“…Regarding the effect of herbal extract addition on the incidence of growth-related breast muscle abnormalities, our results were partially in agreement with previous studies. Mudalal et al [ 29 ] found that the incidence of WS was 19.5–39.2% and that WS combined with WB was in the range of 67–76.5% at a slaughtering age of 41 days. Previous studies showed that the incidence of WS was 25.7–32.3% [ 20 ].…”

The objective of this study was to investigate the effects of thyme and oregano essential oils (as growth promotors), individually and in combination, on the health, growth performance, and prevalence of muscle abnormalities in broiler chickens. Six hundred day-old Cobb 500 hybrid chickens were randomized into four dietary treatment groups with three replicates each. Chicks in the control group (C) received a basal diet, while the experimental treatment groups received basal diets containing 350 mg/kg of thyme oil (T1), 350 mg/kg of oregano oil (T2), and 350 mg/kg of thyme and oregano oil (T3). Growth performance parameters were evaluated at 14, 28, and 42 days. The broilers in treatments T1 and T2 had significantly higher body weights than the control group. The feed conversion ratio was the lowest in chicks who received oregano oil, followed by those fed thyme oil. The overall prevalence of growth-related breast muscle abnormalities (including white striping and white striping combined with wooden breast) in groups receiving essential oils (T1, T2, and T3) was significantly higher than in the control group (C). The thyme and oregano oil diets showed no significant differences in antibody titers against Newcastle disease or interferon-γ (INF-γ) serum levels. In conclusion, thyme and oregano oils had a positive impact on the growth performance of broiler chickens but increased the incidence of growth-related breast muscle abnormalities.

“…In this context, Lorenzi et al (2014) found that the incidence of WS in medium-sized birds (1.5–2 kg) was 24.3% in females and 33.9% in males. Mudalal et al (2021) found that the incidence of WS in broilers fed standard feed was 38.5% while it was 28%–30% in broiler fed herb extract enriched feed at slaughter age of 34 d.…”

The aim of this study was to assess the occurrence of white striping (WS), wooden breast (WB), and WS combined with WS/WB muscle abnormalities in broilers (Ross 500) at different slaughter ages (34, 41, and 48 d). In addition, the influence of these muscle abnormalities at different slaughter ages on quality characteristics (physical dimensions, pH, color index, and chemical composition) was studied. Overall occurrence of muscle abnormalities was 45%, 92%, and 100% at slaughter ages of 34, 41, and 48 d, respectively. It was found that about 39% from the occurrence of muscle abnormalities was not similar in the same bird (left and right fillets). Breast fillets affected by muscle abnormalities had significantly (p<0.05) higher weight than normal fillets. At slaughter age of 34 d, normal fillets had significantly higher L* (67.37 vs. 61.73 and 63.05, p<0.05), lower a* (3.25 vs. 4.87 and 5.18, p<0.05) and b* (4.02 vs. 5.20 and 5.99, p<0.05) than WS and WS combined with WB fillets; respectively. The changes in chemical composition due to muscle abnormalities were more significant at high slaughter age than at low slaughter age. In conclusion, the occurrence of muscle abnormalities was strongly influenced by slaughter age. Moreover, breast fillets affected by muscle abnormalities had different quality characteristics (proximate composition, color traits, and dimensions) in comparison to normal fillets.

“…It has been revealed to possess anticancer, antidiabetic, anti-hepatotoxic, anti-inflammatory, antibacterial, and antioxidant activities [33]. The use of the plant meal as a supplement in the diets of chickens is documented [1,27,37], however, there is a paucity of information on its effect on reproduction parameters. It is known that the inclusion of Chromolaena odorata leaf meal as feed supplements was non-toxic and did not suppress the growth of broilers but studies on the fertility of poultry are scarce.…”

Chromolaena odorata leaf meal (COLM) has been used to feed poultry without adverse effects on growth, however, studies on its effect on the fertility of local chicken are scarce. This study aimed at evaluating the effect of COLM-based diets on egg fertility, semen characteristic, and tissue biochemistry parameters (Protein, cholesterol, catalase (CAT), reduced glutathione (GSH), and malondialdehyde (MDA) concentration) of Brahma chickens. Sixty hens and fifteen cocks, aged 4-5 months were fed three dietary treatments T0, T1, and T2, as containing 0, 1 and 2% COLM, respectively in five replications for two months. Semen samples were collected once a week by double hand massage technique and semen quality parameters (volume, motility, concentration, and spermatozoa viability) were determined. Data on testicular and epididymis histology and biochemical parameters in testes were also collected during the eighth week of the experiment. During the incubation phase, fertility, and hatchability of eggs, as well as embryonic mortality of fertile eggs were recorded. The semen analysis showed that spermatozoa concentration and spermatozoa motility (p < 0.05) increased significantly with increased COLM supplementation levels. The biochemical analysis showed an increase in protein, cholesterol, and GSH levels while MDA levels decreased in males supplemented with COLM. The fertility percentage for T1 was significantly higher than in the other treatments, while hatchability and mortality of the embryo showed non-significant differences among the groups. The histopathological analysis also revealed a positive effect of the plant on spermatogenesis. Altogether, the addition of COLM up to 1% in local chicken diets improves semen quality, oxidative status level of testes, and egg fertility.
