Nutritive Value of Dried Citrus Pulp and Its Effect on Milk Yield and Milk Composition of Lactating Ewes

Abstract

In a digestibility experiment, six adult wethers of the Karagouniko breed were used to determine the nutritive value of dried citrus pulp. The rations consisted of 800 g of hay and 75, 150, 225, 300, 375, and 450 g of citrus pulp. The apparent digestibilities of the DM, OM, CP, ether extract, crude fiber, and N-free extract for dried citrus pulp were 78.6, 87.2, 52.7, 82.0, 93.2, and 83.1%, respectively. Energy content was estimated to be 1.66 Mcal of NE(L)/kg of DM. In a second experiment, 26 lactating ewes of the Karagouniko breed were used to study the nutrient utilization of dried citrus pulp for milk yield when citrus pulp was used as a replacement for cereal grains. The ewes were divided into two groups immediately postweaning and fed daily 700 g of alfalfa hay, 300 g of wheat straw, and 580 or 550 g of concentrates with or without 30% citrus pulp, respectively. The inclusion of citrus pulp in rations for ewes had no significant effect on milk yield and composition but decreased the C4 to C10 fatty acids. Citrus pulp is a valuable, high energy by-product that can partly replace cereal grains in sheep rations without adverse effect on milk yield or composition.

<b>Assessing the nutritional value of agroindustrial co-products and feed through chemical composition, <i>in vitro</i> digestibility, and gas production technique

“…The lowest values of DIVDM were found for samples of cassava foliage, grape residue and cottonseed (53.17, 51.24 and 49.52%, respectively). The observed value for DIVDM of the pelleted citrus pulp differed from that found by Fegeros, Zervas, Stamouli, and Apostolaki (1995) of 78.6%. The nutrient content in the pelleted citrus pulp can be influenced by a number of factors, including fruit (orange and etc), seed quantity and type of processing (Silva, Souza, Silva Neta, Inácio, & Muniz, 2013).…”

Efeito da fibra de coprodutos agroindustriais e sua avaliação nutricional para coelhos

“…Visando à comercialização desse ingrediente, a indústria promove a desidratação do material e consequente peletização (Giardini, 1994). Por possuir alta quantidade de carboidratos solúveis e fibra, é considerado alimento intermediário entre volumoso e concentrado (Fegeros et al, 1995). A polpa de cítrus, seca e peletizada, contém aproximadamente 6% de PB, 11% de fibra bruta e 70 a 75% de nutrientes digestíveis totais e, segundo Hall (2000), pode conter mais de 20% de sua MS composta por açúcares simples, sendo este teor variável de acordo com a espécie e o cultivar de cítrus que a originam.…”

Using of Citrus By-products in Farm Animals Feeding

“…17 The nutritional value of citrus pulp is high owing to its high content of readily fermentable carbohydrates. The protein content is modest, and of low digestibility and biological value 18 because citrus pulp has high moisture content (80%) and it is bulky and therefore, it is difficult to store or transport it. It is rich in readily fermentable substrates such as sugars, non-starch polysaccharides and organic acids but poor in nitrogen.…”
