Dietary supplementation with 15% tomato pomace (Solanum lycopersicum L.) improves sperm production and antioxidant status in aged male broiler breeders.

The objective was to investigate effects of dietary tomato pomace (TP) and L-Arginine (L-Arg; 10% above nutritional recommendation) in aged male broiler breeders. Thirty male broiler breeders (Ross 308), 58 wk old, were randomly and equally allocated into five experimental groups: basal diet (C); 5% TP-supplemented (T-5); 10% TP-supplemented (T-10); 15% TP-supplemented (T-15); and L-Arg supplemented (L-10) groups. In contrast to the Control and TP-supplemented groups, sperm of L-10 roosters had higher C14:1, C16:0 and C18:1 n-9c proportions, total saturated fatty acid (FA) contents, and n-6:n-3 ratios, but a lower C22:4 n-6 content (P<0.

This study aimed to investigate the effects of different dietary supplementation of tomato pomace (TP) and L-arginine (L-Arg) supplementation on sperm characteristics, reproductive performance, and semen biochemical components of aged commercial male broiler breeders. Thirty Ross 308 male broiler breeders (58 wk old) were provided and assigned to 5 dietary treatment groups, including control (CON), 5% TP (TPS-5), 10% TP (TPS-10), 15% TP (TPS-15), and L-Arg supplemented (10% above the recommendation, LAS-10). The results indicated that the semen volume increased in the TPS-15 group compared to that of the LAS-10 (and CON on wk 9) throughout the study (P < 0.

Potential application of Fe-methionine as a feed supplement on improving the quality of broilers breast meat.

A total of 250 one-day-old Ross 308 male chicks were used to investigate the effects of Fe-methionine (Fe-met) and iron sulfate (FeSO .7H O) on performance, mineral concentration, meat quality, and oxidative stability of breast. The feeding experiment was performed with five dietary groups including group I (basal diet [BD] + 80 mg/kg FeSO ), group II (BD + 60 mg/kg FeSO  + 20 mg/kg Fe-met), group III (BD + 40 mg/kg FeSO  + 40 mg/kg Fe-met), group IV (BD + 20 mg/kg FeSO + 60 mg/kg Fe-met), and group V (BD + 80 mg/kg Fe-met).

The impact of deoxynivalenol contaminated diet on performance, immune response, intestine morphology and jejunal gene expression in broiler chicken.

The aim of this study was to determine the effects of deoxynivalenol (DON) contaminated diet on performance, immune system, gut morphology and jejunal gene expression in broiler chickens. Eighty-one-day old chicks were randomly allotted into two treatments with 4 replicates (10 birds in each replication). Experimental diets were the control diet (maize-soybean meal) and an experimentally contaminated diet with 10 mg/kg DON.

Broiler responses to ferrous sulfate at different time periods: a comprehensive research on qualitative parameters of breast meat.

The objective of present study was to study the effects of dietary ferrous sulfate (FeSO) and time periods on Fe deposition, nutrients composition, color indices, water-holding capacity and oxidative stability of breast meat in broilers. This experiment was performed by 450 broilers in a 3 × 3 factorial design with 3 levels of supplemental Fe (0, 40 and 80 mg/kg) and 3 time periods (total, T: from 1 to 42 days; grower and finisher, GF: from 11 to 42 days and finisher, F: from 25 to 42 days). The results showed that increasing the iron supplementation to 80 mg/kg increased the breast meat crude Protein.

Growth and antioxidant status of broilers fed supplemental lysine and pyridoxine under high ambient temperature.

Three levels of lysine (90, 100 and 110% of Ross requirement) and of pyridoxine (3, 6 and 9 mg kg(-1)) were used in a 3 × 3 factorial experiment to investigate the growth and blood antioxidant ability of broilers under high ambient temperature. None of the dietary supplements affected the weight gain during the starter and grower periods. Although no significant differences were detected between the treatments during the entire period, high lysine level fed birds had a lower weight gain.
