Forty New Zealand White (NZW) rabbit does were equally divided among four groups feeding the same commercial diet and receiving a water solution containing, respectively, 0 (control), 100, 200 and 300 mg bee pollen/kg body weight (BW), 1 week before and after mating during moderate (October-February) and hot seasons (May-September) for three consecutive mating in each season. Does were mated with non-treated adult NZW male rabbits 11 days after kindling. Body weight of does, number of service per conception, conception rate, feed intake, litter size, milk production, blood constituents, weight of kits from birth up to weaning and survival rate were determined. For each season, 80 weaned rabbits originated from the does of the control group (untreated does) were equally divided into four groups (0, 100, 200 and 300 mg/kg BW) of bee pollen, given as a water solution twice per week from 4 to 12 weeks of age. The kit of the does given 100, 200 and 300 mg/kg BW did not receive bee pollen during the growing period (4-12 weeks of age). The effect of bee pollen on growing rabbit's performance was studied from 4 to 12 week of age. Bee pollen at 200 mg significantly (p < 0.01) increased body weight of does, conception rate, milk yield, litter size; improved biochemical profiles of blood and helps outstanding of does during both seasons. The same dose of bee pollen significantly increased kit growth and their survival rate until weaning. Growth and feed conversion ratio (FCR) of kits from the treated does during 4-8 weeks of age were significantly better than growth of kits from the untreated does that administrated bee pollen during 4-12 weeks of age. Meanwhile, during the following period (8-12 weeks of age) growth and FCR of kits given bee pollen from the untreated does were significantly better than that of treated does.
40 只新西兰白兔（NZW）被平均分为四组，在交配前一周和交配后一周内，分别给予相同的商业饮食和含有 0（对照组）、100、200 和 300mg 蜂花粉/千克体重（BW）的水溶液，在适度（10 月至 2 月）和炎热季节（5 月至 9 月）连续三个发情期内进行交配。发情期过后 11 天，母兔与未经处理的成年 NZW 公兔交配。测定母兔的体重、配种次数、受孕率、采食量、产仔数、产奶量、血液成分、断奶至断奶体重和成活率。每个季节，对照组（未处理的母兔）的 80 只断奶兔被平均分为四组（0、100、200 和 300mg/kg BW），每周两次给予蜂花粉水溶液，从 4 到 12 周龄。给予 100、200 和 300mg/kg BW 的母兔在生长期间（4-12 周龄）未接受蜂花粉。研究了蜂花粉对生长兔性能的影响，从 4 到 12 周龄。200mg 的蜂花粉显著（p<0.01）增加了母兔的体重、受孕率、产奶量、产仔数；改善了血液的生化特征，并有助于母兔在两个季节的表现。相同剂量的蜂花粉显著增加了断奶前的仔兔生长和成活率。处理母兔的仔兔在 4-8 周龄的生长和饲料转化率（FCR）明显优于未处理的母兔在 4-12 周龄给予蜂花粉的仔兔。同时，在接下来的时期（8-12 周龄），未处理的母兔给予蜂花粉的仔兔的生长和 FCR 明显优于处理母兔。
