“…In a previous study (Angel et al, 1985), a dietary coccidiostat, Stenorol®, was found to induce a high percentage of skin tears, and the skins were less resistant to tensile forces. In that study, the extremely high percent of skin tears was found to be an abnormal phenomenon.…”

Skins from male and female broilers, aged 6.5 to 8.5 weeks at slaughter, fed on the different energy:protein (E/P) rations, were measured for fat content and tensile strength.Tensile strength of both male and female broiler skins increased with age. The tensile strength of male skins was higher than that of females (1078 g vs. 842 g, average, respectively). Female skins contained more fat than males (36.9 vs. 32.2%, average, respectively). Dietary E/P rations did not consistently affect skin fat content or tensile strength.In spite of the skin's fat tendency to increase with age, tensile strength increased with age. Therefore, other factors play a role in determining tensile strength in broilers. (

“…Angel et al [6] reported that one anticoccidial (HAL) significantly increased the percentage of skin rips in female broilers compared with those fed the other anticoccidial (MON). Although MON was not used in the comparison, feeding HAL in the starter feed, alone or with salinomycin, reduced the skin puncture strength of broilers at 21 d of age, and this continued through to d 35 [8].…”

“…Similarly, Ruiz et al [5] noted that optimal broiler performance was achieved with the wheat-based diets when balanced to be isocaloric and to contain similar levels of Lys plus TSAA. Several researchers have studied the possible effect of anticoccidials on broiler skin quality, noting that some anticoccidials negatively influence skin quality [6][7][8][9]. Angel et al [6] reported that feeding halofuginone (HAL) significantly increased the percentage of skin rips in female broilers compared with those fed monensin (MON).…”

Glutamic acid may play a role in skin integrity, which could influence carcass quality. A study was undertaken to determine if supplementing l-Glu would influence the live performance and carcass quality of broilers when using different cereal and anticoccidial sources. The study consisted of 2 cereal sources (wheat or corn), 2 l-Glu levels (0 or 1.75%), and 2 anticoccidial sources (monensin or halofuginone), for a total of 8 treatments with diets meeting or exceeding nutrient recommendations for essential amino acids and energy for the starter (0 to 17 d of age), grower (18 to 43 d of age), and finisher (44 to 48 d of age) feeds. Each dietary treatment was fed to 4 replicate pens of birds containing 33 chicks/pen at the time of placement. Adding l-Glu to the starter diets with monensin improved FE regardless of the cereal source; however, the opposite was true for halofuginone. Feed efficiency at d 43 and 48 was improved with added Glu, although during the grower period, cereal and anticoccidial sources did influence FE independently. Bruising of wings and drumsticks, and back skin problems were influenced by anticoccidial source. Adding Glu reduced drumstick deformities, especially when halofuginone was used in the diets. Yields of breast fillets and tenders were significantly greater for corn-fed vs. wheat-fed broilers. Breast fillet yield (g) was lower for broilers fed halofuginone. Drumstick yield (%) was increased with the addition of Glu to the diet. Supplementing the diet with Glu reduced carcass defects, which may reflect the need for Glu in connective tissue formation during rapid growth. The benefit of Glu may depend on the anticoccidial and cereal sources used.

“…Tensile strength of skin is highly correlated to skin tearing which is a costly problem in the broiler industry resulting in downgrades of broilers (Angel et al, 1985;Schleifer, 1988). In severe cases frequency of skin tearing increases about 60% in a flock (Cahaner et al, 1993) and may cause muscle shredding of up to 5.7% in the female birds (Pitcovski et al, 1994).…”

The influence of supplementing diets with various levels of organic zinc (OZ) on the performance, meat quality attributes, and sensory properties of broiler chickens was investigated. A total of 3,200 1-d-old female broiler chicks were randomly allotted to 16 floor pens (replicates) with 200 birds per pen. A corn-wheat-soybean meal basal diet (control) was formulated and 20 ppm OZ (20 OZ), 40 ppm OZ (40 OZ), or 80 ppm OZ (80 OZ) was added to the basal diet to form four dietary treatments with four replicates per treatment. Live performance of broiler chickens, meat quality, and sensory properties were evaluated. The results showed no significant difference among the treatments for live performance of broiler chickens. Significant increases (p<0.05) in thigh skin epidermis and dermis thickness were shown in the OZ supplementation groups; however, no effect of OZ on the thickness of back skin epidermis or dermis was found. Dietary OZ levels did not affect the pH of breast and thigh meat or the water holding capacity (WHC) of thigh meat, but the WHC of breast meat increased significantly (p<0.05) when birds were fed 40 OZ and 80 OZ. Results of a sensory analysis showed no differences among the dietary treatments. In conclusion, dietary OZ did not affect live performance or sensory properties of broiler chickens but did increase the WHC of breast meat and thickness of skin layers; thus, improving carcass quality in broiler chickens.
