The transmission of identical haplotypes from a common ancestor creates long stretches of homozygous genotypes, known as runs of homozygosity (ROHs). Longer haplotypes are inherited from recent common ancestors, and shorter haplotypes, from distant ancestors. In this study, we performed a comparative analysis of the genomic data of the Moura pig breed, a locally adapted breed from Brazil, that typically

Effects of agronomical selenium biofortification of Iberian pig diet on quality and antioxidant capacity of pork Livest. Sci. (IF 1.8) Pub Date : 2024-01-24 F.I. Hernández-García, J. Matías, M. López-Parra, J. García-Gudiño, C. Barraso, N. Garrido, A.M. García-Calvo, M. Izquierdo
Due to its valuable high intramuscular fat content and lipid composition, Iberian pork is very prone to rancidity. Selenium (Se) supplementation delays meat post-mortem oxidation, but organic Se reaches tissues more efficiently and durably than the inorganic forms, which may even be toxic at high concentrations. Agronomical Se biofortification (incorporating Se to crops) provides organic Se, is not

Modelling the physiological, muscular, and sensory characteristics in relation to beef quality from 15 cattle breeds Livest. Sci. (IF 1.8) Pub Date : 2024-01-04 J. Albechaalany, M-P. Ellies-Oury, J. Saracco, M.M. Campo, I. Richardson, P. Ertbjerg, S. Failla, B. Panea, J.L. Williams, M. Christensen, J.-F. Hocquette
Sensory beef quality is an important parameter for consumers, but it is difficult to understand what determines quality because of the large variation due to breed, type of animal, sex, and farm management. To address these challenges, meat samples from Longissimus thoracis (LT) were collected 24 h after slaughter from a total of 436 young bulls representing 15 cattle breeds. The samples were analysed

Mastitis is the most prevalent and costly production disease in the dairy industry, but udder health advice that helps one herd might not be beneficial for another because of “local truths”. It is therefore important to identify what mastitis control options may work in a specific herd in the conditions specific to the herd.

Feed and energy efficiency have been topics of extensive research in recent years, with residual feed intake (RFI) being the preferred index to determine feed efficiency in beef cattle. Nevertheless, the biggest downside of RFI is that its measurement requires accurately determining individual feed intake, which leads to the need to carry out RFI trials in confinement conditions.

A high-reactivity herd temperament reduces productivity and profitability in cattle farming. In Bos taurus indicus (Nellore) cattle, we hypothesized that a higher reactivity score is associated with a lower pregnancy rate, and that injectable supplementation with minerals (Cu, Zn, Mn, Se) and vitamins (A, E) would increase the pregnancy rate and reduce embryonic mortality in very reactive cows.

Heat stress is a major challenge for dairy herds and can lead to significant production reduction, mainly in tropical climate. Differences in decreased milk production in animals is associated with genetic variation. The overall goal was to investigate the effect of heat stress in milk yield of Girolando cattle in tropical climate and to identify the most appropriate statistical approach for evaluation

Effects of fermented bamboo powder on growth performance, apparent digestibility, carcass traits, and meat quality in growing-finishing pigs Livest. Sci. (IF 1.8) Pub Date : 2023-10-14 Zi Zheng, Zhengqun Liu, Ning Li, Shuqin Mu, Shiyue Liang, Zhonghao Liu, Chunhua Zhang, Yuanming Li, Jun Yan, Qianjun Li
The purpose of this experiment is to study the effects of fermented bamboo powder (FBP) on growth performance, apparent digestibility, carcass traits, and meat quality in growing-finishing pigs. A total of 72 barrows (initial body weight, 90.37 ± 0.73 kg) were randomly allocated to 4 dietary treatments in a 42 d trial, including a control (CON) diet and 3 FBP supplementation diets. In this experiment

Recording of culling reasons in Danish dairy cows Livest. Sci. (IF 1.8) Pub Date : 2023-10-18 Peter T. Thomsen, Hans Houe
Culling in dairy cows has major impacts on production economy and animal welfare, and has been described and evaluated in many studies. Information about why a cow is culled (culling reason) may be useful for many different purposes. Still, the present study is the first to evaluate explanatory factors for recording of culling reasons. Danish dairy farmers are required to report the culling mode (slaughter

Dietary influence of de-oiled lecithin on broiler growth, Blood parameters, Antioxidant status, Thyroid hormones and immunoglobulins: An analysis across two distinct strains of broilers Livest. Sci. (IF 1.8) Pub Date : 2023-10-10 Okasha H․M․, G.M. EL-Gendi, Zangabel S․M․, W. Abdelmoez, O.K. Abou-Emera, K.M. Eid
The objective of this study was to examine the impact of adding an emulsifier, de-oiled soybean lecithin (DOL) in diet, on growth performance, blood parameters, antioxidant potential, thyroid hormones (T3 & T4), and serum immunoglobulins in two distinct strains of commercially raised broilers, Ross 308 (S1) and Evian 48 (S2). A total of 800 one-day-old broiler chicks from both strains (N = 400 each)

Evidential segregation analysis for offspring sex ratio in rabbit and sheep populations Livest. Sci. (IF 1.8) Pub Date : 2023-10-07 Joaquim Casellas, Marta Vázquez-Gómez, Samir Id-Lahoucine, Melani Martín de Hijas-Villalba
Offspring sex ratio has been found to be altered by environmental and genetic distortions in multiple species, against the Mendelian inheritance rules. However, little is known in livestock populations where it is essential to validate whether a polymorphic major gene with relevant effects may segregate in the target population. However, the current analytical tool (model FREQ) cannot handle new mutations

Partial and total replacement of soybean meal with maggot larvae meal in broiler chicken diets: Impact on growth performance, nutrients digestibility, haemotological parameters and intestinal histomorphology Livest. Sci. (IF 1.8) Pub Date : 2023-10-07 Momin Khan, Naila Chand, Sarzamin Khan, Shabana Naz, Abdulwahed Fahad Alrefaei, Mikhlid H. Almutairi, Dai Sifa, Rifat Ullah Khan
Current study was carried out to investigate the effect of replacing soybean meal with maggot meal in broilers ration (Ross-308, n = 200) for 1–28 days. Five isocaloric and isonitrogenic broiler rations were prepared comprising of control diet-1 (Mag-0) having 100 % soybean meal and 0 % maggot meal, Diet-2 (Mag-70) having 30 % soy bean meal and 70 % maggot meal, Diet-3 (Mag-80) having 20 % soybean

Effect of co-mingling non-littermates during lactation and feed familiarity at weaning on the performance, skin lesions and health of piglet Livest. Sci. (IF 1.8) Pub Date : 2023-09-25 C. Van Kerschaver, M. Vandaele, K. Van Tichelen, Thomas Van De Putte, D. Fremaut, C. Van Ginneken, J. Michiels, J. Degroote
This study investigated how co-mingling of non-littermates before weaning and feed familiarity at weaning in a 2 × 2 factorial design can minimize the adverse effects related to conventional weaning. Before weaning, piglets were either conventionally reared or co-mingled by grouping piglets from 3 litters during 10 days before weaning. At weaning, piglets from 3 litters were distributed over 3 pens
