“…Animals' physiological, physical, and psychological condition changes if their welfare is affected due to environmental changes, injury, illness, tension, or other reason, consequently resulting in behavioral changes. Ribeiro et al, (2006) and Silva et al, (2014) stated that behavioral analyses build knowledge about normal animal behaviors that can be transferred to producers, which in turn may use it to identify abnormal behaviors and seek for palliative measures to solve the problem. The mainly purpose of providing environmental enrichment is to allow animals to express their natural behavior, propitiating their welfare as far as possible (Ribeiro et al, 2006).…”

The objective of the present study was to evaluate the behavior of lactating Saanen dairy goats housed with or without the use of environmental enrichment technique. Twelve animals were split into two equal groups and assign to one of two treatments: stall with or without enrichment. Five objects were used to enrich the stalls: plastic PET bottles suspended and freely on the floor (both filled with corn as a visual and auditory stimuli), general cleaning brushes fixed to the wall of the stall, suspended tire, and a tree trunk for climbing. The behavior of the goats was observed during two hours for 10 consecutive days. The behaviors were recorded using focal-animal sampling method, observing each animal during 10minute period. Descriptive statistics were calculated plotting the results in behavior frequency charts. Animals on both treatments showed similar behaviors frequencies for food intake and self-cleaning. However, a higher frequency of stereotyped behaviors was registered in the treatment without environmental enrichment. The highest frequency of interaction was observed for suspended tire, indicating animal's preference for this object. In conclusion, animals on enriched environment show more different behaviors than animals in non-enriched environment and showed greater preference for some object over others.

“…An increase in plasma CK concentration is observed if mus-cle damage occurs or high physical activity exists. The increase in plasma LDH level is mainly caused by tissue damage (Bórnez et al, 2009;De la Fuente et al, 2010;Kannan et al, 2003;Tadich et al, 2009). In the current study, the fact that both the fattening week and breed had no effect on plasma CK and LDH suggests that the animals were not exposed to strenuous muscle activity during the fattening period.…”

Haematological stress parameters and behavioural characteristics of dairy type goat kids compared to indigenous breeds during an intensive fattening programme

Abstract. In any production model, the extent to which the animals cope with the environment is important in terms of animal welfare and sustainability of production. The aim of the study was to investigate certain haematological parameters and behaviours of goat kids from dairy type Saanen and Maltese breeds via comparison with indigenous Hair and Gokceada breeds during the 10-week intensive fattening period. Eleven male goat kids each of Saanen, Maltese, Hair and Gokceada breeds were weaned at 3–3.5 months of age and then placed into four fattening pens prepared for each breed, separately. Cortisol, glucose and total protein levels were higher in Gokceada kids in the last period of the fattening compared to the kids of other breeds (P<0.05). In Gokceada kids, an evident decrease in the time spent hay feeding and on rumination and an increase in lying, standing and self-grooming behaviours were determined during the last 3 weeks of fattening. Moreover, there was a significant decrease regarding hay feeding in Hair goat kids in the last 2 weeks (P<0.05). Hair goat kids also exhibited less rumination behaviour compared to Saanen kids during the last 4 weeks of fattening (P<0.05). On the other hand, kids of dairy breeds did not express behavioural or biochemical stress responses during the fattening period. As a conclusion, when evaluated in terms of animal welfare, results of the current study may indicate that indigenous breeds, especially Gokceada kids, are not appropriate for intensive fattening in a pen.

“…To capture images, we used a smartphone (Moto X model; Motorola Mobility LLC, Chicago, Illinois, USA), with a 13 megapixels camera, supported on the second step, 0.15 m away from the seed line, so that the lens remained on the seed lines. The images were captured in an environment with only one light source, close to the platform, in order to avoid shadows in the images, as recommended by Silva et al (2014b). The central seed and the ones at the two ends were measured with a digital caliper (Mitutoyo; Sakado, Saitama, Japan) with a 0.01 mm resolution for image validation.…”

The quality of sesame (Sesamum indicum L.) seeds is directly influenced by their physical characteristics, which are seldom studied notwithstanding their extreme importance in the entire production chain. Therefore, the objective of this study was to quantify the physical properties of two types of sesame seeds, collected at three points in the plant with different maturation levels, measured with digital caliper, and to evaluate the feasibility of using a digital image to determine their physical characteristics. The seeds were initially evaluated for water content and mass of 1000 seeds, and later with the data of the characteristic dimensions A (length), B (width), and C (thickness), obtained by a caliper and digital images, we determined their sphericity, circularity, projected area, and geometric diameter. We observed that water content did not affect the physical properties of the cream (CNPA G4) and black sesame cultivars. In addition, seeds of the black cultivar presented higher results than the seeds of the cream cultivar for the mass of 1000 seeds (2.7 ± 0.08 g), sphericity (58.8 ± 0.47%), projected area (4.03 ± 0.12 mm 2 ), and geometric diameter (1.65 ± 0.03 mm). Seed batches harvested after 70% maturation had the highest mass of 1000 seeds (2.7 ± 0.12 g). The results of the physical analyses of sesame seeds performed with caliper and digital image are equivalent, which shows that digital images can be used as tools to obtain the physical properties of seeds.
