An 8-week trial to examine the impacts of Arthrospira platensis and Chlorella vulgaris on the growth, nutrient aspects, intestinal efficacy, and antioxidants of 75 New Zealand white male rabbits (initial body weight = 665.93 ± 15.18 g). Herein the study was designed in one-way ANOVA to compare the effects of the two algae species with two levels of supplementations in the feeds of New Zealand white rabbits. The rabbits were divided into five groups (n = 15/group), where the first group was allocated as the control group (Ctrl) while the second and third groups received A. platensis at 300 or 500 mg/kg diet (Ap300 or Ap500). The fourth and fifth groups fed C. vulgaris at 300 or 500 mg/kg diet (Ch300 or Ch500). The basal diet rabbits exhibited the lowest values of weight, lipase, protease, and the highest feed conversion ratio, which improved noticeably with algae addition, particularly with Ap500, Ch300, and Ch500. All tested groups showed normal intestinal structure. Amylase potency, hematological indicators, and serum biochemistry revealed non-significant variation except for a higher serum total protein and lower total cholesterol in algal groups. The best GPx existed in groups fed algal diets, while favorable SOD and CAT efficiency occurred at the higher level of Arthrospira and both levels of Chlorella. In conclusion, incorporating Arthrospira or Chlorella in the diet of New Zealand white rabbits improved performance, nutrient utilization, intestinal efficacy, and antioxidants. Arthrospira (Ap500) and Chlorella (Ch300 or Ch500) have almost the same beneficial effect on rabbit performance.

“…Feed restriction and strategies to limit the ingestion of young rabbits were used to minimize digestive disorders and reduce post-weaning mortality by increasing feed efficiency (Gidenne et al, 2012b;Birolo et al, 2016;Alabiso et al, 2017;Birolo et al, 2020). This strategy is associated with the reduction of feed costs (Maertens, 2009) and improving feed efficiency (Gidenne et al, 2017(Gidenne et al, , 2019Martignon et al, 2021) without impairing growth, slaughter and carcass traits (Birolo et al, 2021). However, the feeding-restriction strategies and levels are not completely unified and continue to be studied (Birolo et al, 2021;Martignon et al, 2021;Tůmová et al, 2022aTůmová et al, , 2022bZhuang et al, 2022).…”

This work was carry out to study the effects of dietary restriction by limiting rabbit access to the feeder on fattening performance. A total of 44 weaned rabbits, of 32-35 days, were randomly divided into 2 groups, the control group (C) fed ad-libitum throughout the fattening period and the group with restricted access to the feed restriction (R). The weekly feeding program of the R group consisted of a restricted access time to the feed trough for 5 days (3h/d) and an ad libitum feed distribution for the weekend during the 5 weeks post-weaning. Two weeks before slaughter (10 to 12 weeks of age), the rabbits from the Group R were fed ad libitum. Results showed lower live weights for Group R at 10 weeks of age (R: 1084.7 g vs. C: 1510.7; p<0.05) but similar at 12 weeks of age (R: 1557.2 g vs. C: 1800.9 g; P>0.05). Different daily feed intakes throughout the fattening period and similar average daily gains (R:16.25 g/d vs. C:22.10 g/d; p>0.05). The feed intake index at the end of fattening was significantly higher in control animals (C:4.15 vs. R:3.85, p=0.001). Carcass yield was similar (C: 68.07% vs. R: 65.70%; p>0.05), peri-renal fat weight was higher in control rabbits (C: 27.17g vs. R: 13.67g; p=0.002).The results of the present study indicate the economic interest of using a feed restriction strategy that could be popularized in local rabbit farms.

“…Restricted feeding is the approach to limit the calorie intake to attain particular digestive and physiological characteristics depending on the growth and development of an individual [ 1 ]. Though ad libitum feeding is usually applied during rabbit rearing, it has been the major cause of feed waste and a high incidence of digestive diseases and mortality [ 2 ]. Regardless of retaining the advantages such as reduced diarrhea and low mortality in young rabbits, the excessive nutritional restriction can also lead to reduced growth and low performance of rabbits [ 3 ].…”

This study aimed to explore the effects of different feeding restriction levels on the growth performance, intestinal immunity, and skeletal muscle development of meat rabbits. Additionally, we studied whether complete compensatory growth could be obtained post 2 weeks of restricted feeding, in order to seek a scientific mode of feeding restriction. Each of three groups was exposed to 3 weeks of feeding restriction and 2 weeks of compensatory growth. The 15% feeding restriction showed a negligible effect on the final body-weight of the rabbits (p > 0.05), but significantly reduced the feed-to-weight ratio (p < 0.05); reduced diarrhea and mortality; and increased digestive enzyme activity and antioxidant capacity. However, a 30% feeding-restriction level substantially reduced the growth rate of the rabbits (p < 0.05), impaired skeletal muscle development, and showed no compensatory growth after 2 weeks of nutritional recovery. Additionally, immunoglobulin and antioxidant enzyme synthesis were impaired due to reduced nutritional levels, and levels of pro-inflammatory factors were increased during the compensation period. The IGF1 mRNA expression decreased significantly (p < 0.05), whereas MSTN and FOXO1 expression increased noticeably (p < 0.05). Moreover, protein levels of p-Akt and p-p70 decreased significantly in the 15% feeding restriction group. Overall, the 15% feeding limit unaffected the weight and skeletal muscle development of rabbits, whereas the 30% feeding limit affected the growth and development of skeletal muscle in growing rabbits. The PI3K/Akt signaling pathway is plausibly a mediator of this process.
