Nutrient composition of the feed and feedstuff
Chemical analysis of the feed and feed components is shown in Table 2. The pellets’ dry matter content slightly increased as more moringa and chaya were added, but the organic matter content was the same for all treatments. T2 pellets had a greater ether extract concentration. As is frequently noted for diets based on tree leaves, the structural part from chaya and moringa leaves may have contributed to the somewhat greater ADF and NDF concentrations seen in enrichedpellets (
Van Soest et al., 1991).
Dry matter intake showing in Table 3. which grew gradually over the course of the trial and was greatly impacted by dietary interventions. Kids who were given mixed pellets of moringa and chaya had greater (P<0.05) DMI than the control group. T2 had the greatest intake (458.18±8.98 g/day), followed by T1 (426.52±8.14) and T0 (409.09±6.5). Better palatability and improved nutrient balance of the chaya and moringa mixed pellet diets may have improved DMI in T1 and T2 groups which enhance rumen fermentation efficiency and rate of digesta passage
(Totakul et al., 2021). Aregheore (2002) and
Moyo et al., (2011) showed high Dry Matter Intake in goats fed moringa-based diets, reason being the effect of improved palatability and better nutrient composition. Similar results were reported by
Asaolu et al., (2012), while
Tona et al., (2014) noted increased total DMI with higher inclusion of moringa leaf meal. No change in DMI seen by
Damor et al., (2017) when moringa replaced concentrate mixture, this study suggests that combining chaya and moringa produced a more balanced and digestible nutrient profile, increasing acceptability and intake.
Table 4 depicts the fortnightly body weight gain of Barbari kids. It showed remarkable differences (P<0.05). Barbari Kid’s fortnightly body weight gain revealed considerable differences (P<0.05) between treatments, with T2 having the highest overall average body weight (10.01 kg), than T1 (9.35 kg) and T0 (9.25 kg), suggesting a favourable reaction to supplementation with mixed pellets of moringa and chaya.
Aregheore (2002) showed differences in live body weight gains in goats receiving a 20% moringa diet, this study also coroborate with other results showing the beneficial effects of moringa supplementation on growth in goat kids as, while differential growth when moringa replaced sunflower seed cake at divergent inclusion levels observed by
(Sarwatt et al., 2002). Moyo et al., (2011); Tona et al., (2014); Babiker et al., (2017); Damor et al., (2017) got similar developments. Furthermore,
Ali (2018) and
Ahmed and Shaarawy (2019) demonstrated that little replacement of usual protein sources with moringa meal either sustained or increased growth in goats. Replacing 75% of concentrate with chaya meal showed no detrimental effect on dry matter intake
(Kumar et al., 2010), while
Singh et al., (2013) observed that substituting 50% of crude protein with chaya kept up normal weight gain, though higher replacement levels showed reduced performance. The mutual benefits of the variable components of chaya and moringa responsible for the increased growth seen in the T2 class. These substances probably improved fibre decomposition, increased rumen microbial activity and promoted more effective nutrient absorption.
Haematological and biochemical parameters
Hb, TEC, TLC and platelet counts were drastically affected (p<0.05) across groups (Table 5). The higher Hb levels observed in T1 and T2 might be due to the rich iron, essential amino acids, provitamin A and antioxidant content of
Moringa and
Chaya leaves, which promote red blood cell formation. This is in line with
Meel et al., (2018), who also reported more Hb in Moringa-supplemented Sirohi kids. Similarly, the gradual rise in TEC, particularly in T2, could be attributed to the presence of iron, folates, β-carotene, vitamins and antioxidants that enhance erythropoiesis and protect red blood cells from oxidative damage.
Zaher et al. (2020) reported comparable increases in RBC and Hb with moderate Moringa inclusion, supporting the present findings. The TLC values remained within normal limits, consistent with
Meel et al., (2018) and
Damor et al., (2017), indicating no adverse immune response. The increase in PCV in supplemented groups further supports improved erythropoietic activity, likely due to the nutrient-rich and antioxidant properties of the leaves. Similar findings were reported by
Meel et al., (2018).
All serum biochemical parameters are presented in Table 6. Serum glucose was increasingly (p < 0.05) less in T1 and T2 than T0. This decline with increasing Moringa-Chaya supplementation may be due to the presence of hypoglycemic phytochemicals (flavonoids, phenolics and isothiocyanates), along with improved glucose utilization and insulin sensitivity. Similar trends were showed by
Meel et al., (2018) and
Zaher et al., (2020). Total protein showed a consistent increase with higher supplementation levels, likely reflecting the high-quality protein, better digestibility and enhanced metabolic efficiency of Moringa and Chaya, which support liver protein synthesis. This agrees with findings of
Babeker et al., (2015); Meel et al., (2018); Damor et al., (2017); Kholif et al., (2017). Albumin levels also high in T1 and T2, further indicating improved protein metabolism, consistent with earlier reports. Total cholesterol and triglycerides were significantly reduced in supplemented groups. Similar reductions have been done by
Babeker et al., (2015) and
Kholif et al., (2017). SGOT and SGPT levels did not show vast differences (p>0.05) among groups, suggesting no adverse effect on liver function, in line with
Srivastava et al. (2018). Serum calcium and phosphorus levels showed significant improvement with supplementation, supporting better mineral status. These findings matches with
Damor et al., (2017) for calcium and
Zaher et al., (2020) for phosphorus.
Overall, all haematological parameters remained within normal physiological ranges
(Barakat et al., 1967), suggesting that supplementation had beneficial effects without causing any health stress.
Faecal consistency score
The fortnightly faecal consistency scores of kids fed diets supplemented with Moringa and chaya pellets are shown in Table 7. A clear improvement in faecal consistency was observed with more levels of Moringa and Chaya supplementation. There was remarkable decrease in the FCS in T2 and T1 than T0.
The considerably (P<0.05) lower scores in T1 and T2 indicate that supplementation improved faecal firmness. The similarity between T1 and T2 suggests that even moderate inclusion of Moringa and chaya mixture positively affects stool consistency
(Gao et al., 2023).
Mortality and morbidity
Morbidity and mortality indices of Barbari kids are presented in Table 8. The control group showed 3 affections of diarrhoea, while the two in T1 and one in T2 group. Two mortality were documented within the control group, whereas no instances of mortality were observed in the treatment groups. It is plausible that reduced mortality may be linked to improved immune responsiveness, antioxidant defence mechanisms and possibly a direct anthelmintic effect of M. oleifera phytochemicals, which have been reported to reduce parasite fecundity and establishment
(Hoste et al., 2006) also the beneficial properties of chaya contributed to enhanced health in these groups by boosting their immune systems. Consequently, the overall morbidity rates were 37.5% in the T0 group, 25% in the T1 group and 12.5% in T2 groups. Similarly, the mortality rate was more pronounced in the control group (25%) in comparison to the treatment groups, which experienced no instances of mortality.
