Citrus pulp in lamb diets: intake, digestibility, and ruminal parameters

Abstract

<p>This study aimed to evaluate the viability of replacing corn meal with citrus pulp (0, 25, 50, 75, and 100 % dry matter of corn meal) by evaluating several nutritional parameters such as intake and digestibility of nutrients, and ruminal fermentation parameters. The diets were formulated to be isoproteic with a roughage:concentrate ratio of 60:40. Five crossbred lambs with an initial average weight of 26.1 ± 1.8 kg were used and distributed in a 5 x 5 Latin Square design. For digestibility of nutrients was carried out to feed, orts, and feces collection. The evaluated nutrients were dry matter, crude protein, ether extract, ash, neutral detergent fiber, fiber acid detergent and lignin. Were determined nitrogen and carbohydrate fractions, and ruminal fermentation parameters (N-NH 3 and ruminal pH). The results were subjected to analysis of variance and regression analysis (t-test; ? = 0.05). Citrus pulp inclusion in the diets did not affect intake and digestibility of nutrients, or the pH and the NH3-N content of the rumen fluid. Citrus pulp can be used as a total substitute for corn in concentrate or up to 26.5% in the total ration for lambs (dry basis). </p>

The Effects of Replacement of Dried Orange Pulp with Ground Corn in Concentrate Feed on Dairy Goats’ Performance, Milk Somatic Cell Counts and Blood Parameters

“…It has also been reported by previous researchers that the use of citrus pulp in the diets of dairy animals does not significantly affect milk yield (Belibasakis and Tsirgogianni, 1996;Volanis et al, 2004). On the other hand, Peixoto et al (2015) reported that the use of citrus pulp did not affect volatile fatty acids production or other rumen dynamics. In this case, it is thought that volatile fatty acids, which play an active role in shaping milk yield, are not sufficiently released in the rumen and sufficient resources cannot be sent to the liver to raise blood glucose levels.…”
