Water with different salinity levels for lactating goats

Abstract: The aim of this study was to evaluate the influence of supplying water with varying salinity levels to dairy goats on nutrient intake, apparent nutrient digestibility, and milk yield. The experiment lasted 65 days and involved 24 crossbred goats with mean body weight of 38±4 kg, which were randomly allotted. It was set in a completely randomized design with four treatments consisting of 640, 3188, 5740 and 8326 mg L -1 total dissolved solids (TDS) in the drinking water. The results showed that water salinity l… Show more

“…Large differences in salinity tolerance between animal species or between breeds within species are observed, and it seems that sheep and goats are more tolerant to salt stress than cattle when adapted, and that goats have a slight tolerance advantage over sheep (Dunson, 1974;McGregor, 2004;Squires, 2016). Goats are able to cope without any detrimental effect on digestibility up to levels of 8326 mg TDS (total dissolved solutes) in water (Paiva et al, 2017) but, as in heifers, rumen function and cell wall digestibility decreases with an increase in TDS (Alves et al, 2017).…”

“…Water salinity is frequently studied through the addition of NaCl to fresh water. In this regard, Paiva et al (2017) conducted a study with multiparous crossbred goats of unspecified breeds in Brazil. Based on study initiation at 30 DIM, a trial length of 65 days, average milk yield of less than 2 kg/day, and initial BW of 38 kg, presumably the level of a breed highly selected for milk production was not more than 50%.…”

“…Resultados semelhantes aos encontrados nesta pesquisa, para a variável gordura do leite, foram relatados Salvador et al 2016 2014, analisando a qualidade do leite de cabras Saanen, Parda Alpina e Boer, citam valores para o teor de gordura no leite, inferiores aos encontrados neste estudo, o que pode ser justificado pela maior quantidade de concentrado e quantidade inferior de volumoso utilizada nas dietas, assim como pelo fato que algumas raças se caracterizam pela alta produção de leite com baixo teor de gordura como a raça Saanen (PAIVA et al, 2017).…”

“…Caprinos com genótipos especializados para produção leiteira utilizados no semiárido nordestino, geralmente são animais originários de clima temperado, como as raças alpinas e seus mestiços (SILVA et al, 2015), caracterizados por serem animais dóceis e adaptados ao clima tropical, conseguindo expressar sua capacidade produtiva, porém quando inseridos em situação de estresse térmico, como ocorre no período de estiagem no semiárido nordestino, recorrem a ajustes fisiológicos de termorregulação, como elevações nas frequências respiratória e cardíaca, assim como temperaturas retal e superficial, além de alterações no comportamento ingestivo, uma vez que diminuem o consumo de nutrientes e elevam a ingestão de água o que pode acarretar em menor produção e qualidade do leite (PAIVA et al, 2017;CARNEIRO et al, 2016).…”
