Scand. Sect. A Anim. Sci. (IF 0.9) Pub Date : 2021-03-18 Åshild T. Randby, Laila Aass, Anna Haug
ABSTRACT The study investigated the effect of plant maturity of grass silage on intramuscular fat (IMF) concentration and fatty acid profile in M. longissimus thoracis of bulls. From 7 to 8 months of age until slaughter, 36 bulls of Norwegian Red were offered grass silage harvested at three maturity stages ad libitum, with or without concentrate supplement. Increasing plant maturity decreased the proportion

Evaluation of chemical composition and in vitro digestibility of stovers of different pearl millet varieties and their effect on the performance of sheep in the West African Sahel Acta Agric. Scand. Sect. A Anim. Sci. (IF 0.9) Pub Date : 2021-04-30 Clarisse Umutoni, Vincent Bado, Anthony Whitbread, Augustine Ayantunde, Prakash Gangashetty
ABSTRACT The objective of this study was to assess the chemical composition and in vitro digestibility of residues of five pearl millet varieties and to investigate their effect on the performance of sheep. Thirty castrated male Bali-Bali sheep were randomly assigned to five treatments. Four dual-purpose millet varieties and one local variety-Somno were used. Sheep were fed ad libitum for 90 days with

Effect of graded levels of red grape pomace (Vitis vinifera L.) powder on physiological and meat quality responses of Japanese quail Acta Agric. Scand. Sect. A Anim. Sci. (IF 0.9) Pub Date : 2021-05-12 C. M. Mnisi, V. Mlambo, C. Kumanda, A. Crafford
ABSTRACT This study evaluated the effect of dietary red grape pomace (RGP) powder on physiological and meat quality responses of Japanese quail. Three hundred quail birds were randomly distributed to five dietary treatments formulated as follows: a negative control diet without antibiotics (NegCon); a positive control diet with antibiotics (PosCon); NegCon diluted with RGP at a rate of 1.5% (RGP15)

Objective carcass grading for bovine animals based on carcass length Acta Agric. Scand. Sect. A Anim. Sci. (IF 0.9) Pub Date : 2021-03-31 Andrew Heggli, Lars Erik Gangsei, Morten Røe, Ole Alvseike, Hilde Vinje
ABSTRACT The aim of the study was to evaluate performance for beef carcass grading using a novel semi-automatic method compared to human classifiers. The novelty was measuring carcass length as a predictor. The grading is given as conformation and fat cover as defined by the EUROP classification system. A training set was used to fit the model with predictors based on weight, age, breed and sex, in

Evaluation of live-body weight and the number of eggs produced for introduced and local chickens in Ethiopia Acta Agric. Scand. Sect. A Anim. Sci. (IF 0.9) Pub Date : 2021-02-25 Setegn W. Alemu, Olivier Hanotte, Fasil G. Kebede, Wondmeneh Esatu, Solomon Abegaz, Jasmine E. Bruno, Biazen Abrar, Tesfahun Alemayehu, Raphael Mrode, Tadelle Dessie
ABSTRACT Ethiopia’s 60 million chickens are reared primarily in free range, smallholder systems. Therefore, upgrading smallholder poultry to small-scale commercial systems is central to rural development. With the aim of providing access to improved chicken by rural farmers in Ethiopia, the live body weight at week 17 and number of eggs per bird per week for one locally improved and three tropically

The preference for water nipples vs. water bowls in pregnant ewes Acta Agric. Scand. Sect. A Anim. Sci. (IF 0.9) Pub Date : 2021-02-23 Knut Egil Bøe, Ingjerd Dønnem, Cecilie Blakstad Løkken, Stine Grønmo Kischel
ABSTRACT This study included 6 groups of 6 pregnant ewes with a change-over design. In period 1 group 1, 2 and 3 had access to the water nipples and group 4, 5 and 6 had access to water bowls and vice versa in period 2. In period 3 all six groups had access to both types of water dispensers. The ewes’ water intake was significantly higher when drinking only from water nipples (3.27 ± 0.29 l/ewe and

Conservation of a native dairy cattle breed through terminal crossbreeding with commercial dairy breeds Acta Agric. Scand. Sect. A Anim. Sci. (IF 0.9) Pub Date : 2021-01-13 J. B. Clasen, M. Kargo, W.F. Fikse, E. Strandberg, A. Wallenbeck, S. Østergaard, L. Rydhmer
ABSTRACT Farmers play a key role in conserving native livestock breeds, but without economic support, farms with native breeds may not be viable. We hypothesized that terminal crossbreeding can improve herd economy and decrease the economic support needed from society. Three scenarios were simulated using SimHerd Crossbred: a herd of purebred Swedish Polled Cattle, a herd of purebred Swedish Red, and

Effect of genetic background, pen size and outdoor access on meat quality in two slow growing broiler hybrids Acta Agric. Scand. Sect. A Anim. Sci. (IF 0.9) Pub Date : 2021-01-05 S. Sampels, J. Pickova, S. Gatchell, A. Karlsson, J. Yngvesson, K. Arvidsson Segerkvist
ABSTRACT The aim was to evaluate the effect of two different rearing systems, indoor small pens (S) and big pens with outdoor access (B), on meat quality and fatty acid (FA) composition of two slow growing broiler hybrids (Rowan Ranger [RR] and Hubbard CYJA57 [H]). In addition, changes in the phospholipid FA composition, due to the possibility of more movement, were investigated. The results regarding

Physiological and behavioural responses of Swedish domestic goats and their kids (Capra hircus) to 15 days of heat exposure Acta Agric. Scand. Sect. A Anim. Sci. (IF 0.9) Pub Date : 2021-01-12 E. Hartmann, M. Högberg, K. Olsson, K. Dahlborn
ABSTRACT Seven Swedish domestic goats (Capra hircus, 2–3 years) and their kids (37 ± 4 days) were subjected to indoor temperatures above 30°C during 15 days (periods H1–H4; periods without heat C1, C2) to study acclimation. Rectal temperature (RT) increased by 1.1°C during H1 to H3 (P < 0.001 vs. C1), but only by 0.6°C during H4 (P < 0.001 vs. C1; P < 0.024 vs. H1). Respiration rate (RR) increased
