Feeding behavior of lambs fed diets containing peach palm meal

Abstract

The aim of this study was to evaluate the feeding behavior of lambs fed diets containing peach palm meal replacing maize (0, 10, 40, 60, and 85% DM). Thirty Santa Inês sheep with an average initial body weight of 21.6 ± 0.87 kg were distributed in a completely randomized design with five diets and six replicates. Feeding time in min kg -1 DM and min kg -1 NDFap increased by 34 min and 99.6 min, respectively, with each level of substitution of maize for the peach palm meal. Rumination and chewing times, in min kg -1 DM and min kg -1 NDF, also increased in response to the substitution of maize for peach palm meal. When expressed in min day -1 , rumination and chewing activities decreased by 12.4 and 14.6 min, respectively, as the amount of peach palm meal in the concentrate was increased. The time spent idle increased linearly (P<0.05), by 14.6 min day -1 , with the replacement levels, compared with the control diet. Peach palm meal in the composition of sheep diets reduces the intakes of dry matter and fiber and decreases the feed and rumination efficiencies. Replacing maize by peach palm meal increases the feeding time and rumination and chewing activities of feedlot lambs. Key words: Feed. Ethology. Idle. Rumination. ResumoObjetivou-se avaliar o consumo de matéria seca, de fibra e o comportamento ingestivo de cordeiros alimentados com dietas contendo farinha de pupunha em substituição ao milho (0, 10, 40, 60 e 85% da MS do concentrado). Foram utilizados 30 cordeiros, da raça Santa Inês, machos, não castrados, com peso corporal médio inicial de 21,6 ± 0,87 kg, distribuídos em delineamento inteiramente casualizado, com cinco dietas e seis repetições. Os tempos de alimentação em min kg -1 de matéria seca (MS) e min kg -1de fibra em detergente neutro corrigida para cinza e proteína (FDNcp) apresentaram, respectivamente, incrementos de 34 minutos e 99,6 minutos para cada nível de substituição do milho pela farinha de pupunha. Assim como os tempos de ruminação e mastigação, em min kg -1 de MS e min kg -1 de FDNcp

Feeding behavior of goat kids fed diets containing peach palm meal

“…Another inference is the high concentrate content associated with the increase of the fat content of diets containing the peach palm meal levels (Tables 1 and 2), which may have inhibited the action of microorganisms that degrade the fiber and thus compromise the digestibility and the rate of passage (Santos et al, 2016b).…”

“…The heart-of-palm industry directs part of the cultivation area to the production of fruit for extraction of seeds. Hence, the pulp is a waste that could be used for the production of peach palm meal as alternative feedstuff for ruminants (Santos et al, 2016b).…”

“…In view of the results described for DMI, there was higher acceptability by the animals of the diet without peach palm meal, indicating that there was feed selection with the rejection of the peach palm meal by the lambs. It is possible that the increase in the total unsaturated fatty acid contents with the replacement of maize by peach palm meal affected the palatability, due to possible rancidification of the peach palm meal [5,6,47] and the presence of phenolic compounds [16,48,49].…”

“…However, peach palm meal was found to have low palatability owing to the bitter taste of phenolic compounds and/or rancidness of the rich-unsaturated fatty acid lipid fraction, with consequences for the feed consumption and intake behavior [1][2][3][4][5][6].…”
