower than the corresponding nutrient content in compound diet, while the actual intake of metabolic energy (ME) was higher than the ME in compound diet. The intake of CP was 13.93% in the 2+2 group, which was extremely significantly lower than that in the 2+3 and 2+4 groups (P<0.01); the intake of EE in the 2+4 group was extremely significantly lower than that in the 2+2 and 2+3 groups (P<0.01); the intakes of Ca and TP in the 2+3 group were significantly higher than those in the 2+2 group (P<0.05), and there was not significantly different from the 2+4 group (P>0.05); there was no significant difference in the intake of ME among the groups (P>0.05). In conclusion, compared with the compound pellet feed, breeding pigeons prefer raw grains during lactation period. As the numbers of squabs increasing, breeding pigeons will reduce the intake of energy feed corn and increase the intake of protein rich pea.
