“…The findings of this study are also in line with the results of EL-Sabagh et al (2014), who reported that spirulina supplementation increased liveweights in fattening lambs from 47.0 to 55.3 kg and in growing pigs from 12.47 to 33.60 kg (Nedeva et al 2014). Also, in agreement with our results, Alazab et al (2020) found that adding SP to the diet of rabbits enhanced growth and performance and the FCR.…”

Context. Spirulina platensis (SP) has been found to be an important dietary supplement for boosting animal growth performance, having a high protein content (60-70% on a dry-matter basis) with minimal toxicity. Aims. The effect of Spirulina platensis (SP) supplementation on the growth and performance of two Omani goat breeds (Jabbali and Sahrawi) was investigated. Methods. Thirty-six 11-month-old bucks from two Omani goat breeds were studied for 70 days at the Livestock Research Centre, Ministry of Agriculture, Fisheries and Water Resources, Oman. Each breed was divided into three groups (n = 6) and fed one of the following three rations: (1) control (CON): concentrate with 14% crude protein and 11.9% energy (MJ/kg DM); (2) Treatment 1 (T1): the same concentrate with 2 g/head.day SP; and(3) Treatment 2 (T2): the same concentrate with 4 g/head.day SP. Weekly growth, performance and body conformation data collected included live bodyweight (BWT), body condition score (BCS), average daily gain (ADG), chest girth (CG), wither height (WH) and body length (BL). Key results. The Jabbali breed had a higher feed conversion ratio for T1 and T2 than did the Sahrawi breed. During the trial, no differences in total DM intake were found between treatments for either breed. T1 and T2 SP supplementation levels significantly (P < 0.05) improved the BWT and ADG of the Sahrawi breed compared with the CON group. Analysis of all traits indicated a significant (P < 0.05) effect of feeding spirulina on all the studied traits except WH and BL. ANOVAs for fixed effects in this study (dam age and kid birth type, i.e. single, twin or triple) were not significant (P > 0.05) for any of the studied traits. However, the breed effect was highly significant (P < 0.001) on BWT, ADG, BCS and treatment effect was significant (P < 0.05) on CG traits. Conclusions. Spirulina platensis could be used as a supplement feed to improve growth, performance and morphological traits in Omani goat production. Feeding spirulina to kids led to increased growth, herd performance and buck selection facilitation at an earlier age. Implications. These findings will benefit Omani goat producers in managing productivity and product quality.

“…upplementation of late pregnant ewes with Nannochloropsis induced a significant increased in WBCs, Hb, RBc count in the supplemented ewes and their newly born lambs as compared with the control group. The present study's findings were in line with those of (EL-Sabagh et al 2014) for fattening lambs and (Ghattas et al 2019) in calves, but they differed from those of (Alazab et al 2020) who discovered that all tested hematological parameters of growing rabbits treated with Spirulina platensis showed non-significant improvements when compared to the control group. Leukocytes play a vital role in nonspecific or innate immunity, and their numbers can be viewed as indicators of relatively low susceptibility to disease (Matanović et al 2007).…”

Nannochloropsis species should be given priority when it comes to microalgae that should be added to feed since they are suitable for intense culture and have a high concentration of PUFAs (especially EPA), antioxidants, and certain vitamins. This study investigated the possible immune and antioxidant impacts of Nannochloropsis supplementation on Barki ewes during transition period and their newly born lambs. Three weeks prior to the expected time of lambing, the researched ewes were divided into two equal groups of thirty ewes each. The second group, on the other hand, was fed the same base diet as the first group plus 10 g of commercially available Nannochloropsis powder per kg of concentrate, given daily to each ewe’s concentrate. Findings revealed that supplementation of ewes with Nannochloropsis significantly up-regulated the expression pattern of immune (NFKB, RANTES, HMGB1, TNF-α, IRF4, TLR7, CLA-DRB3.2, IL1B, IL6, CXCL8, S-LZ, and Cathelicidin), and antioxidant (SOD1, CAT, GPX1, GST, ATOX1, Nrf2 and AhpC/TSA) markers in ewes post-lambing and their newly born lambs. Additionally, mRNA levels of lipogenic (ACACA, FASN SCD, LPL, and BTN1A) markers were significantly up-regulated in lambs from supplemented ewes than control ones. There was a significant increase in the WBCs, Hb, RBc count, serum level of glucose, total protein, triacylglycerol and total cholesterol, GPx, catalase, IL1α and IL6 with significantly decreased serum level of TNF-α and MDA in supplemented ewes after lambing as compared with control ones. There was also a significant increase in WBCs, Hb, RBc count, birth weight and body temperature with significantly decreased in the serum levels of TNF-α and stillbirth of newly born lambs from supplemented ewes as compared to other lambs from control ones.

“…Several studies have demonstrated that adding algal biomass or extracts improves growth and nutrient use. In Arthrospira impacts regard, Alazab et al 20 found that adding Spirulina platensis (SP) to the diet of growing rabbits at a level of 0.6 g/kg diet resulted in considerably better growth performance parameters and enhanced feed conversion ratio in comparison to those provided the low level (0.3 g/kg diet) or those fed a basal diet. Moreover, Aladaileh et al 21 highlighted that exogenous supplementation of SP enhanced the growth traits of rabbits subjected to Pb.…”

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.
