Dietary effects of the inclusion of white lupine seeds and different types of binders on the blood indicators of young Dwarf Lop rabbits

Abstract

The aim of the present study was to evaluate the effects of the inclusion of whole seeds of white lupine and different binder types in complete pelleted diets on selected haematological and plasma biochemical indicators of growing dwarf rabbits. The individual litters of Dwarf Lop rabbit kits were randomised after birth into control (n = 12) and experimental (E) groups. The young rabbits of the E group (n = 24) received an experimental pre-weaning diet containing a 25% share of white lupine seeds. At the time of weaning, the live weights of eight-week-old rabbits in the control group and E group were 727 g and 743 g, respectively. The weaned rabbits of the E group were further equally divided into two post-weaning experimental dietary groups (M = 12; G = 12); these diets contained a 20% share of white lupine seeds each and their composition only differed in the type of the binder (molasses or glycerol component). The rabbits of the control group received a commercial pet rabbit diet with no white lupine seeds during the entire experimental period. At the age of eight weeks, the diet showed a significant effect on the level of albumin (P < 0.05), A/G ratio (P < 0.05) and ALP activity (P < 0.01) in plasma of dwarf rabbit kits. Significant effects of diet were found in 15-week old rabbits in relation to the plasma level of albumin (P < 0.05), Ca (P < 0.05), A/G ratio (P < 0.05) and ALT activity (P < 0.01). The dietary inclusion of white lupine seeds resulted in beneficial health effects on certain blood indicators of rabbits, and their use in the proportion of 25% in the pre-weaning diet and 20% in the post-weaning diet can be recommended as a suitable feed additive for dwarf rabbits. The use of crude glycerol as binder in the experimental diet had no adverse effect on the blood indicators of the growing rabbits and thus it can be recommended for the manufacture of feed pellets intended for dwarf rabbits.

Performance Results and Concentrations of Biochemical Indices and Mineral Elements in Blood Serum of Fatteners Fed Diets Containing Mixtures of Raw Seeds of Pea (Pisum sativum L.) or Blue Lupin (Lupinus angustifolius L.)

“…Damage of cells, hepatocytes in particular, leads to their leakage from damaged cells, which increases their level in blood plasma [39]. According to Šimek et al [40], diet supplementation with white lupin seeds can have a positive impact on the life cycle of cells by protecting them against excess degradation, which was confirmed in the present study wherein blood levels of ASPAT and ALAT were shown to decrease (Experiment II).…”

Selected blood biochemical indicators of Cherry Valley ducks undergoing fattening in relation to their diet and sex

“…The dietary effect of white lupine seeds on the blood biochemistry profile of hybrid mallard ducks, including an assessment of the serum protein fractions, has not yet been reported in the literature. Since previous studies have proven the dietary effects of lupine seeds on some biochemical indicators in chickens (Viveros et al 2007) and other animals (Martins et al 2005;Bettzieche et al 2008;Simek et al 2018), it can be expected that this effect exists also in fattening ducks. For that reason, the purpose of the present study was to assess the dietary effect of partial (50%) and complete replacement of soybean meal with meal of whole seeds of white lupine, Zulika variety, on selected blood plasma biochemistry indicators and serum protein fractions of Cherry Valley ducks undergoing fattening at the age of 40 days.…”

Dehulling effect of dietary administered white lupine seeds on the blood biochemistry of broilers

“…Besides that, within both trials of the present study, the males showed a higher plasma Glu concentration compared to https://doi.org/10.17221/27/2020-VETMED (2019) in broilers and also by Jerabek et al (2018) in fattened meat-type mallard ducks, when likewise the partial or complete dietary replacement of the SBM with the meal from whole WL seeds was used. Simek et al (2018) found that partial dietary inclusion of WL seeds also showed a TAGlowering effect in pet rabbits. Recently, Bettzieche et al (2008) revealed that the TAG-lowering effect of lupin seeds is caused by the downregulation of the fatty acid synthesis genes and the upregulation of the genes involved in the TAG hydrolysis.…”
