(Taylor & Francis Group, 1994-02-01)Degradation of intact glucosinolates or their transformation into other products and glucosinolate absorption from the gastrointestinal tract were investigated by in vivo and in vitro experiments with rats. The absorption ...
-
(Taylor & Francis Group, 1992-11-01)The use of derivative-free methods to give maximum likelihood estimates of bivariate (co)variance parameters is illustrated. An algorithm is given to estimate the four variance and two covariance parameters of two random ...
-
(Taylor & Francis Group, 1992-05-01)The appropriateness of the current adjustment factors for weaning weight was studied on data from the Swedish Sheep Recording Scheme for the years 1981–83 and 1986–88. The study included the four main breed groups Swedish ...
-
(Taylor & Francis Group, 1992-11-01)Multivariate REML analysis was used to treat the results of a selection experiment for lean tissue growth rate that included 393 purebred Swedish Yorkshire gilts. Heritabilities were estimated to be 0.51, 0.33, 0.45 and ...
-
(Taylor & Francis Group, 1992-08-01)The relationships between scores for general appearance assessed in August and November and the size and quality of scanblack and pastel male pelts were studied. The size of pelt was more closely associated with general ...
-
(Taylor & Francis Group, 1993-05-01)The relationships between 12 polymorphic systems and bull fertility were studied in the Swedish Red and White dairy cattle population. The material consisted of 1447 young bulls with non-return rates based on at least 500 ...
-
(Taylor & Francis Group, 1995-08-01)In two experiments, a total of 4346 laying hens housed in battery cages, with three hens per cage (C), and in two aviary systems, both with tiered wire floors and litter (Lövsta with two tiers (L) and Marielund with three ...
-
(Taylor & Francis Group, 1994-11-01)A method for analyzing traits influenced by both maternal and direct genetic effects is presented in a Bayesian setting. A Bayesian analysis requires full marginalization of the joint posterior density. The necessary ...
-
(Taylor & Francis Group, 1995-05-01)The objective was to examine behavioural and physiological reactions of cows in pens with slatted floors, when pretreatment was tethering in stalls. Ten cows were kept tethered (C), whereas 10 other cows were kept loose ...

-
(Taylor & Francis Group, 1995-05-01)Red Danish (RD), Danish Friesian (DF), Danish Red and White (RW) and Danish Jersey (DJ) heifers had ad libitum access to total mixed rations designed to promote low (L), medium (M) or high (H) growth rate from 6 weeks of ...
-
(Taylor & Francis Group, 1994-05-01)Class I bovine lymphocyte antigens (BoLA) were typed in Norwegian Cattle (NRF) breeding bulls over a twelve-year period, together with a recent one-year batch of young bulls. Significant increases in the frequency of BoLA ...
-
(Taylor & Francis Group, 1995-02-01)Nutrient digestibilities were evaluated in comparative experiments with blue foxes and mink by using six diets differing in fat:carbohydrate (F:C) ratios. In mink, apparent digestibilities of N and amino acids decreased ...
-
(Taylor & Francis Group, 1996-05-01)The preferences of juvenile farmed silver foxes (n = 14) and blue foxes (n = 12) for an empty cage (105L × 115W × 70H cm) and a cage of equal size with a wooden nest box were assessed in an 11-day preference test. The ...
-
(Taylor & Francis Group, 1993-11-01)In 1989, 1990 and 1991 five-week-old female broilers were X-rayed in a computer tomograph (scanned), and then dissected. The broilers were scanned alive in two different positions; one cutting through the anterior end of ...
-
(Taylor & Francis Group, 1996-05-01)Full-scale experiments with cooling of raw milk of good initial quality from a herd of 70 dairy cows have been performed under practical farm conditions, with different cooling and storage conditions, including instant ...
-
(Taylor & Francis Group, 1996-02-01)The phosphohydrolase activity of small intestinal mucosa was investigated in vitro in the pig. The activity was studied using four different enzyme substrates at physiological pH levels actual in the duodenum-jejunum part ...

-
(Taylor & Francis Group, 1993-02-01)A total of 13 979 Norwegian trotters were born in Norway and registered in the Norwegian Trotting Association between 1972 and 1987. The generation intervals between sire and son (n = 333) and sire and daughter (n = 4366) ...
-
(Taylor & Francis Group, 1995-11-01)Stochastic simulation was used to assess the suitability of alternative dependent variables in international sire evaluation. Three such variables were considered: daughter yield deviations (DYD), national proofs (ETA), ...
