Effect of Fat Sources and Emulsifier Supplementation in Broiler Starter, Grower and Finisher Diets on Performance, Nutrient Digestibility, and Carcass Parameters

Abstract

The purpose of this study was to evaluate the effect of fat sources and emulsifier supplementation in different phases on growth performance of broilers. Treatments were; (T1) basal ration (BR) which contained soy oil (SO) and had inclusion of emulsifier for whole life, (T2) BR which contained poultry fat (PO) and had inclusion of emulsifier for whole life, (T3) BR which contained oxidized oil (OO) and had inclusion of emulsifier for whole life, (T4) BR which contained SO and had inclusion of emulsifier during starter phase (T5) BR which contained PO and had inclusion of emulsifier during the starter phase, (T6) BR which contained OO and had inclusion of emulsifier during the starter phase, (T7) BR which contained SO and had inclusion of emulsifier during the starter phase (T8) BR which contained PO and had inclusion of emulsifier during the grower phase, (T9) BR which contained OO and had inclusion of emulsifier during the grower phase, (T10) BR which contained SO and had inclusion of emulsifier during the finisher phase, (T11) BR which contained PO and had inclusion of emulsifier during the finisher phase (T12) BR which contained OO and had inclusion of emulsifier during the finisher phase. The Basal ration which contained SO and supplemented emulsifier during the grower phase and throughout life increased the body weight gain. The supplementation of emulsifier in the finisher phase and throughout life in a diet which contained SO had better feed conversion ratio. The supplementation of emulsifier in the finisher phase and throughout life in SO based diet increased the dry matter and crude fat digestibility. We recommend emulsifier supplementation in the finisher phase for the economic point of view.

Mycoplasma pathogenicity for humans and animals: an effort of complete genome sequencing and gene family analysis of Mycoplasma synoviae

“…Feeding and management: Birds were fed on the standard feed as described in the literature (Hussain et al, 2018;Xu et al, 2019;Arshad et al, 2020;Bajwa et al, 2020;Kamran et al, 2020;Shahid et al, 2020;Shahid et al, 2021). Birds were managed according to standard procedure as described in literature (Hussain et al, 2018;Xu et al, 2019).…”

Potential of feeding fresh and conserved mulberry leaf in ruminants and its impact on dry matter intake, digestibility, milk production, milk composition and meat quality: A review

“…With the advancement of human society and the rapid development of agriculture and animal husbandry, the demand for meat, milk, eggs, and poultry food products for human consumption have been rising, and thus, food safety and security awareness is increasing (Aziz ur Aziz ur Rahman et al, 2019;Arshad et al, 2020;Bajwa et al, 2020). There is often a shortage of high-quality protein feed and an insufficient supply feed ingredients and green forage during the winter and spring feeding season both in poultry and livestock (He et al, 2018;Hussain et al, 2018;Hussain et al, 2020;Kamran et al, 2020). This greatly limits the output of livestock and poultry food products, and it threatens the safety and security of livestock and poultry food production (Muhammad et al, 2016;Niu et al, 2017;Muhmmad et al, 2020).…”

Transcriptomic analysis of differentially expressed genes between uterus and ovary in Xiangxi cattle

“…Therefore, conducting research on the expression of genes related to the development of ovary and uterus can pave the way to understand the key role of these genes in development and growth of beef cattle. Kamran et al, 2020;Riaz et al, 2021a;Riaz et al, 2021b;Shahid et al, 2021) has been conducted on indigenous feed resources, and livestock breeds. Similarly, a lot of research has been conducted and the results in terms of phenotypic traits, genetic characterization, providing some information for breed identification and genetic marker mining.…”
