Egg mineral levels, hatching results and bone properties in embryos and chicks obtained from broiler breeders at different ages
AbstractIt is inevitable to obtain chicks from breeders of different ages in broiler fattening. However, breeder age has an effect on eggs. There is no detailed study on the changes in mineral levels in eggs and bones of these effects. Therefore, the aim of this study examines how mineral levels of shell, albumen, egg yolk, and bone, embryonic development and bone characteristics change according to the breeder age. A total of 370 fresh hatching eggs were obtained from Ross-308 breeders at 2 different ages (25 to 60-week-old). Egg, embryo, yolk sac and chick characteristics were determined. Morphometric parameters of bones...

A field study on the effects of inactivated bacteria vaccine for respiratory diseases in Japanese Black calves
This study evaluated the effects of vaccination forPasteurella multocida,Mannheimia haemolytica, andHistophilus somni in young Japanese Black calves at an ordinal farm, where respiratory diseases frequently occur at a young age. In total, 105 calves were divided into the vaccination group (n = 52), which received inactivated combined vaccine at 0 and 2 weeks of age, and the control group (n = 53), which received no vaccine. From both groups, eight calves each were randomly selected to determine the antibody titers. And, the incidence of respiratory disease and medical costs (treatment plus vaccination costs) were...

Effects of carotenoid supplementation on colour, growth and physiological function of the endemic dwarf chameleon fish (Badis badis)
AbstractThe global ornamental fish trade is expanding in response to increased demand for indigenous fish on the global market, while exogenous carotenoids can improve colouration. The 60-day trial investigated the effect of carotenoid supplementation, viaArtemia, on colouration, growth and immunophysiology ofBadis badis (dwarf chameleon fish). Carotenoid was enriched at 40 ppm (T1), 80 ppm (T2) and 120 ppm (T3) and compared with controls, C1 (unenriched) and C2 (oil-enriched). Fish larvae (average weight 0.12 g) were fed enriched–unenrichedArtemia in triplicates (5 × 3) in aquarium tanks (15 L). C1 and ...

In paired preference tests, domestic chicks innately choose the colour green over red, and the shape of a frog over a sphere when both stimuli are green
Anim Cogn. 2023 Aug 23. doi: 10.1007/s10071-023-01821-x. Online ahead of print.ABSTRACTMany animals express unlearned colour preferences that depend on the context in which signals are encountered. These colour biases may have evolved in response to the signalling system to which they relate. For example, many aposematic animals advertise their unprofitability with red warning signals. Predators' innate biases against these warning colours have been suggested as one of the potential explanations for the initial evolution of aposematism. It is unclear, however, whether unlearned colour preferences reported in a number of sp...

Stimulatory effect of dietary alpha ‐lipoic acid on growth performance, antioxidant capacity, liver enzymes, immunity and protection of African catfish, Clarias gariepinus (B.), Edwardsiella tarda infection
AbstractEdwardsiella tarda is one of the most common causes of fish diseases that hinder aquaculture. Oxidative stress in farm animals can induce a number of pathological disorders, production and general animal welfare. The use of exogenous dietary nonenzymatic antioxidants such as alpha-lipoic acid (ALA) can stop a pro-oxidant state and thus appears to have the potential to modulate the immune system and protect fish from bacterial infection. Thus, this study investigates the stimulat ory effect of dietary ALA on growth performance, antioxidant capacity, liver enzymes, immunity and protection of African catfish,Claria...

Autumn grass treated with a hydrolysable tannin extract versus lactic acid bacteria inoculant: Effects on silage fermentation characteristics and nutritional value and on performance of lactating dairy cows
In this study, two small bunker silos were filled with autumn grass. One was treated with 20 g/kg DM HT extract (TAN) (TannoSan-L), the other with 8 mg/kg DM inoculant containing lactic acid bacteria (INO) (Bonsilage Fit G). Secondly, micro-silos (2.75 L) were filled wi th four treatments; (1) grass without additive (CON) (n = 5); (2) TAN (n = 5); (3) INO (n = 5); and (4) TAN + INO (n = 5). The bunker silos were used in a cross-over feeding experiment with periods of 4 weeks involving 22 lactating Holstein cows (average ± SD: 183 ± 36.3 days in milk, 665 ± 71.0 kg body weight, and...

Evaluation of minimally invasive estrus synchronization protocols in brown brocket deer (Subulo gouazoubira)
This study aimed to evaluate minimally invasive protocols for estrus synchronization in the brown brocket deer (Subulo gouazoubira). Females were submitted to Latin square design, in different treatments. All females received 0.25 mg of estradiol benzoate on the first day of treatment, concomitant with one of the following sources of progesterone: (1) DIP: an intravaginal progesterone releasing device for eight days, (2) MGA1x: once a day (in the morning) oral dose of 1 mg melengestrol acetate for eight days, (3) MGA2x: twice a day (morning and afternoon) oral doses of 0.5 mg of MGA for eight days, (4) P4LA: a single i.m. ...
