Effects of Pantothenic Acid Supplementation on Growth Performance, Carcass Traits, Plasma Parameters of Starter White Pekin Ducks Fed a Corn–Soybean Meal Diet

Abstract

This study aimed to evaluate the effects of different dietary pantothenic acid levels on growth performance, carcass traits, and plasma biochemical parameters of starter Pekin ducks from 1 to 21 days of age, as well as the pantothenic acid requirement of starter ducks. A total of 384 one-day-old male white Pekin ducklings were assigned randomly into 6 dietary treatments, each with 8 replicate pens of 8 ducks. Ducks were fed conventional basal corn–soybean diets containing 8.5, 10.5, 12.5, 14.5, 16.5, and 18.5 mg/kg pantothenic acid for 21 days. Growth depression, poor pantothenic acid status, fasting hypoglycemia, and elevated plasma uric acid (UA) content were observed in the ducks fed the pantothenic acid-deficient basal diet (p < 0.05), and these adverse effects were ameliorated by pantothenic acid supplementation. Among all ducks, the birds fed the basal diet with no supplementation of pantothenic acid had the lowest body weight, average daily weight gain (ADG), average daily feed intake (ADFI), breast meat yield, and plasma pantothenic acid and glucose contents (p < 0.05), and the greatest plasma UA content (p < 0.05). In addition, all these parameters showed a linear or quadratic response as dietary pantothenic acid levels increased (p < 0.05). According to broken-line regression, the pantothenic acid requirements of starter male white Pekin ducks for body weight, ADG, and plasma pantothenic acid content were 13.36, 13.29, and 15.0 mg/kg, respectively. The data potentially provides theoretical support for the utilization of pantothenic acid in duck production.

Muscle growth affects the metabolome of the pectoralis major muscle in red-winged tinamou (Rhynchotus rufescens)

“…Although animal selection promotes significant improvements in growth rates and meat production, a detailed understanding of muscle development is necessary in order to prevent physiological disorders, changes in composition of the muscle fiber type, and metabolic alterations that could influence meat quality ( Deeb and Lamont, 2002 ; Ruusunen and Puolanne, 2004 ; Aliabad et al, 2011 ; Tang et al, 2021 ). Within this context, metabolomics has been used to elucidate the biological mechanisms underlying muscle development related to the production of different bird species ( Wang et al, 2017 ; Ceribeli et al, 2018 ; Cônsolo et al, 2020 ; Ma et al, 2020 ; Basile et al, 2021 ), since metabolites are the intermediate products or end-products of complex cellular reactions and are sensitive markers of physiological activity ( Fontanesi, 2016 ; Zhang et al, 2022 ).…”

Pantothenic acid alleviates fat deposition and inflammation by preventing JNK/P38 MAPK signaling pathway

“…Some studies have shown that PA de ciency can result in convulsions, the adrenal gland, anemia, hypoglycemia, hyperventilation and tachycardia were also been impaired [24]. Such as, PA de ciency in poultry could cause fasting hypoglycemia, growth retardation, locomotor abnormalities, and high mortality [25][26][27][28]. Whereas, The PA de ciency in pigs displayed intestinal problems, spastic gait and several species endure nerve demyelination [29].…”
