The aim of the present study was to demonstrate the influence of boar breed and season on semen parameters. The research material consisted of 31 boars: Polish Large White (PLW), Polish Landrace (PL), and Duroc × Pietrain (D × P),…
An experiment was conducted to investigate the effect of concentrations of certain blood nutrient-sensitive metabolites and the resumption of postpartum ovarian cyclicity in 16 Sanga cows (mean BCS 5). Blood samples were taken from cows from weeks 1 to 13…
This study was conducted to determine the effect on semen quality traits of supplementing the diets of Iraqi drakes with L-carnitine. Forty eight male Iraqi ducks, 30 weeks old, were randomly allocated to four treatments with 12 drakes per treatment…
The aim of the study was to evaluate the seasonal variation in semen quality of Dorper rams using different semen collection techniques. The study was carried out from January 2012 to January 2013. A general management programme for health control…
This study was carried out to investigate the effect of conventional farming systems for laying hens (standard cage batteries) and new alternative systems (improved cages and free range), approved by European Union (EU) poultry welfare legislation, on the chemical and…
The feral goats from Tankwa Karoo National Park in the Northern Cape, South Africa, constitute a potentially unique goat population, which dates back to the early 1900s, but is now at risk of extinction. A total of 66 feral goats…
The aim of the study was to determine the potential relationships between variants of the leukaemia inhibitory factor (LIF) gene and litter size in Landrace x Polish White sows. To identify polymorphisms within the LIF gene, the polymerase chain reaction–restriction…
Profitable milk production and genetic improvement in dairy herds depend largely on fertile cows calving annually to initiate a new lactation period. Over the last 30 years, several studies have indicated a decline in the reproductive performance of dairy cows.…
The objective of this study was to determine the physico-chemical characteristics and consumer sensory scores of chevon from crossbred Xhosa lop-eared goats supplemented with Moringa oleifera leaf meal (MOL). Twenty-four goats, aged 8 months, were divided into three groups with…
A study was conducted to evaluate the potential of macadamia oil cake meal (MOCM) and wood ash as feed ingredients for poultry under subsistence farming conditions. In this article, the effect of these ingredients on bone characteristics is reported. Two…
Within-litter birth weight variation in pigs is increasingly becoming important in influencing the profitability of pig enterprises. The objective of the study was to characterize within-litter birth weight variation in piglets from Large White × Landrace sows. The study was…
Genetic evaluation for the South African dairy industry has kept pace with global advances in statistical methodology. Increasingly accurate estimated breeding values (EBVs), produced routinely in the past two or three decades, have aided selection decisions. This has been coupled…
A study was conducted, first, to compare the gastrointestinal tract (GIT), reticulo-rumens and intestinal capacities (relative to body weight) of ram lambs from six Turkish sheep breeds: Turkish Merino (TM, Anatolia Merino), Akkaraman (AK), Kıvırcık (KV), Awassi (AW), Karayaka (KY)…
This study was aimed at determining the effect of housing systems on the growth, feed conversion ratio (FCR), meatiness and size of muscle fibres of Pekin (P44) and Muscovy (MR71) ducks. Each genetic group included 360 birds (180 males and…
The aim of this study was to assess the efficacy of the phytogenic product, Ruchamax® (Ayurvet, India), on the productivity of sows and the performance of their first litters. Ruchamax® contains a blend of herbal extracts from Adrographis paniculata, Phyllanthus…
The objective of this study was to evaluate the nutritive value of maize stover silage diets containing pig excreta (PE), poultry litter (PL) or urea as nitrogen (N) sources, and sugarcane molasses (MOL) or bakery by-products (BBP) as energy sources.…
The effects of in ovo amino acid administration on hatchability traits and post-hatch performance were studied using eggs from a meat-type breeder flock (Ross) at 38 weeks of age. On day 15 of incubation, five treatments were applied, consisting of…
This experiment was conducted with 480 Hubbard JA 957 one-day-old broiler chicks to determine the effects of adiCox®AP, a plant coccidiostat, and monensin on production parameters and meat quality. The birds were randomly allocated to three experimental diets: (A) with…
The main objective of this study was to estimate the genetic parameters for body measurement and yearling live bodyweight traits in the Makuie sheep breed. The data set consisted of 2 144 lambs from 122 sires and 984 dams recorded…
This study analysed the meat fatty acid (FA) composition of three zebu breeds, Gudali (GU), White Fulani (WF) and Red Mbororo (RM), raised on savannah pasture and monitored in the commercial context of the Yaoundé abattoir. Samples of m. longissimus…
