Feeding behavior of goat kids fed diets containing peach palm meal

Abstract

The aim in this study was to evaluate the feeding behavior of goat kids fed diets containing peach palm meal replacing corn (0, 10, 40, 60, and 85 % on a dry matter basis). Thirty crossbred Boer kids, with 90 days old and initial body weight of 16.7 ± 3.5 kg were distributed in a completely randomized design with six replicates. Diets were daily supplied ad libitum to allow 10-20 % leftovers. Three collections were performed every 28 days. Diets were isoenergetics and isonitrogenous, composed of corn, soybean meal, peach palm meal, mineral supplement and Tifton 85 hay, with roughage: concentrate ratio of 30:70. There was a linear reduction in the intakes of dry matter (DM) and neutral detergent fiber (NDF) with a respective decrease of 35.7 % and 58.8 % comparing the diet with 85 % replacement and the control diet. The rumination and chewing times increased in diets with peach palm meal. The feeding and rumination rates decreased with reducing intakes of DM and NDF. The peach palm meal affects the feeding behavior and decreases the feed intake in response to palatability, fat and fiber composition, and it is recommended until 10 % replacing corn.

Perspectivas do uso de extratos de plantas amazônicas (açaí, copaíba, salva-do-marajó, pupunha e bacuri) como potenciais moduladores da fermentação ruminal: um breve panorama

“…Apesar de uma parte dos subprodutos da pupunha sejam destinados para utilização como ingredientes na dieta de animais ruminantes (38,51,52) , o teor de β-caroteno da pupunha, que atua como antioxidante e aumenta a produção microbiana in vitro (81) , pode possibilitar a utilização do óleo da pupunha como aditivo modulador da microbiota ruminal. Em razão disso, o desenvolvimento de estudos para avaliar os possíveis efeitos da utilização dos extratos de pupunha como aditivo no ambiente ruminal são fortemente encorajados.…”

PENGARUH PEMBERIAN SILASE CAMPURAN RUMPUT DAN DAUN MARKISA HUTAN DENGAN PROPORSI YANG BERBEDA TERHADAP TINGKAH LAKU KAMBING KACANG (Effect of feeding silage made of different ratio of kume grass and wild markisa leaves on feeding beahavior of male kacan

“…Namun pada kenyataannya lama makan tidak berbeda (P≥0,05) antara ternak yang mengkonsumsi silase dengan proporsi markisa hutan dan rumput kume yang berbeda. Hasil penelitian ini berbeda dengan hasil-hasil penelitian sebelumnya yang umumnya melaporkan penurunan lama makan ternak kambing dengan penurunan kandungan serat pakan (Pereira et al, 2020).…”
