Previous issue date: 2014-02-28 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior - CAPES / O objetivo do presente trabalho foi avaliar o efeito da utiliza??o de cact?ceas nativas e ex?ticas ao n?vel de 50% na MS de inclus?o na dieta total, sobre o consumo de nutrientes, ingest?o de ?gua, produ??o e composi??o f?sico-qu?mica do leite, com cabras em lacta??o. Foram utilizadas 5 cabras Saanen plur?paras (50?4 kg) alocadas em quadrado latino de acordo com cact?ceas fornecidas nas dietas, constando de cinco per?odos de 17 dias, sendo 10 dias de adapta??o e 7 para coleta de dados, cinco tratamentos com as seguintes cact?ceas: xiquexique, mandacaru, facheiro, palma mi?da e palma orelha de elefante mexicana. O consumo de mat?ria seca variou de 1.967,58 a 2.602,46 (g/dia) entre as cact?ceas e teve uma m?dia de 2.251,84 (g/dia). Observou-se que o consumo de mat?ria seca CMS (g/kg0,75) variou de 102,75 ? 136,78 entre as cact?ceas estudadas. O consumo de mat?ria seca (%PV) variou de 3,84 ? 5,11 com m?dia de 4,47. A produ??o de leite em (g/dia) variou de 1.692,60 a 2.090,40. O consumo de ?gua oferecida variou entre 4.549g (xiquexique) a 8.749 (palma mi?da). As cabras alimentadas com palma mi?da apresentaram-se com as maiores produ??es de leite (g/dia) com valores m?dio de 2.091. N?o houve diferen?a na composi??o f?sico-qu?mica do leite estando os teores de gordura, prote?na bruta, lactose e s?lidos totais a cima do m?nimo permitido pela legisla??o para leite de cabra no Brasil. A utiliza??o de cact?ceas ao n?vel de 50% MS na inclus?o da dieta total proporcionou consumo de nutrientes suficientes para atender as exig?ncias dos animais para a produ??o de leite sem alterar a sua composi??o f?sico-qu?mica. / The objective of this research was to evaluate the production of dairy goats
fed different species of cactus. Pluriparous five Saanen goats were used, with nine
weeks of lactation, and average live weight of 50 kg ? 4 kg. The animals were
distributed in latin square design (5x5) with 5 diets and 5 periods. No differences
(P>0,05) were observed in the DM of the experimental diets by getting average values
of 2.251,84 g dia-1
, 4,46 %PV e 118,91g kg0,75
. The DM contents of the diets were 50,55
to 55,92% by presenting a maximum variation of 10% between them. A significant
difference (P<0,05) water consumption way tendered, between diets with different
cactus species. The treatments cactus ?Orelha de Elefante Mexicana? and Facheiro had
lower water consumption compared to cactus ?Palma Mi?da. For milk yield no
significant difference (P> 0,05) between diets formulated with cactus species, with an
average of 1,90 kg/day treatments. The analysis of variance show a significant
difference (P<0,05) among treatments for milk corrected to 4% fat and fat production.
There was an effect (P<0,05) of the diets with different cactus on the crude protein (CP)
and lactose in milk. All treatments with different cactus species can be used for dairy
goats in view consumption have afforded sufficient to meet the nutritional requirements
for milk nutrients, besides presenting the higher than levels of physical and chemical
composition to minimum levels established by current legislation
