Effect of Sorghum Based Nutritional Programs on Performance, Carcass Yield and Composition of Breast in Broilers

Abstract

An experiment was conducted to compare three nutritional programs, which were developed with tannin-free grain sorghum based diets, evaluating performance, carcass yield and bromatological composition of the pectoral muscle of broilers. A total 1360 chicks mixed (50:50), from one to 42 days old Hubbard Flex Broilers, were housed in a completely randomized design consisting of treatments and 10 replicates each, distributed as follows: three programs with whole sorghum grain based diets (nutritional program with daily adjustment, nutritional program with every three days adjustment and nutritional program with four stages and a program with ground and whole sorghum grain based feed (four stages). The cumulative performance was evaluated at, 21 and 42 days, determining feed intake, weight gain, feed conversion and viability. At 42 days, the yield of eviscerated carcass, breast (full and boneless), thighs/drumsticks and wings and breast composition were evaluated. Nutritional adjustments showed better feed conversion, did not affect the carcass, commercial cuts yield and had a good breast meat quality. It can be concluded that daily feed programs could be performed in poultry industry with the mixture of whole sorghum grains and concentrates directly on farms contributing to better logistics and feed transportation cost.

Evaluation of Muscle Chemical and Amino Acids Composition in Broiler Chicks Fed Sorghum or Sorghum-Pea Diets

“…This is consistent with other studies that reported similar chemical composition of meat in broiler chickens fed sorghum (whole grain or ground) that replaced partially or totally corn (Garcia et al, 2005;Carolino et al, 2014) or in meat-type quail (Moraes et al, 2016). Comparing three nutritional programs with whole sorghum grain-based diets in Hubbard broilers, Silveira et al (2017) reported values to range from 23.39-23.66% for protein and from 2.6-2.68% for fat contents of breast meat. Similarly, Dotas et al (2014) found that the chemical composition of breast and leg muscles of Ross 308 broilers were not affected by feeding diets up to 480 g/kg field peas, depending on the age, as partial substitute of SBM and corn.…”

“…Fewer studies reported data on the chemical composition of broilers meat (Garcia et al, 2005;Carolino et al, 2014;Silveira et al, 2017) or meat quality, e.g., fatty acid profile, cholesterol, and vitamin A and E contents of meat (Ochieng et al, 2020) as an effect of feeding sorghum, or carcass and meat quality (Laudadio & Tufarelli 2010;Dotas et al, 2014;Biesek et al, 2020) by feeding peas diets. However, no studies were found about the AA profile of meat in broilers fed sorghum or sorghum-peas diets.…”

Performance and energy metabolisability of broiler finisher chickens fed red and white sorghum-based diets supplemented with methionine

“…Also, the red sorghum has been implicated in many studies to inherently contain high tannin content which could be the cause of the inferior performance of birds fed the diets. The results of this study are in consonance with those of Liu et al (2013), Silveira et al (2017), Saleh et al (2019 and Moritz et al (2022) that responses of broiler chickens to sorghum-based diets depends largely on variety/colour, with the white variety better utilised than others.…”

Impact of ß-Glucan with Non-Glucan Biomaterials on Growth Performance, Carcass Characteristics, and Viable Count of Lactobacilli in Broiler Chicks

“…Birds were slaughtered by the halal Muslim method (Dhabihah). Each bird was cut into different body parts according to the standard method for calculation of carcass weight, giblet weight (liver, heart, spleen, gizzard, and bursa), breast yield, and leg quarter yield (Silveira et al, 2017). Antibody titers were checked for Newcastle disease (ND) vaccine using hemagglutination (HA) and hemagglutination inhibition (HI) tests.…”
