Engorda de bovinos zebus sem administração de cloreto de sódio.
Resumo

Verificou-se a influência da adrninistraçao do cloreto de sódio, na engorda de bovinos zebus em regime de pasto..Adotou-se delineamento experimental em blocos casualizados em número de 5, com 2 tratamentos e 2 repetições dentro tios blocos, perfazendo 1 repetições, por tratamento.O lote “A” que recebeu NaC1 à vontade, ganhou no fim de 216 dias de experimento, 1.587 kg e o lote 4B’, sem NaC1, 1.650 k, sem diferença estatística significante entre os tratamento e blocos ao nível de 5%. Admitiu-se, como provável, que os animais teriam recebido a quantidade de sal suficiente através da ingestão de capim, água e terra.


Fattening of zebus whithout administration of sodium chloride.
Abstract
Ten castrated male zebus of the Nellore race were fattened on pastures of Panicum maximum without administration of NaCl (commercial common salt) while ten other male zebus of the same race that had free access to Sodium Chloride were taken as witnesses. During this period the animals of the witness group consumed on the average 36.5 g per head/day.In the animals of the B lot, as symptorns of deficiency, a marked desire for Sodium Chloride and a depravation of the appetite were observed. The anmals showed avidity for urine and also licked the posts of the fences. The weight gains, meanwhile, were normal and there was no significante statistical diference between the two lots.In a anterior work, LMAI and coil. (5). ascertained in growing zebu heifers put to graze on Panicum maximum for the 29 months that the administration of Sodium Chioride díd not leave any influence on the weight gain. The same fact now occurs with castrated male animals in the course of fattening.Flowerer, as the animals had received salt before the experiment it did not become clear that the administration of Sodium Chioride was completely unnecessary for bovine put lo graze on Panicum maximum ou the red land of Ribeirão Preto (Latosolic B Terra Roxa). They may also have received, besides, Sodium Chloríde from the grass (0.21% of chlorides) and from the water (0.03 1 g/1.000 ml of chlorides in general) consumed.
