ANALYSIS OF LOCAL DATA ON ANIMALS<br />
PERFORMANCE USING BLUP MIXED MODELS*<br />
O. L. Bondoc, Assistant Professor, IAS-CA, UPLB<br />
The uses of Best Linear Unbiased Prediction (BLUP)<br />
mixed models in the analysis of performance data of goats,<br />
cattle, and water buffalo under Philippine conditions is<br />
presented. The fundamental of the BLUP procedure, its<br />
computation, uses and relevance to the local livestock<br />
industry, and similarities with the selection index are<br />
highlighted. Results of the local BLUP analyses were<br />
also summarized and compared in terms of data sizes,<br />
assumptions and composition of linear models, type and<br />
implication of output and/or solutions. Finally,<br />
recommendation to institutionalize advance and optimized<br />
(i.e. faster, more accurate, and cheaper) BLUP evaluation<br />
in national breeding programs for livestock are given.<br />

DEVELOPMENT OF A NATIONAL RECORDING<br />
SYSTEM FOR CARABAOS*<br />
O. L. Bondoc, Assistant Professor, IAS-CA, UPLB<br />
Animal’s performance recording system for the PCC will<br />
be required to improve the carabao’s individual<br />
performance, farm/herd productivity, and the national<br />
breeding base. Following the proposed dispersed nucleus<br />
breeding scheme, a standardized recording, testing/<br />
computing, and selection program will initially be<br />
concentrated among the PCC network centers. At the end<br />
of the seminar-workshop, a national recording system for<br />
carabaos will be developed to include, among others; (1)<br />
standardized collection of animals performance records of<br />
breeding animals and their pedigree on a continuous basis,<br />
(2) Genetic evaluation using the best statistical methods for<br />
predicting breeding values in order to rank individuals, (3)<br />

ANIMAL BREEDING IN CROP-LIVESTOCK FARMING<br />
SYSTEM*<br />
O. L. Bondoc, Assistant Professor, IAS-CA, UPLB<br />
This paper features the relevance and uses of the principles<br />
of animals breeding in order to improve productivity of the<br />
livestock component in traditional crop-livestock farming<br />
systems. In general, animal breeding strategies can be<br />
used to improved quantity (i.e. through better reproduction)<br />
and quality (i.e. genetic improvement) of breeding stocks<br />
of cattle and water buffaloes being raised by smallholder<br />
farmers. Problems peculiar to such production system<br />
were identified and include the following: lack of record<br />
animal performance, small population size and their<br />
scattered distribution, inherently low reproductive rates,<br />
and low success rates of artificial breeding in farmers fields<br />
such as artificial insemination (AI), estrus synchronization<br />
(ES), pregnancy diagnosis (PD) and embryo transfer<br />
(MOET). In this regards, the establishment of nucleus or<br />
cooperative breeding schemes to effect genetic improvement<br />
and disseminate/share improved animals performance is<br />
recommended.<br />
Keywords: animals breeding strategies, cattle, water<br />
buffalo<br />
