Effects of a Hatchery Byproduct Mixture on Growth Performance and Digestible Energy of Various Hatchery Byproduct Mixtures in Nursery Pigs

Abstract

The objectives were to determine effects of a hatchery byproduct mixture (HBM) on growth performance and to measure digestible energy concentrations in various HBM. In the growth performance experiment, 96 pigs (initial body weight = 9.6 ± 0.8 kg) were assigned to 4 dietary treatments in a randomized complete block design with 6 blocks. Each treatment consisted of 6 replicate pens with 4 pigs comprising 2 barrows and 2 gilts. Pigs were fed graded concentrations of HBM at 0%, 3.33%, 6.67%, and 10.00% for 14 days. In the energy digestibility experiment, 10 barrows (initial body weight = 11.5 ± 0.4 kg) were employed to determine digestible energy in HBM. A basal diet based on corn and soybean meal and 4 additional diets containing 25% of 4 different HBM were prepared. The marker-to-marker method was employed for total collection and the experimental design was a replicated 5 × 4 Latins square design. Growth performance was not compromised as the inclusion rate of HBM increased up to 10%. Digestible energy of HBM ranged from 2772 to 3887 kcal/kg as-is basis. In conclusion, HBM can be used in nursery pig diets and different energy values should be used for each HBM.

Determination of metabolizable energy and amino acid digestibility in various hatchery byproducts for broiler chickens

“…In the current experiment, the CP concentrations in 4 HBPs ranged from 31.2 to 60.0%, which were closed to the values (32.2–66.3%) reported in previous experiments ( Sung et al, 2019 ; Sung et al, 2020 ; Sung and Kim, 2020 ). These results indicate that HBPs used in the current experiment are similar to those used in previous experiments.…”

“…The GE concentrations of MIX used in the current experiment were similar or lower than those reported in previous studies ( Rasool et al, 1999 ; Mehdipour et al, 2009 ; Sung et al, 2019 ). The variable GE concentrations in MIX result from different sources and inclusion amounts of individual HBPs, which are largely dependent of the hatchability in the commercial hatchery ( Rasool et al, 1999 ; Thaler and Holden, 2010 ; Sung and Kim, 2020 ). The MIX used in the previous studies contained relatively small amounts of HE, whereas the MIX used in this experiment contained 25% HE.…”

Additivity of digestible energy and nutrient concentrations in hatchery byproducts fed to nursery pigs

“…These wastes from hatchery facilities are known as hatchery byproducts [ 2 ] and are regarded as alternative protein sources in nursery pig diets. A hatchery byproduct mixture could replace animal protein sources without compromising growth performance of nursery pigs [ 3 ]. For these reasons, the use of hatchery byproducts in swine diets would be both economically and environmentally beneficial.…”

Application of extrusion-cooking technology in hatchery waste management

“…Currently, hatchery by-products are allowed in many countries including the United States and the European Union in animal feeds [ 4 , 10 ]. Nutrition studies revealed that properly processed HW can be a cheaper and very good substitute for animal protein sources such as fish meal and spray-dried plasma protein in animal feeds [ 1 , 2 , 5 , 9 , 11 ]. However, the high moisture content (MC) of the wastes and the specificity and presence of numerous microorganisms make it a highly unstable material.…”
