Zamuner F, Leury BJ, DiGiacomo K. Review: Feeding strategies for rearing replacement dairy goats - from birth to kidding. Animal 2023; 17:100853. [PMID: 37271015 DOI: 10.1016/j.animal.2023.100853] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2022] [Revised: 05/02/2023] [Accepted: 05/04/2023] [Indexed: 06/06/2023] Open
Abstract
Goat kid rearing is a key profit driver and the cornerstone of future herd productivity in dairy systems. As goat kids get older, and progress from liquid (i.e., colostrum, milk) to solid feed (i.e., concentrate, hay, pasture), there is a reduction not only in feed cost but also in labour cost, disease susceptibility and mortality rates. Hence, research on rearing dairy goats has traditionally focused on improving early neonatal performance. However, recent research reveals that early-life nutrition may have long-term effects, and consequently, impact the lifetime productive performance and health of dairy goats. Therefore, this literature review has collected research on the various aspects of rearing replacement dairy goat kids in different production systems. It summarises research on areas such as colostrum management (i.e., colostrum quality, time, volume and frequency of colostrum feeding), liquid feeding in preweaned kids (i.e., maternal suckling vs artificial, restricted vs unrestricted), weaning strategies (i.e., abrupt vs step-down), and postweaning to postpubertal nutrition in replacement dairy goats, whilst highlighting gaps in the existing literature, and areas where it would be beneficial to refine and validate current recommendations. Such information can be used in the development of management plans to maximise the benefits of early-life nutrition on the long-term productivity of dairy goats.

[PMID: 35153412 PMCID: PMC8829410 DOI: 10.14202/vetworld.2021.3194-3199] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2021] [Accepted: 11/17/2021] [Indexed: 11/16/2022] Open
Abstract
Background and Aim: Immunoglobulin G (IgG) concentration is high in goat colostrum, particularly in the first few hours after parturition, and this is important for the kid’s immunity and growth. IgG levels vary depending on several factors, including breed, disease status, colostrum management, handling, and collection time postpartum. A handheld optical refractometer, an affordable instrument that is simple to use in the field, is used widely in dairy farms to measure total solids. However, it can also be applied to estimate colostrum IgG content on the basis of comparison with standard measurement methods, usually radial immunodiffusion. Studies comparing %Brix values in relation to IgG concentration measured using enzyme-linked immunosorbent assay (ELISA) in goats are limited. The present study aimed to evaluate the use of a handheld optical Brix refractometer for the measurement of IgG concentration in goat colostrum, compare results with those using ELISA, and estimate the %Brix cutoff value equating to low-quality colostrum. Materials and Methods: Colostrum samples were collected on day 0 from 21 goats (nine Black Bengal, six Saanen, and six of their crossbred offspring) and were frozen. Subsequently, they were analyzed for IgG concentration using a goat-specific ELISA test and Brix percentage using a handheld refractometer. The optimum %Brix cutoff value for the evaluation of colostrum quality was evaluated. Results: The mean IgG concentration and %Brix in colostrum were 10.60±0.64 mg/mL and 25.0±0.9, respectively. There was a significant (p<0.01) correlation between %Brix and IgG concentration. For an IgG concentration of 6.9 mg/dL, the cutoff value for %Brix was 18.5, equating to high specificity (100%) but low sensitivity (50%). A higher %Brix cutoff value of 21.5 showed high specificity (95%) and high sensitivity (100%). Conclusion: A Brix refractometer can be used to estimate goat colostrum quality with a proposed %Brix cutoff value of <18.5%-21.5% for poor-quality colostrum.

Abstract
Dairy goat kid rearing is the foundation of future milk production, yet little is known on this topic. References available to producers are limited, making it more difficult for dairy goat farms to reach their full production potential. This review paper aimed to identify the current recommendations on dairy goat kid rearing practices for intensive production systems and to assess whether the different recommendations were based on scientific literature. Recommendations on dairy goat kid rearing practices, from birth to weaning inclusively, were presented and compared between countries under similar intensive production systems, including Canada, the United States, and France. The different areas of rearing investigated included kidding management, colostrum management, liquid and solid feeding, health management, disbudding, housing, weaning, and growth monitoring. Gaps in the literature were identified in all areas except for disbudding. More research on the topic of goat kid raising practices would be beneficial to refine and validate current recommendations.

Abstract
Colostrum and milk feeding are key factors for the newborn ruminant survival, affecting the future performance of the animal. Nowadays, there is an increasing interest in the potential of feeding newborn ruminants (mainly goat kids and lambs) with colostrum and milk from other more productive ruminant species (mainly cows). Although some studies regarding differences between colostrum and milk from these three species have been performed, herein we conduct for the first time a comparison using a proteomics 2-Dimensional Electrophoresis gel-based approach between these three ruminant species. In this study colostrum and milk samples from six Holstein cows, six Canarian sheep and six Majorera goats were used to determine the chemical composition, immunoglobulin G (IgG) and M (IgM) concentrations and proteomics profiles. Results showed that in general sheep colostrum and milk contained higher fat, protein and lactose percentages compared to bovine and goat samples. Additionally, no differences in the IgG or IgM concentrations were found among any of the three studied species, with the exception of sheep colostrum that showed the highest IgM concentration. With reference to the proteomics-based approach, some high abundant proteins such as serum albumin precursor, beta-caseins or different immunoglobulins components were found in colostrum, milk or even both. Nevertheless, differences in other proteins with immune function such as serotransferrin or lactoperoxidase were detected. This study shows that despite the similar immunoglobulin concentrations in colostrum and milk from the three studied species, differences in several immune components can be detected when these samples are studied using a proteomics approach. Finally, this study also provides a base for future investigation in colostrum and milk proteomics and metabolomics.

Abstract
The aim of the study was to evaluate the influence of soybean trypsin inhibitor (TI) on immunoglobulin G (IgG) serum levels and growth in neonatal goat kids. Twenty-four newborn kids were fed with natural colostrum (group A), and 24 kids received the same colostrum with 1 g of TI per litre (group B). Blood samples were obtained at birth and on days 1, 2 and 4 of life to analyze serum proteins, IgG and haematological parameters. There were no clinical signs of disease and no significant differences in body weight between the groups. Haematological parameters were not affected by treatment. The peak of serum IgG was reached at 24 h of life, but no effects of soybean TI was observed on serum IgG levels. The apparent efficiency of absorption of IgG was similar in both groups (group A 24.5% vs. group B 25.2%, p > 0.05). The addition of TI to colostrum did not change the concentration of serum proteins and their fractions in goat kids. The correlation between serum IgG and gamma-globulin was positive and significant (p < 0.01, r = 0.64) in group A, but not in group B (p > 0.05, r = 0.08), suggesting a negative influence of soybean TI on gamma-globulin absorption. These results show that addition of soybean TI to colostrum did not improve the performance or immunological status in goat kids.

Abstract
The aim of the research was to evaluate the effects of immunoglobulin G (IgG) colostrum concentration on goat kid immune status when the total amount of IgG fed was constant. Majorera goat kids (n = 56) were randomly assigned to 1 of 4 groups, and kids received 4 g of IgG per kg of body weight of atomized colostrum at 4 different IgG concentrations: 20 (AC-20), 40 (AC-40), 60 (AC-60), and 80 (AC-80) mg/mL. Blood samples were obtained on d 0, 1, 2, 3, 4, and 5 postpartum. Immunoglobulin G, IgA, and IgM plasma concentrations, apparent efficiency of absorption of IgG, plasma chitotriosidase activity, plasma complement activity, and plasma proteinogram were measured. Plasma IgG and IgM concentrations were highest on d 1 in AC-80 animals, and IgA plasma concentration was lower in AC-20 than in AC-80. The apparent efficiency of absorption was higher in AC-80 (24.4%) than in the other treatment groups (by an average of 13.8%). Chitotriosidase plasma activity on d 5 (1,488 nmol/mL per hour) was higher than on d 0 and 1 (average of 1,183 nmol/mL per hour). There were no effects of colostrum IgG concentration on complement activity and plasma protein distribution, but gamma-globulin and alpha-globulin were lower on d 0 than on d 1, 2, 3, 4, and 5. Increasing the immunoglobulin concentration in colostrum using atomized colostrum improves the immunoglobulin absorption at the same amount of immunoglobulin fed.
