Cottonseed Oil in Diets for Broilers in the Pre-Starter and Starter Phases

Abstract

The objective of this study was to evaluate the effect of different levels of crude cottonseed oil in isoenergetic diets, with or without supplementation of ferrous sulfate, on performance variables, relative weight of organs, and blood parameters of broilers, and on the economic viability of diets in the periods from 1 to 7 and 1 to 21 days of age. A total of 600 male birds of the Ross line were distributed in a completely randomized design in a (4×2) factorial arrangement with eight treatments (0, 2, 4, and 6% cottonseed oil with and without ferrous sulfate), and five replicates. The following variables were studied: feed intake, weight gain, feed conversion, weight of organs, blood parameters, and yield of carcass and cuts at 21 days. No effects of the levels of cottonseed oil were found on the performance of animals aged 1 to 7 days, or on the relative weights of the organs. In this same period, the weight gain, and the relative weights of heart, liver, and intestine of the animals that received ferrous sulfate were decreased, and feed conversion was worsened. In the period from 1 to 21 days, weight gain increased linearly with the increase in the levels of cottonseed oil. Blood parameters were not influenced by the diets. Crude cottonseed oil can be utilized in diets for broilers in the periods from 1 to 7 and 1 to 21 days of age at up to 6% of inclusion, and supplementation with ferrous sulfate is unnecessary if the differences in metabolization of the cottonseed oil are considered, with and without, it during the diet formulation process.

Influence of Thermally Oxidized Vegetable Oil and Animal Fats on Growth Performance, Nutrient Digestibility, Carcass Parameters and Meat Quality of Broilers

“…Prices of poultry feeds are increasing in developing countries due to higher prices of macro ingredients (corn and soybean) which contribute to a major portion of the feed. Sousa Lima et al, 2016), reported that the prices of most utilized raw materials for the formulation of diet fluctuates and it is vital to find the substitute of conventional ingredients especially corn and soybean to reduce the feed costs. Keeping in view the need for feed industry, different scientists are working on different alternative ingredients for poultry to reduce the cost of feed Yang et al, 2019) and oxidized oils are one of them.…”

Metabolizable Energy Levels for Meat-Type Quails at Starter Phase

“…Starter phase is marked by the immaturity of the gastrointestinal tract, which presents limited nutrient digestion and absorption capacity (Lima 2016). Lipids, in particular, appear to have its digestion and absorption more compromised among nutrients.…”

Lipid Sources in Diets for Hy-Line White Laying: Performance, Biometrics of Digestive Organs, and Bone Characteristics

“…Santos et al (2009) used three lipid sources (soybean, linseed, and cottonseed oils) at the inclusion levels of 2 and 4% of the diets of white-egg layers and found that their performance was not influenced by the treatments. Lima et al (2016) used different levels of cottonseed oil (0, 2, 4, and 6%) with and without addition of ferrous sulfate in pre-starter diets (1 to 7 days) for broilers and reported that no effects of the treatments were observed on the performance variables.…”

“…The composition of ingredients used in the formulation followed the recommendation of Rostagno et al (2011). The nutritional composition of cottonseed meal was obtained from Lima et al (2016), and that of sunflower seed from Fedna (2004).…”
