Abstract

Contents The objective of this study was to describe efficiency of reproduction of purebred dogs in field breeding conditions, from mating to weaning in France. Data were collected between 2010 and 2014 in 5,667 French breeding kennels via a reproduction management software (Breeding Management System, Royal Canin, Aimargues, France). Effect of breed size (Mini: adult body weight <10 kg; Medium: 10-25 kg; Maxi: 25-40 kg; Giant: >40 kg), age of dam and male on pregnancy rate, abortion rate and litter size were evaluated by multivariable models. Data on 45,913 heats (all with mating), from 27,221 bitches from 248 breeds, were analysed. At mating, mean age (± SD) was 3.1 ± 1.8 years for bitches and 3.3 ± 2.0 for males. Males originated from the same kennel as the females in 88.5% of the matings. Based on breeder's evaluation of the pregnancy status, pregnancy rate (number of pregnant females based on breeders declaration/number of heats) was 87.8% and abortion rate was 6.8%. Finally, 81.9% of the mated females gave birth to a litter. On 37,946 litters (204,537 puppies), mean litter size was 5.4 ± 2.8 puppies (range 1-24), which was influenced by breed size and dam age ( p < .0001). Stillbirth rate was 7.4% and puppy mortality rate (stillbirth + mortality until 2 months of age) was 13.4%. Prolificacy and puppy mortality rates were affected by breed size and within a breed size, by breed. Despite probable approximations (as data originate from breeders declaration), this large-scale analysis provides reference values on reproductive performance in dogs. [ABSTRACT FROM AUTHOR]

22. Canine and feline colostrum.

Abstract

Contents Puppy and kitten survival over the first weeks is particularly dependent on colostrum, a specific secretion of the mammary gland produced during the first 2 days post-partum. Colostrum is a source of nutrients and immunoglobulins. It also contributes to the digestive tract maturation. Colostrum differentiates from milk mainly based on its concentration in immunoglobulins G: 20-30 g/L in dog colostrum, 40-50 g/L in cats' vs <1 g/L in milk. IgG concentration rapidly drops after parturition (−50% in 24 hr). Immune quality of colostrum is highly variable between bitches, with no relationship with maternal blood IgG level, dam's age, breed size or litter size. In addition to systemic immune protection, colostrum also plays a major role for local digestive protection, due to IgA, lysozyme, lactoferrin, white blood cells and various cytokines. Energetic concentration of canine and feline colostrum is not superior to that of mature milk. It depends on colostrum fat concentration and is affected by breed size (higher in breeds <10 kg adult body weight). As puppies and kittens are almost agammaglobulinemic at birth, transfer of IgG from their digestive tract into their bloodstream is crucial for their survival, IgG absorption ending at 12-16 hr after birth. Energetic supply over the two first days of life, as evidenced by growth rate over the two first days of life, also affects risk of neonatal mortality. Early and sufficient suckling of colostrum is thus the very first care to be provided to newborns for their later health and survival. [ABSTRACT FROM AUTHOR]

Abstract

Contents Colostrum and milk are complex mammary secretions providing the puppy with many nutritional and immunological factors, which play a crucial role for its correct development and survival. In the case of colostrum and/or milk intake deficiency, puppies are at increased risk of infectious diseases. This work reviews the various nutritional hyperimmune supplementations proposed to provide a passive immune protection and to positively impact puppies' health. Some strategies rely on canine immunoglobulins: canine colostrum banking and canine serum/plasma supplementation. Others involve heterologous sources of antibodies and other immune factors: bovine colostrum or hyperimmune egg powder. Among the different solutions evaluated from birth to weaning, canine plasma and hyperimmune egg powder showed promising beneficial effect on puppies' health. Canine plasma seems to positively impact not only growth (increased growth during the neonatal period), but also digestive health (higher species richness of intestinal microbiota) and the general health (tendency of lower morbidity). Puppies supplemented with hyperimmune egg powder presented increased neonatal growth and decreased risk of canine parvovirus infection. Nevertheless, natural canine maternal colostrum and milk ingestion remains the optimal guarantee for puppies' health and survival, as a source of immunity, energy and growth factors.

Abstract

Contents Reproduction management and performances are evaluated in the feline species only through a limited number of animals and studies. Our objective was to provide reference figures in purebred cats, from a large-scale sample. Data were collected from an online software dedicated to cattery management (Breeding Management System®, BMS, Royal Canin, Aimargues, France). Information was recorded on a voluntary basis by French breeders between 2011 and 2014. Data were anonymously transferred for analysis. A total of 9,063 oestrous periods (in contact with a male) from 5,303 queens (45 breeds) were recorded from 1,521 breeders. Most matings (70.1%) occurred during increasing day length periods. The mean age at mating (± SD) was 2.7 ± 1.6 years for queens and 2.9 ± 1.9 years for tomcats. Pregnancy rate (based on breeders declaration) was 85.2%. Among queens declared pregnant, 8.4% failed to maintain pregnancy. Globally, 78% of the mated females gave birth to 28,065 kittens within 7,075 L. Mean litter size was 4.0 ± 1.9 kittens among which 8.5% were stillborn. Neonatal and paediatric mortality rate was 8.2%. In total, 16.0% of kittens born died before weaning. The results of this study are based on the largest feline database ever analysed. The figures collected can thus be used as reference to define average reproductive performances in numerous breeds for cat breeders. Further analysis will identify factors influencing reproductive performances and early mortality in the feline species. [ABSTRACT FROM AUTHOR]
