This study aims at investigating the productive performance, metabolic, and hematological profiles of Algerian local rabbits does during their first pregnancy and according to dietary protein content.
A total of 52 nulliparous rabbit does, 3,116 ± 72.9 g live weight, were allocated individually to three groups (17/18 females per group) being on isoenergetic diets [2,600 kcal Digestible Energy (DE)/kg] that differ in their digestible protein content by 15%, 17%, and 19%, respectively, for L, M, and H diets. All these diets were provided .
The use of a high protein diet did not affect does weight and feed intake during the pregnancy period. Statistically, no significant difference ( > 0.05) was recorded in born or alive litter size and birth weight. There was no effect of diet and sampling time ( > 0.05) on plasma metabolites but there were significant effects of sampling time ( < 0.0001) on the metabolic parameters studied with prolificacy used as a covariate. Hematologic indices in pregnant rabbits were not affected by the diet exceeded the red blood cells rate that increased significantly ( < 0.05) with the increase in dietary protein content during the different periods of gestation.
The use of a high protein diet has no effect on weight during the pregnancy period. No effect of diet and sampling time on plasma metabolites and hematological profiles are recorded; however, significant effects of sampling time are recorded on the metabolic parameters.
本研究旨在调查阿尔及利亚本地母兔首次怀孕期间的生产性能、代谢和血液学特征，并根据日粮蛋白质含量进行分析。
总共52只未产过仔的母兔，活重3116±72.9克，分别被单独分配到三组（每组17/18只雌性），饲喂等能量日粮[2600千卡可消化能量（DE）/千克]，其可消化蛋白质含量分别为15%、17%和19%，分别对应低、中、高蛋白质日粮。所有这些日粮均已提供。
在怀孕期间，使用高蛋白日粮对母兔体重和采食量没有影响。从统计学角度来看，出生或存活的窝仔数和出生体重没有显著差异（P>0.05）。日粮和采样时间对血浆代谢物没有影响（P>0.05），但采样时间对以繁殖力作为协变量研究的代谢参数有显著影响（P<0.0001）。怀孕母兔的血液学指标不受日粮影响，但红细胞率除外，在妊娠不同阶段，红细胞率随日粮蛋白质含量的增加而显著升高（P<0.05）。
在怀孕期间，使用高蛋白日粮对体重没有影响。日粮和采样时间对血浆代谢物和血液学特征没有影响；然而，采样时间对代谢参数有显著影响。
