Effects of calcium to non-phytate phosphorus ratio and different sources of vitamin D on growth performance and bone mineralization in broiler chickens

Jincheng Han, Jianguo Wang, Guanhua Chen, Hongxia Qu, Jinliang Zhang, Chuanxin Shi, [...]

DOI: 10.1590/S1806-92902016000100001

A 7 × 2 factorial experiment was designed to test the effects of calcium (Ca) to non-phytate phosphorus (NPP) ratio (1.14, 1.43, 1.71, 2.00, 2.29, 2.57, and 2.86) and different sources of vitamin D (1α-hydroxycholecalciferol (1α-OH-D3) and 25-hydroxycholecalciferol (25-OH-D3)) on growth performance and bone mineralization in 1- to 42-d-old broiler chickens. On the day of hatch, 700 female Ross 308 broilers were weighed and randomly assigned to 14 treatments with five stainless steel cages of 10 birds each. Dietary Ca […]

Keywords: 1α-hydroxycholecalciferol; 25-hydroxycholecalciferol; broiler chicken

DOI: 10.1590/S1806-92902016000100002

This study was conducted to compare live weight, feed intake, feed conversion, mortality rate, and some carcass characteristics of Japanese quails reared under organic and conventional conditions. A total of 180 one-day-old quail chicks were randomly divided into six groups ― Conventional, consuming conventional feed ad libitum; Control (C), consuming organic feed ad libitum; C+P, consuming organic feed ad libitum + pasture; 80C+P, consuming 80% of control + pasture; 70C+P, consuming 70% of control + pasture; and 50C+P, consuming 50% […]

DOI: 10.1590/S1806-92902016000100003

This study investigated the effect of a supplement containing whole rice bran and crude glycerin for 21 days before mating on metabolic, productive, and reproductive responses of 28 primiparous suckling beef cows. Cows were randomly assigned to a control group (CON, n = 14), grazing on grasslands, and a supplemented group (SUP, n = 14), grazing on grasslands and supplemented daily individually with 1 kg dry matter (DM) of whole rice bran + 550 mL crude glycerin (224 g kg−1 […]

DOI: 10.1590/S1806-92902016000100004

The objective of this study was to evaluate the effect of replacing wheat bran by spineless cactus (0, 25, 50, 75, and 100%) in sugar cane-based diets on intake and nutrient digestibility and ruminal parameters of sheep. Five sheep (Santa Inês; average initial weight of 34.0±3.6 kg) were fitted with cannulas in the rumen and then assigned to a 5 × 5 Latin square design. The maximum dry matter (DM; 1414 g d−1), digestible organic matter (658 g d−1), and […]

Crude glycerin levels in pearl millet-based diets for Nellore young bulls in feedlot

Werney da Silva Moreira, Fabrícia Rocha Chaves Miotto, João Restle, Regis Luis Missio, José Neuman Miranda Neiva, Roger Vieira Moreira

DOI: 10.1590/S1806-92902016000100005

The objective of this study was to find the best level of inclusion of crude glycerin (0, 60, 120, and 240 g kg−1 of dry matter of diet) in substitution of pearl millet in a feedlot diet. Twenty-eight Nellore young bulls with mean age of 18 months and average weight of 357±23.56 kg were used. The animals were distributed in a completely randomized design with four treatments and seven replications. The intakes of dry matter, crude protein, neutral detergent fiber, […]
