Abstract Red oak Quercus spp., Subgenus Erythrobalanus acorns are forage for mallards Anas platyrhyncos, wood ducks Aix sponsa, and other wildlife that use bottomland hardwood forests in the southeastern United States. However, annual variation in true metabolizable energy from acorns would affect carrying-capacity estimates of bottomland hardwood forests for wintering ducks. Because gross energy and true metabolizable energy are strongly positively correlated and gross energy is easier to measure than true metabolizable energy, we used gross energy as a surrogate for true metabolizable energy

Abstract:

In the present investigation, N retention, AME, and AMEn data from six energy evaluation assays, involving four protein sources (soybean meal, full-fat soybean, rapeseed meal and maize distiller’s dried grains with solubles [DDGS]), are reported. The correction for zero N retention, reduced the AME value of soybean meal samples from different origins from 9.9 to 17.8% with increasing N retention. The magnitude of AME penalization in full-fat soybean samples, imposed by zero N correction, increased from 1.90 to 9.64% with increasing N retention.

Abstract:

This research sought to explore how different processing methods, including soaking and peeling the beans, and the introduction of protease enzyme and non-starch polysaccharides (NSP) enzymes, impact the nutrient content, metabolizable energy, and protein digestibility of processed Jack bean meal. The study utilized a completely randomized design, with four treatments and four replications. A total of 36 animals were involved, with 32 used for measuring metabolizable energy and protein digestibility, and 4 broiler chickens for endogenous measurement. Treatments included processed Jack bean mea

Abstract:

Media usage for Black Soldier Flies Larvae (BSFL) growth has not been standardized yet, and many research has tried to elucidate different substrates to produce optimal BSFL growth. This study aimed to analyse the effect of different media with different metabolizable energy and nutrient content, such as tofu waste (high metabolizable energy), Azolla microphylla (moderate metabolizable energy), and layer manure (low metabolizable energy), on the yield and nutritional properties of 19-d-old Black Soldier Fly Larvae (BSFL). We grew BSFL from egg to 19-d-old larvae and analysed the BSFL yields by

Red oak acorns (Quercus rubra), fruits of multiflora rose (Rosa multiflora), common juniper (Juniper communis), winterberry holly (Ilex verticillata), and barberry (Berberis spp.), fertile fronds of sensitive fern (Onoclea sensibilis), corn, and apples were fed as mixed rations to eight eastern wild turkeys (Meleagris gallopavo silvestris). Crude protein content of the foods ranged from 2 (apples) to 19% (sensitive fern). Red oak acorns and juniper berries were 14% fat; other foods were 1–7% fat. Apples were lowest in gross energy content (3.9 kcal/g dry matter (1 cal = 4.1868 J)), and sensiti

Abstract. The nature of biosynthetic processes and the productive qualities of ruminants depend on the level and ratio of substrates absorbed in the digestive tract. The maximum efficiency of the biosynthesis of meat components in the body is ensured if the amino acids enter the metabolic pool in sufficient quantity and in the optimal ratio. The purpose of the work is to study the needs of Aberdeen Angus meat bulls calves for metabolizable protein for the optimal use of amino acids and metabolizable energy of the diet for the increase in live weight of bulls-calves during the growing period.

Abstract:

A methodology to account for transformation of metabolizable energy and crude protein in compound feed for laying hens to energy and protein in egg melange (albumen and egg yolk) has been developed. The introduction of Clarc of metabolizable energy transformation and Clarc of crude protein distribution could help to more exactly account of net utilization of nutrients in the eco-technical feed chain. “Clarc” is the ratio of the nutrients studied between primary (feed) and secondary level (animal products, edible by humans). For their establishing, original formulas have been used. They could b

Thirty-two steers with an average initial body weight of 377.5 ± 49.4 kg were used, of which four were initially slaughtered to estimate the empty body weight (EBW) of the animals. Twenty-four steers were fed ad libitum and were distributed in a completely randomized design with two levels of concentrate (30 and 60 %), and diets with or without dicalcium phosphate and four steers were fed at maintenance level,
