“…Bet was or was not substituted with 30% of supplemental dl ‐Met or l ‐Met according to its methyl‐donating property. Bet contains about 3.82 times methyl groups compared with Met (Fu et al, ). The lighting program was 23L: 1D, and feed and water were provided ad libitum throughout the whole experimental period.…”

This study aimed to evaluate the effects of dietary supplemental methionine (Met) source and betaine (Bet) replacement for Met on performance and activity of mitochondrial respiratory chain enzymes (MRCEs) in normal and heat‐stressed broiler chickens. Total of 1,200‐day‐old Ross 308 chicks were allocated to two houses, each consisted of 12 treatments, five replicates of 10 birds each with 2 × 2×3 × 2 (temperature × Met source × Met level × Bet, respectively) split‐plot factorial arrangement. Met level in the basal diets was 70% requirements (Req) that was increased to the requirement or 130% by supplemental dl‐ or l‐Met. Bet was or was not substituted at the rate of 30% supplemental dl‐ or l‐Met. Feed conversion ratio (FCR) in chicks fed 70% l‐Met was lower than those fed 70% dl‐Met diet during 1–10 days (p = 0.04). Broilers fed diets containing requirement or 130% Met, regardless of its source, showed higher weight gain (WG) than those received 70% Met diet during 11–42 days (p < 0.001). Feed intake (FI) of broilers fed 130% Met diet was decreased compared to other two groups during 11–42 days (p < 0.05). One hundred thirty percent Met requirement diet resulted in lower FCR comparing to other two groups during 11–42 days (p < 0.001). Heat‐stressed birds grew less than those under normal condition (p < 0.05). Broilers fed Req Met diet under normal temperature exhibited higher activities of complexes (Cox) I and III (p < 0.05). Cox I activity in heat‐stressed birds fed Bet + diet was similar to those fed Bet‐diet under normal temperature (p = 0.046). It is concluded that performance and the activities of Cox I and III were increased as the level of Met increased. Bet replacement for 30% supplemental Met resulted in similar consequences comparing to non‐Bet replacement diets on performance, but increased the activity of Cox III. l‐Met was effective than dl‐Met at the cellular level. High ambient temperature depressed performance and MRCE activity.

“…Betaine (Sigma Aldrich, St. Louis, MO) was substituted for 30% of supplemental DL-or L-Met according to its methyl donating capacity. Since betaine contains about 3.82 times more methyl groups than Met, supplemental Met was equivalently replaced by betaine (Fu et al 2016). The photoperiod was 23 L: 1 D (light: dark).…”

“…The increasing of embryo weight may be due to the increase in muscle mass as it is affected by administration of in-ovo feeding. L-Arginine was reported as one of the amino acids that could stimulate muscle development (Zhao et al, 2011;Fu et al, 2016). Based on this report, we assumed that in-ovo feeding of L-Arginine increased L-Arginine content in the muscle and resulting the increased muscle mass and heavy embryo.…”

The research was conducted to evaluate embryo development, post-hatch performances, and growth rate of kampung chicken treated in-ovo feeding of L-Arginine. A total of 135 kampung chicken fertile eggs (weight 42-43 g) were used and divided into 5 treatment groups of three replications. They were placed in the semi-automatic incubator. The first group was without in-ovo feeding (negative control); the second group was in-ovo feeding of saline 0.9% (positive control); the 3, 4, and 5 groups were in-ovo feeding of 0.5, 1.0, and 1.5% L-Arginine, respectively. In-ovo feeding of L-Arginine were injected into albumen on day 10 of incubation period using automatic syringe in the narrow end side of egg by inserting needle through a small hole at 10 mm depth. After hatching, all day old chicks were placed in floor pens (1 x 0.5 x 0.5 m) accordance with the previous egg groups. The results showed that in-ovo feeding of L-Arginine increased weight and circumference of the embryo, but did not affect the length of embryo. In-ovo feeding of L-Arginine resulted in a higher body weight gain and a lower feed conversion even though feed intake was not significantly different compared to the control groups. The growth rate performance up to 6 weeks rearing increased significantly by increasing L-Arginine administration to 1.0%. It can be concluded that embryo development and post-hatch performances of kampung chicken were markedly increased by in-ovo feeding of L-arginine.
