“…In contrast with T4 results, our study refuted any correlation between the concentration of GH and the age of investigated sheep at birth, weaning, and six months' age. These results are also supported in Norduz Sheep (Karakuş et al, 2017).…”

This study was conducted in the animal field of the Al-Kafeel Company from November 2019 till May 2020 to investigate the possible association between growth hormone (GH) and thyroxine (T4) with the growth traits in Awassi and Karakul sheep. The total number of animals which used in the study was 60 lambs, 28 (13 males and 15 females) from Karakul and 32 (18 males and 14 females) from Awassi. Blood samples were collected at birth, weaning, and six months of age, and both GH and T4 concentrations were measured. Results showed higher values of T4 for Karakul as compared with Awassi at birth and weaning. Karakul breed was also exhibited significantly higher values of GH over Awassi breed only at weaning, while, no significant differences were observed at birth and six months of age. Karakul lambs showed higher weights as compared with Awassi lambs at all studied periods. A highly significant (p < 0.01) positive correlation was observed between T4 concentration and the weight of lambs at most studied periods. Whereas, GH did not exhibit any correlation with growth traits measured in both breeds. The elevated T4 might be one of the reasons for superiority of Karakul over Awassi breed in live body weights. This high correlation between T4 and growth traits could be used in the early selection of lambs to improve the weights of sheep at marketing.

“…As expected, males were heavier than females and SI was heavier than MN breed. The serum testosterone level, the male sex hormone, is positively correlated with body weight gains of sheep (Karakuş et al, 2017). The SI breed had the highest average body weight, because it has larger body size and percentage of bone than the MN breed (Araújo Filho et al, 2010).…”

This study aimed to evaluate the influence of tactile stimulation and halter walking trainings in the temperament, physiology, behavior and body weight of sheep. A total of 80 sheep, males and females, of the Morada Nova (MN) and Santa Ines (SI) breeds, with initial ages of six to eight months, were trained with tactile stimulation (TS), halter walking (HW) or tactile stimulation and halter walking (TS+HW). The control (C) animals were not submitted to any kind of training. The behavioral aspects were measured by application of a open-field test, to quantify the traits movement, vocalization, escape attempt and digging, and the temperament test, with assignment of a temperament score for each animal. The animals were weighed and rectal temperature, heart rate and respiratory rate were measured. Males were more reactive than females to human. Animals trained with TS were the least reactive in the temperament test, while the most reactive animals were SI male from C and TS+HW treatments. Males of treatments C and HW were the heaviest during the study. The animals in the control group showed higher averages for heart rate and rectal temperature, while animals trained with TS and HW showed the lowest values. Females MN trained with TS and TS+HW moved more during the open-field test, while the SI females of the control group moved less. The SI animals vocalized more during the open-field test, both from treatment C and from TS+HW. The MN animals from C treatment vocalized less. Sheep trained with tactile stimulation were more docile. The training with tactile stimulation and halter walking in Santa Ines and Morada Nova sheep influenced the heart rate, rectal temperature, moviment, vocalization, escape attempt and body weight.

“…The administration of these chemical agents is done through a single dose for sterilization (KARAKUS et al, 2017;VARGAS et al, 2020), having as proof of effectiveness the confirmation of the absence of reproductive function in the animals tested, safety test to animals and the environment, in addition to irreversible results after administration (OLIVEIRA et al, 2012).…”

Chemical castration has been an alternative to reduce costs for producers and improve animal welfare. The clove (Eugenia caryophyllata) has several therapeutic potentials, among which there are reports of sterilizing potential. The aim of this study was to evaluate the potential sterilizing effect of clove (Eugenia caryophyllata) essential oil in pigs, in order to reduce costs to producers while at the same time following animal welfare guidelines. Twenty pigs were randomly selected and divided into four equal groups. Clove oil was administered at two concentrations in the animals of two groups (G1 = 0.07 mL/kg; G3 = 0.3 mL/kg) and saline solution at different concentrations in the two remaining groups (G2 = 0.07 mL/kg; G4 = 0.3 mL/kg). At 60 days after induction of chemical castration, the animals underwent orchiectomy, a procedure in which the testicles were collected for histological processing. Histopathology revealed that none of the concentrations used was able to induce chemical sterilization of the animals, different from what was expected. It is concluded that the chemical castration technique is easy to perform, but the clove essential oil was not able to induce chemical sterilization in animals at the concentrations in which was used.
