Abstract

To determine the effect of additional protected protein and energy on intake and digestion in lambs, a trial was conducted using 36 young sheep (average body weight 24 .8 _+ 1 .7 kg) in a completely randomized design . Combination of three levels of protected protein (0, 10 and 20%, based on the dry matter of the concentrate offered) and three levels of protected energy (0, 5, 10%, based on the dry matter of the concentrate offered) were added into concentrate diet and fed to growing sheep. Results showed that different levels of feed additive did not affect (P>0 .05) intake of dry matter, organic matter, neutral detergent fiber, acid detergent fiber and metabolizable energy, with average of 76 .3 g, 68.9 g, 31 .2 g, 16 .79 g and 0.75 MJ /kg BW0.75 respectively . Level of protected protein gave significant (P<0 .05) respons on crude protein intake (7 .4 vs 8.7 vs 9.8 g/kg BW0.75) . Combination of protected protein and energy did not affect animal ability to digest the nutrient effectively. A mixtures of 20 % protected protein and 5 %energy addition into concentrate diet increased average daily gain (ADG) as much as 100 g. It was also found that for every gram ADG needs 42.2 kJ metabolizable energy .   Key words : Protein, protected energy, sheep

Abstract

Improving sheep productivity can be conducted by genetic improvement and improving environmental factors. Genetic improvement usually can be done by selection and creating composite or synthetic breed by crossbreeding. Composite breed created by crossbreeding between different breeds and followed by selection. The study of crossing between Sumatra sheep with fat-tail sheep from East Java, St . Croix hair sheep (US) and Barbados Blackbelly hair sheep has been carried out since 1986, and show that the crossbred are better in term of production and reproduction . In 1996/1997, the first generation (F1) of composite breed (KOM) has been created by crossing between Barbados Cross (BC) rams and St . Croix Cross (HC) ewes or reciprocally. The second generation (F2) of composite breed has been created by inter-se mating . However, F1-KOM and F2-KOM  vary in their performances, therefore selection should be conducted. The results showed that birth weight and weaning weight of crossing between BC rams and HC ewes tended to be heavier than those of reciprocal crossing between HC rams and BC ewes, but the differences were not significant (P>0 .05) . Birth weight and weaning weight of crossing between BC rams with HC ewes and reciprocal cross were 2.48 _+ 0.70 kg (n=791), 12 .50 _+ 3 .26 kg (n=640) and 2.37 _+ 0.62 kg (n=147), 12 .29 _+ 3.30kg (n=122), respectively . Meanwhile, observations of inter-se mating of Fl-KOM showed that the weight at the first mating was 26 .7 _+ 3.82 kg (n=80), age of dam at the first lambing was 15 .7 _+ 1 .73 months (n=83), weight at post-partum was 29 .86 _+ 3 .30 kg, and litter size at the first parity was 1 .43 _+ 0.59 (n=83) . The mean of age at the first mating of KOM was around 10 .7 months. Mean of mating weight at the second parity was 28 .29 +_ 3 .51 kg (n=11), age of dam at the  second lambing was 20.6 _+ 1 .99 month (n=11), post-partum weight was 26 .92 _+ 4.03 kg (n=11) and litter size was 1 .64 _+ 0.81 (n=11) . Weaning weight of Fl-KOM, F2-KOM, BC, HC and St. Croix (H) after adjusted by season, sex, age of dam and type of birth were significantly different among Fl-KOM with F2-KOM, BC, HC, and H. However, there were no significantly different among F2-KOM with BC and HC. The results of the study indicated that for improving selection respons, the corrections or adjustments of environmentally induced superiority (sex, type of birth and age of dam at lambing) for every genotype and certain generation should be conducted, in order to increase the rate of genetic improvement.   Key words : Composite breed, first generation, second generation

Abstract

The effect of feeding supplement and anthelmintic treatments on the establishment of parasites and the performances of lambs was studied in 24 St . Croix x Local Sumatra Crosses infected with Haemonchus contortus larvae (L3) . The study consisted of a 2 x 2 factorial arrangement involving two levels of supplement (1 .6% and 0.5% body weight ) and two levels of larval infection (0 and 3,000 L3 initial dose followed by a 1,000 L3-weekly dose) .The supplement x infection interaction was significant (P< 0.0001) on the egg counts and total serum proteins, but not on the PCV values (P>0.10) . The interaction was resulted from the shift in the magnitude of difference between supplement or between infection level and not by the shift in the rank between treatments . The 1 .6% body weight (BW) group had lower (P<0.0001) mean egg count than the 0.5% BW group (1,588 vs. 7,880) . Consistently, the blood PCV value and total serum proteins of lambs receiving 1 .6% BW supplement were higher (P<0.0001) than the 0.5% BW supplement group (28 .3 vs . 23 .8 and 5 .2 vs . 4.6, respectively) . Infection resulted in decreased feed and nitrogen (N) intake, but had no effect on fecal-N (P>0.0001). N-excretion (fecal-N + Urine-N) was not altered (P>0.10) by Haemonchus infection, but N-retention decreased in infected lambs due to a reduction in N intake . The effect of supplement and Haemonchus infection was significant (P<0.0001) on daily gain . Lambs on the 1 .6% BW supplement group grew faster than on the 0.5% BW supplement group whether they were infected or not . Infected lamb receiving 0.5% BW supplement lost weight during the experiment . It is concluded that an approach that combines the use of anthelmintics and supplement could ameliorate the influence of gastro-intestinal parasites on the performances of lambs, and reduces the intensity of using anthelmintics in controlling the parasites .   Key words : Supplement, anthelmintics, Haemonchus contortus, lambs
