Replacement level of rubber seed cake for soybean meal on the growth of Japanese quail

Abstract

A four-week feeding trial on the simultaneous replacement of 0 to 50% of soybean meal and 0 to 100% of soybean oil on the growth performance, carcass composition and profitability was conducted using 45 randomly chosen one-week-old growing Japanese quail. The five experimental diets were; D0= Diet containing 20% soybean meal and 4% soybean oil (control diet), D1= Diet, where 12.5% of soybean meal and 25% of soybean oil has been replaced by RSC; T2 = Diet, where 25% of soybean meal and 50% of soybean oil has been replaced by RSC; T3 = Diet, where 37.5% of soybean meal and 75% of soybean oil has been replaced by RSC; T4 = Diet, where 50% of soybean meal and 100% of soybean oil has been replaced by RSC. Results demonstrated that in raw rubber seed the proportion of kernel to hull is 64: 36. Proximate components of the boiled and sundried full fat rubber seed kernel (RS) were, moisture = 96.6%, ME = 5305 kcal / kg DM, CP = 17.6%, EE = 51.05%, CF = 8.5%, NFE = 18.25% and Ash = 4.6%. The body weights of the birds at 35 days of age in all dietary treatments were statistically similar. The feed intake of the quail among different dietary groups was varied significantly (p < 0.05) and there was a tendency of decreasing the feed intake at 25% and above inclusion level of RSC. The body weight gain and FCR were also statistically similar in all dietary groups. The feed cost and total production cost /kg BW of quail was also found to become steadily higher (p> 0.05) at higher RSC inclusion level. The muscle development was found to better at lower (%) RSC level, whereas the organs were enlarged at higher RSC inclusion. Results on the majority of the production parameters, and economics and carcass yield parameters suggested that the simultaneous replacement of maximum 50% soybean oil 25% soybean meal by processed RSC might be suggested, particularly, there will be a crisis in the availability of these two ingredients.

Performance, carcass quality and intestinal biometry of feed European quails with seaweed meal (Sargassum sp)

“…In addition to what has been said, the use of alternative foods for quails aims to reduce production costs and the reuse of waste discarded in agro-industrial processes, which must be available in quantity and quality, have good levels of micro and macronutrients, maintain or improve the productive performance, meat and egg quality and poultry welfare (Brunelli et al, 2018;Ferreira et al, 2019;Xavier et al, 2020;Nnadi et al, 2022).…”

Productive performance, egg quality and the morphometry of the organs of Japanese quails (Cotournix cotournix japônica) kept at different temperatures

“…High temperatures can hinder exploration and maximize quail production (Akdemir et al, 2019). Small environmental changes are perceived by birds (Castro et al, 2017;Santos et al, 2017;Furtado et al, 2022), causing an increase in the consumption of water and a reduction in feed consumption, which can reduce egg production and quality (Ferreira et al, 2019;Xavier et al, 2020;Nnadi et al, 2022).…”

“…The increase in water consumption is a way to replace the water lost through respiration, fecal and urinary excretion, to avoid dehydration, maintain homeotherm and minimize thermal stress (Scottá et al, 2017) but can negatively affect the production and quality of quail eggs (Nnadi et al, 2022). Laying quails produce good production in hot environments (Petrucci et al, 2017;Silva et al, 2017;Akdemir et al, 2019).…”

Marine macroalgae as an alternative in the feeding of broiler quails in an environment of thermal stress

“…One of the alternatives to maintaining production and profitability in poultry production is the use of alternative foods (Ferreira et al, 2019;Nnadi et al, 2022) and among these foods, seaweed stands out (Øverland et al, 2019;Michalak & Mahrose, 2020), such as green (Abudabos et al, 2013;Matshogo et al, 2020), red (Kulshreshtha et al, 2014), brown (Hafsa et al, 2019), green, Sargassum (Hafsa & Hassan, 2022), and Spirulina (Abouelezz, 2017), estimating that about 187 species of seaweed can be used for animal consumption, including 45 green, 35 brown, and 107 red algae (Shabaka, 2018).…”
