The aim of this study was to evaluate the influence of some environmental effects on the litter size, using 526 records of kidding of dairy crossbreed goats. The statistical analyses were carried out through generalized linear models, using a binomial distribution function and the logistic link function. The probabilities of occurrence of multiple kidding were calculated by a model that included the effects of year and month of mating, order of kidding, age at first kidding, weight at mating, milk […]

The effects of month, year, order and type parturition on mating weight (MW), weight gain during gestation (WG), respectively, of 753 and 527 Caninde native goats, 463 and 333 exotic Anglo Nubian and 374 and 296 Alpine goats, 151 and 87 crossbred ½ Alpine ½ SRD, and 92 and 73 ¾Alpine ¼SRD goats, raised in the Experimental Station of the Governmental Research Institute (EMEPA-PB), Soledade – Paraiba – Brazil, in the period from 1980 to 1994. The effect of month […]
