| dc.description.abstract | Excellent protein quality is absolutely required and plays an important
role in the reproduction process, particularly in improving the quality of sperm for
supporting the prolific nature of Garut rams. Maggot Hermetia illucens (Maggot
Black Soldier Fly, MBSF) is an alternative protein source besides soybean meal
(SBM) which have used as a feed. The aims of this study were to analyzed and
compare the impact of different protein sources in feed on semen quality of Garut
rams, and to assess the potential integration of these feeds into the small-scale
breeders of West Java, Indonesia.
These experiments consist of two phases; laboratory phase and breeding
farms survey phase. The first phase of this study was conducted using a
completely randomized design with 3 treatments and 4 replications. Treatment on
this study was Brachiaria humidicola (BH) grass and T1 (concentrate contains
20% of SBM), T2 (concentrate contains 10% of SBM and 10% of MBSF), and T3
(concentrate contains 20% of MBSF). The parameters were feed consumption,
semen quality (macroscopic and microscopic characteristics), also a potential
ability of rams to serve females. The second phase was conducted in Garut, West
Java, Indonesia as the concentration region of Garut rams, and assessing smallscale
breeders who were potentially able to extend the feeding practical with
MBSF, using a questionnaire as guidance.
The first results showed there was no significant effect of the feeds (P>0.05)
on protein nutrient consumption, semen volume, semen pH, semen color and
consistency, sperm mass movement, sperm motility, sperm concentration, total
number sperm per ejaculate, sperm morphology, sperm viability, sperm plasma
membrane integrity and potential ability to serve females. However, the result
showed a significant effect (P<0.05) on sperm viability and sperm membrane
integrity. Sperm plasma membrane integrity of ram feed with T3 was better than
T1 and T2. The potential ability rams to serve ewes on MBSF treatment was 38
heads, while in T1 and T2 were 43 and 57 heads respectively.
The second results of the breeding farms survey explained there are two
types of groups that are able to develop maggot BSF as feed based on indicators,
i.e. income per month, experience, educational level, and numbers of animals.
There are five categories of breeders who can apply MBSF on their farms but
only four farmers from two categories were expected to be able to intergrate
MBSF into their systems. The conclusion of our overall study is MBSF can be an
alternative source of protein, besides soybean meal to improve the semen quality
thus supporting the prolific properties of Garut rams. | id |
