Effects of heat-stress-reducing systems on blood constituents, milk production and milk quality of Holstein and Jersey cows and heifers on pasture
The objective of this study was to evaluate the influence of different heat-stress-reducing systems, i.e., sprinkler  + artificial shade, shower + artificial shade, and artificial shade, on serum mineral, hormonal, hematological, and metabolite profiles, on milk production, and milk composition in lactating cows and pubertal heifers of Holstein and Jersey breeds. For this purpose, 12 animals were used: 3 H olstein cows with an average (mean ± SD) body weight of 600 ± 30 kg, 53 ± 11 months of age, and milk yield of 27 ± 3.5 kg/day; 3 Jersey cows with an average body weight of 370 ± 11 kg...

Effects of feeding diets with zinc-l-selenomethionine on growth performance of broilers subjected to cyclic heat stress
In conclusion, the inclusion of 1.30 mg/kg of Zn-L-SeMet in diets of heat-stressed broilers improved growth performance from 1 to 42 days of age. An inclusion of 0.71 mg/kg reduced mortality rate, while 0.97 mg and 1.19 mg increased and reduced TRG and GGT levels, respectively. (Source: Tropical Animal Health and Production)

Gallibacterium anatis infection in poultry: a comprehensive review
AbstractGallibacterium anatis (G. anatis), a member of thePasteurellaceae family, normally inhabits the upper respiratory and lower genital tracts of poultry. However, under certain circumstances of immunosuppression, co-infection (especially withEscherichia coli orMycoplasma), or various stressors,G. anatis caused respiratory, reproductive, and systemic diseases. Infection withG. anatis has emerged in different countries worldwide. The bacterium affects mainly chickens; however, other species of domestic and wild birds may get infected. Horizontal, vertical, and venereal routes ofG. anatis infection have been reported. Th...

The comparative effect of creep and conventional feeding methods on growth performance and oxidative stress markers in Akkaraman lambs
This study aimed to determine the effect of conventional and creep-feeding methods on growth performance and oxidative stress in Akkaraman (AKK) lambs. For this purpose, the AKK lambs (n = 60) used in this study were divided into four groups (15n× 2 sex × 2 feeding methods), and all of them were fed the same ration. In the conventional feeding method, the lambs were taken to their dams for suckling twice a day and then kept in a separate compartment for further feeding. In contrast, in the creep-feeding method, the lambs always stayed wit h their mothers and had free access to supplementary feed by passing through the cr...

Effect of dietary onion (Allium cepa L.) powder as an antioxidant on semen quality, blood biochemicals, and reproductive parameters, as well as immunological variables of rabbit bucks under severe heat stress
In conclusion, dietary supplementation with onion powder at 400 or 800 mg/kg diet improves semen quality, RBC, FSH, LH, SOD, catalase, and IgG while ameliorating the adverse effects of heat stress and improve the health and reproduction of rabbits.Graphical abstract (Source: Tropical Animal Health and Production)

Utilizing intramammary Melaleuca alternifolia as an organic internal sealant for dry-off therapy in Murrah buffaloes
AbstractThe effects of intramammary dry cow therapy based on the administration of 5%Melaleuca alternifolia tea tree essential oil (TTO) as an internal teat sealant to Murrah cows were evaluated. A longitudinal prospective and retrospective negative control study was performed using 12 buffaloes from a total of 20 Murrah buffaloes on an organic farm, with the cow used as a control for herself. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) for treatments with pure oil (TTO) and medication containing 5% TTO (O5) were determined. The buffaloes were clinically examined, and the teats w...

Sustainable utilization of unsaleable walnut kernel in substitution for corn grain in the diet of fattening lambs improves growth performance and meat quality
AbstractAs a cost-effective typical co-product of walnut processing; this study aimed to investigate the effects of feeding poor quality, unsaleable walnut kernel, also known as wasted walnut (WW) kernel, on growth performance, carcass characteristics, meat quality and fatty acid (FA) composition of fattening lambs. The experiment was conducted using 24 fattening lambs (27 ±1.07 kg initial BW) assigned to two total mixed concentrate-based diets, over a 80-day experimental period on a completely randomized design. Dietary treatments were: 1) WW (10% WW), and 2) CON (without WW). Average daily and total gain, and final weig...

Feed resources used for small ruminant nutrition in Sub-Saharan Africa: a case study of Uganda
This study involved a comprehensive review of various scientific, technical and economic literature that has been published up to date. Our results show that the available feed resources in Uganda can be grouped mainly into:- crop wastes and residues, agro-industrial by-products, conserved feeds, natural pastures and browse. The main feed resources for small ruminants in Uganda have been identified as natural pastures, which are generally characterised by a low nutritive value. However, browses are seen to have a high crude protein content and could be used as a supplement to grass forages and crop residues. It has been no...

Improving the productive performance of growing lambs using prebiotic and probiotic as growth promoters
Abstract  The feed additives (prebiotics and probiotics) are used to stabilize the healthy gut microbiome by supporting beneficial microorganisms, thereby improving the animal growth rate. Thirty growing lambs, with around 20.50  ± 0.65 kg live weight were placed into five equal groups (6 animals each). The concentrate feed mixture (CFM) + roughage was given to the control groups. The treatments (T) of T1, T2, and T3 treatments were fed the control ration with three levels of prebiotic supplementation: 0.50, 1.00, and 1.50 g/kg CFM of mannan oligosaccharids + beta glucan, respectively. The T4 received the con...

Effects of prenatal dichromatic light exposure on hatching results and post-hatch performance of Japanese quail
AbstractPresent study evaluated the effect of lighted incubation on pre- and post-hatch performance of Japanese quail. In a completely randomized design, 1200 eggs were evenly divided into 4 treatments groups having six replicates (each tray was considered as replicate), 50 eggs each. Different dichromatic lights (Green + Red; GR, Green + Blue; GB, and Blue + Red; BR) of 250 lux were provided during incubation for 12 h daily and effects of these lights very evaluated on hatching results and post-hatch growth. After hatch, 600 quail chicks were divided into 4 treatments, 6 replicates, and 25 birds each. Regarding hatching t...

Thermography as an indicator of goat welfare in an intensive production system
This study evaluated the welfare of Saanen, Moxoto, and Anglo-Nubian goats kept in collective or individual pens for a feedlot system, evaluated with infrared thermography. A total of twenty-four goats were used, eight for each breed. Animals were distributed in a completely randomized design, with a 2 × 3 factorial with two fixed effects: housing type (collective or individual pens) and breed (Moxoto, Saanen, and Anglo-Nubian). The surface temperature was evaluated using an infrared thermographic camera, and behavioral analysis was based on the qualitative behavior assessment using a fixed list of descriptors. The breed ...
