CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior / Foram realizados cinco experimentos objetivando determinar o consumo e digestibilidade, desempenho e caracterÃsticas quantitativas da carcaÃa de ovinos alimentados com dietas
contendo subprodutos, com base na matÃria natural, (SPU), da banana (Musa sp.) desidratada (SPB), da manga (Mangifera indica) desidratada (SPM) e do urucum (Bixa orellana L.). No primeiro, segundo e terceiro experimentos foram avaliados os teores de matÃria seca (MS), matÃria orgÃnica (MO), proteÃna bruta (PB), fibra em detergente neutro (FDN), fibra em detergente Ãcido (FDA), hemicelulose (HCEL), lignina (LIG), nitrogÃnio insolÃvel em detergente neutro (NIDN), nitrogÃnio insolÃvel em detergente Ãcido (NIDA), carboidratos totais (CT), carboidratos nÃo fibrosos (CNF), os nutrientes digestÃveis totais (NDT) e fator de efetividade fÃsica da FDN. Ainda foram avaliados o consumo voluntÃrio, digestibilidade aparente da MS, PB, FDN, FDA, CHOT, CNF, NDT e balanÃo de nitrogÃnio (BN). No quarto e quinto experimentos foram avaliados os consumos de nutrientes em g/dia, % PV e g/kg0,75, ganho em peso e conversÃo alimentar. Como tambÃm foram avaliadas caracterÃsticas quantitativas da carcaÃa e anÃlise sensorial de dietas com adiÃÃo de 20% do SPB, com 30% do SPM e 40% do SPU. No primeiro experimento, a adiÃÃo do subproduto de banana (SPB) nÃo influenciou (P>0,05) o consumo de matÃria seca (MS) e matÃria orgÃnica (MO) quando expressos nas diferentes formas, obtendo-se valores mÃdios de 677,3 e 605,81 em g/dia, respectivamente. A adiÃÃo do SPB promoveu um aumento significativo (P<0,05) no CPB e CEE de 34,3 a 46,5 e de 10,63 a 59,9 g/dia e reduÃÃo de 3,07 unidades percentuais para o consumo de FDN. Com relaÃÃo aos coeficientes de digestibilidade da MS, PB, MO, EE, FDA e CHOT observou-se efeito negativo, excetuando, o CDFDN que nÃo foi influenciado (P>0,05) com adiÃÃo do SPB em substituiÃÃo ao feno. No segundo experimento, os consumos em g/dia de MS, MO, PB, EE, FDN e FDA apresentaram resposta quadrÃtica estimando-se consumos mÃximos de matÃria seca e matÃria orgÃnica de 36,11 e 37,8%, respectivamente, com a adiÃÃo do SPM. Contudo, nÃo houve diferenÃa (P>0,05) para a digestibilidade aparente dos nutrientes. Entretanto, a digestibilidade aparente da proteÃna bruta (CDPB) e o balanÃo de nitrogÃnio apresentaram comportamento quadrÃtico. No terceiro experimento, houve aumento nos consumos e dos nutrientes com adiÃÃo do subproduto do urucum (SPU), excetuando-se o consumo de EE que nÃo houve efeito (P>0,05). O comportamento linear positivo foi verificado para os coeficientes de digestibilidade (CD) da MS, MO e PB, jà para os CDEE, CDFDN, CDFDA e CDCHOT nÃo houve efeito (P>0,05) significativo. A adiÃÃo do SPU promoveu um balanÃo de N positivo. No quarto experimento, nÃo foram observadas diferenÃas significativas (P>0,05) entre os tratamentos para os consumos de matÃria seca em g/animal/dia. PorÃm, observou-se aumento para os consumos em %PV e g/kg0,75, para a dieta com adiÃÃo do SPU. Em relaÃÃo aos consumos de PB o SPB e SPM, apresentaram superioridade em relaÃÃo aos ovinos que receberam a dieta SPU. Para os CFDN nÃo foram observadas diferenÃas (P>0,05) entre as dietas nas diversas formas que foram expressas. O mesmo comportamento foi verificado com relaÃÃo ao ganho em peso, pesos de carcaÃa quente e fria e os respectivos rendimentos de carcaÃa quente e fria. Observaram-se valores mÃdios de RCQ e RCF respectivos de 46,05; 46,38; 46,54; 48,39% e 42,27; 45,67; 45,79; 47,72% para as dietas padrÃo (DP), SPB, SPM e SPU. Com relaÃÃo aos cortes comercias, houve efeito significativo (P<0,05) apenas para o lombo anterior em kg e para a paleta em % do PCF. Para a Ãrea de olho de lombo foram registrados valores respectivos de 8,28; 9,61; 1,38 e 10,82 para as dietas DP; SPB; SPM e SPU. No quinto experimento, relativo à dissecaÃÃo da perna dos ovinos, nÃo foi verificado efeito significativo (P>0,05) para a relaÃÃo M/O; M/G e para o Ãndice de musculosidade da perna (IM). Obtiveram-se valores para o IM de 0,79; 0,73; 0,81 e 0,82, respectivamente, para a DP; SPB; SPM e SPU. No sexto experimento, os atributos sensoriais da carne de ovinos apresentaram superioridade para o grau de dureza da carne dos ovinos alimentados com SPM e SPU. Menores suculÃncia e sabor ovino foram verificados, respectivamente, nas dietas SPM e SPB / Five experiments was conducted with
the objective of evaluating the consume and
digestibility, performance and quantitative characteristics of the lambs carcass fed with
diets containing by
-
products, with base in the natural matter
of the banana (
Musa sp
.),
(
BBP)
,
of the mango (
Mangifera ind
ica
) (
MBP)
,
of the annato (
Bixa orellana
) (
ABP)
.
i
n the first, second and third experiments were determination of dry matter
(
DM),
organic matter (OM), crude protein (CP), neutral detergent fiber
(
NDF
),
acid detergent
fiber (ADF), hemicellulose (HCEL), lig
nin (LIG), neutral detergent insoluble nitrogen

fibrous carbohydrates
(NFC),
total
digestible nutrients (TDN)
,
and factor of physical
effectiveness of FND.
They were still eval
uated the voluntary intake
and coefficients of
digestibility of DM, CP, NDF, ADF, CHOT, TDN, and nitrogen balance
(NB). In the
fourth and fifth experiments were evaluated the nutrients intake
in g/day
, %
BW and
g/kg
0,75
daily gain and alimentary conversion
. As well as they were evaluated
quantitative characteristic of the carcass and sensorial analysis of diets with addition
20% of BBP with 30% of MBP and 40% of ABP
.
In the first experiment
the addition of
the banana's by
-
product (BBP) it didn't influence (
P>0.05) the dry matter intake (DMI),
and organic matter (OMI
)
intake when expressed in the different forms
with
values of
677.3 and 605.

g/day
,
respectively
observed
.
The (BBP)
addition increased
(P
<0.
05) in crude protein intake (CPI) and ether extrac
t (EEI) intak
e from 34.3 to 46.5
and from 10.

units for the NDF intake.
Regarding the of digestibility coefficients of DM, CP DO, EE, ADF and TC
was
observed negative effect (P<0.
05)
, excepting, CDNDF that i
t was not influenced
(P>0.05) with addition of BBP
.
In second experiment the day of DM,

,
re
spectively
of addition of
mango by
-
product (MBP). However there was not difference (P
>0.05)
for the apparent
digestibility of the nutrients, except the apparent digestibility of the crude protein
(DCCP) the addition of (MBP)
quadratic
behavior observed. In third experiment
annatto
by product (ABP) addition increased
(P <0.05) in nutrients intake
,
excepted the
EE
intake
was not effect
significant
(P>0.
05)
the addition anatto by product (ABP
)
with
values in the 11.5 and 0.
05 g/day e % BW

The
linear
ly
behavior was verified for the
di
gestibility coefficients (DC) of DM
,
DO
and CP, already for CDEE, CNDF, CDANF
XIX
and CDCHOT
didn't have effect (P>0.
05).
The anatto by
-
product (ABP
)
addition
promoted a positive balance of
N
.
In the fourth experiment significant differences were
not observed
(P>0.05) among the treatments for the dry matter intake in g/
day
.
However, increase was observed for the % PV and g/kg
0.75
intake
for the diet with
addition of
annato by
-
product, banana by
-
product and mango by
product
.
The intake of
CP by
-
product of mango
and banana ́s by
-
product (BBP) presented superiority in
relation to the
lambs that received the other diets.
For the
EE
intake BBP it was
observed
higher
values the other diets
and NDF intake it was not observed differences
(P>0.05) among the diets in the s
everal forms that were expressed
.
The same behavior
was verified regarding the weight
gain
,
hot carcass
weight (HCW) and
cold carcass
(CC
W
) and the respective yield of hot and cold carcass. The values of
hot carcass
yield
and
cold carcass (CC)
were
46.05;
46.38; 46.54; 48.
39% and 42

for the diets (PD), BBP, MBP
a
nd ABP respectively
.
In respect to the cuts trade
there was effect significant (P <0
.
05) just for the anterior loin in kg and for the
shoulder
% WCC
. For
loin eye

BBP;
MBP;
ABP. In the fifth experiment with the dissection of
the leg of the lambs significant effect was not verified (P>0
.
05) for the accounting M/O;
M/G and for the index of
muscularity of the leg (MI
) that obtained values of 0.79; 0.73;
0.81; 0.
82 for PD; BBP;
MBP; MBP in the sixth experiment the attributes sensorial of
the lambs meat presented superiority for the degree of hardness of the meat of the lambs
fed with
MBP
and
MBP. To smallest succulency and the smallest flavor lambs they
were verified in the diets MBP and BBP respectively.
