“…We observed improved feed e ciency (FE) for the sh protein supplemented diets compared with the plant protein. The result is consistent with Hossain et al (2012) who explained that the better protein digestibility of the sh protein forti ed diets as well as increased e ciency of utilization of energy available in sh proteins were responsible for improved FE (Ali et al, 2001;Alali et al, 2011). This response, however, may not always be consistent with all the sh by-products used for feed formulation since the sources of protein may vary in property, i.e., the protein quality, digestibility, biological value, amino acid pro le, physical and chemical properties (Sing and Panda, 1992).…”

A 35-day trial was conducted to explore if different sources of dietary proteins at varying levels of metabolizable energy had any effect on the average daily feed intake (ADFI), average daily gain (ADG), feed efficiency (FE), carcass characteristics, cardio-pulmonary morphometry, gut morphology, profile of unsaturated fatty acid (UFA), saturated fatty acid (SFA), monounsaturated fatty acid (MUFA), polyunsaturated fatty acid (PUFA) and humoral immunity of the broiler birds. Total 288 Ross-308 day old male broiler birds were randomly distributed in four dietary treatment groups in a 2×2 factorial arrangement (Two different sources of proteins, i.e., plant and animal with two different levels of metabolizable energy, i.e., low and high). Each treatment had nine replicates containing eight birds per pen. Results indicated that, the supplementation of blended fish protein substantially increased (p<0.001) the final body weight and decreased (p<0.001) the ADFI at 1-14 d, 15-35 d and 1-35 d compared with plant protein. The ADG increased at 1-14 d (p<0.001), 15-35 d (p<0.05) and 1-35 d (p<0.05) and the FE improved (p<0.001) at 1-14 d, 15-35 d and 1-35 d. Similarly, the high energy diet significantly increased (p<0.001) the final body weight and decreased the ADFI at 1-14 d (p<0.001), 15-35 d (p<0.05) and 1-35 d (p<0.05) compared with low energy diet. The ADG increased (p<0.001) and the FE improved at 1-14 d, 15-35 d and 1-35 d. The animal protein increased the thigh weight (p<0.01), the neck weight (p<0.05) and the ratio (p<0.001) of ∑UFA:∑SFA and ∑PUFA:∑MUFA in the breast muscles of the broiler birds. The GLM identified no interaction effect (p>0.05) of energy and protein on the ADFI, ADG, FE, cardio-pulmonary morphometry and humoral immunity of the broiler birds against Newcastle and Infectious Bronchitis diseases. The RV:TV remained within standard range indicating no symptoms of cardiac dysfunctions. It was concluded that the fishmeal supplemented high energy diet improved weight gain, feed efficiency and meat quality of broiler by increasing ∑ω-3 and ∑ω-7 fatty acids as well as the ratio of ∑ω-3:∑ω-6, ∑UFA:∑SFA and ∑PUFA:∑MUFA in the breast muscles of the broiler birds.

“…Apparent ME values were expressed on an as-fed basis. Nitrogen content of feed was determined by the combustion method using a Leco TruMac N machine (Leco Corporation, St. Joseph, MI) and dietary CP was estimated using a factor of 6.25 ( Hossain et al, 2012 , Mutucumarana et al, 2015 ).…”

The effect of ME intake ( MEI ) on the reproductive system was evaluated. Ross 308 broiler breeder pullets (n = 140) were assigned to 2 treatments from 22 to 26 wk of age: (1) Low-energy diet fed restricted (2,807 kcal/kg, low MEI) and (2) high-energy diet fed unrestricted (3,109 kcal/kg, high MEI). Daylength was increased from 8 to 14 h at 22 wk of age with a light intensity of 30 lux. Daily palpation was used to detect sexual maturity via the presence of a hard-shelled egg in the shell gland. Expression of gonadotropin releasing hormone-I ( GnRH ) and gonadotropin inhibitory hormone ( GnIH ) genes in the hypothalamus and GnRH receptor ( GnRH-RI ) and GnIH receptor ( GnIH-R ) genes in the anterior pituitary gland of each pullet was evaluated from 22 to 26 wk of age using quantitative real time-PCR. Blood samples were taken weekly and luteinizing hormone ( LH ), follicle stimulating-hormone ( FSH ), and 17-beta-estradiol ( E2 ) determined using commercial ELISA kits. Carcass samples were used for determination of CP and fat content. Data were analyzed using the MIXED procedure in SAS, and differences were reported where P ≤ 0.05. High MEI treatment pullets had 2.3-fold higher GnRH and 1.8-fold higher GnRH-RI mRNA levels than low MEI pullets. MEI affected neither expression of GnIH and GnIH-R nor carcass protein content. For high MEI (489 kcal/D) and low MEI treatments (258 kcal/D), respectively, from 22 to 26 wk of age ( P ≤ 0.05), LH concentration was 3.05 and 1.60 ng/mL; FSH concentration was 145 and 89.3 pg/mL; E2 concentration was 429 and 266 pg/mL, and carcass lipid was 13.9 and 10.3%. The onset of lay for pullets in the high MEI treatment advanced such that 100% had laid by 26 wk of age compared with 30% in the low MEI treatment. We concluded that higher MEI advanced the activation of the hypothalamic–pituitary–gonadal axis and also increased body lipid deposition, and moreover, stimulated reproductive hormone levels which overall accelerated puberty in broiler breeder pullets.

“…Poultry (Gallus gallus domesticus Linnaeus, 1758) ranks second as the most consumed animal protein globally [207]. Protein in the chicken diet is often supplied from a mix of animal and plant sources [199,208], the latter of which is primarily from soybean due to its nutritional properties [209]. Although chickens grow faster with some animal protein in their diet, work has been conducted to observe the effects of using solely vegetablesourced protein for chicken [77,208,[210][211][212].…”
