The study was conducted in a mountainous zone, of intermediate temperature, in the north central part of Colombia. The adjusted average calving interval of 320 observations was 454.1 days and the date of conception averaged about 5.5 months after the date of parturition. Analysis of variance demostrated that effects asociated with location in the Experimental farm and age of dam were statistically significant at 1 and 5% level of probability, respectively. Season of calving approached significance. The other sources of variation (year of calving, sex of calf and interaction of year and season) did not show significance. Cows calving in the higher part of the farm (1.200 metres) had calving intervals 31 days larger than cows calving in the lower part (800 metres). Cows of less than 3 years had the largest calving interval and cows of 7 to 8 years of age had the shortest calving interval. The difference between the two groups was 69.5 days. In general, old cows had shorter intervals than young cows. The best season of calving in relation with fertility of cows was from January to March, the driest season of the year. The correlation of rainfall during season of calving with interval to the next parturition was 0.659 (P ( .01). Se estudiaron los factores ambientales que afectan el intervalo entre partos del ganado Blanco Orejinegro, en una zona montañosa de clima medio del noroeste de Colombia. El promedio ajustado de los 320 datos analizados fue de 454,1 días y la concepción ocurrió en promedio 5,5 meses después del parto. Los efectos asociados con localización dentro del Centro Experimental y edad de la vaca fueron estadísticamente significativos (P 0,01 y P ( 0,05, respectivamente). La época de parto se aproximó al límite de significancia. Las demás fueron de variación (ano de parto, sexo de La cría e interacción de año por época) no mostraron significancia. Las vacas de La parte alta del Centro Experimental (1200 metros) tuvieron intervalos entre partos 31 días más largos que las de la parte baja (800 metros). Las vacas con intervalos entre partos más largos fueron las menores de 3 años y las de intervalos más cortos las de 7 a 8 años. La diferencia entre los 2 grupos fu de 69,5 días. En general las vacas viejas tuvieron intervalos más cortos que las jóvenes. La mejor época de nacimiento del ternero en relación con la fertilidad de las vacas fué la de enero a marzo, ci periodo más seco del año. La correlación entre la lluvia caída en la época del parto y el intervalo entre partos fué de 0,658 (p (0,01).

| description |
The purpose of the study was to evaluate the influence
of the environmental factors on calving interval
of Blanco Orejinegro cattle. The study was conducted
in a mountainous zone, of intermediate
temperature, in the north central part of Colombia.
The adjusted average calving interval of 320 observations
was 454.1 days and the date of conception
averaged about 5.5 months after the date of parturition.
Analysis of variance demostrated that effects
asociated with location in the Experimental farm and
age of dam were statistically significant at 1 and 5%
level of probability, respectively. Season of calving
approached significance. The other sources of variation
(year of calving, sex of calf and interaction of year
and season) did not show significance.
Cows calving in the higher part of the farm (1.200
metres) had calving intervals 31 days larger than cows
calving in the lower part (800 metres). Cows of less
than 3 years had the largest calving interval and cows
of 7 to 8 years of age had the shortest calving interval.
The difference between the two groups was 69.5 days.
In general, old cows had shorter intervals than young
cows. The best season of calving in relation with
fertility of cows was from January to March, the
driest season of the year. The correlation of rainfall
during season of calving with interval to the next
parturition was 0.659 (P ( .01). |
