“…Mahrose et al (2015) indicated that different levels of protein in the diet had little effect on feed intake, body weight and weight gain in young ostriches. These authors found that birds at the age of 2-9 weeks did well with feed of a lower protein level (around 18%), which was later confirmed by Mahrose et al (2019).…”

To determine the effect of different dietary energy and protein levels on bodyweight and blood chemistry, 36 ostriches at 2 to 9 weeks of age for feeding conditions and 18 for blood chemistry parameters was used. The birds were divided into six treatment groups. Energy and protein levels of diet were 2400 and 2600 kcal/kg and 20%, 22%, and 24%, respectively. The feed intake and bodyweight gain were determined a weekly. Blood chemical parameters including glucose, HDL, LDL, total cholesterol, triglycerides, total protein, albumin, globulin, aspartate amino-transferase and alanine amino-transferase activity were determined. The highest weight gain during the whole experiment was observed in ostriches offered 2400 kcal · kg−1 dietary energy and 20% protein. The lowest level of total cholesterol and protein was observed in treatment V (2600 kcal · kg−1 dietary energy and 22% protein). The lowest level of glucose and triglycerides was noted after treatment I. The highest albumin and globulin concentrations were in treatment III (2400 kcal · kg−1 dietary energy and 24% protein) and treatment II (2400 kcal · kg−1 dietary energy and 22% protein), respectively. The energy level had no effect (P < 0.05) on feed intake and weight gain in all experimental period. The results of this study showed that with increasing energy and protein levels, most blood parameters increased in ostriches but total cholesterol did not.

“…Apart from these, chick mortality is also linked to stress, as a result of their inability to adjust to the rearing environment (Cloete Sri Lankan Journal of Biology 7(2) June 2022June et al, 2001. Evaluating the study farm against possible overcrowding revealed that it has a stocking density of 8.9 m 2 /individual which is ample space for normal growth and breeding of ostriches (Mahrose et al, 2019). Therefore, maintenance of balanced diet and external factors such as heat and moisture are vital for lowering mortality and in turn to prevent great economic losses in the ostrich farm.…”

Commercial ostrich farming for trading meat and feathers is relatively new in Nepal. This study investigated hatching success and chick mortality rates in the only commercial ostrich farm in Nepal- Ostrich Nepal Pvt. Ltd, Rupandehi, Lumbini Province, Nepal. The number of eggs laid, hatched and their mortality were observed from 2014 to 2020. Results revealed higher embryonic deaths than hatching percentage, however, chick’s mortality rate was comparatively lesser. Breeding population required more nutritional diet to ensure fertile eggs. Hatchability was affected by temperature, humidity and turning of eggs. Microbial contamination and infertility were the major contributors for embryonic death. Intense care is required for the young chicks as they are very vulnerable to heat, rain and infections. Nutrition, and proper temperature and humidity management are major aspects to foster the growth and development as well as to ensure better reproductive ability of ostriches in order to lower mortality and avoid economic loss.

“…Adding to low-protein diets with essential and/or nonessential amino acids was investigated ( Moosavi et al, 1994 ; Abdel-Hafeez et al, 2016 ). Feed consumption decreased when animals were under environmental heat exhaustion, resulting in lower protein and ME intake and, ultimately, a decline in all productivity and growth performance indicators ( Rehman et al, 2017 ; Mahrose et al, 2019 ).…”
